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

As the school year comes to a close, students will find many ways to thank their teachers.One student in Lackawanna County, Pennsylvania may have found the best way, by helping his teacher win a new car.Students at the Career Technology Center of Lackawanna County were more than happy to head outside to the parking lot on a beautiful day. The short field trip was about to become a lot sweeter for one of the CTC's teachers, who was awarded the title of Burne Honda's Teacher of the Year.Kyle Linko, a welding technology teacher at the school in Scranton, took the title and the grand prize: a brand new Honda Civic. 631

As the death toll from the Camp Fire rose to 63 people, rescue workers searching for human remains in the wreckage hope that hundreds of people who are still unaccounted for after the blaze are still alive.After going through a week of 911 calls, authorities announced Thursday they are looking into reports of 631 people who are possibly missing."You have to understand, this is a dynamic list," Butte County Sheriff and Coroner Kory Honea said Thursday evening. "Some days might be less people, some days might be more people, but my hope at the end of the day, we have accounted for everybody. "Photos: Wildfires devastation in CaliforniaA week after two major wildfires sparked at both ends of the Golden State, the total death toll has increased to 66, fire officials said.The Camp Fire -- now the deadliest and most destructive wildfire in the state -- has left 63 people dead, destroyed about 9,700 homes and scorched 141,000 acres. By Thursday night, it was 40% contained.Hundreds of deputies, National Guard troops and coroners are sifting through leveled homes and mangled cars for human remains."They are going to be searching vehicles that have been burned. They'll be searching residences that have been burned. Checking around the residences ... our mission is to find the victims from this fire, recover them and get them identified and notify the families to give them some answers," Butte County Sheriff's Investigations Sgt. Steve Collins said.President Donald Trump is expected to visit the region Saturday as firefighters continue battling the blaze. 1578

As students begin to head back to the classroom – either virtually or in person – this month begins the most uncertain school year in recent memory.While some public health experts have expressed apprehension about reopening schools, President Donald Trump gave a full-throated defense for bringing back students into classroom full time this fall. Trump hosted a group of educators and school administrators at the White House on Wednesday.Amid Trump’s effort to reopen schools, the CDC released updated guidance last month that emphasizes reopening schools. The new guidance contradicts previous guidance, which recommended closing schools during periods of substantial community transmission.The updated guidance said that extended school closures are harmful to children and can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.During an event with educators on Wednesday, Trump said not only should students return to the classroom, but he decried hybrid schedules, which incorporates a blend of in-person and virtual learning. Proponents of hybrid schedules say that they allow for students to have some in-person learning while opening more classroom space for social distancing.But the president is not a fan.“The concept of every other day seems a little ridiculous, right?” Trump said. “If you are going to do it, you do it. If you are not going to do it, the concept of going back even from a management standpoint from the school, every other day seems very strange.”Trump once again called on Congress to pass 5 billion in education funding, which House Democrats have also pushed for as part of a broader stimulus plan. While Treasury Secretary Steven Mnuchin said the White House is open to doing a piecemeal approach to a stimulus package, House Democrats have pushed for an all-encompassing bill.Some of the funding for schools could be used to help districts with additional costs associated with mitigating the risk of the virus.Trump said that the funds should follow the students. He has previously said that if schools opt for online learning, they should not receive federal funds.“If the school is closed, you know, why are we paying if a school is closed?” Trump asked. “Why are we paying the school if it is closed? I would rather give it to the student, the parents, and you do your own thing, and to me it makes a lot of sense.”While Trump is eager for a full return to school, there are several cautionary anecdotes from several districts that opened earlier this month.Most notably, the Cherokee School District in Georgia reported on Tuesday 59 students and employees tested positive for the coronavirus following its reopening. The district is now asking 925 employees and students to quarantine for two weeks. The district’s Etowah High School will remain closed until August 31 due to the outbreak. 2935
