Fuente: earth.com Published by Andrei Ionescu (Earth.com staff writer) in earth.com on 20 March 2026 Birch tar has long appeared at Neanderthal sites as a black, sticky residue – usually explained as a kind of prehistoric glue used to hold tools together. However, that simple picture may be missing something important. A new study from the  University of Cologne  and the  University of Oxford   suggests the same substance that helped Neanderthals build their tools may also have helped them treat wounds . When researchers recreated birch tar using ancient methods, they found it could slow the growth of bacteria linked to infection . The findings don’t prove Neanderthals practiced medicine . But they add to a growing body of evidence that these early humans were more than skilled hunters – they may also have been practical caregivers , using the materials around them to manage injury and disease.

Brain Activity Reveals How Well We Mentally Size Up Others Originally published by Univeristät Zürich on 9 March 2026 Humans often adapt their behavior to that of other people with lightning speed. A new study by the University of Zurich reveals what brain networks govern social mentalization and adaptatio n, making it possible to predict how flexibly one person reacts to others . The findings of the study could provide new approaches to gaining a better understanding of social disabilities such as autism spectrum disorder or borderline personality disorder . In the interaction with other people, we constantly assess what they think and intend. A new study by the University of Zurich (UZH) shows which brain networks are involved. (Image: iStock / DrAfter123) How quickly do we perceive whether a person we are interacting with is clever or predictable ? Be it in a game, a conversation or a negotiation, we constantly infer what others are thinking and size up their intentions , a...

Though natural and engineered systems share an overarching goal —providing a mechanism for interacting components to transmit information— one system appears to have a clear advantage, according to f indings published recently by a University of New Mexico-led team . In this case, the team found that nature does its best when it comes to networks. New study compares natural and man-made networks "The Frequency Response of Networks as Open Systems,"  published  in  Nature Communications , was authored by former UNM graduate student Amirhossein Nazerian , now at Colorado State University; Malbor Asilani, Florid...

Proteins assume complex 3D shapes even faster than does DNA , which is a simpler molecule. Originally wri tten By  Katherine Bourzac and published in Nature on 9 March 2026 It can take less than a microsecond for proteins (artist’s impression) to fold into their 3D shapes. Credit: Christoph Burgstedt/Science Photo Library Scientists say they have made some of the first direct measurements of how long it takes an individual, ordinary protein to fold . The results were surprising: they found no relationship between a protein’s sequence or size and how long it takes to  fold into its 3D shape . And proteins seem to fold more efficiently than do other biomolecules, such as DNA — despite proteins having a more complex set of ingredients. The work was published today in  Physical Review Letters 1 . Read more

Originally published by Marc Zimmer ,  The Conversation , on March 1, 2026 edited by  Lisa Lock , reviewed by  Alexander Pol Credit: Pixabay/CC0 Public Domain Fruit flies, mice , zebrafish , yeast , and the tiny worm  C. elegans  are  model organisms  that have carried modern biology on their backs. Scientists did not choose them for their charisma. They were chosen because their similarities illuminate biological principles across many species. Their biology is simple enough for researchers to master yet deep enough to keep  delivering new insights centuries later . But biologists don't have a common reference point for a vast area of the field:  proteins, the cell's doers . Proteins catalyze chemical reactions, give cells their structure, and help them communicate with each other. Most organisms use tens of thousands of protein types, and each can be mutated , modified , and measured in different ways and in countless environments...

Published in phys.org by  University of Waterloo on February 24, 2026 edited by  Sadie Harley , reviewed by  Robert Egan Under a low magnification of 1.9X, this image depicts a close-up view of a Petri dish culture plate that contained a medium of egg yolk agar, which was inoculated with Clostridium sporogenes bacteria. These organisms gave rise to these colonies after a 48 hour incubation period. Zones of opacity were noted beneath these colonies. Credit: CDC, Public Domain A research team led by the University of Waterloo is developing a novel tool to treat cancer by engineering hungry bacteria to literally eat tumors from the inside out . "Bacteria spores enter the tumor, finding an environment where there are lots of nutrients and no oxygen , which this organism prefers, and so it starts eating those nutrients and growing in size," said Dr. Marc Aucoin, a chemical engineering professor at Waterloo. "So, we are now colonizing that central space , and the bacter...
