The Associated Press is reporting that six officers involved in the arrest of Freddy Gray — a young black man who died in the custody of Baltimore Police in 2015 — will not face federal charges.The U.S. Department of Justice announced Tuesday that the officers would not face charges from the federal government. Six officers were charged at the state level, three of which were acquitted. Three others had their cases dropped.Gray died on April 19, 2015, a week after he suffered a spinal injury while in custody after he was arrested for carrying a switchblade a week earlier.  597

The Arctic is experiencing a multi-year stretch of unparalleled warmth "that is unlike any period on record," according to the 2018 Arctic Report Card, a peer-reviewed report released Tuesday morning from the National Oceanic and Atmospheric Administration, an agency within the United States Department of Commerce.The report states that human-caused climate change is transforming the Arctic, both physically through the reduction of sea ice, and biologically through reductions in wildlife populations and introduction of marine toxins and algae.The report is yet another study from part of the US government indicating that climate change is real and having a profound impact, despite denials from the President and senior members of his Administration.Temperatures in the Arctic are warming more than twice as fast as the overall planet's average temperature, with temperatures this year in the highest latitudes (above 60 degrees north) coming in 1.7 degrees Celsius (3.1 degrees Fahrenheit) above the 1981-2010 average. These were the second warmest (behind 2016) air temperatures ever recorded during the Arctic year, which runs from October through September to avoid splitting the winter season.The five years since 2014 have been warmer than any other years in the historical record, which goes back to 1900. Although Arctic temperatures have been subject to wild swings back and forth through the decades due to natural variability, they have been consistently warmer than average since 2000 and at or near record since 2014, the report states."The changes we are witnessing in the Arctic are sufficiently rapid that they cannot be explained without considering our impacts on the chemistry of the atmosphere," Thomas Mote, a research scientist at the University of Georgia who authored part of the report, told CNN in an email.Mote expressed than any natural cycle or mechanism that would lead to the amount of warming and ice loss that has been observed would take much longer than the few years over which we have seen these drastic changes. 2074

'The Big Bang Theory' will go out with a bang in 2019.Warner Bros. Television, which produces the series, and CBS have announced that the comedy's upcoming Season 12 will be its last.The show will conclude as the longest-running multi-camera sitcom in TV history, the studio said.In a joint statement, Warner Bros. Television, CBS and Chuck Lorre Productions said: "We are forever grateful to our fans for their support of 'The Big Bang Theory' during the past twelve seasons. We, along with the cast, writers and crew, are extremely appreciative of the show's success and aim to deliver a final season, and series finale, that will bring 'The Big Bang Theory' to an epic creative close.""The Big Bang Theory" debuted in 2007 and has since notched 52 Emmy nominations and 10 wins, including four individual honors for Jim Parsons in the lead actor in a comedy category and one for Mayim Bialik for best supporting actress in a comedy series.The show, which began as a story about a group of sci-fi-loving intellectuals who form a pseudo-family, saw some dips in its ratings last year but largely remained a stalwart for CBS.The decision to bring the show to an end likely came despite efforts from the network to secure another season.Earlier this month, CBS Entertainment president Kelly Kahl said the network did not believe Season 12 would be it's last, saying they were "in preliminary discussions to renew the show."The series stars Parsons, Johnny Galecki, Simon Helberg, Kunal Nayyar, and Kaley Cuoco, as well as Bialik and Melissa Rauch, who joined the fold in later seasons.At its conclusion, the show will have aired 279 episodes.The final season debuts September 24. 1685

Terminally ill British toddler Alfie Evans died overnight, days after life support was withdrawn, according to messages posted by his parents on Facebook on Saturday."My gladiator lay down his shield and gained his wings at 02:30. absolutely heartbroken. I LOVE YOU MY GUY," his father, Thomas Evans, wrote on the "Save Alfie Evans" Facebook page."Our baby boy grew his wings tonight at 2:30 am. We are heart broken. Thankyou everyone for all your support," his mother, Kate James, posted on the "Alfies Army Official" Facebook page.The 23-month-old boy, who had a degenerative brain condition, had been at the center of a high profile legal battle over whether life support should be continued. The case has stirred strong emotions both in Britain and abroad, with hundreds of thousands signing petitions supporting him.Alfie, who was admitted to Alder Hey Hospital in December 2016, was diagnosed with a neurodegenerative disease associated with severe epilepsy and had been in a semivegetative state for more than a year. During that time, he was kept alive by artificial ventilation in the critical care unit. 1121

TAMPA, Fla. — Air conditioning units may be contributing to the spread of COVID-19, especially in the southern part of the United States, according to a Harvard epidemiologist.Dr. Edward Nardell is a professor in the Departments of Environmental Health and Immunology and Infectious Diseases at the Harvard T.H. Chan School of Public Health. He's done in-depth research on how air conditioning units contribute to the spread of airborne infections.Nardell said air conditioning can help airborne viruses spread in three ways.First, people go inside to cool down, when you are much safer outdoors, Nardell said. Now, we're seeing more people indoors because of the high heat and humidity, specifically in the southern states like Florida.The second problem is that air conditioning brings in very little outside air, according to Nardell. While this isn't a major problem inside your own home, it can be especially problematic in corporate settings."It just isn't economically possible to bring in outside air, recirculate it and dehumidify it," he said.Lastly, he said when people are indoors, you're often not spaced out safely as you would be outdoors."You are not socially distanced as much, but you're re-breathing the same air that someone else just exhaled," Nardell said. "We call it rebreathed air fraction, and if someone is infectious, often asymptomatic, you're going to be rebreathing their small particles."Nardell also said air conditioning units can generate air currents that can carry large particles even further, similar to what researchers found contributed to the spread of the novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China, involving three family clusters.On the Department of Homeland Security's website, this tool can be used to estimate how long the virus would be expected to remain stable while airborne.Now, the Centers for Disease Control and Prevention is recommending restaurants increasing the distance between tables and improving ventilation.The use of germicidal lamps, a technology that Nardell said is almost 100 years old, has been proven effective in protecting against tuberculosis infection and is already in use in some settings to fight COVID-19.The lamps are set up to shine horizontally, high in the room where sterilization is needed. Air currents, stirred in part by warmth from human bodies, circulate up to the ceiling, where the ultraviolet light kills floating pathogens, and then back down again.This technology, Nardell said, is not only proven, but it can also be deployed cheaply and easily in a number of settings as society reopens.This story was originally published by Lauren Rozyla at WFTS. 2691
