A new theoretical study offers a possible explanation for how the Universe can grow more complex without violating the second law of thermodynamics。 Using a quantum gravity framework called Gravity from Entropy, mathematician Ginestra Bianconi found that the Universe’s total entropy may rise as space expands, even while entropy within each unit of
A quantum problem once described as impossible for classical computers has now been solved using relatively modest hardware。 Researchers used tensor networks to compress the overwhelming wave function created by hundreds of entangled qubits, allowing some calculations to run on a laptop。 Their results matched both theoretical predictions and simula
Miniature brain models grown from patients’ cells revealed striking differences in how Alzheimer’s-related tissue responds to an antidepressant。 The organoids and the particles they release could eventually guide more personalized treatments and provide new clues for diagnosing the disease
Ancient fern savannahs may have transformed parts of Europe into a wildfire-prone inferno during the end-Triassic mass extinction。 New fossil evidence suggests the ferns repeatedly regrew after fires, creating fresh fuel that helped prolong the devastation
Scientists have found a way to revive vancomycin, a powerful antibiotic that some dangerous bacteria have learned to resist。 Instead of creating an entirely new drug, researchers paired vancomycin with a small molecule called pghi-4, which blocks a bacterial enzyme linked to resistance。 The combination restored the antibiotic’s ability to kill drug
As Google incorporates more artificial intelligence into search, people are spending more time on Google。 Some website operators are crying foul
MIT engineers have found a way to give chip-based lidar a wider, clearer view without relying on moving parts。 Their design uses differently shaped antennas that can sit close together without scrambling one another’s signals。 In tests, the system sharply reduced interference while steering a single precise beam across a broad field of view
文丨刘士武 Bilibili World 2026开幕当天，我和同事果脯从国家会展中心走进展馆逛了一大圈后，发现今年BW确实和以往有所不同。 我们在4馆“BW游先看”展位前停下，那是果脯刚逛过一轮主舞台、回到试玩区的瞬间。他问了一句：“你说B站游戏今年是不是在悄悄变化
