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

As the investigation continues into why a female shooter opened fire at YouTube headquarters, data show that it's rare for women to carry out such shootings -- making Tuesday's incident unusual.The shooting unfolded at the San Bruno, California, company premises when a woman shot and injured three people, and then apparently took her own life, officials said.She appeared to have killed herself with a handgun, San Bruno Police Chief Ed Barberini said.

As tensions between law enforcement and the public rise, more cops are saying they need help mentally.For decades, mental health in law enforcement has been stigmatized, says Lieutenant Alexis Zellinger with the Atlantic City Police Department in New Jersey, and she says it has led to suicide being the leading cause of death among officers for the last few years.According to the group Blue H.E.L.P., which has tracked officer suicide since 2015, 2019 was the deadliest year for police in the United States as 228 took their own lives. The organization also reported 172 officer deaths due to suicide in 2018, 168 in 2017, and 143 in 2016.Lt. Zellinger says traumatic incidents on the job can occur several times in one day and are not always related to use of force situations.“I was on a call where we had to perform CPR on an infant,” said Lt. Zellinger. “Going through something like that as a police officer and a woman who has gone through a miscarriage not too far along from that moment; it is something that can be traumatizing."“The climate of the country right now, it’s not great for law enforcement,” added Deputy Chief Bridget Pierce with ACPD.In 2018, New Jersey Attorney General Gurbir Grewal instituted the Officer Resiliency Program as a way to help offer supports to law enforcement personnel who may need it. The program places at least one officer trained to understand and deal with mental health issues inside each department in the state. Grewal says the program traces back to an encounter he had in 2018 with Pablo Santiago, a deputy with the Mercer County Sheriff’s Department in the state.Only a few weeks after the two met and Santiago invited him to a homeless feeding, Grewal says Santiago shot and killed himself in the parking lot outside of his office on the day after Christmas.“He was the picture of community service,” said Grewal. “[He was] vibrant. You never knew anything was affecting him. There is an argument to be made that it’s a line of duty death because it is the trauma and stress of the job.”In Atlantic City, Deputy Chief Pierce and Lt. Zellinger volunteered to become the department’s first two resiliency officers. They started counseling officers within the department only two weeks ago.“In my career [at ACPD]- I’ve been here 24 years- there have been 6 officers who have committed suicide,” said Pierce. “When one of your own takes his own life, you feel partially responsible that you should have seen it coming. One of the officers that we lost years ago was one of my very good friends, who I worked side by side with, rode in the car with, and for a long time that haunted me.”Since the death of George Floyd, Attorney General Grewal says calls to resiliency officers and state hotlines have increased by thousands.“It’s tough. It’s only getting tougher,” said Deputy Chief Pierce.Blue H.E.L.P. says 125 officers have taken their own lives in 2020. 2919
