Earthquakes, tsunamis, and other natural disasters often showcase the worst in human suffering -- especially when those disasters strike populations who live in rapidly growing communities in the developing world with poorly enforced or non-existent building codes. This week in Cancun, researchers...

Much like the inside of an operating room, in the clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., engineers worked meticulously to implant part of the eyes of the James Webb Space Telescope. They scrubbed up and suited up to perform one of the most delicate performances of their...

After taking a rented camper outfitted with special equipment to measure methane on a cross-continent drive, a scientist has found that methane emissions across large parts of the US are higher than currently known, confirming what other more local studies have found. Fuente :...
Taking before and after pictures of the Martian terrain, researchers have identified nearly 250 fresh impact craters on the Red Planet. The results provide scientists with a better yardstick to estimate how frequently craters are blasted on Mars, allowing them to assess recently formed features...
The brain forms complex new circuits after damage to compensate for lost function, often far from the damaged region, life scientists report. The new study identified the exact regions of the brain that take over when the brain's hippocampus is damaged, and is the first demonstration of such neural...
Chances are you know how many miles your car logs for each gallon or tankful of gas, but you probably have only a foggy idea of how much energy your house consumes, even though home energy expenditures often account for a larger share of the household budget. Fuente :...
Suicide risk is higher among military personnel with more lifetime TBIs, even after controlling for clinical symptom severity. Results of the study show that multiple TBIs, which are common among military personnel, may contribute to increased risk for suicide. Fuente :...
