| Global warming led to dwarfism in mammals -- twice Posted: 02 Nov 2013 06:55 AM PDT Mammal body size decreased significantly during at least two ancient global warming events, a new finding that suggests a similar outcome is possible in response to human-caused climate change, according to paleontologists. |
| Synaptic transistor learns while it computes Posted: 02 Nov 2013 06:55 AM PDT It doesn't take a Watson to realize that even the world's best supercomputers are staggeringly inefficient and energy-intensive machines. Our brains have upwards of 86 billion neurons, connected by synapses that not only complete myriad logic circuits; they continuously adapt to stimuli, strengthening some connections while weakening others. We call that process learning, and it enables the kind of rapid, highly efficient computational processes that put Siri and Blue Gene to shame. |
| Can putting your child before yourself make you a happier person? Posted: 31 Oct 2013 02:56 PM PDT While popular media often depicts highly-involved parents negatively as "helicopter parents" or "tiger moms, how does placing one's children at the center of family life really affect parental well-being? New research finds that parents who prioritize their children's well-being over their own are not only happier, but also derive more meaning in life from their child-rearing responsibilities. |
