Modifying 12 risk factors over a lifetime could delay or prevent 40% of dementia cases, according to an updated report by the Lancet Commission on dementia prevention, intervention and care presented at the Alzheimer’s Association International Conference (AAIC 2020).

Twenty-eight world-leading dementia experts added three new risk factors in the new report — excessive alcohol intake and head injury in mid-life and air pollution in later life...

Two-photon lithography (TPL)—a widely used 3-D nanoprinting technique that uses laser light to create 3-D objects—has shown promise in research applications but has yet to achieve widespread industry acceptance due to limitations on large-scale part production and time-in...

Extensive power outages and satellite blackouts that affect air travel and the internet are some of the potential consequences of massive solar storms. These storms are believed to be caused by the release of enormous amounts of stored magnetic energy due to changes in the magnetic field of the sun’s outer atmosphere — something that until now has eluded scientists’ direct measurement. Researchers believe this recent discovery could lead to better “space weather” forecasts in the future.

“We are becoming increasingly dependent on space-based systems that are sensitive to space weather...

In a pilot study of people living with HIV or high levels of cholesterol, Johns Hopkins Medicine researchers found that a six-week course of a cholesterol-lowering medication improved the function of the coronary arteries that provide oxygen to the heart.

The drug used in the study, a PCSK9 inhibitor, lowers the activity of PCSK9, a protein involved in cholesterol metabolism. These levels are higher in people with HIV and in those with high cholesterol. Currently, people with HIV receive antiretroviral medications and rarely die from the virus itself...
