N165 is the (un)luckiest bit of basalt on Mars. Which is saying something because there is a lot of basalt on Mars.
Meet the most boring rock in the world. It's probably basalt, an igneous rock, which makes it like many, many other rocks and pebbles all over the world.
What makes it interesting is that the world in question is Mars, and this random little piece of stone happens to be sitting near the Mars Curiosity rover on the floor of the Gale crater.
And, N165, as it is being temporarily called, also happens to have a nice, flat face that happens to be in the range of the rover's laser.
That all makes this poor little guy a perfect test rock for everyone's favorite Martian robot to fire upon. The rover is going to fire 30 laser bursts over 10 seconds, capturing the light generated by the tiny bit of plasma that the laser will create with each blast. Each element (e.g.oxygen) and rock (e.g. basalt) has a distinctive signature that the ChemCam can detect. This spectrographic technique is fast and will be deployed thousands of times on Mars.
What do they expect to find when they blast a tiny hole in N165? Well, not much. "We didn't pick it for its science value per se," said Roger Wiens, the ChemCam principal investigator.
They already think they know, in fact, what they're looking at in this small rock. "If I were to make my guesses, I would probably guess this is a typical Mars basalt," Wiens continued. "Basaltic rocks making up a large percentage of all the igneous rocks on Mars or maybe even all of them... So basalts typically have 48 percent silicon dioxide, and percent amounts of iron, calcium, magnesium, potassium oxides, as well. We're not really expecting any surprises."
Yup, this really is just another rock. On Mars.
(Coda: perhaps the most disappointing thing about travel to outer space is that all the same rules apply. Like, it turns out that the laws of the universe are the laws of the universe. And deep down, don't we all just wish that we would go to Mars and suddenly *everything* would be different. On the other hand, it's only the stability of physical laws across these vast distances that allows us to study and understand planets and galaxies and the geology of Mars. So maybe it's a wash.)
Freddie Gray's death on April 19 leaves many unanswered questions. But it is clear that when Gray was arrested in West Baltimore on the morning of April 12, he was struggling to walk. By the time he arrived at the police station a half hour later, he was unable to breathe or talk, suffering from wounds that would kill him.*
Gray died Sunday from spinal injuries. Baltimore authorities say they're investigating how the 25-year-old was hurt—a somewhat perverse notion, given that it was while he was in police custody, and hidden from public view, that he apparently suffered injury. How it happened remains unknown. It's even difficult to understand why officers arrested Gray in the first place. But with protestors taking to the streets of Baltimore since Gray's death on Sunday, the incident falls into a line of highly publicized, fatal encounters between black men and the police. Meanwhile, on Tuesday, a reserve sheriff's deputy in Tulsa, Oklahoma, pleaded not guilty to a second-degree manslaughter charge in the death of a man he shot. The deputy says the shooting happened while he was trying to tase the man. Black men dying at the hands of the police is of course nothing new, but the nation is now paying attention and getting outraged.
In her new book No One Understands You and What To Do About It, Heidi Grant Halvorson tells readers a story about her friend, Tim. When Tim started a new job as a manager, one of his top priorities was communicating to his team that he valued each member’s input. So at team meetings, as each member spoke up about whatever project they were working on, Tim made sure he put on his “active-listening face” to signal that he cared about what each person was saying.
But after meeting with him a few times, Tim’s team got a very different message from the one he intended to send. “After a few weeks of meetings,” Halvorson explains, “one team member finally summoned up the courage to ask him the question that had been on everyone’s mind.” That question was: “Tim, are you angry with us right now?” When Tim explained that he wasn’t at all angry—that he was just putting on his “active-listening face”—his colleague gently explained that his active-listening face looked a lot like his angry face.
A magnitude 7.8 earthquake struck Nepal early on Saturday, centered 10 miles below the surface, less than 50 miles from the capital of Kathmandu. At least 1,100 are already reported to have been killed by the quake and subsequent avalanches triggered in the Himalayas. Historic buildings and temples were destroyed, leaving massive piles of debris in streets as rescue workers and neighbors work to find and help those still trapped beneath rubble. Below are images from the region of the immediate aftermath of one of the most powerful earthquakes to strike Nepal in decades. (Editor's note, some of the images are graphic in nature.)
