| Ingestible robot operates in simulated stomach Posted: 12 May 2016 01:06 PM PDT In experiments involving a simulation of the human esophagus and stomach, researchers have demonstrated a tiny origami robot that can unfold itself from a swallowed capsule and, steered by external magnetic fields, crawl across the stomach wall to remove a swallowed button battery or patch a wound. |
| Small blue galaxy could shed new light on Big Bang Posted: 12 May 2016 11:29 AM PDT A faint blue galaxy nicknamed Leoncino, or 'little lion,' about 30 million light-years from Earth and located in the constellation Leo Minor has been identified by astronomers as possessing qualities that could shed new light on conditions at the birth of the universe. |
| How light is detected affects the atom that emits it Posted: 12 May 2016 11:29 AM PDT Flick a switch on a dark winter day and your office is flooded with bright light, one of many everyday miracles to which we are all usually oblivious. A physicist would probably describe what is happening in terms of the particle nature of light. An atom or molecule in the fluorescent tube that is in an excited state spontaneously decays to a lower energy state, releasing a particle called a photon. When the photon enters your eye, something similar happens but in reverse. The photon is absorbed by a molecule in the retina and its energy kicks that molecule into an excited state. Light is both a particle and a wave, and this duality is fundamental to the physics that rule the Lilliputian world of atoms and molecules. Yet it would seem that in this case the wave nature of light can be safely ignored. Researcher might now give you an argument about that. |
| When dung beetles dance, they photograph the firmament Posted: 12 May 2016 09:54 AM PDT The discovery that dung beetles use the light of the Milky Way to navigate in the world has received much praise. Researchers have now taken a new step in understanding the existence of these unique beetles: when the beetles dance on top of a ball of dung, they simultaneously take a photograph -- a snapshot -- of how celestial bodies are positioned. |
| Posted: 12 May 2016 05:51 AM PDT Aesthetic treatments based on botulin toxin affect the perception of emotions, new research shows. The consequence of having Botox injected, scientists explain, depends on a temporary block of proprioceptive feedback, a process that helps us understand other people's emotions by reproducing them on our own bodies. |
| Mighty mealworms: Solution for food insecurity, pollution Posted: 11 May 2016 01:10 PM PDT Can mealworms be used to solve two global problems? Researchers suggest that yes: for food sustainability and plastic pollution. |
