Researchers from North Carolina State University and the Chinese Academy of Sciences have found an easy way to modify the molecular structure of a polymer commonly used in solar cells. Their modification can increase solar cell efficiency by more than 30 percent.
Sharks in Western Australia are going to find themselves tweeting to swimmers that they are heading to shallow waters looking for a human sized snack.
Open collaboration – which has brought the world Bitcoin, TEDx and Wikipedia – is likely to expand into new domains and displace traditional organizations, according to a paper in a journal of the Institute for Operations Research and the Management Sciences (INFORMS).
There's a map of an ancient Syrian trade route that shows how one city's political sway extended farther than once thought. This map isn't a time-worn and mysterious etching on a stone tablet. Turns out it's easily found on a different type of tablet – the kind with apps.
Fourteen mountain peaks on Earth stand taller than 8,000 meters (26,247 feet). The tallest of these “eight-thousanders” is Mount Everest, the standard to which all other mountains are compared. The Nepalese name for the mountain is Sagarmatha: “mother of the universe.”
Pine Island Glacier is one of the biggest routes for ice to flow from Antarctica into the sea. The floating ice shelf at the glacier's tip has been melting and thinning for the past four decades, causing the glacier to speed up and discharge more ice.
Two INSERM research teams led by Pier Vincenzo Piazza and Giovanni Marsicano (INSERM Unit 862 "Neurocentre Magendie" in Bordeaux) recently discovered that pregnenolone, a molecule produced by the brain, acts as a natural defence mechanism against the harmful effects of cannabis in animals.
Researchers at Aalto University have determined how emotions are experienced in the body.
Global average temperatures will rise at least 4°C by 2100 and potentially more than 8°C by 2200 if carbon dioxide emissions are not reduced according to new research published in Nature. Scientists found global climate is more sensitive to carbon dioxide than most previous estimates.
The challenge of supplying clean, safe drinking water to an expanding world population comes down to money, MIT economist Franklin Fisher says: We are surrounded by water — it covers 71 percent of Earth’s surface — and industrial-scale desalination has operated successfully around the world for many years.
A new study quantifies for the first time future losses in deep-sea marine life, using advanced climate models. Results show that even the most remote deep-sea ecosystems are not safe from the impacts of climate change.
Randy Olson loves to see a program evolve.
Earth's crust was unstable in the Archean eon and dripped down into the mantle
Model calculations indicate that the extreme density of the base of the thickened primary crust caused it to subside into Earth's mantle.
Most large, clinical trials of vitamin supplements, including some that have concluded they are of no value or even harmful, have a flawed methodology that renders them largely useless in determining the real value of these micronutrients, a new analysis suggests.
Researchers are developing computers capable of "approximate computing" to perform calculations good enough for certain tasks that don't require perfect accuracy, potentially doubling efficiency and reducing energy consumption.
When considering the behavior of bacteria, the word "social" doesn't often come to mind. Yet some bacteria are quite social, chief among them Myxococcus xanthus, a soil-dwelling bacterium that organizes itself into multi-cellular, three-dimensional structures made up of thousands of cells that work together to hunt for food and survive under harsh conditions.
A mathematical pattern of movement called a Lévy walk describes the foraging behavior of animals from sharks to honey bees, and now for the first time has been shown to describe human hunter-gatherer movement as well. The study, led by University of Arizona anthropologist David Raichlen, was recently published in the Proceedings of the National Academy of Sciences.
Citing an overabundance in the use of antibiotics by the agriculture and aquaculture industries that poses a threat to public health, economics professor Aidan Hollis has proposed a solution in the form of user fees on the non-human use of antibiotics.
We all know how entitled millennials are supposed to be. Well, the next generation isn't looking so hot, either. They're stuck indoors, clasped to the bosoms of anxious parents. Is it any wonder they are addicts, addicted to interacting online.
Researchers have developed a way to microscopically view battery electrodes while they are bathed in wet electrolytes, mimicking realistic conditions inside actual batteries. While life sciences researchers regularly use transmission electron microscopy to study wet environments, this time scientists have applied it successfully to rechargeable battery research.
