LEDs are already pretty tiny, but they just got a whole lot smaller. Researchers at the University of Washington have built what they say are the “thinnest-possible LEDs” — tiny lights that measure just three atoms thick. “Such thin and foldable LEDs are critical for future portable and integrated electronic devices,” Xiaodong Xu, co-author of a paper on the research that was published over the weekend in Nature Nanotechnology, says in a statement. At three atoms thick, the researchers’ LEDs are said to be 10 to 20 times thinner than conventional LEDs, opening up a number of potential new uses for them.

Scientists say that something mysterious punched gigantic, cosmic “bullet holes” in parts of the Milky Way.
There’s a string of holes in a long stream of stars called GD-1 that suggests that some yet-undiscovered thing blasted its way through, according to research presented to the American Physical Society last month and first reported by Live Science. Harvard-Smithsonian astrophysicist Ana Bonaca, the scientist who discovered the cosmic crime scene, suspects that the gigantic “bullet holes” may have been carved out by invisible dark matter.

New York City is set to get a new radiation-treatment center, nearly a decade in the making, that uses proton beams to treat cancerous tumors.
Called the New York Proton Center, it is a for-profit partnership of Memorial Sloan Kettering Cancer Center, Montefiore Health System and Mount Sinai Health System, managed by the ProHEALTH company. Financing for the center was provided in part by the hospitals.

BENSALEM, Pa. (CBS) — It could be the difference between life and death. A mobile rescue squad was unveiled Thursday in Bucks County.
Every 40 seconds, someone in the United States has a stroke. Survival depends on quick treatment. Now, instead of racing to the hospital, a mini, specialized hospital on wheels can come to you.
“We’re the first university medial center in our region to have this,” Jefferson neurosurgeon Dr. Robert Rosenwasser said.
An ever-increasing number of research groups are developing tiny robots, capable of performing targeted drug-delivery inside the body. One of the latest such devices incorporates a flapping whale-flukes-like tail, along with wings that fold up or down as needed.
These studies show that older adults who frequently pick up a puzzle tended to have the short-term memory capacity of someone eight years their junior and the grammatical reasoning of someone ten years younger.
“We hope this will encourage people to consider how they challenge their brain on a regular basis, and perhaps consider taking up puzzles or evidence-based brain training games as part of a lifestyle approach to keep their brains healthy,” Corbett tells Inverse.
Corbett’s study is one of a few showing that frequent engagement with puzzles has lasting effects on memory and cognitive decline, the slow loss of memory and other problem-solving skills that accompany aging (and is also a feature of brain diseases like Alzheimer’s). Other studies include the Bronx Aging study, which showed that dementia patients who did crossword puzzles started to lose their memory about 2.54 years later than those who didn’t do crosswords.
Decades after Isaac Asimov first wrote his laws for robots, their ever-expanding role in our lives requires a radical new set of rules, legal and AI expert Frank Pasquale warned on Thursday.
The world has changed since sci-fi author Asimov in 1942 wrote his three rules for robots, including that they should never harm humans, and today’s omnipresent computers and algorithms demand up-to-date measures.
According to Pasquale, author of “The Black Box Society: The Secret Algorithms Behind Money and Information”, four new legally-inspired rules should be applied to robots and AI in our daily lives.
