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 / Molecular clock analysis shows bacteria used oxygen long before widespread photosynthesis
Microbial organisms dominate life on Earth, but tracing their early history and evolution is difficult because they rarely fossilize. Determining when exactly a particular group of microbes first appeared is especially hard. ...

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 / When a black hole winks at you: Variability identified in supermassive black hole in Andromeda galaxy
A Michigan State University researcher saw X-rays coming from a black hole using the NASA Chandra X-Ray Observatory telescope.

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 / A 32-bit RISC-V processor made using molybdenum disulfide instead of silicon
A team of engineers at Fudan University has successfully designed, built and run a 32-bit RISC-V microprocessor that uses molybdenum disulfide instead of silicon as its semiconductor component. Their paper is published in ...

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 ...

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 / 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 / Bizarre-looking dinosaur challenges what we know about the evolution of fingers
Oviraptorosaurs are weird dinosaurs that look a bit like flightless birds. But these ancient animals aren't just funny-looking fossils. As my team's new research published in Royal Society Open Science shows, they can help ...

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 ...
