| Scientists work their magic on 'shrunken finger illusion' Posted: 31 Mar 2016 10:34 AM PDT What happens when you rest a chopped ping pong ball on your finger and look at it from above? Experimental psychologists have shown that our visual system fills in the bottom part of the ball, even though we know it's missing. This makes our finger feel unusually short, as if to compensate for the 'complete' ball. The findings indicate that the completion is due to our visual system, not our imagination. |
| 3-D 'mini-retinas' grown from mouse and human stem cells Posted: 31 Mar 2016 10:34 AM PDT Stem cell science has progressed so that researchers can now share recipes for making human retinas -- the part of the eye that is sensitive to light. Researchers now have another efficient way to make 3-D retina organoids, which mimic the organ's tissue organization, from mouse or human stem cells. Their version of 'mini-retinas' offers new perspectives on retina growth, injury, and repair. |
| Harlequin ladybirds are conquering the world at great speed Posted: 31 Mar 2016 09:23 AM PDT The arrival and subsequent dramatic increase in the number of the invasive alien harlequin ladybird in many countries has been met with considerable trepidation by the scientific community. 'The rapid spread of this species has inspired biologists to study the process of invasion on a global scale. |
| Laser cloaking device could help us hide from aliens Posted: 31 Mar 2016 07:59 AM PDT Two astronomers suggest humanity could use lasers to conceal the Earth from searches by advanced extraterrestrial civilizations. |
