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 / Beachcomber's find fuels whale study breakthrough
During his morning runs, Rod Keogh had no doubt that the whale poo he saw washed up on the beach had value. Science has finally caught up with him. Samples collected by the South Australian man have contributed to a groundbreaking ...
Phys.org / Light flips bacterial signaling enzyme between two shapes, unlocking how signals travel
Researchers at the University of Bayreuth and Forschungszentrum Jülich have demonstrated that specific light-sensitive enzymes—so-called sensor histidine kinases (SHKs)—transmit their signal through a light-controlled change ...
Phys.org / Fish in a polluted Mexican river may mate with the wrong species, leading to hybrid offspring
The byproducts of modern society appear to be messing with the love life of two tiny fish species that have long coexisted in Mexican rivers.
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 ...
Tech Xplore / Electric car analysis reveals moral case for accelerating green transition
Recently, it has been argued that a rapid transition is unjust—particularly because of concerns about mining critical minerals, including for EVs. Specific concerns have been raised about deaths among artisanal and small-scale ...
Medical Xpress / Dynamic protein behavior drives blood-brain barrier specialization, study reveals
A study led by researchers at the Institute for Bioengineering of Catalonia (IBEC), in collaboration with the Proteomics Platform of the Institute for Research in Biomedicine (IRB Barcelona), has uncovered a key mechanism ...
Phys.org / Could this asteroid be a piece of the moon? A Chinese spacecraft is about to find out
The moon is not the only natural object traveling through space alongside Earth. Several small asteroids travel around the sun in near lockstep with our planet. And just like Earth, these space rocks also take a year to complete ...
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 ...
Phys.org / Coastal and estuarine carbon removal technique may backfire when pushed too far
Scientists investigating a proposed way to remove carbon dioxide from the atmosphere using seawater have found that adding too much alkalinity to neutralize acids can trigger chemical reactions that undermine the process.
Phys.org / If we force online platforms to control harmful content, where does that leave sex ed?
Most of us have attended sex ed classes in school. If we're lucky, we'll learn about consent and how to roll a condom onto a banana. But the classroom rarely goes into the specifics of sexual health and well-being—including ...
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.
