Larger than London or Paris in its time, what is now America’s heartland had a magnificent city between 1030 and 1200 CE. Now known as Cahokia, the city occupied the wide floodplain where the Missouri and Mississippi Rivers meet, near present-day St. Louis.
A longtime anthropology professor who studies violence among prehistoric people in California has published his work, outlining that there are two views related to the origins of violence and warfare in humans. One view suggests that humans in earlier times were peaceful and lived in harmony, and a second view that there has always been competition for resources, war and violence.
The skeletons of two men who were buried apparently hand in hand during an outbreak of the Black Death have been excavated from a plague burial ground in London.
The men, believed to have been in their 40s, were buried in the early 15th century in a carefully dug double grave, in identical positions, with heads turned towards the right and the left hand of one man apparently clasping the right hand of the other.
In a 16-year period during which changes in state marriage laws were sweeping the nation, states that adopted laws allowing same-sex marriage saw an immediate decline in suicide attempts by gay, lesbian and bisexual high school students — a group in which attempted suicide is two to seven times more common than among their heterosexual peers.
There’s a multi-billion-dollar industry devoted to products that fight signs of aging, but moisturizers only go skin deep. Aging occurs deeper — at a cellular level — and scientists have found that eating less can slow this cellular process.
Taxing junk food and subsidising healthier options could save Australia billions of dollars by preventing people from getting sick. A study that looked at consumer habits finds that the two-pronged approach should be more effective than one based on taxes alone.

The amount of effort required to do something influences what we think we see, finds a new study, suggesting we’re biased towards perceiving anything challenging to be less appealing.
Science is demonstrating what we intuitively know: Nature makes us happy.
When we first see Elizabeth Bennett, in the 2005 film of Pride and Prejudice, she is walking through a field, surrounded by birdsong and trees. Nature, for Jane Austen’s heroines, is always a source of solace and inspiration. And as Florence Williams shows in her new book, The Nature Fix: Why Nature Makes Us Happier, Healthier, and More Creative, modern technology is now revealing what goes on in our brains when we step outdoors—and why nature is so good for us.
It may seem like a doomed attempt to mix business and pleasure. But a growing number of young professionals in Silicon Valley insist that taking small doses of psychedelic drugs simply makes them perform better at work – becoming more creative and focused. The practice, known as “microdosing”, involves taking minute quantities of drugs such as LSD, psilocybin (magic mushrooms) or mescaline (found in the Peyote cactus) every few days.
Seemingly countless self-help books and seminars tell you to tap into the right side of your brain to stimulate creativity. But forget the “right-brain” myth — a new study suggests it’s how well the two brain hemispheres communicate that sets highly creative people apart.
For the first time since the Viking missions to Mars in the 1970s, NASA is making the search for evidence of life on another world the primary science goal of a space mission. The target world is Jupiter’s moon Europa, considered possibly habitable because of its subsurface ocean.
The ExoMars Trace Gas Orbiter (TGO) is about to go surfing — at the Red Planet.
Through 13 months of delicate maneuvers, the spacecraft will carefully skim above Mars’ atmosphere to refine its orbit. Once that’s finished in 2018, TGO will be all set to do science at Mars — and also ready to communicate with robots on the surface, such as the upcoming ExoMars rover.
Despite humanity’s reliance on the sun to survive, not much is known about the blazing star at the center of the universe. In fact, it’s one of the least understood objects in the solar system. NASA announced a plan to change that, not just to better understand the sun, but to prevent possibly deadly threats from solar weather.
Over the past decades, scientists have wrestled with a problem involving the Big Bang Theory. The Big Bang Theory suggests that there should be three times as much lithium as we can observe. Why is there such a discrepancy between prediction and observation?
To get into that problem, let’s back up a bit.
NASA’s Spitzer Space Telescope has revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, the area around the parent star where a rocky planet is most likely to have liquid water.
In a few million years, Mars’s moon Phobos will be shredded into pieces that will settle into a flat ring like Saturn’s. But bits of Mars’s two moons may already be circling the Red Planet, some of it in the form of nascent rings.
Astronomers have long thought it was possible for Mars to be encircled by rings made of bits of rock kicked up from its moons Phobos and Deimos, but no one had ever observed them.
Researcher Dr. Mary Bourke from Trinity College Dublin have discovered a patch of land in an ancient valley in Mars’ Lucaya Crater that appears to have held water in the not-too-distant past, making it a prime target to search for past life forms on the Red Planet. Signs of water past and present pop up everywhere on Mars from now-dry, wriggly riverbeds snaking across arid plains to water ice exposed at the poles during the Martian summer.
