Measuring nanocomposite structures with neutron and X-ray scattering
Experiments with state-of-the-art scattering instruments reveal an absence of specific patterns in the X-rays scattered by nanocomposite materials. With the help of advanced simulation techniques, a new study suggests that attractive interactions bet.....»»
New insights in the regulation of genetic information exchange
Within every cell in our body, our DNA is tightly bundled with proteins to form structures known as chromosomes. The commonly known shape of a chromosome relates to an X-shaped appearance in many organisms. The formation of the X-shaped chromosome re.....»»
Team demonstrates fabrication method to construct 3D structures that mimic bone microstructure
Scientists have combined laser 3D printing technology and an alternate soaking process to construct complex 3D structures that mimic bone microstructure. This is the first demonstration of this fabrication method, and it will lead to the development.....»»
Measuring exciton "holes": Insights into charge transfer at atomically thin interfaces between semiconductors
Semiconductors are ubiquitous in modern technology, working to either enable or prevent the flow of electricity. In order to understand the potential of two-dimensional semiconductors for future computer and photovoltaic technologies, researchers fro.....»»
The dynamics of deformable systems: Study unravels mathematical mystery of cable-like structures
Are our bodies solid or liquid? We all know the convention—that solids maintain their shapes, while liquids fill the containers they're in. But often in the real world, those lines are blurred. Imagine walking on a beach. Sometimes the sand gives w.....»»
Rocket Report: US military still wants point-to-point; India’s big 2024 ambitions

Trained AI system learns to design cellular materials for tissue engineering, energy storage
Artificial structures called cellular materials have a network of internal spaces within a solid cell-like matrix. Their porous foam-like architecture combines advantages of low density with strength. Researchers at the National Institute for Materia.....»»
Examining how molecular orbitals determine stability
Carboxylic acid dianions (fumarate, maleate, and succinate) play a role in coordination chemistry and, to some extent, also in the biochemistry of body cells. An HZB team at BESSY II has now analyzed their electronic structures using RIXS in combinat.....»»
Scientists reveal why blueberries are blue
Tiny external structures in the wax coating of blueberries give them their blue color, researchers at the University of Bristol can reveal. This applies to a lot of fruits that are the same color including damsons, sloes and juniper berries......»»
Building a DNA nanoparticle to be both carrier and medicine
Scientists have been making nanoparticles out of DNA strands for two decades, manipulating the bonds that maintain DNA's double-helical shape to sculpt self-assembling structures that could someday have jaw-dropping medical applications......»»
New research finds that young planets are flattened structures rather than spherical
Astrophysicists from the University of Central Lancashire (UCLan) have found that planets have flattened shapes like smarties just after they form rather than being spherical as previously thought......»»
Exploring new physics arising from electron interactions in semiconductor moiré superlattices
Semiconductor moiré superlattices are fascinating material structures that have been found to be promising for studying correlated electron states and quantum physics phenomena. These structures, made up of artificial atom arrays arranged in a so-ca.....»»
Our oldest microbial ancestors were way ahead of their time
Specialized internal structures were present over 1.5 billion years ago. Enlarge / The Golgi apparatus, shown here in light green, may have been involved in building internal structures in cells. (credit: ARTUR PLAWGO / SCIENCE P.....»»
Mathematicians finally solved Feynman’s “reverse sprinkler” problem
We might not need to "unwater" our lawns, but results could help control fluid flows. Light-scattering microparticles reveal the flow pattern for the reverse (sucking) mode of a sprinkler, showing vortices and complex f.....»»
Nondestructive technique for identifying nuclides using neutron resonance transmission analysis
A feasibility study conducted at CSNS Back-n facility, recently published in Nuclear Science and Techniques, demonstrates a significant prospect of NRTA in nondestructive nuclide identification......»»
A new kink in proton spectrum to enhance our knowledge of cosmic ray origin
The GRAPES-3 experiment in Ooty, India, operated by the Tata Institute of Fundamental Research has discovered a new feature in the cosmic-ray proton spectrum at about 166 tera-electron-volt (TeV) energy while measuring the spectrum spanning from 50 T.....»»
How the social structures of Nazi Germany created a bystander society
In the initial post-war judicial proceedings to establish what had happened under Nazism, and to punish the perpetrators of crimes, victims' accounts were often discredited. Only in 1961, with the high-profile trial of Nazi war criminal Adolf Eichman.....»»
"Flawed" material resolves superconductor conundrum
Christopher Parzyck had done everything right. Parzyck, a postdoctoral researcher, had brought his nickelate samples—a newly discovered family of superconductors—to a synchrotron beamline for X-ray scattering experiments. He was measuring his sam.....»»
Gene expression influences 3D folding of chromosomes by altering structure of the DNA helix, finds study
A collaborative study by the UTokyo-KI LINK program, headed by Camilla Björkegren from Karolinska Institutet, Kristian Jeppsson and Katsuhiko Shirahige from The University of Tokyo shows that a protein complex named Smc5/6 binds DNA structures calle.....»»
Structural color ink: Printable, non-iridescent and lightweight
