Neuropeptide Y neurons surrounding the locus coeruleus inhibit noradrenergic system activity to reduce anxiety Endogenous neuropeptide Y signaling modulates locus coeruleus activity, promoting adaptive responses to stress.

Beyond happy & proud to have our paper on peptidergic neuromodulation of the #LC out!

This is a project that started with naive intentions & silly curiosity, withstood 1 pandemic & 2 lab moves & made us fall in ❤️ with the most beautiful brain regions of all!! 🔵

Why do we need sleep? Oxford researchers find the answer may lie in New study uncovers how a metabolic “overload” in specialised brain cells triggers the need to sleep.

NEW: Sleep isn’t just for the mind – it’s for your brain’s power supply 🧠🔋

Oxford researchers have found that the urge to sleep may be driven by electrical stress building up in the tiny energy generators inside brain cells.

Why the federal government is making climate data disappear Under Trump, climate denial has given way to something even more dangerous: climate erasure.

"This kind of wholesale suppression of an entire field of federally sponsored research, to my knowledge, is historically unprecedented."

Wow. Kenya is planting trees with seed balls covered in charcoal dust to keep animals from eating them, fight climate change, and combat #deforestation.

We have the solutions; implement them. #ActOnClimate.

Mitochondrial origins of the pressure to sleep - Nature Research on Drosophila neurons shows links between the need to sleep and aerobic metabolism, indicating that the pressure to sleep may have a mitochondrial origin.

The Trump Administration Is About to Incinerate 500 Tons of Emergency Food Federal workers warned for months that the high-energy biscuits would go to waste.

How on earth is burning nearly a million dollars' worth of nutritious biscuits meant for starving children even remotely sensible. It doesn't save money, and children will go hungry. The GOP wants these kids to suffer. That seems to be the message.
