4 billion-year-old relic from early solar system heading our way Posted: 12 Apr 2022 11:10 AM PDT An enormous comet -- approximately 80 miles across, more than twice the width of Rhode Island -- is heading our way at 22,000 miles per hour from the edge of the solar system. Fortunately, it will never get closer than 1 billion miles from the sun, and poses no danger to us. |
Ultrasound gave us our first baby pictures can it also help the blind see? Posted: 12 Apr 2022 06:54 AM PDT While there are no successful non-invasive therapeutics currently available for the treatment of vision loss, researchers at have come up with a new idea to address this growing problem. Currently, ophthalmologists use electronic technology to directly stimulate retinal neurons by implanting electrode devices inside the eye, a technique that requires expensive and invasive surgery. A research team is now exploring a non-surgical solution that could restore sight by using another of the five senses: Sound. |
Posted: 12 Apr 2022 06:53 AM PDT When looking at images of the magnetism generated by nano-magnets, researchers revealed the phenomenon of 'edge magnetism': the magnetic material only retained magnetism on its edge -- in fact only within 10 nanometers of the edge. |
Chimpanzees show signs of recognition toward skulls of their own species Posted: 07 Apr 2022 07:11 AM PDT Chimpanzees seem to know when a skull is chimpanzee-like, relating to the phenomenon of pareidolia that is linked to the brain's ability to detect faces. The researchers posit that chimpanzee skulls possess face-like cues, general contours, and the overall eye-nose-teeth arrangement that likely activates a network of brain regions originally evolved to detect and process faces. |
Recalled experiences surrounding death: More than hallucinations? Posted: 07 Apr 2022 07:09 AM PDT Scientific advances in the 20th and 21st centuries have led to a major evolution in the understanding of death. At the same time, for decades, people who have survived an encounter with death have recalled unexplained lucid episodes involving heightened consciousness and awareness. These have been reported using the popular -- yet scientifically ill-defined -- term 'near-death experiences'. |
