Amazon’s diligent, computerized know-it-all is the latest technology to enlist in NORAD Tracks Santa, the military-run program that fields phone calls and emails from children around the world eager to ask when Santa will arrive.

Now entering its 62nd year, NORAD Tracks Santa will go live Sunday, with about 1,500 volunteers answering calls and emails at Peterson Air Force Base in Colorado Springs, Colorado. Updates will be posted on social media and at www.noradsanta.org.

And if you have Amazon’s voice-activated Echo device, you can ask Alexa once you enable the function.

Technology has always been at the heart of NORAD Tracks Santa, which got its start in 1955 with an old-school glitch.

 

An advertisement in a Colorado Springs newspaper that year invited kids to call Santa, but it mistakenly listed the number for the hotline at the U.S. Continental Air Defense Command. CONAD, as it was called, had the job of monitoring a vast radar network from a combat operations center in Colorado Springs, searching the skies for any hint of a nuclear attack by the onetime Soviet Union.

Col. Harry Shoup, who was in charge of the operations center, took the first child’s call. Once he figured out what was happening, he played along, he said in a 1999 interview with The Associated Press.

“Here I am saying, ‘Ho, ho, ho, I am Santa,'” said Shoup, who died in 2009. “The crew was looking at me like I had lost it.”

 

He told his staff what was happening and told them to play along, too.

It’s not clear what day the first call came in, but by Friday, Dec. 23 of that first year, the AP reported that CONAD was tracking Santa.

 

“Note to the kiddies,” the story began, under a Colorado Springs dateline. “Santa Claus Friday was assured safe passage into the United States by the Continental Air Defense Command combat operations center here which began plotting his journey from the North Pole early this morning.”

Maybe hoping to soothe a jittery nation, the story added: ”CONAD, Army, Navy and Marine Air Forces will continue to track and guard Santa and his sleigh on his trip to and from the U.S. against possible attack from those who do not believe in Christmas.” That was likely a reference to the officially atheist Soviet Union.

 

The history of the program over the next few years isn’t well documented, said Preston Schlachter, a spokesman for the North American Aerospace Defense Command or NORAD, a U.S.-Canadian command that eventually succeeded CONAD.

 

But TV and radio stations began broadcasting Christmas Eve bulletins from CONAD and NORAD. And by the 1980s, NORAD was soliciting phone calls from children. (The number is now 877-Hi NORAD or 877-446-6723.)

NORAD added its Santa-tracking website in 1997. It went on Facebook, Twitter and YouTube in 2008. Mobile apps came in 2011, Instagram in 2016.

Last year, NORAD Tracks Santa got nearly 154,200 phone calls and drew 10.7 million unique visitors to its website. It snared 1.8 million Facebook followers, 382,000 YouTube views and 177,000 Twitter followers.

 

And this year, Alexa joins the party.

 

Technology and the Santa Claus story have a long but uneasy history together, said Gerry Bowler, a Canadian historian whose books include ”Santa Claus: A Biography” and ”Christmas in the Crosshairs: Two Thousand Years of Denouncing and Defending the World’s Most Celebrated Holiday.”

 

“Every new technology gets tried on Santa,” Bowler said. In the late 1800s, for example, he was depicted chatting with children on the telephone, then a new and wondrous invention.

 

But NORAD’s Santa tracker is one of the only technological upgrades the public has welcomed into the Santa story, Bowler said.

 

“I think that it will be ultimately incompatible with most technology,” Bowler said. “I’m sure of it, because he represents something timeless, and we don’t want him to become dated.

 

“We don’t want him using a fax machine or carrying around one of those 5-pound cellphones,” he said.

Louisiana officials have chosen a sugar cane farm as the next home for residents of a tiny, shrinking island, a move funded with a 2016 federal grant awarded to help relocate communities fleeing the effects of climate change.

Dozens of Isle de Jean Charles residents are to be relocated about 40 miles (64 kilometers) to the northwest, in Terrebonne Parish, Nola.com|The Times-Picayune and The New Orleans Advocate report.

The state is negotiating to purchase the 515-acre (208-hectare) tract, which is closer to stores, schools and health care — and which is less flood-prone than the island, which has been battered by hurricanes and tropical storms.

Louisiana’s Office of Community Development expects to finalize the purchase in the coming weeks.

“Everybody seems to think it’ll be a pretty quick property negotiation,” said Mathew Sanders, the community development office’s resilience program manager.

Construction on the new settlement could begin in late 2018 or early 2019, meaning island residents most likely will have to endure at least one more hurricane season before moving.

Last year, Isle de Jean Charles became the first community in the U.S. to receive federal assistance for a large-scale retreat from the effects of climate change. About $48 million was allotted to purchase land, build homes and move the island’s approximately 80 full-time residents.

Tribe’s area mostly gone

Isle de Jean Charles is home to members of the Biloxi-Chitimacha-Choctaw tribe. It has lost 98 percent of its area since 1955. Causes include erosion, sinking of coastal land, and Mississippi River levees that block replenishing river sediment.