Four hours after learning about Saturday's devastating earthquake in Nepal, I received a Facebook notification I had never seen before: Sonia, a journalist friend based in northern India, was "marked safe." An hour later, the same notification about a different friend popped up. Then another. Soon, several of my friends wrote that they, too, had learned via this strange new notification that their friends in Nepal were okay.
A few hours later, the mystery was solved. On Saturday afternoon, Facebook CEO Mark Zuckerberg announced on his timeline that the notifications came from Safety Check, a service the company launched last fall. "When disasters happen, people need to know their loved ones are safe," he wrote, "It's moments like this that being able to connect really matters."
Where did it come from, and what are its intentions? The simplicity of these questions can be deceiving, and few Western leaders seem to know the answers. In December, The New York Times published confidential comments by Major General Michael K. Nagata, the Special Operations commander for the United States in the Middle East, admitting that he had hardly begun figuring out the Islamic State’s appeal. “We have not defeated the idea,” he said. “We do not even understand the idea.” In the past year, President Obama has referred to the Islamic State, variously, as “not Islamic” and as al-Qaeda’s “jayvee team,” statements that reflected confusion about the group, and may have contributed to significant strategic errors.
Lots of conservatives talk a good game about how citizens should resist federal control and devolve power to local governments. Few of them are willing to put their convictions into action in quite the same way that Sheriff Joe Arpaio is.
The man who calls himself "America's toughest sheriff" was already in trouble with Uncle Sam, on trial for contempt of court in a U.S. district court. It was only once that was under way that Arpaio and his lawyer apparently had the idea to sic a private investigator on the wife of the federal judge hearing his case. That shows toughness. It shows a willingness to use unorthodox tactics to resist federal interference. It's also not especially bright.
Reporters in the courtroom describe a somewhat shocking scene. Lawyers had completed their questioning when Judge Murray Snow announced he had some questions for Arpaio. After a series of queries, Snow asked: "Are you aware that I've been investigated by anyone?"
After more than a year of rumors and speculation, Bruce Jenner publicly came out as transgender with four simple words: “I am a woman.”
“My brain is much more female than male,” he explained to Diane Sawyer, who conducted a prime-time interview with Jenner on ABC Friday night. (Jenner indicated he prefers to be addressed with male pronouns at this time.) During the two-hour program, Jenner discussed his personal struggle with gender dysphoria and personal identity, how they shaped his past and current relationships and marriages, and how he finally told his family about his gender identity.
During the interview, Sawyer made a conspicuous point of discussing broadly unfamiliar ideas about gender and sexuality to its audience. It didn't always go smoothly; her questions occasionally came off as awkward and tone-deaf. But she showed no lack of empathy.
Today was the latest installment of the never-ending Clinton scandal saga, but it won’t be the last. Yet in some ways, the specifics are a distraction. The sale of access was designed into the post-2001 Clinton family finances from the start. Probably nobody will ever prove that this quid led to that quo … but there’s about a quarter-billion-dollar of quid heaped in plain sight and an equally impressive pile of quo, and it’s all been visible for years to anyone who cared to notice. As Jonathan Chait, who is no right-wing noise-machine operator, complained: “The Clintons have been disorganized and greedy.”
“All of this amounts to diddly-squat,” pronounced long-time Clinton associate James Carville when news broke that Hillary Clinton had erased huge numbers of emails. That may not be true: If any of the conduct in question proves illegal, destroying relevant records may also have run afoul of the law.
Our patient—we’ll call him W.B.—is a 56-year-old father of three who, until last year, had always been healthy. He had worked his entire life, in jobs ranging from automotive repair to sales, taking great pride in providing for his family, even though doing so had recently meant combining three part-time positions. All of that ended in February 2014, when he was diagnosed with amyotrophic lateral sclerosis, or ALS, commonly known as Lou Gehrig’s disease. A neurodegenerative disease characterized by progressive muscle weakness, ALS leads to the loss of all voluntary movement, difficulty breathing, and, in the end, death.
W.B.’s life was turned upside down by the diagnosis. But once the initial shock passed, he began researching his condition intensively. He learned that he was unlikely to survive five years, and that in the meantime his quality of life would diminish dramatically. With limited options, many patients retreat. But, quite bravely, W.B. had other ideas. After much consideration, he decided that if he was going to die, he would like to try to save another person’s life in the process, even if that person was a stranger. And so last May he approached the University of Wisconsin’s transplant program, where we are surgeons, as a prospective organ donor.
