| New tool activates deep brain neurons by combining ultrasound, genetics Posted: 28 May 2021 12:05 PM PDT A team has developed a new brain stimulation technique using focused ultrasound that is able to turn specific types of neurons in the brain on and off and precisely control motor activity without surgical device implantation. |
| Waking just one hour earlier cuts depression risk by double digits, study finds Posted: 28 May 2021 08:41 AM PDT A genetic study of 840,000 people found that shifting sleep time earlier by just an hour decreases risk of major depression by 23 percent. |
| Versatile coronavirus antibody may be starting point for broader-acting vaccines Posted: 27 May 2021 05:42 PM PDT Scientists investigated how the immune system's previous exposure to cold-causing coronaviruses impact immune response to COVID-19. In doing so, they discovered one cross-reactive coronavirus antibody that's triggered during a COVID-19 infection. |
| Biologists construct a 'periodic table' for cell nuclei Posted: 27 May 2021 11:52 AM PDT Biologists have created a new classification system for cell nuclei -- and shown how they can be transmuted from one type into another. |
| Electric fish -- and humans -- pause before communicating key points Posted: 26 May 2021 10:21 AM PDT Electric fish pause before sharing something particularly meaningful. Pauses also prime the sensory systems to receive new and important information. The study reveals an underlying mechanism for how pauses allow neurons in the midbrain to recover from stimulation. |
| Understanding of invisible but mighty particles in Earth's radiation belts Posted: 26 May 2021 06:31 AM PDT Tiny charged electrons and protons which can damage satellites and alter the ozone have revealed some of their mysteries to scientists. |
| Memory details fade over time, with only the main gist preserved Posted: 26 May 2021 05:50 AM PDT What information is retained in a memory over time, and which parts get lost? These questions have led to many scientific theories over the years, and now researchers have been able to provide some answers. |
| How to boost muscle regeneration and rebuild tissue Posted: 25 May 2021 08:37 AM PDT In work that could one day help athletes as well as aging adults regenerate tissue more effectively, scientists increased the regeneration of muscle cells in mice by activating the precursors of muscle cells. |
| Dark matter map reveals hidden bridges between galaxies Posted: 25 May 2021 07:17 AM PDT A new map of dark matter in the local universe reveals several previously undiscovered filamentary structures connecting galaxies. The map, developed using machine learning, could enable studies about the nature of dark matter as well as about the history and future of our local universe. |
| Solar geoengineering may be effective in alleviating impacts of global warming on crops Posted: 20 May 2021 10:37 AM PDT A growing body of research has explored the ability of solar geoengineering to reduce physical climate changes. But much less is known about how solar geoengineering could affect the ecosystem and, particularly, agriculture. Now, research finds that solar geoengineering may be surprisingly effective in alleviating some of the worst impacts of global warming on crops. |
