| Images capture split personality of dense suspensions Posted: 30 Mar 2012 01:49 PM PDT Stir lots of small particles into water, and the resulting thick mixture appears highly viscous. When this dense suspension slips through a nozzle and forms a droplet, however, its behavior momentarily reveals a decidedly non-viscous side. Physicists have recorded this surprising behavior in laboratory experiments using high-speed photography that can capture action taking place in one hundred-thousandths of a second or less. |
| Bees 'self-medicate' when infected with some pathogens Posted: 30 Mar 2012 08:10 AM PDT Honey bees "self-medicate" when their colony is infected with a harmful fungus, bringing in increased amounts of antifungal plant resins to ward off the pathogen. |
| Crocodiles trump T. rex as heavyweight bite-force champions, new study shows Posted: 30 Mar 2012 08:02 AM PDT Biologists have found in a study of all 23 living crocodilian species that crocodiles can kill with the strongest bite force measured for any living animal. The study also revealed that the bite forces of the largest extinct crocodilians exceeded 23,000 pounds, a force two-times greater than the mighty Tyrannosaurus rex. |
