| Understanding learning by inference Posted: 16 Jun 2022 12:25 PM PDT Both humans and other animals are good at learning by inference, using information we do have to figure out things we cannot observe directly. New research shows how our brains achieve this by constructing cognitive maps. |
| Biochemistry researchers repair and regenerate heart muscle cells Posted: 16 Jun 2022 11:27 AM PDT Researchers are reporting new technology that not only repairs heart muscle cells in mice but also regenerates them following a heart attack, or myocardial infarction as its medically known. |
| Computer tool can track stroke rehabilitation to boost recovery Posted: 16 Jun 2022 11:27 AM PDT A sensor-equipped computer program can accurately identify and count arm movements in people undergoing stroke rehabilitation, a new study shows. |
| Repeated hurricane exposure linked to adverse psychological symptoms Posted: 16 Jun 2022 10:52 AM PDT Repeated exposure to hurricanes, whether direct, indirect or media-based, is linked to adverse psychological symptoms and may be associated with increased mental health problems, according to a new study. |
| Posted: 16 Jun 2022 10:52 AM PDT Humans tend to form groups, which often find themselves in conflict with rival groups. But why do people show such a ready tendency to harm people in opposing groups? A new study led by researchers at Virginia Commonwealth University used functional brain imaging technology to reveal a potential answer: It increases activity in the brain's reward network. |
| Shedding light on linguistic diversity and its evolution Posted: 16 Jun 2022 09:16 AM PDT Scholars have created a new global repository of linguistic data. The project is designed to facilitate new insights into the evolution of words and sounds of the languages spoken across the world today. The Lexibank database contains standardized lexical data for more than 2000 languages. It is the most extensive publicly available collection compiled so far. |
| Tight budgeters beware: Skip the coffee before shopping Posted: 16 Jun 2022 09:16 AM PDT The study found that shoppers who drank a cup of complimentary caffeinated coffee prior to roaming the stores spent about 50 percent more money and bought nearly 30 percent more items than shoppers who drank decaf or water. |
| 30-year study links childhood obesity and fitness to midlife cognition Posted: 16 Jun 2022 09:15 AM PDT A new study of the impact of childhood fitness and obesity on cognition in middle age, followed over 1200 people who were children in 1985 for over 30 years, has found that better performance on physical tests is related to better cognition later in life and may protect against dementia in later years. Importantly these findings are not impacted by academic ability and socioeconomic status at childhood, or by smoking and alcohol consumption at midlife. |
| Who wants to be a billionaire? Most don't -- which is good news for the planet Posted: 16 Jun 2022 09:15 AM PDT A new study busts the long-held economic belief that humans are all motivated to want more and more, which could have important implications for sustainability policies. |
| How the cerebellum modulates our ability to socialize Posted: 16 Jun 2022 09:15 AM PDT The cerebellum is essential for sensorimotor control but also contributes to higher cognitive functions including social behaviors. Researchers uncovered how dopamine in the cerebellum modulates social behaviors via its action on D2 receptors (D2R). These new findings pave the way to determine whether socially related psychiatric disorders are also associated with altered dopamine receptors expression in specific cerebellar cell types. |
| Losing a grandmother may trigger rise in depression for some of her survivors Posted: 15 Jun 2022 08:32 AM PDT New research found that for up to seven years after the death of their grandmother, adolescent boys had a 50% increase in depression symptoms compared to peers who were not grieving. Additionally, this loss also was associated with a higher chance of both adolescent boys' and girls' mothers also becoming depressed. |
| Ageism and health: Study shows close links Posted: 15 Jun 2022 08:32 AM PDT Older adults who have worse physical health or mental health, and those with more chronic conditions, are more likely to have experienced many forms of ageism. |
| Novel membraneless organelle could play a role in Alzheimer's treatment Posted: 14 Jun 2022 06:56 AM PDT Neuroscientists have discovered a novel organelle -- a previously unknown cell structure whose function it is to help clean up faulty proteins in times of stress and keep cells functioning in top condition. Optimizing this membraneless organelle, which they call a BAG2 condensate, could lead to treatments for conditions that are the result of misfolded proteins, including Alzheimer's disease, Parkinson's disease and other neurodegenerative conditions. |
| Staring at yourself during virtual chats may worsen your mood Posted: 13 Jun 2022 11:32 AM PDT A new study finds that the more a person stares at themself while talking with a partner in an online chat, the more their mood degrades over the course of the conversation. Alcohol use appears to worsen the problem, the researchers found. |
