| 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. |
| Crashing rockets could lead to novel sample-return technology Posted: 01 Nov 2013 02:23 PM PDT In early 2013, University of Washington students launched rockets from kites and balloons into a dry Nevada lakebed, early tests of a concept to collect and return samples from forbidding environments. |
| A galaxy within us: Our gut microbiota and how it can be programmed by food Posted: 01 Nov 2013 09:54 AM PDT Who would have thought that the human body contains over 10 times the amount of bacterial cells as human cells? These bacteria - now collectively called the gut microbiota - number in their trillions and are made up of more than a 1,000 different species most of which are beneficial in some way. |
