Millions of years ago, animals adapted to become warm-blooded amid huge climactic changes. Now scientists hope these clues from the past could help us understand what lies ahead by Tiffany Cassidy.

Your large language model is secretly a capable regressor when given in-context examples.
We analyze how well pre-trained large language models (e.g., Llama2, GPT-4, Claude 3, etc) can do linear and non-linear #regression when given…

What do bird dreams sound like?

For more than 20 years, researchers have known that areas of birds’ brains dedicated to singing show neural patterns during sleep akin to the ones they use while awake and singing.

One hundred twenty satellites, with their own distinct purpose, hover our Earth. How the structure of continents, the sun, human interaction and many other factors contribute to Earth’s climate and survival/evolution of life.
A new way of interpreting the elusive mathematics of quantum mechanics could fundamentally change our understanding of reality.
Physical touch from both humans and animals can reduce pain, feelings of depression, and anxiety in adults and children, according to a systematic review and meta-analysis published in Nature Human Behaviour. Read the paper:
This pre-registered systematic review and multilevel meta-analysis examined the effects of receiving touch for promoting mental and physical well-being, quantifying the efficacy of touch interventions for different ways of administration.

Anyone who needs an unusual mole on their skin checked out may soon get to skip a surgical biopsy, and instead have a virtual biopsy. This tool could be a quick, uninvasive way to identify cancerous cells, as well as reveal any cancerous tissue that might be present and left behind during a surgery. This new tool uses lasers to and generate a three-dimensional reconstruction of cells in a tissue under analysis. Cross-sectional images of that tissue can then be assessed, like slides on a microscope. This work may one day be used not only on skin, but on other parts of the body. The work has been reported in Science Advances.
“We’ve not only created something that can replace the current gold-standard pathology slides for diagnosing many conditions, but we actually improved the resolution of these scans so much that we start to pick up information that would be extremely hard to see otherwise,” said senior study author Adam de la Zerda, PhD, an associate professor of structural biology at Stanford University.
A team of researchers at the Leuven-based Neuro-Electronics Research Flanders (NERF) details how two different neuronal populations enable the spinal cord to adapt and recall learned behavior in a way that is completely independent of the brain.
These remarkable findings, published today in Science, shed new light on how spinal circuits might contribute to mastering and automating movement. The insights could prove relevant in the rehabilitation of people with spinal injuries.
The spinal cord modulates and finetunes our actions and movements by integrating different sources of sensory information, and it can do so without input from the brain.
