YouTube to Block Comments on Most Videos Showing Minors

YouTube said Thursday it will disable user comments on a broad array of videos featuring children to thwart “predatory behavior” after revelations about a glitch exploited for sharing of child pornography.

The Google-owned video sharing service announced further steps to crack down on inappropriate comments a week after an investigation showing how comments and connections on child porn were being displayed alongside innocuous videos.

“We recognize that comments are a core part of the YouTube experience and how you connect with and grow your audience,” YouTube said in a posted message to creators.

“At the same time, the important steps we’re sharing today are critical for keeping young people safe.”

YouTube said that during the past week it has suspended comments on tens of millions of videos to prevent users from exploiting of the software glitch for nefarious purposes.

“These efforts are focused on videos featuring young minors and we will continue to identify videos at risk over the next few months,” YouTube said.

“Over the next few months, we will be broadening this action to suspend comments on videos featuring young minors and videos featuring older minors that could be at risk of attracting predatory behavior.”

A small number of video creators will be allowed to keep comments enabled, but will be required to carefully moderate commentary and to deploy software tools provided by YouTube, according to Google.

YouTube accelerated the release of an improved “classifier” that it said will detect and remove twice the number of policy-breaking comments by individuals.

‘Wormhole’

A YouTube creator last week revealed what he called a “wormhole” that allowed comments and connections on child porn alongside videos.

Shortly thereafter, YouTube deleted many comments and blocked some accounts and channels showing inappropriate comments.

Matt Watson, a YouTube creator with some 26,000 subscribers, revealed the workings of what he termed a “wormhole” into a pedophile ring that allowed users to trade social media contacts and links to child porn in YouTube comments.

The post by Watson sparked a series of news reports and boycotts of YouTube ads from major firms.

The incident raised fears of a fresh “brand safety” crisis for YouTube, which lost advertisers last year following revelations that messages appeared on channels promoting conspiracy theories, white nationalism and other objectionable content.

Swiss Study Shows Language Learning During Sleep

A new study suggests you can learn language while you sleep.

Researchers from Switzerland’s University of Bern say they discovered people were able to learn new language words during deep levels of sleep. Results of the study that recently appeared in the publication Current Biology and other studies suggest the same findings.

The research group was led by Katharina Henke, a professor at the University of Bern and founder of the school’s Center for Cognition, Learning and Memory. The group carried out experiments on a group of young German-speaking men and women.

During normal sleep, human brain cells are alternately active and inactive. The Swiss experiments centered on periods of slow-wave peaks or deep sleep called “up-states,” which the researchers say are the best moments for sleep learning.  

Researchers observed individuals in a controlled environment and recorded brain activity as pairs of words were played for the study subjects. One word in the pair was a real German word. The other was a made-up foreign word.

Each word pair was played four times with the order changed each time. The goal was to create a lasting memory link between the false word and the German word that individuals could identify when awake.  

When the subject woke, they were presented with the false language words – both by sight and sound. They were tested on the false words played during sleep.             

During this part of the experiment, some subjects had their brain activity recorded by magnetic imaging technology to measure brain activity when subjects were answering questions.

Results of the study found that a majority of subjects gave more correct answers about the sleep-learned words than would be expected if they had only guessed. Researchers said memory was best for word pairs presented during slow-wave peaks during sleep.

The researchers say more study is needed to support their findings. However, the experiments provide new evidence that memories can be formed and vocabulary learning can take place in both conscious and unconscious states.

 

Thai Lawmakers Approve Controversial Cybersecurity Act

Thailand’s legislature has passed a cybersecurity bill that would allow authorities access to people’s personal information without a court order.

The Cybersecurity Act addresses computer hacking crimes, but activists fear it will allow the government sweeping access to people’s personal information.

The National Legislative Assembly, which passed the bill in its final reading Thursday by a vote of 133-0, was appointed by the junta that came to power after a 2014 coup. It becomes law when published in the Royal Gazette.

The cybersecurity bill allows state officials to seize, search, infiltrate, and make copies of computers, computer systems and information in computers without a court warrant if an appointed committee sees it as a high-level security threat, and relevant courts can later be informed of such actions.

How ‘Completely Avoidable’ Measles Cases Continue to Climb

The U.S. has counted more measles cases in the first two months of this year than in all of 2017, and part of the rising threat is misinformation that makes some parents balk at a crucial vaccine, federal health officials told Congress Wednesday.

Yet the vaccine is hugely effective and very safe — so the rise of measles cases “is really unacceptable,” said Dr. Anthony Fauci, infectious disease chief at the National Institutes of Health.

The disease was declared eliminated in the U.S. in 2000, which means it was not being spread domestically. But cases have been rising in recent years, and 2019 is shaping up to be a bad one.

Republican and Democratic lawmakers at the House Energy and Commerce subcommittee hearing bemoaned what’s called “vaccine hesitancy,” meaning when people refuse or delay vaccinations.

“These outbreaks are tragic since they’re completely avoidable,” said Rep. Brett Guthrie, R-Ky.

“This is a public health problem for which science has already provided a solution,” agreed Rep. Frank Pallone, D-N.J.

WATCH: Measles on the Rise Around the World

 

Here are some questions and answers about measles:

Q: How dangerous is measles?

