NASA is calling for test subjects in an experiment that could pave the way to sending humans to Mars or beyond. It’s called the bed-rest study, and it is as extreme as it sounds.
If chosen, participants will have to lay on a bed for 70 days, with their feet elevated slightly higher than their heads. This simulates the long-term effects of microgravity on the human body. The researchers will be able to see how bone density, muscle atrophy, and other bodily factors change as people stay off their feet for months at a time, just like they would on an interplanetary mission. But don’t worry, you can go about your normal daily routine, just as long as it is confined to the bed — there’s a special shower, and you can use consumer electronics (Netflix must have enough decent content for 70 days of constant streaming, right?) Some subjects will even get to use in-bed exercise equipment.
Participants get $18,000 for their time.
So what does it take to endure such hard-core rest? Actually, a lot. Subjects need to be in very good physical condition and undergo psychological evaluation. The application states that participants must pass a modified Air Force Class III medical standard. The senior scientist on the study told Forbes, “We want people who have the physical and psychological characteristics of an astronaut,” albeit a bedridden one.
The insights to be gained here can be crucial for the future of spaceflight. Currently, researchers suggest that a 10-month trip to Mars would cause an astronaut to lose 40 percent of his or her muscle mass. “On a long voyage,” Space.com reports, “a healthy 30- to 50-year-old astronaut could end up with the strength of an 80-year-old.” Something that would be a hindrance when it comes to actually landing on the planet.

In addition to ties between Russia and the Trump campaign, Robert Mueller's team is also "examining a broad range of transactions involving Trump’s businesses as well as those of his associates, according to a person familiar with the probe. FBI investigators and others are looking at Russian purchases of apartments in Trump buildings, Trump’s involvement in a controversial SoHo development in New York with Russian associates, the 2013 Miss Universe pageant in Moscow, and Trump’s sale of a Florida mansion to a Russian oligarch in 2008, the person said. The investigation also has absorbed a money-laundering probe begun by federal prosecutors in New York into Trump’s former campaign chairman Paul Manafort."
"The House voted Thursday to reauthorize the Department of Homeland Security. The bipartisan measure passed easily by a vote of 386-41, with nine Republicans and 32 Democrats voting in opposition. If the bill makes it through the Senate, it would be the first-ever reauthorization of the Department of Homeland Security (DHS) since it was created in the wake of the Sept. 11, 2001, terrorist attacks." Among the provisions it contains is a mandate that the Senate confirm the Secret Service director. It also boosts funding for the Urban Area Security Initiative by $195 million per year.
In remarks scheduled to be delivered today at the American Federation of Teachers' summer conference, President Randi Weingarten "likens U.S. Education Secretary Betsy DeVos to a climate-change denier" and "says the Trump administration's school choice plans are secretly intended to starve funding from public schools. She calls taxpayer-funded private school vouchers, tuition tax credits and the like 'only slightly more polite cousins of segregation.'" The pro-voucher Center for Education Reform said teachers should "consider inviting Weingarten’s resignation."
"President Trump has confidence in Attorney General Jeff Sessions, despite his criticism of the Justice Department head's decision to recuse himself from the Russia probe, the White House said Thursday. 'Clearly he has confidence in him or he would not be the attorney general,' spokeswoman Sarah Huckabee Sanders told reporters at an off-camera briefing."
"The American Civil Liberties Union is suing the Trump administration for records on an executive order President Trump reportedly planned to release targeting the rights of lesbian, gay, bisexual and transgender people. In a lawsuit filed in the U.S. District Court for the Southern District of New York on Thursday, ACLU claimed the departments of Health and Human Services, Justice, Labor, and Treasury violated the Freedom of Information Act by failing to release the records it requested on the reported draft order."
