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 / Scourge of satellites lighting up the sky could be mitigated with help of ultra-black coating
Astrophysicists working to tackle the growing impact of satellite constellations have pioneered a new ultra-black coating as one possible way to mitigate the problem.
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 / Austin neighborhood tap water tests uncover lead and arsenic in homes
For more than a decade, residents of Austin's Colony, a neighborhood in an unincorporated area of southeast Austin outside the city service area, have voiced concern about their tap water's intermittent discoloration and ...
Phys.org / Physicists and AI model Claude 'collaborate' to prove a 10-year-old jamming conjecture
A mathematical problem that had remained unsolved for more than 10 years in the physics of complex systems has finally been resolved through an unusual collaboration: one involving two theoretical physicists and an artificial ...
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 / Mismatched work–life boundaries while working from home can push couples toward breaking up
The COVID-19 pandemic transformed the way people work, making remote and work-from-home (WFH) jobs far more common than ever before. Even after social distancing ended, many companies and employees chose to stick with this ...
Medical Xpress / Inhaled analgesia is as effective as morphine for early pain relief, study shows
Treating pain while in the field can be very demanding. Researchers have finally identified an effective alternative for providing pain relief during the earliest phase of prehospital care, when establishing intravenous access ...
Tech Xplore / Spintronic hardware unlocks faster, lower-energy optimization, outpacing tested quantum annealers
Solving complex optimization problems is central to many modern technologies, from logistics and financial modeling to chip design, communications and artificial intelligence (AI). However, as these problems grow in size, ...
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.
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 / Spider venoms could stop deadly varroa mites killing honey bees
Spider venoms contain ingredients that could lead to a new treatment to protect honeybees from the deadly Varroa destructor mite, according to a study led by the University of the Sunshine Coast. Researchers identified components ...
