True north isn’t quite where it used to be.

Earth’s north magnetic pole has been drifting so fast in the last few decades that scientists that past estimates are no longer accurate enough for precise navigation. On Monday, they released an update of where true north really was, nearly a year ahead of schedule.

The magnetic north pole is wandering about 34 miles (55 kilometers) a year. It crossed the international date line in 2017, and is leaving the Canadian Arctic on its way to Siberia.

The constant shift is a problem for compasses in smartphones and some consumer electronics. Airplanes and boats also rely on magnetic north, usually as backup navigation, said University of Colorado geophysicist Arnaud Chulliat, lead author of the newly issued World Magnetic Model. GPS isn’t affected because it’s satellite-based.

Magnetic north has military uses

The military depends on where magnetic north is for navigation and parachute drops, while NASA, the Federal Aviation Administration and U.S. Forest Service also use it. Airport runway names are based on their direction toward magnetic north and their names change when the poles moved. For example, the airport in Fairbanks, Alaska, renamed a runway 1L-19R to 2L-20R in 2009.

The U.S. National Oceanic and Atmospheric Administration and United Kingdom tend to update the location of the magnetic north pole every five years in December, but this update came early because of the pole’s faster movement.

The movement of the magnetic north pole “is pretty fast,” Chulliat said. 

Pole’s pace has increased

Since 1831 when it was first measured in the Canadian Arctic it has moved about 1,400 miles (2,300 kilometers) toward Siberia. Its speed jumped from about 9 mph (15 kph) to 34 mph (55 kph) since 2000. 

The reason is turbulence in Earth’s liquid outer core. There is a hot liquid ocean of iron and nickel in the planet’s core where the motion generates an electric field, said University of Maryland geophysicist Daniel Lathrop, who wasn’t part of the team monitoring the magnetic north pole.

“It has changes akin to weather,” Lathrop said. “We might just call it magnetic weather.”

The magnetic south pole is moving far slower than the north. 

In general Earth’s magnetic field is getting weaker, leading scientists to say that it will eventually flip, where north and south pole changes polarity, like a bar magnet flipping over. It has happened numerous times in Earth’s past, but not in the last 780,000 years. 

“It’s not a question of if it’s going to reverse, the question is when it’s going to reverse,” Lathrop said.

Flip will take time

When it reverses, it won’t be like a coin flip, but take 1,000 or more years, experts said. 

Lathrop sees a flip coming sooner rather than later because of the weakened magnetic field and an area over the South Atlantic has already reversed beneath Earth’s surface.

That could bother some birds that use magnetic fields to navigate. And an overall weakening of the magnetic field isn’t good for people and especially satellites and astronauts. The magnetic field shields Earth from some dangerous radiation, Lathrop said.

Arctic islands north of Norway are warming faster than almost anywhere on Earth and more avalanches, rain and mud may cause “devastating” changes by 2100, a Norwegian report said on Monday.

The thaw on the remote Svalbard islands, home to 2,300 people and where the main village of Longyearbyen is 1,300 kms (800 miles) from the North Pole, highlights risks in other parts of the Arctic from Alaska to Siberia.

Average temperatures on Svalbard have leapt between three and five degrees Celsius (5.4-9.0 Fahrenheit) since the early 1970s and could rise by a total of 10C (18F) by 2100 if world greenhouse gas emissions keep climbing, the study said.

Almost 200 governments promised in the 2015 Paris climate agreement to limit a rise in average global temperatures to “well below” 2C (3.6F) above pre-industrial times by 2100. Worldwide, temperatures are up about 1C (1.8F).

On Svalbard, the envisaged rise in temperatures would thaw the frozen ground underpinning many buildings, roads and airports, cause more avalanches, “slushflows” and landslides, melt glaciers and threaten wildlife such as polar bears and seals that rely on sea ice to hunt.

“A 10 degree warming, with the implications for Arctic nature, ice-dependent species, will be devastating,” Climate and Environment Minister Ola Elvestuen told Reuters.

