Why are living things different from nonliving? In this piece for @quantamagazine.bsky.social I argue that it is because they are purposive and goal-directed: a capacity we can productively characterize as agency. www.quantamagazine.org/is-life-just...

How does blood flow relate to brain activity? We discovered that it reflects two neural populations affected oppositely by arousal. Together, they explain neurovascular coupling in all brain regions and brain states! Out today in Nature: rdcu.be/fdC2A @uclbrainscience.bsky.social
The supply of blood to brain tissue is thought to depend on the overall neural activity in that tissue, and this dependence is thought to differ across brain regions and across brain states. However, studies supporting these views have measured neural activity as a bulk quantity and related it to blood supply following disparate events in different regions. Here we measure fluctuations in neuronal activity and blood volume across the mouse brain, and find that their relationship is consistent across brain states and brain regions but differs in two opposing brainwide neural populations. Functional ultrasound imaging (fUSI) revealed that whisking, a marker of arousal, is associated with brainwide fluctuations in blood volume. Simultaneous fUSI and Neuropixels recordings showed that neurons that increase activity with whisking have distinct haemodynamic response functions compared with those that decrease activity. Their summed contributions predicted blood volume across states.Brainwide Neuropixels recordings revealed that these opposing populations coexist in the entire brain. Their differing contributions to blood volume largely explain the apparent differences in blood volume fluctuations across regions. The mouse brain thus contains two neural populations with opposite relations to brain state and distinct relationships to blood supply, which together account for brainwide fluctuations in blood volume.

Remembering Barbara McClintock on International Women's Day! She discovered that genes aren't static, they can actually "jump" around on a chromosome. Her discovery of transposons ("jumping genes") fundamentally changed how we understand evolution and the complexity of DNA! 🧬🌽 #WomenInScience
A detailed digital composite image based on the 1947 historical photograph of geneticist Barbara McClintock. McClintock, with her characteristic short hair and round glasses, is seated at a microscope, using tweezers in a Petri dish. While based on the original photo distributed for her AAUW award, this image presents a significantly expanded and fictionalized laboratory environment. The simple wooden workbench is now densely populated with a vast, colorized collection of complex glassware, numerous amber-colored reagent bottles, intricate distillation columns, and botanical specimens relevant to maize cytogenetics, creating a rich, illustrative narrative of her "jumping gene" research context that was not present in the original photo. The expanded background shows complex vintage laboratory cabinetry. This image explicitly states it is a composite: a digital recreation where Seriously Scientific has taken the historical figure and placed them into an augmented, complex fictionalized environment. Based on original source from Smithsonian Institution Archives. Digital composite by Seriously Scientific.
