A study revealed why certain parts of the brain are particularly vulnerable to Alzheimer's damage. It comes down to the gene APOE, the greatest genetic risk factor for Alzheimer's disease. The parts of the brain where APOE is most active are the areas that sustain the most damage, they found
Patients with acute COVID-19 infection have higher amounts of the cytokine IL-26 in their blood, according to researchers at Sweden's Karolinska Institutet. Furthermore, high IL-26 levels are associated with an increased inflammatory response, which indicates severe cases of the disease. The

Some commercial earbuds can perform as well as hearing aids. The result, presented on November 15 in the journal iScience, could help a large proportion of people with hearing loss access more affordable sound amplification devices.
A team of scientists from the Department of Energy's Ames National Laboratory developed a new characterization tool that allowed them to gain unique insight into a possible alternative material for solar cells. Under the leadership of Jigang Wang, senior scientist from Ames Lab, the team dev
Exposure to artificial LAN at night is a ubiquitous environmental risk factor in modern societies. The intensity of urban light pollution has increased to the point that it not only affects residents of big cities, but also those in distant areas such as suburbs and forest parks that may be
Researchers have identified that people who inherit a faulty copy of the BRCA1 gene may develop mutations and cancer due to error-prone DNA replication and repair. When these individuals' cells are under stress, replication of the normal BRCA1 gene stalls because of the highly repetitive DNA
Researchers have discovered that parasites associated with leprosy can reprogramme cells to increase the size of a liver in adult animals without causing damage, scarring or tumors.
Evidence suggests that one's sense of purpose, the degree to which someone perceives a sense of direction and goals in their life, might be linked to health-protective benefits such as improved physical functioning and lower risks of cardiovascular disease or cognitive decline.
