In the three years since a new standard for gas mileage has been in effect, automakers have surpassed it each year, improving new vehicle fuel economy by about a mile per gallon annually.
While numerous studies have affirmed nature’s stress-reduction properties, scientists haven’t known the specific amount of exposure needed to induce these calming effects. Now, researchers have found that viewing 3-D videos of residential streets with varying amounts of tree canopy significantly improved participants’ physiological and psychological recovery from a stressful experience.
Major leaks from oil and gas pipelines have led to home evacuations, explosions, millions of dollars in lawsuit payouts and valuable natural resources escaping into the air, ground and water. Now, scientists say they have developed a new software-based method that finds leaks even when they’re small, which could help prevent serious incidents— and save money for customers and industry.
Frying is one of the world’s most popular ways to prepare food. But before dunking your favorite food in a vat of just any old oil, consider using olive. Scientists are reporting that olive oil withstands the heat of the fryer or pan better than several seed oils to yield more healthful food.
Fewer cords, smaller antennas and quicker video transmission may be the result of a new type of microwave circuit. The research team behind these new circuits currently holds an attention-grabbing world record.
Chemists have devised a way to see the internal structures of electronic waves trapped in carbon nanotubes by external electrostatic charges. However, these traps, or defects, in ultra-thin nanotubes can compromise their effectiveness.
Crewed missions to Mars remain an essential goal for NASA, but scientists are only now beginning to understand and characterize the radiation hazards that could make such ventures risky. A researcher says that, because of a highly abnormal and extended lack of solar activity, the solar wind is exhibiting extremely low densities and magnetic field strengths, which causes dangerous levels of hazardous radiation.
Workers punching in for the graveyard shift may be better off not eating high-iron foods at night so they don’t disrupt the circadian clock in their livers. Disrupted circadian clocks, researchers believe, are the reason that shift workers experience higher incidences of type 2 diabetes, obesity and cancer.
A new study evaluated consumers’ choice in fresh tomato selection and revealed which characteristics make the red fruit most appealing. The researchers found that the most important fresh tomato attributes were color, amount of juice when sliced and size.
A new study has found a strong link between exposure to peanut protein in household dust during infancy and the development of peanut allergy in children genetically predisposed to a skin barrier defect.
By analyzing DNA extracted from the petrous bones of skulls of ancient Europeans, scientists have identified that these peoples remained intolerant to lactose for 5,000 years after they adopted agricultural practices and 4,000 years after the onset of cheese-making.
Information and communications technology has already revolutionized industries from publishing and entertainment to education and health care– and now, it’s transportation’s turn. Two easy examples: commuters can access real-time traffic information via their mobile phones, while adaptive signal lights can sense that a car is waiting at a red light with no cross-traffic present and switch to green to accommodate it.
If growing vegetables in a box with no soil and out of direct sunlight sounds a little fishy, well, it is. Aquaponics is a relatively new way of intensified farming that combines aquaculture and hydroponics, according to a vegetable specialist.
There's a strict set of standards for organic foods. But the rules are looser for household cleaners, textiles, cosmetics and the organic dry cleaners down the street. Absent a USDA seal or certification, there are few ways to tell if those organic claims are bogus.
Today, Israeli archaeologists said they discovered a large stone with Latin engravings that lends credence to the theory that the reason Jews revolted against Roman rule nearly 2,000 ago was because of their harsh treatment.
