Lakes on Saturn's moon Titan can stratify like those on Earth https://ift.tt/3jgxho6

Lakes on Saturn's moon - Titan - composed of methane, ethane, and nitrogen rather than water, experience density-driven stratification, forming layers similar to lakes on Earth. However, whereas lakes on Earth stratify in response to temperature, Titan's lakes stratify solely due to the strange chemical interactions between its surface liquids and atmosphere, says a paper by Planetary Science Institute Research Scientist Jordan Steckloff. Stratification occurs when different parts of a lake have different densities, with the less dense layer floating atop the denser layer.

As the city gradually reopens, mechanical street sweeping enforcement is set to resume

As the city gradually reopens, mechanical street sweeping enforcement is set to resume By Mayor London N. Breed and the San Francisco Municipal Transportation Agency (SFMTA) today announced that the City will resume enforcement for parking violations related to street sweeping beginning on Monday, June 15. Mayor Breed had announced on March 17 that SFMTA would not ticket for street sweeping following the Stay Home Order for COVID-19 in order to allow people to stay home without worrying about receiving a parking ticket. While the City had still encouraged people to move their vehicles if they could, street sweeping crews from San Francisco Public Works continue to see a large number of vehicles failing to do so, as many as 18,000 per day. Resuming enforcement for mechanical street sweeping is necessary to ensure that streets remain clean as the City begins to allow more businesses and activities to resume. “At the beginning of the Stay Home Order we wanted to ensure that people wh...

New top story from Time: Sunisa Lee’s Incredible Journey to a Historic Olympic Gymnastics All-Around Gold Medal

https://ift.tt/3zRsjGq The women’s gymnastics all-around final at the Tokyo Olympics was the coronation everyone expected it to be. Only the star was different. After Simone Biles withdrew from the competition to prioritize her mental well-being, American Sunisa Lee stepped into the gaping void left by her iconic teammate and stepped up to win her first gold medal and Team USA’s fifth straight in the event. With a steely calm, the 18-year-old Minnesotan leaned on her consistent execution and a spectacular uneven bars routine—the hardest of any gymnast competing—to triumph in a competition that until days before had seemed a foregone conclusion. [time-brightcove not-tgx=”true”] The absence of the defending gold medalist opened the door for the rest of the field, including Americans Lee and Jade Carey, who replaced Biles . “We were all coming in to compete for second place,” said Lee. “I just had to switch gears. I feel like the whole season I was second to her, so when th...

New top story from Time: Immigration, Guns and the Filibuster: Joe Biden Confronts Challenges in First Press Conference

https://ift.tt/2PrZX3B Joe Biden held his first formal news conference as president 65 days into this presidency, after making a series of consequential moves in the early weeks of his Administration to help curb the COVID-19 pandemic and ease the economic pain in the country. But he didn’t get asked any questions about the coronavirus. Instead, reporters pressed Biden on things his Administration hasn’t done— like taking a position against the Senate filibuster rule, implementing executive action on gun control in the wake of two mass shootings, and stopping the flow of unaccompanied children coming to the U.S. southern border. The focus on Biden’s problems rather than his victories was a reminder that, in the highest office in the land, reality intrudes on even the best laid plans. The Biden Administration has so far been a model of coordinated message discipline. But once Biden formally faced reporters, he was forced to answer questions with responses that stretched ...

New top story from Time: TikTok Gets Reprieve in U.S. as Judge Temporarily Blocks Trump’s App Store Ban

https://ift.tt/3ifHL60 President Donald Trump’s ban on TikTok was temporarily blocked by a federal judge, dealing a blow to the government in its showdown with the popular Chinese-owned app it says threatens national security. U.S. District Judge Carl Nichols granted a preliminary injunction against the ban on the widely used video-sharing network after an unusual Sunday morning hearing. The judge refused to grant an injunction against a November deadline for a sale. TikTok’s owner, ByteDance Ltd., had requested the hold after the president ordered TikTok out of American app stores unless the company sold a stake in its U.S. operations to a domestic buyer. The ban, scheduled to go into effect at 11:59 p.m. in New York, would have removed TikTok from the app stores run by Apple and Google’s Android, the most widely used marketplaces for downloadable apps. People who don’t yet have the app wouldn’t be able to get it, and those who already have it wouldn’t have access to upd...

New top story from Time: Google’s Employee Vaccine Mandate Could Influence Other Companies to Do the Same

https://ift.tt/3BQnXRv (SAN RAMON, Calif.) — Google is postponing a return to the office for most workers until mid-October and rolling out a policy that will eventually require everyone to be vaccinated once its sprawling campuses are fully reopened in an attempt to fight the spreading Delta variant. In a Wednesday email sent to Google’s more than 130,000 employees, CEO Sundar Pichai said the company is now aiming to have most of its workforce back to its offices beginning Oct. 18 instead of its previous target date of Sept. 1. The decision also affects tens of thousands of contractors who Google intends to continue to pay while access to its campuses remains limited. [time-brightcove not-tgx=”true”] “This extension will allow us time to ramp back into work while providing flexibility for those who need it,” Pichai wrote. And Pichai disclosed that once offices are fully reopened, everyone working there will have be vaccinated. The requirement will be first imposed at Goog...

New top story from Time: ‘I Am Not The President’s Lawyer.’ Merrick Garland Vows Independence As Attorney General

https://ift.tt/3siaXOX U.S. Attorney General nominee Merrick Garland assured Congress on Monday that he would remain independent of partisan influences if he is confirmed to the post. Garland, one of President Joe Biden’s highest-profile nominees, would oversee a wide-reaching department that has a hand in everything from the prosecution of rioters who stormed the Capitol on Jan. 6 to the nation’s broken immigration system. He’s set to take over the Department at a particularly fraught moment, with a crisis in confidence about the DOJ’s impartiality spurred by Donald Trump’s presidency and numerous hot-button political investigations underway, including one into the financial dealings of Biden’s son Hunter and another into the origins of the Trump-Russia probe. How Garland navigates the tricky partisan environment could have huge consequences for public faith in the Department. On his first day of hearings before the Senate Judiciary Committee, Garland navigated question...

New top story from Time: U.S. Executes Brandon Bernard Despite High-Profile Appeals for Clemency

https://ift.tt/3m9uspm (TERRE HAUTE, Ind.) — The Trump administration on Thursday carried out its ninth federal execution of the year and the first during a presidential lame-duck period in 130 years, putting to death a Texas street-gang member for his role in the slayings of a religious couple from Iowa more than two decades ago. Four more federal executions, including one Friday, are planned in the weeks before President-elect Joe Biden’s inauguration. The case of Brandon Bernard, who received a lethal injection of phenobarbital inside a death chamber at a U.S. prison in Terre Haute, Indiana, was a rare execution of a person who was in his teens when his crime was committed. Several high-profile figures, including reality TV star Kim Kardashian West, had appealed to President Donald Trump to commute Bernard’s sentence to life in prison. With witnesses looking on from behind a glass barrier, the 40-year-old Bernard was pronounced dead at 9:27 p.m. Eastern time. Bernar...
