Storms on Jupiter are disturbing the planet's colorful belts Posted: 22 Aug 2019 10:04 AM PDT Coordinated observations of Jupiter in early 2017 by six ground-based telescopes and Hubble allowed astronomers to study the evolution of bright plumes and connect them with cloud movements deep in the planet. They show that these plumes originate 80 kilometers below the surface cloud deck and rise up quickly into the stratosphere, where supercooled ammonia freezes to form ammonia ice clouds. The plumes create disturbances in the belts and even change their color. |
Scratching the surface of how your brain senses an itch Posted: 22 Aug 2019 09:55 AM PDT Light touch plays a critical role in everyday tasks, such as picking up a glass or playing a musical instrument, as well as for detecting the touch of, say, biting insects. Researchers have discovered how neurons in the spinal cord help transmit such itch signals to the brain. The findings could help contribute to a better understanding of itch and could lead to new drugs to treat chronic itch, which occurs in such conditions as eczema, diabetes and even some cancers. |
Scorpion toxin that targets 'wasabi receptor' may help solve mystery of chronic pain Posted: 22 Aug 2019 08:34 AM PDT Researchers have discovered a scorpion toxin that targets the 'wasabi receptor,' a chemical-sensing protein found in nerve cells that's responsible for the sinus-jolting sting of wasabi. Because the toxin triggers a pain response, scientists think it can be used as a tool for studying chronic pain and inflammation, and may eventually lead to the development of new kinds of non-opioid pain relievers. |