A: Measles typically begins with a high fever, and several days later a characteristic rash appears on the face and then spreads over the body. Among serious complications, 1 in 20 patients get pneumonia, and 1 in 1,000 get brain swelling that can lead to seizures, deafness or intellectual disability.

While it’s rare in the U.S., 1 or 2 of every 1,000 children who get measles dies, according to the Centers for Disease Control and Prevention.

Q: How does it spread?

A: By coughing or sneezing, and someone can spread the virus for four days before the telltale rash appears, Fauci warned.

The virus can live for up to two hours in the air or on nearby surfaces. Nine of 10 unvaccinated people who come into contact with someone with measles will catch it. Fauci called it “one of the most contagious viruses known to man.”

Q: How widespread is measles?

A: In the U.S., the CDC has confirmed 159 cases so far this year in 10 states: California, Colorado, Connecticut, Georgia, Illinois, Kentucky, New York, Oregon, Texas, and Washington. That compares to 372 cases last year, and 120 in 2017.

But measles is far more common around the world. The World Health Organization said measles claimed 110,000 lives in 2017. The WHO says there’s been a 30 percent increase in measles cases in recent years. Unvaccinated Americans traveling abroad, or foreign visitors here, can easily bring in the virus.

For example, a huge outbreak in Madagascar has caused more than 68,000 illnesses and 900 deaths since September. But you don’t need to go as far as Madagascar, common tourist destinations like England, France, Italy and Greece had measles outbreaks last year, noted CDC’s Dr. Nancy Messonnier. Nearly 83,000 people contracted measles in Europe in 2018, the highest number in a decade.

Q: How many U.S. children are vulnerable?

A: Overall about 92 percent of U.S. children have gotten the combination vaccine that protects against measles, mumps and rubella, known as the MMR vaccine. Two shots are required, one around the first birthday and a second between age 4 and 6. Full vaccination is 97 percent effective at preventing measles.

But the CDC says 1 child in 12 doesn’t receive the first dose on time, and in some places vaccination rates are far lower than the national average. For example, an outbreak in Washington state is linked to a community where only about 80 percent of children were properly vaccinated.

Q: Is the vaccine safe?

A: Yes, said Fauci and Messonnier, who point to decades of use by millions of children each year — and who made sure their own children were vaccinated.

In the late 1990s, one study linked MMR vaccine to autism but that study was found to be a fraud, and Fauci said later research found no risk of autism from the vaccine.

Still, misinformation about MMR safety is widespread. Fauci said the solution isn’t to criticize people who have no way to know what’s false. Instead, “we need to education them to show them what the evidence is.”

Q: Why isn’t everyone vaccinated?

A: Some people can’t be immunized for medical reasons, including infants and people with weak immune systems, and most states allow religious exemptions. But while vaccination against a list of contagious diseases is required to attend school, 17 states allow some type of non-medical exemption for “personal, moral or other beliefs,” according to the National Conference of State Legislatures.

In Washington state, lawmakers are debating ending that personal or philosophical exemption, as are several other states. California ended a similar exemption in 2015 after a measles outbreak at Disneyland sickened 147 people and spread across the U.S. and into Canada.

Congo Ebola Center Set on Fire After Armed Attack

Armed assailants attacked an Ebola treatment center in eastern Democratic Republic of Congo on Wednesday, setting off a fire and becoming embroiled in an extended gun battle with security forces, health officials said.

The identity and motive of the assailants were unclear. Aid workers have faced mistrust in some areas as they work to contain an Ebola outbreak.

Dozens of armed militia also regularly attack civilians and security forces in eastern Congo’s borderlands with Uganda and Rwanda, which has significantly hampered the response to the disease.

The health ministry said in a statement that 38 suspected Ebola patients and 12 confirmed cases were in the center at the time of the attack. Four of the patients with confirmed cases fled and are being looked for, it said.

None of the patients who have been accounted for were injured, nor were any staff members, the ministry added. 

French medical charity Medecins Sans Frontieres (MSF), which runs the center together with the ministry, condemned the “deplorable attack” and said its efforts were focused on the immediate safety of patients and staff.

The attack in the city of Butembo was the second in Congo’s Ebola-hit east this week. On Sunday unidentified assailants set fire to a treatment center in the nearby town of Katwa, killing a nurse.  

The current Ebola outbreak, first declared last August, is the second deadliest of the hemorrhagic fever since it was discovered in Congo in 1976. It is believed to have killed at least 553 people so far and infected over 300 more.

Walmart Is Eliminating Greeters, Worrying Disabled Workers

As Walmart moves to phase out its familiar blue-vested “greeters” at 1,000 stores nationwide, disabled workers who fill many of those jobs say they’re being ill-treated by a chain that styles itself as community-minded and inclusive. 

 

Walmart told greeters around the country last week that their positions would be eliminated on April 26 in favor of an expanded, more physically demanding “customer host” role. To qualify, they will need to be able to lift 25-pound (11-kilogram) packages, climb ladders and stand for long periods. 

 

That came as a heavy blow to greeters with cerebral palsy, spina bifida and other physical disabilities. For them, a job at Walmart has provided needed income, served as a source of pride and offered a connection to the community.  

Customer backlash

 

Now Walmart, America’s largest private employer, is facing a backlash as customers rally around some of the chain’s most highly visible employees. 

