| Tasmanian tiger's jaw was too small to attack sheep, study shows Posted: 31 Aug 2011 06:00 PM PDT Australia's iconic thylacine, or Tasmanian tiger, was hunted to death in the early Twentieth century for allegedly killing sheep; however, a new study has found that the tiger had such weak jaws that its prey was probably no larger than a possum.  |
| 'Plastic bottle' solution for arsenic-contaminated water threatening 100 million people Posted: 31 Aug 2011 05:59 PM PDT With almost 100 million people in developing countries exposed to dangerously high arsenic levels in their drinking water, and unable to afford purification technology, scientists described a simple, inexpensive method for removing arsenic based on chopped up pieces of plastic beverage bottles coated with a nutrient found in many foods and dietary supplements.  |
| Marshmallow test points to biological basis for delayed gratification Posted: 31 Aug 2011 01:02 PM PDT A landmark study in the late 1960s and early 1970s used marshmallows and cookies to assess the ability of preschool children to delay gratification. A newly published follow-up revisits some of the same children, now adults.  |
| Posted: 31 Aug 2011 01:00 PM PDT It's all about the grandkids! That's what a team of biologists has learned about promiscuous female birds and why they mate outside their social pair.  |
| 'Gene overdose' causes extreme thinness Posted: 31 Aug 2011 01:00 PM PDT Scientists have discovered a genetic cause of extreme thinness for the first time. The research shows that people with extra copies of certain genes are much more likely to be very skinny. In one in 2000 people, part of chromosome 16 is duplicated, making men 23 times and women five times more likely to be underweight.  |
| Not tonight deer: A new birth control vaccine helps reduce urban deer damage Posted: 31 Aug 2011 12:53 PM PDT A new birth control vaccine for white-tailed deer -- a growing nuisance in urban areas for gardens and landscaping -- eliminates the dangerous reproductive behavior behind the annual autumn surge in automobile-deer collisions. The vaccine is just becoming commercially available in some U.S. states.  |
| Word association: Study matches brain scans with complex thought Posted: 31 Aug 2011 08:59 AM PDT Researchers have for the first time matched images of brain activity with categories of words related to the concepts a person is thinking about. The results could lead to a better understanding of how people consider meaning and context when reading or thinking.  |
| Great tits sing low to be loved or high to be heard Posted: 31 Aug 2011 05:17 AM PDT Male great tits of this species try to sound sexy to females by singing complex or high performance songs, but may find their attempts hindered by human-generated noise. Birds have been found to adjust their songs when confronted with urban noise, which seems an effective strategy to deal with masking interference. However, such change may come at a cost of reduced attractiveness.  |
| New chemical reagent turns mouse brain transparent Posted: 31 Aug 2011 05:15 AM PDT Researchers in Japan have developed a ground-breaking new aqueous reagent which literally turns biological tissue transparent. Experiments using fluorescence microscopy on samples treated with the reagent have produced vivid 3-D images of neurons and blood vessels deep inside the mouse brain. Highly effective and cheap to produce, the reagent offers an ideal means for analyzing the complex organs and networks that sustain living systems.  |
