We hung up this photo on the landing of our staircase and this guy brings me joy every time I climb the stairs. So - I thought I’d share! #happymoray #Aruba

Coffee linked to slower brain ageing in study of 130,000 people Study suggests moderate caffeine intake might reduce dementia risk and slow cognitive decline.

The only science I never question is the one that validates my love for coffee and justifies my daily consumption of the piping hot black brew😊.
I will not be taking any questions.

I believe this. We just posted an ad for a job. Had a similar posting 3 years ago. I’m getting 5-10x more applications. Most applicants currently do not have a job, and most are recent grads. 😩😩😩

And the new NCI Director moves to piss away his scientific credibility.

First, killing cancer cells is a very low bar; many compounds kill cancer cells and are not the least bit useful for treating cancer.

EP here - you’d be surprised how many patients are just discharged home in AF, with only intervention being an OAC, maybe a little metoprolol, and a referral to EP.

FDA Announces Canned Tuna Recall in 9 States Over Botulism Risk Tri-Union Seafoods initiated the recall after a distributor mistakenly shipped quarantined cans, which were first recalled last February.

12 months of MAHA:

Our last foodborne botulism outbreak hasn’t been resolved yet & now one of the only affordable sources of lean protein is a botulism risk, too; measles cases are exploding, even tuberculosis is on the rise. And they’re still trying to deregulate more.

Maybe expertise did matter…

The fact that nothing is being done about this β€” and that people keep blithely hanging out on that site as though its owner and a key part of its official architecture aren’t actively enabling disgusting criminal abuse at scale β€” is making me lose my mind

As if having cancer or an immune deficiency as a kid isn’t bad enough, those patients also can’t receive vaccines.

They rely on herd immunity, others doing the right thing.

It’s the same with infants who are too young to be vaccinated but are also at increased risk of morbidity and mortality.

The White House claims the vote to rename the Kennedy Center was β€œunanimous.” That is false. I was muted on the call and denied the opportunity to speak or register my opposition. That is not consensus. That is censorship.

Just imagining how much better it would be if ALL news stories about vaccine-preventable illnesses were illustrated with pictures of people with the disease, not pictures of needle injections. If you must show something that people will find scary & unpleasant, make it the disease, not the cure.

I think a lot of us learned (the hard way) NOT to engage in the Bad Place. It might take a while to unlearn this behavior. And yeah, no algorithms.
