Medical Xpress / Tiny protein tail helps one immune gene fight two very different viruses
Our genomes contain hundreds of genes with antiviral jobs that are called into action when a virus succeeds in infecting one of our cells. By acting cooperatively, these genes provide defense against a wide range of viruses, ...
Phys.org / DNA design unlocks nanometer-scale catalyst control for cleaner hydrogen production
The fixed idea that DNA is only a molecule that stores genetic information is being challenged. KAIST researchers have developed a technology that controls the chemical environment around catalysts at the nanometer scale ...
Phys.org / Plants could be used to grow medicines in space, study shows
Astronauts on long space missions may one day use plants to produce fresh stocks of medicines on demand, thanks to new research by engineers at the University of California San Diego. The team developed a simple method to ...
Phys.org / Medicinal plants yield carbon nanoparticles that glow red and flag toxic metals
What do iron, lead and nickel have in common? These heavy metals are an indispensable part of many industries. However, they also share a dark reality: They are serious environmental and public health threats. Every day, ...
Tech Xplore / Organic transistor unites memory, signal processing and light emission below 3.5 V
Seoul National University researchers have developed an ultra-low-voltage electrochemical organic light-emitting transistor that can simultaneously perform signal processing, memory and light emission within a single semiconductor ...
Phys.org / How wax moth larvae can help reduce animal testing in research
Researchers at the Helmholtz Institute for One Health (HIOH) have demonstrated that larvae of the greater wax moth, Galleria mellonella, are suitable as an alternative infection model for investigating the pathogenicity of ...
Phys.org / Ancient hominins selected basalt sources for specific tools nearly 800,000 years ago, study reveals
A new study finds that ancient hominins nearly 800,000 years ago deliberately selected specific basalt sources for different stages of tool production rather than simply using whatever stone was available nearby. By tracing ...
Medical Xpress / New GLP-1 oral pill lowers blood sugar and reduces bodyweight, clinical trial finds
Oral GLP-1 medications have the potential to increase access to therapies that can help lower blood sugar and reduce bodyweight. At the American Diabetes Association's Scientific Session, Mass General Brigham physician investigator ...
Medical Xpress / Left-handed DNA tubes double cancer drug killing by boosting cell uptake
Researchers in the lab of Cancer Center at Illinois (CCIL) member Xing Wang have discovered the influential role of structural chirality, or "handedness," of a DNA nanostructure to dictate cancer cell response to targeted ...
Medical Xpress / Resistance training appears to restore physical strength, immune health in frail or at-risk cancer survivors
Cancer survivors significantly improved their strength and immune health after completing a 10-week resistance training program as part of a pilot study led by Shernan Holtan, MD, Chief of Blood and Marrow Transplantation ...
Medical Xpress / Target trial does not suggest major adverse outcomes with early GLP-1 use in pregnancy
A target trial emulation estimated the risks associated with glucagon-like peptide-1 receptor agonist (GLP-1RA) exposure in early pregnancy. The findings did not indicate a substantially increased risk for nonlive birth, ...
Phys.org / New Relative Niño index introduces more robust way to measure El Niño strength
A new El Niño index that provides a more climate-robust measure of the strength of El Niño signals has been released by the European Centre for Medium-Range Weather Forecasts (ECMWF). With the World Meteorological Organization's ...