 

Walmart says it is striving to place greeters in other jobs at the company, but workers with disabilities are worried.  

 

Donny Fagnano, 56, who has worked at Walmart for more than 21 years, said he cried when a manager at the store in Lewisburg, Pa., called him into the office last week and told him his job was going away.  

 

“I like working,” he said. “It’s better than sitting at home.” 

 

Fagnano, who has spina bifida, said he was offered a severance package. He hopes to stay on at Walmart and clean bathrooms instead. 

 

Walmart greeters have been around for decades, allowing the retail giant to put a friendly face at the front of its stores. Then, in 2016, Walmart began replacing greeters with hosts, adding responsibilities that include helping with returns, checking receipts to deter shoplifters and keeping the front of the store clean. Walmart and other chains have been redefining roles at stores as they compete with Amazon.  

The effect of the greeter phase-out on disabled and elderly employees — who have traditionally gravitated toward the role as one they were well-suited to doing — largely escaped public notice until last week, when Walmart launched a second round of cuts. 

 

As word spread, first on social media and then in local and national news outlets, outraged customers began calling Walmart to complain. Tens of thousands of people signed petitions. Facebook groups sprang up with names like “Team Adam” and “Save Lesley.” A second-grade class in California wrote letters to Walmart’s CEO on behalf of Adam Catlin, a disabled greeter in Pennsylvania whose mother had written an impassioned Facebook post about his plight. Walmart said it has offered another job to Catlin. 

 

In Galena, Ill., hundreds of customers plan to attend an “appreciation parade” for Ashley Powell on her last day of work as a greeter. 

 

“I love it, and I think I’ve touched a lot of people,” said Powell, 34, who has an intellectual disability. 

‘What am I going to do?’

 

In Vancouver, Wash., John Combs, 42, who has cerebral palsy, was devastated and then angered by his impending job loss. It had taken his family five years to find him a job he could do, and he loved the work, coming up with nicknames for all his co-workers. 

“What am I going to do — just sit here on my butt all day in this house? That’s all I’m going to do?” Combs asked his sister and guardian, Rachel Wasser. “I do my job. I didn’t do anything wrong.” 

 

Wasser urged the retailer to “give these people a fair shake. … If you want to make your actions match your words, do it. Don’t be a wolf in sheep’s clothing.” 

 

With the U.S. unemployment rate for disabled people more than twice that for workers without disabilities, Walmart has long been seen as a destination for people like Combs. Advocacy groups worry the company is backsliding.  

“It’s the messaging that concerns me,” said Gabrielle Sedor, chief operations officer at ANCOR, a trade group representing service providers. “Given that Walmart is such an international leader in the retail space, I’m concerned this decision might suggest to some people that the bottom line of the company is more important to the company than inclusive communities. We don’t think those two are mutually exclusive.” 

 

The greeter issue has already prompted at least three complaints to the U.S. Equal Employment Opportunity Commission, as well as a federal lawsuit in Utah alleging discrimination under the Americans with Disabilities Act. Under the federal law, employers must provide “reasonable” accommodations to workers with disabilities. 

 

Walmart did not disclose how many disabled greeters could lose their jobs. The company said that after it made the change at more than 1,000 stores in 2016, 80 percent to 85 percent of all affected greeters found other roles at Walmart. It did not reveal how many of them were disabled. 

 

This time, Walmart initially told greeters they would have 60 days to land other jobs at the company. Amid the uproar, the company has extended the deadline indefinitely for greeters with disabilities. 

 

“We recognize that our associates with physical disabilities face a unique situation,” Walmart spokesman Justin Rushing said in a statement. The extra time, he said, will give Walmart a chance to explore how to accommodate such employees. 

Offers made

 

Walmart said it has already made offers to some greeters, including those with physical disabilities, and expects to continue doing so in the coming weeks.  

 

But some workers say they have been tacitly discouraged from applying for other jobs. 

 

Mitchell Hartzell, 31, a full-time Walmart greeter in Hazel Green, Ala., said his manager told him “they pretty much didn’t have anything in that store for me to do” after his job winds down in April. He said he persisted, approaching several assistant managers to ask about openings, and found out about a vacant position at self-checkout. But it had already been promised to a greeter who doesn’t use a wheelchair, he said. 

 

“It seems like they don’t want us anymore,” said Hartzell, who has cerebral palsy. 

 

Jay Melton, 40, who has worked as a greeter in Marion, N.C., for nearly 17 years, loves church, Tar Heels basketball and Walmart. His sister-in-law, Jamie Melton, said the job is what gets him out of bed. 

 

“He doesn’t have a lot of things he does himself that bring him joy,” she said. Addressing Walmart, Melton added: “When you cut a huge population of people out, and you have written a policy that declares they are no longer capable of doing what they have been doing, that is discrimination.”  

World Bank: Women Have Just 75 Percent of Men’s Legal Rights

Women around the world are granted only three-quarters of the legal rights enjoyed by men, often preventing them from getting jobs or opening businesses, the World Bank said in study published Wednesday. 

 

“If women have equal opportunities to reach their full potential, the world would not only be fairer, it would be more prosperous as well,” Kristalina Georgieva, the bank’s interim president, said in a statement. 

 

While reforms in many countries are a step in the right direction, “2.7 billion women are still legally barred from having the same choice of jobs as men,” the statement said. 

