For the first time, the World Health Organization is taking steps to eliminate a substance that leads to a non-communicable disease: heart disease.
The World Health Organization Director-General Dr. Tedros Adhanom Ghebreyesus announced a plan Monday to eliminate trans fat from the global food supply by 2023.
Trans fat raises LDL, the “bad” type of cholesterol, and increases the risk of heart disease and stroke. Trans fat also reduces the amount of HDL, the “good” cholesterol that protects your heart.
Trans fat is artificially made. Liquid vegetable oils are processed with hydrogen to produce a solid fat, like stick margarine or ghee, which is frequently used in south Asian cooking. Trans fat is often present in snack foods like potato chips, baked foods, crackers and fried foods.
The advantages of trans fat is that it is cheap, lasts longer than natural oils, can be heated and reheated over and over again, and it’s almost ideal for making baked goods. “Almost” because it can kill you.
WHO estimates that every year consumption of trans fat leads to more than 500,000 deaths from cardiovascular disease.
At his announcement at WHO headquarters in Geneva Monday, Ghebreyesus asked, “Why should our children have such an unsafe ingredient in their foods?”
Several high-income countries have virtually eliminated industrially produced trans fat through legally imposed limits on the amount that can be contained in packaged food.
Denmark, the first country to do it, saw a marked decline in deaths from cardiovascular disease. Then other countries followed Denmark’s lead. About 40 countries currently have laws banning trans fat.
Dr. Tom Frieden, former head of the Centers for Disease Control and Prevention, joined Ghebreyesus at the rollout of the WHO program. Frieden now heads a nonprofit called “Resolve to Save Lives.” He told VOA, “We estimate that if trans fat is eliminated, 17 million lives will be saved over a 25-year period.”
Frieden was behind the initiative to get trans fat banned in New York City, prior to joining the CDC, when he was the city’s health commissioner.
“Trans fat is tasteless. It’s solid at room temperature, but it’s also solid at body temperature in your coronary arteries,” he said. “Trans fat is an unnecessary toxic chemical that kills, and there’s no reason people around the world should continue to be exposed.”
Frieden also said it is easy and inexpensive to replace trans fats with healthier oils.
More than 80 percent of deaths from cardiovascular disease are estimated to occur in low- and middle-income countries, according to a 2014 study published in the New England Journal of Medicine.
The WHO initiative, called REPLACE, calls on countries to implement six strategies.
REview dietary sources of industrially produced trans fats and the landscape for required policy change.
Promote the replacement of industrially produced trans fats with healthier fats and oils.
Legislate or enact regulatory actions to eliminate industrially produced trans fats.
Assess and monitor trans fats content in the food supply and changes in trans fat consumption in the population.
Create awareness of the negative health impact of trans fats among policymakers, producers, suppliers and the public.
Enforce compliance of policies and regulations.
Although trans fat is present in cheese and other dairy products and in some meats, the amounts are so small that it is not considered dangerous.

A new look at old data is giving scientists a fresh reason to view Europa, a moon of Jupiter, as a leading candidate in the search for life beyond Earth, with evidence of water plumes shooting into space.
A bend in Europa’s magnetic field observed by NASA’s Galileo spacecraft during a 1997 flyby appears to have been caused by a geyser gushing through its frozen crust from a subsurface ocean, researchers who reexamined the Galileo data reported on Monday.
Galileo was passing some 124 miles (200 kilometers) above Europa’s surface when it apparently flew through the plume.
“We know that Europa has a lot of the ingredients necessary for life, certainly for life as we know it. There’s water.
There’s energy. There’s some amount of carbon material. But the habitability of Europa is one of the big questions that we want to understand,” said planetary scientist Elizabeth Turtle of Johns Hopkins University Applied Physics Laboratory.
“And one of the really exciting things about detection of a plume is that that means there may be ways that the material from the ocean — which is likely the most habitable part of Europa because it’s warmer and it’s protected from the radiation environment by the ice shell — to come out above the ice shell.
And that means we’d be able to sample it,” Turtle told a NASA briefing.
The research, headed by University of Michigan space physicist Xianzhe Jia, was published in the journal Nature Astronomy.
The findings support other evidence of plumes from Europa, whose ocean may contain twice the volume of all Earth’s oceans.
NASA’s Hubble Space Telescope in 2012 collected ultraviolet data suggestive of a plume.
NASA will get a close-up look from a new spacecraft during its Europa Clipper mission that could launch as soon as June 2022, providing a possible opportunity to sample plumes for signs of life, perhaps microbial, from its ocean.
Europa is considered among the prime candidates for life in our solar system, but is not the only one. For example, NASA’s Cassini spacecraft sampled plumes from Saturn’s ocean-bearing moon Enceladus that contained hydrogen from hydrothermal vents, an environment that may have given rise to life on Earth.
A bit smaller that Earth’s moon, Europa’s ocean resides under an ice layer 10 to 15 miles (15 to 25 km) thick, with an estimated depth of 40 to 100 miles (60 to 150 km).

Congo has agreed to allow the World Health Organization to use an experimental Ebola vaccine to combat an outbreak announced last week, the WHO director-general said Monday.
The aim is for health officials to start using the vaccine, once it’s shipped, by the end of the week, or next week if there are difficulties, said WHO Director-General Tedros Adhanom Ghebreyesus.
