Our new paper out this week shows that antibodies don’t just get better at what they already recognize—turns out they can learn something entirely new.

This expands how we think about the adaptive immune system’s creative potential.

This is barbaric.

It has been more than 60 days since Israel ordered a halt to all humanitarian aid entering Gaza — no food, fuel or even medicine.

91% of the population analyzed by the UN is estimated to be facing “food insecurity,” with most enduring “emergency” or “catastrophic” levels.

The effect of Israel’s total siege has become “catastrophic,” doctors say. Food, water and medicine shortages are prompting a surge of preventable illnesses, and deaths.

The law determines what is legal. It does not determine what is true; what is just; what is morally and ethically sound and defensible. The history of law is the history of the legal system being wrong on these grounds.

Trans women are women.

Apart from anything else there simply isn't a cast-iron definition of "biological sex" and attempting to make one in the way some of these goons want to effectively amounts to an exhaustive checklist against which any mismatch means you are male, which effectively makes male the human default

Cass report - Sex Matters etc consulted, trans participation refused.
FWS Supreme Court case - Sex Matters etc consulted, trans participation refused.
Puberty blocker ban - Sex Matters etc consulted, trans input ignored.

That should be everything you need to know.

To so many people who think they're "neutral" on this, this is all abstract theoretical argument - this isn't about the trans or lesbian communities that actually exist, it's about hypothetical ones straight people have made up in their minds. Actual lesbian views of trans folks are very different.

All this money & energy spent to make life more miserable for trans people could've been used to fight against domestic violence, wage disparity, sexual harassment, harassment of people accessing abortion services, proper childcare provision; you know, to make the world a better place instead.

An important reminder as the Supreme Court makes its judgement - not a single trans person was heard from at any point during this case before them, even a trans judge who applied was refused.

This is, as usual, the British state acting as cis people to impose their will on trans people.

Essential reading on today's regressive ruling. It's worse than I thought; giving scope for trans women (and men) to be exluded from anywhere that decides it is single sex.

Defining who a lesbian can be is fucking outrageous as well...

When our own universities offer free subscriptions to Copilot, when "AI" is being hyped in every single field, students are bound to fall for the bullshit.
Painfully ironic that the critical thinking skills they need to see through the hype can only come from reading/thinking on their own.
Because some students think they can generate their essay at click of a button or with a voice prompt means, I think, a more insidious and longer term devaluing of learning spaces like the seminar. Why go? Why participate? Why even read? This is an attitude that needs careful attention. And fast.

This is, in large part, pandemic revenge.

As far as these oligarchs are concerned, all science does is tell them stuff they cannot do.

They can't keep spewing carbon.

They can't keep businesses open as usual when millions are dying.

They have concluded that research is the enemy of profit.
