| Natural scale caterpillar soft robot is powered and controlled with light Posted: 18 Aug 2016 07:26 AM PDT Researchers, using the liquid crystal elastomer technology have demonstrated a bioinspired micro-robot capable of mimicking caterpillar gaits in natural scale. The 15-millimeter long soft robot harvests energy from green light and is controlled by spatially modulated laser beam. Apart from traveling on flat surfaces, it can also climb slopes, squeeze through narrow slits and transport loads. |
| Venus-like exoplanet might have oxygen atmosphere, but not life Posted: 18 Aug 2016 07:26 AM PDT The distant planet GJ 1132b intrigued astronomers when it was discovered last year. Located just 39 light-years from Earth, it might have an atmosphere despite being baked to a temperature of around 450 degrees Fahrenheit. But would that atmosphere be thick and soupy or thin and wispy? New research suggests the latter is much more likely. |
| Pre-Hispanic Mexican civilization may have bred and managed rabbits and hares Posted: 17 Aug 2016 11:25 AM PDT Humans living in the pre-Hispanic Mexican city of Teotihuacan may have bred rabbits and hares for food, fur and bone tools, according to a new study. |
| For sensation-seekers, the color red can elicit rebelliousness, study finds Posted: 17 Aug 2016 10:17 AM PDT The widespread use of the color red to signal danger can actually be counterproductive for certain people, says new research. Under certain conditions, say investigators, the color red can arouse "noncompliant behavior" - basically, a rebellious streak - for a certain sensation-seeking segment of the population. |
| How we escaped the Big Bang: New theory on moving through time Posted: 17 Aug 2016 07:15 AM PDT A physicist is challenging the conventional view of space and time to show how the world advances through time. In her new research, she argues that T violation, or a violation of time reversal (T) symmetry, is forcing the universe and us in it, into the future. |
