Polarized neutron scattering reveals preferred spin excitations in bilayer iron-based superconductor
In unconventional superconductors, the major challenge on the mechanism research is to reveal how the electrons form to Cooper pairs and collectively condense to a superconducting state under both interactions from charge and spin. The iron-based sup.....»»
Tiny jumping genes fingered as culprit in rise of antibiotic resistance
Biomedical engineers at Duke University believe they have discovered the physical mechanism that causes high doses of antibiotics to promote the spread of antibiotic resistance between bacteria......»»
The mechanism of trichome formation in response to stress-induced jasmonic acid signaling in tomatoes
As a plant stress hormone, jasmonic acid (JA) plays an important role in mediating the resistance of plants against mechanical stress, pest attack, and pathogenic infection. The biosynthesis of JA and the expression of JA signaling genes are activa.....»»
Water helps in the unexpected and ultrafast synthesis of collagen-like synthetic poly-L-proline
In work published online recently in National Science Review, a team led by Prof. Hua Lu from the College of Chemistry and Molecular Engineering of Peking University reported a surprising finding. In the process of studying the ROP of ProNCA, a type.....»»
A New Proposal For Interstellar Communication With Alien Intelligences
OneHundredAndTen writes: A recent paper proposes a new way to put together a message for alien intelligent beings. It comes up with an elaborate mechanism to convey information in notably constrained bitmaps, but one can't help but wonder whether it.....»»
Quantum "shock absorbers" allow perovskite to exhibit superfluorescence at room temperature
Semiconducting perovskites that exhibit superfluorescence at room temperature do so due to built-in thermal "shock absorbers" which protect dipoles within the material from thermal interference. A new study from North Carolina State University explor.....»»
Octopus-like tentacles help cancer cells invade the body
With help from the best tweezers in the world, a team of researchers from the University of Copenhagen has shed new light on a fundamental mechanism in all living cells that helps them explore their surroundings and even invade tissue. Their discover.....»»
Cu+ doping enhances self-trapped exciton emission in alloyed Cs2(Ag/Na)InCl6 double perovskite
All-inorganic 3D lead-free double perovskites (DPs) with broadband self-trapped exciton (STE) emission have shown great promise as alternatives to lead halide perovskites in various optoelectronic applications such as light-emitting diodes (LEDs) and.....»»
Peering into precise ultrafast dynamics in matter
A team of researchers from Beijing led by Prof. Dr. Sheng Meng has succeeded in developing predictive first-principles approaches for investigating precise ultrafast processes in matter. The method, named TDAP (time-dependent ab initio propagation).....»»
Study provides clues on why some bad infections persist
A new study led by researchers at University of Utah Health details a novel mechanism that infectious bacteria use to quickly adjust to environmental stress. The discovery could help explain why certain types of common infections—such as urinary tr.....»»
Researchers reveal degradation mechanism of non-precious metal catalysts for fuel cells
The development of efficient non-precious metal catalysts (NPMCs) can help reduce the cost of fuel cells and accelerate their commercialization......»»
Industry watch: Success comes slower than expected, growth faster
DIGITIMES started under the critical moment of the Asian financial crisis in 1998, during which Taiwan survived with its abundant foreign exchange reserves and relatively conservative financial management mechanism......»»
Microbial communities where cells cooperate have increased drug tolerance
Research from the Francis Crick Institute has revealed a key mechanism which increases tolerance to drugs amongst microbial communities. The findings could help the development of more effective antifungal treatments......»»
How the mechanism of photoionization can provide insights into complex molecular potentials
How can researchers use the mechanism of photoionization to gain insight into complex molecular potential? This question has now been answered by a team led by Prof. Dr. Giuseppe Sansone from the Institute of Physics at the University of Freiburg. Th.....»»
New research reveals clues to how antibodies become fine-tuned to fight infection
Researchers at the University of Alberta have uncovered new information about a cellular mechanism in the immune system that provides a critical step toward better understanding how antibodies evolve and improve in the human body......»»
Scientists uncover simple strategies for keeping foams on walls
Researchers from Tokyo Metropolitan University have uncovered a unique mechanism by which foams on walls drain and slip over time. They showed how a foam can lose liquid via "pinch-off," like droplets from a faucet, finding that the amount of liquid.....»»
Scientists propose a new mechanism by which oxygen may have first built up in the atmosphere
For the first 2 billion years of Earth's history, there was barely any oxygen in the air. While some microbes were photosynthesizing by the latter part of this period, oxygen had not yet accumulated at levels that would impact the global biosphere......»»
