Scientists at the National Institute of Standards and Technology have now unveiled the long-mysterious inner workings of these semiconductor elements, which can act like the short-term memory of nerve cells.
Scientists at the Technical University of Munich (TUM) have developed a novel electric propulsion technology for nanorobots. It allows molecular machines to move a hundred thousand times faster than with the biochemical processes used to date. This makes nanobots fast enough to do assembly line work in molecular factories. The new research results will appear as the cover story on 19th January in the renowned scientific journal Science.
In cooperation with colleagues from the Wyss Institute at Harvard, researchers from the Julius Wolff Institute, the Berlin-Brandenburg Center for Regenerative Therapies, and Charité's Center for Musculoskeletal Surgery have shown how mechanically optimized constructs known as titanium-mesh scaffolds help optimize bone regeneration. The researchers' findings have been reported in the current issue of Science Translational Medicine.
In cells, proteins tightly package the long thread of DNA into pearl necklace-like complexes known as chromatin. Scientists at EPFL show for the first time how chromatin moves, answering longstanding questions about how its structure helps regulate gene expression. The study is published in Nature Communications.
A new study led by Danielle Bassett at The University of Pennsylvania's School of Engineering and Applied Science is the first to convert the entire human body's network of bones and muscles into a comprehensive mathematical model. A study of the network is publishing on Jan. 18 in the open-access journal PLOS Biology.
By powering a DNA nanorobotic arm with electric fields, scientists have achieved precise nano-scale movement that is at least five orders of magnitude faster than previously reported for DNA-driven robotic systems.
For the first time, scientists can see in minute-time resolution how cells package chromosomes into highly condensed structures prior to cell division.
Researchers have developed the first instrument that can provide a detailed image of the entire eye that can produce higher quality images than currently available.
A new study led by researchers at Indiana University and Rutgers University provides the strongest evidence yet that nearly imperceptible changes in how people move can be used to diagnose neurodevelopmental disorders, including autism.
A small group of fishes -- possibly the world's cleverest carnivorous grazers -- feeds on the scales of other fish in the tropics. A team led by biologists at the University of Washington is trying to understand these scale-feeding fish and how this odd diet influences their body evolution and behavior.