Climate change-triggered sea-level rise is expected eventually to drown the island.

Owned by Acadia Agricultural Holdings, the sugar farm is valued at $19.1 million, but the actual purchase price may be about half that, Sanders said.

Albert Naquin, the tribe’s chief, said he looked at the site two years ago and it was immediately his favorite.

“It’s in the best part of the parish; it’s the highest area,” he said. “I pushed for that one.”

A master plan for the new development being created by the consulting firm CSRS will include not just houses but also community spaces and maybe even features such as crawfish ponds.

“We want to move the people on the island in such a way that the community can sustain itself,” Sanders said. To that end, officials may try to attract some businesses, including retail.

NASA astronaut Bruce McCandless, the first person to fly freely and untethered in space, has died. He was 80.

He was famously photographed in 1984 flying with a hefty spacewalker’s jetpack, alone in the cosmic blackness above a blue Earth. He traveled more than 300 feet away from the space shuttle Challenger during the spacewalk. 

“The iconic photo of Bruce soaring effortlessly in space has inspired generations of Americans to believe that there is no limit to the human potential,” Sen. John McCain said in a statement. The Arizona Republican and McCandless were classmates at the U.S. Naval Academy.

NASA’s Johnson Space Center said Friday that McCandless died Thursday in California. No cause of death was given.

McCandless said he wasn’t nervous about the historic spacewalk.

“I was grossly over-trained. I was just anxious to get out there and fly. I felt very comfortable … It got so cold my teeth were chattering and I was shivering, but that was a very minor thing,” he told the Daily Camera in Boulder, Colorado, in 2006. 

During that flight, McCandless and fellow astronaut Robert L. Stewart pioneered the use of NASA’s backpack device that allowed astronauts walking in space to propel themselves from the shuttle. Stewart became the second person to fly untethered two hours after McCandless.

“I’d been told of the quiet vacuum you experience in space, but with three radio links saying, ‘How’s your oxygen holding out?’ ‘Stay away from the engines!’ ‘When’s my turn?’ it wasn’t that peaceful,” McCandless wrote in the Guardian in 2015.

But he also wrote: ”It was a wonderful feeling, a mix of personal elation and professional pride: it had taken many years to get to that point.”

McCandless was later part of the 1990 shuttle crew that delivered the Hubble Space Telescope to orbit. He also served as the Mission Control capsule communicator in Houston as Neil Armstrong and Buzz Aldrin walked on the moon in 1969.

During his spacewalk, “My wife was at mission control, and there was quite a bit of apprehension,” McCandless wrote. “I wanted to say something similar to Neil when he landed on the moon, so I said, ‘It may have been a small step for Neil, but it’s a heck of a big leap for me.’ That loosened the tension a bit.”

Born in Boston, McCandless graduated from Woodrow Wilson Senior High School in Long Beach, California. He graduated from the Naval Academy and earned master’s degrees in electrical engineering and business administration. 

He was a naval aviator who participated in the Cuban blockade in the 1962 missile crisis. McCandless was selected for astronaut training during the Gemini program, and he was a backup pilot for the first manned Skylab mission in 1973. After leaving NASA, McCandless worked for Lockheed Martin Space Systems in Colorado.

“Bruce served his country with humility and dignity, and encouraged all of us to reach new heights,” McCain said.

Survivors include his wife, Ellen Shields McCandless of Conifer, Colorado, two children and two grandchildren.

One big problem confronts Africa as it tries to predict how its weather patterns will shift in the face of climate change: Almost all the climate models for the continent were created in the United States or Europe.

Now South African climate researcher Francois Engelbrecht has changed that by developing a climate model for Africa, in Africa.

The model aims to “generate reliable projections of future climate change over Africa,” said Engelbrecht, the chief researcher for climate studies, modeling and environmental health at South Africa’s Council for Scientific and Industrial Research.

Those projections include figuring out which areas will get more or less rainfall — “a key to adapting agriculture successfully” — or looking at where African grasslands might give way to thickets as more carbon dioxide in the atmosphere drives the growth of trees.

“We know that climate is changing, risks are changing, including changes in the risk of heat waves, flooding, drought, tropical cyclones, changes in growing seasons [and] rising temperatures,” said Rachel James, a visiting climate researcher at the University of Cape Town.

“People everywhere will need to adapt to these changing conditions in the years and decades to come,” she told Reuters.

“The problem is that we don’t know exactly what will happen in any one location. It’s challenging to predict which areas might get more rainfall and which might get less.”

More detail

The new African-built climate model aims to generate much more detailed and place-specific projections, to give decision makers the information they need to prepare for coming changes.

It responds, in part, to the Intergovernmental Panel on Climate Change noting in 2014 that Africa was the only region of the world in which climate forecasts had not improved in recent years.

