Global Precipitation Changes Linked to Human-induced Climate Change
A new study shows changes in precipitation are affected by human activities and can’t be explained by natural phenomena, such as El Niños and La Niñas. Scientists from the Lawrence Livermore National Laboratory in California published the study in the Proceedings of the National Academy of Sciences. The researchers suggest two mechanisms will probably cause […]
Scientists Make Progress on Artificial Limbs That Can Feel
Chicago researchers have made significant progress developing prosthetic limbs that can feel and touch. Writing in the Proceedings of the National Academy of Sciences, the researchers say they’ve established a foundation to develop touch-sensitive prosthetic limbs. This research could lead to a direct interface with the brain that could someday allow those who have lost […]
Cosmic Impact May Have Caused Prehistoric ‘Big Freeze’
Scientists say they may have found a link between a dramatic climate shift nearly 13,000 years ago and an asteroid or comet that struck the Canadian province of Quebec. Researchers at Dartmouth College say the comet/asteroid strike took place at the beginning of a global cooling event known as the Younger Dryas stadial or the […]
Study: Diet Changes May Have Been Crucial Step in Becoming Human
A change in diet about 3.5 million years ago may have set hominid species on a path to becoming human, according to a study led by the University of Colorado, Boulder. Scientists conducted high-tech tests on the tooth enamel found in remains of ancient hominid species. The results indicated that, prior to that dietary change, […]
Living Microorganisms Found High Above Earth
Scientists have discovered a considerable number of living microorganisms, including bacteria, in the middle to upper regions of the troposphere, the region of our atmosphere that’s about seven to 20 kilometers above the Earth’s surface. Researchers from the Georgia Institute of Technology said their findings might help other scientists learn more about the role microorganisms […]
Flu Forecasts Could Soon Join Weathercasts
Imagine that one day soon when you tune in to your favorite radio or TV station for the latest weather forecast, you’re given a flu forecast as well. Adapting techniques used in modern weather prediction, scientists at Columbia University and the National Center for Atmospheric Research have come up with a way to produce localized […]
New Microbes May Hold Clues To Extraterrestrial Life
Scientists say they have found ancient microbial life in dark and very salty water some 20 meters below the surface of a frozen and isolated Antarctic lake. The finding could provide scientists with insight into how life could possibly exist in the most extreme environments on Earth as well as elsewhere throughout the cosmos. In […]
