For people with epilepsy, sleeping after a seizure can cause more seizures
Sleep may encode seizures in the brain by recycling memory consolidation processes, potentially making them harder to treat and prevent, a new study suggests. But new research also suggests possible ways to counter its effects. It uses electrical stimulation to prevent the brain from “remembering” the seizure, the researchers say. “This opens up a whole […]
California wildfire season is changing, with an increase in fires following traditional high-risk periods, study finds
Climate change is shifting wildfire seasons in North America, but the direction of those changes depends on local ecosystems, a new study shows. On average, fire seasons are moving forward in the northern boreal forests of Alaska and Canada. Almost no changes can be seen in the grassland area. And the dry West and California’s […]
The world’s smallest QR code can store thousands of years of data, but you’ll need an electron microscope to see it
Scientists have created the world’s smallest QR code, measuring just 3.07 × 10⁻⁹ square inches (1.98 square micrometers). The data can be stored for thousands of years and is so small that you need an electron microscope to see it. Each pixel in a QR code is just 49 nanometers in diameter, even smaller than […]

Creating a ‘digital twin’ of yourself could revolutionize future surgeries and make medical procedures more personal
Dr. John Pandolfino jokes that he comes from a generational family of electricians and plumbers, and continues to follow the family business as a gastroenterologist. That’s because the esophagus, the organ that transports food from the mouth to the stomach, is essentially a pipe with electrical wiring attached to it, he said. Mr. Pandolfino is […]
Replacing humans with machines leaves truckloads of food stranded and unusable
Supermarket shelves can appear full, despite the strain on the food system beneath them. The fruits are neatly stacked, and the cooled meat is placed in its place. The supply chain appears to be working well. But looks can be deceiving. Today, food moves through the supply chain as it is recognized by databases, platforms […]
‘Exposed Skull’ reveals its dark secret in new images from the James Webb Telescope: Space Photo of the Week
simple facts What it is: Nebula PMR 1, also known as “Exposed Cranium” Location: 5,000 light years away, in the constellation Vela Share date: February 25, 2026. The powerful James Webb Space Telescope (JWST) has revealed never-before-seen details of a cosmic “skull” made of the glowing remains of a dying star. This brain object, named […]
Why aren’t mammals as colorful as reptiles, birds, and fish?
Lizards, birds, and fish often have bright colors ranging from neon pink to deep purple, while most mammals are quite dull. So why don’t mammals match the bright colors of other animals? Many factors ultimately lead to the browns, blacks, and whites that make up the fur of most mammals. The first is color expression. […]
Huge 3D map of the universe shows a glowing ‘ocean of light’ near cosmic dawn
Astronomers have created one of the most accurate and comprehensive maps of the universe ever created, revealing a glorious “ocean of light” that permeated the early universe. Unlike other universal maps, this 3D representation consists of light emitted by a single element. Hydrogen is the simplest and most abundant element in the universe, and when […]
‘It could completely revolutionize the treatment of depression’: Researchers explore promising immunotherapy to treat psychiatric symptoms
I was really surprised. When psychiatrist Dr. James Murrow teamed up with dermatologist Dr. Emma Gutman-Yaskey to investigate how the immune system contributes to depression, he didn’t expect to find a promising treatment. In a study published in February in the journal Molecular Psychiatry, Murrow, Guttmann-Yassky and colleagues uncovered similarities in the immune systems of […]
