So so sooo cool!! 🤯 My jaw was on the floor when Nachum talked about this at FENS 2024. Unique and important work, and a far cry from the standard lab-based openfield (I'm not jealous at all, definitely not...☀️)

Two of Israel’s best-known human rights groups said Monday that Israel was committing genocide against Palestinians in Gaza, adding fuel to an international debate over whether the death and destruction there have crossed a moral red line.

In a First, Leading Israeli Rights Groups Accuse Israel of Gaza Genocide

Israel says it is fighting against Hamas, not Palestinians as a group. But two of Israel’s best-known rights groups — long critical of Israeli policy — now say they disagree.

I’m thinking today about all the women doing DEI work in universities, and how all of our canceled grants and shuttered initiatives means that not only are we losing the time we’ve already put in, we’re now even more behind our male peers who stayed focused on their research.

I’m excited to share my final co-first author paper from my postdoc in Dan Dombeck's lab!

We explored how behavior, senses, and neurons influence how much information in the brain changes over time.

Hippocampal representations drift in stable multisensory environments - Nature

Tracking of individual place cells in mouse CA1 shows that representational drift is not influenced by changes in environment or behaviour, and is lower for more excitable place cells.

NEW: In an unprecedented move, the NIH will soon disinvite dozens of scientists about to take positions on advisory councils that make final decisions on grant funding.

NIH staff were told to select others aligned with the Trump administration and told to expect placements by political appointees.

Exclusive: NIH to dismiss dozens of grant reviewers to align with Trump priorities

The move would undo years of work, leaving advisory councils understaffed, and without the full expertise needed for reviews.

Wow, look at this: the carbon intensity of UK electricity is currently only 32g/kWh and 86.5% of our electricity right now is coming from renewables.

Come on world, this IS possible!
And it will only get better (meaning: cleaner, healthier, less intrusive) 🎉
