Phys.org / Data-driven 3D chromosome model reveals structural and dynamic features of DNA
Chromosomes are masters of organization. These long strings of DNA fold down into an ensemble of compact structures that keep needed parts of the genome accessible while tucking away those that aren't used as often. Understanding ...
Phys.org / Red flowers have a 'magic trait' to attract birds and keep bees away
For flowering plants, reproduction is a question of the birds and the bees. Attracting the right pollinator can be a matter of survival—and new research shows how flowers do it is more intriguing than anyone realized, and ...
Phys.org / Hafted stone tools in China suggest early hominins were more inventive than thought
A newly excavated archaeological site in central China is reshaping long-held assumptions about early hominin behavior in Eastern Asia. Led by the Chinese Academy of Sciences, an international team of researchers conducted ...
Phys.org / 'Spectral slimming' yields ultranarrow plasmons in single metal nanoparticles
Researchers have developed a new strategy to overcome a long-standing limitation in plasmonic loss by reshaping light–matter interactions through substrate engineering.
Phys.org / Streaks on Mercury show that it is not a 'dead planet'
Although Mercury was geologically active in its early days, today its surface appears almost completely static. This is why it is often perceived as a dead and dry planet. A new study led by Dr. Valentin Bickel from the Center ...
Phys.org / How defects make permanent magnets even more efficient
Rare-earth magnets are essential for electric motors in vehicles, drones, and trains, forming the backbone of modern, environmentally friendly mobility. These are not simple blocks of metal, but carefully engineered materials ...
Phys.org / First radio signals from rare supernova reveal star's final years
Astronomers have captured the first radio waves ever detected from a rare class of exploding star, a discovery that has given them an unprecedented look into the final years of a massive star before its death in a powerful ...
Phys.org / Raman sensors with push-pull alkyne tags amplify weak signals to track cell chemistry
Seeing chemistry unfold inside living cells is one of the biggest challenges of modern bioimaging. Raman microscopy offers a powerful way to meet this challenge by reading the unique vibrational signatures of molecules. However, ...
Phys.org / Showing real climate wins and friendships helps people join collective climate efforts
What does it take to spur individuals to act as a group with a shared purpose on climate change? According to a new Stanford-led study, the key is to show them how collective actions on climate have made a difference and ...
Phys.org / A new route to synthesize multiple functionalized carbon nanohoops
The field of nanomaterials is witnessing a transformative shift at the intersection of organic chemistry and molecular engineering. Among the most promising molecular structures are carbon nanohoops, of which [n]cycloparaphenylenes ...
Phys.org / Net-casting spiders' adjustable silk stiffness point to tunable fiber design
What makes spider silk so extraordinarily strong and elastic at the same time? This was the focus of recent investigations carried out by researchers from the University of Greifswald, the University of Bonn and the Museum ...
Phys.org / Twisted oxide crystals show how atomic patterns alone can trap or repel electrons
It has been revealed that simply twisting and stacking two layers of oxide crystals can allow the atomic arrangement itself to control the behavior of electrons. Much like the new patterns that emerge when two meshes are ...
