A small primer on the #NobelPrize awarded to Mary E. Brunkow, Fred Ramsdell and Shimon Sakaguchi today. This prize was for combining two separate fields of immunology research - genetic research on IPEX and immunology research of regulatory T cells (#Tregs), with enormous impact on biology/medicine

How do parietal & premotor areas in the brain adapt to a #BrainComputerInterface? This study shows that frontal & parietal #brain areas co-adapt during BCI-based #MotorLearning, offering insights into visuomotor adaptation & informing future #BCI developments @plosbiology.org 🧪 plos.io/3VEZidV
Left: Schematic representation of the 3D VR setup allowing control of movements through manual control (MC) and brain–computer interface (BCI). The setup includes four infrared cameras for online tracking of hand position using reflective markers, enabling realistic 3D movements and decoder calibration for the BCI task. The monkey’s other arm was gently restrained, and gaze position was monitored using an infrared eye tracker. Right: Averaged 3D trajectories obtained from one experimental session in Monkey Y during 3D reaches performed under the BCI condition.

Randomized controlled trials are a key tool to study cause and effect. Why do they matter and how do they work?

Yet another example that one should not trust AI to summarize scientific articles. While the article mentions a longitudinal study, the paper is purely about cross-sectional data (some of it form longitudinal studies but still...)

Honestly, how do you do a force-field adaptation in your kitchen? 😜

Repeated head impacts in young athletes can cause neuron loss and inflammation long before signs of neurodegenerative diseases appear. Findings may help explain early symptoms in individuals exposed to contact sports and guide efforts to detect and treat brain damage.

Repeated head trauma causes neuron loss and inflammation in young athletes - Nature
Repetitive head impacts from contact sports are associated with brain inflammation, vascular damage and neuron loss that are independent of hyperphosphorylated tau pathology.

I can't do that but that's OK. I block my calendar when I need to write. Take control of your calendar and it will be fine (sorry, unsolicited advice as well ;-) )

The cerebellum isn’t just about coordinating movement. It’s implicated in nearly every domain of cognition—from language to social behavior.

But how exactly does the cerebellum contribute to action and cognition? 🧵

Cerebellar Contributions to Action and Cognition: Prediction, Timescale, and Continuity
The cerebellum is implicated in nearly every domain of human cognition, yet our understanding of how this subcortical structure contributes to cognition remains elusive. Efforts on this front have ten...

We have indeed known for a very long time that optimality does not hold in many circumstances

Interesting to see how the eLife review process shaped this controversial study. The current summary is worth a read! 🧪

Evidence for deliberate burial of the dead by Homo naledi

The authors study the context of the skeletal remains of three individuals and associated sediment samples to conclude that the hominin species Homo naledi intentionally buried their dead. Demonstration of the earliest known instance of intentional funerary practice – with a relatively small-brained hominin engaging in a highly complex behavior that has otherwise been observed from Homo sapiens and Homo neanderthalensis – would represent a landmark finding. The authors have revised their manuscript extensively in light of the reviews of their initial submission, with improved illustration, context, discussion, and theoretical frameworks, leading to an improved case supporting their conclusion that Homo naledi intentionally buried their dead. One of the reviewers concludes that the findings convincingly demonstrate intentional burial practices, while another considers evidence for such an unambiguous conclusion to be incomplete given a lack of definitive knowledge around how the hominins got into the chamber. We look forward to seeing the continued development and assessment of this hypothesis. It is worth noting that the detailed reviews (both rounds) and comprehensive author response are commendable and consequential parts of the scientific record of this study. The editors note that the authors' response repeatedly invokes precedent from previous publications to help justify the conclusions in this paper. While doing so is helpful, the editors also note that scientific norms and knowledge are constantly evolving, and that any study has to rest on its own scientific merit.

Life as an academic is sometimes tough but getting positive reviews for two papers (although one rejection) and one grant in the last days feels very good.
