Two-color glowing molecule could make wind tunnel tests more accurate

Most sensors can measure only one thing at a time, like a thermometer for temperature or a pressure gauge for pressure. Measuring two properties accurately from the same surface at the same moment usually means using two separate instruments—adding cost and complexity to the proc

Exposed ends and bends attract DNA-cutting enzymes, live imaging reveals

Researchers at the Nano Life Science Institute (WPI-NanoLSI) at Kanazawa University have directly visualized how enzymes find and break DNA molecules in real time. Using high-speed atomic force microscopy, the team followed individual enzymes as they moved along DNA and found tha

Ancient spearheads reveal how Ice Age humans learned the land

At the end of the last ice age, early humans crisscrossed the Americas following seasons, rivers and game, often with a trusty spear in hand. Nearly 13,000 years later, archaeologists are using those spearheads to study how America's first inhabitants understood risk.

Blood tests reveal why astronauts get constipated in space

Spaceflight may dramatically change the gut within weeks, causing bacteria to break down more protein as food moves more slowly through the intestines. The shift could help explain astronaut constipation and may have wider effects on health, making it an important concern for fut

Quantum computer simulates matter “popping into existence”

Scientists recreated a particle-forming process linked to the extreme physics of the early universe using a 13-ion quantum simulator. The breakthrough suggests quantum computers could eventually help researchers investigate how matter formed and evolved after the Big Bang.