 

The study included an index measuring gender disparities that was derived from data collected over a decade from 187 countries and using eight indicators to evaluate the balance of rights afforded to men and women. 

 

The report showed progress over the past 10 years, with the index rising to 75 from 70, out of a possible 100, as 131 countries have agreed to enact 274 reforms, adopting laws or regulations allowing greater inclusion of women. 

 

Among the improvements, 35 countries have proposed laws against sexual harassment in the workplace, granting protections to an additional 2 billion women, while 22 nations have abolished restrictions that kept women out of certain industrial sectors. 

 

Six perfect scores

Six nations — Belgium, Denmark, France, Latvia, Luxembourg and Sweden — scored a 100, “meaning they give women and men equal legal rights in the measured areas,” the World Bank said. 

 

A decade ago, no economy had achieved a perfect score. 

 

On the other hand, too many women still face discriminatory laws or regulations at every stage of their professional lives: 56 nations made no improvement over the last decade. 

 

South Asia saw the greatest progress, although it still achieved a relatively low score of 58.36. It was followed by Southeast Asia and the Pacific, at 70.73 and 64.80, respectively.  

 

Latin America and the Caribbean recorded the second-highest scores among emerging and developing economies at 79.09. 

 

Conversely, the Middle East and North Africa posted the lowest score for gender equality at 47.37. The World Bank nevertheless pointed to encouraging changes, such as the introduction of laws against domestic violence, in particular in Algeria and Lebanon.

TikTok Fined in US for Illegally Gathering Children’s Data 

The fast-growing, Chinese-owned video sharing network TikTok agreed to pay a $5.7 million fine to U.S. authorities to settle charges that it illegally collected personal information from children, officials said Wednesday. 

 

The Federal Trade Commission said the penalty for the social network, which had been known as Musical.ly, was the largest ever in a children’s privacy investigation. 

 

The social network, which has been surging in popularity with young smartphone users and taking over from rivals like Facebook, Instagram and Snapchat, failed to obtain parental consent from its underage users as required by the Children’s Online Privacy Protection Act, FTC officials said. 

 

The operators of TikTok “knew many children were using the app, but they still failed to seek parental consent before collecting names, email addresses, and other personal information from users under the age of 13,” said FTC Chairman Joe Simons.  

No tolerance for lawbreakers

 

“This record penalty should be a reminder to all online services and websites that target children: We take enforcement of COPPA very seriously, and we will not tolerate companies that flagrantly ignore the law.” 

 

TikTok claimed 500 million users worldwide last year, making it one of the most popular worldwide apps. 

 

Owned by China’s ByteDance, it expanded its reach in the U.S. with the merger with Musical.ly. 

 

Teens have been flocking to the service, which allows them to create and share videos of 15 seconds.  

According to the FTC, the company required users to provide an email address, phone number, username, first and last name, a short biography, and a profile picture. 

 

The consumer protection regulator said 65 million accounts have been registered in the United States. 

 

Officials said the company knew that many of its users were under 13 and should have taken greater precautions. 

 

“In our view, these practices reflected the company’s willingness to pursue growth even at the expense of endangering children,” said a statement from FTC Commissioners Rohit Chopra and Rebecca Kelly Slaughter. 

 

“The agency secured a record-setting civil penalty and deletion of ill-gotten data, as well as other remedies to stop this egregious conduct.” 

Suggestive content

 

TikTok has faced criticism around the world for featuring sexually suggestive content inappropriate for children. 

 

TikTok said in a statement it would create a “separate app experience” for younger users with additional privacy protections as part of its agreement with regulators. 

 

“It’s our priority to create a safe and welcoming experience for all of our users, and as we developed the global TikTok platform, we’ve been committed to creating measures to further protect our user community — including tools for parents to protect their teens and for users to enable additional privacy settings,” the statement said.

Fed to Stop Shrinking Portfolio This Year, Powell Says 

The Federal Reserve will stop shrinking its $4 trillion balance sheet later this year, Fed Chairman Jerome Powell said on Wednesday, ending a process that investors say works at cross-purposes with the Fed’s current pause on interest rate hikes. 

“We’ve worked out, I think, the framework of a plan that we hope to be able to announce soon that will light the way all the way to the end of balance sheet normalization,” Powell told members of the House Financial Services Committee in what were his most detailed remarks to date on the subject. 

“We’re going to be in a position … to stop runoff later this year,” he said, adding that doing so would leave the balance sheet at about 16 percent or 17 percent of GDP, up from about 6 percent before the financial crisis about a decade ago. 

The U.S. gross domestic product is currently about $20 trillion, suggesting the Fed’s balance sheet would be between $3.2 trillion and $3.4 trillion. 

The Fed has been trimming its balance sheet — bulked up by trillions of dollars of bond-buying during the post-crisis years to help keep interest rates low and bolster the economy — by as much as $50 billion a month since October 2017. As recently as a few months ago it had expected to keep shrinking its portfolio for another couple of years. 

New tack

But in a series of meetings that began in November, the Fed has been devising a new approach. With rising demand for currency around the world, and from U.S. banks for reserves held at the central bank, Fed policymakers now believe a big balance sheet is necessary just to ensure it has proper control over the short-term interest rates it sets to manage the economy. 

In addition, Fed policymakers now say balance sheet policy should take financial and economic conditions into account. 

