Phys.org / A new route to synthesize multiple functionalized carbon nanohoops
The field of nanomaterials is witnessing a transformative shift at the intersection of organic chemistry and molecular engineering. Among the most promising molecular structures are carbon nanohoops, of which [n]cycloparaphenylenes ...
Phys.org / Raman sensors with push-pull alkyne tags amplify weak signals to track cell chemistry
Seeing chemistry unfold inside living cells is one of the biggest challenges of modern bioimaging. Raman microscopy offers a powerful way to meet this challenge by reading the unique vibrational signatures of molecules. However, ...
Phys.org / Net-casting spiders' adjustable silk stiffness point to tunable fiber design
What makes spider silk so extraordinarily strong and elastic at the same time? This was the focus of recent investigations carried out by researchers from the University of Greifswald, the University of Bonn and the Museum ...
Phys.org / How gut bacteria share antibiotic resistance genes and fuel dangerous hospital infections
Researchers from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine), have uncovered how a high-risk class of genetic vectors can efficiently spread antibiotic resistance within the gut, enabling ...
Phys.org / Parasite behind toxoplasmosis hides multiple distinct subtypes inside each cyst
A University of California, Riverside team of scientists has found that Toxoplasma gondii, a common parasite affecting up to one-third of the global population, is far more complex than previously believed. The findings, ...
Phys.org / A specific immune system protein may drive antibiotic tolerance
If you have had strep throat or an ear infection, there's a good chance you received amoxicillin or penicillin to effectively kill the troublesome bacteria. These drugs, which belong to a broad group of antibiotics called ...
Phys.org / How a vital DNA protection protein complex adapts to new threats without compromising its essential functions
In Lewis Carroll's "Through the Looking-Glass," Alice is stuck in a never-ending race with the Red Queen yet never gains a lead. "It takes all the running you can do to keep in the same place," the Queen says. "Though we ...
Phys.org / Trust in Ph.D. advisor can predict a good grad school experience
The advisor-advisee relationship is central to most doctoral education models. Yet not all students trust their advisors. Danfei Hu, Jonathan E. Cook and colleagues sought to examine the importance of this relationship to ...
Phys.org / Mapping cell development with mathematics-informed machine learning
The development of humans and other animals unfolds gradually over time, with cells taking on specific roles and functions via a process called cell fate determination. The fate of individual cells, or in other words, what ...
Phys.org / Changes to cougar diets and behaviors reduce their competition with wolves in Yellowstone, study finds
A new study shows that interactions between wolves and cougars in Yellowstone National Park are driven by wolves stealing prey killed by cougars and that shifts in cougar diets to smaller prey help them avoid wolf encounters. ...
Phys.org / Spider monkeys pool their knowledge to find the best fruit
When spider monkeys want to tell others about the best fruit trees in the forest or ones they've missed, they do so by changing their social groups to share what they know, according to a new study published in the journal ...
Phys.org / High-resolution map shows dark matter's gravity pulled normal matter into galaxies
Scientists have created the highest resolution map of the dark matter that threads through the universe—showing its influence on the formation of stars, galaxies and planets.
