After spending two years on the ocean’s floor, Microsoft’s underwater data center had a much lower server failure rate than land-based data centers.
A robot has addressed the House of Lords for the first time, telling a committee that artificial intelligence can be a ‘threat and opportunity’ to artists.
The robot, named Ai-Da and devised in Oxford by Aidan Meller, gave evidence to the communications and digital committee as part of an inquiry into the future of the arts, design, fashion and music industries and how AI might affect them.
With rapidly developing AI, growing accessibility to super computers and machine learning on the ride, Ai-Da – named after the computing pioneer Ada Lovelace – was created as a ‘comment and critique’ on rapid technological change.
Human brain tissue has been successfully transplanted into the brains of rats using a cutting-edge experimental procedure, say researchers. They envision the achievement as a promising new frontier in medical research.
Groups of living human nerve cells have become integrated into the brains of laboratory rats, creating hybrid brain circuits that can be activated through input from the rats’ senses, the scientists reported Wednesday.
Further, experiments have shown that the human tissue forms a two-way connection within the rat brain, also sending out signals that can potentially alter the rat’s behavior, the researchers said.
Results from two leading dark matter experiments—XENONnT and PandaX-4T—rule out an enigmatic signal detected in 2020 and set new constraints on dark matter particle candidates consisting of light fermions, respectively.
Over the past decade, physicists have repeatedly scrutinized tanks containing tons of liquid xenon, hoping to spot the flashes of light that might indicate a collision between a dark matter particle and a xenon atom (see Viewpoint: Dark Matter Still at Large). Most of these studies were dedicated to detecting so-called weakly interacting massive particles (WIMPs), a leading dark matter candidate with a mass greater than 10 GeV. Now researchers have sifted through a new set of data for a much lighter prize: fermionic dark matter with a mass of a few tens of MeV [1]. Although the team found no signal beyond the expected background level, they have set the strongest constraints yet on models of sub-GeV fermionic dark matter.
The dataset is the first obtained by the PandaX-4T experiment at the China Jinping Underground Laboratory. The PandaX team searched this data for evidence of a beyond-the-standard-model interaction in which a fermionic dark matter particle is absorbed by the nucleus of a xenon atom. After the absorption, the xenon nucleus should recoil while emitting either a neutrino or an antineutrino. The interaction should also cause an energy deposition in the form of photons and electrons, which would register on photodetectors at the ends of the tank. Unlike the scattering of WIMPs, which is predicted to produce a broad-spectrum energy deposition, the absorption by nuclei of fermionic dark matter particles should deposit energy only in a narrow range.
The data collected so far represent the equivalent of exposing 0.6 tons of liquid xenon to hypothetical fermionic dark matter for one year. When PandaX-4T concludes in 2025, it will have achieved a cumulative exposure 10 times greater, generating even stronger constraints on theory.

A normal digital camera can take snaps of objects not directly visible to its lens, US researchers have shown. The “ghost imaging” technique could help satellites take snapshots through clouds or smoke.
Physicists have known for more than a decade that ghost imaging is possible. But, until now, experiments had only imaged the holes in stencil-like masks, which limited its potential applications.

Quantum nonlocality is known to be reducible to quantum uncertainty and steering, but it is unclear whether steering is actually as essential as uncertainty. Here, the authors show that both steering and uncertainty play a role in determining optimal strategies in nonlocal games.
