“Survival of the fittest” has popularly described evolution for more than a century, but a new study published in the Royal Society journal Biology Letters provides further evidence that random…

An Earth-like planet is likely forming 424 light-years away in a star system called HD 113766, say astronomers using NASA's Spitzer Space Telescope. Scientists have discovered a huge belt of warm…

The newest dinosaur species to emerge from Grand Staircase-Escalante National Monument had some serious bite, according to researchers from the Utah Museum of Natural History (UNMH) at the University…

The ozone hole over Antarctica has shrunk 30 percent as compared to last year's record size. According to measurements, this year’s ozone loss peaked at 27.7 million tons, compared to the 2006 record…

Researchers at UCLA have developed a model that could help engineers and scientists speed up the development of hydrogen-fueled vehicles by identifying promising hydrogen-storage materials and…

Einstein's Theory Of General Relativity has been under assault for the better part of a century. No one can really prove it wrong but it's commonly assumed to be wrong. Sergei Kopeikin, associate…

Neural prosthetic devices represent an engineer's approach to treating paralysis and amputation. Electronics are used to monitor the neural signals that reflect an individual's intentions for the…

With atoms and molecules in a gas moving at thousands of kilometres per hour, physicists have long sought a way to slow them down to a few kilometres per hour to trap them. A group of physicists from…

Scientists at the University of Missouri-St. Louis used DNA sequences from feather lice to study how island populations of their host, the Galápagos Hawk might have colonized the Galápagos islands,…

New York City’s infant mortality rate – widely regarded as a barometer of a population’s general health – fell slightly in 2006, the Health Department reported today. The rate in 2006 was 5.9 infant…

If one spouse exercises, quits smoking, stops drinking alcohol, receives a flu shot, or undergoes a cholesterol screening, the other spouse is more likely to do the same, according to a new study in…

Dark matter is believed to exist in the form of tiny particles that do not interact with light. Because they don’t emit or reflect electromagnetic radiation the way atomic, or baryonic, matter does,…

Discovered by Sir John Herschel in 1834, NGC 3603 is known to harbour a blue supergiant star called Sher 25, believed to be on the verge of exploding as a supernova. It is often known as the Milky…

Lower muscle mass and an increase in body fat are common consequences of growing older. While exercise is a proven way to prevent the loss of muscle mass, a new study led by McMaster researcher Dr.…

We all know about the advanced machines of the ancient Greeks, like the water pumps and the steam engines devised by their greatest minds, but what is less known is how those with little theoretical…

If space travelers ever visit Saturn's largest moon, they will find a tropical world where temperatures plunge to minus 274 degrees Fahrenheit, methane rains from the sky and dunes of ice or tar…

Scientists have made an important advance in understanding the genetic processes that give flowers, leaves and plants their bright colours. The knowledge could lead to a range of benefits, including…

The gender ratio in math science and engineering is approximately 3 men to every 1 woman, say Stanford psychologists Mary Murphy and Claude Steele, and situational cues, like being outnumbered, may…

C02 Storage is an intriguing idea but there are many questions that need to be resolved before it can be realistically implemented. CO2GeoNet, the European Network of Excellence on geological…

The first significant genetic finding in premenstrual dysphoric disorder (PMDD) has now been reported. PMDD is a very severe form of the more commonly known premenstrual syndrome, or PMS. PMDD is…