Questions about the plan remain, including whether the Fed will adjust the maturities of its Treasury portfolio, and how it will go about shedding the mortgage-backed securities (MBS) it accumulated during its asset-buying days. 

Powell said the Fed still has a bunch of decisions ahead of it. 

“The one on MBS sales is really closer to the back of the line — really, we have to decide about the maturity composition, things like that, and we’ll be working through that in a very careful way,” Powell said.  “Markets are sensitive to this.” 

Powell’s remarks on the balance sheet came toward the end of more than two hours of testimony before the Democrat-led House panel that includes several new members, including New York Democrat Alexandria Ocasio-Cortez. 

But the Green New Deal advocate and Bronx populist asked no questions during the debate, and much of what Powell said on Wednesday repeated comments made Tuesday to the Republican-controlled Senate Banking Committee, including that the economy is on solid ground and the Fed would be patient on raising rates. 

Inflation goal unchanged

Powell was asked, as he was in the Senate, about the Fed’s plan to rethink its policy framework this year. He assured lawmakers that the Fed is merely trying to refine its approach so it can meet its current 2 percent inflation goal. 

“We are not looking at a higher inflation target, full stop,” he said. 

Powell also repeated his warnings against a failure by Congress to raise the debt ceiling, saying there would be “bad consequences” should the United States default on its debt payments. 

Powell by law appears two times a year before Congress to brief members of the House Financial Services Committee and the Senate Banking Committee on monetary policy and the state of the economy. 

Meet Elon Tusk: Tesla Chief Changes Twitter Display Name

Silicon Valley billionaire Elon Musk changed his Twitter display name to “Elon Tusk” in another late-night flurry of tweets on Wednesday, which also promised news from his electric carmaker Tesla Inc later this week.

In a series of tweets to his 25 million followers following charges from the U.S. Securities and Exchange Commission earlier this week, Musk accused the regulator of failing to read Tesla’s annual reports and said its oversight was “broken”.

On Wednesday, he changed his display name and added an elephant tag.

Social media platforms have featured a number of memes involving wordplay around Musk’s name this week.

He also promised Tesla would have “news” at 2 p.m. California time on Thursday. The company, deep in debt as it ramps up production of its popular Model 3 sedan, is due to repay a $920 million convertible bond a day later.

Musk had promised last year to have his public statements vetted by the company’s board, as part of a settlement with the SEC that headed off demands for him to resign as Tesla CEO.

Tesla did not immediately respond to request for comment.

 

Parkinson’s Drug Trial Offers Glimmer of Hope for Brain Cells

An experimental drug could offer hope for restoring damaged brain cells in Parkinson’s patients, scientists said on Wednesday, although they cautioned that a clinical trial was not able to prove the treatment slowed or halted the neurodegenerative disease.

The trial involved delivery of a protein therapy directly into the brains of Parkinson’s patients. Scientists said some brain scans revealed “extremely promising” effects on damaged neurons of those who received the treatment.

“The spatial and relative magnitude of the improvement in the brain scans is beyond anything seen previously in trials,” said Alan Whone, a Parkinson’s specialist at Britain’s Bristol University who co-led the trial.

Researchers said the therapy warranted further investigation even though it failed to demonstrate improvement of symptoms in patients who received it when compared to others given a placebo.

“The primary outcome was disappointing,” Whone told reporters at a briefing in London.

Parkinson’s is a neurodegenerative disease that affects around one percent to two percent of people over age 65. It causes tremors, muscle stiffness and movement and balance problems. Although some medicines can improve symptoms, there is no cure or treatment that can slow progression of the disease.

This trial involved 41 patients who all underwent robot-assisted surgery to have tubes placed into their brains.

That allowed doctors to infuse either the experimental treatment – called Glial Cell Line Derived Neurotrophic Factor (GDNF) – or a placebo directly to the affected brain areas. GDNF is made by privately-held Canadian biotech firm MedGenesis Therapeutix.

Half of the patients were given monthly GDNF infusions and half received monthly placebo infusions. After nine months, all participants were offered the GDNF infusions for a further nine months.

Results showed some signs of improvements, Whone said, but there was no significant difference between the treatment and placebo groups. He said this was in part due to the sizeable placebo effect in this trial.

The placebo effect has been known to confound clinical trials of treatments for conditions involving the brain, boosted by patients’ expectations that a potential treatment will work.

But the brain scan results suggested the drug might be starting to reawaken damaged brain cells. After nine months, there was no change in the scans of patients who received a placebo, but those who got GDNF showed major changes in a key area of the brain affected by the disease.

Whone said this suggested GDNF could be “a means to possibly reawaken and restore” brain cells that are gradually destroyed in Parkinson’s.

Scientists Study Tiny Creatures With Big Impact on the Ocean

It’s not just human workers who commute each day. Millions of tiny creatures that form the base of the ocean food chain migrate in giant swarms each night. They go up and down – from deep waters to the surface to feed, then back to the depths as dawn breaks. Scientists are looking at how this vertical commute affects the ocean, which is a key regulator of climate by storing and transporting heat, carbon, nutrients and freshwater around the world.

