| Supernova's 'fizzled' gamma-ray burst Posted: 26 Jul 2021 11:48 AM PDT On Aug. 26, 2020, NASA's Fermi Gamma-ray Space Telescope detected a pulse of high-energy radiation that had been racing toward Earth for nearly half the present age of the universe. Lasting only about a second, it turned out to be one for the record books -- the shortest gamma-ray burst (GRB) caused by the death of a massive star ever seen. |
| Hubble finds evidence of water vapor at Jupiter's moon Ganymede Posted: 26 Jul 2021 10:21 AM PDT Astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas. Astronomers re-examined Hubble observations from the last two decades to find this evidence of water vapor. |
| Meeting global climate targets will lead to 8 million more energy jobs worldwide by 2050 Posted: 26 Jul 2021 07:21 AM PDT Researchers created a global dataset of job footprints in 50 countries and used a model to investigate how trying to meet the Paris Agreement global climate target of staying well below 2°C would affect energy sector jobs. They found that action to reach said target would increase net jobs by about 8 million by 2050, primarily due to gains in the solar and wind industries. |
| A novel method for the rapid repair of peripheral nerve injuries Posted: 21 Jul 2021 09:07 AM PDT One of the main problems preventing optimal regeneration following peripheral nerve injuries is that axons within severed nerves have difficulty regenerating and reaching their target. This may be attributed in part to misguided axons that sprout in multiple directions, decreasing probability to reach their target organs. A new technique fills a nerve conduit with gel containing physical and chemical components that promote and align axon regrowth. |
