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.

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.
