Phys.org / Microwave pulses can control ion-molecule reactions at near absolute zero
A key objective of ongoing research rooted in molecular physics is to understand and precisely control chemical reactions at very low temperatures. At low temperatures, the chemical reactions between charged particles (i.e., ...
Phys.org / Animal behavioral diversity at risk in the face of declining biodiversity
Our environment is changing rapidly, largely as a result of human activities, leading to a significant decline in biodiversity. According to researchers from the University of Victoria and the Max Planck Institute for Evolutionary ...
Phys.org / HD 144812 is a rare post-red supergiant star in a binary system, observations find
Astronomers from the Czech Republic and Argentina have employed the Gemini South telescope to observe a yellow supergiant star designated HD 144812. The observations found that HD 144812 is a rare post-red supergiant orbited ...
Phys.org / Climate change and prehistoric human populations: Study finds eastward shift of settlement areas at end of last Ice Age
A new study sheds light on how prehistoric hunter-gatherer populations in Europe coped with climate changes over 12,000 years ago. Led by scientists from the University of Cologne, a team of 25 prehistoric archaeologists ...
Phys.org / Some insects are declining, but what's happening to the other 99%?
Insects are the dominant form of animal life on our planet, providing humans and wildlife with pollination, food, and recycling services but, despite concerns about population declines, little is known about how 99% of species ...
Phys.org / Antibiotic resistance among key bacterial species plateaus over time, study shows
Antibiotic resistance tends to stabilize over time, according to a study published in the open-access journal PLOS Pathogens by Sonja Lehtinen from the University of Lausanne, Switzerland, and colleagues.
Phys.org / Intriguing excess of top-quark pairs hints at discovery of smallest composite particle
The CMS collaboration at CERN has observed an unexpected feature in data produced by the Large Hadron Collider (LHC), which could point to the existence of the smallest composite particle yet observed. The result, reported ...
Phys.org / Fluorescent biosensor tracks plant RNA in real time for better crops and biosecurity
Scientists at Oak Ridge National Laboratory have developed the first-ever method of detecting ribonucleic acid, or RNA, inside plant cells using a technique that results in a visible fluorescent signal. The technology can ...
Phys.org / Stem cell barcoding reveals how the brain and inner ear are formed
Researchers at Karolinska Institutet have developed a method that shows how the nervous system and sensory organs are formed in an embryo. By labeling stem cells with a genetic "barcode," they have been able to follow the ...
Phys.org / Cellular regulator of mRNA vaccine revealed, offering new therapeutic options
A team of researchers led by Dr. Kim V. Narry, director of the Center for RNA Research at the Institute for Basic Science (IBS), has uncovered a key cellular mechanism that affects the function of mRNA vaccines and therapeutics.
Phys.org / Physicists uncover electronic interactions mediated via spin waves
Research by physicists at The City College of New York is being credited for a novel discovery regarding the interaction of electronic excitations via spin waves. The finding by the Laboratory for Nano and Micro Photonics ...
Phys.org / Engineers develop a way to mass manufacture nanoparticles that deliver cancer drugs directly to tumors
Polymer-coated nanoparticles loaded with therapeutic drugs show significant promise for cancer treatment, including ovarian cancer. These particles can be targeted directly to tumors, where they release their payload while ...
