China’s space station reaches record-low atomic temperature

An experiment aboard China’s space station produced atoms at a reported record-low temperature of about 10 trillionths of a kelvin, or roughly 10⁻¹² K. Orbiting Earth reduces the influence of gravity, allowing researchers to study atomic behavior under unusual conditions. In the station experiment, that environment was used

Proposed Technique Reads Quantum Information with High Accuracy

A proposed technique could make quantum computing more practical by reading information from delicate qubit states without destroying them. Instead of relying on a measurement process that may alter the state being examined, the method detects an electrical signal produced by the qubit itself. In simulations, the approach achieved accuracy

SLAC X-ray measurements identify the distinct magnetic signature of an altermagnet

Scientists at the Stanford Linear Accelerator Center have produced what Science Daily describes as conclusive evidence of a third type of magnetism, known as altermagnetism. Their result comes from specialized X-ray measurements that revealed a distinctive magnetic signature in altermagnetic materials, separating their behavior from that of conventional magnets.

Recent Observations Suggest Mars’s Volcanoes Are Dormant, Not Extinct

Scientists have long suspected that Mars is geologically “dead,” with its volcanic activity largely considered a feature of its distant past. However, recent spacecraft observations suggest another possibility: the Red Planet’s volcanoes may be sleeping rather than permanently inactive. The findings point to a more geologically dynamic Mars than

China Expands AI-Controlled Research Laboratories

China is expanding laboratories that operate with artificial intelligence, according to a report in The Economist. The development appears to be part of China’s broader effort to build its AI capabilities with an eye on U.S. technological leadership. The report’s available description does not specify which laboratories

Mechanical pressure changes the magnetic behavior of altermagnets

A small mechanical squeeze can sharply change the magnetic properties and electrical behavior of altermagnets, according to researchers studying these exotic materials. The finding shows that physical pressure can be used to modify material behavior in ways that may be useful for designing faster, more energy-efficient electronic devices. It

Researchers confirm altermagnetism as a distinct form of magnetism

For most of the past 90 years, magnetism has been described in two broad categories. Researchers at the Stanford Linear Accelerator Center have now confirmed a third: altermagnetism. Using specialized X-ray techniques, the team detected a unique magnetic signature in altermagnetic materials. This signature distinguishes their behavior from that
