Hidden under the vegetation and crops of the Eria Valley, in León, Spain, there is a gold mining network created by the Romans two thousand years ago, as well as complex hydraulic works, such as river diversions, to divert water to the mines of the precious metal. Researchers made the discovery with an airborne laser teledetection system.
Modern hand dryers are much worse than paper towels when it comes to spreading germs, according to new research. A study found that airborne germ counts were 27 times higher around jet air dryers in comparison with the air around paper towel dispensers.
A new study shows that senior citizens who run several times a week for exercise expend about the same amount of energy walking as a typical 20-year-old. But older people who walk for exercise rather than jog expend about the same amount of energy walking as older, sedentary adults, and expend up to 22 percent more energy walking than the 20-something crowd.
Critical new understanding of the disease cycle of a wheat virus will help farmers around the world protect their wheat crops from a devastating disease and major yield losses. A researcher has identified that wheat seed is critical for the dissemination of wheat streak mosaic virus and its persistence between successive growing seasons.
Perth fishermen have helped stop a nasty crab invading West Australian waters that could have devastated local marine biodiversity. Introduced pests like this are one of the greatest threats to global marine biodiversity.
Female bats are fussier than males when it comes choosing where to eat in urban areas, according to new research. Town and city planners must take the needs of females into account when managing urban woodlands, to prevent a decline in numbers of certain bat species.
The El Niño Southern Oscillation (ENSO) is an ocean-atmosphere fluctuation of air pressure and sea surface temperature. Now, scientists have shown that large outbreaks of plague in Madagascar tend to coincide with the timing of ENSO events.
Scientists are wrapping up a two-year study to determine the best combination of corn hybrids, planting dates and maturity to maintain yield and maximize water-use efficiency.
William Beaumont was an American army surgeon who was the first person to observe and study human digestion as it occurs in the stomach. As a young army surgeon, Beaumont was asked to treat a shotgun wound. The patient, Alexis St. Martin, survived but was left with a permanent opening into his stomach from the outside. Famously, Beaumont studied St. Martin for years.
Aiming to discern discrete neural circuits, researchers have tracked electrical activity in the brains of people who alternately imagined scenes or watched videos. They found that, as real as that daydream may seem, its path through your brain runs opposite reality.
Premier Matteo Renzi added his voice to a chorus of outrage across Italy today after the country's highest court threw out a conviction against a Swiss businessman for some 3,000 asbestos-related deaths blamed on contamination from a construction company. The Court of Cassation has ruled that the statute of limitations expired in the environmental negligence case.
A British-led consortium has announced an ambitious space mission named Lunar Mission One that plans to land a robotic probe in the southern polar region of the moon in about a decade. The project will be solely funded by money raised through donations from the public. In order to achieve this, the project is using the funding platform Kickstarter to finance the next phase of development.
Research has yielded the first complete structure of one of the flu virus’ key machines. The machine in question, the influenza virus polymerase that was discovered 40 years ago, carries out two vital tasks for the virus.
Of all the overfished fish in the seas, luscious, fatty bluefin tuna are among the most threatened. A marine scientist is fine-tuning a technology to use mackerel surrogates to spawn the bluefin, a process he hopes will enable fisheries to raise the huge, torpedo-shaped fish more quickly and at lower cost than conventional aquaculture. The aim: to relieve pressure on wild fish stocks while preserving vital genetic diversity.
Some low-cost generic drugs that have helped restrain health care costs for decades are seeing unexpected price spikes of up to 8,000 percent, prompting a backlash from patients, pharmacists and now Washington lawmakers. Members of the Senate met today to scrutinize the recent, unexpected trend among generic medicines, which are copies of branded drugs that have lost patent protection.
