An association between childhood asthma and prenatal exposure to two phthalates used in a diverse array of household products has been discovered by researchers. Phthalates are used in everything from synthetic fragrances to plastic food containers, vinyl flooring, insect repellent, shower curtains, even steering wheels and dashboards ("new car smell" contains phthalates).
The remains of King Richard III -- the last English monarch to die in battle -- were found under a car park in Leicester by archaeologists. The forensic imaging team used whole body CT scans and micro-CT imaging of injured bones to analyze trauma to the 500-year-old skeleton carefully, and to determine which of the King's wounds might have proved fatal.
For decades scientists have believed that galaxy mergers usually result in the formation of elliptical galaxies. Now, for the the first time, researchers have found direct evidence that merging galaxies can instead form disc galaxies, and that this outcome is in fact quite common. This surprising result could explain why there are so many spiral galaxies like the Milky Way in the Universe.
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.
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 Land Transit Authority, the researchers compared their system to one currently in use in Singapore, which charges drivers with dashboard-mounted transponders a toll for entering congested areas.
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.
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 optimal solution to a nuanced problem.
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 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 senior author of the study.
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 children with language delays.
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 that the high level exchange of offspring between distant populations has been observed.
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, and a battery management system that will allow them to swap out and recharge the modules.
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.
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 those with facial paralysis because of their disability.
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 of ape researchers has shed new light on the subject, suggesting that human encroachment and interference is not, as previous researchers have claimed, an influential predictor of chimp-on-chimp aggression.
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 research also reveals an even older lineage, the Basal Eurasians.
