What a locust can teach us about how neuromodulators alter odor processing

When you walk into a bakery and smell fresh cookies, the enticing smell draws you in. After you eat a handful of cookies, though, the same smell likely doesn't send you back for more. Researchers in the McKelvey School of Engineering at Washington University in St. Louis sought t

Rare insect discovery reveals a new species from the dinosaur age

Some 99 million years ago, during the age of the dinosaurs, a tiny insect belonging to a species previously unknown to science became trapped in tree resin. The resin hardened and turned into amber, and the fossil preserved within it has now enabled a team of researchers from the

Atomic motion could help push solar cells beyond conventional limits

The bulk photovoltaic effect (BPVE), a photoelectric effect that generates photocurrent without a p–n junction, can persist even when a material's average crystal structure remains centrosymmetric, a study from Institute of Science Tokyo has found. Researchers demonstrated this i

Quantum systems never quite forget where they came from

Even the most chaotic quantum systems keep a permanent mark of their own past—a "quantum birthmark"—that never fades. Researchers from Tampere University, Harvard University and TU Dresden discovered the feature in their recent study. Their findings shed new light on the elusive

A novel path to fusion ignition: Heat first, then add fuel

For more than 70 years, fusion energy researchers have used a particular equation to judge whether a plasma would stay hot and dense enough—for long enough—to reach a point where it could sustain itself without any more external power added. While that equation marks the finish l

All the drama around AI’s takeover of mathematics

This past year, OpenAI, Anthropic, and other labs have announced breakthroughs on numerous long-standing mathematical problems, in some cases pushing well beyond what researchers expected current systems to be capable of — including resolving one of the famous Millennium Prize pr

Scientists discover a human brain gene that can jump through DNA

Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a mobile piece of DNA known as a trans

Cancer-fighting t cells burn out. Scientists may have found a fix

Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn thro

The “glue” holding your cells together has a surprising second job

Scientists have discovered that E-cadherin, a protein best known as the “glue” holding cells and tissues together, has a surprising second job: helping epithelial cells swallow nearby dead cells. Using live zebrafish and mouse embryos, researchers found that cells can dramaticall

Could quitting ultra-processed food boost your mental health?

People with depression who dramatically cut ultra-processed foods experienced notable improvements in their symptoms in a small preliminary study. Researchers suspect healthier eating may benefit the brain partly by reducing gut damage and chronic inflammation.
