Long Term Data on Particulate Air Pollution and Dementia in a US Population

There is plenty of evidence for particulate air pollution to have a negative effect on long-term health, particularly those derived from Asian populations that are exposed to more coal and wood smoke than tends to be the case in the US and Western Europe. While the relative importance of the […]

Diving Deeper into the Details of Disarrayed Gene Expression in Aged Tissues

It is well known that gene expression becomes disarrayed in cells in old tissues. Mechanisms controlling the structure of nuclear DNA become dysfunctional, and that can unleash all sorts of errant protein production by allowing the machinery of gene expression to reach sections of the genome that are normally folded […]

In a first for “sonogenetics,” researchers control mammalian cells with sound

Salk researchers pinpoint a sound-sensitive mammalian protein that lets them activate brain, heart or other cells with ultrasound. Salk scientists have engineered mammalian cells to be activated using ultrasound. The method, which the team used to activate human cells in a dish and brain cells inside living mice, paves the […]

Cellular rejuvenation therapy safely reverses signs of aging in mice

Salk researchers treated mice with anti-aging regimen beginning in middle age and found no increase in cancer or other health problems later on. Age may be just a number, but it’s a number that often carries unwanted side effects, from brittle bones and weaker muscles to increased risks of cardiovascular […]
