[h=2]Scott Kelly is home after a #YearInSpace. Let the weird science begin.[/h]NASA astronaut Scott Kelly<span style="color: Red;">*</span>is back on Mother Earth<span style="color: Red;">*</span>after<span style="color: Red;">*</span>340 consecutive days<span style="color: Red;">*</span>in space,<span style="color: Red;">*</span>more than any American in history. Welcome home, Scott! His mission centered on determining<span style="color: Red;">*</span>how long-term spaceflight affects the human body. Big picture, we want to figure out how to send a crewed mission<span style="color: Red;">*</span>to Mars. To do that, we have to figure out how to keep astronauts in space a helluva long time without gravity.<span style="color: Red;">*</span>NASA will perform tests to see how Kelly's body has changed. Those changes will be compared to his identical twin, retired astronaut Mark Kelly, who remained on the ground and is also undergoing tests.<span style="color: Red;">*</span>What’s Scott going to do now that he’s back on Earth? "I’m going to go home and jump in my pool,” he said. Gravity baby steps.
[h=2]Leo has an Oscar and the ability to see into our blazin' hot future<span style="color: Red;">*</span>[/h]Remember when Leonardo DiCaprio said in his Oscar acceptance speech Sunday that climate change was no joke? We just broke another worldwide temperature record. The Earth's temp soared to a record high in February, a whopping 1.5 degrees above average. That's a huge amount in climate science, where records are often broken by hundredths or tenths of degrees. Who's to blame? Us. As usual. Also, El Niño.
[h=2]Could the eight-member Supreme Court split on major abortion case?[/h]The Supreme Court heard 85<span style="color: Red;">*</span>minutes of debate Wednesday on the biggest case affecting reproductive rights since 1992.<span style="color: Red;">*</span>Abortion clinics<span style="color: Red;">*</span>in Texas are challenging a state law that imposes tough restrictions<span style="color: Red;">*</span>on the facilities. Complicating the case is the recent death of conservative Justice Antonin Scalia, leaving the court without a ninth member.<span style="color: Red;">*</span>If Justice Anthony Kennedy, who likely holds the deciding vote, sides with the court's liberal wing to strike<span style="color: Red;">*</span>down any part of the law, the ruling could affect<span style="color: Red;">*</span>similar abortion restrictions<span style="color: Red;">*</span>in other states. Or Kennedy and the other justices could return the case to Texas for additional fact-finding. Another possible<span style="color: Red;">*</span>outcome:<span style="color: Red;">*</span>A<span style="color: Red;">*</span>4-4 vote, likely decided by the end of June, would uphold a lower-court ruling that lets the Texas<span style="color: Red;">*</span>law<span style="color: Red;">*</span>stand and would apply only to Texas.
