| COVID-19 pandemic linked to an increase in intimate partner aggression, study shows Posted: 17 Aug 2021 04:30 PM PDT Rates of physical and psychological aggression among couples increased significantly after the implementation of shelter-in-place restrictions at the outset of the COVID-19 pandemic, according to a new study. The findings indicate that stress related to the pandemic was strongly associated with perpetration of intimate partner aggression, even among individuals considered at low risk. |
| Use your team’s emotions to boost creativity Posted: 17 Aug 2021 04:30 PM PDT If you're putting together a team for a project, you might be inclined to pick people with cheerful, optimistic dispositions and flexible thinking. But a new management study indicates your team might also benefit from people who are exactly the opposite. |
| How microbes can exacerbate cognitive decline Posted: 17 Aug 2021 10:13 AM PDT Recent research has found that changes in the gut microbiota -- the trillions of bacteria and other microbes that live in the intestines -- can alter the brain and behavior. A new study could elucidate how and why that phenomenon occurs. |
| Genome-editing strategy developed for potential Alzheimer’s disease therapy Posted: 17 Aug 2021 09:15 AM PDT Scientists have developed a novel strategy using brain-wide genome-editing technology that can reduce Alzheimer's disease(AD) pathologies in genetically modified AD mouse models. This advanced technology offers immense potential to be translated as a novel long-acting therapeutic treatment for AD patients. |
| Gender revolutions in who holds the purse strings Posted: 17 Aug 2021 08:14 AM PDT New research has uncovered considerable class differences in the gender revolution of who holds the purse strings among British couples. Low-earning and high-earning women are taking more control of the finances in their relationships, but in different ways, says the research. |
| Histamine could be a key player in depression, according to study in mice Posted: 17 Aug 2021 08:14 AM PDT Bodily inflammation dampens levels of a 'feel-good molecule' and antidepressants' ability to boost them, according to new research in mice. |
| Brain organoids develop optic cups that respond to light Posted: 17 Aug 2021 08:13 AM PDT Human induced pluripotent stem cells (iPSCs) can be used to generate brain organoids containing an eye structure called the optic cup, according to a new study. The organoids spontaneously developed bilaterally symmetric optic cups from the front of the brain-like region, demonstrating the intrinsic self-patterning ability of iPSCs in a highly complex biological process. |
| Mutated enzyme weakens connection between brain cells that help control movement Posted: 17 Aug 2021 05:46 AM PDT In one type of a rare, inherited genetic disorder that affects control of body movement, scientists have found a mutation in an enzyme impairs communication between neurons and what should be the inherent ability to pick up our pace when we need to run, instead of walk, across the street. |
| Blind people can’t see color but understand it the same way as sighted people Posted: 16 Aug 2021 09:57 AM PDT People born blind have never seen that bananas are yellow but researchers find that like any sighted person, they understand two bananas are likely to be the same color and why. Questioning the belief that dates back to philosopher John Locke that people born blind could never truly understand color, the team of cognitive neuroscientists demonstrated that congenitally blind and sighted individuals actually understand it quite similarly. |
| Researchers develop new way to study neurodegenerative diseases Posted: 13 Aug 2021 12:19 PM PDT Some proteins in cells can separate into small droplets like oil droplets in water, but faults in this process may underlie neurodegenerative diseases in the brains of older people. Now, researchers have developed a new method to quantify protein droplets involved in these diseases. |
