Cars to Harvest Energy from a Bumpy Ride

August 4, 2015 2:00 pm | by Virginia Tech | Comments

The 255 million cars on the road in the U.S. account for 40 percent of the country’s fuel consumption. Most of that fuel is wasted; only 10 to 16 percent is actually used to drive. Most of the rest is lost to heat and other inefficiencies. Now, a mechanical engineer may have a partial solution: harvesting energy from the car’s suspension.

Rethinking Death is Key to Protecting Environment

August 4, 2015 2:00 pm | by Univ. of York | Comments

Scientists first had to rethink death before they could develop a way of testing the potential harm to the environment caused by thousands of chemicals humankind uses each day. Researchers have refined the technique of survival analysis used routinely by toxicologists, biologists, medical researchers and engineers. The research could pave the way for testing the estimated 15,000 substances discovered daily.

Bonobo Communication is Similar to that of Human Infants

August 4, 2015 2:00 pm | by Univ. of Birmingham | Comments

Researchers have found that wild bonobos, our closest living relatives in the primate world, communicate in a similar manner to human infants, using a high-pitched call type, or “peep,” that requires context to be understood. The finding that bonobos use a type of call, that alters meaning depending on context, echoes the context independent manner in which human babies can also communicate.

You’ve either brought a sweater to work during the hot summer months, or have a friend, wife or mother who keeps one on the back of her chair to cope with the arctic blast of air conditioning. Now, researchers say a kind of office-climate politics has been skewed toward men, whose metabolic rates are higher and, therefore, prefer cooler temperatures than women.

Visualizing Trust: Mimicking Someone’s Pupils Leads to Increased Trust

August 3, 2015 2:05 pm | by Association for Psychological Science | Comments

People often mimic each other’s facial expressions or postures without even knowing it, but new research shows that they also mimic the size of each other’s pupils, which can lead to increased trust. The research showed that participants who mimicked the dilated pupils of a partner were more likely to trust that partner in an investment game, but only when the partner was part of the same ethnic group.
