Since it landed on Mars in 2012 NASA's Curiosity rover has been exploring Gale Crater, a vast, dry ancient lake bed with a mountain at its center. Now, Curiosity has found sediments containing sulfate salt in the crater, which suggest it once held salty lakes.A range of salts have been found on Mars in different locations. Researchers interpret these as evidence of ancient brines. Salty water formations seemed to increase on the Martian surface as the planet transitioned to an arid climate 3.5 billion years ago.The new detection of sulfate salts came from sedimentary rocks dated to between 3.3 and 3.7 billion years ago. Curiosity has analyzed other, older rocks on Mars and didn't detect these salts in them.Researchers believe the salt is evidence of the crater's lake evaporating in the Red Planet's arid environment. They also believe studying younger rocks in the future could shed more light on how the Martian surface dried out.Gale Crater was created by an ancient impact, then filled in with sediment layers over time. Mount Sharp, the mountain at its center, was created by wind erosion of the hardened sediment layers. Those same layers act like chapters in the history of Mars and provide clues to its environment at each point in time.At the time the sulfate salts were present, lakes were probably scattered across the crater floor, fed by streams in the crater walls. Over time, the streams would overflow and then evaporate, trapped in a repetitive cycle taking place over millions of years.The findings were published Monday in the journal 1576

Quincy Mason, George Floyd's son, visited a memorial for his father on Wednesday at the site where his father was arrested prior to his death in Minneapolis police custody."We want justice for what's going on right now," Mason said. "I appreciate everyone showing support and love, and I thank you."Mason was accompanied by Ben Crump, the lead attorney for the family of George Floyd. Crump said Wednesday that he expects three of the officers involved in Floyd's arrest to be charged in connection with his death before a 535

Screen time use by infants, toddlers and preschoolers has exploded over the last decade, concerning experts about the impact of television, tablets and smartphones on these critical years of rapid brain development.A new study scanned the brains of children 3 to 5 years old and found those who used screens more than the recommended one hour a day without parental involvement had lower levels of development in the brain's white matter -- an area key to the development of language, literacy and cognitive skills."This is the first study to document associations between higher screen use and lower measures of brain structure and skills in preschool-aged kids," said lead author Dr. John Hutton, a pediatrician and clinical researcher at Cincinnati Children's Hospital. The study was 799

Some consumers hoping to get compensation for a massive 2017 data breach at credit bureau Equifax are running into trouble: The settlement site’s eligibility tool seems glitchy, phone lines are jammed, and fake websites are trying to sucker people into divulging personal data. 289

Stormy Daniels, the adult film star who claims to have had an affair with President Donald Trump in 2006 and whom Michael Cohen paid to keep quiet during the 2016 election, issued a statement Wednesday as lawmakers grilled Cohen on Capitol Hill.Daniels said she was "proud" that Cohen was "beginning to tell the truth" about her alleged affair with the president and subsequent hush money payments.She also took Cohen to task for allegedly threatening her to keep quiet about the affair in the years after receiving payment."You spoke about how the president and his attorney put you and your family in danger by calling you a liar and a rat and disparaging you in public," Daniels said in her statement. "I understand your fear, Michael. I have a family too. Do you believe now that when you and the president called me a liar, when you were his attorney and insulted me, threatened to bankrupt me and worse, that you put me and my family in danger? I remember the fear you feel. I still feel it."On Wednesday, Cohen brought a check to the hearing which he says was repayment from Trump for issuing a hush money payment to Daniels. Cohen also testified on Wednesday that Trump directed Cohen to lie to Trump's wife, Melania, about the affair — an order that he carried out and says he still regrets to this day.Cohen was sentenced to three years in prison in late 2018 for lying to Congress and for campaign finance charges relating to the payments to Stormy Daniels.MSNBC reporter Garrett Haake published Daniels' statement first. Daniels added she will not be issuing another statement today.Read Daniels' entire statement below. 1644
