Non-Hermitian geometry reveals when quantum amplification depends only on start and end points‎

In quantum mechanics, the geometry of quantum states has emerged as a powerful framework for understanding phenomena ranging from electrical conductivity to superconductivity. One research direction aims to extend these geometric concepts to non-Hermitian quantum mechanics—where systems can exchange energy with their environment—including the generalization of the Berry phase, a key geometric quantity, to the non-Hermitian case.

Research team cuts cost of building reconstituted cell-free systems by 95%‎

A research team led by Professor Joongoo Lee in the Department of Chemical Engineering at POSTECH (Pohang University of Science and Technology) has developed an automated, modular method for assembling reconstituted cell-free systems, which are test-tube systems that can produce proteins outside living cells.

Coastal and estuarine carbon removal technique may backfire when pushed too far‎

Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that undermine the process.

Saturday Citations: Predicting earthquakes; two types of water; observing event horizons‎

Howdy, pards, here's a quick roundup of the week's science news: Moose, previously thought to be a transplanted species, are actually native to Colorado. A digital twin of a two-year-old child's brain revealed neural signatures linked to autism. And a new gel treatment for severed spinal cords restored mobility in lab animals.

Lamprey brain atlas reveals 450-million-year blueprint of vertebrate brains‎

What did the very first complex vertebrate brain look like? To find out, scientists turned to an unlikely time traveler: the lamprey, a jawless, eel-like fish whose body plan has barely changed in roughly 360 million years.

Swiss glaciers facing drastic loss from heat wave: Expert‎

Swiss glaciers are set to lose an enormous amount of ice due to the heat wave battering Europe, the head of Glacier Monitoring in Switzerland (GLAMOS) told AFP.

New driving model predicts split-second crash avoidance with humanlike accuracy‎

Scientists at Delft University of Technology, in collaboration with Waymo, have developed a new model that predicts with high accuracy how human drivers respond to dangerous traffic situations. For the first time, different types of collision avoidance behavior are combined into a single model. The results will be published on 10 June in Nature Communications. Waymo is already using the model to compare the performance of its autonomous vehicles with that of human drivers.

The bond between humans and dogs remains remarkably consistent across societies, cross-cultural study reveals‎

A new study by an international research team led by Friedrich Schiller University Jena and the Max Planck Institute for Evolutionary Anthropology (Leipzig) has revealed striking similarities in the way humans and dogs interact in very different societies. The research is published in the journal Scientific Reports.

UK sets new June temperature record for third day in a row: Met Office‎

The UK broke the record for a June temperature for the third day in a row on Friday, the Met Office weather agency said, as a sweltering heat wave strained schools and hospitals and drove down business.

Primate evolution kept aging rates stable for 25 million years despite lifespan gaps‎

Biologists group animals with similar traits into broad categories called orders. Despite their similarities, animal species in the same order can have very different average lifespans.
