As the Democrats kicked off Night No. 1 of its four-night virtual national convention, George Floyd’s brother Philonise Floyd spoke out against his brother’s death.Philonise Floyd led the convention in a moment of silence in honor of his brother and others who have died as victims of "hate and injustice.""George should be alive today,” Philonise Floyd said. “Breonna Taylor should be alive today. Ahmaud Arbery should be alive today. Eric Garner should be alive today. Stephon Clark, Atatiana Jefferson, Sandra Bland—they should all be alive today. So it's up to us to carry on the fight."While most of those named by Philonise Floyd died while in police custody, Arbery was killed in a shooting by civilians. Three Georgia men, Travis McMichael, Gregory McMichael, and William "Roddie" Bryan were charged in connection with Arbery's death. His death came to light after it took 74 days before anyone was charged in connection with his death. Preceding Floyd at the virtual convention was Muriel Bowser, Washington D.C.’s Democratic mayor who called out President Donald Trump for using federal agents to deploy tear gas on a crowd of Black Lives Matter protests. During the height of the protests, federal agents used tear gas to disperse a crowd moments before Trump emerged from the White House to visit a burned out church across the street from the White House.“Where we were peacefully protesting, Donald Trump was plotting,” she said. “He stood in front of one of our most treasured houses of worship and held a Bible for a photo op. He sent troops in camouflage into our streets. He sent tear gas into the air—federal helicopters, too. I knew if he did this to D.C., he would do it to your city or your town.”During Bowser’s remarks, Trump’s campaign panned Bowser for saying she was “proud” of protesters. While Bowser wouldn’t initially commit to removing a “Defund the Police” mural from a D.C. street, city crews have since paved over the mural. 1967

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

Authorities are racing to rescue three people trapped in a West Virginia mine.Four individuals were reported missing Saturday after an abandoned ATV they were believed to be riding was found near the entrance of a mine in Clear Creek, according to a statement from the office of West Virginia Gov. Jim Justice.One of the four emerged from the mine alive and on his own late Monday night, the West Virginia Office of Miners' Health, Safety and Training said.The man said that the three people left trapped were alive and gave authorities details on their location, according to Justice's office.Rescue teams were unable to locate them overnight Monday. Rescuers expanded their search on Tuesday after removing standing water from the mine and pumping in fresh air, the statement from the governor's office said. 818

At 16 years old, Gabe Richards has been working hard to get good grades.He's secured straight As while being a part of the special education program at Marysville High School in Michigan.But, after getting invited to be honored at an academic awards ceremony Monday night, Gabe said he was disappointed to be told at the event that his invite was a mistake."We were really excited and don't get the chance to celebrate achievements all the time," said his mother Stefanie Grassel.Grassel said the faculty did apologize and acknowledge they mistakenly sent an invitation letter.However, as a mother, Grassel said she wants to see the policy changed to become more inclusive."It sends the message that they are less than a general education student, and that's wrong," she added.Richards also told us he feels disappointed after what happened. District superintendent Shawn Whiteman refused to do an interview in response to what happened. Instead, he issued the following statement addressing the matter:"The criteria for students to receive the distinguished “Academic Award” from Marysville High School are a GPA greater than or equal to 3.5 and that they are enrolled in a certain amount of academic-based classes.After speaking with our high school principal, it was evident that a mistake was made when identifying students for this award, due to the fact that a letter was sent home inviting a student to the ceremony who didn’t meet the full criteria.It is clear that the high school made an error in identifying students for this year’s award and we respectfully apologize for any grief this has caused.  Because of this, we will be taking corrective action so that this does not happen again in the future." 1768

Attorney General Bill Barr has accepted an invitation to appear before the House Judiciary Committee on July 28, according to a statement from Kerri Kupec, the Director of Communications at Justice Department.The House Judiciary Committee has been conducting oversight hearings regarding potential political interference from Trump administration officials in certain cases connected to Special Counsel Robert Mueller's investigation.Several media outlets reported this week that Judiciary Chairman Jerry Nadler, D-New York, had been considering issuing a subpoena to Barr to force his testimony.House Democrats on the Judiciary Committee claim that Barr has intervened on President Donald Trump's behalf in numerous instances since he replaced Jeff Sessions as AG in February 2019.Over the weekend, Barr announced that Geoffrey Berman — who had been investigating Trump's financials in is role as the U.S. Attorney for the Southern District of New York — had resigned. Berman quickly refuted the claim, saying he had learned of his "resignation" in the media. Barr later announced that he had fired Berman, and Berman only agreed to step aside when he was assured that his hand-pick successor could continue investigating unimpeded for the time being. 1260
