Anyone scared of snakes on the ground may not want to read this story — because the reptiles are also in the sky.The paradise snake, which is native to south and southeast Asia, has been known to scientists for some time. But they never really understood how the species — and others like it — are able to glide through the air.Researchers at Virginia Tech conducted controlled tests with the snakes in an indoor environment. They discovered that the undulating motion the snakes exhibit while gliding stabilizes them, which allows them to fly further. Previously, researchers thought the snakes' movements in the air were the same movement they used when slithering on the ground.Now, researchers say they want to learn how the snakes generate lift and how they can turn in the air.Luckily, while the paradise snake is poisonous, its venom is weak compared to other species. Like almost all snakes, the paradise snake is considered harmless to humans. 960

An eruption from the Kilauea volcano's summit shot ash and smoke into the air early Thursday on Hawaii's Big Island, and the resulting plume is expected to cover the surrounding area, according to the Hawaiian Volcano Observatory.Nearby residents are being asked to shelter in place if they are in the path of the ash plume, which the wind is carrying to the southeast of the volcano."Driving conditions may be dangerous so if you are driving pull off the road and wait until visibility improves," an alert from the observatory warned.Thursday's eruption is just the latest volcanic activity contributing to the nightmare on the Big Island since the volcano first went off May 3.An ash plume Wednesday rose roughly 12,000 feet into the air, and on Tuesday, the US Geological Survey issued a red alert, which means a major eruption is imminent or underway and ash could affect air traffic.It is not clear if this was a phreatic eruption, which US Geological Survey officials have been saying is capable of sending ash plumes as far as 12 miles away from the summit.These are steam-driven explosions that occur when water beneath the ground or on the surface is heated by magma, lava, hot rocks or new volcanic deposits, the USGS says. The intense heat may cause that water to boil and result in eruptions.The lava lake in the crater has been dropping since May 2, which increases the chances for a phreatic explosion, but it will be difficult to warn residents who may be in the path of such an eruption.Phreatic eruptions are "notoriously hard to forecast, and can occur with little or no warning," Hawaiian Volcano Observatory geologist Janet Babb said.While the ash being launched into the sky is not poisonous, Hawaii County officials have warned residents about toxic sulfur dioxide seeping out of 21 fissures caused by the volcano."Severe conditions may exist such as choking and inability to breathe," the county's Civil Defense Agency said Wednesday. "This is a serious situation that affects the entire exposed population."The-CNN-Wire 2051

An Atlanta police officer has been fired following the fatal shooting of a black man and a second officer was placed on administrative duty. The move announced by police early Sunday comes on the heels of the resignation of Atlanta's police chief following the killing of 27-year-old Rayshard Brooks. Police identified the fired officer as Garrett Rolfe. Atlanta Mayor Keisha Lance Bottoms said she doesn’t believe the shooting was justified. "It has become abundantly clear that over the last couple weeks in Atlanta is that while we have a police force full of men and women who work alongside our communities with honor respect and dignity," Bottoms said, "there has been a disconnect with what our expectations are, and should be as it relates to interactions with our officers and the communities in which they are entrusted to protect."The Georgia Bureau of Investigation say Brooks resisted arrest after he failed a field sobriety test and a struggle ensued over a Taser. Police say 36 people were arrested at Saturday night protests. A Wendy's restaurant, which was the site of Brooks' death, was destroyed amid the unrest on Saturday.Police have released body camera and dash camera footage.The Georgia Bureau of Investigations said that officers responded to a call of a man who fell asleep behind the wheel in a drive thru. The police accused Brooks of failing a field sobriety test.Police then claimed Brooks struggled with officers during the arrest. The Georgia Bureau of Investigations said that officers then fired a Taser at Brooks.Eyewitnesses told investigators that Brooks then struggled with officers over the Taser, and that’s when Rolfe officer shot Brooks.Brooks was transported to the hospital, and he died during surgery.Atlanta has been the site of a number of large protests in recent weeks in the wake of the death of George Floyd. Floyd died on Memorial Day in police custody after a Minneapolis police officer held a knee against his neck for nearly nine minutes.The NAACP reacted to Saturday's shooting via Twitter."Stop urging the black community to be patient as our people are being gunned down by those sworn to 'protect and serve.' Sweeping police reform is no longer a consideration," the NAACP said in a statement. 2261

ANAHEIM, Calif. (AP) — Walt Disney Co. has put a hold on construction plans for a luxury hotel in the Disneyland Resort's shopping district, citing a feud with Anaheim officials over tax subsidies.The Los Angeles Times reports a letter dated Wednesday from the chief counsel for Disneyland Resorts, David Ontko, to Anaheim City Attorney Robert Fabela says the company has no other choice than to put the construction on hold indefinitely as it "reevaluates the economic viability of future hotel development in Anaheim."The dispute centers on a 7-million tax break Anaheim City Council approved in 2016 for a 700-room hotel.Anaheim Chamber of Commerce President Todd Ament calls Disneyland's decision to halt development of the hotel a "devastating blow to Anaheim and a direct result of the city's increasingly hostile actions towards our local economy." 876

ANCHORAGE, Alaska — A powerful 7.8 earthquake has struck the Alaska Peninsula, triggering a tsunami warning that sent residents fleeing to higher ground before it was called off without any damaging waves. According to the U.S. Geological Survey, the 7.8 magnitude quake struck Tuesday at 10:12 p.m. local time. The quake was centered in waters 65 miles (105 kilometers) south-southeast of Perryville, Alaska at a depth of 17 miles (28 km), deeper than an earlier estimate. The quake triggered tsunami warning for a South Alaska, the Alaska Peninsula and the Aleutian Islands that was called off early Wednesday about two hours after the quake. 652
