Phys.org / Electron-phonon instability in graphene revealed by global and local noise probes
Understanding nonequilibrium phenomena to effectively control it is an outstanding challenge in science and engineering. In a recent study, Trond. I. Andersen and colleagues at the departments of physics, chemistry, materials ...
Phys.org / Researchers create artificial mother-of-pearl using bacteria
The strongest synthetic materials are often those that intentionally mimic nature.
Phys.org / Atomic beams shoot straighter via cascading silicon peashooters
To a non-physicist, an "atomic beam collimator" may sound like a phaser firing mystical particles. That might not be the worst metaphor to introduce a technology that researchers have now miniaturized, making it more likely ...
Phys.org / X-ray observations reveal insights into the nature of the pulsar wind nebula 3C 58
Analysis of the new data from X-ray observations using NASA's NuSTAR spacecraft and archival data from the agency's Chandra X-ray space observatory, has yielded more insights into the nature of a pulsar wind nebula (PWN) ...
Phys.org / Scientists find auroral 'speed bumps' are more complicated
Researchers at the University of New Hampshire Space Science Center find that "speed bumps" in space, which can slow down satellites orbiting closer to Earth, are more complex than originally thought.
Phys.org / Meet B. fragilis, a bacterium that moves into your gut and evolves to make itself at home
MIT researchers have analyzed population genomics and metagenomics to investigate the microbiome evolution of Bacteroides fragilis, one of the most prevalent bacteria found in humans' large intestines. In a paper published ...
Phys.org / Scientists create first billion-atom biomolecular simulation
Researchers at Los Alamos National Laboratory have created the largest simulation to date of an entire gene of DNA, a feat that required one billion atoms to model and will help researchers to better understand and develop ...
Phys.org / New studies highlight challenge of meeting Paris Agreement climate goals
New research highlights the "incredible challenge" of reaching the Paris Agreement without intense action and details the extreme temperatures parts of the planet will suffer if countries fail to reduce emissions.
Phys.org / Simple sea anemones not so simple after all
The tube-dwelling anemone is an ancient sea creature that resembles a prehistoric flower. The animals live slow, long and predictable lifestyles and look fairly similar from species to species.
Phys.org / Study: Why unique finches keep their heads of many colors
There appears to be an underlying selection mechanism at work among Gouldian Finches—a mechanism that allows this species to produce and maintain individuals with red heads, black heads, and yellow heads. Research by scientists ...
Phys.org / Research team discovers perfectly imperfect twist on nanowire growth
For years, researchers have been trying to find ways to grow an optimal nanowire, using crystals with perfectly aligned layers all along the wire.
Phys.org / Soft tissue makes coral tougher in the face of climate change
Climate change and ocean warming threaten coral reefs and disrupt the harmonious relationship between corals and their symbiotic algae, a process known as "coral bleaching." However, a new study conducted by scientists at ...