“We have agreement, registration, plus import permit — everything formally agreed already. And as you know that vaccine is safe and efficacious and has been already tested. So I think we can all be prepared,” he said. “All is ready now, to use it.”
The outbreak was announced last week in Bikoro, in Congo’s northwest. Health officials traveled there after Congo’s Equateur provincial health ministry on May 3 alerted them to 17 deaths from a hemorrhagic fever.
As of May 13, Congo has 39 suspected, probable and confirmed cases of Ebola since April, including 19 deaths, WHO reported. Two cases of Ebola have been confirmed.
Congo’s Ministry of Health has requested that WHO send 4,000 doses of the vaccine, said ministry spokeswoman Jessyca Ilunga, who said they should arrive by the end of the week.
“The vaccination campaign starts next week, everything depends on the logistics because the vaccine must be kept at minus 60 degrees Celsius, and we need to assure that the cold chain is assured from Geneva to Bikoro,” she said.
The Ebola vaccination campaign will first target health workers, Ilunga said. Three nurses are among those with suspected cases, and another is among the dead.
The teams on site have already identified more than 350 contacts, who are people who have had contact with the patients, she said.
Mobile laboratories were deployed to Mbandaka and Bikoro on Saturday, she said, adding that results from the first 12 samples tested with that method should be available tomorrow.
This is the ninth Ebola outbreak in Congo since 1976, when the deadly disease was first identified. Congo has a long track record with Ebola, WHO said. The last outbreak that was announced a year ago, was contained and declared over by July 2017.
None of these outbreaks was connected to the massive outbreak in Guinea, Liberia and Sierra Leone that began in 2014 and left more than 11,300 dead.
There is no specific treatment for Ebola, which is spread through the bodily fluids of people exhibiting symptoms.
The new experimental vaccine, developed by the Canadian government and now licensed to the U.S.-based Merck and has been shown to be highly effective against the virus. It was tested in Guinea in 2015.
Though the Congo outbreak is of a different strain, the experimental vaccine is still thought to be safe and effective.
WHO chief Tedros had led a delegation to the affected region on Sunday.
The Bikoro health zone is about 150 kilometers (93 miles) from Mbandaka, the capital of the Equateur province, and 45 kilometers (28 miles) from Ikoko Impenge, where there are other suspected cases.
WHO is working with Congo’s government and other international organizations, including Medecins Sans Frontieres (Doctors Without Borders), to strengthen coordination to fight and contain the Ebola outbreak.
Kenya’s government is pushing ahead with a plan to hire 100 Cuban doctors despite opposition from a doctors’ union that says the money could be used to employ local physicians instead.
President Uhuru Kenyatta agreed the deal last year and the plan was accelerated after his state visit to Cuba in March.
But Ouma Oluga, secretary-general of Kenya Medical Practitioners, Pharmacists and Dentists Union (KMPDU), told Reuters the decision is unethical because there are enough doctors locally.
“There are 2,000 Kenyan doctors that require employment and 170 specialists… have not been deployed by the Ministry of health,” he said. “We do not understand why a government would be creating employment for another country and not their own.”
The dispute reflects an attempt by the government to resolve the problem of inadequate healthcare provision that many medical professionals say has been left to fester by successive administrations.
Kenya’s doctor-to-patient ratio is one to 16,000, according to official data, far below a recommendation of the U.N. World Health Organization of one to 1,000.
The government says doctors in far-flung hospitals lack specialized skills, forcing patients to pay to travel to the capital Nairobi or abroad for treatment.
Doctors say they are underpaid and lack equipment. In March, four members of staff at Kenya’s largest referral hospital were suspended for starting brain surgery on the wrong patient.
Last year the government granted doctors a pay rise promised in 2013 after a three-month strike. Oluga said KMPDU will not interfere with the government plan of importing doctors.
“If the Kenyan government wants to bring Cuban doctors, that’s up to them,” he said.
The doctors are expected to arrive in June and each county should get at least two. They will work in a country where medical provision is split between central government and 47 county governments.

Imagine storing digital data in DNA, wearing a device that makes you smarter or creating new materials by manipulating the genes of microbes.
These ideas may sound like science fiction, but scientists are working on technologies that combine what they know about biology and altering it with the help of artificial intelligence. Their work was presented at the 2018 Milken Institute Global Conference during a panel called “Things That Will Blow Your Mind.”
“The machine finds stuff in biology that a human would never find,” Joshua Hoffman, co-founder and chief executive officer of Zymergen, said.
The company is conducting experiments that would never have been possible just a few years ago, Hoffman said.
Manipulating microbial genes
Zymergen uses computers to design experiments that manipulate the genes of microbes so the chemicals they produce can make stronger or better materials.
“We use automation and machine learning to engineer microbes, little single-cell creatures to turn them into the chemical factories of the future,” Hoffman said. “What we’re doing is we’re searching the genome for the things that might work. What machine learning does is it looks for patterns that a human wouldn’t find in ways that are more likely than not to have the genetic changes in the genome that are going to have the impact, the trait that we want.”
He said what takes humans years to discover, computers can do in just months. The bulk of Zymergen’s work is with the chemicals and materials industry as well as with agricultural companies.
“We can work to increase the effectiveness of crop protection agents so herbicides, fungicides, those sorts of things. We can reduce the toxicity of agents that seem to work but actually cause other kinds of problems,” Hoffman added.
Enhancing the human brain
Instead of enhancing microbes, theoretical neuroscientist Vivienne Ming spoke extensively about improving the human brain.
