Phys.org / Electrochemical signals can reshape bacterial protein patterns, boosting electron transfer
Sometimes, transporting electrons from one cell to another is a team effort. In electroactive bacteria, that team is a group of proteins that shepherds electrons forward, passing them along like a relay baton, so they can ...
Phys.org / Ultrafast X-rays reveal physical principles behind lipoprotein motion within egg yolk plasma
Egg yolk may appear runny and uniform, but on the nanoscale, it is one of the most crowded biological fluids in nature. Packed with proteins and fats, it serves as a dense storage reservoir for a developing embryo. Yet the ...
Phys.org / Why laws named after tragedies win public support
When lawmakers name bills after victims of tragedy—such as Megan's Law or the Brady Handgun Violence Prevention Act of 1993—public support surges, but this emotional boost may come at the expense of sound policymaking, ...
Phys.org / Phosphoric acid dimers reveal nature's proton highway
Whether in our bodies or in fuel cells, phosphoric acid plays an important role in many chemical processes because it is exceptionally good at transporting charges. Researchers from the Department of Molecular Physics at ...
Phys.org / Courtship is complicated, even in fruit flies
Love is in the air for the vinegar fly. Drosophila melanogaster has long been a model for understanding how brains translate sensory information into courtship behavior. Male flies perform a multitude of romantic actions—orienting, ...
Phys.org / Extreme heat waves trigger unexpected nanoparticle formation in air
Tiny aerosol particles in the air play a big role in regulating how much sunlight our planet absorbs or reflects, and how clouds form above us. In a recent study, researchers found that extreme heat waves can trigger new ...
Phys.org / 5,000-year-old bureaucracy: Over 7,000 prehistoric seal impressions uncovered in western Iran
In the journal Antiquity, Dr. Shokouh Khosravi published preliminary findings of the largest known corpus of prehistoric seal impressions in the entire ancient world. The corpus, made up of over 7,000 seal impressions, more ...
Phys.org / Quantum reservoir computing peaks at the edge of many-body chaos, study suggests
Reservoir computing is a promising machine learning-based approach for the analysis of data that changes over time, such as weather patterns, recorded speech or stock market trends. Classical reservoir computing techniques ...
Phys.org / Language barriers slow down the international diffusion of knowledge, study finds
Rapid technological and scientific advances have fueled a huge wave of innovation over the past decades. The speed of global innovation is known to be dependent on the exchange of knowledge and skills between different nations ...
Phys.org / Sunray-like ripples emerge on a frozen reaction front
Researchers in Belgium have unveiled a striking chemical reaction in which ripples along a frozen reaction front resemble the rays of a shining star. Publishing their results in Physical Review Letters, Anne De Wit and colleagues ...
Phys.org / How to improve the performance of qubits: Super-fast fluctuation detection achieved
Using commercially available technology and innovative methods, researchers at NBI have pushed the limits of how fast you can detect changes in the sensitive quantum states in the qubit. Their work allows researchers to follow ...
Phys.org / In sea urchin and salmon sperm, pH value regulates whether they remain immotile or swim
A study by the Max Planck Institute for Multidisciplinary Sciences and the University of Bonn has shown that pH value is crucial for sperm motility in sea urchins and salmon. An increase in pH activates the enzyme adenylyl ...
