Scientists have shown that anger, anxiety, and depression not only affect the functioning of the heart, but also increase the risk for heart disease. Stroke and heart attacks are the end products of progressive damage to blood vessels supplying the heart and brain, a process called atherosclerosis. Atherosclerosis progresses when there are high levels of chemicals in the body called pro-inflammatory cytokines...

Cabin crew had to intervene after the woman, said to be in her 20s and flying with her parents, disappeared into the toilets with a man sitting next to her...

Mr. Jobs’s conduct is a reminder that the difference between genius and potentially criminal behavior can be a fine line.

Sometime in the late Pleistocene period, humans and Neanderthals are believed to have lived together. Only one species still exists, and people who study human pre-history have battled for decades over the reasons why. One of the more popular theories is that modern humans migrating out of Africa killed off the Neanderthal, because the humans were...

A technical problem with optical character recognition software creates some awkward moments in romantic novels

Regardless of whether or not you like the original trilogy, you'll probably get a kick out of this Honest Trailers video.

Go back to the 1990's via this nostalgic TV simulator and relive the original ads, music videos, movie trailers, shows and more!

The deadly avalanche on Everest earlier this month wasn't technically an avalanche. It was an "ice release"—a collapse of a glacial mass known as a serac. Rather than getting swept up by a rush of powdery snow across a slope, the victims fell under the blunt force of house-sized ice blocks tumbling through the Khumbu Icefall, an unavoidable obstacle on the most popular route up Everest. The worst accident in the mountain's history has effectively ended the 2014 climbing season.

The Great Plains of the United States produce the most beautiful thunderstorms, supercells, and unique cloud structures in the world. I spent the summer of 2013 on the northern Great Plains photographing some of these storms. Shot in Wyoming and South Dakota.

The return of tornado season with a vengeance has people asking again about a possible link to climate change. At the same time, tantalizing new preliminary research finds “some evidence to suggest that tornadoes are, in fact, getting stronger.

Irish Nachos are a fun twist on traditional nachos, made with potatoes and bacon.

Sperner’s lemma can help us find a fully labeled triangle, but how does that divide rent? Building on the work of two other mathematicians, Forest Simmons and Michael Starbird, Dr. Su realized that the small, fully labeled triangle could represent the rooms and prices in a hypothetical apartment. Based on people’s decisions to label the triangles at each interior corner, an algorithm could be used to follow a winding path through an infinite field...

Scientists have developed faster, more energy-efficient microchips based on the human brain -- 9,000 times faster and using significantly less power than a typical PC. This offers greater possibilities for advances in robotics and a new way of understanding the brain. For instance, a chip as fast and efficient as the human brain could drive prosthetic limbs with the speed and complexity of our own actions.

This is the first map of its kind on such a scale and level of complexity, depicts our planet as it would look without its polar ice caps, with sea levels 260 ft higher as they are today.

A woman's body is found in London. DNA turns up a hit, yet the suspect apparently died weeks before the alleged victim. Here, forensic scientist Dr Mike Silverman tells the story of one of the strangest cases of his career.

A newly identified vulnerable site on HIV, only the fifth discovered to date, has been reported by a team led by scientists at The Scripps Research Institute in La Jolla. The research contains a series of insights that marks a significant advance in the long and so far futile quest for a vaccine to prevent HIV infection.

Police departments in New York City may soon be using geo-tagged tweets to predict crime. It sounds like a far-fetched sci-fi scenario a la Minority Report, but when I contacted Dr. Matthew Greber, the University of Virginia researcher behind the technology, he explained that the system is far more mathematical than metaphysical.

Facial recognition technology isn’t yet sophisticated enough to identify people accurately — something which most technology watchers cite as a reason not to be overly concerned, yet, about its privacy implications.

Almost half of all jobs could be automated by computers within two decades and "no government is prepared" for the tsunami of social change that will follow, according to the Economist. The magazine's 2014 analysis of the impact of technology paints a pretty bleak picture of the future.

The most futuristic medical treatment ever imagined is now a reality.

They can recognize change in social order outside their communities.

Coyote in action There's a very interesting "bonus" clip inside.

The Silk Road, for all its clever uses of security protections like Tor and Bitcoin to protect the site's lucrative drug trade, still offered its enemies a single point of failure. When the FBI seized the server that hosted the market, the billion-dollar drug bazaar came crashing down. If one group of Bitcoin black market enthusiasts has their way, the next online free-trade zone could be a much more elusive target.

Many people with profound hearing loss have been helped by devices called cochlear implants, but their hearing is still far from normal. They often have trouble distinguishing different musical pitches, for example, or hearing a conversation in a noisy room. Now, researchers have found a clever way of using cochlear implants to deliver new genes into the ear—a therapy that, in guinea pigs, dramatically improves hearing.

When a baby cries at night, exhausted parents scramble to figure out why. He’s hungry. Wet. Cold. Lonely. But now, a Harvard scientist offers more sinister explanation: The baby who demands to be breastfed in the middle of the night is preventing his mom from getting pregnant again.

Engineers from the Korean Advanced Institute of Science and Technology (KAIST) have developed a system that can power devices up to five metres away.

Hitachi has said it will install a lift capable of reaching speeds of 72km/h (45mph) into a skyscraper in Guangzhou, southern China.

A technique called chemical vapor deposition can produce diamonds, created from gases, that are virtually indistinguishable from mined diamonds. Credit

These two beautiful giraffes can be found in Ranthambhore in India.

Knocking down a concrete building usually takes brute force: Wrecking balls, huge excavators, or explosives rip apart walls while fire hoses spray water to keep the clouds of dust down. It’s an energy-intensive process, and after everything’s been torn apart, the concrete often ends up in a landfill or has to be trucked to a recycling facility. But a new concrete-erasing robot may eventually transform the messy business of demolition.
