How the Hashtag Became the Way to Instantly Invite Literally Everyone Into the Conversation

In the nascent days of Twitter, users wanted a quick way to cluster posts about a single subject. Someone suggested using a pound sign, and #TheRestIsHistory

A team of researchers put out information about a fake disease, and A.I.-powered chatbots fell for it.

Scientists Invented a Disease to Test Whether A.I. Knew It Was Fake. Then, Chatbots Started Saying It Was Real

The eye condition bixonimania doesn’t exist, but neither bots nor some researchers caught that the content was fabricated—despite obvious clues

Google Wants to Release 32 Million Mosquitoes in California and Florida. Here’s Why

The company is asking the U.S. Environmental Protection Agency for permission to release millions of sterilized mosquitoes in order to fight their disease-spreading counterparts

For 80 years, most mathematicians assumed Paul Erdős' strategy was correct.

Mathematicians Puzzled Over a Famous Problem for 80 Years. Now, They’ve Used A.I. to Identify a Clever Solution

In 1946, the mathematician Paul Erdős posed the unit distance problem—and suggested a winning strategy. An A.I. model has now landed on a better one. Why didn’t humans get there first?

Scientists carried out their experiments in the bacterium Escherichia coli. Cells of the species are artificially colored blue in this microscope image.

Scientists Used A.I. to Redesign a Microbe’s Machinery to Function Without a Key Ingredient of Life

Although the researchers did not create an entire cell that could function without a crucial building block, the findings represent a big step in synthetic biology and provide a glimpse at how Earth’s earliest organisms may have lived

Visitors view the Star-Spangled Banner at the National Museum of American History.

The National Museum of American History Is Displaying 250 Objects to Commemorate the Country’s Big Birthday. Here’s the Story Behind Ten of the Artifacts

Featuring iconic and everyday items, including a Revolutionary War gunboat and a first-generation iPod, “In Pursuit of Life, Liberty & Happiness” is open now at the museum

Scientists used acidic and basic solutions to trigger chemical reactions in algae.

These Marine Algae Glow When Waves Disturb Them. Their Bioluminescence Could Power Electricity-Free Lamps of the Future

The single-celled organisms usually shimmer for mere milliseconds, but researchers figured out how to sustain their illumination. The technology could one day be used to light robots’ ways in the deep sea or space

Hammarby Sjöstad was originally engineered to have a carbon footprint 50 percent lower than the rest of Stockholm.

This Stockholm Neighborhood Was Built on Ambitious Sustainability Goals. When It Came Up Short, It Doubled Down and Became a Blueprint for Others

The original plan for Hammarby Sjöstad was for an eco-village aimed at attracting the Olympics. They never came, but the locals moved in and, with upgrades, hope to be carbon neutral by 2030

This Island in Scotland Is Actually a Man-Made Mini Landmass Resting on a Wooden Platform, New Discovery Shows

Scientists made significant advances in underwater archaeology techniques and photogrammetry while investigating the crannog site

The A.I. model outperformed two doctors when presented with data from dozens of real E.R. patients.

A.I. Outperformed Doctors at Diagnosing Real-World E.R. Patients in a New Study. That Doesn’t Mean Computers Will Replace Clinicians

One of OpenAI’s large language models did better than physicians in several experiments, hinting that A.I.-assisted emergency medical care could be around the corner

The man in his 30s was found just outside Pompeii's gates.

New Research

This Man Fled Pompeii as Mount Vesuvius Erupted. Archaeologists Found Him 2,000 Years Later, Holding a Bowl to Protect His Head and a Lamp to Light His Way

Recent excavations revealed two skeletons just outside the ancient city’s walls. Researchers also created an A.I.-generated reconstruction of one of the victim’s harrowing final moments

Two Athletes Smashed a Marathon Milestone, Running 26.2 Miles in Under Two Hours. Here’s the Science Behind Their Achievements

An intense training regimen, good weather conditions, physiology and lightweight shoes probably played a role in their astounding performances during the London Marathon on Sunday

The astrolabe weighs more than 18 pounds.

This Giant 400-Year-Old Astrolabe—Made by Mughal Master Craftsmen and Owned by Royalty—Fetched Millions at Auction

Ancient Greek astronomers and early Islamic scientists used astrolabes as mechanical computers to calculate time, determine height and navigate by the stars

More than 50 million people suffer from epilepsy around the world, making it one of the most common and severe neurological disorders globally.

These Young Innovators Have Created a ‘Fitbit’ to Predict Epileptic Seizures

Truman Pierson and Christopher Fitz are developing behind-the-ear EEG patches and an accompanying app that issues an alert if the user is at high risk for a seizure in the next hour