Developed in collaboration with Australia, the model will look at things such as how El Nino patterns are likely to affect Africa in the future and how African monsoons may shift, Engelbrecht said.

Africa has a lot of expertise on its ecosystems, regional oceans, and climate, but this knowledge has not been built into models up to now, he said.

Models developed by northern hemisphere countries have tended to focus more on areas of northern interest, such as the Arctic, where sea ice is fast disappearing, he said.

And global models that include Africa generally are not specific enough to be helpful on the ground in a particular country or region, said Neville Sweijd, head of the South Africa-based Alliance for Collaboration on Climate and Earth Systems Science.

“All models are not complete representations of reality and have to be tested for sensitivity to various features and phenomena,” he said, including the direction of winds.

James noted that “climates in Africa are particularly challenging to model” because of the influence of local events such as key thunderstorms, “which occur on finer scales than the models can resolve,” she said.

A ‘game changer’

Jean-Pierre Roux, who manages the Future Climate for Africa project, an effort, backed by UK aid, to improve climate information and resilience on the continent, said he worries that weak climate information and weather information services that do not meet the needs of vulnerable communities could hurt millions in Africa.

Having African scientists involved in climate information efforts is important as African researchers naturally have more expertise on local and regional weather and climate in many cases, he said.

Also, “it gives a better chance for African priorities to shape the research agenda and leaves behind a legacy in terms of improved African capacity to conduct research,” he said.

African climate scientists say they are also worried that the continent does not yet have enough climate scientists to collaborate with other experts globally on models and other work.

“A lot of model application work is being done in Africa, but not by Africans or at African institutions. That disempowers African intellectual development in this field,” Sweijd told Reuters.

Engelbrecht sees the development of his model as a chance to build skills in everything from climate science to high-performance computing.

“It is a game changer in enhancing our human capacity in the climate and earth sciences,” he said.

A nutritional survey of Rohingya refugee children at a camp in Cox’s Bazar, Bangladesh, found high rates of malnutrition and other debilitating, life-threatening health problems.

UNICEF spokesman Christophe Boulierac calls the survey findings alarming, saying they indicate thousands of Rohingya refugee children are facing a public health crisis.

“Up to 25 percent of children under the age of five are suffering from acute malnutrition,” Boulierac said. “This is much more than the WHO emergency threshold of 15 percent. … Half of the children, nearly half of them, have anemia. Up to 40 percent of them have diarrhea and up to 60 percent of them have acute respiratory infections.” 

UNICEF conducted three surveys between October 22 and November 27 of more than 1,700 newly arrived refugee children from Myanmar in refugee camps and makeshift settlements in Cox’s Bazar.

Fewer than 16 percent of children in the camps are eating a diet considered barely acceptable and sufficient for their growth and development, Boulierac says.

UNICEF has set up 22 outpatient treatment centers where refugee children can receive special nutritional food and clean water.

An estimated 645,000 Rohingya have fled persecution and violence in Myanmar since the end of August. More than half are children.

Scott Judd trained his camera lens on the white dot in the distance. As he moved up the Lake Michigan shoreline, the speck on a breakwater came into view and took his breath away: it was a snowy owl, thousands of miles from its Arctic home.

“It was an amazing sight,” said Judd, a Chicago IT consultant. “It’s almost like they’re from another world. They captivate people in a way that other birds don’t.”

The large white raptors have descended on the Great Lakes region and northeastern U.S. in huge numbers in recent weeks, hanging out at airports, in farm fields, on light poles and along beaches, to the delight of bird lovers.

But for researchers, this winter’s mass migration of the owls from their breeding grounds above the Arctic Circle is serious business.

It’s a chance to trap and fit some of the visitors with tiny transmitters to help track them around the globe and study a long-misunderstood species whose numbers likely are far fewer than previously thought, researchers say.

“There is still a lot that we don’t know about them … but we aim to answer the questions in the next few years,” said Canadian biologist Jean-Francois Therrien, a senior researcher at Hawk Mountain Sanctuary in Pennsylvania.

The solar-powered transmitters can last for years, collecting information such as latitude, longitude, flight speed and air temperature that is downloaded to a server when the birds fly into range of a cell tower.

The use of transmitters, which intensified during the last North American mass migration in winter 2013-14, already has yielded big surprises.

Instead of 300,000 snowy owls worldwide, as long believed, researchers say the population likely is closer to 30,000 or fewer. The previous estimate was based on how many might be able to breed in a given area.

That calculation was made assuming snowy owls acted like other birds, favoring fixed nesting and wintering sites. But researchers discovered the owls are nomads, often nesting or wintering thousands of miles from previous locations.

The miscalculation doesn’t necessarily mean snowy owls, which can grow to about 2 feet long (60 centimeters long) with 5-foot (1.5-meter) wingspans, are in decline. Scientists simply don’t know because they never had an accurate starting point.

This month, snowy owls were listed as vulnerable — one step away from endangered — by the International Union for Conservation of Nature. They’re protected in the U.S. under the Migratory Bird Act.