“What I’m interested in is cognitive prosthetics. Can I literally jam something in your brain and make you smarter?” asked Ming, who founded the think tank Socos Labs.
“How much you can think about, pay attention to, mentally operate on at any given moment – we’ve actually found that we can increase that by about 15 percent,” she said.
Laboratories around the world are already conducting research on different types of external noninvasive brain stimulation for autism, to treat depression and to improve the brain’s cognitive abilities.
Ming said one application for improving cognition is to level the playing field for underprivileged children.
“For that hour that they may be spending in a remedial class, we might actually be able to use that technology that brings them right back up with the rest of the kids,” she added.
In a world with artificial intelligence, enhancing cognition is one way for humans to compete with machines, Ming said.
“In a world of increasing technology, this is one possibly to keep us ever relevant is to find the best of who we are and combine it with the best of what we can build in a very deep and fundamental way,” she said.
DNA data storage
Inspired by biology, Hyunjun Park and his company, Catalog, make synthetic DNA used to store digital data.
“We as a society are generating so much data with 5G wireless networks, Internet of Things, high-definition video and just social media so by the year 2025, we’re going to generate a lot more data and a lot more useful data than we’ll have the capacity to store, and so we are in need of a new medium that can be much more efficient than the current solutions,” Park said.
Storage data in the cloud takes up “acres of land, cities worth of power and it costs billions of dollars to build and maintain,” he explained.
In contrast to current forms of data storage, Park said DNA can store much more information that can last thousands of years, and his company has figured out how to do it cheaper than other labs.
“It’s a liquid solution that you move around to assemble different pieces of DNA and then for storage, we will dry that down so that it’s a powder in any tube that you are storing it in,” Park said.
He said an industrial scale proof of concept for DNA storage can be ready as early as 2019.
As scientists from various subfields of biology take advantage of artificial intelligence, investors are paying attention.
“These traditional investors in the Silicon Valley area that’s been invested in tech companies, they are now looking at biotech and seeing this as really the future of innovation,” Park said.

A koala hospital and new wildlife reserves are the focus of one of Australia’s boldest plans to protect the vulnerable marsupial. Almost 25,000 hectares of state forest will be set aside for koalas in New South Wales state, which will also set up a new clinic north of Sydney to provide specialist care for sick and injured animals.
Koalas are officially listed as vulnerable to extinction in New South Wales. The state government is to spend $34 million on a range of measures to protect the iconic marsupial.Special reserves will be set up where the animals will be able to breed freely.
The koala population in New South Wales has fallen by a quarter over the past two decades. It is estimated there are 36,000 koalas left in the state.Their numbers have also fallen in other parts of Australia.
The animals face various threats, including a loss of habitat due to land-clearing, attacks by dogs, bushfires, heatwaves and road accidents. A sexually-transmitted disease — chlamydia — is also harming the health of many koalas.
Special measures will also be put in place to help drivers avoid koalas that stray onto highways, including better signs. Tunnels and specially-made bridges have also allowed wildlife to traverse roads while avoiding cars and trucks.
New South Wales environment minister Gabrielle Upton hopes to set up a network of koala and wildlife hospitals to help injured animals.
“This is so there are places that we can have resident expertise in one placein places where we know that koala populations are present and need to be sustained and therefore increased over time. We are going to trial chlamydia vaccinations. Chlamydia is a disease that impacts them most severely on the north coast in New South Wales. There are some really practical parts of this package that address some of the roadkill hot-spots,” said Upton.
“We have had some success with underpasses and overpasses in areas where they know they have core habitat. We need to ensure we have the right road signs, the right fencing.”
The new koala clinic will be set up in Port Stephens, north of Sydney. It will join an existing hospital in the regional town of Port Macquarie that began treating injured marsupials in 1973.
Conservationists have welcomed the new facility but argue that the New South Wales state government’s multi-million dollar plan does not address the number one threat to koalas – land clearing and logging.
The koala lives in trees and has large furry ears, sharp claws adapted for climbing and no tail. It features in many Aboriginal stories of creation and is considered a totemic species.

NASA is planning to send a tiny autonomous helicopter to Mars on its next rover mission to the red planet.
The space agency announced Friday that the helicopter will be carried aboard the Mars 2020 rover as a technology demonstration to test its ability to serve as a scout and to reach locations not accessible by ground.
The helicopter is being developed at NASA’s Jet Propulsion Laboratory in Southern California.
The craft weighs less than 4 pounds (1.8 kilograms), has a fuselage about the size of a softball and twin, counter-rotating blades that will spin at almost 3,000 rpm — a necessity in the thin Martian atmosphere. Solar cells will charge its lithium-ion batteries.
Flights will be programmed because the distance to Mars precludes real-time commands from Earth.

America will not be “cheated” by foreign countries that “extort” unreasonably low drug prices from U.S. companies, declared President Donald Trump on Friday.
Rolling out an ambitious blueprint to significantly cut the cost of prescription medication here and abroad, Trump announced he is directing U.S. Trade Representative Robert Lighthizer to make it a priority to prevent foreign countries from forcing American drugmakers to provide medicines at drastically lower prices than in the United States.
“It’s time to end the global freeloading once and for all,” Trump said during a White House Rose Garden event.
Trump did not specifically name any countries, but according to a report from the White House Council of Economic Advisers profit margins on brand-name drugs in the United States are four times as high as in more regulated markets, such as major European countries and Japan.
