Phys.org / Seeing inside smart gels: Scientists capture dynamic behavior under stress
Advances in materials science have led to the development of "smart materials," whose properties do not remain static but change in response to external stimuli. One such material is poly(N-isopropylacrylamide), or PNIPAM, ...
Phys.org / Fullerenes could improve MRI clarity by enabling more efficient dynamic nuclear polarization
Magnetic resonance imaging (MRI) is invaluable in the medical world. But despite all the good it does, there is room for improvement. One way to enhance the sensitivity of MRI is dynamic nuclear polarization (DNP), where ...
Phys.org / Receptor with 'rubber band' paves way for new pain and cancer drugs
The human P2X4 receptor plays an important role in chronic pain, inflammation and some types of cancer. Researchers at the University of Bonn and the University Hospital Bonn (UKB) have now discovered a mechanism that can ...
Phys.org / New molecular view of cholera 'tail' could inform better treatment
Cholera is a deadly bacterial disease that kills about 95,000 people every year. Vibrio cholerae bacteria infect cells in the small intestine, which the bacteria can do in part due to their flagella—powerful tail-like structures ...
Phys.org / C-Compass: AI-based software maps proteins and lipids within cells
A new tool developed by Helmholtz Munich and the German Center for Diabetes Research and the University of Bonn makes spatial proteomics and lipidomics easier to use—no coding required. C-COMPASS allows scientists to profile ...
Phys.org / From static papers to living models: Turning limb development research into interactive science
The choreographed movements that cells perform to form complex biological shapes, like our hands, have fascinated scientists for centuries. Now, researchers at EMBL Barcelona have launched LimbNET, an open-access online platform ...
Phys.org / How Ramanujan's formulae for pi connect to modern high energy physics
Most of us first hear about the irrational number π (pi)—rounded off as 3.14, with an infinite number of decimal digits—in school, where we learn about its use in the context of a circle. More recently, scientists have ...
Phys.org / Over 16,000 dinosaur footprints identified along a Bolivian shoreline
A fossil site in Bolivia preserves thousands of traces of dinosaurs who walked, ran, and swam along an ancient coastline, according to a study by Raúl Esperante of the Geoscience Research Institute, California, U.S., and ...
Phys.org / 10-thousand-year-old genomes from southern Africa change picture of human evolution
In southern Africa, a group of people lived in partial isolation for hundreds of thousands of years. This is shown in a new study based on analyses of the genomes of 28 people who lived between 10,200 and 150 years ago in ...
Phys.org / Free climbers discover remnants of ancient sea turtle stampede in Italy
Rocks have been found to hold many traces of Earth's ancient history, but usually geologists have to seek them out. Every once in a while, however, these imprints of times past are found by unsuspecting visitors. This occurred ...
Phys.org / Astronomers find vast spinning filament of galaxies 140 million light-years away
An international team led by the University of Oxford has identified one of the largest rotating structures ever reported: a "razor-thin" string of galaxies embedded in a giant spinning cosmic filament, 140 million light-years ...
Phys.org / Interstellar object covered in 'icy volcanoes' could rewrite our understanding of how comets formed
Analysis of the second confirmed interstellar comet to visit our solar system suggests that the alien body could be covered in erupting icy, volcano-like structures called cryovolcanoes. Researchers also discovered that the ...
