🧵 1/3 I'm excited to share my first first-author paper, just out last week in Neurology! We looked at how parity interacts with Alzheimer's pathology in cognitively healthy postmenopausal women from the ALFA+ cohort in two visits spaced by 3 years. www.neurology.org/doi/10.1212/...

Effect of Parity and β-Amyloid on Cognition and Hippocampal Volume in Postmenopausal Women | Neurology

Background and ObjectivesEpidemiologic studies exploring the effect of parity on Alzheimer disease (AD) yield mixed results, and little is known about how parity may modify the impact of AD pathology ...

Did you know? The neurotransmitter glutamate is implicated in memory, schizophrenia, and depression. However, how it works comes largely from male research. Female subjects must be included in future studies to see how it functions in both sexes, leading to better treatments. #ossd #sabv

Sex differences in AMPA receptor trafficking proteins - Biology of Sex Differences

AMPA receptors are a type of ionotropic glutamate receptor that is important for fast excitatory neurotransmission. healthy brain function. Glutamate signaling is regulated, in part, by the traffickin...

A Comment article published in Communications Psychology argues that the rush to study AI is producing a feedback loop of topical and methodological convergence, flattening scientific imagination and crowding out the pluralism needed to keep research adaptive. 🧪 #ArtificialIntelligence

AI is turning research into a scientific monoculture - Communications Psychology

The rush to study generative AI is producing a feedback loop of topical and methodological convergence, flattening scientific imagination and crowding out the pluralism needed to keep research adaptive, resilient, and intellectually generative.

🧠 Resting-state fMRI is often treated as the gold standard for studying the brain’s intrinsic organization. But is it actually the best way to estimate functional architecture? We tested this directly. 🧵1/8

We're thrilled to announce the Ctrl-Z Award, a US$2,500 prize for researchers “who discover substantial errors in their published work and take meaningful steps to correct the scientific record." Covered by @nature.com today; read more here: centerforscientificintegrity.org/2026/03/10/a...

Keep calm and be transparent: advice from scientists who retracted their papers

Retractions correct the scientific record, but they have stigma attached to them. Some in the research community want that to change.

If you can substitute "hungry ghost trapped in a jar" for "AI" in a sentence it's probably a valid use case for LLMs. Take "I have a bunch of hungry ghosts in jars, they mainly write SQL queries for me". Sure. Reasonable use case. "My girlfriend is a hungry ghost I trapped in a jar"? No. Deranged.

New preprint! tinyurl.com/y6z57dsm How do people discover an effective strategy when the environment shifts—say, when adapting to an unfamiliar trackpad? Our take: strategic motor adaptation isn’t a smooth process of error reduction but rather a process of hypothesis testing. 🧵

Hypothesis Testing Governs an Efficiency-Flexibility Trade-off in Strategic Motor Learning

It remains unknown how people discover an effective movement strategy when the environment changes (e.g., when adapting to a new computer trackpad). We propose that strategic adaptation operates throu...

An M.I.T. study found that 95% of companies that had invested in A.I. tools were seeing zero return. It jibes with the emerging idea that generative A.I., “in its current incarnation, simply isn’t all it’s been cracked up to be,” johncassidysays.bsky.social writes.

The A.I.-Profits Drought and the Lessons of History

Like the steam engine, electricity, and computers, generative artificial intelligence could take longer than expected to transform the economy.
