A new proof shows what happens tographs before and after a sudden shift called the percolation threshold.
Just as ice melts to water, graphs undergo phase transitions. Two mathematicians showed that they can pinpoint such transitions by examining only local structure.
The UK’s supreme court has ruled that AI cannot be named as an inventor and secure patent rights. It follows earlier decisions from lower courts that reached the same conclusions.
On Wednesday, US computer scientist Stephen Thaler lost his attempt to register patents for inventions he says were created by his AI system, DABUS.
Thaler said DABUS autonomously created a light beacon and a container for food and drink, and entitled to rights over the inventions.
If you ever find yourself aboard a spaceship exploring the profound mysteries of the universe and you have the sudden urge to poop — former NASA astronaut Mike Massimino has some insights for you.
“It requires a lot of training,” Massimino told “The Daily Show” guest host Kal Penn during a recent segment. “You get rendezvous training and robotics training in space, and there would be potty training.”
Because toilets on board NASA spacecraft are unlike Earth-bound commodes, he explained, you will need practice. These space thrones don’t use water but instead use negative air presure to suck away waste like a vacuum.
Sam Altman, CEO of OpenAI, sees the loss of jobs as a natural part of “technological revolution” every 100 to 150 years.
The holiday season means presents galore — but in the case of at-home DNA tests, some gifts may be better left unopened.
As experts told USA Today, the prevalence of self-serve DNA testing has made it much more likely that people discover painful family secrets — for instance, that one or both of your parents are not your genetic relatives — upon getting their results.
For years now, we’ve come across reports about people learning of their parents’ affairs via DNA testing kits from companies like Ancestry or 23andme.

A Brazilian politician admitted to using ChatGPT to craft a law, which a city council later passed without knowing AI was used.
The Blue Origin founder told podcaster Lex Fridman that he didn’t know Elon Musk well but that he must be a very capable leader.
AI is here to enforce Zoom etiquette, apparently.
As The Wall Street Journal reports, a growing number of companies are using AI bots in video meetings to mediate, transcribe, and — yes — etiquette-check participants who may be lecturing or interrupting others. Often, according to the report, the bots are just silent notetakers, there to either summarize the meeting for someone who can’t be there, or keep minutes for the group. In other cases, though, the bots will pipe up to let speakers know whether they might be droning on a bit too much.
“It was like, monologue!” Josh Stir, the senior software development manager for a tax services company, told the WSJ of his experience with a Zoom behavior bot. The AI seemingly thought the software developer was speaking too flatly, urging Stir to raise and lower his pitch in order to maintain the group’s interest.
In its ground state, the helium-8 (8He) nucleus consists of an alpha particle (4He nucleus) and four neutrons. If, before its few-hundred-milliseconds life ends, an 8 He nucleus is nudged into its first 0+ excited state, the four neutrons form two pairs known as dineutron clusters. According to theory, the alpha particle and the two neutron clusters settle into a three-member nuclear analog of a Bose-Einstein condensate. That outcome has now been observed for the first time by Zaihong Yang of Peking University and his colleagues at the RIKEN Nishina Center in Japan [1].
The experiment entailed firing a high-intensity beam of 8 He nuclei at polyethylene and carbon targets. Some collisions excited the nuclei into the sought-after condensate state, which promptly broke up into a helium-6 (6He) nucleus and a single neutron pair. The 6 He nuclei made their way through dipole magnets to drift detectors and plastic scintillators for characterization. The neutrons struck a plastic scintillator whose layered construction made it possible to identify which neutrons were correlated—that is, members of a dineutron cluster—and which were not. The correlated neutron pairs and the scattering count rate’s dependence on energy, angle, and type of target were all consistent with theoretical predictions of the nature of the correlated 8 He excited state.
The 8 He condensate resembles the so-called Hoyle state of carbon-12, which consists of three alpha particles in the condensed state. Astronomer Fred Hoyle predicted the state in 1954 to account for the synthesis of carbon in helium-burning stars. Yang points out that nuclear condensates could also have implications for understanding the structures of exotic nuclei and neutron stars.