This year’s mass migration is a bit of good news. Researchers once thought these so-called “irruptions” signaled a lack of prey in the Arctic, but now believe the opposite: Breeding owls feed on lemmings, a rodent that lives under Arctic snowpack and whose population surges about every three or four years. More lemmings means the owl population explodes— and that more birds than usual will winter in places people can see them.

But researchers worry that climate change will affect the owl population because lemmings are exceptionally sensitive to even small temperature changes.

Lemmings “depend on deep, fluffy, thick layers of insulating snow” to breed successfully, said Scott Weidensaul, director at Project SNOWstorm, an owl-tracking group whose volunteers have put transmitters on more than 50 snowy owls in the past four years .

The snowy owl population collapsed in Norway and Sweden in the mid-1990s, all but vanishing there for almost two decades before reappearing at lower numbers, experts said. In Greenland, where the population collapsed in the late 1990s, researchers found a few nests in 2011 and 2012 after six years with no recorded nests, but owls didn’t come back in 2016 or 2017, when lemmings should have been peaking.

The National Oceanic and Atmospheric Administration reported this month that the far northern Arctic is warming twice as fast as the rest of the globe.

But it’s tough to assess lemming population trends in remote areas. Although researchers hope to enlist native villagers to help, it’s mostly up to owls with transmitters for now.

Snowy owls somehow seem to find lemmings even if they are thousands of miles from where their population last peaked, Therrien said.

“They look around the Arctic,” he said. “The movement is amazing to watch on a map: There are no straight lines. They’re zigzagging.”

Norman Smith, a snowy owl expert with Mass Audubon in Massachusetts, said he’s heartened that many independent researchers worldwide joined forces to share information on snowy owls.

“It’s amazing what we’ve learned, but we need a bigger database of birds,” said Smith, who has been trapping owls at Boston’s Logan International Airport for more than 35 years and fits them with a leg band or transmitter before letting them go. He put a satellite tracker on an owl for the first time in 2000, proving that they could make it back to the Arctic.

Last week, Smith released a young female on a barrier beach along the Atlantic Ocean. It flew south, then circled back and flew overhead. As he drove over a bridge to the mainland, the owl was sitting on a post, surveying its new winter home.

In a remarkably strong show of consumer demand, nearly 9 million people signed up for “Obamacare” next year, as government numbers out Thursday proved predictions of its collapse wrong yet again.

 

The Centers for Medicare and Medicaid Services said more than 8.8 million people have signed up in the 39 states served by the federal HealthCare.gov website.

 

That compares to 9.2 million last year in the same states – or 96 percent of the previous total.

 

The level exceeds what experts thought was possible after another year of political battles over the Affordable Care Act, not to mention market problems like rising premiums and insurer exits. On top of that, the Trump administration cut enrollment season in half, slashed the ad budget, terminated major payments to insurers, and scaled back grants for consumer counselors.

 

“This level of enrollment is truly remarkable, especially given the headwinds faced by the program,” said Larry Levitt of the nonpartisan Kaiser Family Foundation.

 

President Donald Trump insistently predicted “Obamacare” would implode as he pursued unsuccessful efforts to repeal it in Congress. This week he incorrectly declared the GOP tax bill had essentially repealed it.

 

Despite all that, more than 1 million new customers signed up last week, ahead of a December 15 deadline for HealthCare.gov. That’s a sign of solid interest in the program, which offers subsidized private health insurance to people who don’t have access to job-based coverage.

 

It’s possible that final HealthCare.gov numbers could end up somewhat higher than reported Thursday, partly because late sign-ups in the Midwest and the West have yet to be added in.

 

The nationwide enrollment total won’t be known for weeks, since some states running their own health insurance markets – or exchanges – continue signing up customers through January.

 

Total national enrollment could wind up near last year’s final number of 12.2 million.

 

“We know anecdotally that many state exchanges are running ahead of last year, (and) we could actually make up the national enrollment deficit with higher state-run exchange enrollment,” said Chris Sloan of the consulting firm Avalere Health.

 

Among the HealthCare.gov states, Florida led in enrollments, with 1.7 million people so far. Texas was next, with 1.1 million. Sign-ups for those states could rise, since a deadline extension is available for people in hurricane-affected areas.

 

In Austin, Texas, a nonprofit group that helps low-income working people surpassed its enrollments for last year, and then some. Foundation Communities signed up 5,323 people this year, or about 20 percent more than last year.

 

‘Obamacare is working’

Health insurance program director Elizabeth Colvin credited squads of volunteers who helped steer consumers through a sign-up process that includes having to estimate their income for next year and other challenges.

 

“The number that came out today proves that Obamacare is working,” said Colvin.

 

Lori Lodes, a former Obama administration official who once helped direct the enrollment campaign, said it’s likely that last week saw the biggest number of sign-ups in the program’s history.

