Sleep deprivation makes for dangerous drivers

Drivers receive plenty of warning against getting behind the wheel while tired, but a recent study shows just how detrimental lack of sleep can be to traffic safety. Drivers who get less than four hours of sleep per night are 11.5 times more likely to crash than those who sleep for the recommended duration of […]

Syrian community the first to domesticate cereals – 11,000 years ago

Oldest evidence for domestication of three types of cereal – barley, spelt and farrow – was recently found at an archaeological site in Syria. Researhers say Neolithic Syrians were the first to gather wild cereals and attempt to domesticate them. They collected wild cereal grains, sowed them in autumn and harvested grain crops in late […]

Feathered dinosaur tail discovered in a piece of amber

Scientific discoveries often come from unexpected places – like a Myanmar amber market, which is where a researcher from Dexu Institute of Palaeontology found an item that offers unique insights into feather evolution in dinosaurs. Browsing through the goods of an amber vendor, researcher Lida Xing found what turned out to be a part of […]

Bird feeders, nests, predators and the complex relationship in bird-human environments

Are bird feeders helpful or harmful for your neighborhood’s birds? Recent study shows that the answer to that question is more complex than a simple “yes” or “no”. The four-year study analyzed connections between songbird nests, bird feeders, and predators in Columbus, Ohio. Results varied: for example, in neighborhoods with large crow populations, bird feeders […]

Seafood consumption 15 times higher in Indigenous communities than national average

For the first time ever, a global analysis has the numbers to demonstrate the importance of seafood to the diet and culture of Indigenous people. Authors estimate that members of coastal Indigenous communities, on average, consume 15 times more seafood per person than non-Indigenous people in the same country. The study collected data from 1900 […]

Exploring the 1430s, the coldest decade of the millennium

Many of the 1430s winters and some springs were extremely cold in several parts of Europe. Researchers analyzed climate archives to reconstruct the climate at the time and figure out its impact on societies. The climate models showed that the harsh conditions were due to natural variations in the climate system, a combination of natural factors […]

‘Lucy’ may have been an avid tree climber, bone analysis suggests

New study gives insight into the lifestyles of early humans – with the help of ‘Lucy’, the famous 3.18 million-year-old Australopithecus afarensis fossil discovered in Africa. Bone analysis of Lucy’s upper arm and upper leg bones reveals that the relative strength of the Australopithecus limbs was between that of humans and chimpanzees. These findings also […]

What it takes to fly: Sparrows’ muscles change to prepare for migration

Evolution might give some birds a much-needed boost for long-distance migrations, a new study suggests. Every year in spring, white-crowned sparrows complete a long journey from their wintering spots to summer breeding grounds. Researchers analyzed a chain of proteins in the sparrows’ muscles during wintering and after the arrival to the late-spring breeding spot. Their […]

A good night’s sleep can make it harder to suppress negative memories

Sleep to forget? Apparently not, when it comes to negatively charged memories you’re actively trying to suppress. New research found that negative associations were easier to recall after a good night’s sleep, even if the individual has been actively trying to suppress those memories. In the study, subjects were given memory suppression tasks which involved […]

Which sports have the most life-saving benefits?

An international research collaboration has found that sports like cycling, swimming, aerobics and racquet offer life-saving benefits. The study examined surveys from over 80,000 adults older than 30 years of age from 1994 to 2008. Results showed that risk of death from cardiovascular disease was reduced in those who participated in cycling, swimming, aerobics and racquet […]

Mystery of astronauts’ blurry vision solved

Nearly two-thirds of astronauts who return from long-term missions on the International Space Station experience blurry vision. The syndrome, known as the visual impairment intracranial pressure, is also responsible for flattening of the eyeball and inflammation of the optic nerve, and can cause permanent far-sightedness. Researchers found the likely cause for this mysterious impairment, which […]

Strongmen of the sea: Coconut crabs have the strongest pinch of all crustaceans

Cracking coconut shells is a great workout routine for the coconut crab, who was recently named as the crustacean with the strongest pinch. A team of researchers measured the pinching force of 28 wild coconut crabs. They found that the bigger the crabs, the harder they pinch, with the maximum force projected to be 3300 […]

Your dog can remember more than you think

Memory in non-human animals is largely a black box, because in humans the biggest proof of memory we have is transmitted through language. But new evidence suggests that dogs may also have memories of moments in a time and a place, known as episodic memories. This was demonstrated through a game where dogs were tested […]

Retreat of the fastest melting glacier in Antarctica began in 1945

The loss of ice on Pine Island Glacier makes up about a quarter of Antarctica’s melt, and a new study pinpointed the source of its fast retreat to the El Nino event of 1945. Using dating techniques, an international team of researchers studied sediment cores from the glacier’s floating ice shelf. They discovered that the […]

A new way to forecast earthquakes with gravity signals

Current early-warning earthquake systems rely on so-called seismic waves, which are produced in the Earth during the rupture. But a new study found another method that could indicate an earthquake even earlier. By analyzing data from the 2011 Tohoku earthquake off the coast of Japan, researchers have identified a prompt gravity signal that precedes seismic […]

International medical community calls for medical neutrality in conflict zones

People wounded in war-torn countries like Syria, Iraq, Afghanistan and South Sudan must have access to medical care, a new BMJ editorial urges. Authors claim that failure to provide medical care to people in war zones is a violation of the International Humanitarian Law as set out in the Geneva Conventions of 1949. They call […]
