Scientists in the UK are studying the genes of mice with the goal of tracking human migration patterns throughout history. York University professor Jeremy Searle and colleagues collected genetic data of house mice from more than 100 locations across the UK. One strain in particular was noted to have arrived with the Vikings. Scientists say rodents provide a historic map of past human ventures because the small rodents often accompanied travelers when they set off in search of new places to...

For the first time ever, scientists will use satellites in space to monitor the fluctuations of endangered species populations. The scientists will use satellite photos to count and monitor giant kangaroo rats, a key indicator for the health of a dry plains environment. The photos will be obtained from the same satellites the Israeli defense forces use, and will be compared with 30 years of satellite images released this month by the U.S. Geological Survey.  Researchers aim to use this...

U.S. scientists say they've found a tiny amount of inhaled or intravenous hydrogen sulfide greatly improves the survival of rats with extreme blood loss. Fred Hutchinson Cancer Research Center researchers said they used hydrogen sulfide to induce a state of reversible metabolic hibernation as a way to reduce death from insufficient blood supply to organs and tissues in a rat model of lethal hemorrhage. The study determined 75 percent of rats given inhaled hydrogen sulfide and 67 percent...
