As the polar ice caps retreat, polar bears could struggle to survive by the end of this century, a number of university researchers wrote in a study published in the Nature Climate Change journal.The study looked at a number of sub-species of polar bears who live in the arctic and how they have adapted to reduced sea ice from 1979 to 2016. The group of researchers said that all but a few sub-species of polar bears will be able to reproduce and survive given projected conditions by 2100.Polar bears use sea ice to capture seals for food. When sea ice erodes for the summer, polar bears fast. Although polar bears are capable of fasting for months, there are limits to how long the bears can go without food.The researchers examined energy needs of polar bears, and that the amount of time polar bears would fast would lengthen to a point that makes it too challenging to survive and reproduce.While resting female polar bears can generally fast for longer periods of time, reproducing females, males and cubs all require shorter fasting periods, the research found.“Avoiding continued sea-ice decline requires aggressively mitigating greenhouse gas rise,” the researchers wrote, “and our results explicitly describe the costs to polar bears of avoiding that mitigation.”To illustrate how much sea ice is being lost, NOAA is projecting that the arctic could have ice-free summers by 2042.Scientists have long discussed the possibility that polar bears could become nearly extinct by the end of the century. Beyond reducing carbon emissions, proposals have included relocating cubs to areas of the Arctic expected to retain higher levels of sea ice have been proposed.

ATLANTA - In a memo this week, Delta Airlines’ CEO told staff nearly 700 passengers have been placed on the no-fly list in 2020 for refusing to comply with policies requiring masks on planes.This is a sharp increase from the 460 banned passengers the airline reported in October. Delta and other airlines have been adding mask rule-breaking passengers to the no-fly list since early in the pandemic.Delta is not alone, latest numbers from United report about 430 passengers of that airline have been added to the no-fly list for not following their mask policy, and 88 have been banned from JetBlue flights.A Department of Defense study found that masks, combined with airplanes’ air filtration systems, can greatly reduce the risk of transmitting the coronavirus during a flight.While that sounds like a lot of passengers, Delta told Fox News they are flying about 1 million customers per week.In the message to staff Wednesday, Delta’s CEO Ed Bastian thanked employees for taking unpaid leave and manage reductions in hours earlier this year, which helped them be one of the few airlines that avoided involuntary furloughs. Ground workers and headquarters employees were cut to three or four days a week.However, he is now asking employees again to take unpaid leaves of absence to help the company save money, according to the staff memo. Bastian said Wednesday that Delta will need more employees to take unpaid leave “for the foreseeable future.”“I ask everyone to consider whether a voluntary leave makes sense for you and your family,” he said in a memo to employees.About 15,000 Delta employees have already left the airline through buyouts and early retirements, according to the Atlanta Journal Constitution.It's a sign of the deepening slump in air travel with coronavirus cases rising across the country. Delta expects to lose up to million a day on average during the fourth quarter.Delta is also one of the last airlines to block the middle seats on their planes, and says they will do so through March 2021.Unlike American and United, Atlanta-based Delta has avoided furloughs since the pandemic started by convincing thousands of workers to retire early or take unpaid leave.But the air travel recovery seems to be faltering. Passenger traffic rose over Thanksgiving week but has dropped since then. 2327

As screen time becomes a bigger part of students’ lives, preserving their vision is something to keep an eye on.Dr. Lauren Schneider, an ophthalmologist who has been treating patients in New York and Connecticut for six years warned screen time can cause a number of symptoms, including squinting and eye-crossing.“We do know that prolonged near work can place some children at risk for progressive myopia, which is worsening nearsightedness,” Dr. Schneider said.Doctors say tips on preserving your kids' vision during remote learning include making sure they keep a safe distance from their devices — at least 15 inches away from the screen is recommended — having them take screen breaks every 20 minutes and investing in a blue light blocker, which can be put on devices or glasses.“Some of our data suggests blue light emitted from our electronic devices may potentially be harmful long term to the center of the retina,” said Schneider Sunday.As school districts in the tri-state area continue to reopen this fall with full remote or hybrid learning models that include screen-based instruction, eye protection is another safety measure doctors say parents should have their sights on.“We want to make sure that while our students are hard at work which is going to require a lot of time in front of the computer that we’re avoiding unnecessary eye strain," Schneider said.According to medical experts, the full long term impacts on the eyes from remote learning are still being looked at, regular eye exams are highly recommended.For more tips and resources:www.visiontolearn.orgwww.childrenseyefoundation.orgwww.kidshealth.orgThis story was first reported by Jennifer Bisram at PIX11 in New York City, New York. 1726

At least eight nursing home residents have died in Hollywood, Florida, according to the New York Times and NBC News.The deaths may be due to the loss of the home's air-conditioning after Hurricane Irma struck Sunday, according to CNN affiliate WPLG. The causes of death are still being investigated, Hollywood Police Chief Tomas Sanchez said."We are conducting a criminal investigation (and) not ruling anything out at this time," Sanchez said at a press conference Wednesday. 489

As the saying goes, beauty is in the eye of the beholder. And when it comes to appreciating art, that may be more true than ever. It's so subjective and comes down to true appreciation. One woman understands that more than most.To Myrna Hayutin the photos on her gallery wall are more than pictures of the past. She points out some of the art on display.  "This is a limited edition signed by Carl Mydans," Hayutin said. "This is Babe Ruth the last time he put on his uniform."These are works of art."It is history," Hayutin said. "It's just knowledge."And for the last 35 years she's been selling fine art like these pieces, despite the fact that she's legally blind."I anticipate doing this for at least another 10 years," Hayutin said. "As long as my eyesight holds."Hayutin started losing her eyesight when she was eight due to retinitis pigmentosa. And over the years, it's gotten progressively worse."It's like an island," Hayutin said. "As the disease progresses the island gets smaller and smaller now I see through two straws. So you may be standing right here but I am not seeing you. Or if were talking and you move I'll lose you."Still it hasn't affected her love for art or her determination to purse it as a career."It never occurred to me to stop me from doing anything that I really wanted to do," Hayutin said.Hayutin runs a successful international fine art gallery, Gallery M, and recently became an art appraiser."I'm looking at the artwork but honestly thank goodness with my devices I can really zoom in and see them much, much better," Hayutin said.Hayutin said her dog, Gouda, helps her navigate the changes in her eyesight, but what helps most is not focusing on what could happen."I would never have opened the gallery if I was fearful of what would be instead of what was at that time," Hayutin said. "I try to live in today and use the eyesight that I have today."Hayutin said every day is what you make it."There are some days where I'm not as positive as I should be, but I try it," Hauytin said. "I try to get back on that positive I mean because I'm surrounded by all of this gorgeous art and that's very uplifting."  2212
