Phys.org / Off-center stellar death points to wandering supermassive black hole stripped of its own galaxy
Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at ...
Phys.org / Beyond the dust: Families describe daily health challenges near the Salton Sea
A study examining air quality and respiratory health in communities surrounding the Salton Sea in Southern California shows how environmental conditions, poor housing quality and structural inequities combine to place children ...
Medical Xpress / Stem cell scientists engineer 'synthetic organizer' cells to improve kidney organoids
In a study published in Science, USC researchers paired a biological discovery with an engineering feat to create more faithful, reproducible lab-grown kidney structures from stem cells, known as organoids.
Science X / Built-in 'antenna' may help cells sense a healing spark to guide repair after injury
When skin is wounded, it doesn't just send out chemical distress signals; it also generates a subtle electrical field. This "electric beacon" forms as the usual voltage across the tissue collapses, creating a guiding current ...
Phys.org / Deliberate slow growth could explain bacteria survival strategies
Escherichia coli (E. coli) are mostly harmless bacteria that live in the intestines of animals and humans. They are the most well-studied bacteria and, often, when scientists discover something about E. coli, they extrapolate ...
Phys.org / What made trees possible? New research points to drought
A study is reframing a fundamental question in plant evolution: What made trees possible? Researchers from Cal Poly Humboldt, Yale University, the University of Hohenheim in Germany and the Czech Academy of Sciences set out ...
Phys.org / Baker's yeast shows potential in treatment of persistent fungal infection
Millions of women worldwide suffer from vaginal yeast infections. These infections are most commonly caused by the fungus Candida albicans and can lead to symptoms ranging from itching and burning to recurrent inflammation. ...
Medical Xpress / Psychological stress alters gut microbes and ages blood stem cells, mouse study suggests
Psychological stress is increasingly recognized as a risk factor for certain health conditions, including cardiovascular disease and diabetes, especially when paired with an impaired immune response. In a study in Cell Stem ...
Phys.org / World's first synthetic cell with a complete life cycle could revolutionize biological engineering
While many of life's mysteries remain unsolved, every biologist can describe the basic processes performed by a living organism, including energy use, reproduction, growth and development. While these characteristics can ...
Phys.org / Microtubules in ovarian cell bridges may be key to fertility
Female fertility depends on the successful growth and maturation of eggs (oocytes) within ovarian follicles. Within these follicles, the oocyte is surrounded by granulosa cells that supply nutrients, signaling molecules and ...
Phys.org / Gentle nudges for increased animal welfare
Gentle purchase incentives can lead customers to choose groceries with higher animal husbandry standards more often. A recent study at the University of Bonn at least suggests this. The researchers used two different animal ...
Phys.org / Acceptor molecule upconverts low-energy green light to high-energy purple with high efficiency
Solar cells and photocatalysts can be surprisingly inefficient. Despite light consisting of many wavelengths, the range that even highly efficient devices use is limited. Other wavelengths, especially long wavelengths, simply ...
