| Putting the Sloth in Sloths: Arboreal Lifestyle Drives Slow Motion Pace Posted: 20 Jul 2016 02:04 PM PDT Scientists set out to measure the energetics of wild two- and three-toed sloths at a field site in in northeastern Costa Rica. The purpose of the study was to help explain why arboreal folivores are indeed so rare and why more animals have not evolved to take advantage of a widespread ecological niche. |
| Asteroid that formed moon's Imbrium Basin may have been protoplanet-sized Posted: 20 Jul 2016 10:56 AM PDT The asteroid that slammed into the moon 3.8 billion years ago creating the Imbrium Basin may have had a diameter of at least 150 miles, according to a new estimate. The work helps explain puzzling geological features on the moon's near side, and has implications for understanding the evolution of the early solar system. |
| Social robots: Programmable by everyone Posted: 20 Jul 2016 06:46 AM PDT Social robots can be used in the educational or health system, where they would support trainers and therapists in their work. The robots can be programmed to practice vocabulary with children or to make rehabilitation exercises with stroke patients. |
| A chair for getting fit and trim Posted: 20 Jul 2016 06:46 AM PDT Getting fit and athletic -- while sitting? Researchers are developing an active chair. At first glance, the chair looks just like another other reclining chair with a footrest you would find in a living room in front of the TV. But upon closer inspection, the chair is actually connected to a virtual avatar and has all manner of technical refinements. |
| Medieval water power initiated collapse of salmon stocks Posted: 20 Jul 2016 06:44 AM PDT Salmon largely disappeared from our waters due to the construction of water mills, ecologists now conclude. The construction of water mills caused the destruction of the gravel beds in streams, making them unsuitable for salmon to spawn. Whereas it was previously thought that water contamination was the most likely explanation, archival research demonstrates that salmon stocks had already dwindled prior to the invention of the steam engine. |
| After the age of dinosaurs came the age of ant farmers Posted: 20 Jul 2016 06:42 AM PDT Soon after the demise of the dinosaurs, ants learned how to farm. The story of the mutualism between leafcutter ants and their fungal crop culminates in industrial-scale farming that surpasses even human farming in its efficiency. |
| Microbe drives species apart: Tiny microbe turns tropical butterfly into male killer Posted: 19 Jul 2016 06:48 PM PDT A male-killing microbe has now been identified in a tropical butterfly called the African Queen, which leads to the death of all sons when a mother is infected. |