Earning more profit in such countries presumably would give drugmakers greater maneuverability with their bottom line to charge less in America.
In its annual report last month on the protection of intellectual property around the world, the Office of the U.S. Trade Representative, in addition to EU nations and Japan, also specifically criticized the drug pricing and reimbursement policies of Canada, India, South Korea and New Zealand.
In his Rose Garden comments, Trump also singled out what he called greedy companies and middlemen, who he declared had grown rich through “dishonest double-dealing,” vowing his administration is now “putting American patients first.”
Trump’s plan has four main themes: increasing marketplace competition; empowering private health care plans to negotiate discounts for Medicare beneficiaries; providing new incentives for manufacturers to reduce the list prices of medications; and reducing out-of-pocket costs for patients.
The president’s plan, however, breaks with one of his campaign promises, which was to authorize the purchasing clout of the federal government to negotiate directly with drug manufacturers for lower prices.
“Instead of putting forth a bold initiative, the president pulled his punch,” said Nancy Pelosi, the leader of the opposition Democrats in the House of Representatives. “The president is breaking his promise to the American people to allow Medicare to negotiate lower drug prices, which would save seniors billions of dollars at the pharmacy.”
Medicare is a federal health insurance program, covering 15 percent of the U.S. population, primarily those age 65 and older and certain younger people with disabilities.
Pelosi is calling on Trump to work “with Democrats to offer real solutions for struggling families, not waste their time bragging about meager, window dressing (a superficial appearance) policies.”
Shortly after the Rose Garden event, Health and Human Services Secretary Alex Azar told reporters in the briefing room that much of Trump’s plan can be achieved without legislative action.
“Most of this can be done by executive action,” Azar said, adding that “some of this will require regulatory action” that would take months, while restructuring the entire U.S. drug system would take years.
Azar, a former chief executive of the giant Eli Lilly pharmaceutical company, where he raised drug prices, explained incentives need to be put into place to encourage the lowering of prices.
“The entire system is actually built for increased prices and high prices,” he explained.
The Pharmaceutical Research and Manufacturers of America (PhRMA), which is the industry’s main lobbying organization, said some of Trump’s proposals could help make medicines more affordable for patients, but “others would disrupt coverage and limit patients’ access to innovative treatments.”
PhRMA President and Chief Executive Officer Stephen Ubl said in a statement the association “will be reviewing the request for information and look forward to participating in the comment process in the coming months.”

An updated version of the SpaceX Falcon 9 rocket, tailored for eventual crewed missions into orbit, made its debut launch Friday from Florida’s Cape Canaveral, carrying a communications satellite for Bangladesh.
The newly minted Block-5 edition of the Falcon 9 — equipped with about 100 upgrades for greater power, safety and reusability than its Block-4 predecessor — lifted off at 4:14 p.m. EDT (2014 GMT) from the Kennedy Space Center.
Minutes later, the Block-5’s main-stage booster flew itself back to Earth to achieve a safe return landing on an unmanned platform vessel floating in the Pacific Ocean.
The recoverable booster for the Block-5 is designed to be reused at least 10 times with minimal refurbishment between flights, allowing more frequent launches at lower cost — a key to the SpaceX business model.
Enhanced rocket reusability also is a core tenet of SpaceX owner and billionaire entrepreneur Elon Musk’s broader objectives: making space travel commonplace and ultimately sending humans to Mars.
The flight came a day after the original launch countdown was halted one minute before blastoff time due to a technical problem detected by the rocket’s onboard computers. Friday’s second attempt by SpaceX, formally known as Space Exploration Technologies, appeared to have gone off without a hitch.

On Yaji Mountain in southern China, they are checking in the sows a thousand head per floor in high-rise “hog hotels.”
Privately owned agricultural company Guangxi Yangxiang Co Ltd is running two seven-floor sow breeding operations, and is putting up four more, including one with as many as 13 floors that will be the world’s tallest building of its kind.
Hog farms of two or three floors have been tried in Europe.
Some are still operating, others have been abandoned, but few new ones have been built in recent years, because of management difficulties and public resistance to large, intensive farms.
Now, as China pushes ahead with industrialization of the world’s largest hog herd, part of a 30-year effort to modernize its farm sector and create wealth in rural areas, companies are experimenting with high-rise housing for pigs despite the costs.
The “hotels” show how far some breeders are willing to go as China overhauls its farming model.
“There are big advantages to a high-rise building,” said Xu Jiajing, manager of Yangxiang’s mountain-top farm.
“It saves energy and resources. The land area is not that much but you can raise a lot of pigs.”
Companies like Yangxiang are pumping more money into the buildings — about 30 percent more than on single-story modern farms — even as hog prices in China hold at an eight-year low.
For some, the investments are too risky. Besides low prices that have smaller operations culling sows or rethinking expansion plans, there is worry about diseases spreading through such intensive operations.
But success for high-rise pig farms in China could have implications across densely populated, land-scarce Asia, as well as for equipment suppliers.
“We see an increasing demand for two- or three-level buildings,” said Peter van Issum, managing director of Microfan, a Dutch supplier that designed Yangxiang’s ventilation system.
Microfan also supplied a three-story breeding operation, Daedeok JongDon GGP Farm, in South Korea.
“The higher ones are still an exception, but the future might change rapidly,” van Issum said.
