Elevated serum #B12 can be a sign of B12 deficiency! Pseudo-hypercobalaminaemia occurs because circulating B12 is bound to inactive proteins or immune complexes (e.g. macro-B12), leaving intracellular delivery via transcobalamin impaired, so functional deficiency persists despite high total B12. This matters because clinicians may falsely reassure themselves, missing deficiency & underlying disease while neuropsychiatric symptoms continue. In our preliminary UK survey of 46 GPs examining responses to raised B12, not a single respondent identified pseudo-hypercobalaminaemia, revealing a major blind spot in clinical reasoning. Survey was led by Hamza Mahmood @FrimleyHealth & co-supervised by @dr_pratimasingh @HPFT_NHS Read it in full here: cureus.com/articles/44530… #openaccess @neuropsych_ucl @uclh @UCLIoN

What's the coolest science paper of 2025 so far?







We successfully completed both P8 and P9 this weekend, our first time performing two surgeries in one day. Both participants are recovering well and in great spirits. We are looking forward to supporting them on their Neuralink journey.


Very cool paper. “Longer wavelengths in sunlight pass through the human body and have a systemic impact which improves vision” I have known the senior author Glen Jeffery since the mid 90s and he’s always done very interesting work. Another beauty here. nature.com/articles/s4159…






Our paper on the effect of herpes zoster vaccination on dementia is now out in Nature! 🎉 Huge thanks to Felix Michalik, Seunghun Chung, @PGeldsetzer1, and especially Min Xie (@mx_sci) & Simon Heß(@simonhhess) for making the analysis so much fun! 🔗 nature.com/articles/s4158…
