| Visuals increase attention; now science explains why Posted: 17 Dec 2021 12:19 PM PST Scientists report that norepinephrine, a fundamental chemical for brain performance, is locally regulated in a brain region called the visual cortex. |
| The origin of neuronal diversity Posted: 16 Dec 2021 12:01 PM PST With a new method researchers can investigate the developmental relationships of cells in the brain. |
| Cannabis may contain heavy metals and affect consumer health, study finds Posted: 16 Dec 2021 12:00 PM PST A new meta-analysis examines the ability of cannabis plants to absorb heavy metals and discusses the resulting health impacts on consumers. |
| Artificial intelligence accurately predicts who will develop dementia in two years Posted: 16 Dec 2021 11:59 AM PST Artificial intelligence can predict which people who attend memory clinics will develop dementia within two years with 92 per cent accuracy, a largescale new study has concluded. Using data from more than 15,300 patients in the US, researchers found that a form of artificial intelligence called machine learning can accurately tell who will go on to develop dementia. |
| Prenatal exposure to phthalates damages reproductive tissue in female mice Posted: 15 Dec 2021 05:41 PM PST Phthalates are a ubiquitous family of chemicals that are used every day. In a new study, researchers have investigated how these compounds affect tissue development in the reproductive systems of female mice offspring. |
| Posted: 15 Dec 2021 05:40 PM PST Researchers developed a new, faster, less expensive method for screening billions of chemical compounds to find new, targeted drug therapies. |
| New discovery on how omega-3 fatty acids can reduce atherosclerosis Posted: 15 Dec 2021 09:49 AM PST A receptor activated by substances formed from omega-3 fatty acids plays a vital role in preventing inflammation in blood vessels and reducing atherosclerosis, a new study reports. The discovery can pave the way for new strategies for treating and preventing cardiovascular disease using omega-3 fatty acids. |
| New study reveals how epithelial cells in the body naturally eliminate 'precancerous' ones Posted: 15 Dec 2021 08:32 AM PST Normal epithelial cells show the ability to push out precancerous ones present in the epithelium, by means of 'cell competition.' But the exact molecular mechanism of this recognition by normal epithelial cells was unknown. Now, researchers have unraveled the interactions and cellular pathways leading to this extrusion, allowing them to identify a candidate for a therapeutic target for future cancer prevention research. |
