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 two sheriff's offices in Florida are investigating after voters in the state say they received threatening messages from people claiming to be affiliated with the Proud Boys that attempt to scare voters into voting for President Donald Trump.According to Florida Today, the emails sent to voters followed a similar format: The sender claimed to be in possession of personal information because they "gained access" to the "entire voting infrastructure." The message then says the voter must "vote for Trump on Election Day or we will come after you."Florida Today reports that the Brevard Supervisor of Elections has reported the messages to local law enforcement. In a Facebook post, the sheriff of Alachua County, located several hours northwest of Brevard County, said it was investigating similar messages with assistance from federal law enforcement. 872

Babies have such a bad reputation when it comes to staying quiet on plane rides that some parents go so far as to hand out treats to fellow passengers before the plane has even taken off. Indeed, George and Amal Clooney, world travelers and parents of twin babies, made headlines late last year for gifting headphones to some passengers, along with a note apologizing in advance for any crying.While there’s no need to pack dozens of gifts in your diaper bag, travel and parenting experts recommend other strategies to increase your chances of a smooth flight with your baby. 603

ASHLAND, Ore. (AP) — The northbound lanes of Interstate 5 have reopened heading from Redding, California all the way to the Oregon border. California transportation officials said Wednesday the freeway was clear and no chains are required.I-5 was closed in both directions near the California-Oregon border Tuesday, stranding hundreds of people.Drivers reported being stuck for hours in white-out conditions and some even spent the night in their cars.The storm -- called a “bomb cyclone” -- came ashore near Brookings, Oregon late Tuesday afternoon packing heavy snow and winds gusting up to 106 mph (170 kmh).The southbound lanes reopened at Ashland, Oregon early Wednesday.Don Anderson, deputy director of the California Department of Transportation in Redding, says Caltrans and many other agencies worked hard to communicate the seriousness of the storm but that many drivers were still caught by surprise. 919

ATLANTA (AP) — Georgia’s governor, Brian Kemp, is explicitly banning the state's cities and counties from ordering people to wear masks in public places.He’s voiding orders that at least 15 local governments across the state had adopted even though Kemp had earlier said cities and counties had no power to order masks.The Republican governor has instead been trying to encourage voluntary mask wearing.An increasing number of other states have ordered residents to wear masks in public, including Alabama, which announced such a ban Wednesday.Kemp’s move is likely to infuriate local officials in communities that had acted, including Atlanta, Augusta, Savannah, Rome and the governor’s hometown of Athens-Clarke County. 729