 

That’s certain to lead to more criticism of the Trump administration for shortening open enrollment and other actions that Democrats call “sabotage.”

 

“The American people surged to defend this historic law from the cruelty of Trumpcare, and they enrolled at a record pace in quality, affordable health coverage on HealthCare.gov,” said House Democratic leader Nancy Pelosi of California.

 

However, the administration also took other less noticed steps to facilitate enrollment, such as creating an easier path for insurers and brokers to sign up customers.

 

The strong numbers for HealthCare.gov came a day after Trump proclaimed that the GOP tax bill “essentially repealed Obamacare.”

 

But the tax overhaul only repealed the health law’s fines on people who don’t carry health insurance, starting in 2019. Other major elements of former president Barack Obama’s law remain in place, including its Medicaid expansion tailored to low-income adults, protections for people with pre-existing medical conditions, subsidies to help consumers pay their premiums, and requirements that insurers cover “essential” health benefits.

 

First word of the enrollment numbers came via Twitter from Seema Verma, head of the Centers for Medicare and Medicaid Services.

 

She struck an upbeat tone:

 

“We take pride in providing great customer service,” she wrote, congratulating her agency on “the smoothest experience for consumers to date.”

 

In an interview Thursday with The Associated Press, Senate Majority Leader Mitch McConnell, R-Kentucky, indicated he’s skeptical at best about revisiting botched efforts to dismantle the health care law.

 

Bipartisan legislation to shore up insurance markets is pending before the Senate, but its fate is also uncertain.

U.S. deaths from drug overdoses skyrocketed 21 percent last year, and for the second straight year dragged down how long Americans are expected to live.

The government figures released Thursday put drug deaths at 63,600, up from about 52,000 in 2015. For the first time, the powerful painkiller fentanyl and its close opioid cousins played a bigger role in the deaths than any other legal or illegal drug, surpassing prescription pain pills and heroin.

“This is urgent and deadly,” said Dr. Brenda Fitzgerald, director of the Centers for Disease Control and Prevention. The opioid epidemic “clearly has a huge impact on our entire society.”

​Opioids behind two-thirds of deaths

Two-thirds of last year’s drug deaths, about 42,000, involved opioids, a category that includes heroin, methadone, prescription pain pills like OxyContin, and fentanyl. Fatal overdoses that involved fentanyl and fentanyl-like drugs doubled in one year, to more than 19,000, mostly from illegally made pills or powder, which is often mixed with heroin or other drugs.

Heroin was tied to 15,500 deaths and prescription painkillers to 14,500 deaths. The balance of the overdose deaths involved sedatives, cocaine and methamphetamines. More than one drug is often involved in an overdose death.

The highest drug death rates were in ages 25 to 54.

Preliminary 2017 figures show the rise in overdose deaths continuing.

​Life expectancy 78 years, 7 months

The drug deaths weigh into CDC’s annual calculation of the average time a person is expected to live. The life expectancy figure is based on the year of their birth, current death trends and other factors. For decades, it was on the upswing, rising a few months nearly every year. But last year marked the first time in more than a half century that U.S. life expectancy fell two consecutive years.

A baby born last year in the U.S. is expected to live about 78 years and 7 months, on average, the CDC said. An American born in 2015 was expected to live about a month longer and one born in 2014 about two months longer than that.

The dip in 2015 was blamed on drug deaths and an unusual upturn in the death rate for the nation’s leading killer, heart disease. Typically, life expectancy goes back up after a one-year decline, said Robert Anderson, who oversees the CDC’s death statistics. The last time there was a two-year drop was 1962-1963. It also happened twice in the 1920s.

“If we don’t get a handle on this,” he said, “we could very well see a third year in a row. With no end in sight.”

Flu pandemic

A three-year decline happened in 1916, 1917 and 1918, which included the worst flu pandemic in modern history.

Overall, there were more than 2.7 million U.S. deaths in 2016, or about 32,000 more than the previous year. It was the most deaths in a single year since the government has been counting. That partly reflects the nation’s growing and aging population. But death rates last year continued to go down for people who are 65 and older while going up for all younger adults, those most affected by the opioid epidemic.

The CDC also reported:

• West Virginia continued to be the state with highest drug overdose death rate, with a rate of 52 deaths per 100,000 state residents in 2016. Ohio and New Hampshire were next, both at about 39 per 100,000.

• Life expectancy for men decreased, but it held steady for women. That increased the gender gap to five years; about 76 for men and 81 for women.

• U.S. death rates decreased for seven of the 10 leading causes of death, but rose for suicide, Alzheimer’s disease and for a category called unintentional injuries, which includes drug overdoses.

• Accidental injuries displaced chronic lower respiratory diseases to become the nation’s third leading cause of death. Contributing were increases in deaths from car crashes and falls.

• Gun deaths rose for a second year, to nearly 39,000. They had been hovering around 33,500 deaths a few years ago.

The United States ranks below dozens of other high-income countries in life expectancy, according to the World Bank. Highest is Japan, at nearly 84 years.

