Phys.org / Python scales host microstructures that block bacterial biofilms—revealing potential for antimicrobial materials
Materials inspired by nature, or biomimetic materials, are nothing new. Scientists have designed water-resistant materials inspired by lotus leaves and rose petals, unsinkable metals based on the air-trapping, buoyant abilities ...
Medical Xpress / Why COVID and flu hit older lungs harder: Aging tissue may bring on immune dysregulation
Older adults are much more likely to become seriously ill from flu or COVID because aging lung cells can drive excessive immune responses, according to a new study led by researchers at UC San Francisco. The findings enhance ...
Phys.org / Male bats sing in the rotor-swept zone of wind turbines, potentially raising collision risk
A research team led by the Museum für Naturkunde presents the first evidence that several bat species produce courtship songs in the immediate rotor-swept zone of wind turbines while circling around the nacelle. Data from ...
Phys.org / Did you hear the one about scientists telling jokes? Not many did, according to a study of humor at conferences
To engage audiences and help keep their attention, many public speakers sprinkle their speeches with a little humor. It's a useful tool, but something that scientists rarely use, according to a report into humor at science ...
Medical Xpress / AI-powered 'lab-on-a-chip' platform may enable same-day treatment decisions for pediatric patients
Scientists at the University of Utah (the U) have developed a new "lab-on-a-chip" device that uses artificial intelligence to rapidly predict cancer cell sensitivity to targeted therapies for children with T-cell acute lymphoblastic ...
Phys.org / Unlocking the cell's 'gatekeeper': Researchers discover critical RNA quality-control factor, LENG8
How do cells ensure that the "blueprints" of genetic information-RNA are accurate and intact before they are exported from the nucleus to the cytoplasm for protein production? A study led by Professor Yongsheng Shi's team ...
Tech Xplore / Molecular umbrella can protect solar cells by blocking ion migration
Perovskites are semiconducting materials that have rapidly transformed the field of optoelectronics, demonstrating outstanding performance in light-emitting diodes (LEDs) and photodiodes. For their unique properties, they ...
Phys.org / 600-year-old pinot noir grape found in medieval French toilet
A 600-year-old grape seed discovered in the toilets of a medieval French hospital is genetically identical to the grapes still being used to make pinot noir wine, scientists said Tuesday.
Phys.org / Scientists detect magnetic waves deep within the sun, helping predict solar activity
Researchers at NYU Abu Dhabi have discovered new large-scale waves moving deep inside the sun, driven by magnetic fields far below the surface. These waves provide a window into parts of the sun that are otherwise inaccessible, ...
Phys.org / Bioluminescent bacterial partner proves essential for squid development
The Hawaiian bobtail squid, a small, multi-colored native of coastal waters in Hawai'i, uses bioluminescence to camouflage itself and evade predators. However, the costume change is only possible through an exclusive symbiotic ...
Phys.org / Programmable superconducting diode can flow on command
A team of researchers led by the University of Pittsburgh demonstrated a programmable superconducting diode at the LaAlO3/KTaO3 (LAO/KTO) interface, an advance that holds potential to enhance/help usher in the future of next-generation ...
Phys.org / Quantum computer accurately simulates real magnetic materials, reproducing national laboratory data
Studying and designing novel materials is a central application of quantum mechanics. Chemists, materials scientists, and physicists focus on subtle interactions in quantum materials and to uncover them they rely on sophisticated ...
