| How the brain encodes landmarks that help us navigate
Posted: 10 Mar 2020 07:13 AM PDT  When we move through the streets of our neighborhood, we often use familiar landmarks to help us navigate. And as we think to ourselves, “OK, now make a left at the coffee shop,” a part of the brain called the retrosplenial cortex (RSC) lights up. While many studies have linked this brain region with landmark-based […] |
| Your brain picks viral video winners without you knowing it
Posted: 10 Mar 2020 07:09 AM PDT  When Stanford University neuroscientist Brian Knutson tracked his smartphone usage, he was shocked to learn that he spent twice as much time on his phone as he had anticipated. “In many of our lives, every day, there is often a gap between what we actually do and what we intend to do,” said Knutson, who is a […] |
| Coronavirus symptoms start about five days after exposure
Posted: 10 Mar 2020 07:04 AM PDT  The median incubation period of COVID-19 from exposure to the onset of symptoms is 5.1 days, researchers say, meaning the recommended 14-day quarantine period is a reasonable amount of time to monitor individuals for development of the disease A new study led by researchers at Johns Hopkins Bloomberg School of Public Health suggests that the median […] |
| Docking, rendezvous and Newton’s third law – the challenge of servicing satellites in space
Posted: 10 Mar 2020 07:00 AM PDT  by Jonathan O’Callaghan If you want to build or fix something in space, you might think you’d need a human to do it. But what if you didn’t? What if robotic spacecraft could be used to refuel satellites in orbit, add new instruments to outdated machinery and even build entire structures while in space? This idea […] |
| Simple method to prevent HIV in South Africa and Uganda works
Posted: 10 Mar 2020 06:58 AM PDT  In parts of Africa, where the rate of HIV is high, researchers found that using mobile vans to dispense antiretroviral treatment and other care greatly increased viral suppression. Researchers enrolled 1,315 people living with HIV and not on antiretroviral treatment in a nearly three-year study in South Africa and Uganda using mobile vans to dispense […] |
| Middle class could suffer from tax incentives for businesses
Posted: 10 Mar 2020 06:55 AM PDT  A corporation announces it’s seeking bids from local governments to build a new warehouse or move its headquarters. Policymakers tend to swoop in with this mindset: Let’s entice that company with tax breaks to set up shop here. It’ll create new jobs and enhance the overall health of our economy. But economic development incentives may […] |
| Munich scientists use immune cells against Alzheimer’s
Posted: 10 Mar 2020 06:52 AM PDT  Scientists at the German Center for Neurodegenerative Diseases (DZNE), the Ludwig-Maximilians-Universität (LMU) Munich and Denali Therapeutics (South San Francisco, CA) have developed an approach to stimulate immune cells of the brain in such a way that they might possibly provide better protection against Alzheimer’s disease. Their report has been published in the journal “EMBO Molecular Medicine”. These […] |
| Squatting and kneeling may be better for your health than sitting
Posted: 09 Mar 2020 04:18 PM PDT  Standing desks are so passé. It’s time for squatting desks. A USC-led study shows that squatting and kneeling may be important resting positions in human evolution — and even for modern human health. Sitting for hours a day is linked to some health risks, including cardiovascular disease, likely because it involves low muscle activity and […] |
