MRI method maps blood flows in reverse for deeper insight into brain physiology
The venous system maintains the health of our brains by removing deoxygenated blood and other waste products, but its complexity and variability have made scientific study difficult. Now, a UC Berkeley-led team of researchers has developed an innovative MRI technique that may expand our understanding of this critical system.

Hi friends!
I set my alarm to 5am and headed out for a nice walk. It was getting warm, so I started early. - and it was just so good to do so!
A nice 6h walk with lots of views, lots of photos and just enjoying being out. End the #summit just for me 😍
On the way up I noted all places where I could refuel later using my water filter. Seriously: why didn't I buy that waaays ear…

excellent analysis of covid state of play
From Julia Doubleday.
"Each time a new wave crops up, the media scrambles to let the public know that COVID is spreading “again” ... But each time, it fails to inform the public that nearly half of COVID cases are asymptomatic, that COVID looks different in different patients, that vaccines do not prevent infections, that rapid tests have high false negative rates, and that COVID is fully airborne.
"Taken together, the virus I’m describing is much more difficult to control than the one the press presents. The press frames the virus as something that can be halted by familiarizing yourself with the symptoms, staying home once you feel sick and test positive, and avoided altogether by simply getting vaccinated or keeping ones’ distance from sick people. ...
"The misinformation that reigns in liberal spaces is not the result of accidental miscommunication. People don’t know that the virus is asymptomatic 40% of the time because there is simply no universe where that virus is controllable without an elimination strategy, or a day-to-day mitigation strategy."

Good morning from Harlem
#Photography #GoodMorjjning #Sunrise #NYC

Looking through an arched window two hours after sunrise the hazy sky fades diagonally from light peach at the horizon to baby blue up above. Pointed roofs of Harlem brownstones are silhouetted across the street, and a taller apartment building can be seen in the distance. The green tops of two trees are on the bottom and right.
