A study by researchers at the University of Granada has demonstrated that mortality among cyclists varies widely depending on the age and sex of the population. Male cyclists, above all those aged between 15 and 24 years, are more...
SEQUOIA AND KINGS CANYON, Calif. --Longer, more severe, and hotter droughts and a myriad of other threats, including diseases and more extensive and severe wildfires, are threatening to transform some of the world's temperate forests, a new study published...
A new technique for estimating the mass of the Milky Way galaxy promises more reliable results, especially when it’s applied to large datasets generated by current and future surveys, according to new research. It’s impossible to “weigh” a galaxy simply...
Researchers have created the first complete list of all known vascular plant species in the Americas. The searchable database contains nearly 125,000 species representing one-third of all known vascular plants worldwide. Vascular plants are land plants with specialized internal-transport and vertical-support...
Vertical axis wind turbines, which may have fewer effects on birds and nearby people, could increase public support for new wind energy installations, new research suggests. With global carbon emissions on the rise, wind power continues to be an attractive...
NASA's two Voyager spacecraft are hurtling through unexplored territory on their road trip beyond our solar system. Along the way, they are measuring the interstellar medium, the mysterious environment between stars. NASA's Hubble Space Telescope is providing the road...
Astronomers using the MUSE instrument on ESO’s Very Large Telescope in Chile, and the NASA/ESA Hubble Space Telescope, have made the most precise test yet of Einstein’s general theory of relativity outside the Milky Way. The nearby galaxy ESO...
A team of astronomers led by Tomoharu Oka, a professor at Keio University in Japan, has found an enigmatic gas cloud, called CO-0.40-0.22, only 200 light years away from the center of the Milky Way. What makes CO-0.40-0.22 unusual...
With their special microscopes, experimental physicists can already observe single molecules. However, unlike conventional light microscopes, the raw image data from some ultra-high resolution instruments first have to be processed for an image to appear. For the ultra-high resolution...
Some actions, like yawning and scratching, can spread from one person to another. New research finds that socially contagious itching is hardwired in the brain. Studying mice, the scientists have identified what occurs in the brain when a mouse feels...
