Phys.org / First direct view tracks planet-forming disk spinning around AB Aurigae
The rotation of a protoplanetary disk (a disk where planets are being formed) has been observed directly for the very first time by mapping the emissions from the dust grains within it. The disk in question surrounds the ...
Phys.org / RNA 'cut-and-patch' tool repairs faulty messages without altering DNA
A research team from the School of Biomedical Sciences at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), has achieved a significant advance in biotechnology that could revolutionize treatment strategies ...
Phys.org / Low-cost method uncovers conical intersections that steer light-driven molecular reactions
Conical intersections are crucial molecular switching points in light-driven reactions, but accurately predicting them usually requires computations. A researcher from Shibaura Institute of Technology has developed a new ...
Phys.org / Matter may entangle with light far more easily near quantum critical points
Quantum entanglement is a state in which particles are entwined with each other. In this entwined state, the properties of one particle influence the other, even when they aren't physically close to each other. This phenomenon ...
Phys.org / Eight metabolic niches reveal how ocean microbes recycle carbon worldwide
The ocean is full of invisible workers. Trillions of microbes quietly break down carbon-containing organic matter, which helps to regulate Earth's climate. But scientists have long struggled to understand how different microbes ...
Phys.org / The Y chromosome is home to surprising jumping genes
The humble Y chromosome may be the smallest chromosome in the mammalian genome (and getting even smaller), but it is mighty: Genes on the Y chromosome are critical for fertility in males. In a new study in the journal Current ...
Dialog / Bridged or not? Scientists uncover a key step in hydrogenase assembly
How does nature build one of the most sophisticated catalytic metal centers found in biology? An international team of researchers has now resolved a long-standing debate surrounding the assembly of the active site of [FeFe]-hydrogenases—enzymes ...
Phys.org / Fast-moving droplets synthesize key drug compounds at room temperature, no catalysts needed
Chemical reactions are the backbone to nearly all biological processes, including those used to make new medicines. However, these reactions can often take considerable time and require harsh conditions or materials—potentially ...
Phys.org / Living brain gene activity revealed noninvasively through programmable blood test
Cell function is determined by how DNA is expressed into proteins. That process includes two main steps—transcription, when messenger RNA (mRNA) makes copies of active genes; and translation, when mRNA guides protein assembly.
Phys.org / Understanding how things connect helps people invent, 1,200-player experiment suggests
Our capacity for innovation, rather than being the work of random variation, is based on an intrinsic understanding of how the world works, claim Karolinska Institutet and Vrije Universiteit Amsterdam researchers in a new ...
Phys.org / From hybrids to 'virgin birth,' stick insects reveal stepwise loss of sex
The evolution of sex remains one of biology's greatest puzzles. While sexual reproduction dominates across the animal kingdom, scientists still debate why it persists despite its high costs. Even more mysterious is the loss ...
Phys.org / Microbes turn biodiesel byproduct into three nylon building blocks, opening greener route
Nylon is a representative plastic material used throughout our daily lives, from clothing to automobiles. However, most of its raw materials have been produced through petrochemical processes, resulting in large carbon emissions. ...
