Scientists used nanoscale gold metamaterials to supercharge heat transfer across tiny gaps, achieving up to four times more energy flow than similar conventional systems。 The breakthrough could lead to better chip cooling, more efficient energy technologies, and a new era of precision heat engineering

Artificial intelligence is expensive to use, many companies discovered。 That has led to a new era of saving costs

Critics saw the move as an underhanded way to steer them toward more costly chips

Why some argue the social media ban could have a profound affect on how young people gain new knowledge and the rest of us move around online

“I deleted it as a test and it came immediately back,” says one government employee

He had retinal tears and bruises from squishing his eyeballs with the gun

The move comes after the company left potentially sensitive data from the initiative exposed internally

Workers at the artificial intelligence company have been puzzled and increasingly concerned by the administration’s move to limit their latest A

Tech companies and authorities are failing women by focusing on nudity rather than consent, says a report by Chayn

A new SETI study suggests we may be overlooking alien signals not because they aren't there, but because their own stars are scrambling them before they escape into space。 Turbulent plasma and powerful stellar storms can spread an ultra-narrow radio transmission across a wider range of frequencies, making it much harder for traditional searches to

A new nature-inspired membrane uses perfectly uniform one-nanometer pores to filter molecules with remarkable precision。 The technology could transform industries such as pharmaceuticals and textiles by reducing energy consumption, improving water reuse, and delivering separation performance far beyond current filters

Scientists discovered that kombucha’s flavor, chemistry, and antioxidant activity vary dramatically depending on the tea used to make it。 Green and oolong tea kombuchas emerged as the most biologically active, while fermentation transformed each tea into a distinctly different beverage

The driver told investigators he was using the vehicle’s automated-driver system when the vehicle left the roadway and crashed into a house in Harris County, Texas

Action cameras are perfect for capturing travel adventures, recording social media vlogs, and more。 Make use of these great Prime Day deals

Shiona McCallum visits Fifa HQ in Zurich to see new tech being used in the World Cup

Researchers found that highly drug-resistant bacteria from hospitals are also resistant to glyphosate, a commonly used weedkiller。 The discovery suggests that agricultural herbicides may be helping antibiotic-resistant microbes survive and spread far beyond healthcare settings

Researchers used genome editing to block the production of red pigments in lettuce, causing other beneficial plant compounds to build up instead。 The lettuce continued to grow normally, pointing toward a new way to create crops with customized nutritional profiles

The global cobalt supply chain is more interconnected—and more vulnerable—than previously thought, with disruptions capable of triggering far-reaching cascades across multiple countries and industries。 Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn local shocks into

Public notice of a single "compassionate use" case is odd in every way
