Attorney General Jeff Sessions ordered a review Friday into how the Justice Department and FBI respond to indications of potential violence after the bureau said it failed to act on a tip about the shooter in the Parkland, Florida, school massacre.A person close to Nikolas Cruz, the confessed shooter, contacted the FBI on January 5 to report concerns about him, the FBI said in a statement Friday. But the bureau did not appropriately follow established protocols in following up on the tip."The information was not provided to the Miami Field Office, and no further investigation was conducted at that time," the statement said.The stunning admission -- which prompted Florida Gov. Rick Scott to call on FBI Director Christopher Wray to resign -- is sure to raise further questions about whether the FBI could have prevented the shooting at Marjory Stoneman Douglas High School, which left 17 dead.  915

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, Ga. – While residents along the Gulf Coast seek shelter from Hurricane Laura, they should still keep the threat of COVID-19 in mind.Emergency managers, shelter managers, and public health professionals are taking measures to reduce the possible spread of the coronavirus among people who seek safety in a disaster shelter during severe weather events like this.For those staying in a shelter during the storm, the Centers for Disease Control and Prevention (CDC) offered some tips to lower the risk of coronavirus infection:Preparing to shelterIf you need to evacuate, the CDC says to prepare a “go kit” with personal items you cannot do without during an emergency. That includes items that can help protect you and others from COVID-19, like hand sanitizer with at least 60% alcohol, soap, disinfectant wipes, and two masks for each person.Know a safe place to shelter and have several ways to receive weather alerts, such as the National Weather Service’s cell phone alerts, NOAA Weather Radio, or NWS alerts on Twitter.Find out if your local public shelter is open, in case you need to evacuate your home and go there. Your shelter location may be different this year due to the COVID-19 pandemic.Follow guidance from your local public health or emergency management officials on when and where to shelter.Make a plan and prepare a disaster kit for your pets. Find out if your disaster shelter will accept pets. Typically, when shelters accommodate pets, the pets are housed in a separate area from people.Follow safety precautions when using transportation to evacuate. If you have to travel away from your community to evacuate, follow safety precautions for travelers to protect yourself and others from COVID-19.While in a public shelterPractice social distancing. Stay at least 6 feet from other people outside of your household.Follow CDC COVID-19 preventive actions—wash your hands often, cover coughs and sneezes, and follow shelter policies for wearing masks. Avoid sharing food and drink with anyone if possible.Follow disaster shelter policies and procedures designed to protect everyone in the shelter, especially those who are at higher risk for severe illness from COVID-19, including older adults and people of any age who have serious underlying medical conditions.Avoid touching high-touch surfaces, such as handrails, as much as possible. Wash hands with soap and water for at least 20 seconds or use hand sanitizers with at least 60% alcohol immediately after you touch these surfaces.Keep your living area in the shelter clean and disinfect frequently touched items such as toys, cellphones, and other electronics.If you feel sick when you arrive at the shelter or start to feel sick while sheltering, tell shelter staff immediately.Keeping children safe in sheltersTeach and reinforce everyday preventive actions for keeping children healthy.Make sure children aged 2 and older wear masks. Masks should not be used by children under the age of 2. They also should not be used by people having trouble breathing, or who are unconscious, incapacitated, or unable to remove the mask without assistance.Be a good role model—if you wash your hands often, your children are more likely to do the same.Help your children stay at least 6 feet away from anyone who is not in your household.Watch your child for any signs of illness and tell shelter staff if your child may be ill.Try to deal with the disaster calmly and confidently, as this can provide the best support for your children. Help children cope with emergencies. 3559

As many public health experts have expressed concern over President Donald Trump's re-election rallies amid the coronavirus pandemic, a study conducted by Stanford University examined the number of illnesses stemming from the rallies.According to the study published last week, the rallies likely caused 30,000 other coronavirus-related infections, resulting in 700 deaths. The study's authors noted that these cases were not specifically from rally attendees, which means that attendees could have spread the virus to others.The study did not use contact tracing; instead, they relied on a statistical model that analyzes the virus's spread in communities Trump held rallies.Specifically, researchers examined 18 rallies Trump held from June 20 to Sept. 22, noting that coronavirus cases in the area near the rallies increased by more than 250 per 100,000 residents."Our analysis strongly supports the warnings and recommendations of public health officials concerning the risk of COVID-19 transmission at large group gatherings, particularly when the degree of compliance with guidelines concerning the use of masks and social distancing is low," the study's authors said. "The communities in which Trump rallies took place paid a high price in terms of disease and death."Trump's rallies have generally included thousands of supporters standing shoulder to shoulder. While masks are often handed to supporters, most supporters at rallies opt not to wear them.Public health experts say that a combination of masks and keeping six feet of distance helps minimize the virus's spread, which has claimed more than 230,000 American lives since the spring.Public health experts have also encouraged people to hold gatherings outside, as most Trump rallies since he resumed campaigning in June have been held outdoors with a few exceptions.Trump has often mocked his opponent Joe Biden, who has held much smaller events to spread out the crowd. Biden has held several "drive-in" style events.Dr. Anthony Fauci, whose recent disagreements with Trump have boiled over on the campaign trail, said in an interview with CNN, he was troubled by Trump's rallies."We know that is asking for trouble when you do that," Fauci told. "We've seen that when you have situations of congregate settings where there are a lot of people without masks, the data speak for themselves."To read the full study, click here. 2403
