Reply to comment by RevolutionaryCoyote in Road Noise Makes Your Blood Pressure Rise – Literally | Study shows the sound of traffic is associated with increased risk of hypertension, calls for public health measures to reduce noise exposure by Hrmbee

Sure, but I don’t hear any road noise from my apartment except for the odd motorcyclist or car tearing down the street at full throttle, and it’s definitely not the tyres that I’m hearing.

So yep, quieter tyres are great, but EVs’ lack of an obnoxiously and unnecessarily loud exhaust is definitely a big bonus, too.

Reply to Depressed, and Aging Fast. People with higher levels of aging-associated proteins were more likely to have high blood pressure, and multiple medical problems. The accelerated aging was also associated with worse performance on tests of brain health such as working memory and other cognitive skills. by Wagamaga

Older adults with depression are actually aging faster than their peers, UConn Center on Aging researchers report.

“These patients show evidence of accelerated biological aging, and poor physical and brain health,” which are the main drivers of this association, says Breno Diniz, a UConn School of Medicine geriatric psychiatrist and author of the study, which appears in Nature Mental Health on March 22.

Diniz and colleagues from several other institutions looked at 426 people with late-in-life depression. They measured the levels of proteins associated with aging in each person’s blood. When a cell gets old, it begins to function differently, less efficiently, than a “young” cell. It often produces proteins that promote inflammation or other unhealthy conditions, and those proteins can be measured in the blood. Diniz and the other researchers compared the levels of these proteins with measures of the participants’ physical health, medical problems, brain function, and the severity of their depression.

To their surprise, the severity of a person’s depression seemed unrelated to their level of accelerated aging. However, they did find that accelerated aging was associated with worse cardiovascular health overall. People with higher levels of aging-associated proteins were more likely to have high blood pressure, high cholesterol, and multiple medical problems. The accelerated aging was also associated with worse performance on tests of brain health such as working memory and other cognitive skills.

Reply to comment by TurningTwo in The largest recorded earthquake in Alberta's history was not a natural event, but most likely caused by disposal of oilsands wastewater, new research has concluded. by GeoGeoGeoGeo

Michigan had a couple earthquakes pretty close together back around 2012. I was led to believe it was because of fracking pumping water deep underground. Having lived there my whole life, and no one from there ever experiencing one prior, this was the most probable cause.