High-rise hogs
Yaji Mountain seems an unlikely location for a huge breeding farm. Up a narrow road, away from villages, massive concrete pig buildings overlook a valley of dense forest that Yangxiang plans to develop as a tourist attraction.
The site, however, is relatively close to Guigang, a city with a river port and waterway connections to the Pearl River Delta, one of the world’s most densely populated regions.
While Beijing is encouraging more livestock production in China’s grain basket in the northeast, many worry that farms there will struggle to get fresh pork safely to big cities thousands of miles away.
That has helped push some farm investments to southern provinces like Guangxi and Fujian, where land is hilly but much closer to many of China’s biggest cities.
Yangxiang will house 30,000 sows on its 11-hectare site by year-end, producing as many as 840,000 piglets annually. That will likely make it the biggest, most-intensive breeding farm globally. A more typical large breeding farm in northern China would have 8,000 sows on around 13 hectares.
In Fujian province, Shenzhen Jinxinnong Technology Co Ltd also plans to invest 150 million yuan ($24 million) in two five-story sow farms in Nanping. Two other companies are building high-rise hog farms in Fujian as well, according to an equipment firm involved in the projects.
Thai livestock-to-retail conglomerate CP Foods is also building four six-story pig units with local firm Zhejiang Huatong Meat Products Co in Yiwu, a Chinese city near the large populations around Shanghai.
High-tech complexity
Yangxiang spent 16,000 yuan per sow on its new farm, about 500 million yuan total, not including the cost of the pigs.
Building upward means higher costs and greater complexity, such as for piping feed into buildings, said Xue Shiwei, vice chief operations officer at Pipestone Livestock Technology Consultancy, a Chinese unit of a U.S. farm management company.
“It would save on land but increase the complexity of the structure, and costs for concrete or steel would be higher,” he said.
Health concerns also raise costs, because the risk of rampant disease — an ever-present problem in China’s livestock sector — is higher with more animals under one roof.
Even two-story farms in Europe have sparked worries that pigs will receive less care, said Irene Camerlink, an animal welfare expert at the University of Veterinary Medicine in Vienna who has worked with Chinese farms.
Any outbreak of disease could lead to extensive culling, she said.
Farm manager Xu said Yangxiang reduces the risk of disease by managing each floor separately, with staff working on the same floor every day. New sows are introduced to a building on the top floor, and are then moved by elevator to an assigned level, where they remain.
The ventilation system is designed to prevent air from circulating between floors or to other buildings. Air enters through ground channels and passes through ventilation ducts on each level. The ducts are connected to a central exhaust on the roof, with powerful extraction fans pulling the air through filters and pushing it out of 15-meter high chimneys.
A waste treatment plant is still under construction on Yaji Mountain to handle the site’s manure. After treatment, the liquid will be sprayed on the surrounding forest, and solids sold to nearby farms as organic fertilizer.
The project’s additional equipment — much of it imported — to reduce disease, environmental impact and labor costs, significantly increased Yangxiang’s spending, the company said.
But after testing other models, Yangxiang concluded the multistory building was best. Others are less convinced.
“We need time to see if this model is do-able,” said Xue of the farm management firm, adding that he would not encourage clients to opt for “hog hotels.”
“There will be many new, competing ideas [about how to raise pigs in China],” Xue said, including high-rise farms. Eventually, “a suitable model will emerge.”

Before taking office, President Donald Trump railed against the pharmaceutical industry and accused it of “getting away with murder.”
The populist rhetoric appears to be giving way to a more nuanced strategy focused on making the pharmaceutical market more open and competitive, with the aim of lowering costs for consumers.
It’s an approach that could avoid a direct confrontation with the powerful pharmaceutical lobby, but it could also underwhelm Americans seeking relief from escalating prescription costs.
On Friday, Trump is scheduled to give his first speech on an overarching plan to lower drug prices. Administration officials previewing the speech Thursday touted it as the most comprehensive plan to tackle prescription drug costs that any president has ever proposed, but offered few specifics.
Officials said the plan would increase competition, create incentives for drugmakers to lower initial prices and slash federal rules that make it harder for private insurers to negotiate lower prices. The result would be lower pharmacy costs for patients — a key Trump campaign promise.
The plan will not include giving the federal Medicare program power to directly negotiate prices with drugmakers, they noted. Trump campaigned on the idea, which is vigorously opposed by the pharmaceutical industry.
Public outrage over drug costs has been growing for years, because Americans are being squeezed in a number of ways: New medicines for cancer and other life-threatening diseases often launch with prices exceeding $100,000 per year. Drugs for common ailments like diabetes and asthma routinely see price hikes around 10 percent annually. Meanwhile some companies have been buying up once-cheap older drugs and hiking prices by 1,000 percent or more.
Since entering the White House, Trump has backed away from reforms directly targeting drugmakers and staffed his administration with appointees who have deep ties to the industry, including his health secretary, Alex Azar, a former top executive at Eli Lilly.
Still, administration officials ratcheted up the rhetoric ahead of Trump’s speech. Azar promised bold action. FDA Commissioner Scott Gottlieb — another Trump appointee with industry connections — hinted at a plan to “dismantle” the convoluted system of discounts and rebates between drugmakers and health care middlemen.
On Thursday, administration officials also vowed to address foreign governments that rely on U.S. medicines but pay drastically lower prices due to government controls. The U.S. accounts for 70 percent of the world’s brand-name drug profits, according to a White House report released earlier this year.