Noise-weary New York Ponders a Gentler, European-style Siren

If two New York City lawmakers get their way, the long, droning siren from police cars, fire trucks and ambulances that has been part of the city’s soundtrack for generations — WAAAAAhhhhhhh — would be replaced by a high-low wail similar to what’s heard on the streets of London and Paris — WEE-oww-WEE-oww-WEE-oww.

Their reasons for the switch: The European-style siren is less shrill and annoying and contributes less to noise pollution.

“I’ve been hearing from constituents complaining that the current sirens in New York are a high-pitched, continuous noise — a nuisance,” says Helen Rosenthal, an Upper West Side Democrat and one of the sponsors of the proposal.

Noise is consistently among the most frequent complaints to the city’s hotline, with many calls about the loud sirens that blare 24/7, wake people from their slumber and cause dogs to howl in unison. 

“Europeanizing” New York sirens would not change the decibel level — still topping out at roughly 118 — but would lower the frequency and thus make the sirens less shrill but still ear-catching enough to grab attention. 

“The alternating high-low siren required by this legislation is not as piercing,” adds co-sponsor Carlina Rivera, a Manhattan Democrat.

If approved in a council vote — which has yet to be scheduled — the legislation would require sirens on all emergency vehicles to transition within a two-year period.

Buzz about the bill even made it to last week’s NBC “Saturday Night Live,” where a “Weekend Update” anchor joked that with the European-style siren, “You can spend your ride in the ambulance pretending you have universal health care.”

City council members are looking closely at the experience of the city’s Mount Sinai Health System, which already uses the two-tone siren in its 25 ambulances that make about 100,000 trips a year. The switch was made last year after decades of complaints from residents of the Upper East Side home of the hospital complex. 

At community board meetings, Mount Sinai’s Emergency Medical Services Director Joseph Davis played various siren options to find out which one locals preferred.

 “People hated them all,” Davis said, “but the `high-low’ was least intrusive. It didn’t have that piercing sound.”

Davis, a 40-year EMS veteran who suffers from hearing damage that he blames on repeated exposure to sirens, said the change was simple and cost effective: All it took was reprogramming the electronic box in each vehicle, which comes preloaded with seven different sounds with names such as “Wail,” “Yelp” and “Piercer.” 

In fact, many ambulances, fire trucks and police cars are equipped with alternate sirens and horns that they can employ in certain situations, such as in traffic when cars and pedestrians just won’t get out of the way. They include short blips and the “Rumbler” low-frequency, vibrating siren aimed at motorists who may otherwise be unable to hear higher frequencies.

For some Manhattanites, any change in the city’s daily siren song would be welcomed.

“I always have to cover my ears with my hands when a siren-blaring ambulance passes,” says Louise Belulovich, a Manhattan attorney. “If I’m carrying packages and unable to, then what is an annoying experience becomes a painful one.”

But Linda Sachs, a longtime resident of Manhattan’s Upper West Side who lives near one of the Mount Sinai hospitals that uses the new European siren, doesn’t think the change is for the good. She prefers the old New York standard.

“The old sirens never woke me up, but these make me shudder,” Sachs says, adding that she understands city lawmakers are attempting to do something about noise pollution. “But the old sound wasn’t as obnoxious.”

 

 

 

Cameroon Cracks Down on Illegal Fuel Trade

Cameroonian police officers, assisted by members of the country’s elite corps, seized hundreds of containers of fuel illegally transported from Nigeria by suspected Central African Republic rebels in the northern town of Mbe, Cameroon.

Rigobert Ojong, a member of a task force of military, police and civil society members created three weeks ago to stop the illegal fuel trade, said the group received a tip that the fuel was on its way to the C.A.R., where it would be used by rebels fighting the central African state’s government. 

“We have put aside personnel dedicated to this fight, within the framework of this task force, and we have been able to intercept about 1,500 drums of fraudulently imported fuel. If we go by the price in the black market, we are talking about more than 3 billion CFA francs [$5 million] a year,” Ojong said.

Cameroon’s government says an unknown quantity of oil is smuggled from Nigeria through its territory because the border is so porous. The military says it has opened an investigation to track dealers who might be collaborating with rebel groups in the C.A.R.

Alleged corruption

Businessman Patrice Essola, who supplies fuel to the C.A.R. from Cameroon, says illegal trade with C.A.R. rebels is facilitated by corrupt government officials in both countries.

He said the rebels and traffickers work in collaboration with corrupt Cameroonian military officials and C.A.R. border immigration staff to import the fuel from Nigeria. Some of the tankers and trucks that smuggle the fuel are even protected by corrupt officials while in Cameroon and in the C.A.R., Essola added.

Kildadi Taguieke Boukar, governor of the Adamawa region that shares a border with the C.A.R., denies corrupt military officials assist rebels and smugglers, but said investigations had been opened.

Each time the traffickers are arrested, they answer charges in courts of law, Boukar said, but added the task is very, very difficult because Cameroon’s borders with Nigeria and the C.A.R. are very porous. All of the fuel will be taken to C.A.R. authorities, he said.

C.A.R. violence, peace deal

In January, Cameroon said 300 of its citizens had been abducted by suspected C.A.R. rebels within the past two years, along with at least 5,000 cattle. Local border communities asked the government to authorize self-defense groups to be equipped with guns to face rebels who they said continued to cross to their villages for supplies.

