How hunting may have turned humans into long-distance runners

How hunting may have turned humans into long-distance runners

Humans are uniquely adapted to running long distances, and can even eventually6 chase down horses and cheetahs. Researchers have discovered hundreds of historical accounts of humans hunting prey by chasing them down over long distances, which some believe is why we evolved our unique talent for endurance running. While speedy animals such as cheetahs or … Read more

Researchers develop ‘game-changing’ blood test for stroke detection

Researchers develop ‘game-changing’ blood test for stroke detection

Stroke is the leading cause of disability worldwide and the second leading cause of death, but the right early intervention can prevent severe consequences. A new study led by investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, and collaborators developed a new test by combining blood-based biomarkers … Read more

Researchers realize multiphoton electron emission with non-classical light

Researchers realize multiphoton electron emission with non-classical light

Experimental scheme. Credit: Nature Physics (2024). DOI: 10.1038/s41567-024-02472-6 Strong field quantum optics is a rapidly emerging research topic, which merges elements of non-linear photoemission rooted in strong field physics with the well-established realm of quantum optics. While the distribution of light particles (i.e., photons) has been widely documented both in classical and non-classical light sources, … Read more

Deep-sea sponge’s ‘zero-energy’ flow control could inspire new energy efficient designs

Researchers develop ‘game-changing’ blood test for stroke detection

The Venus flower basket sponge, with its delicate glass-like lattice outer skeleton, has long intrigued researchers seeking to explain how this fragile-seeming creature’s body can withstand the harsh conditions of the deep sea where it lives. Now, new research reveals yet another engineering feat of this ancient animal’s structure: its ability to filter feed using … Read more

Composition of gut microbiota could influence decision-making

Commensal bacteria (red) among the mucus (green) and epithelial cells (blue) in a mouse small intestine. Credit: University of Chicago. The way we make decisions in a social context can be explained by psychological, social, and political factors. But what if other forces were at work? Hilke Plassmann and her colleagues from the Paris Brain … Read more

Ion irradiation offers promise for 2D material probing

Researchers develop ‘game-changing’ blood test for stroke detection

Two-dimensional materials such as graphene promise to form the basis of incredibly small and fast technologies, but this requires a detailed understanding of their electronic properties. New research demonstrates that fast electronic processes can be probed by irradiating the materials with ions first. A collaboration involving researchers at the University of Illinois Urbana-Champaign and the … Read more

Pyramids built along long-lost river, scientists discover

Pyramids built along long-lost river, scientists discover

A river once ran alongside many of Egypt’s pyramids, which helped to move the massive materials that built the famous monuments, scientists say. Scientists have discovered a long-buried branch of the Nile river that once flowed alongside more than 30 pyramids in Egypt, potentially solving the mystery of how ancient Egyptians transported the massive stone … Read more
