Scientists studying decades of pygmy sperm whale strandings have uncovered three previously unknown types of Helicobacter bacteria hiding in the animals’ stomachs。 All four infected whales showed serious digestive damage, including inflammation, ulcers, scarring, and parasite infestations, although the bacteria were not confirmed as the cause of de

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

A naturally occurring compound found in foods such as wheat germ, mushrooms, and aged cheese may help older adults build stronger protection after vaccination。 In a small pilot trial, researchers gave spermidine supplements to adults over 65 following their third COVID-19 vaccine dose。 The biggest improvements appeared among people whose immune sys

A new particle detector called PLATON could replace millions of tiny detector components with a single block of light-producing material。 Using a light-field camera, highly sensitive photon sensors, and AI, it reconstructs particle paths in fast, detailed 3D。 Simulations suggest it could match or surpass today’s best detectors while being far easie

Over the past few months, our team has been building more and more slidedecks using web frontend technologies with coding harnesses like Claude Code, but a common complaint is to make even small edits we need to edit the code either manually or via the harness。To avoid this loop, I ended up creating Bento, a single HTML file with everything you nee

Researchers have created cosmic dust from scratch by recreating space-like conditions inside glass tubes。 The dust contains complex carbon-rich molecules built from elements essential to life and produces infrared signals similar to real material found in space。 By studying these laboratory samples, scientists can explore how organic chemistry unfo

Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone。 The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space。 Located 48 light-years away, the world may have preserved its atmosphere for billions of years, making it a promising target in the search for potenti

There’s a debate going on in the Trump administration over how to handle increasingly powerful Chinese AI models

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

Dying Sun-like stars may not fade away quietly。 As blobs of gas erupt unevenly from their swollen surfaces, each burst gives the star a tiny push in the opposite direction。 Thousands of these random kicks could eventually break apart distant stellar pairs or, in rare cases, drive two stars into a violent collision

Elon Musk and the online right convinced themselves that Christopher Nolan’s “woke” epic would go down in flames。 Now they’re crashing out

An Instagram post turned one California student newspaper into a free-speech flash point。 The students say they were just doing their homework

Google’s parent company, which has spent heavily on artificial intelligence, also showed growth across its businesses, particularly in cloud computing

A deal would underline how scarce computing power is for artificial intelligence development, and could create a new business for Meta

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

For Meta, the move was a reprieve after it and YouTube were found guilty in another case in March of negligence and personal injury for their platforms’ addictive features

Dealerships installed alarms in millions of vehicles—and left them in even if the buyer didn’t want them。 Now researchers warn they can be hacked to unlock, track, and disable cars

Several Chinese businesses associated with the ebike brand Aipas settled a lawsuit with Amazon and the safety certification company UL in July

A new type of malware can worm deep into AI coding systems to steal data and logins—and can flip a “death switch” to destroy files and keep out real users