“The fact that U.S. has basically stagnated over the past seven years, and now we’re seeing small declines, is a real sign that the U.S. is doing badly,” said Jessica Ho, a University of Southern California researcher who studies death trends.

Scientists warn a campaign to eradicate polio in central Africa is falling short because of upheaval in the Lake Chad Basin area, where the Boko Haram militant group remains active.  On the positive side, on country – Gabon – has been declared polio-free.

Professor Rose Leke, who heads the Africa Regional Certification Commission for polio eradication, says Central Africa has seen no cases of polio in the past 15 months.  But, she adds, scientists cannot be sure the polio virus has been eradicated in the region.

Leke says medical teams find it difficult getting access to conflict zones in Mali, the Central African Republic, the Democratic Republic of Congo (DRC) and parts of Cameroon, Chad, Niger and Nigeria affected by the Boko Haram insurgency.

“DRC has circulating polio viruses, so many of them.  We are worried about the country and so we have specific recommendations also for DRC and for all the others. We are still very concerned about the Lake Chad basin area, the Borno [state in Nigeria] area where we do not know what is happening there.  I think that is a concern for the entire world,” she said.

Leke says polio cases have decreased by more than 99 percent in the past 30 years, from an estimated 350,000 per year to just 37 reported cases in 2016.

She says as a result of the global effort to eradicate the disease, more than 16 million people have been saved from paralysis.

According to the United Nations, once a case of polio is recorded, it takes three years of no other case to declare the zone polio-free.  Gabon recently reached that goal.

Gabon’s neighbor Cameroon has attained the status of “non-polio exporting country,” but is still considered a high-risk nation like other African states with an influx of refugees from conflict zones that health care workers mostly avoid.

But Alim Hayatou, Cameroon’s secretary of state in the ministry of health, says the country is also on track to be polio-free.

He says they have prepared an ambitious plan to make sure Cameroon eliminates polio by 2019.

Central African states have organized numerous inoculation campaigns, but more than 15 percent of children in the region remain unvaccinated due to cultural resistance, conflicts and illiteracy.

A survey by the U.N. refugee agency reveals heightened worries by the Rohingya refugee population in Cox’s Bazar, Bangladesh over their health and safety.

It has been nearly four months since the mass exodus of Rohingya refugees began from Myanmar into Cox’s Bazar, Bangladesh. More than 645,000 Rohingya who escaped violence and persecution in Myanmar are living in squalid, overcrowded settlements.  

A survey by the U.N. refugee agency and 13 other organizations finds the refugees have developed strong support networks to help them cope with their difficulties.

UNHCR spokesman Andrej Mahecic says the refugees have many worries. They express concern about their safety, considering their weak shelter accommodations and poor lighting at night.

“Access to sanitation is still insufficient, leading sometimes to long queues for latrines,” said Mahecic. “Women and girls are anxious about the shortage of private bathing spaces, forcing some to wash outside their shelters in early morning hours.”

The survey finds some children have to walk long distances to fetch water and firewood, a situation that can put them at risk. Mahecic says both parents and children want access to education and more safe places for children to play. He says health services also are a major concern.

“Increased mental health support for those who have witnessed the killings or suffered torture or rape remains crucially needed,” said Mahecic. “Refugees cite continued feelings of depression and rejection, especially among the elderly and disabled. Many young people are worried about their uncertain future.” 

Mahecic says the UNHCR will use the survey findings to improve its protection and assistance programs for the Rohingya in the coming year. He says the agency already has begun providing alternatives to firewood to address child labor and environmental concerns.

He says efforts also are under way to improve the hygiene and sanitary conditions for women and girls and to provide more child-friendly spaces where boys and girls can play in safety. Children account for more than half of the refugee population.

Health officials say the refugees are extremely vulnerable to diseases as they have low vaccination coverage and are living in congested, unsanitary settlements that are breeding grounds for infectious diseases.

While 2017 may only emerge as the third warmest year on record, scientists predict it will beat out the competition for warmest year without a warming El Nino. These record setting years concern those who see this as a sure sign that climate change is happening at a quickened pace.

The WMO says the overall long-term warming trend since the late 1970s is worrying and cannot be ignored. The United Nations agency says rising temperatures are ushering in more extreme weather with huge socioeconomic impact.

WMO spokeswoman Claire Nullis says the warming conditions prevailing over both the Arctic and the Antarctic are very alarming. She says the Arctic is warming at about twice the rate of the global temperature increase.

“We are very, very concerned about the rate of warming in the Arctic,” she said. “There was an Arctic Report Card released last week. It said while 2017 saw fewer records shattered than in 2016, the Arctic shows no sign of returning to the reliably frozen region it was decades ago.”

​The Arctic Report Card is a peer-reviewed report that brings together the work of 85 scientists from 12 nations.

WMO notes warmer than average temperatures dominated across much of the world’s land and ocean surfaces during November. It says the most notable temperature rises were across the Northern Hemisphere.

