Phys.org / Black hole feeding bursts may explain JWST's Little Red Dots in early universe
A new theoretical study may have cracked one of the most puzzling discoveries of the James Webb Space Telescope (JWST): Little Red Dots, spotted across the early universe. The paper, posted to the arXiv preprint server on ...
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 / Aerosols may warm or cool the climate depending on timing, new study finds
A new study from the Hebrew University of Jerusalem challenges a long-held assumption in climate science by showing that aerosols—tiny particles suspended in the atmosphere—can either warm or cool the climate, depending on ...
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 ...
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, ...
Phys.org / Twisted stacking lets 2D conductor keep single-layer performance in bulk form
Two-dimensional (2D) materials, which are significantly thinner than a single sheet of paper, have long drawn attention for their exceptional performance. However, they have faced a critical limitation: Their performance ...
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 ...
Phys.org / Chemists unlock first total synthesis of rare plant alkaloid tied to anticancer activity
Plants are undeniably one of nature's most promising sources of new medicines, with monoterpenoid indole alkaloids (MIAs) being a great example. Some intricate compounds are built from multiple-linked chemical units that ...
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 / Corals have a hormonal clock and it looks surprisingly like ours
A three-year study has cracked open the hidden biology behind coral reproduction, revealing hormone cycles that echo those of humans and other animals, and a new way to detect reef distress before it's too late.
Phys.org / Physicists create new family of Schrödinger-cat states
Quantum mechanics, unlike classical physics, allows objects to exist in more than one state at the same time. This idea is often illustrated by Schrödinger's cat, imagined as being both alive and dead until it is observed. ...
Medical Xpress / How often do people pass gas? There's now an app for that
Flatulence, or farting, is something people often joke about or find embarrassing when it happens unexpectedly. It is, however, an essential bodily function that allows the digestive system to keep pressure within the intestinal ...
