Why do some young men turn to crime, while others don't? An international study shows that preferences such as risk tolerance, impatience and altruism as well as self-control can predict who will commit crime. Risk-tolerant, impatient young men are more likely to commit property crime, while people with low self-control tend to commit violent, drug and sexual offenses.

A new study involving more than 100 scientists from across the globe and the largest forest database yet assembled estimates that there are about 73,000 tree species on Earth, including about 9,200 species yet to be discovered.

A new study by a team of researchers from Israel and Ghana has brought the first evidence of nonrandom mutation in human genes, challenging a core assumption at the heart of evolutionary theory by showing a long-term directional mutational response to environmental pressure. Using a novel method, researchers led by Professor Adi Livnat from the University of Haifa showed that the rate of generation of the HbS mutation, which protects against malaria, is higher in people from Africa, where malaria is endemic...

Rice University scientists are using machine-learning techniques to streamline the process of synthesizing graphene from waste through flash Joule heating.

New research suggests that ancient trees possess far more than an awe-inspiring presence and a suite of ecological services to forests—they also sustain the entire population of trees' ability to adapt to a rapidly changing environment.

Two researchers from the University of Ottawa are the first to map out all the glaciers that end in the ocean in the Northern Hemisphere and provide a measure of their rate of change over the last 20 years. Their findings will help better understand—and perhaps predict—the impact of climate change north of the equator.

The carbon material graphene has no well-defined thickness; it merely consists of one single layer of atoms. It is therefore often referred to as a "two-dimensional material." Trying to make a three-dimensional structure out of it may sound contradictory at first, but it is an important goal: if the properties of the graphene layer are to be exploited best, then as much active surface area as possible must be integrated within a limited volume.

A team of researchers working at the Alfred Wegener Institute Helmholtz Centre for Polar and Marine Research has found via models, that due to a long lag time, the Greenland ice sheet could continue losing ice over the next century whether global warming is brought under control or not. They have posted a paper describing their findings in the open-access journal PLOS ONE.

With the approaching snowstorm predicted to dust the Baltimore area and blanket the Eastern Shore while creating dangerous conditions into Saturday morning, state highway crews and local transportation departments spent Friday preparing the roads.

The carbon stock in managed boreal forest landscapes is increasing, while it is relatively unchanged in less intensively utilized forests where carbon losses due to forest fires have instead been significant during 1990-2017, according to a new report by the International Boreal Forest Research Association (IBFRA).

You might think hibernation is just a nap that bears take during the wintertime, but it's really much more complicated and climate based.

Climate change could result in the financial toll of flooding rising by more than a quarter in the United States by 2050—and disadvantaged communities will bear the biggest brunt, according to new research.

Numerous surveys of forest owners have found that private family forest owners in Finland value nature and biodiversity. However, such findings tell us more about the general ideals of Western culture than about forest owners as protectors of biodiversity.

When a solid object hits a liquid, the impact produces shock waves: a process that has long occupied engineers due to its implications for design of hydraulic systems or motors. KAUST researchers now show that impacts at speeds lower than expected can still induce these damaging shock waves.

When you're looking for a job, any number of factors can work against you. When you're passed over for a job you seek because you're told you're "overqualified" it may be initially flattering, but it's most likely not what you want to hear. But does being labeled as "overqualified" keep you from getting the job? According to new research from the University of California San Diego's Rady School of Management, it may depend on your gender.

Towering Squaw Peak has groomed generations of America's most elite winter Olympians, from racer Tamara McKinney and freestylist Jonny Mosely to six members of this year's Alpine Team U.S..

Sara Bogard halted her dog as the two began descending the cliff down to Manchester Beach, along the Mendocino coast.

As much as modern society worships chocolate, cacao—the plant chocolate comes from—it was believed to be even more divine to ancient Mayas. The Maya considered cacao beans to be a gift from the gods and even used them as currency because of their value.

Human children are known for their sensitivity to social cues (such as eye-gaze and joint attention) more so than other primates. While most research on joint attention (two people focused on the same object) has focused on children living in Western and North American countries, little is known about how caregiver-child interactions differ across cultural groups beyond infancy. To fill this gap, a new study by researchers at the University of Wisconsin-Green Bay and Waseda University examined caregiver-child... Читать дальше...

The Labrador Sea between Canada and Greenland is often referred to as a 'lung of the deep ocean' because it is one of only a handful of locations worldwide where oxygen from the atmosphere can enter the deepest layers of the ocean. The ability to sustain animal life in the deep ocean depends directly on this localized 'deep breathing." This process is driven by wintertime cooling at the sea surface, which makes oxygen-rich, near-surface waters denser and heavy enough to sink to depths of around 2 km in winter.

On September 22, 2020, China announced its climate goal to peak carbon emissions before 2030 and reach carbon neutrality before 2060, which is called the Double Carbon Goal, or Shuang Tan, in Chinese.

Women in sexual relationships with men may change their own sexual behavior in an effort to protect their partners' perceived manhood, a new study finds. The more women perceived their partner's sense of masculinity as fragile, the more they reported faking orgasms and the lower their sexual satisfaction, according to a new study published in Social Psychological and Personality Science.

Electrolysis of water or "water electrosplitting" has received a great deal of attention recently owing to its potential as a clean source of hydrogen, the oft-touted fuel of the future. However, two issues have long stood in the way: the large amount of energy lost, and the cost of electrocatalysts (catalysts used for electrolysis). Fortunately, several new kinds of electrocatalysts have made their appearance, which could potentially solve these issues.

Deploying a technique that promises to supercharge the development of biofuels, researchers at Princeton University have found a way to make yeast cultures glow when producing next generation fuels that could power cars and airplanes.

Photocatalytic overall water splitting (OWS) to produce hydrogen is one of the most promising technologies to solve energy and environmental problems and realize effective conversion and storage of solar energy.
