Academia feels like walking through the dark with a flashlight-
you become an expert in whatever small patch you illuminate,
then step forward and realize how much you still can’t see.

How come every protagonist of a modern show set in current times has an unbelievable amount of wealth for their circumstance? It’s giving bourgeoisie propaganda.

In situ muscle pre-activation shifts the lateral gastrocnemius muscle–tendon unit to rely on active fascicle lengthening to absorb peak power input Summary: A muscle pre-activation strategy during in situ stretch experiments reveals how a muscle–tendon unit deals with high rates of energy-absorbing demands.

New research by Daisey Vega and IMSI affiliate Christopher J. Arellano in the Journal of Experimental Biology @jexpbiol.bsky.social examines how muscle pre-activation shapes lateral gastrocnemius mechanics during locomotion.

Fall risk-aware adaptation explains suboptimal locomotor performance Human locomotion requires balancing multiple biological objectives, such as metabolic energy efficiency, stability, and symmetry. While models based on optimization successfully predict how humans walk in familiar settings, they fail to explain why individuals adopt inefficient movement patterns in novel environments, even after extensive practice. Here, we show that such suboptimality in a novel environment arises from a fundamental prioritization of safety. We find that individuals do not simply fail to reach an optimal solution; instead, they navigate an environment-dependent risk landscape by mitigating the statistical probability of falling. We find that this risk-averse strategy is explained by adjusting internal learning parameters: specifically, the learning rate and the tradeoff between metabolic cost and symmetry, in a manner that lowers fall risk. To quantify this process, we developed an ‘inverse adaptation’ modeling framework; this approach works backwards from locomotor performance data to mathematically infer the underlying internal learning parameters and how they vary with fall risk. Our analysis reveals that the observed motor performance is explained by a global probabilistic fall risk rather than a local step-based measure of instability. Ultimately, these findings reveal that fall risk-aware adaptation explains suboptimal locomotor behavior, providing a new data-driven framework to understand the drivers of motor performance. ### Competing Interest Statement The authors have declared no competing interest.

How does perceived risk shape adaptation and learning?

Our new work reveals that locomotor adaptation proactively navigates a "fall risk landscape" , modulating learning parameters that dictate optimality to prioritize safety.

Migratory bird stopover patterns linked to urbanization and social landscapes - Nature Cities Urban ecology traditionally focuses on single cities, yet cities play key roles in ecological processes such as migration. Radar analysis across the continental USA reveals that nearly half of stopove...

A study I led came out in Nature Cities yesterday!

We used radar to study the role that urban landscapes play in migratory bird stopover. Spoiler: birds use cities a lot, and the patterns of their use reflect social processes and the inequities embedded in them.

Posted some photos of a man trying to break into my house a few nights ago on NextDoor and am now being yelled at in the comments that I informed people wrong (I needed to share the videos) and how I need to get over it cause it’s what I voted for? I’m honestly not sure.

Opinion | Ring is using lost dogs to make the surveillance state adorable The same technology the Amazon-owned company uses to find lost dogs could easily be turned against their owners.

“No matter how Ring and other surveillance tech companies may downplay it, there’s no world in which finding lost dogs is the final end-use for this technology.”
