A study has revealed that a drug that inhibits a molecule called prostaglandin E2 increases survival rates in mice infected with a lethal dose of the H1N1 flu virus.
Researchers who run one of four large experiments at the Large Hadron Collider have announced one of the most genuinely exciting observations to come out of the 27 km super-collider so far– an exotic particle that cannot be explained by current theories.
Researchers have developed a simple approach to applying a coating of thin, flat nanoplatelets— using a common spray gun— that spontaneously self-assemble into “nanowalls.” The nanowalls act as rigid barriers that prevent oxygen gas from reaching the surface of objects prone to corrosion.
A pH-sensitive microchip, invented by chemists, could improve postoperative care for patients with knee replacements and other surgical implants.
An Apollo 11 lunar surface checklist sheet was among the coveted items— sold at an auction of space exploration artifacts— that fetched for more than the pre-sale estimate.
Passwords, credit cards and other sensitive data are at risk after security researchers discovered a problem with an encryption technology used to securely transmit email, e-commerce transactions, social networking posts and other Web traffic. Security experts say the threat, known as Heartbleed, is serious, partly because it remained undiscovered for more than two years.
The Miccosukee gooseberry is on the verge of extinction, but a geneticist believes genetic variation is the key to its survival. The plant, which has been listed as a federally threatened species for nearly three decades, is found in only two counties in the U.S.
Researchers in the emerging field of synthetic biology have designed a tool box of small genetic components that act as intracellular switches, logic gates, counters and oscillators.
Using a laser to place individual rubidium atoms near the surface of a lattice of light, scientists have developed a new method for connecting particles— one that could help in the development of powerful quantum computing systems.
Drugs used to block copper absorption for a rare genetic condition may find an additional use as a treatment for certain types of cancer.
Archaeologists are challenging the traditional view that Neanderthal childhood was difficult, short and dangerous. A research team is offering a new and distinctive perspective that suggests that Neanderthal children experienced strong emotional attachments with their immediate social group, used play to develop skills and maintained a significant role in their society.
Experiments have explained the behavior of electrons at tiny step edges on titanium oxide surfaces. This is important for solar cell technology and novel, more effective catalysts.
A team of researchers has transformed Google Glass into a powerful, wearable medical testing laboratory. They developed an application that reads dozens of different types of diagnostic tests for malaria, prostate cancer and HIV, to name a few.
According to EU guidelines, the new compound R1234yf should, in the future, be used as the refrigerant in air-conditioning systems for automobiles. But the compound is inflammable, and chemists have shown that combustion of the cooling agent leads to the formation of the highly toxic carbonyl fluoride.
One theory about the origin of life is that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world. Recent research has found that it may not have been as easy as previously assumed. Instead, the finds could provide a focus for the search for life on other planets.
