Phys.org / Elusive tularemia proteins reveal possible treatment target in rare tick-borne disease
Tularemia is a rare but highly infectious disease caused by Francisella tularensis, a bacterium that can evade immune defenses. Symptoms of infection can include fever, swollen lymph nodes, and—in some cases—pneumonia. What ...
Phys.org / Q&A: Scientists decode the logic behind cells' mysterious protein stockpiles
As far as research subjects go, it's not always easy to find common ground with a single-celled bacterium. Yet the more Paul Wiggins studies his model bacteria, Acinetobacter baylyi, the more he sees surprising commonalities ...
Phys.org / DNA cracks nutmeg's hidden past, revealing a South Moluccas origin and a prehuman journey north
A sprinkle of nutmeg powder on baked goodies or mashed potatoes can immediately lift the flavor with its warm and sweet aroma. Even though it is used globally, not much is known about the true origins of the nutmeg spice ...
Phys.org / Universal quantum protocol extracts maximum work without knowing a system's state in advance
A new study published in Nature Communications has shown that in the asymptotic limit, extracting the maximum possible work from many copies of a quantum system does not require knowing exactly what state that system is in.
Tech Xplore / This punishing coastal ferry route forces a radical rethink of clean speed at sea
The shipping industry must cut its climate emissions, and express ferries are the means of passenger transport that causes the most pollution per kilometer. These high-speed passenger vessels with diesel engines are currently ...
Phys.org / Bringing quantum time into the lab—a single clock can run young and old at once
Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum physics, this relativistic ...
Phys.org / How cells turn mechanical forces into biochemical signals
Cells constantly probe their environments, searching for physical cues that guide their behavior. And yet a cell's response to its environment is always biochemical, mediated by the chemistry of its internal protein machinery. ...
Phys.org / NASA's Curiosity rover uncovers metal‑rich hotspot tied to ancient Martian lake
A team of scientists using the ChemCam instrument on NASA's Curiosity Mars rover has discovered the highest amounts of iron, manganese, and zinc ever found together in Gale Crater on Mars. Minerals with these metals were ...
Medical Xpress / How a tiny circle of repeat offenders poisoned 100s of gold-standard medical trials for over a decade
Randomized Controlled Trials (RCTs) are the gold standard of medical research as random assignment approach helps eliminate bias and yields the most reliable evidence on whether a treatment truly works. Since RCTs sit at ...
Medical Xpress / A fresh take on the 'COVID Generation': How the pandemic may have changed young people for the better
At the peak of the pandemic in 2021, teenagers from Sackets Harbor, N.Y. got certified as ambulance drivers and took over running the local emergency medical service when the usual, much older, volunteers had to step away ...
Phys.org / Monkeys in Gibraltar self-medicate with soil to help them digest tourists' junk food
Monkeys in a tourism hotspot have learned that swallowing dirt can quell the upset stomachs caused by overconsumption of sweet and salty snacks fed to them by holidaymakers, a new University of Cambridge-led study suggests. ...
Medical Xpress / Paxlovid looked like a COVID game-changer, but in vaccinated adults the real story is far more complicated
The results of two clinical trials—led by the Upstream Lab at St. Michael's Hospital in Toronto and Oxford University, published in the New England Journal of Medicine—provide new evidence to consider when funding, prescribing, ...
