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 ...
Phys.org / Simple DNA switch helps tropical butterflies change wing patterns with the seasons
Scientists from the National University of Singapore (NUS) have discovered a simple DNA "switch" that helps tropical butterflies adjust the size of their wing eyespots in response to seasonal temperatures, shedding light ...
Phys.org / Recyclable fluorine improves properties of degradable polyester plastics
Incorporating fluorine into certain polyesters accelerates polymer chain formation, makes longer chains accessible, and enables targeted modification of the material's properties. As a result, fluorinated polyesters become ...
Phys.org / Engineers create bioelectronic hydrogels to monitor activity in the body
Wearable or implantable devices to monitor biological activities, such as heart rate, are useful, but they are typically made of metals, silicon, plastic and glass and must be surgically implanted. A research team in the ...
Phys.org / Light reshapes ferroelectric thin films for wireless sensors and micro-devices
The potential of using low-energy light to shape ferroelectric thin films for micro devices is advancing with an international team of researchers most recently reporting success with "photostriction."