Here are some of the drivers of U.S. prescription drug prices, proposals for reducing the costs and what’s at stake:
Lack of regulation
Drugmakers generally can charge as much as the market will bear because the U.S. government doesn’t regulate medicine prices, unlike most other countries.
Medicare is the largest purchaser of prescription drugs in the nation, covering 60 million seniors and Americans with disabilities, but it is barred by law from directly negotiating lower prices with drugmakers. Democrats have long favored giving Medicare that power, but Republicans traditionally oppose the idea.
The powerful pharmaceutical lobby has repeatedly fended off proposals that could lower prices, such as Medicare negotiations or importing drugs from countries that regulate pricing.
With no direct government price regulation, the primary check on prices comes from buyers in bulk — such as insurance companies and pharmacy benefit managers, which handle prescription coverage for insurers, employers and other big clients.
But because there are so many players in the fragmented system, the discounts achieved in the U.S. are generally far more modest than those in other countries.
The result is that the U.S. spends more on medicines than any other nation. In 2015, the U.S. spent $1,162 per person on pharmaceuticals, according to the Organization for Economic Cooperation and Development. That compares with $756 for Canada and $497 for the United Kingdom, both of which have government measures to control drug prices.
Lack of transparency
The U.S. system for pricing drugs is notoriously complex, so much that the “real” price for most medicines isn’t clear. Critics contend that this lack of transparency limits competition and drives prices higher.
Pharmaceutical companies often launch their drugs with high initial prices. But they argue list prices are merely a starting point for negotiations because they give substantial rebates and discounts to pharmacy benefit managers. Those price concessions are almost never disclosed and it’s unclear what portion actually flows back to consumers.
FDA Commissioner Scott Gottlieb and others say the lack of transparency in the current system creates perverse incentives in which drugmakers and other health care companies benefit from rising prices — at the expense of patients.
Trump officials have suggested requiring Medicare pharmacy benefit managers to share rebate payments with patients. Another proposal would do away with rebates altogether to encourage more upfront discounts in Medicare.
But the benefit managers and insurers say that they use rebates to lower health care premiums overall and that doing away with them would drive up costs.
Patents and anti-competitive tactics
Patents last longer in the U.S. than most countries, typically giving companies a dozen years of competition-free marketing after a drug launches. Most drugmakers increase their prices annually during this monopoly period, and until recently double-digit price hikes were the norm.
Drugmakers also have developed a number of techniques to block competitors from launching lower-cost generic drugs. Companies often tweak drug formulations to extend their patents. In other cases, companies directly pay would-be competitors to stay off the market in so-called “pay-to-delay” deals.
Gottlieb has promised a crackdown on some of these techniques used to “game the system.” He’s highlighted a practice in which drugmakers use tightly controlled distribution systems to prevent rival manufacturers from purchasing their drug. This effectively blocks the development of generic versions because generic drugmakers must test their products against the original medicine before they can win FDA approval.
Public perception
A majority of Americans say bringing down prescription drug prices should be a “top priority” for Trump and Congress, according to recent polling by the Kaiser Family Foundation.
And experts who study drug pricing say it’s encouraging that the discussion around the issue has moved from outrage to sophisticated reforms. But some warn there is no guarantee that unraveling the current pricing-setting bureaucracy will lead to lower prices, because it all starts with drugmakers’ prices.
“Until we get closer to policy solutions that address the ability of drug manufacturers to set whatever price they want and increase prices year after year we may only be scratching the surface of this problem,” said Juliette Cubanski, a health care expert with the nonpartisan Kaiser Family Foundation.
Dan Mendelson, a health care consultant, said: “If they don’t address the cost that patients see at the pharmacy counter it’s not going to be seen as responsive.”
The World Health Organization said Friday it is preparing for “the worst case scenario” for an Ebola outbreak in the Democratic Republic of Congo.
WHO said Thursday that between April 4 and May 5, twenty-seven cases of fever with hemorrhagic signs, including 17 deaths, were reported in the DRC’s Bikoro district. WHO says two of the cases tested positive for the Ebola virus.
The DRC Ministry of Public Health has requested WHO’s support in coordinating the international and NGO response to the health crisis.
The full extent of the outbreak is not yet known, according to WHO, and the location presents “significant logistical challenges.” The affected area is remote with limited communication and poor transportation infrastructure.
Ebola, named for the Congolese river near where it was first identified in 1976, begins with a sudden fever, aching muscles, diarrhea and vomiting. It is a hemorrhagic fever, marked by spontaneous bleeding from internal organs and, in most cases, death. It can be transmitted by close contact with infected animals or people, usually through blood or other bodily fluids.
People can contract the virus through direct contact with victims’ bodies at funerals. Caretakers, nurses and doctors treating Ebola patients also are at high risk.
WHO says the outbreak in Bikoro is the ninth outbreak of Ebola in the DRC since it first emerged in 1976.

Two weeks of climate talks organized by the United Nations ended Thursday as countries failed to resolve differences about implementing the Paris climate accord.
The negotiations will resume in Bangkok in September, where an extra week’s meeting has now been scheduled.
The pact’s 197 signatories have set a December deadline to agree on the precise rules that countries have to stick to under the Paris agreement.
The lack of progress threatens to unravel three years’ worth of work to complete the Paris agreement, a landmark deal reached in 2015 that set a goal to limit fossil-fuel pollution in all nations for the first time and keep global warming below 2 degrees Celsius by the end of the century.
