Scientists have invented a ground-breaking new method that puts the construction of large-scale quantum computers within reach of current technology.
Scientists in Singapore have shown that a photon's shape affects how it is absorbed by a single atom. The experiment involved infrared photons some 4 meters long and Rubidium atoms less than a nanometer wide.
Physicists have published new findings examining the electrical properties of materials that could be harnessed for next-generation transistors and electronics.
Researchers have succeeded in measuring tiny changes in strong magnetic fields with unprecedented precision. In their experiments, the scientists magnetized a water droplet inside a magnetic resonance imaging (MRI) scanner, a device that is used for medical imaging. The researchers were able to detect even the tiniest variations of the magnetic field strength within the droplet. These changes were up to a trillion times smaller than the seven tesla field strength of the MRI scanner used in the experiment.
When we are in a deep slumber our brain's activity ebbs and flows in big, obvious waves, like watching a tide of human bodies rise up and sit down around a sports stadium. It's hard to miss. Now, researchers have found, those same cycles exist in wake as in sleep, but with only small sections sitting and standing in unison rather than the entire stadium. It's as if tiny portions of the brain are independently falling asleep and waking back up all the time.
A new device that could revolutionize the delivery of medicine to treat cancer as well as a host of other diseases and ailments has been outlined in a new report.
Hospitals in which the administration of epinephrine to patients whose hearts have stopped is delayed beyond five minutes have significantly lower survival rates of those patients, a new study.
New findings showed associations between psychological well-being and physical activity in adults ages 50 and older.
Scientists are using new computer models and evidence from meteorites to show that a low-mass supernova triggered the formation of our solar system.
Too little sleep takes a toll on your heart, according to a new study.
Scientists hoping to get a glimpse of molecules that control brain activity have devised a new probe that allows them to image these molecules without using any chemical or radioactive labels.
The properties of the 83rd element of the periodic table, namely, Bismuth (Bi) have been studied for more than a century and still continues to draw enormous scientific interests due to its anomalous electronic properties.
Working with human immune cells in the laboratory, researchers report they have identified a critical cellular "off" switch for the inflammatory immune response that contributes to lung-constricting asthma attacks. The switch, they say, is composed of regulatory proteins that control an immune signaling pathway in cells.
Two recently discovered genetic differences between brain cancer cells and normal tissue cells — an altered gene and a snippet of noncoding genetic material — could offer clues to tumor behavior and potential new targets for therapy, scientists report.
For the two-thirds of kidney stone patients who need more than just extra hydration to pass their stones, physicians are eager to find non-surgical ways to help. Now, a new review of the medical literature suggests alpha blockers may be useful in some cases.
A team of international archaeologists believe a pair of mummified legs on display in an Italian museum may belong to Egyptian Queen Nefertari – the favorite wife of the pharaoh Ramses II.
A new diet intervention study raises questions regarding the validity of a diet hypothesis that has dominated for more than half a century: that dietary fat and particularly saturated fat is unhealthy for most people.
Mapping the interaction of a single atom with a single photon may inform design of quantum devices, report scientists in a new article.
Poorly maintained air conditioning systems cause mold or other bacteria to spread; they often also generate drafts and are costly to operate. An alternative technology that uses ceiling panels covered in special heat-conducting film operates well below the dew point. The system offers hygienic cooling even in tropical climates, and uses up to 70 percent less energy.
Flower forms in the primrose: Biologists unlock 51.7-million-year-old genetic secret to landmark Darwin theory
Scientists have identified the cluster of genes responsible for reproductive traits in the common primrose flower (Primula vulgaris), first noted as important by Charles Darwin more than 150 years ago. Darwin hypothesized that some plant species with two distinct forms of flower, where male and female reproductive organs were of differing lengths, had evolved that way to promote out-crossing by insect pollinators.