Norway will have to increase investment to relocate buildings from avalanche paths and drill deeper infrastructure foundations as permafrost thaws, the report said.

Two people died in 2015 when an avalanche destroyed 10 houses in Longyearbyen.

Many other parts of the Arctic, especially its islands, are also warming far quicker than the world average as the retreat of snow and sea ice exposes darker water and ground that soaks up ever more of the sun’s heat.

Temperatures on Svalbard would stay around current levels only if governments make unprecedented cuts in global emissions, the report said. Not enough

“No one is doing enough” to limit greenhouse gas emissions, Elvestuen said of government actions. “We have to do more … The use of oil and gas has to go down.” Norway is western Europe’s biggest oil and gas exporter.

Inger Hanssen-Bauer, head of the Norwegian Centre for Climate Services, which produced the report, said the findings were a warning for the rest of the Arctic.

“The main message is that these changes are happening so fast,” she told Reuters.

Ketil Isaksen, a lead author at the Norwegian Meteorological Institute, urged researchers to pay more attention to landslides as the permafrost melts. “There is now a lot of focus on snow avalanches, but landslides in summer should be taken more into account,” he said.

Researchers and doctors are using incredibly tiny particles — fluorescent nanoparticles — in a quest for new ways to fight cancer. Some nanoparticles, just billionths of a meter across, are engineered to carry special dye that glows when it hits cancer cells. Oregon State University scientists say this makes it easier for surgeons to find and remove tumors. Iryna Matviichuk visited Portland and learned the new procedure is closer to testing in human patients. Anna Rice narrates her report.

In advance of World Cancer Day (February 4), the World Health Organization is issuing new cancer pain control guidelines aimed at ending the needless suffering experienced by millions of people afflicted with this illness. 

Cancer is a leading cause of death globally.  The World Health Organization reports there are more than 18 million new cases every year and 9.6 million deaths, most in low-or middle-income countries.

Great advances have been made in the treatment of cancer, but measures to relieve the horrific pain experienced by patients lag woefully behind.  WHO hopes to remedy this with its new guidance on pain management.

Director of WHO’s Department for the Management of Noncommunicable Diseases, Etienne Krug, says controlling pain should be an essential part of cancer treatment.  Yet, he says pain is very often neglected as part of that treatment, a situation he considers unacceptable.

“Nobody, cancer patients or not cancer patients should live or die in pain in the 21st century.  We have the knowledge of how to treat pain,” said Krug. “We have the medicines of how to address it.  It is a question of making sure everybody has that knowledge and everybody has access to the necessary treatment.” 

Krug says the situation is most acute in the poorer countries because pain management systems tend not to be in place.  But he notes even in the rich countries people are still living and dying in pain.

WHO says opioid painkillers like oral morphine are an essential treatment for moderate to severe cancer pain.  But WHO Noncommunicable Coordinator, Cheriana Varghese says some governments have enacted regulatory and legal barriers against their use in reaction to the global scare of opioid and morphine addiction.

“When a government of a country wants to introduce opioids, there is always this looming danger that this is going to get out of hand,” Varghese said. “And, so the governments are more conservative because of this.”

Varghese says there are sufficient safeguards against the abuse of opioids and morphine.   He says these painkillers should be given only by trained health care providers, doctors and nurses.  He adds oral preparation should be given whenever possible to prevent addiction.

The Trump administration’s top health official asked Congress on Friday to pass its new prescription drug discount plan and provide it to all patients, not just those covered by government programs like Medicare.

The plan would take now-hidden rebates among industry players like drug companies and insurers and channel them directly to consumers when they go to pay for their medications. 

Patients with high drug copays stand to benefit from the proposal, while people who take no prescription drugs, or who rely on generics mainly, would probably pay somewhat more, since premiums are expected to rise.

A day after unveiling the plan as a proposed regulation, Health and Human Services Secretary Alex Azar raised the stakes by calling on Congress to make it law and broaden it to include people covered by employer health insurance, not just Medicare and Medicaid beneficiaries.

