The academic sleuth facing death threats and ingratitude
Lonni Besançon devotes evenings and weekends to rarely appreciated sanitation work. By examining scientific articles after they are published and exposing shortcomings, he has made himself an enemy of both researchers and publishers. It has gone so.....»»
Astronomers" simulations support dark matter theory
Computer simulations by astronomers support the idea that dark matter—matter that no one has yet directly detected but which many physicists think must be there to explain several aspects of the observable universe—exists, according to the resear.....»»

Hubble spots magnificent barred galaxy NGC 2217
The magnificent central bar of NGC 2217 (also known as AM 0619-271) shines bright in the constellation of Canis Major (The Greater Dog), in this image taken by the NASA/ESA Hubble Space Telescope. Roughly 65 million light-years from Earth, this barre.....»»
Scientists develop strong yet reusable adhesive from smart materials
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed a smart, reusable adhesive more than 10 times stronger than a gecko's feet adhesion, pointing the way for development of reusable superglue and grippers capabl.....»»
Theoretical biologists test two modes of social reasoning and find surprising truths in simplicity
Imagine a small village where every action someone takes, good or bad, is quietly followed by ever-attentive, nosy neighbors. An individual's reputation is built through these actions and observations, which determines how others will treat them. The.....»»
