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.

As mixed messages continue regarding face coverings, Mississippi became the first state to lift a statewide mask mandate. Cities and towns can now put their own rules in place.The governor said the facts and data still show masks work, and the state is still requiring them at certain events, including the state fair that starts this week.“I suspect Mississippi will see an increase in cases if people stop wearing face coverings,” said Dr. Amesh Adalja with the Johns Hopkins University Center for Health Security.Infectious disease experts remind people just because an order may be lifted, doesn't mean they should stop wearing masks.“We have to have an effective vaccine to prevent people from getting infected as well as prevent them from getting severe disease, that we had adequate testing capacity so people could know their status and wouldn't go out into public if they were positive,” said Adalja. “I think short of that, masks are going to be one tool that we have to continue to use and many people are going to get accustomed to masks and they're going to realize that masks also likely have some impact on other respiratory viruses, so we may see mask wearing much more common in the United States, similar to what it is in other Asian countries, because of the value people are gaining from them.”New research on homemade cloth masks found they expel invisible cotton fibers into the air. It’s unknown if those fibers can carry infectious viral particles, which drives home the point of washing any cloth facial coverings. Make sure you do that regularly. 1580

AURORA, Colo. -- When Amy and Marco Becerra adopted a 3-year-old Peruvian girl last April, they had no idea what kind of ordeal it would be to get approval for her to stay in the U.S.The Aurora couple, both U.S. citizens, had been living in Peru and had been taking care of their adopted daughter Angela since she was 12 days old.After getting clearance from the Peruvian courts to adopt Angela, they began planning to come back to the U.S. But Angela's application for immigration kept getting delayed."We had been reaching out to USCIS (United States Citizenship & Immigration Services) for over a year, asking and sometimes begging, and sometimes crying for help," Amy Becerra said. She said the people answering USCIS's 1-800 number would simply recite what was on their website, and that some of the information conflicted with information on another government agency website.Tourist VisaThe Becerras brought Angela to Colorado on a tourist visa, and continued their efforts to get Immigration officials to grant her citizenship.Earlier this month, they learned their request had been denied.It came as a shock."No one can believe that would happen to two U.S. Citizens," Amy Becerra said.The couple went public with their plight.Congressman gets involvedRepublican Colorado Congressman Mike Coffman then got involved. "What a broken immigration system that would even think about deporting a 4-year-old," Coffman said.On Thursday, Coffman held a news conference to announce that USCIS had reversed course."They said they re-opened it due to the complexities of the case," he said, adding that he believes the agency bowed to public pressure which was a result of all of Amy Becerra's hard work.The Becerras will now be able to reapply for Angela's citizenship papers.The Congressman's Communications Director Daniel Bucheli said it should be automatic since both parents are U.S. Citizens.He said Coffman offered to pay the ,040 application fee out of his own personal account."I feel very grateful," Marco Becerra said. "Another big door is open for my family. I'm feeling no more stress."Now, 4-year-old Angela can grow up knowing that her home is in Aurora, Colorado. 2301

At 102 years old, Bea Lumpkin hasn't missed voting in a presidential election in 80 years. And even though COVID-19 is putting older Americans at risk ahead of the 2020 election, Lumpkin would not be denied her right to vote.The retired Chicago teacher donned full personal protective equipment — including a hazmat hood and gloves — so she could deliver her ballot to a nearby mailbox."If Bea can do it, anyone can do it. Vote!" the Chicago Teacher's Union said in an Instagram post.Lumpkin said she hopes her vote inspires others to hit the polls this fall — whether by mail, early or in-person."That's why I had my grandson take a photo of me, because if I could come out at the age of 102 and face a pandemic [to vote], nobody should have an excuse," she said to "Good Morning America." "I think that in this election more than any other that I've taken part in, the only way we can answer it is for the people to come out and vote and stay active to a degree we've never seen before." 997
