U.S. patents increased by 31 percent in fields common among Jewish scientists who fled Nazi Germany for America. Their innovative influence rippled outward for generations, as the émigrés attracted new researchers who then trained other up-and-comers.
Nanoparticles in food, sunscreen and other everyday products have many benefits. But biomedical scientists are finding that at certain doses, the particles might cause human organ damage.
The National Weather Service Storm Prediction Center has said it will add two threat levels to its weather outlooks so people aren't surprised by really bad storms on days with just a "slight risk" of tornadoes, hail or high winds. Beginning Oct. 22, forecasters can say whether slight risk days are "enhanced" or "marginal" or just plain "slight." Other categories remain, including "high" and "moderate."
Gulf Coast oyster harvests have declined dramatically in the four years since a BP PLC oil well blew in the U.S.'s worst offshore oil disaster, spilling millions of gallons off Louisiana's coast in 2010. Even after a modest rebound last year, thousands of acres of oyster beds where oil from the well washed ashore are producing less than a third of their pre-spill harvest.
Scientists have discovered a new method to efficiently generate and control currents based on the magnetic nature of electrons in semi-conducting materials, offering a radical way to develop a new generation of electronic devices.
Experts have successfully identified peptides from parasitic worms that suppress the body’s immune response. They believe this could pave the way for a new drug containing the peptide to provide relief from the symptoms of autoimmune diseases.
Scientists have come up with a promising method of treating male infertility using a synthetic version of the sperm-originated protein known as PAWP. The research promises to diagnose and treat cases of male factor infertility where a patient’s sperm is unable to initiate or induce activation of the egg to form an early embryo.
Physicists have created a tractor beam on water, providing a radical new technique that could confine oil spills, manipulate floating objects or explain rips at the beach.
Discovery of a new mechanism of drug action could lead to the next generation of drugs to treat schizophrenia. A study’s findings offer hope of a new class of drug that can act as a “dimmer switch” to control schizophrenia, without causing some of the common side effects associated with current anti-psychotic medicines.
People around the world this weekend looked up at the sky to view a lunar phenomenon: the supermoon. Here are a few amazing pictures of the event.
In our constantly connected, information-rich society, some drivers are jumping at the chance to let auto insurance companies monitor their driving habits in return for a handsome discount on their premiums. What these drivers may not know is that they could be revealing where they are driving, a privacy boundary that many would not consent to cross.
Researchers have announced the development of the first reported complex three-dimensional model made of brain-like cortical tissue that exhibits biochemical and electrophysiological responses and can function in the laboratory for months. The engineered tissue model offers new options for studying brain function, disease, trauma and treatment.
As hemp makes a comeback in the U.S. after a decades-long ban on its cultivation, scientists are reporting that fibers from the plant can pack as much energy and power as graphene, long-touted as the model material for supercapacitors.
A new technique that transforms stinky, air-polluting landfill gas could produce the sweet smell of success as it leads to development of a fuel cell generating clean electricity for homes, offices and hospitals, researchers say. The advance would convert methane gas into hydrogen.
Bee, snake or scorpion venom could form the basis of a new generation of cancer-fighting drugs, scientists say. They have devised a method for targeting venom proteins specifically to malignant cells while sparing healthy ones, which reduces or eliminates side effects that the toxins would otherwise cause.
