It looks like 3D printing is taking over the world, little by little. Uses for it range from creating a doll clone of yourself to printing meat (yes, for actual consumption). But the University Medical Center Utrecht in the Netherlands has found yet another way to implement the new technique: Doctors are reporting that the world's first 3D skull implant was a success.
The 23-hour surgery was performed on a 22-year-old woman who suffered from severe headaches, loss of vision, and loss of motor coordination due to a thickening of her skull. Dr. Bon Verweij, the neurosurgeon on the case, said in a press release that it was only a matter of time before other essential brain functions would have atrophied.
The surgery took place three months ago, but due to the patient's recovery time, doctors are only just now calling it a success.
"The patient has fully regained her vision, she has no more complaints, she's gone back to work and there are almost no traces that she had any surgery at all," Verweij said.
3D printing technology has served as a major advancement in these types of surgeries. "We used to create an implant by hand in the operating theater using a kind of cement, but those implants did not have a very good fit," Verweij said. "Now we can use 3D printing to ensure that these components are an exact fit. This has major advantages, not only cosmetically but also because patients often have better brain function compared with the old method." Hayley Munguia
The Obamas have decided to stay in Washington, D.C., for a couple more years — well, not Malia — so youngest daughter Sasha can finish up high school. "Our decisions has actually presented a bit of a dilemma, because traditionally presidents don't stick around after they're done," President Obama said at Saturday night's White House Correspondents' Dinner. That was the set-up for a pre-recorded video in which Obama broods about his post–White House plans. In the short film, Obama seeks advice from Vice President Joe Biden, takes advice from former House Speaker John Boehner, tells NBC's Chuck Todd to do something rude to himself, and pokes fun at his own "mom jeans."
The whole video is good, but the highlight is probably when Obama decided he had to get his Washington, D.C., driver's license and visited the local DMV. "What's the name?" the DMV employee, Kat, asked when Obama's number was finally called. "Barack Hussein Obama," he said. "Yikes," she grimaced. "Well, since you don't have a driver's license, you're going to need a birth certificate." If you remember the whole "birther" flap, you can probably guess where that it going, and they go there with pretty impressive acting chops and impeccable comedic timing. Watch below. Peter Weber
Children ages 1-3 have shot somebody with a gun they found more than once a week in the U.S. this year, and in most cases, they were the victim, too. According to a Washington Post count, toddlers were involved in at least 23 shootings between Jan. 1 and the April 29. In 18 of those cases, the children shot themselves, and nine of those toddlers died. In the other five cases, the toddler shot another person, and two died — on April 27, a 2-year-old boy fatally shot his mother in the car after a gun slid out from under the front seat, and in February, a 3-year-old boy shot and killed his 9-year-old brother in Alabama.
The rate of toddler-involved shootings is not uniform across states, with Georgia notching eight such shootings since the beginning of 2015, Texas and Missouri tied for second place with seven shootings, while Michigan and Florida each have six. There are probably some legal and cultural reasons for the variations in toddler shootings, but it's "still largely a guessing game," says The Post's Christopher Ingraham. "And it's a game made much more difficult by Congress' efforts to restrict the type of gun research that agencies such as the Centers for Disease Control and Prevention are allowed to conduct."

The annual White House Correspondents' Dinner is an odd tradition, where the president of the United States and a carefully selected comedian roast the rich, famous, and powerful people in the room, including the president, and also members of the news media, while the whole world can watch on C-SPAN. President Obama's zingers have generally been met with positive reviews — except by Donald Trump — and Saturday's roast was no exception. Larry Wilmore, this year's featured comedian, bombed. Or, at least, his routine wasn't universally embraced inside the room (CNN's Wolf Blitzer gave Wilmore some hard stares, while Don Lemon gave him the finger).
But as The Washington Post's Callum Borchers (and lots of people on Twitter) pointed out, another certain comedian who hosted a show following The Daily Show at Comedy Central also was met with uncomfortable, sometimes sparse laughter when he hosted the "nerd prom" back in 2006.
Larry Wilmore going full Colbert-at-#WHCD tonight. No one in the room laughing but everyone outside is.

