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
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
NASA is preparing for future astronaut landings on the Moon with an unusually ambitious orbital rehearsal。 During Artemis III in 2027, Orion astronauts will rendezvous and dock separately with prototype lunar landers from Blue Origin and SpaceX, allowing crews and ground teams to test the complex maneuvers needed for later missions
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
There’s a debate going on in the Trump administration over how to handle increasingly powerful Chinese AI models
A giant planet had been hiding inside one of astronomy’s most closely studied planetary systems, concealed by a bright disk of cosmic dust。 Webb revealed Beta Pictoris d through atmospheric traces of carbon monoxide, water vapor, and methane, showcasing a promising new method for finding elusive exoplanets
Researchers in the Gulf of California have documented a dramatic orca behavior never described before。 In two separate encounters, one orca gripped a dead sunfish by the fin while another charged into it at high speed, blasting the carcass into thousands of pieces
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
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
An Instagram post turned one California student newspaper into a free-speech flash point。 The students say they were just doing their homework
A deal would underline how scarce computing power is for artificial intelligence development, and could create a new business for Meta
Elon Musk and the online right convinced themselves that Christopher Nolan’s “woke” epic would go down in flames。 Now they’re crashing out
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
Google’s parent company, which has spent heavily on artificial intelligence, also showed growth across its businesses, particularly in cloud computing
Aggressive training techniques sharpens threat of bad behavior by leading models
For Meta, the move was a reprieve after it and YouTube were found liable in another case in March of negligence and personal injury for their platforms’ addictive features
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
In a first, Apple software will influence the way a new line of electric vehicles made by Ford Motor operates, and other automakers may follow
It follows a review by the regulator in May that criticised the platform for not being "safe enough" for children
