Medical Xpress / Selection model helps explain why most human pregnancies are singletons
Each month during a woman's menstrual cycle, an ovary prepares 10–20 antral follicles, fluid-filled sacs that hold immature eggs, for maturation. In most cycles, only one follicle is selected to undergo maturation, eventually ...
Phys.org / Turning vibrations into value—a new catalyst converts CO₂ into useful CO
Researchers at The University of Osaka have developed a catalyst that uses vibrational energy to convert carbon dioxide (CO2) into carbon monoxide (CO), an important industrial feedstock. The work, published in the Journal ...
Medical Xpress / Inside lymph nodes, an overlooked cell type quietly directs immune battles in ways that could reshape medicine
The research group of prof. Sanjiv Luther at the department of immunobiology of the University of Lausanne has discovered that a fibroblast subtype is essential for coordinating certain immune cells within lymph nodes. This ...
Tech Xplore / These penny-size ultrasonic tags ditch batteries and silently turn everyday objects into private smart home trackers
Most smart home devices require power one way or another. You have to plug them in, recharge them, or replace their batteries at some point. Georgia Tech researchers think they have a better way with small metal tags that ...
Phys.org / Room to move: Neutron scattering shows how proteins behave in crowded environments
Proteins are essential molecules in living systems. They move, interact and organize themselves to carry out a wide range of functions, from helping cells communicate to forming structures inside the cell. In many cases, ...
Medical Xpress / 3D DNA switch in brown fat could reshape obesity and diabetes treatment
Most fat stores energy; the body's brown fat does the opposite. Unlike the white fat that accumulates just under our skin, brown fat burns calories and glucose to generate heat. Formally known as brown adipose tissue, it ...
Phys.org / Chernobyl's exclusion zone is a beacon of biodiversity—but it faces new threats from Russia's invasion
April 26 marks the 40th anniversary of the explosion at Reactor 4 of the Chernobyl nuclear power plant in Ukraine. The accident caused the largest ever release of radioactive material into the environment, and at the time ...
Phys.org / From air to tea: New sensor reveals invisible pollution in minutes
Fine particulate matter in the air or nanoparticles in water—a remarkable new technology developed at TU Wien makes it possible to detect tiny amounts of a wide range of substances in a very short time.
Medical Xpress / Human cell model recreates Alzheimer's-linked tau pathology and synapse loss
Researchers at LMU have developed a human cell model that replicates key mechanisms of neurodegenerative diseases—with potential for novel therapies. The paper is published in the journal Science Translational Medicine.
Phys.org / Gene-sharing view challenged as bacteria shown to police DNA exchange
A new study finds that bacteria can actively block the transfer of beneficial genes to neighboring cells, using specialized proteins to specifically destroy shared DNA before it spreads. This challenges the long-held view ...
Phys.org / Atomic-level snapshots reveal how a key copper enzyme powers nature's chemistry
Researchers from the University of Liverpool, Japan, and Argentina have captured atomic-resolution images of an important copper-containing enzyme using advanced X-ray Free Electron Laser (XFEL) technology at SACLA in Japan. ...
Phys.org / Black grouse eye test reveals best flags to protect birds from fatal cables
There is a silent killer lurking in the French Alps: ski lift cables. Over the last 60 years, the wires have accounted for almost 600 recorded landfowl deaths in the region. Black grouse (Lyrurus tetrix) account for ~70% ...
