Researchers used special cameras that can see many wavelengths of light to study how different drinks leave marks on surfaces. They set up a fake crime scene and collected images of nine types of beverage stains: papaya, coffee, pomegranate, orange, tea, wine, whisky, rum, and brandy. The camera cap
Researchers recently found a bright purple-and-orange moth hidden in Crete’s White Mountains, and they gave it an unusual name: the Pope Leo moth. The new species wasn’t just another discovery—it was hiding in plain sight. For years, scientists had been calling it by another name, Pyralis kachetical
Public universities were built to lift people up, not shut them out. But today, many wonder if these schools still serve the public good. Rising costs make families hesitate before signing up. Some question whether degrees still lead to good jobs. Others doubt if universities are spending money wise
Researchers watched AI agents turn into troublemakers in a virtual test world. Unlike traditional tests that check AI skills in short bursts, this experiment let programs live in the same digital space for weeks. They could vote, build relationships, and even run small economies—just like a tiny soc
Researchers dug into two big databases in Brazil to track how often boys and men report being sexually abused. One system keeps health records, while the other logs public security incidents. When they compared numbers from 2010 to 2022, they found something surprising. Rape and forced sex reports
Research shows that hitting about 8, 500 daily steps can help people hold onto weight loss for months. A fresh review of 18 studies with nearly 4, 000 adults found those averaging 8, 500 steps a day kept off about 3. 3% of their lost weight after ten months. Each extra thousand steps added more prot
Using virtual reality for shopping is becoming a big trend. Stores and designers love the idea of creating lifelike spaces online, but pushing for super realistic scenes might actually make things harder for shoppers.

Researchers tracked fatal police shootings from 2015 to 2022 across more than 3, 000 U. S. counties. They found that out of every 10, 000 people, Black residents were 15 times more likely to be shot and killed by police than White residents. Hispanic residents faced about 2. 5 times higher risk than
Researchers turned to a classic game to teach AI how to make smarter choices in scientific work. The game was Battleship, where players guess ship positions on a hidden grid. Instead of just playing for fun, AI used the game to practice managing limited resources—just like scientists do when running
Researchers have taken a new look at a 17th‑century book about magnetism that first appeared in 1600. They didn’t just count how many copies survived; they also read the notes people wrote inside those books. By combining these two kinds of data, the team could see where readers stopped, highlighted
