  • Shorebird's beak inspires research on water collection
    An engineering professor and his doctoral student have designed a device based on a shorebird's beak that can accumulate water collected from fog and dew. The device could provide water in drought-stricken areas of the world or deserts around the globe.
  • Identifying teen alcohol and drug abuse
    The number of teens who abuse tobacco, alcohol, drugs and other substances hasn?t changed much in the past couple of decades ? but for those who are prone to addiction for one reason or another, the menu of substances to choose from is larger than ever.
  • Reduce traffic congestion: Wirelessly route drivers around congested roadways
    At the Intelligent Transportation Systems World Congress last week, MIT researchers received one of the best-paper awards for a new system, dubbed RoadRunner, that uses GPS-style turn-by-turn directions to route drivers around congested roadways. In simulations using data supplied by Singapore's Lan...
  • Dogs respond to goal-directed behavior at similar level to infants
    Dogs look at a person interacting with a new object longer than a person interacting with a familiar object moved to a different location, suggesting perception of goal-directed behavior, according to a new study.
  • Power isn't enough: Study reveals missing link for effective leadership
    Leaders who fail to take into account their audiences' perspective have a far greater propensity to bungle the issue and conversation, research shows. The researchers found that when power was combined with perspective-taking when making a complex decision, participants were able to discover the opt...
  • Fighting parents hurt children's ability to recognize and regulate emotions
    Exposure to verbal and physical aggression between parents may hurt a child's ability to identify and control emotions, according to a longitudinal study. Exposure to conflict and violence in the home can shape children's neurobiological, cognitive, and behavioral responses.
  • Asian Americans lower insulin resistance on traditional diet
    Asian Americans have been shown to lower insulin resistance on a traditional diet, researchers report. One part of this puzzle may lie in the transition from traditional high-fiber, low-fat Asian diets to current westernized diets, which may pose extra risks for those of Asian heritage, says the sen...
  • Nature's designs inspire research into new light-based technologies
    Solutions required for progress on the frontiers of photonics technology are close at hand: in nature, when viewed through the perspective of engineer, says an optics researcher.
  • Babies learn words differently as they age, researcher finds
    Researcher has found that toddlers learn words differently as they age, and a limit exists as to how many words they can learn each day. These findings could help parents enhance their children's vocabularies and assist speech-language professionals in developing and refining interventions to help c...
  • Nemo can travel great distances to connect populations: Baby clownfish travel...
    Clownfish spend their entire lives nestling in the protective tentacles of host anemones, but new research shows that as babies they sometimes travel hundreds of kilometres across the open ocean. Although the process of long-distance dispersal by reef fish has been predicted, this is the first time ...
  • The future of global agriculture may include new land, fewer harvests
    Climate change may expand suitable cropland, particularly in the Northern high latitudes, but tropical regions may becoming decreasingly suitable.
  • U.S. health system not properly designed to meet needs of patients nearing en...
    The US health care system is not properly designed to meet the needs of patients nearing the end of life and those of their families, and major changes to the system are necessary, says a new report.
  • Engineers develop algorithms to switch out and recharge battery modules in el...
    Imagine being able to switch out the batteries in electric cars just like you switch out batteries in a photo camera or flashlight. A team of engineers are trying to accomplish just that, in partnership with an engineering company. They have developed smaller units within the battery, called modules...
  • Entrepreneurs aren't overconfident gamblers, researchers say
    Leaving one's job to become an entrepreneur is inarguably risky. But it may not be the fear of risk that makes entrepreneurs more determined to succeed. A new study finds entrepreneurs are also concerned about what they might lose in the transition from steady employment to startup.
  • Lack of facial expression leads to perceptions of unhappiness, new research s...
    People with facial paralysis are perceived as being less happy simply because they can't communicate in the universal language of facial expression, a new study shows. The findings highlight the important role the face plays in everyday communication and indicates people may hold a prejudice against...
  • Nature of war: Chimps inherently violent; Study disproves theory that 'chimpa...
    Of all of the world's species, humans and chimpanzees are some of the only species to coordinate attacks on their own members. Since Jane Goodall introduced lethal inter-community killings, primatologists have debated the concept of warfare in this genus. New research from an international coalition...
  • New explanation for origin of plate tectonics: What set Earth's plates in mot...
    Geologists have a new explanation for the origin of plate tectonics. Researchers suggest it was triggered by the spreading of early continents then it eventually became a self-sustaining process.
  • New branch added to European family tree: Europeans descended from at least 3...
    Previous work suggested that Europeans descended from two ancestral groups: indigenous hunter-gatherers and early European farmers. This new study shows that there was also a third ancestral group, the Ancient North Eurasians, who contributed genetic material to almost all present-day Europeans. The...
  • Math model designed to replace invasive kidney biopsy for lupus patients
    Mathematics might be able to reduce the need for invasive biopsies in patients suffering kidney damage related to the autoimmune disease lupus. The model could also be used to monitor the effectiveness of experimental treatments for inflammation and fibrosis, researchers say.
  • Physicists heat freestanding graphene to control curvature of ripples
    Physicists have discovered that heating can be used to control the curvature of ripples in freestanding graphene. The finding provides fundamental insight into understanding the influence temperature exerts on the dynamics of freestanding graphene. This may drive future applications of the flexible ...
