| Creating a reference map to explore the electronic device mimicking brain activity Posted: 14 Jan 2022 08:56 AM PST Just like explorers need maps, scientists require guides to better understand and advance new technology. A neuromorphic device, which can mimic the neural cells in our brain, has lacked such a guideline and created headaches for scientists trying to understand their operational mechanisms. That is until now after a research group created a map that provides rational design guidelines for neuromorphic devices, paving the way for advancements in brain-inspired computers. |
| Do we get our most creative ideas when walking? Posted: 14 Jan 2022 08:56 AM PST Do we have our best ideas while walking? Indeed, but even small movements while sitting improve creativity, as two researchers have discovered. |
| Risk of schizophrenia linked to brain cell development Posted: 14 Jan 2022 04:44 AM PST Scientists have discovered new links between the breakdown in brain cell development and the risk of schizophrenia and other psychiatric disorders. |
| Epstein-Barr virus may be leading cause of multiple sclerosis Posted: 13 Jan 2022 12:13 PM PST A new study provides compelling evidence of causality between Epstein-Barr virus and multiple sclerosis. It suggests that most MS cases could be prevented by stopping EBV infection, and that targeting EBV could lead to the discovery of a cure for MS. |
| Mouse study finds age, disease change body temperature rhythms Posted: 13 Jan 2022 12:13 PM PST A new study finds that while young and healthy mice show clear differences between daytime and nighttime body temperature rhythms, in older and diseased animals the difference essentially disappeared. |
| Heart disease causes early brain dysfunction and can treble key Alzheimer’s protein Posted: 13 Jan 2022 09:07 AM PST Heart disease can directly cause brain dysfunction early on which could lead to dementia and can treble the amount of an Alzheimer's protein in the brain, say scientists. |
| Next-generation tissue expansion method improves neural imaging Posted: 13 Jan 2022 09:07 AM PST 'eMAP' enables labeling of more than a dozen more synaptic proteins than its predecessor MAP, allowing for deeper studies of circuit junctions in brain tissue. |
| Scientists dive deep into the different effects of morning and evening exercise Posted: 13 Jan 2022 08:15 AM PST Exercise causes the body to release hundreds of different signals that improve our health in many different ways. Now scientists have mapped these intrinsic signals and how they are released by different organs in mice following exercise at different times of the day. Their 'Atlas of Exercise Metabolism' is a major step toward developing more effective exercise therapies that are timed to the body clock. |
| Green-med diet seems to slow age-related neurodegeneration, study finds Posted: 13 Jan 2022 08:15 AM PST A green Mediterranean diet, high in polyphenols and low in red and processed meat, seems to slow age-related brain atrophy, according to a new study. The DIRECT PLUS 18-month long randomized control trial among approximately 300 participants is one of the longest and largest brain MRI trials in the world. |
| Why do we forget? New theory proposes 'forgetting' is actually a form of learning Posted: 13 Jan 2022 08:14 AM PST We create countless memories as we live our lives but many of these we forget. Why? Counter to the general assumption that memories simply decay with time, 'forgetting' might not be a bad thing -- that is according to scientists who believe it may represent a form of learning. |
| Posted: 13 Jan 2022 06:21 AM PST Patients hospitalized for COVID-19 had higher levels over the short term of blood proteins known to rise with neurological damage than non-COVID-19 patients diagnosed with Alzheimer's disease. |
| Get moving to put the brakes on early Parkinson’s Posted: 12 Jan 2022 03:13 PM PST A new study suggests that people with early-stage Parkinson's disease who regularly got one to two hours of moderate exercise twice a week, like walking or gardening, may have less trouble balancing, walking and doing daily activities later. |
| Removing brain cells linked to wakefulness and addiction may lessen symptoms of opioid withdrawal Posted: 12 Jan 2022 12:49 PM PST A study in mice shows that removing chemical messengers in the brain that are involved in both wakefulness and addiction may make withdrawal from opioids easier and help prevent relapse. |
| Stress associated with an increased risk of getting COVID-19, study finds Posted: 12 Jan 2022 11:51 AM PST A new study has found that people who experienced increased stress, anxiety and depression at the start of the pandemic, were at greater risk of getting COVID-19. The research found that greater psychological distress during the early phase of the pandemic was significantly associated with participants later reporting SARS-CoV-2 infection, a greater number of symptoms and also more severe symptoms. |
| Environment key to injury recovery Posted: 12 Jan 2022 11:50 AM PST Black men are disproportionately impacted by injuries in the United States. This disparity is glaring given that injury is one of the top ten causes of death. Data show that injured Black men from disadvantaged neighborhoods experience higher injury mortality, years of life-expectancy loss, and psychological symptoms that persist after initial wounds have been treated. |
| Posted: 12 Jan 2022 07:56 AM PST Researchers have characterized how spindle detection parameter settings influence the association between spindles and cognition, and they identified parameters that best correlate with cognitive performance. |
| New knowledge about the 'happiness hormone' dopamine Posted: 11 Jan 2022 12:36 PM PST New findings provide a better understanding of how the synthesis of dopamine is regulated in the brain. It may shed new light on the mechanism behind diseases such as Parkinson's. |
| Rare African script offers clues to the evolution of writing Posted: 10 Jan 2022 07:32 AM PST Writing evolves to become simpler and more efficient, according to a new study based on the analysis of an isolated West African writing system. |
| Cannabis poisoning in young children increased nine times after legalization Posted: 07 Jan 2022 09:15 AM PST Ontario saw nine times more emergency department visits per month for cannabis poisonings in young children under the age of 10 after Canada legalized recreational cannabis. While single hospitals have reported on child cannabis poisonings before, this is the first study to look at an entire region. |