Overall progress at the meeting in Bonn was very slow, with some countries such as China looking to renegotiate aspects of the Paris deal.
Patricia Espinosa, head of the U.N. agency that oversees climate talks, described the package being negotiated as “highly technical and complex.” It aims to ensure that the efforts countries claim they’re making in the fight against global warming can be verified and compared.
The administration of President Barack Obama was widely credited with helping to bring together the diverging interests of rich and poor countries in the drive to secure the Paris deal. His successor, President Donald Trump, withdrew the U.S. from the accord in June 2017. His administration has attacked climate science, saying it questions whether human activity is behind climate change, and is focused on boosting the fossil fuel industry.

Young men who smoke are more likely to have a stroke before age 50 than their peers who avoid tobacco, a small study suggests.
Smoking has long been linked to an increased risk of stroke in older adults, but research to date examining this connection in younger adults has mainly focused on women. For the current study, researchers examined data on 615 men who had a stroke before age 50 and compared their smoking habits to a control group of 530 similar men who didn’t have a history of stroke.
Overall, current smokers were 88 percent more likely to have a stroke than men who never smoked, the study found.
Light smokers who had fewer than 11 cigarettes a day were 46 percent more likely to have a stroke. Heavy smokers with a two pack-a-day habit, or more, were over five times more likely to have a stroke.
‘Simple takeaway’
“The simple takeaway is the more you smoke, the more you stroke,” said lead study author Janina Markidan of the University of Maryland School of Medicine in Baltimore.
Smoking causes inflammation in blood vessels that increases the risk of blood clots forming, which in turn increases the risk of stroke, Markidan said by email.
“Although reducing the number of cigarettes smoked can reduce your risk of stroke, quitting is still the best choice for smokers,” Markidan added.
For the study, researchers focused on what’s known as an ischemic stroke, the most common kind, which occurs when a clot blocks an artery carrying blood to the brain.
Study has limitations
Among the stroke cases included in the study, 239 men had never smoked and 108 were former smokers. Another 103 men smoked less than 11 cigarettes daily, while 97 men smoked between 11 and 20 cigarettes a day and 40 men smoked 21 to 39 cigarettes daily.
An additional 28 men who had strokes smoked more than 40 cigarettes, or two packs, a day.
Most of the men who had strokes in the study were between 35 and 49 years old.
The study wasn’t a controlled experiment designed to prove whether or how smoking habits might directly influence the potential for a stroke in younger men.
Another limitation is that researchers lacked data on other tobacco products participants used in addition to cigarettes, which might influence their risk of stroke, researchers note in the journal Stroke.
Results hold true for younger smokers
The study team also lacked data on other factors that can independently influence the risk of stroke such as alcohol consumption or exercise habits.
Even so, the results suggest the link between smoking and strokes that is well established for older adults also holds true for younger smokers, said Allan Hackshaw, a researcher at University College London in the UK, who wasn’t involved in the study.
“It shows that smoking has a serious impact even when people are younger,” Hackshaw said by email. “Because treatments for stroke are much better now (fewer die from it straight away), many people who suffer one can have long-lasting consequences and physical disabilities at an age when they are usually expected to be working and physically active/fit.”

There’s a budding industry that’s trying to solve the problem of the limp lettuce and tasteless tomatoes in America’s supermarkets.
It’s full of technologists who grow crops in buildings instead of outdoors, short-cutting the need to prematurely harvest produce for a bumpy ride often thousands of miles to consumers in colder climes.
More than 30 high-tech companies from the U.S. to Singapore hoping to turn indoor farming into a major future food source, if only they can clear a stubborn hurdle: high costs.
These companies stack plants inside climate-controlled rooms, parse out nutrients and water, and bathe them with specialized light. It’s all so consumers can enjoy tasty vegetables year-round using a fraction of the water and land that traditional farming requires. Farmers can even brag the produce is locally grown.
But real estate around cities is pricey. Electricity and labor don’t come cheap. And unlike specialty crops like newly legal marijuana, veggies rarely command premium prices. (It’s tough to compete with plants grown in dirt with free sunlight, after all.)
Even the best-funded indoor farming company on the planet — Plenty, which has raised nearly $230 million so far — has embraced a longtime farmers’ crutch: government handouts. It hasn’t found any takers yet.
“We believe society should consider investing in this new form of agriculture in the way it invested in agriculture in the 1940s,” said Plenty CEO Matt Barnard in a recent interview.
Barnard says public aid — in the form of cheaper power — is one way to turn a good but elusive idea into a sustainable venture.
Last year, the U.S. paid farmers $9.3 billion in direct support, and subsidized weather-related crop insurance to the tune of $5.1 billion. In a nutshell, Barnard argues that some of that money could be diverted to crops that grow in rain or shine.
Plenty grows kale, mixed greens, basil and natural sweetener stevia in a grey, low-rise warehouse complex in the industrial suburb of South San Francisco.
Visitors arriving via the back door must don full-body overalls and rubber boots dipped in disinfecting shoe baths before entering the air-tight workspace.
Seedlings are grown on flatbeds and bathed in purple light that gives them the look of a 3D movie watched without glasses. Maturing plants are stuffed into columns where they grow sideways, fed by drip irrigation, and irradiated by columns of light-emitting diodes.
The plants will be clipped and packaged before heading to stores later this year.
