Or, to put it another way, there are no pain receptors in the brain. The migraine may be the way that the brain provides feedback (that would come as pain in the rest of the body) that there is something seriously wrong that needs to be remedied with behavioral modification (say, with sleep).

I think a lot of people have found something similar with their own migraines. This study provides some mechanistic evidence for why sleeping is helping in these cases to relieve the migraine (or, more specifically, what it means about the state of the brain when the migraine happened).

New study on migraine causes: 🧪
"Migraine is actually protective in that way. The pain is protective because it’s telling the person to rest and recover and sleep," says study co-author Maiken Nedergaard, a neuroscientist at the University of Copenhagen.

Meant to tag this with 🧪 for the butterfly lovers. Pink Lady butterflies that were surprisingly found in South America (far from their West-African home) with tattered wings appear to have been blown off their normal course and forced to fly across the Atlantic until finding land.

Did anyone else notice the #Wink Relay on the wall of the hospital room behind the bed in that scene in the new "Beverly Hills Cop: Alex F" on #netflix? Did the people building the sets just happen to have one in a junk pile? Certainly not a real hospital room, right?

Don't let the interview go to your head. You might be the best person they could find on short notice, or they might have targetted you because they want to advance a larger sensationalistic agenda/"hook" of the story that you might not be 100% okay with implicitly endorsing. Be humble. Be careful.

This is certainly a very interesting and worthwhile topic to discuss in such a class! That said, I hope students know that you do not need to be talking to journalists every week to be a successful scientist, and getting interviews should be a happy privilege not be a primary career goal. 🧪

Do you remember the course numbers for your major courses in college? I do. But back then, my dept (Ohio State ECE) course-number digits had meaning: Digit 1: Typical year Digit 2: Topic area (0 circuits, 1 emag, ...) Digit 3: Seq number/unique ID Made it easy to put courses in context.

They address this in the 2020 PNAS article -- the Danovaro et al (2010) is ref 4. "Although it was reported that some loriciferans found in anoxic conditions possess hydrogenosomes (4, 5), genomic data are not yet available for these organisms, and alternative explanations have been proposed (3)."

Is dark energy a cosmological *constant*, as is most consistent with modern cosmological/GR models? New DESI data suggests a dynamic dark energy that might have been a stronger driver of expansion in the past and will be weaker in the future.

"LOVE" the "TTC"? Do you think he just skipped over each "not"? Also, when he says, "BRING BACK TTC!!!", is the "back" referring to the same time as "Make America Great *Again*"? When are we bringing the "TTC" "BACK" from? thehill.com/homenews/473...

Four related topics that I wish undergrad and high-school stats would better prepare students for: 1. Standard deviation 2. Standard error [of the mean] 3. 95% confidence intervals 4. Central Limit Theorem These are things undergrads all think they know but come up way short when they need them.

Are there actually people who want the *SAME* width error bars across every entry in their figure? Are there actually people who want to visualize 5% of their plotted value with an error bar? Are confidence intervals that hard for programmers to grasp?

Across the built-in ways to plot error bars in GSheets & Excel, Excel's "custom" is the only method that makes any sense for a practical use case. How is it still the case that the default way to do error bars in these programs is still broken and useless? What people use these?
