For men, online generosity is a competition

In competitive helping in donations made to online fundraising pages, males respond competitively to donations made by other males, but only when giving to an attractive female fundraiser. Female donors do not compete in this way. These findings suggest a role for sexual selection in explaining conspicuous generosity.If you are looking to raise money online for your favorite cause, listen up. A real-world analysis of human behavior reported in the Cell Press journal Current Biology on April...

Scientists develop mesh that captures oil--but lets water through

This mesh, which is covered in a coating invented at The Ohio State University, captures oil (red) while water (blue) passes through.The unassuming piece of stainless steel mesh in a lab at The Ohio State University doesn't look like a very big deal, but it could make a big difference for...

Iowa State anthropologist finds female chimps more likely to use tools when hunting

Jill Pruetz says the environment and social tolerance may explain why savanna chimps, particularly females, are more likely to hunt with tools.It was a discovery that changed what researchers knew about the hunting techniques of chimpanzees. In 2007, Jill Pruetz first reported savanna chimps at her research site in Fongoli, Senegal,...

Search for advanced civilizations beyond Earth finds nothing obvious in 100,000 galaxies

This is a false-color image of the mid-infrared emission from the Great Galaxy in Andromeda, as seen by Nasa's WISE space telescope.  The orange color represents emission from the heat of stars forming in the galaxy's spiral arms. The G-HAT team used images such as these to search 100,000 nearby galaxies for unusually large amounts of this mid-infrared emission that might arise from alien civilizations.After searching 100,000 galaxies for signs of highly advanced extraterrestrial life, a team of scientists using observations from NASA's WISE orbiting observatory has found no evidence of advanced civilizations in...

Spitzer, OGLE spot planet deep within our galaxy

This artist's conception shows a planet half as massive as Jupiter located 13,000 light-years from Earth. It was detected by the Optical Gravitational Lensing Experiment and NASA's Spitzer Space Telescope using microlensing. Spitzer provided parallax measurements that allowed scientists to determine how far away the planet is.NASA's Spitzer Space Telescope has teamed up with a telescope on the ground to find a remote gas planet about 13,000 light-years away, making it one of the most distant...

Dark Energy Survey creates detailed guide to spotting dark matter

This is the first Dark Energy Survey map to trace the detailed distribution of dark matter across a large area of sky. The color scale represents projected mass density: red and yellow represent regions with more dense matter. The dark matter maps reflect the current picture of mass distribution in the universe where large filaments of matter align with galaxies and clusters of galaxies. Clusters of galaxies are represented by gray dots on the map -- bigger dots represent larger clusters. This map covers three percent of the area of sky that DES will eventually document over its five-year mission.Scientists on the Dark Energy Survey have released the first in a series of dark matter maps of the cosmos. These maps, created with one of the world's most powerful...
