Neutrinos are known to have tiny masses. A new result proclaims the subatomic particles to be even tinier still. The electrically neutral particles, produced in radioactive decays and in reactions in the sun and elsewhere in the cosmos, have a mass of less than 0.45 electron volts, physicists report in the April 11 Science. The result, from the Karlsruhe Tritium Neutrino, or KATRIN, experiment slashes the experiment’s previous upper limit for neutrino mass by nearly half. Sign up for our newsl

Physicists have placed a new limit on how big the elusive neutrino can be—one of the universe’s smallest known particles—a limit that makes other subatomic particles look as big as black holes by comparison. In a new result published this week in Science, researchers have put a new upper limit on the mass of this itsy-bitsy particle: no more than 0.45 electron volts (eV). For context, that’s less than one-millionth the mass of an electron, which clocks in at a comparatively gargantuan 511,000 e

In the mid 19th century, a strange idea was growing heavy in the ether: There might be dimensions beyond the three we experience. To some—including eminent scientists of the day—these were the realms of spirits and the supernatural, accessed through tabletop seances. To Charles Hinton, a British mathematician and science-fiction writer at the time, it was something that could be puzzled out, modeled in things like his “tesseract” four-dimensional cube. In the intervening century and a half, spi

A team of researchers just introduced a new way of detecting gravitational wave sources that they posit could vastly improve precision of detections and expedite the detection of such enigmatic events. The team’s research, published today in the journal Nature, outlines an algorithm to study neutron star mergers’ gravitational wave emissions. Once identified, astronomers around the world could be notified of the event, allowing experts to collect as much information as possible about the fleeti

Neut is a functional programming language with static memory management. Its key features include: Full λ-calculus support Predictable automatic memory management The absence of annotations to the type system when achieving both of the above Neut doesn't use GCs or regions. Instead, it takes a type-directed approach to handle resources. Like the following: // the obligated hello world define hello(): unit { print("Hello, world!

New York's law requiring Internet service providers to offer broadband for $15 or $20 a month has spurred legislative efforts in other states to guarantee affordable service for people with low incomes. So far, legislators in Vermont, Massachusetts, and California have proposed laws inspired by the New York requirement. Christopher Morrow, a newly elected Democratic state legislator in Vermont, introduced a bill on January 29 that is modeled on New York's law. "Affordability is a big issue in V
