Until fairly recently, many scientists thought that only humans had culture, but that idea is now being crushed by an avalanche of recent research with animals. Two new studies in monkeys and whales take the work further, showing how new cultural traditions can be formed and how conformity might help a species survive and prosper. The findings may also help researchers distinguish the differences between animal and human cultures.

Humans lived in South America at the height of the last ice age, thousands of years earlier than we thought, according to a controversial study. A team claims to have found 22,000-year-old stone tools at a site in Brazil, though other archaeologists are disputing the claim.

Christelle Lahaye of Michel de Montaigne Bordeaux 3 University in France and colleagues excavated a rock shelter in north-east Brazil and found 113 stone tools.

Carbon dioxide concentrations in the Earth's atmosphere are on the cusp of reaching 400 parts per million for the first time in 3 million years.

The daily CO2 level, measured at the Mauna Loa Observatory in Hawaii, was 399.72 parts per million last Thursday, and a few hourly readings had risen to more than 400 parts per million.

As potentially game-changing as the steam engine or telegraph were in their day, 3D printing could herald a new industrial revolution, experts say.

For the uninitiated, the prospect of printers turning out any object you want at the click of a button may seem like the stuff of science fiction.

But 3D printing is already here, is developing fast, and looks set to leap from the labs and niche industries onto the wider market.

A site near Stonehenge has revealed archaeological evidence that hunters lived just a mile from Stonehenge roughly 5,000 years prior to the construction of the first stones, new research suggests.

What's more, the site, which was occupied continuously for 3,000 years, had evidence of burning, thousands of flint tool fragments and bones of wild aurochs, a type of extinct giant cow. That suggests the area near Stonehenge may have been an auroch migration route that became an ancient feasting site, drawing people together from across different cultures in the region, wrote lead researcher David Jacques of the Open University in the United Kingdeom, in an email.

The speed of light is constant, or so textbooks say. But some scientists are exploring the possibility that this cosmic speed limit changes, a consequence of the nature of the vacuum of space.

The definition of the speed of light has some broader implications for fields such as cosmology and astronomy, which assume a stable velocity for light over time. For instance, the speed of light comes up when measuring the fine structure constant (alpha), which defines the strength of the electromagnetic force. And a varying light speed would change the strengths of molecular bonds and the density of nuclear matter itself.

All bets are off. A prominent physicist has just announced that he's developed a proof for "time crystals" that can move thanks to a break in the symmetry of time. And now he's about to test his proof in the real world.

A lost ancient Egyptian city submerged beneath the sea 1,200 years ago is starting to reveal what life was like in the legendary port of Thonis-Heracleion.

For centuries it was thought to be a legend, a city of extraordinary wealth mentioned in Homer, visited by Helen of Troy and Paris, her lover, but apparently buried under the sea.

In fact, Heracleion was true, and a decade after divers began uncovering its treasures, archaeologists have produced a picture of what life was like in the city in the era of the pharaohs.

Sea surface temperatures in the Northeast Shelf Large Marine Ecosystem during 2012 were the highest recorded in 150 years, according to the latest Ecosystem Advisory issued by NOAA's Northeast Fisheries Science Center (NEFSC). These high sea surface temperatures (SSTs) are the latest in a trend of above average temperature seen during the spring and summer seasons, and part of a pattern of elevated temperatures occurring in the Northwest Atlantic, but not seen elsewhere in the ocean basin over the past century.

While everyone is familiar with water in the liquid, ice, and gas phases, water can also exist in many other phases over a vast range of temperature and pressure conditions. One lesser known phase of water is the superionic phase, which is considered an "ice" but exists somewhere between a solid and a liquid: while the oxygen atoms occupy fixed lattice positions as in a solid, the hydrogen atoms migrate through the lattice as in a fluid. Until now, scientists have thought that there was only one phase of superionic ice, but scientists in a new study have discovered a second phase that is more stable than the original. The new phase of superionic ice could make up a large component of the interiors of giant icy planets such as Uranus and Neptune.

Researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University have designed a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid.

"For solar and wind power to be used in a significant way, we need a battery made of economical materials that are easy to scale and still efficient."
