In a new report now published in Science Advances, Mathias Oster, and a team of scientists at the Institute for Mathematics at the Berlin Institute of Technology and the School of Engineering at the University of Edinburg in the U.K., presented a thr.....»»
Ancient protein structure may have enabled early molecular evolution and diversification
In a finding that offers fresh insights into the early evolution of life on Earth, two RIKEN biologists have conducted lab experiments that have revealed a previously unknown protein fold, which is completely absent in modern proteins......»»
Filament structure found to activate and regulate CRISPR-Cas "protein scissors"
CRISPR-Cas systems help to protect bacteria from viruses. Several different types of CRISPR-Cas defense systems are found in bacteria, which differ in their composition and functions. Among them, the most studied proteins today are Cas9 and Cas12, al.....»»
Developing novel chiral capsule tools for advanced optical technologies
Chirality is an essential property in biology; the molecular building blocks of some of the most important biological structures, including DNA and proteins, are chiral. When a molecule is said to be chiral, it means that it is distinguishable from i.....»»
Ring Protect rebrands to Ring Home and adds 24/7 recording
Ring Protect is now Ring Home, and while its pricing structure is the same, it benefits from several cool new features -- including 24/7 recording......»»
Seeing double: Designing drugs that target "twin" cancer proteins
Some proteins in the human body are easy to block with a drug; they have an obvious spot in their structure where a drug can fit, like a key in a lock. But other proteins are more difficult to target, with no clear drug-binding sites......»»
3D structure of key protein could advance development of hormone-free male contraceptive pill
Melbourne-based scientists behind the development of a hormone-free, reversible male contraceptive pill have, for the first time, solved the molecular structure of the discovery program's primary therapeutic target, significantly increasing the chanc.....»»
Geologists discover mysterious subduction zone beneath Pacific, reshaping understanding of Earth"s interior
University of Maryland scientists uncovered evidence of an ancient seafloor that sank deep into Earth during the age of dinosaurs, challenging existing theories about Earth's interior structure. Located in the East Pacific Rise (a tectonic plate boun.....»»
These 3D-printed pipes inspired by shark intestines outperform Tesla valves
Prototypes control fluid flow in a preferred direction with no need for moving parts. Enlarge / Shark intestines are naturally occurring Tesla valves; scientists have figured out how to mimic their unique structure. (credit: Sara.....»»
OpenAI drops nonprofit status in large-scale reorganization
OpenAI is reportedly planning to scrap the nonprofit structure of its core business in favor of a for-profit model that will be more attractive to investors......»»
How social structure influences the way people share money
People around the globe often depend on informal financial arrangements, borrowing and lending money through social networks. Understanding this sheds light on local economies and helps fight poverty......»»
Researchers uncover key insights into cholesterol"s structure in cell membranes
A new study by Rice University researchers led by Jason Hafner could open new pathways for understanding how cholesterol influences cell membranes and their receptors, paving the way for future research on diseases linked to membrane organization. Th.....»»
Chemists discover new ways in which single-celled organisms organize their DNA
It has only recently been discovered that single-celled organisms (bacteria and archaea) also have histones—proteins that structure DNA. Now, Leiden Ph.D. candidate Samuel Schwab has found that the histones in these organisms are much more diverse.....»»
From chaos to order: Proteins can re-structure themselves to create important substances
The protein "MIPS" changes its internal structure when it becomes active. Its disordered active center becomes a defined structure with special functions. The protein plays a key role in the production of inositol, which is also known as vitamin B8,.....»»
X-Ray Imaging and Spectroscopy Mission unveils black hole and supernova remnant surroundings
The X-Ray Imaging and Spectroscopy Mission (XRISM) has revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific resu.....»»
NASA"s Chandra finds galaxy cluster that crosses the streams
Astronomers using NASA's Chandra X-ray Observatory have found a galaxy cluster has two streams of superheated gas crossing one another. This result shows that crossing the streams may lead to the creation of new structure......»»
Simulated construction of plant-based fish meat with composite structure via 3D printing
To date, about 90% of fish resources worldwide have already reached their sustainable fishery limit. Meanwhile, intensive farming and aquaculture contribute to significant environmental pollution and degradation. To address both the challenges of lim.....»»
Study suggests political ideology is associated with differences in brain structure, but less so than previously thought
Conservative voters have slightly larger amygdalas than progressive voters—by about the size of a sesame seed. In a replication study published September 19 in the journal iScience, researchers revisited the idea that progressive and conservative v.....»»
Physicists reveal evolution of shell structure using machine learning
A research team has used a machine learning approach to investigate the evolution of shell structure for nuclei far from the stability valley. The study, published in Physics Letters B and conducted by researchers from the Institute of Modern Physics.....»»
New method improves understanding of light-wave propagation in anisotropic materials
Understanding how light travels through various materials is essential for many fields, from medical imaging to manufacturing. However, due to their structure, materials often show directional differences in how they scatter light, known as anisotrop.....»»
Bridging large riverine ecosystems for inter-basin exchanges
Many of the world's large rivers have been modified to support food security, hydropower production, navigation and trade. While these developments are necessary to support a growing human population, they also pose substantial risks to the structure.....»»
