Phys.org / DNA from Napoleon's 1812 army identifies pathogens likely responsible for the army's demise during retreat from Russia
In the summer of 1812, French emperor Napoleon Bonaparte led about half a million soldiers to invade the Russian Empire. But by December, only a fraction of the army remained alive. Historical records suggest that starvation, ...
Phys.org / Three Earth-sized planets discovered in a compact binary system
An international team of researchers has just revealed the existence of three Earth-sized planets in the binary stellar system TOI-2267 located about 190 light-years away. This discovery, published in Astronomy & Astrophysics, ...
Phys.org / How axolotls rely on their 'fight or flight' network to regenerate body parts
Biologists have long been fascinated by the ability of salamanders to regrow entire limbs. Now Harvard researchers have solved part of the mystery of how they accomplish this feat—by activating stem cells throughout the ...
Phys.org / The beginning of the universe: Cosmic inflation with standard particle physics repertoire
How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the first, very rapid expansion ...
Phys.org / Astronomers capture radio signals from comet 12P/Pons-Brooks
A research team led by the Shanghai Astronomical Observatory of the Chinese Academy of Sciences has used the Tianma Radio Telescope to conduct multi-band radio observations of the returning comet 12P/Pons-Brooks (12P). They ...
Phys.org / Physicists create the smallest pixel in the world (so far)
Smart glasses that display information directly in the field of vision are considered a key technology of the future—but until now, their use has often failed due to cumbersome technology. However, efficient light-emitting ...
Phys.org / Floral-scented fungus lures mosquitoes to their doom
In the battle against mosquito-borne diseases that kill hundreds of thousands of people each year, scientists turned to an unlikely ally: a fungus that smells like flowers.
Phys.org / Electrohydrodynamics pump and machine learning enable portable high-performance excimer laser
According to a recent study published in APL Photonics, a research team led by Prof. Liang Xu from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed an ultra-compact excimer laser roughly ...
Phys.org / Electromagnetic device identifies cells by seeing how high they levitate
It looks like a magic trick: Cells at the bottom of a liquid medium begin levitating, then hovering at a particular height. With no physical contact, an invisible force directs certain cells to float up or down in unison, ...
Phys.org / Gene variant that protects against norovirus spread with arrival of agriculture, prehistoric DNA reveals
The arrival of agriculture coincided with a sharp rise in a gene variant that protected against the virus that causes winter vomiting, researchers from Karolinska Institutet and Linköping University report after analyzing ...
Phys.org / Search for elusive neutrino multiplets tightens limits on cosmic particle origins
The origins of extremely high-energy particles that fill the universe—such as protons, electrons, and neutrinos—remain one of the longest-standing mysteries in modern astrophysics. A leading hypothesis suggests that "explosive ...
Phys.org / Pressure turns Ångström-thin semiconducting bismuth into a metal, expanding options for reconfigurable electronics
Two-dimensional (2D) materials, sparked by the isolation of Nobel-prize-winning graphene in 2004, has revolutionized modern materials science by showing that electrical, optical, and mechanical behaviors can be tuned simply ...
