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 / 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 / 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 / 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 ...
Phys.org / Cross-organelle coordination in yeast enhances production of valuable plant compounds
A team of researchers led by the University of California San Diego has discovered a new way to make yeast cells more efficient "factories" for producing valuable plant compounds. The advance could enable the sustainable ...
Phys.org / Permafrost study finds abrupt thaw accelerates soil phosphorus cycling, offsetting carbon release
Permafrost thaw can stimulate the release of soil carbon, triggering a positive carbon-climate feedback that may be mediated by changes in soil phosphorus (P) availability.
Phys.org / Controlled atomic defects in nickelate films narrow down explanations of superconductivity emergence
An international team led by researchers at MPI-CPfS used irradiation with extremely high-energy electrons to controllably introduce atomic defects in superconducting nickelate thin films. Their systematic investigation recently ...
