AI pragmatists: How language teachers are navigating AI with nuance‎

A pervasive narrative has taken hold in education: generative AI (genAI) is an unstoppable force, and educators must adapt or be left behind.

Flux pathway reveals why mussel-like liquid phase separation can happen in seconds‎

Have you ever wondered how mussels instantly glue themselves to rocks, allowing them to survive the crushing force of ocean waves? They complete this process in under 30 seconds. Yet, in a laboratory, replicating this process of molecular self-assembly, known as liquid-liquid phase separation (LLPS), typically takes dozens of minutes, if not hours. A research team of The Hong Kong University of Science and Technology (HKUST) has recently solved this long-standing puzzle using large-scale molecular dynamics simulation and theoretical analysis, revealing the secret to nature's incredible speed and providing implications for instant biocompatible surgical glues.

Why the Persian Gulf has more oil and gas than anywhere else on Earth‎

It has been said that Persian Gulf countries are both blessed and cursed by their vast oil and gas reserves. Geologic forces over millions of years have meant the region is an energy-rich global flash point, as it is now with a war underway that's causing a global energy crisis.

Hackers meet their match: New DNA encryption protects engineered cells from within‎

Engineered cells are a high-value genetic asset that is key to many fields, including biotechnology, medicine, aging, and stem cell research, with the global market projected to reach $8.0 trillion USD by 2035. Yet the only ways to keep the cells safe are strong locks and watchful guards.

Why the phrase 'Super El Niño' makes Australian climate scientists roll their eyes‎

Frightening headlines predicting a Super El Niño or even a Godzilla El Niño amp up anxiety levels for farmers and residents of bushfire-prone regions.

Oldest dog DNA suggests 16,000 years of human companionship‎

The discovery of the oldest ever dog DNA suggests they have been our best friends for nearly 16,000 years—5,000 years earlier than had previously been thought, new research said Wednesday.

A nanoscale robotic cleaner can hunt, capture and remove bacteria‎

Tiny robots—around 50 times smaller than the diameter of a human hair—open up fascinating possibilities: they enable the controlled manipulation of objects far too small for human hands. This brings us closer to a long-standing dream—the direct interaction with the microscopic world.

Irish bog plant revives ancient remedy as a new weapon vs superbugs‎

Long before we had modern antibiotics to rely on, people often turned to traditional medicines from plants to treat infections.

Astronomers find evidence for three subpopulations of merging black holes‎

Astronomers analyzing gravitational-wave data from the LIGO-Virgo-KAGRA Collaboration have reported that merging binary black holes fall into three distinct categories. The study shows that the three subpopulations have their own characteristic masses, spin behavior, and merger rate that may be linked to different dominant formation mechanisms. The paper outlining their results was submitted to the preprint server arXiv on March 18.

High-resolution imaging captures cavity-induced density waves in a quantum gas‎

A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of cavity-induced density waves induced by laser light in an ultracold quantum gas. Previously, only global signals, such as photon leakage or the peak in energy deposition of a fast charged particle (Bragg peaks), have been used to detect this kind of ordering. Prior to this study, there had been no direct, high-resolution in situ imaging of cavity-induced density-wave order in ultracold gases.
