Prof. Erik Demaine speaks with Popular Mechanics reporter Sarah Wells about the surprisingly complex math behind wrapping a present. "If [the wrapping] is a square piece of paper, we know the best [way]," Demaine says. "[But] what if I gave you an eight-and-a-half by eleven rectangle? The answer turns out to be really complicated…And again, this is just wrapping a cube. If you're wrapping a general box, it's going to get even messier. Here, we don't even know the right answer."

A new study co-authored by Prof. Antoinette Schoar finds that the “top Bitcoin holders control a greater share of the cryptocurrency than the most affluent American households control in dollars,” reports Paul Vigna for The Wall Street Journal. “Despite having been around for 14 years and the hype it has ratcheted up, it’s still the case that it’s a very concentrated ecosystem,” explains Schoar.

Prof. Antoinette Schoar and Igor Makarov of the London School of Economics conducted a new study that mapped out every Bitcoin transaction since 2008, reports Fortune reporter Marco Quiroz-Gutierrez. “According to the study, 90% of Bitcoin transactions are not a result of a user buying something with the currency, but rather transactions between a single user’s own crypto accounts,” writes Quiroz-Gutierrez.

Boston Globe reporter Kevin Lewis spotlights how MIT researchers surveyed thousands of Democrats and Republicans to rate the reliability of nonpolitical news headlines. “People genuinely believe that opposing partisans are more gullible, even when that stereotype is costly to them,” writes Lewis. “On the other hand, that stereotype can be corrected with evidence.”

Gizmodo reporter Mack DeGeurin writes that a new study co-authored by MIT researchers finds that just .01% of Bitcoin buyers control around 27% of the 19 million cryptocurrency in circulation. “This tiny concentration of so much wealth means the Bitcoin rich will likely only get richer if the cryptocurrency continues to increase in value,” DeGeurin writes. “It also means power is less dispersed, which could make Bitcoin more susceptible to systemic risk.”

Popular Science reporter Leto Sapunar spotlights the efforts of MIT researchers who are investigating the origins of a fast blue optical transient nicknamed “the Cow.” To research scientist Dheeraj “DJ” Pasham, “this looks like a sign that matter is closely orbiting a ‘newborn’ black hole or a type of neutron star called a magnetar, and the matter shines with x-rays each time it completes a quick orbit,” writes Sapunar.

Forbes contributor Stephanie MacConnell spotlights the work of research affiliate Shriya Srinivasan PhD '20 in a roundup of women under the age of 30 who are transforming U.S. healthcare. Srinivasan is “working on technology that will enable patients to control and even ‘feel’ sensation through their prosthetic limb,” notes MacConnell.

Researchers from MIT and the Berklee College of Music “have started a blockchain platform called RAIDAR, designed to help musicians connect with potential clients (perhaps filmmakers or video game designers who need theme music) and get paid for their work without losing ownership,” reports Newsweek.

Wired reporter Matt Simon spotlights CSAIL’s ‘Evolution Gym,’ a virtual environment where robot design is entirely computer generated. “There’s a potential to find new, unexpected robot designs, and it also has potential to get more high-performing robots overall,” says Prof. Wojciech Matusik. “If you start from very, very basic structures, how much intelligence can you really create?”

STAT reporter Katie Palmer writes that MIT researchers have developed a new machine learning model that can "flag treatments for sepsis patients that are likely to lead to a ‘medical dead-end,/ the point after which a patient will die no matter what care is provided.”

Newsweek reporter Robert Lea spotlights how MIT researchers traced the source of a bright blue cosmic explosion to the birth of a neutron star or black hole. “We have likely discovered the birth of a compact object in a supernova” says research scientists Dheeraj “DJ” Pasham. “This happens in normal supernovae, but we haven’t seen it before because it’s such a messy process. We think this new evidence opens possibilities for finding baby black holes or baby neutron stars.”

Researchers from MIT and other institutions have successfully uncovered the letterlocking technique that Mary, Queen of Scots, used to seal her final letter, reports NPR’s Tien Le. “The spiral lock requires more than 30 steps and involves cutting out a ‘lock,’ often resembling a dagger or sword, out of the blank margin of the letter,” writes Le. “The lock acts as a needle and is sewn through the letter after folding it.”

Gizmodo reporter Isaac Schultz writes that MIT astronomers have found that a black hole or neutron star may have been produced by a burst of stellar light, known as “the Cow." “I think the Cow is just the beginning of what is to come,” explains research scientist Dheeraj “DJ” Pasham. “More such objects would provide a new window into these extreme explosions.”

New Scientist reporter Leah Crane writes that astronomers have found evidence that a large stellar explosion detected in 2018 was likely caused by a dying star that gave birth to a neutron star or small black hole. “People have been suspecting that these kind of extreme explosions could be the birth of black holes or neutron stars, but this is a final piece of evidence that I think really settles the case,” says research scientist Dheeraj “DJ” Pasham.

MIT researchers have uncovered evidence that the creation of a new black hole or neutron star caused a strange blue flash of light in space that was detected in 2018, reports Téa Kvetenadze for Forbes. An explanation for the event was elusive until researchers “focused on the X-rays emitted by the flash and found the Cow was producing a pulse of X-rays every 4.4 milliseconds.”
