Astronomers looking at the atmosphere in neighboring Venus see something that might just be a sign of life.In a study published Monday, researchers from Cardiff University, MIT and elsewhere say they found the chemical signature of a noxious gas called phosphine.On Earth, phosphine is associated with life. It's found at the bottom of ponds, in badger guts and in penguin guano.Venus’ phosphine was observed in a narrow, temperate band within the planet’s atmospheres, where temperatures range from 30 to 200 degrees Fahrenheit. Scientists have speculated that if life exists on Venus, this layer of the atmosphere, or cloud deck, is likely the only place where it would survive, according to MIT.“This phosphine signal is perfectly positioned where others have conjectured the area could be habitable,” said the study’s co-author and EAPS Research Scientist Janusz Petkowski.Astronomers tried to figure out other, non-biological ways it could be produced and came up empty.“It’s very hard to prove a negative,” said Clara Sousa-Silva, research scientist in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “Now, astronomers will think of all the ways to justify phosphine without life, and I welcome that. Please do, because we are at the end of our possibilities to show abiotic processes that can make phosphine.”Outside experts — and the study authors themselves — say the research is tantalizing but not yet convincing. 1454

At least 257 people have been killed in a military plane crash near Algeria's capital, Algiers, state media reports.The aircraft crashed near the Boufarik air base, between Algiers and the city of Bilda. Ten of those killed were the plane crew, according to state-run Radio Algerie.It was not immediately clear whether there were any survivors.TV station Ennahar showed images of smoke rising from the plane's fuselage, tilted to one side, with part of the aircraft sticking out above olive trees.

At least one airline is starting to pull back on their cleaning regimen. Southwest crews are limiting their between-flight cleanings and leaving most of the passenger areas for the overnight cleaning crew, according to reports.Following the coronavirus outbreak in March and subsequent travel bans, airlines touted their stepped-up cleaning protocols as passengers returned.Starting in August, Southwest is focusing on lavatories and tray tables between flights, leaving seat belts, arm rests and other areas for the overnight cleaning crew, Southwest representative Ro Hawthorne told the Dallas Morning News."Since flight schedules have increased, other areas of the aircraft will be disinfected during our overnight cleaning process, when Southwest Teams spend six to seven hours per aircraft cleaning all interior surfaces," Hawthorne said in a statement.“As always, Southwest will monitor customer and employee feedback as we adapt to the new normal in air travel, while ensuring we keep safety as our top priority,” the statement continued.In March, Southwest announced their cleaning program included "interior windows and shades, every seat belt buckle, passenger service units (including the touch buttons that control reading lights and vents that direct personal air), as well as seat surfaces, tray tables, armrests, etc."The change to cleaning protocol will reduce the time an aircraft spends on the ground between flights, the airline told flight attendants in a memo obtained by CNN. 1505

At least 18 people have been killed and 178 others injured after a train derailed in Yilan County in northeastern Taiwan, according to an update from the island's transport ministry.Initially, the ministry said 22 people died, but it later revised the number.The train was traveling between the cities of Shulin and Taitung when it derailed Sunday on a coastal line reportedly popular with tourists.The train was carrying 366 passengers when the accident occurred just before 5 pm local time, the transport ministry said. 529

As White House advisers and congressional leaders spar over the next round of stimulus funds, President Donald Trump said on Tuesday that he still has some issues with the Senate GOP's proposal released yesterday.On the mind of so many Americans are stimulus checks, unemployment and the return to school.But when asked specifically what he disagreed with, Trump punted. Despite a Trump administration push for the return of in-person learning, a number of school districts across the US have announced plans to begin the 2020-21 school year virtually. On Tuesday, Ohio’s largest district Columbus City Schools said they will start the year off virtually.Trump has said that federal funds should only go to schools that are open.Meanwhile, the next round of stimulus is being debated on Capitol Hill. While it appears there is agreement between the White House, House Democrats and Senate Republicans on providing a second round of ,200 checks for most Americans, there is intense debate on unemployment. Last week, millions of unemployed Americans stopped receiving a 0 weekly supplement to unemployment checks. Those checks were in addition to state unemployment payments.With those payments no longer being received by Americans, there are questions on the state of the economy given an unemployment rate of 11.1 percent – nearly three times higher than at the start of the year.HIGHLIGHTS OF THE ACT:- ,200 stimulus checks for the same group of Americans who received a check in the spring- 6 billion in funds for schools to hire staff and conduct social distancing- Replenishing the Paycheck Protection Program, intended to help businesses keep employees on payroll- Extending unemployment supplement, although at a lower amount- Liability protection for businesses reopening amid the pandemic 1816
