Phys.org / Gaia finds hints of planets in baby star systems
Ever wondered how planetary systems like our own solar system form? Thanks to the European Space Agency's Gaia space telescope, we're getting a unique peek behind the cosmic curtain into these dusty environments.
Phys.org / Interpretable neural networks help reveal the nature of dark matter
A research team from the Xinjiang Astronomical Observatory (XAO) of the Chinese Academy of Sciences has developed an interpretable artificial intelligence (AI) framework named Convolutional Kolmogorov–Arnold Network (CKAN), ...
Phys.org / Bacterium hijacks fruit ripening program in citrus plants to steal sugars, research reveals
The bacterial pathogen Xanthomonas citri, which causes canker disease in citrus trees, activates selected parts of the fruit ripening program inside infected leaves. Normally, this program makes citrus fruits soften and sweeten ...
Phys.org / Improved tracer labeling expands PET imaging possibilities
Imagine being able to watch organs and tissues work in real time. That's the power of Positron Emission Tomography (PET) imaging, a technology that gives physicians and researchers a window into cellular processes.
Phys.org / Common virus 'rewires' intracellular mechanisms to promote infection
Investigators from the laboratory of Derek Walsh, Ph.D., professor of Microbiology-Immunology, have discovered how human cytomegalovirus rewires intracellular mechanisms to control the movement of the cell nucleus, promoting ...
Phys.org / DNA caught on old air filters reveals hidden past of ecosystems
DNA captured on air filters and stored since the 1960s acts as an ecological time capsule, according to a recent publication in Nature Communications. The findings show that tiny fragments of genetic material can paint a ...
Phys.org / Tiny viral 'switch' offers hope against drug-resistant bacteria
As antibiotic-resistant infections rise and are projected to cause up to 10 million deaths per year by 2050, scientists are looking to bacteriophages, viruses that infect bacteria, as an alternative.
Phys.org / Spray-on antibacterial coating offers new protection for plants against disease and drought
Engineers at the University of California San Diego have developed a spray-on polymer coating that could help plants resist harmful bacterial infections and survive drought. The advance, published in ACS Materials Letters, ...
Phys.org / Flat-band ultrastrong coupling between phonons and plasmons observed for first time
Researchers from CIC nanoGUNE, in collaboration with the Donostia International Physics Center (DIPC) and the Center for Materials Physics (CFM), have experimentally observed and theoretically verified flat-band ultrastrong ...
Phys.org / New machine-learning models capture the rapid evolution of antimicrobial resistance
Antimicrobial resistance (AMR) is an increasingly dangerous problem affecting global health. In 2019 alone, methicillin-resistant Staphylococcus aureus (MRSA) accounted for more than 100,000 global deaths attributable to ...
Phys.org / A new natural sunscreen: Novel compound discovered in thermophilic cyanobacteria
Natural sunscreens shield the skin from harmful radiation, without triggering allergic reactions. In a recently published study, a group of researchers has discovered a novel compound, β-glucose-bound hydroxy mycosporine-sarcosine, ...
Phys.org / 'Speed scanner' can test thousands of plant gene switches at once
Agriculture, from the outset, has been made possible by humans tweaking the genes of plants to make them grow faster, produce more of what we want, and survive drought, pests, and infection. For millennia, we did it with ...
