Researchers developed a Wordle-solving strategy that succeeds 99% of the time by focusing on information gain rather than likely answers。 The method uses Shannon entropy to identify guesses that reveal the most about the hidden word。 Each guess is designed to slash uncertainty and narrow the possibilities faster
Quick framing, since the post is long: I did robotic manipulation research at OpenAI from 2017–2020, and the tabletop setup back then cost roughly 10x this one and took a team to run。 This project is me testing whether a single person can now do meaningful work on the same class of problems: starting with physical and software setup。A few decisions
Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world。 Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news
A new study suggests Southern California's major fault system is more stressed than at any point in the last 1,000 years。 Researchers found that the Cajon Pass, where the San Andreas and San Jacinto faults meet, could act as an “earthquake gate” that determines whether a future rupture spreads across both faults。 Current conditions resemble those t
A bold claim that the universe’s accelerating expansion was an illusion has been put to the test—and failed。 Researchers found that the study behind the controversy made key mistakes when analyzing supernova data。 After revisiting the evidence, astronomers concluded that cosmic acceleration remains as strong as ever
Deep beneath the ground in China, the massive JUNO neutrino observatory has delivered its first major scientific breakthrough, achieving one of the most precise measurements yet of how elusive neutrinos change as they travel。 Using just 59 days of data, researchers sharply improved measurements of key neutrino properties, boosting confidence that J
A new study found that chronic wasting disease can sometimes spread silently, with infectious prions present even in animals that show no symptoms。 While there is no confirmed human risk, researchers say the disease’s ability to evolve and spread across species warrants close attention
A clever nanoscale redesign may have solved one of superconductivity’s biggest problems。 Researchers in Sweden discovered that by subtly sculpting the surface beneath an ultrathin superconducting material, they could make it stay superconducting at higher temperatures and under much stronger magnetic fields
Scientists have taken a surprising step toward unlocking regeneration in mammals, showing that the ability to rebuild complex body parts may not be lost after all—it may simply be switched off。 Using a two-stage treatment, researchers redirected the body’s normal healing response away from scar formation and toward regrowth, successfully restoring
Plague was already a deadly killer 5,500 years ago, long before cities, farming, or the rat-infested conditions usually linked to historic outbreaks。 By analyzing ancient DNA from hunter-gatherer cemeteries in Siberia, researchers discovered early plague strains in nearly 40% of the individuals studied and found evidence of rapid family-based outbr
A new technique could solve one of the biggest challenges in making future computer chips from ultrathin materials。 Researchers found that coating molybdenum disulfide with oxygen or fluorine lets manufacturers remove just the top layer of atoms much more safely during plasma processing。 The result is a cleaner, more controlled path toward smaller
Researchers discovered that hydrogen radicals generated by intense UV light can break down stubborn PFAS “forever chemicals” without added chemicals。 The breakthrough reveals a key mechanism that could lead to greener and more effective technologies for permanently destroying these pollutants
Researchers have created a new way to reconstruct the evolutionary history of complex plant genomes by analyzing genetic traces left by transposable elements。 The technique revealed that modern strawberries were assembled through multiple ancient genome-merging events, shedding new light on how major crop species evolved
Astronomers may be closing in on a long-standing cosmic mystery: why some of the universe’s biggest galaxies seem to have far fewer stars than expected。 Using NASA- and JAXA-supported XRISM observations of a galaxy called NGC 4151, researchers found strong evidence that supermassive black holes can unleash powerful winds that blow away the raw mate
A new study from Northern Arizona University is raising red flags about a widely used global emissions database from Climate TRACE, a consortium co-founded by Al Gore。 Researchers found that the database may be dramatically undercounting carbon dioxide emissions from cars and trucks in cities—by an average of 70% across 260 U。 cities, with some cit
A new catalyst design could significantly improve the conversion of CO2 into methanol, an important fuel and chemical feedstock。 Researchers separated key reaction steps across different catalyst sites, avoiding a long-standing trade-off between speed and efficiency。 The result was about three times more methanol production than standard commercial