For example, it reports temperatures in northern Canada and northwestern Alaska were two degrees centigrade above the average, indicating a very pronounced warming at the Arctic.

The Environmental Protection Agency says an internal task force appointed to revamp how the nation’s most polluted sites are cleaned up generated no record of its deliberations.

EPA Administrator Scott Pruitt in May announced the creation of a Superfund Task Force that he said would reprioritize and streamline procedures for remediating more than 1,300 sites. Pruitt, the former attorney general of Oklahoma, appointed a political supporter from his home state with no experience in pollution cleanups to lead the group.

The task force in June issued a nearly three-dozen page report containing 42 detailed recommendations, all of which Pruitt immediately adopted. The advocacy group Public Employees for Environmental Responsibility, known as PEER, quickly filed a Freedom of Information Act request seeking a long list of documents related to the development of Pruitt’s plan.

After EPA didn’t immediately release any records, PEER sued.

Now, nearly six months after the task force released its report, a lawyer for EPA has written PEER to say that the task force had no agenda for its meetings, kept no minutes and used no reference materials.

Further, there was no written criteria for selecting the 107 EPA employees the agency says served on the task force or background materials distributed to them during the deliberative process for creating the recommendations.

According to EPA, the task force also created no work product other than its final report.

“Pruitt’s plan for cleaning up toxic sites was apparently immaculately conceived, without the usual trappings of human parentage,” said Jeff Ruch, the executive direction of PEER. “It stretches credulity that 107 EPA staff members with no agenda or reference materials somehow wrote an intricate plan in 30 days.”

The task force was led by Albert “Kell” Kelly, whom Pruitt hired at EPA as a senior adviser. Kelly was previously the chairman of Tulsa-based SpiritBank, where he worked as an executive for 34 years.

The Associated Press reported in August that Kelly was barred by the Federal Deposit Insurance Corporation from working for any U.S. financial institution after officials determined he violated laws or regulations, leading to a financial loss for his bank. The FDIC’s order didn’t detail what Kelly is alleged to have done. Without admitting wrongdoing, he agreed to pay a $125,000 penalty.

In the universe, particularly in our galaxy, there are a great number of multiple-stellar systems where two or more stars rotate around each other. In many of these systems, the stars collide – a phenomenon that has been familiar to astronomers for a long time. But scientists say a collision that happened almost two thousand years ago will soon be able to be seen with the naked eye. VOA’s Aram Vanetsyan has more.

A new study has dashed hopes that people may be able to protect themselves from dementia through medicine, diet or exercise.

“To put it simply, all evidence indicates that there is no magic bullet,” Dr. Eric Larson wrote in the Annals of Internal Medicine.

The study outlined in the medical journal looked at four types of intervention to try to prevent dementia — prescription drugs, exercise, cognitive training, and nonprescription vitamins and supplements.

Researchers found none worked.

The Lancet, a British medical journal, ​reported earlier this year that about one-third of dementia cases could be linked to such conditions as cigarette smoking, high blood pressure, obesity, a lack of exercise and depression.

While Larson said there was no simple answer to the prevention of dementia, he highly recommended a commonsense, healthful lifestyle that may help delay the disease. It would involve exercising regularly, refraining from smoking, eating a healthful diet and taking part in activities that stimulate the brain.

Like a friendly Pied Piper, the violinist keeps up a toe-tapping beat as dancers weave through busy hospital hallways and into the chemotherapy unit, patients looking up in surprised delight. Upstairs, a cellist plays an Irish folk tune for a patient in intensive care.

Music increasingly is becoming a part of patient care, although it’s still pretty unusual to see roving performers captivating entire wards, as they did at MedStar Georgetown University Hospital one recent fall morning.

“It takes them away for just a few minutes to some other place where they don’t have to think about what’s going on,” said cellist Martha Vance after playing for a patient isolated to avoid spreading infection.

The challenge: harnessing music to do more than comfort the sick. Now, moving beyond programs like Georgetown’s, the National Institutes of Health is bringing together musicians, music therapists and neuroscientists to tap into the brain’s circuitry and figure out how.

“The brain is able to compensate for other deficits sometimes by using music to communicate,” said NIH Director Dr. Francis Collins, a geneticist who also plays a mean guitar.

To turn that ability into a successful therapy, “it would be a really good thing to know which parts of the brain are still intact to be called into action — to know the circuits well enough to know the backup plan,” Collins added.

Scientists aren’t starting from scratch. Learning to play an instrument, for example, sharpens how the brain processes sound and can improve children’s reading and other school skills. Stroke survivors who can’t speak sometimes can sing, and music therapy can help them retrain brain pathways to communicate. Similarly, Parkinson’s patients sometimes walk better to the right beat.

Scientific explanation

But what’s missing is rigorous science to better understand how either listening to or creating music might improve health in a range of other ways — research into how the brain processes music that NIH is beginning to fund.