And Stephen Colbert has done pretty well for himself. More to the point, Borchers notes, "in hindsight, few would disagree with the underlying critique of Colbert's satire," that President George W. Bush had invaded Iraq on false pretenses and the media had not asked enough questions or challenged Bush adequately in the lead-up to the invasion. Wilmore's most trenchant critiques on Saturday were about race — which wouldn't be much of a surprise to anyone who's watched Wilmore's Nightly Show — though he also got in the expected jabs at the 2016 candidates as well as Obama. Will Wilmore's performance age well? You can judge his 22-minute set below. Peter Weber
On Monday, Craig Wright released evidence purporting to prove that he is "Satoshi Nakamoto," the pseudonymous inventor of digital currency Bitcoin. Wright, an Australian computer scientist and entrepreneur, told BBC News and The Economist that he was coming forward reluctantly. "I have not done this because it is what I wanted," he told BBC News. "It's not because of my choice." Wired and Gizmodo claimed Wright was the Bitcoin founder in December, though there has been a history of mispointed finders: A March 2014 report in Newsweek wrongly identified Dorian S. Nakamoto, a California physicist, as the Bitcoin founder.
Along with the BBC and The Economist, Wright shared his evidence beforehand with GQ. It includes digital coins that only Satoshi Nakamoto would have, including "blocks used to send 10 Bitcoins to Hal Finney in January  as the first Bitcoin transaction," Wright said, referring to a renowned cryptographer he says helped turn Bitcoin into reality. "I was the main part of it, but other people helped me," he added. BBC News spoke with Bitcoin experts who believe that Wright really is Nakamoto, but The Economist is a little skeptical.
"Our conclusion is that he could well be Mr. Nakamoto, but that nagging questions remain," The Economist said. "In fact, it may never be possible to prove beyond reasonable doubt who really created Bitcoin. Whether people, particularly Bitcoin cognoscenti, actually believe Mr. Wright will depend greatly on what he does next, after going public." Wright did tell The Economist where he came up with the name, citing the 17th century Japanese philosopher and merchant Tomonaga Nakamoto, a free trade proponent, though he wouldn't reveal where "Satoshi" came from ("Some things should remain secret," Wright said).
The Economist also points out that the Bitcoin community is enmeshed in a big debate about the direction the cryptocurrency should take, and that if Wright is accepted as Nakamoto, "his return from obscurity would most certainly change the dynamics of the debate about Bitcoin’s future direction." You can watch Wright talk to BBC News below. Peter Weber
An Illinois woman is suing Starbucks on behalf of all customers whose cups runneth over with ice.
Stacy Pincus filed a class action lawsuit last week in Northern Illinois Federal Court, court documents say, claiming that so much ice is put into cold drinks that Starbucks customers are cheated out of liquid and paying for more product than what they actually receive. "The word 'beverage' is defined as a 'drinkable liquid,'" the suit says. "Ice is not a 'beverage' by definition. Accordingly, Starbucks actually gives the customer much less beverage in the cold drinks they order and pay for."
The lawsuit maintains that the cups are filled with extra ice so Starbucks can make more money "to the detriment of consumers who are misled by Starbucks' intentionally misleading advertising practices." Pincus says the suit is on behalf of any customer who has purchased a cold drink from Starbucks within the past decade, NBC News reports, and it also offers Starbucks a free suggestion: Start using bigger cups so the advertised amount of liquid can be served, along with the ice. Starbucks told TMZ if a customer isn't pleased with the drink they receive they can ask for a new one, but their guests "understand and expect that ice is an essential component of any 'iced' beverage.'"

Climbers making their way up the Shishapangma mountain in Tibet have found the bodies of famed mountaineer Alex Lowe and cameraman David Bridges, who died in an October 1999 avalanche.
— Global Issues Web (@globalissuesweb) May 2, 2016
Lowe, 40, and Bridges, 29, planned to climb up Shishapangma, the 14th-highest mountain in the world, then ski down it. At 19,000 feet, as they scouted routes, they spotted snow falling down from 6,000 feet above. Their friend, elite climber Conrad Anker, survived the avalanche. In a statement, Lowe's widow, Jenni Lowe-Anker, said the remains were discovered in a partially melted glacier, and after the climbers described to Anker the clothing and backpacks found with the bodies, he concluded they were Bridges and Lowe. The pair were "captured and frozen in time," Lowe-Anker said. "Sixteen years of life has been lived and now they are found. We are thankful."
Lowe was seen as the world's greatest mountain climber at the time of his death, and he twice reached the summit of Mount Everest and scaled Nepal's Kwangde and Kusum Kanguru. Lowe-Anker and Anker married in 2001, and run the Alex Lowe Charitable Foundation from Montana. Anker told Outside magazine that he has not seen any photographs of the remains, but is convinced they belong to Lowe and Bridges. Catherine Garcia
On Sunday, Sen. Bernie Sanders held a news conference at the National Press Club in Washington, outlining his case for why Democratic superdelegates should abandon Hillary Clinton and side with him. His first argument, which he makes frequently, is that polls show him beating Donald Trump by wider margins than Clinton in a hypothetical head-to-head matchup. "They're going to have to go into their hearts, and they are going to have to ask, do they want the second strongest candidate to run against Trump or do they want the strongest candidate?" Sanders said.
Sanders' second argument was that he is "entitled" to the support of superdelegates in states he won by large margins, using Washington State as an example — he won the caucus with 73 percent of the vote, but 10 Washington superdelegates have backed Clinton while none have backed him. "I would ask the superdelegates from the state of Washington to respect the wishes of the people in their state," he said. Even if he flipped all the superdelegates in the 11 states his campaign listed, plus won the uncommitted ones, The Washington Post noted, Sanders would net 77 superdelegates, barely denting Clinton's current 520-39 lead. There are 719 superdelegates (including Sanders himself, but not Hillary Clinton), and they can vote for either candidate.
In the pledged delegate count, Clinton is leading Sanders by 327 delegates, according to the Associated Press tally, meaning Sanders has to win 65 percent of the remaining delegates to catch up with Clinton in pledged delegates. At Sunday's news conference, a reporter asked Sanders senior adviser Tad Devine if the Sanders plan to win by poaching Democratic Party insiders was "strange," given his anti-Establishment campaign message. "Can I use 'ironic' instead of 'strange?'" Devine replied. Peter Weber
