✨ Highlights:
🔹 BIN1 is enriched at inhibitory synapses
🔹 Loss-of-function (shRNA/LOAD mutants) → loss of inhibitory synapses, hyperactivity
🔹 Effects are independent of Aβ
🔹 Levetiracetam rescues function

🧠 What if Alzheimer’s risk starts at the synapse?
In our new study led by Mariana Barata, we show that BIN1, a key AD risk gene, regulates inhibitory synapses—loss of BIN1 → hyperexcitability before Aβ.

Big news: we are setting up a new non-profit organization to run bioRxiv and medRxiv. It's called openRxiv [no it's not a new preprint server; it's dedicated organization to oversee the servers] openrxiv.org 1/n
Pronto.... já nasceu a criança.

If you're in the US, considering Europe for your PhD, and you identify as a minority, I will chat with you and review any application documents you need 🧪
Há quase um ano que os cientistas aguardam pelos resultados das candidaturas ao principal concurso para financiamento de projectos de investigação. Alguns, no entanto, já tiveram resposta.
Obrigada @publico.pt por esta notícia desde Dezembro que os cientistas vivem num estado de ansiedade por causa da FCT, e desde que sairam para alguns a injustiça é imensurável porquê ? www.publico.pt/2025/03/02/c...
Concordando com o acesso a todas as publicações científicas não vejo realmente implementar. O guia diz que posso publicar num jornal open access que tem um custo exorbitante apesar de a política de acesso aberto não permitir o pagamento duplo, pela ciência e pela publicação acessoaberto.fct.pt
My NIH study section that was to meet tomorrow was one of those canceled. This represents many months of work by the applicants and by the NIH staff and reviewers. Devastating is the correct word.

Do it today, and every time one of the broligarchs has a tantrum because he can’t buy it
'The FDA’s Center for Drug Evaluation and Research approved 50 new small molecules, biologics and oligonucleotide therapeutics last year. The class of 2024 was a little smaller than that of 2023, which had 55 approvals and was the second largest in the past 30 years'

Where is the muscle? Arrows 🙏 please
Já começo a duvidar 🤔
Alguém sabe quando saem os resultados dos projetos FCT (PTDC)?
@mcti.bsky.social #FCT
Yes please
Highly-respected non-profit journals like @dev-journal.bsky.social support scientific communities
But after rejection at glam journals, it is tempting to avoid re-review by sliding through commercial ecosystems
BUT WAIT! LOOK! “We will consider papers with reviewer reports from other journals” 😍
Dis you see our last paper in J neurosci? No endosomes only cytoskeleton! It was fun!
Cytoskeleton rules!!!
Excited to share our work @science.org. led by our incredible @tommyz626.bsky.social at @rockefelleruniv.bsky.social! By profiling 21 million single cells across life stages, we reveal aging as distinct, development-like transitions, with dramatic cell population changes in specific time windows!
Send me a message for full-text 🙏
Yes! Our discovery that CD2AP loss of function might increase the risk of Alzheimer’s by disrupting dendritic spines directly via F-actin regulation and indirectly via beta-amyloid production is on the cover #jneurosci www.jneurosci.org/content/44/4...

Apesar do alerta de muitos investigadores com posições de liderança na ciência que se faz neste país o partido socialista absteve-se ao reforço do orçamento que visava não aumentar mas apenas não diminuir face ao ano passado. @ciencia_pt 🧪

Who should you nominate as reviewers for your manuscript? After a long chat with a post-grad it appears that there's a lot of misguided advice out there. Thread 👇