But there are some noticeable gaps in the menu. There are no carrots or tomatoes, because long roots that grow down and vines that require human pruning don’t do well on walls.
For indoor farms, making money has largely meant shipping in bulk to grocery stores, a conundrum if costs aren’t in line.
Investment in indoor farming soared to $271 million last year, up from just $36 million in 2016, according to market research firm Cleantech Group.
“The question is, how are they going to scale?” asks Pawel Hardej, CEO of Civic Farms, a vertical farming consultancy in Austin, Texas.
There have been plenty of indoor farming failures already.
FarmedHere shuttered its operations in Louisville, Kentucky, and Bedford Park, Illinois, in January last year due to cost overruns.
Georgia-based PodPonics, which filed for bankruptcy in 2016, cited labor costs as its biggest drag.
Google’s X, the search giant’s secretive “moonshot factory,” killed its indoor farming efforts because it couldn’t grow food staples like grains and rice.
Even fans of the technology aren’t sure it can beat another sheltered alternative: greenhouses.
“Vertical farming to a lot of [investors] is an ‘if’ and a ‘maybe’ versus a ‘when,'” says Cleantech adviser Yoachim Haynes. “The question that needs to be answered is, ‘Can they do it with cheaper electricity and cheaper labor?’ This is not a question that many have been able to answer.”
Barnard says Plenty can prosper if it spends 3 to 5 cents per kilowatt hour on power — well below the 10.4 cents that is the average price nationwide, according to the U.S. Energy Information Administration.
While Plenty announced plans to build a 100,000 square-foot facility in the Seattle suburb of Kent in November, it said it isn’t in talks about power breaks with any U.S. city now.
Most public support has so far been in rebates for energy-efficient lighting, not running costs.
Seattle City Light provided $10,000 worth of energy-efficient lighting to an indoor growing facility that helped feed the city’s homeless. But it already offers the lowest power rate of the top 25 cities in America. “That’s the deal that’s on the table,” says spokesman Scott Thomsen.
Chicago provided some $344,000 in construction grants since 2008 to The Plant , a former pork processing plant that is home to multiple indoor farms.
While that helped with structural improvements, it didn’t help with operations, says John Edel, the president of Bubbly Dynamics LLC, which owns The Plant.
Supplying grocery stores in large volumes is “harder than it sounds,” he says. And other ways of obtaining cheap power — like The Plant’s plan to install a bio-gas guzzling turbine — have faced obstacles that make it uneconomical.
“There isn’t a whole lot in the way of incentives for farms here,” Edel says. “There needs to be.”

Health officials in the Democratic Republic of Congo are racing to contain a new Ebola outbreak announced this week. At least two people are confirmed to have died of Ebola this month in a remote village of northwest DRC, very close to the border of the smaller, neighboring Republic of Congo.
The DRC’s health minister, Dr. Oly Ilunga, has been keeping people updated on social media, tweeting that on Thursday — some 24 hours after the initial announcement — a team of 12 experts landed in Mbandaka, the city closest to the outbreak.
Ilunga said that Ebola had been confirmed in two of 17 hemorrhagic fever deaths seen in recent weeks in the northwest village of Bikoro. The area has reported 21 cases of hemorrhagic fever in all.
“Our country,” he said in an open letter to the Congolese population, “is facing a new epidemic of Ebola that is a public health emergency of international concern.”
The World Health Organization has released $1 million from its emergency fund to respond to this outbreak. WHO and medical aid group Doctors Without Borders are leading the response, and have sent experts to the site.
“MSF’s DRC emergency team is already on site and has been supporting the Ministry of Health to deploy a rapid and tailored response to the emergency since last Saturday,” the group, known by its french acronym MSF, said in a statement. “MSF will continue to adapt its response according to the needs on the ground.”
The aid group declined to give more details, saying its experts were still gathering information.
‘This is not the first time’
This is not Congo’s first encounter with the hemorrhagic fever, which causes an acute, serious illness which is often fatal if left untreated. It is transmitted to people from wild animals and can be spread through human-to-human transmission.
Ebola derives its name from the place it was first discovered, the Ebola River, a tributary of the Congo River, in 1976. The average survival rate is 50 percent, according to the WHO.
WHO spokesman Tarik Jasarevic told VOA this is Congo’s ninth outbreak of Ebola since the virus was first identified, including one last year that he said “was contained relatively quickly.”
“So we are hoping to do the same thing this time around — to send quickly teams to the area where the virus has been confirmed to be circulating, to be in position to identify those who are sick, to be in position to identify those who have been potentially exposed, to put in place all those necessary measures that are used every time when there is an Ebola outbreak to try to stop the transmission as fast as possible,” he said.
This latest outbreak has occurred in an area near the banks of the Congo River, just across the border from the Republic of Congo. Because this region is poor in infrastructure, its many waterways are vital for transport and trade activities.
Ebola killed more than 11,000 people in a two-year epidemic that ravaged Guinea, Sierra Leone and Liberia between 2014 and 2016. So far, none of the recent outbreaks in Congo have been connected to that event.
The WHO’s Jasarevic said that to contain the newest outbreak, it is crucial that people in and around Bikoro cooperate with local health authorities.
“It is really important that communities in this particular area are engaged, are working together with authorities in terms of safe burial practices, in terms of proper contact tracing, to be compliant with those procedures,” he said. “The community engagement has been proven as a key component in successful containment of an Ebola outbreak.”