“Congress has an opportunity to follow through on their calls for transparency … by passing our proposal into law immediately and extending it into the commercial drug market,” Azar said in a speech at the Bipartisan Policy Center think tank.

Trump under pressure

Ahead of next week’s State of the Union speech, President Donald Trump is under political pressure to show results for his promise to slash prescription drug costs. Data show that prices for brand-name drugs have continued to rise, though at a somewhat slower pace. Polls show consumers across the political spectrum want government action.

Democrats say the administration’s plan doesn’t go far enough because it still leaves drug companies free to set high list prices. They say drug pricing is like a black box, and it’s impossible to tell if prices reflect actual costs or if companies are charging what they think the market will bear.

House Speaker Nancy Pelosi, D-Calif., says she’s also worried that the plan would raise premiums. HHS acknowledges Medicare prescription premiums would go up $3 to $5 a month.

Proposal draws interest

Nonetheless, the administration’s proposal appears to be in the mix as Congress gears up to craft legislation addressing prescription drug costs. Friday evening, the Republican chairman of the Senate Health, Education, Labor and Pensions Committee, expressed his support. Rebates “ought to lower costs to patients, and this is a good first step towards that goal,” Sen. Lamar Alexander, R-Tenn., said in a statement.

The complex plan would work by doing away with an exemption from federal anti-kickback rules that currently allows drugmakers, insurers and middlemen called pharmacy benefit managers to negotiate rebates among themselves.

Drug companies pay rebates to make sure their medications are covered by insurance plans that are the intermediaries between them and patients. HHS says hidden rebates can amount to up to 30 percent of a drug’s list price. Insurers say they use the money from rebates to hold down premiums for all consumers.

Under the plan, the current anti-kickback exemption for industry rebates would be replaced with a new one for discounts offered directly to consumers. 

Azar said the idea would reshape the drug pricing system, shifting it away from hidden rebates to upfront discounts, creating pressure on drugmakers to keep prices down. The proposal was co-authored with the HHS inspector general’s office.

Potential consequences

Experts say it will take time to sort out all the potential consequences.

Peter Bach, director of the Center for Health Policy and Outcomes at New York’s Memorial Sloan Kettering Cancer Center, said the current system of rebates harms patients who take costly drugs with high copays. 

Think people with cancer, patients with intractable illnesses such as multiple sclerosis or rheumatoid arthritis, and those who take brand-name medicines with no generic competition. Patients’ cost sharing is often based on list prices, not the cost of the drug after rebates.

“Simply put, those on no medications at all will just see their premiums go up and see no savings because they don’t take any medicine,” said Bach. “Those on generics only may be essentially in this category (as well). 

“But those on expensive medications … they will see savings in total,” he added. More than half a million people filled at least $50,000 in prescriptions in 2014, according to an Express Scripts report. 

Insurers and pharmacy benefit managers like Express Scripts and CVS oppose the administration plan, saying it will undercut their ability to bargain with drugmakers for lower prices. 

Companies please with plan

Drugmakers have applauded the administration’s action. 

Consumers are worried about prices for brand-name drugs, particularly new medications that promise breakthrough results. Generics account for nearly 90 percent of prescriptions filled, but brand-name drugs account for more than 70 percent of the spending.

Azar contends that under the current system everybody but the patient benefits from high prices. A high list price makes room for bigger negotiated rebates for insurers and middlemen. And drugmakers then merely build that expectation into their prices.

Before joining the Trump administration, Azar was a top executive for drugmaker Eli Lilly. That led to criticism that he would be an industry pawn. But the drugmakers vehemently disagree with some of his other ideas, including an experiment using lower international drug prices to cut some Medicare costs.

Six months after the outbreak of Ebola was declared in the Democratic Republic of Congo’s North Kivu province, the World Health Organization is expressing cautious optimism that it is making headway in controlling the spread of the deadly virus.  

Latest figures reported by the WHO show 752 cases of Ebola, including 465 deaths.