“The water is wide, I cannot cross over,” well-known soprano Renee Fleming belted out, not from a concert stage but from inside an MRI machine at the NIH campus.

The opera star, who partnered with Collins to start the Sound Health initiative, spent two hours in the scanner to help researchers tease out what brain activity is key for singing. How? First, Fleming spoke the lyrics. Then she sang them. Finally, she imagined singing them.

“We’re trying to understand the brain not just so we can address mental disorders or diseases or injuries, but also so we can understand what happens when a brain’s working right and what happens when it’s performing at a really high level,” said NIH researcher David Jangraw, who shared the MRI data with The Associated Press.

To Jangraw’s surprise, several brain regions were more active when Fleming imagined singing than when she actually sang, including the brain’s emotion center and areas involved with motion and vision. One theory: It took more mental effort to keep track of where she was in the song, and to maintain its emotion, without auditory feedback.

Fleming put it more simply: “I’m skilled at singing so I didn’t have to think about it quite so much,” she told a spring workshop at the John F. Kennedy Center for the Performing Arts, where she is an artistic adviser.

Indeed, Jangraw notes a saying in neuroscience: Neurons that fire together, wire together. Brain cells communicate by firing messages to each other through junctions called synapses. Cells that regularly connect — for example, when a musician practices — strengthen bonds into circuitry that forms an efficient network for, in Fleming’s case, singing.

But that’s a healthy brain. In North Carolina, a neuroscientist and a dance professor are starting an improvisational dance class for Alzheimer’s to tell whether music and movement enhance a diseased brain’s neural networks.

Well before memory loss becomes severe, Alzheimer’s patients can experience apathy, depression, and gait and balance problems as the brain’s synaptic connections begin to falter. The NIH-funded study at Wake Forest University will randomly assign such patients to the improvisation class — to dance playfully without having to remember choreography — or to other interventions.

What will scans show?

The test: If quality-of-life symptoms improve, will MRI scans show correlating strengthening of neural networks that govern gait or social engagement?

With senior centers increasingly touting arts programs, “having a deeper understanding of how these things are affecting our biology can help us understand how to leverage resources already in our community,” noted Wake Forest lead researcher Christina Hugenschmidt.

Proof may be tough. An international music therapy study failed to significantly help children with autism, the Journal of the American Medical Association recently reported, contradicting earlier promising findings. But experts cited challenges with the study and called for additional research.

Unlike music therapy, which works one on one toward individual outcomes, the arts and humanities program at Georgetown Lombardi Comprehensive Cancer Center lets musicians-in-residence play throughout the hospital. Palliative care nurses often seek Vance, the cellist, for patients anxious or in pain. She may watch monitors, matching a tune’s tempo to heart rate and then gradually slowing. Sometimes she plays for the dying, choosing a gently arrhythmic background and never a song that might be familiar.

Julia Langley, who directs Georgetown’s program, wants research into the type and dose of music for different health situations: “If we can study the arts in the same way that science studies medication and other therapeutics, I think we will be doing so much good.”

The U.S. Environmental Protection Agency on Monday issued a notice that it wants public input for a possible replacement of Obama-era regulations on carbon dioxide emissions from power plants that the agency is repealing.

The agency’s advance notice kicks off a 60-day comment period on “specific topics for the Agency to consider in developing any subsequent proposed rule,” according to an EPA release.

The move comes after the agency proposed in October to repeal the Obama administration’s Clean Power Plan, a collection of emissions standards for U.S. states intended to reduce pollution from power plants – the largest emitters of greenhouse gases – by 32 percent below 2005 levels by 2030.

“The EPA sets out and requests comment on the roles, responsibilities, and limitations of the federal government, state governments, and regulated entities in developing and implementing such a rule, and the EPA solicits information regarding the appropriate scope of such a rule and associated technologies and approaches,” the notice says.

When EPA Administrator Scott Pruitt first announced he planned to repeal the Clean Power Plan, it was not clear whether the agency intended to replace it. At his first congressional hearing earlier this month, Pruitt said he planned to replace it.

The notice specifically asks for comment on measures to reduce carbon emissions directly at a power plant.

Obama’s Clean Power Plan allowed states to reduce power plant emissions by using a series of different measures across their plant fleets, which some industry groups said went beyond the scope of the federal Clean Air Act.

The EPA is also asking for comment on the role and responsibility of states in regulating power plants for greenhouse gas emissions.

The notice said EPA also wants to hear from states including California and New York, which already have programs to reduce emissions from power plants, to see how their programs could interact with a replacement rule.

Environmental groups, who plan to continue challenging the agency’s moves against the CPP in court, said on Monday the agency is not serious about offering a valid replacement to the Obama-era regulation.

“A weaker replacement of the Clean Power Plan is a non-starter. Americans – who depend on EPA to protect their health and climate – deserve real solutions, not scams,” said David Doniger, director of climate and clean air at the Natural Resources Defense Council.