The C.A.R. was plunged into turmoil in 2013 when Muslim rebels known as the Seleka seized power in the majority-Christian country. A band of mostly Christian militias, called the anti-Balaka, rose up to counter the Seleka. Thousands of people have been killed in the violence and more than one million are internally displaced. An estimated 570,000 people have fled to neighboring countries, with about 350,000 in Cameroon.

On Feb. 2, the U.N. mission in the C.A.R., known as MINUSCA, and the African Union announced that a peace deal between the C.A.R. government and 14 rebel groups had been reached after sponsored talks in Sudan. They called on the C.A.R.’s neighbors to help bring peace by not allowing their borders to be used for supplies or as a hiding ground for fighters who refuse to respect the deal.

Boeing Nominates Former UN Ambassador Haley to Join its Board

U.S. aerospace manufacturer Boeing said on Tuesday it has nominated Nikki Haley, former U.S. ambassador to the United Nations and a close ally of President Donald Trump, to join its board of directors at the company’s annual shareholders meeting on April 29.

If elected by Boeing shareholders, she would help guide the future of America’s largest exporter, with a network of suppliers across the United States and the world, as Washington and Beijing have been locked in intense negotiations to end a trade war.

Haley’s nomination comes as Boeing grapples with a major decision: whether to launch an all-new jetliner known as NMA, a midsize plane that would serve a niche market falling between narrow- and wide-body aircraft.

The world’s largest planemaker has said it would make a final launch decision in 2020 on the new program, which is expected to define competition with archrival Airbus SE.

Viewed as a rising Republican Party star, Haley has often been mentioned as a future presidential candidate. Her counterparts at the United Nations saw her as a voice of clarity in the Trump administration.

Haley, 47, is the first female governor of South Carolina and a three-term legislator in the South Carolina House of Representatives. As governor in 2015, Haley was a key opponent of a campaign by Boeing’s largest labor union to form a collective bargaining unit at its 787 Dreamliner factory in South Carolina – though the machinists were later successful in forming a small bargaining unit there.

Boeing has faced growing scrutiny over its links to the Trump administration after a former senior planemaking executive, Pat Shanahan, was named deputy defense secretary and later acting defense secretary. The 31-year Boeing veteran has recused himself, however, from matters relating to the aerospace company.

The U.S. government has been weighing the purchase of an advanced version of the F-15 Boeing fighter. Last year, Boeing’s defense side had a series of wins, including the U.S. Air Force’s next training jet, which could be worth up to $9.2 billion, as well as a contract to replace UH-1N Huey helicopters worth $2.4 billion over the life of the programs.

In a press release, Muilenburg praised Haley’s record in government and industry partnership.

“Boeing will benefit greatly from her broad perspectives and combined diplomatic, government and business experience to help achieve our aspiration to be the best in aerospace and a global industrial champion,” Muilenburg said.

Based on total compensation for Boeing’s other 13 board members, Haley can expect to earn more than $300,000, well above her salary as U.N. ambassador.

Separately on Tuesday, the shareholders of Brazilian planemaker Embraer SA approved a deal to sell 80 percent of the Sao Paulo-based company’s commercial jet division to Boeing, a move that could reshape the global market for aircraft of up to 150 seats.

Boeing shares were flat at $427.88 a share in afternoon trading on the New York Stock Exchange.

Poll: Brazilians Split on Pension Reform, But Back Bolsonaro 

Brazilians are split on a proposed overhaul of the country’s pension system, a poll showed on Tuesday, while most said they approve of right-wing President Jair Bolsonaro’s performance.

In one of the first major surveys since Bolsonaro’s Jan. 1 inauguration, 45.6 percent of respondents said they disapprove of the proposed pension reform, while 43.4 percent said they approve. The rest said they did not know or did not respond.

It was the first time a poll, conducted by the MDA institute and commissioned by the CNT transportation lobby, directly asked respondents if they approved of pension reform.

Other polls in the past year have shown large swings in voter opinion on pension reform, from over two-thirds against to figures in line with the MDA survey.

Bolsonaro’s proposal to address a widening pension deficit by raising taxes, delaying retirements and creating individual savings accounts is the cornerstone of his economic agenda.

Last week, the president delivered his proposal to Congress, aiming to save over 1 trillion reais ($266 billion) in the next decade. Most economists agree the system must be overhauled to shore up public finances and foster growth.

On Bolsonaro’s popularity, 57.5 percent approved of his performance, while 28.2 percent disapproved and 14.3 percent did not offer an opinion.

In the survey, 38.9 percent said Bolsonaro’s government was “good” or “excellent,” 29 percent said it was “regular” and 19 percent said it was “bad” or “terrible.”

MDA surveyed 2,002 Brazilians between Feb. 21 and 23. The poll has a margin of error of 2.2 percentage points.

 

Mobile World Congress Overshadowed by Huawei 5G Spying Standoff

Robots, cars, drones and virtual-reality gaming sets connected by cutting-edge 5G networks are among the thousands of futuristic gadgets on display at this year’s Mobile World Congress in Barcelona, Spain.

While there is much excitement over how 5G will transform our everyday lives, the conference is overshadowed by the standoff between the United States and Beijing over the Chinese telecoms giant Huawei, which the U.S. says could be used by the Chinese government for espionage.

Some U.S. cities and parts of Asia are already operating 5G mobile networks. They offer speeds of over a gigabyte per second and low latency — in other words, practically instant connections with no delay.

