Chip design dramatically reduces energy needed to compute with light
MIT researchers have developed a novel "photonic" chip that uses light instead of electricity—and consumes relatively little power in the process. The chip could...
Most-detailed-ever simulations of black hole solve longstanding mystery
An international team has constructed the most detailed, highest resolution simulation of a black hole to date. The simulation proves theoretical predictions about the...
Is there a limit to human endurance? Science says yes
From the Ironman triathlon to the Tour de France, some competitions test the limits of even the toughest endurance athletes. Now, a new study...
Citizen scientists design brand new proteins
A team of researchers encoded their specialized knowledge into the computer game Foldit to enable citizen scientists to successfully design synthetic proteins for the...
DNA from 31,000-year-old milk teeth leads to discovery of new group of ancient Siberians
Two children's milk teeth buried deep in a remote archaeological site in north eastern Siberia have revealed a previously unknown group of people lived...
Ancient DNA sheds light on Arctic hunter-gatherer migration to North America 5,000 years ago
The first humans in North America arrived from Asia some time before 14,500 years ago. The next major stream of gene flow came about...
Scientists create plasma using nanowires and long-wavelength, ultrashort-pulse laser
The three classic physical states—solid, liquid and gaseous—can be observed in any normal kitchen, for example when you bring an ice cube to the...
Metal foam stops .50 caliber rounds as well as steel – at less than...
Researchers have demonstrated that vehicle armor using composite metal foam (CMF) can stop ball and armor-piercing .50 caliber rounds as well as conventional steel...
Food freshness sensors could replace ‘use-by’ dates to cut food waste
The researchers say the new sensors could help detect spoilage and reduce food waste for supermarkets and consumers.
One in three UK consumers throw away...
Bees can link symbols to numbers, study finds
We've learned bees can understand zero and do basic math, and now a new study shows their tiny insect brains may be capable of...
Feathers came first, then birds
New research, led by the University of Bristol, suggests that feathers arose 100 million years before birds—changing how we look at dinosaurs, birds, and...
