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.

At 16 years old, Gabe Richards has been working hard to get good grades.He's secured straight As while being a part of the special education program at Marysville High School in Michigan.But, after getting invited to be honored at an academic awards ceremony Monday night, Gabe said he was disappointed to be told at the event that his invite was a mistake."We were really excited and don't get the chance to celebrate achievements all the time," said his mother Stefanie Grassel.Grassel said the faculty did apologize and acknowledge they mistakenly sent an invitation letter.However, as a mother, Grassel said she wants to see the policy changed to become more inclusive."It sends the message that they are less than a general education student, and that's wrong," she added.Richards also told us he feels disappointed after what happened. District superintendent Shawn Whiteman refused to do an interview in response to what happened. Instead, he issued the following statement addressing the matter:"The criteria for students to receive the distinguished “Academic Award” from Marysville High School are a GPA greater than or equal to 3.5 and that they are enrolled in a certain amount of academic-based classes.After speaking with our high school principal, it was evident that a mistake was made when identifying students for this award, due to the fact that a letter was sent home inviting a student to the ceremony who didn’t meet the full criteria.It is clear that the high school made an error in identifying students for this year’s award and we respectfully apologize for any grief this has caused.  Because of this, we will be taking corrective action so that this does not happen again in the future." 1768

As the Miami Marlins and Philadelphia Phillies prepare to return to play following a week hiatus, the St. Louis Cardinals will be forced to sit out for another few days.On Monday, MLB announced it has postponed this week's three-game series between St. Louis and Detroit following a number of Cardinals players testing positive for the coronavirus late last week. The Cardinals' COVID-19 outbreak was the second COVID-19 rash MLB has encountered since resuming the season 11 days ago.According to MLB, 13 members of the Cardinals, including players and staff, have tested positive for the virus. The team has been holed up in Milwaukee since Thursday and remains quarantined there. The team is slated to resume play on Friday in St. Louis against the Cubs.The start of the coronavirus-shortened MLB season has been bumpy as several prominent players have opted to walk away from the season. Most notably, Mets star slugger Yoenis Cespedes said Sunday he would no longer participate in the 2020 season over coronavirus concerns.Earlier in the weekend, Red Sox ace Eduardo Rodriguez declined to return to baseball after facing complications from the coronavirus. Rodriguez told MassLive that he discovered a heart condition following his bout with the virus. 1264

As more people turn to ketamine infusions to treat depression, researchers issue a new warning, comparing the drug to opioids.The infusions are offered at clinics located across the country. Scientists believe ketamine may treat symptoms of depression by blocking receptors on the brain.At Florida’s Ketamine Health Centers, clinical director May Nunez says they've seen an 85 percent success rate.“A lot of our patients come in, and they are highly suicidal. They are very treatment resistant,” explains Nunez. “They're experiencing high levels of depression. They have one infusion administered, and they come out. I'm basically looking at those symptoms are gone.”But new research from Stanford University is raising questions about using the drug over a long period of time.When patients in the study took an opioid blocker, researchers said their symptoms didn't improve, suggesting ketamine has to activate opioid receptors before treating depression.Researchers say that doesn't mean you shouldn't use ketamine, but instead, that more studies need to be done to fully understand ketamine before it's widely used in the long-term.Nunez says the side effects she's seen have been minimal.“So, what I always tell the patients is, you know, you're not going to get worse,” says Nunez. “You're either going to be in remission, sore or you're simply not going to respond.” 1386
