Neanderthal dad, human mum: study reveals ancient procreation pattern Genomic analysis shows that interbreeding between female Neanderthals and human males was less common than the opposite combination.

Exercise to Improve Migraine: How Much Is Enough? - Migraine Science Collaborative A new meta-analysis posits an aerobic exercise therapeutic window for reducing migraine pain and frequency, though uncertainty remains.

MSC News: A new meta-analysis posits an aerobic exercise therapeutic window for reducing #migraine pain and frequency, though uncertainty remains. Nice work by @fredakreier.bsky.social

The Evidence Builds for an Older, Less Expensive Drug to Treat Migraine - Migraine Science Collaborative The largest trial to date of candesartan, an angiotensin receptor blocker, confirms the efficacy of two different doses to alleviate episodic migraine.

I write a lot about barriers to #migraine care. Personally, there are few things as frustrating as trying to establish care with a neurologist in the U.S. (Yes, I just moved. Yes, I’m trying to get a new doctor. No, it is not going well)

Targeting the Circadian System for Migraine Treatment: A Conversation with Yohannes W. Woldeamanuel - Migraine Science Collaborative In this Migraine Science Collaborative interview, Yohannes Woldeamanuel talks about the hidden complexities of the circadian system and shares his experience on this new migraine research frontier.

🧪 Do migraines respond to our circadian rhythm? And if so, can we use our internal clocks to treat migraine patients? My latest Q&A with Dr Yohannes Woldeamanuel for @migrainecollab.bsky.social digs into this emerging field of study: migrainecollaborative.org/targeting-th...

@johngreensbluesky.bsky.social your writing on chronic illness in Everything Is Tuberculosis brought me to tears. Thank you for writing this book.

The Long Quest to Uncover a Sea Star Killing Bacteria Scientists say they’ve found the cause of a marine epidemic more than 10 years after it started. What took so long?

🧪 We found the cause of COVID-19 in less than a month. So why did it take a decade to (maybe?) find the pathogen behind sea star wasting disease? My latest is a deep-dive for @undark.org into why we’re so bad at identifying the root cause of marine epidemics in invertebrates.

New US Government Policies Hit the Migraine Field - Migraine Science Collaborative Members of the migraine community express uncertainty about how the new directives will play out.

Our most popular article during the first half of this year was our coverage of the potential effects of new US government policies on the #migraine field. Read more on MSC. Nice work by @fredakreier.bsky.social

Check out her latest story for @migrainecollab.bsky.social, which covers a recent clinical trial of an anti-CGRP antibody to treat both migraine AND comorbid depression. #headache #migraine #fremanezumab

New Clinical Trial Results: Anti-CGRP Treatment Improves Migraine and Comorbid Depression - Migraine Science Collaborative The first study of its kind shows that fremanezumab could be an effective drug to manage this common comorbidity of migraine.

🧪 It's not just you: people who take some CGRP antibodies for #migraine are less depressed compared to a placebo group. You know, probably because they have fewer migraines. But maybe because it works on some biological system! My latest for the Migraine Science Collaborative:

🧪 Earlier today I was called out by an anonymous account for only seeking a single source for this story, and they've since written an 800+ word blog post about how bad at my job I am, calling me a "bullshit alleged profession idiot."

🧪I'm looking for studies that explain WHY fruit ripen (and why they suck to eat/are toxic before they are ripe). This is proving surprisingly hard. Are any plant folks out there able to lend a hand?
