In a paper titled "Search for Artificial Stellar Sources of Infrared Radiation," he suggested that advanced extra-terrestrial intelligences (ETIs) could be found by looking for signs of artificial structures so large that they encompass entire star systems (also known as megastructures). Since then, many scientists have co
When I first wrote about small-molecule structures obtained by microED (electron diffraction), I wondered if there were some way to get absolute stereochemistry out of the data (as you can with X-ray diffraction under the right conditions). Several groups have been working on just that problem, and this new paper now shows that it can be done ( commentary here at Science ). As usual, I Am Not a C

The world recently discovered that disastrous deterioration in the health of most of the planet's ecosystems means that a million species are threatened with extinction. This is among the findings of the most thorough ever survey of the state of the biosphere, carried out by the Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES).
People who see themselves as being in a higher social class may tend to have an exaggerated belief that they are more adept than their equally capable lower-class counterparts, and that overconfidence can often be misinterpreted by others as greater competence in important situations, such as job interviews, according to research published by the American Psychological Association.

Identifying the optimal drug treatment is like hitting a moving target. To stop disease, small-molecule drugs bind tightly to an important protein, blocking its effects in the body. Even approved drugs don't usually work in all patients. And over time, infectious agents or cancer cells can mutate, rendering a once-effective drug useless.

In a new study, researchers have propelled water nanodroplets across a graphene surface at speeds of up to 250 km (155 miles) per hour—which, for comparison, is about twice as fast as a sprinting cheetah. The water droplets' ultrafast velocities don't require any pump, but instead occur simply due to the geometric patterns on the graphene surface, which create different contact angles at the front
In the first edition of On the Origin of Species, Charles Darwin mentions dogs 54 times. He does so mainly because the extraordinary variation between dog breeds provides a marvellous illustration of the power of selection. For most of the roughly 15,000 years since their domestication, dogs were selected by humans for their usefulness as hunters, retrievers, herders, guards or companions.

Some consumers place importance on locally grown or organic food. Others want the products they purchase to look and taste good. Yet others focus on low prices. However, no matter what their other requirements, everyone would like their food to be free of contaminants, which makes it quite worrying that over 97 percent of European food products contain pesticide residues. The problem is that curre

Our oceans and the complex "conveyer belt" system of currents that connects them play an important role in regulating global climate.