Experts say that opens up whole new fields of connectivity, from new generations of virtual reality gaming and communication, to remote robotic surgery.

The technology promises to transform not only the mobile phone in your pocket — but also the world around us, says Paul Triolo of the Eurasia Group, who spoke to VOA from the conference.

“The really key aspects of 5G, like some of the low latency communications and massive sensor, massive machine-to-machine communications, that’s more about industry and industrial uses. And that gets into thing like critical infrastructure so you’re going to have a lot more non-personal or industrial data flying around and that really has people concerned. For example, military forces in countries like the U.S. will also leverage large parts of the commercial network,” said Triolo.Chinese firm Huawei is a big presence at the Mobile World Congress and a big player in 5G network technology.

Washington has banned the company from 5G rollout in the United States, citing Chinese legislation requiring companies to cooperate with the state — raising fears Huawei 5G networks overseas could be used as a ‘Trojan horse’ to spy on rivals.

Attending the Mobile World Congress Tuesday, the U.S. State Department’s Deputy Secretary for Cyber Policy Robert L. Strayer urged allies to do the same.

“We will continue to engage with these governments and the regulators in these countries to educate them about what we know and keep sharing the best practices for how we can all successfully move to next generation of technology. I´ll just say there are plenty of options in the West,” Strayer told reporters.

Huawei’s management has said the company would never use ‘back doors’ for espionage — and the Chinese government has dismissed the accusations.

Australia, New Zealand and Japan have followed Washington’s lead and restricted Huawei’s involvement in 5G. Europe remains undecided — but the industry needs clarity, said analyst Paul Triolo.

“The European community in particular and also the U.S. have to clarify what these policies mean, what a ban would mean or what some kind of a partial ban would mean, if there’s really a middle ground that can be found here.”

Vodafone’s CEO Nick Read told the Barcelona conference that banning Huawei could set Europe’s 5G rollout back another two years.

The eye-catching gadgets show the potential that 5G networks are about to unleash. But the question of who controls those networks, and the data they carry, looms large over this futuristic world.

Look But Don’t Touch as Smartphone’s Flexible Future Unfolds

Flexible and folding formats framed the future of smartphones this week as manufacturers focused on new forms in an effort to jolt the market out of uniformity and re-invigorate sales.

But anyone hoping to tap or swipe Huawei’s Mate X, a smartphone that wraps the screen around the front and back, was soon disappointed at Barcelona’s Mobile World Congress.

Initial cheers were quickly followed by gasps when the Chinese firm revealed its eye-watering 2,299 euros ($2,600) price tag, although that includes a 5G connection.

This is even more than Samsung’s Galaxy Fold, which was unveiled last week and will be priced from $1,980 when it goes on sale in some markets in April. It was on display in Barcelona in a glass case like a museum artefact.

While the hands-off stance indicates neither firm has a consumer-ready device, 2019 would be remembered as the year of the foldable Ben Wood, chief of research at CCS Insight, said, adding that the new format was still in its infancy.

“But we are at the stone age of devices with flexible displays; it’s a whole new phase of experimentation after the sea of smartphone sameness we have seen for the last decade.”

Samsung took the opposite approach to Huawei by putting its folding screen on the inside of its device, with another smaller screen on the front panel for use when its is closed.

“That was the solution we felt was best for longevity,” Samsung’s European Director of Mobile Portfolio & Commercial Strategy Mark Notton told Reuters.

Smartphone makers have been trying to innovate to persuade consumers to upgrade from devices which already meet most of their needs, in an effort to reverse falling sales.

And although more vendors will soon follow with their own takes on foldable displays, 2019 will not be the year they go mainstream, market analysts Canalys said. They will remain exclusively ultra-luxury devices with fewer than 2 million expected to be shipped worldwide this year, Canalys added.

The mobile market slipped 1.2 percent in 2018, research company Gartner says, although it expects growth of 1.6 percent in 2019, driven by replacement cycles in the largest and most saturated markets China, the United States and Western Europe.

Gearing up for 5G

With 5G next generation mobile networks not becoming widely available until 2023 in the United States and China and 2026 in Europe, analysts say, the vast majority of customers will be buying the latest 4G devices like Samsung new Galaxy S10.

Nonetheless, manufacturers such as LG were keen to show they could squeeze 5G technology into 4G smartphone form, although most lacked launch or pricing information.

Chinese maker OnePlus had a 5G device running a video game using a 5G connection on show, but visitors were teased with only a glimpse of the phone’s screen in a display cabinet.

“For us, launching means commercial availability, it doesn’t mean PowerPoint,” OnePlus co-founder Carl Pei told Reuters.

“We are confident we are going to be one of the first with a commercially available smartphone in Europe,” he said, adding that this would be within the first half of 2019.

Xiaomi Corp, which ranked fifth in smartphone shipments in the last quarter according to IDC, did reveal pricing information along with its first 5G device.

“Xiaomi has fired the starting gun with a $599 price. That will bring tears to the eyes of many other mobile phone makers,” Wood said, adding that many sub-scale makers such as Sony, LG and others could find it tough to make any kind of margin on 5G.

Sony did not show a 5G device, relying instead on its ownership of a major Hollywood studio to release a new line of Xperia phones with a 21:9 display ratio optimized to watch movies and Netflix content.
