One thing I will always give MDPI is that they don't hide what they are. They're fee-for-service publishers and that's it. I don't like, but it's more honest than the "real" publishing houses, who exploit scientists and turn outrageous profits, all while positioning themselves as "the good ones."
New from The Strain Team:
🎊 Springer Nature Discovers MDPI 🎊
Springer Nature has spawned a copycat journal series called "Discover" mimicking #MDPI journal titles and citation behaviours. We even made a browser game to prove it (see 🔗).

@samkrimmelneuro.bsky.social shows the utility of Precision Functional Mapping deep into the brainstem! The red nucleus turns out to be much more potentially interesting for cognitive neuroscience than anyone thought, including connectivity to the Somato-Cognitive Action Network.
It's shocking how little is known about the brainstem red nucleus. In our new paper “The human brainstem’s red nucleus was upgraded to support goal-directed action” out now in @naturecomms.bsky.social we show that current thinking on the red nucleus is in need of a serious upgrade. rdcu.be/ehbOy

It's not a bad idea to go to the local Walmart or big box retailer and buy lots of consumables now. From toothpaste to soap, anything you can find storage space for, buy before they have to replenish inventory.
Even if it's made in the USA , they will jack up the price and blame it on tariffs.

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back.
This was the largest political gathering in Denver since Obama in 2008.
Also bigger than the 2024 DNC.
And the largest ever rally in Bernie’s career (and obviously, mine too).
