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 novel coronavirus cases soar across the country, states are struggling to keep up with the demand for testing. Some states are reporting big backlogs and difficulty getting tests.“We need to actually continue doing a bunch of work in America to figure out additional approaches to do testing,” said Dr. Bob Kocher.Dr. Kocher is the former co-chair of California's Testing Task Force. The state formed the team back in March to figure out how to get everyone tested. Back then, they were struggling to do 2,000 tests a day. Now, they're doing more than 100,000 a day.“California, and most states, had giant shortages of the world’s most expensive Q-tips, called swabs, that you need to collect the samples and the people who make them couldn’t make more of them,” Dr. Kocher explained. “We worked with companies to 3-D print them and to source those from other places in the world and buy them and bring them to California.”They worked to find labs that could do high-capacity testing and expanded the number of testing sites. But as cases increased across the state and nation, five months into the pandemic, testing turnaround time is an issue.“It’s something I’m concerned about as demand for testing grows everywhere in the country and on the earth, the labs are going to sporadically have backlogs, and over time, they could have backlogs because it’s hard to make more supply of the test,” Dr. Kocher said.Dr. Kocher says it depends on where the test is sent. Some labs have backlogs and it’s a logistics issue. If the lab your test site is using is in another part of the country, it'll likely take longer to get results.In a statement, Quest Diagnostics said, "We are grappling with surging demand that is outpacing capacity. This is due to surging cases of COVID-19 across much of the United States, particularly the West, Southwest and South. We have a prioritization program to help direct testing to patients most in need. Our turnaround time for priority one patients is 1 day on average."In a recent press conference, California's Health and Human Services Agency Secretary Dr. Mark Ghaly said supply chain challenges forced the state to prioritize who gets tested first.“Surges across the nation have created challenges of getting tests processed, not just collected, and ensuring our guidelines not only say who needs to be tested but give guidance to labs on which specimens to process first,” Dr. Kocher said.Right now, priority means those who are hospitalized, healthcare workers, first responders, social service employees, those who are 65 and older and those with chronic medical conditions. But, we simply need more tests.“The challenge with COVID-19 is that each person infects two, three more people and that leads to exponential growth of people who are infected and exponential growth in demand for testing,” Dr. Kocher said. “The companies who manufacture tests have been extraordinary scaling up their capacity to manufacture tests they can grow them by 10, 30 maybe a 100 percent, but the demand for COVID testing is growing 1,000 percent.”The American Clinical Laboratory Association which represents Quest and other labs released a statement saying many labs are getting more test orders than they're able to process in a single day.In a statement, the company said, "We can’t do it alone. Laboratories, diagnostic manufacturers, ordering providers, public health officials, states and importantly, the federal government – including Congress and the Administration – all have a role to play in addressing the challenges hampering our nation’s response to this public health crisis."The test, Dr. Kocher says, only tells you if you're infectious at the time you were tested. It's yet another hurdle for states to tackle."So, we need to figure out what is the mechanism to test people at the right frequency to make us all safe and fell confident in going to work, school, nursing home or being an essential worker,” he said. “It’s really important.”Figuring out what that looks like means looking at new technologies, getting the government involved and working on our manufacturing sector so we have more tests and fewer logistical problems as we consistently try to keep up with the virus that seems to be one step ahead of us all. 4276

As our country works to rebound, we're helping you manage the pressure as the pandemic is shifting caregiving responsibilities.More millennials are taking on this responsibility now. They're becoming a greater percentage of what's known as the "sandwich generation." Those are people who are caring for both their own kids and their aging parents.New numbers from insurance company New York Life show a third of millennials are doing this now.“We're not replacing the typical 49-year-old woman who's the family caregiver. She's still doing it, but the need is so great that more and more young people are called into the role as well and that's going to continue well after the COVID pandemic,” said John Schall, CEO of the Caregiver Action Network.Nearly half of the so-called "sandwich generation" expect to be a caregiver in some capacity for six or more years.The added financial strain is one concern. Schall says out of pocket expenses can be about a thousand dollars a month.More than half of these caregivers say they're spending more than usual per month to care for others as a result of the pandemic. That means they're contributing less to their savings and their retirement.There's also the concern about the mental toll.“With millennial generation caregivers, you may not be thinking about depression, you know, at that age, but the fact is the sheer stress of the role of being a family caregiver increases that risk of depression twice as often,” said Schall.If you are feeling overwhelmed, the caregiver help desk from the Caregiver Action Network can be one place to turn.

AVALON, Calif. (AP) — The nonprofit organization that owns a majority of California’s Santa Catalina Island plans to boost eco-tourism by adding more bison to existing herds, recharging a debate over their environmental impacts. The Los Angeles Times reports the Catalina Island Conservancy says there has not been a bison calf born on the island in seven years and the herd size has dwindled to 100. The conservancy board is working to bring two pregnant bison to the island. A biologist says bison herds stay on isolated patches of grass and adding more animals will not result in more bison sightings by eco-tourists. 628

As President Donald Trump attempted to sow doubt on this week’s presidential election during a Thursday news conference, several Republican lawmakers criticized Trump for his comments.Currently, Joe Biden is projected to be ahead in the Electoral College vote.