WHO Regional Director for Africa, Matshidiso Moeti, says progress in containing the spread of the virus is due to a number of public health measures, including the training of health workers on infection prevention and control, closer engagement with communities, case investigation and contact tracing.  

She says the use of a vaccine and promising new drugs have been a boon to these efforts.

“I feel optimistic,” Moeti said. “I am very clear that we need to continue this work. We need to make sure that in the places where we have made progress, we build on this progress and we do not go back. And, we are being very, very conscious of the fact that we need to invest to improve the preparedness both in the DRC areas that are highest at risk and, most importantly, in the surrounding countries that are at risk.”  

The risk of the virus spreading to countries like Uganda, Rwanda and South Sudan is very high because of the heavy cross-border traffic among the countries, Moeti said. However, she added, surveillance and preparedness activities have been enhanced on both sides of the border.

She says there is extensive monitoring at border crossings and improvements have been made in screening people for the virus. In addition, 2,600 health care workers in Uganda have been vaccinated. Moeti said a similar vaccination campaign began two days ago in South Sudan.

South Sudan is vaccinating health workers against Ebola in case the virus crosses the border from the Democratic Republic of Congo. Ebola has stricken more than 700 people in the DRC and killed more than 400. The World Health Organization said the death rate is 59 percent. 

Half a world away in Ohio, U.S. researchers are racing to develop a new, long-lasting vaccine against Ebola. At Cincinnati Children’s Hospital Medical Center, Dr. Paul Spearman is leading a clinical trial that tests two experimental Ebola vaccines.

“Researchers are looking for new ways to stop these outbreaks and to treat people who become infected and develop Ebola virus disease. The development of preventive vaccines for Ebola is a top global public health priority,” said Spearman, director of the Division of Infectious Diseases at Cincinnati Children’s and the lead investigator in the trial.

Volunteers first receive one of the vaccines. A week later, they get the other one. Spearman said this one-two shot is promising and could provide rapid protection against Ebola.

These are weakened live-vector vaccines that cannot grow in human cells, but they produce strong immune responses to Ebola virus proteins.

Karnail Singh, Ph.D., also at Cincinnati Children’s, heads the program that tests volunteers’ blood samples. The researchers test the samples collected before the volunteers are injected with the experimental vaccines and again afterward.

Singh said that way, researchers can compare the samples and see if the vaccines provide immunity. The researchers also plan to take blood samples six months after the first two injections. If the vaccine is still effective, they hope to repeat the process six months later. These intensive lab studies and the rapid prime-boost schedule have not been done before in developing a vaccine against Ebola.

In Congo, health workers are using a vaccine developed during the Ebola outbreak in West Africa that raged from 2013 until 2016. It protects the Zaire strain of Ebola circulating in Congo. But there are two other deadly strains of Ebola. Health officials want vaccines that protect against all of them. 

The vaccine being tested at Cincinnati Children’s has not yet been compared to the one being used in Congo, but it may protect against at least one other strain of Ebola. The goal is to produce a vaccine that is safe, effective and long-lasting.

The researchers in Cincinnati hope their work will improve the understanding of how to build immunity to other viruses or bacteria that can cause disease.

One of the important aspects of gauging the damage being done to the world’s ecosystems by climate change is knowing the current status of those systems. So a Britain-based charity is about to embark on a seven-week expedition to gauge the health of one of the world’s few remaining pristine reefs. VOA’s Kevin Enochs reports.

The U.S. Environmental Protection Agency added eight members on Thursday to its scientific advisory board tasked with providing independent input for agency policy, a list that includes at least one vocal climate-change doubter.

The EPA said John Christy, an atmospheric science professor at the University of Alabama, was among the new appointees to the advisory body, which now numbers 45 people and includes several appointees from past administrations.

Christy has downplayed the threat of climate change in congressional hearings and media appearances, arguing that scientific models overestimate warming, and that major steps to cut greenhouse gas emissions are not warranted.

