An existing constipation drug may have an unexpected new use: helping clear the "brain fog" that often lingers after depression。 In a small clinical trial, people with a history of depression who took the medication prucalopride for about a week performed better on tests of memory, attention, and thinking speed than those who received a placebo。 Th
A distant Sun-like star appears to have devoured one of its planets, leaving behind a surprising chemical fingerprint。 Researchers found an unusually high concentration of lithium, a strong sign that planetary material was mixed into the star。 Careful comparisons with dozens of similar stars confirmed the signal is highly unusual, and scientists th
A catastrophic asteroid breakup may have triggered a huge wave of impacts across the inner solar system about 800 million years ago。 The debris was launched from near a gravitational gateway controlled by Jupiter, sending fragments toward Earth, the Moon, and Mars。 The bombardment may explain ancient lunar craters and could have contributed to majo
Scientists have created a programmable optical chip that can slow light on demand, giving engineers far greater control over how optical signals propagate through a circuit。 The technology could provide the delays, synchronization, and buffering functions needed to make light-based computing more practical。 A single chip could eventually perform se
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
Hey HN, Henry & Roman here from Cactus。A small, on-device model is fast and private, but sometimes wrong, but frontier models are getting expensive pretty fast。 So, we post-trained Gemma 4 E2B post-trained to know when it's wrong
A new book claims AI has been built on a flawed assumption dating back to Alan Turing's famous 1950 paper。 Denning argues that the most important parts of human intelligence, including common sense, intuition, culture, and practical know-how, cannot be encoded into computers。 He believes this makes true human-level AI impossible, regardless of how

People spend hours watching videos on their smartphones。 The wider, shorter, and lighter Galaxy Z Fold8 caters to exactly that
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
Ronald Fischer, aka Richard Graydon, was arrested in New York last week
Google’s parent company, which has spent heavily on artificial intelligence, also showed growth across its businesses, particularly in cloud computing
It turns out some of Benjamin Franklin's opinions from 240 years ago are still relevant today
