Neuroscientists found that higher levels of the alpha-synuclein protein in the brain can lead to changes in vocal production.

Patients diagnosed with cancer more than one year ago and those not receiving active treatment were no more vulnerable to worse COVID-19 outcomes than patients without cancer, according to a new study.

A new device uses millimeter-wave imaging -- the same technology used in airport security scanners -- to scan a patient's skin to detect if they have skin cancer. Millimeter-wave rays harmlessly penetrate about 2mm into human skin, so the team's imaging technology provides a clear 3D map of scanned skin lesions.
Bye, bye, biopsy? Handheld device could painlessly identify skin cancers

Should people undergo regular checks for skin cancer, particularly the deadliest form, melanoma? That depends on who you ask. In its most recent recommendations, an influential federal health advisory panel said there isn’t enough evidence to recommend for or against routine skin cancer screening. But professional dermatology organizations and skin cancer advocacy groups aren’t necessarily on the same page, with at least one recommending that adults have annual skin checks.

Online resources, such as websites and social media sites, should make it easy for you to learn who is responsible for the site and its information (see Question 1). If the person or organization in charge of a website did not write the material, the website should clearly identify the original source of the information. For social media sites, it is also important to consider whether the source of the posted content is reliable (see Question 4). Health-related websites should give information about the medical credentials of the people who have prepared or reviewed the material on the site (see Question 6). Any site that asks you for personal information should explain exactly what the site will and will not do with that information (see Question 9). The U.S. Food and Drug Administration and Federal Trade Commission are federal government agencies that help protect consumers from false or misleading health claims on the internet (see Question 12).

In a new study, researchers used principal component analysis along with fluid dynamics simulation models to show the crucial importance of proper fit for all types of masks and how face shape influences the most ideal fit. They modeled a moderate cough jet from a mouth of an adult male wearing a cloth mask over the nose and mouth with elastic bands wrapped around the ears and calculated the maximum volume flow rates through the front of mask and peripheral gaps at different material porosity levels.

Elevated levels of an enzyme called PHGDH in the blood of older adults could be an early warning sign of Alzheimer's disease. Researchers have consistently found high levels of PHGDH expression in brain tissue and blood samples of older adults with different stages of the disease.

Blood levels of a protein called NfL could help identify people with a brain disease called frontotemporal dementia, or FTD, even in its early stages. Having a biomarker to help detect and track FTD may help researchers in developing new treatments, which will likely work best when used early.
Blood marker shows potential for tracking frontotemporal dementia

Seven hours is the ideal amount of sleep for people in their middle age and upwards, with too little or too much little sleep associated with poorer cognitive performance and mental health, say researchers.