Those views place him outside the mainstream scientific consensus, including from U.S. federal agencies, that global warming will have devastating consequences if not urgently addressed. But they dovetail with President Donald Trump’s policy of rolling back Obama-era climate-change regulations to free up more drilling and mining.

Christy did not immediately return a call seeking comment.

New appointees

Other new appointees include Hugh Barton, a toxicology and risk assessment consultant who formerly worked for pharmaceutical giant Pfizer Inc, and Richard Williams, an economics and benefit-cost analysis consultant who previously worked for the Food and Drug Administration.

“In a fair, open, and transparent fashion, EPA reviewed hundreds of qualified applicants nominated for this committee,” acting EPA Administrator Andrew Wheeler said in a statement. They “include experts from a wide variety of scientific disciplines who reflect the geographic diversity needed to represent all 10 EPA regions.”

Wheeler, a former coal industry lobbyist, has said he believes climate change is occurring, but told senators at his confirmation hearing earlier this month that he did not see it as an urgent problem.

Trump downplays climate change

Trump has also repeatedly downplayed the threat of climate change, and announced his intention shortly after taking office in January 2017 to pull the United States from a global accord to fight it.

The science advisory board was created by Congress to serve as a check on EPA policies and research.

The EPA in 2017 barred scientists who have won agency-awarded grants from serving on the panel, a move the administration said was aimed at reducing conflicts of interest, but which environmental groups said would keep qualified scientists out of contention.

The pet parents do yoga poses, like downward-facing dog, as their pups walk around the room and socialize, sniffing each other and the people on their yoga mats. This is doga, a fun, relaxing way to connect with your pet while getting some exercise.

At EMMAvet in Alexandria, Va., owner and veterinarian Veronica Jarvinin decided to begin doga classes a few months ago. She does a bending pose as she pets Emma, her beloved dog whose name is on the sign at the emergency pet care practice.

“Everybody giggles the whole time, and dogs roam from person to person,” she said. “I think it just brings everybody a lot of joy.”

Doga was started by an American fitness coach more than 15 years ago. Some of the poses the dogs do naturally take time for the humans to learn.

“You can do puppy pose where your hips stay up and everything else kind of stays the same,” instructor Ashley Stewart told the group. She is a yoga teacher and dog lover who decided to give teaching doga a try.

“It’s definitely less focused on the human yoga practitioner and more focused on the human and the dog connecting,” she explained. The dogs start to emulate what the humans are doing,” she said, as a black Labrador rested next to its owner who was doing a yoga pose flat on the floor.  But the class also expects unusual distractions, Stewart said with a laugh. “We often have accidents that we are cleaning up or dogs that are barking.”

Doga helps create a stronger bond between the pet parent and pup.

Wendy Kuo, a veterinarian in Maryland, brought her two dogs to her first doga class. “Dogs have so much love to give, and I felt that when I was practicing with them,” she said.

Stewart cuddled a cute little gray poodle that licked her face as she asked the group members to lean over to their ankles. 

Mike Salinas, who has been taking yoga for some time, said the best part of doga is snuggling with the dogs. “All dogs want our affection and attention,” he said. “It’s relaxing. Doga also provides a good workout.”

Stewart pushes the class members to reach up high with their right arms. “We’re just going to hold here for a second,” she said.

Doga newbie Celina Williams found the poses challenging, since she had not taken a yoga class before. She signed up for the class because her dog could come with her, which she thought was great.

College student Beth Barrett arrived without a dog since she can’t fit one in her life right now. “I love dogs and I love yoga,” she said, “so it’s a perfect combination of both.”

As the class ended with the resting pose, both the people and dogs were ready to relax, including Marieka Johnson and her best friend, a sweet terrier mix named Chewy.

“Maybe doga is a little crazy,” she said, “but it brings more of the peace aspect of yoga to you and the animal, and also helps with the bond you create.”

Stewart thanked the class for coming. “The dog lover in me, honors the dog lover in you. Good job, dogs,” she said enthusiastically.
