Human history and migration of disease: Tracking spread of young-onset heart arrhythmia across continents

University of Utah Health scientists have documented the spread of a disease gene across continents and over centuries. The genetic mutation causes a heart arrhythmia, known as atrial fibrillation (AF), that manifests in early adulthood and leads to fatigue, stroke, and increased risk of early death. It is important to identify carriers of this genetic legacy, the authors say, since […]

Australia’s first snapshot of families at risk of blindness from rare genetic eye disease

New research has revealed for the first time the number of Australian families affected by genetic mutations that cause the rare genetic eye disease Leber Hereditary Optic Neuropathy (LHON) – and the risk of going blind from the disease. The research, led by Professor David Mackey AO from the Lions Eye Institute and University of Western Australia and Dr. Isabel […]

What type of ultraviolet light is most effective at killing coronavirus?

Scientists have long known that ultraviolet light can kill pathogens on surfaces and in air and water. UV robots are used to disinfect empty hospital rooms, buses and trains; UV bulbs in HVAC systems eliminate pathogens in building air; and UV lamps kill bugs in drinking water. Perhaps you have seen UV wands, UV LEDs and UV air purifiers advertised as silver bullets to […]

High intake of fatty acid in nuts, seeds and plant oils linked to lower risk of death

A high intake of alpha linolenic acid (ALA)—found mainly in nuts, seeds, and plant oils—is associated with a lower risk of death from all causes, and specifically from diseases of the heart and blood vessels, finds a study published by The BMJ today. Higher ALA intake was associated with a slightly higher risk of death from cancer, but the researchers […]

During COVID, majority of newly unemployed adults in NC did not receive Medicaid

Within the first few months of the pandemic, the US unemployment rate skyrocketed from 3.8 percent in February 2020 to 13 percent in April 2020, quickly surpassing total job losses from the entire two years of the Great Recession. Millions of people who were forced out of the workforce lost both income and employer-sponsored health insurance coverage. Medicaid was designed […]

World’s largest study of spatial navigation offers free study platform to researchers

After a successful journey gathering data from 4.3 million participating players, the groundbreaking citizen science app Sea Hero Quest is now available for studies of cognition and spatial navigation. Sea Hero Quest started out in 2016 as a consumer mobile game to help scientists understand navigational abilities across the life course. By building a picture of how navigation ability changes […]

Novel checkpoint molecule of natural killer cell anti-tumor immunity revealed

Currently, immunotherapy is revolutionizing tumor therapy. However, most patients can’t benefit from available immunotherapy strategies due to limited efficacy and safety, especially those with solid tumors. Natural killer cells (NK cells) are cytotoxic innate immune cells that play an important role in immune surveillance against tumors. However, the underlying mechanisms are still poorly understood. Dr. Tian Zhigang’s group from the […]

Photobiomodulation of the brain: Shining light on treating Alzheimer’s and other neuropathological diseases

Photobiomodulation (PBM) offers exciting opportunities for improving the life of patients with a diverse range of brain disorders. In this special collection of articles in the Journal of Alzheimer’s Disease experts review progress using PBM therapy to treat dementia, Alzheimer’s disease, Parkinson’s disease, and other disorders and suggest larger clinical trials should be conducted as soon as possible. Previously referred […]

Activation of immune system oscillates throughout the day, with a peak just before the start of the day: study

Circadian clocks, which regulate most of the physiological processes of living beings over a rhythm of about 24 hours, are one of the most fundamental biological mechanisms. By deciphering the cell migration mechanisms underlying the immune response, scientists from the University of Geneva (UNIGE), in Switzerland, and the Ludwigs-Maximilians University (LMU), in Germany, have shown that the activation of the […]
