Did adaptation to lead exposure give our ancestors an evolutionary edge? 🤯
A study found early humans had genetic protection against lead's neurological damage, which Neanderthals lacked. This might have protected speech and language abilities.

Lead is often thought of as a modern toxin, but a new study has found that it's been haunting us and our ancestors for almost 2 million years.

I'm not a fan or opponent of plant-based meat alternatives (although I ate a lot of them when I was vegetarian)... but this just seems like performative BS.
People are smart enough to know that a veggie burger pattie doesn't contain meat, and PB versions of burgers and sausages have been around for as long as I can remember. 🤷🏽‍♂️

I'm appalled & saddened by swelling antisemitism & attacks on Jewish people post-Oct 7.
https://www.bbc.com/news/articles/c4g9ydq8799o
Separate outrage at Hamas & the Israeli Gov. from those people who happen to be of the same religions.
We can oppose genocide without defaulting to antisemitism.

People are told not to attend A&E units in the region unless it's urgent after the fatal stabbings.

Are you worried about the role of Paracetamol in autism?

There was rationale to explore the association between paracetamol and autism spectrum conditions, as early research showed an association between natal paracetamol use and ASC, albeit small.
However, more recent analyses (including sibling control analysis) exploring in greater depth study quality and confounding influences, find no association between paracetamol and ASC.

So, when confounding influences are corrected for, there does not appear to be any association between paracetamol use and autism.
