Published DNA tilts and stretches underlie differences in mutation rates across genomes
(via sciencedaily.com) Original source Researchers have changed the way to look at DNA. They show that DNA is much more than a linear sequence of building blocks; it has a 3D structure that influences the variation of human genome-wide mutation rates meaningfully and consistently, and this is likely conserved among species.
Published Current takes a surprising path in quantum material
(via sciencedaily.com) Researchers used magnetic imaging to obtain the first direct visualization of how electrons flow in a special type of insulator, and by doing so they discovered that the transport current moves through the interior of the material, rather than at the edges, as scientists had long assumed.
Published Unleashing a new era of color tunable nano-devices -- smallest ever light source with switchable colors formed
(via sciencedaily.com) New research has achieved a significant breakthrough in color switching for nanocrystals, unlocking exciting possibilities for a simple, energy efficient display design and for tunable light sources needed in numerous technologies. The discovery also has potential applications in sensitive sensors for various substances, including biological and neuroscience uses, as well as advancements in quantum communication technologies. This nanomaterial breakthrough holds the promise of inspiring exciting innovations in the future.
Published Sensing and controlling microscopic spin density in materials
(via sciencedaily.com) Researchers found a way to tune the spin density in diamond by applying an external laser or microwave beam. The finding could open new possibilities for advanced quantum devices.
Published Nanorings: New building blocks for chemistry
(via sciencedaily.com) Sandwich compounds are special chemical compounds used as basic building blocks in organometallic chemistry. So far, their structure has always been linear. Recently, researchers made stacked sandwich complexes form a nano-sized ring. Physical and other properties of these cyclocene structures will now be further investigated.
Published Researchers are using monkey poop to learn how an endangered species chooses its mates
(via sciencedaily.com) Original source Northern muriquis, which live in the Atlantic forest of Brazil, are one of the most endangered species of monkey in the world. To better understand what goes on in the mating lives of muriquis, researchers turned to the monkeys' poop to help gain insight into how the primates choose their mates.
Published Quantum discovery: Materials can host D-wave effects with F-wave behaviors
(via sciencedaily.com) In a potential boon for quantum computing, physicists have shown that topologically protected quantum states can be entangled with other, highly manipulable quantum states in some electronic materials.
Published The history and future of ancient einkorn wheat Is written in its genes
(via sciencedaily.com) Original source Researchers have sequenced the complete genome for einkorn wheat, the world's first domesticated crop and traced its evolutionary history. The information will help researchers identify genetic traits like tolerance to diseases, drought and heat, and re-introduce those traits to modern bread wheat.
Published Oldest known species of swimming jellyfish identified
(via sciencedaily.com) Original source Royal Ontario Museum announces the oldest swimming jellyfish in the fossil record with the newly named Burgessomedusa phasmiformis. This 505-million-year-old swimming jellyfish from the Burgess Shale highlights diversity in the Cambrian ecosystem.
Published Scientists uncover a surprising connection between number theory and evolutionary genetics
(via sciencedaily.com) An interdisciplinary team of mathematicians, engineers, physicists, and medical scientists has uncovered an unexpected link between pure mathematics and genetics, that reveals key insights into the structure of neutral mutations and the evolution of organisms.
Published Absence of universal topological signatures in high harmonic generation
(via sciencedaily.com) Theoreticians report that they found no evidence of any universal topological signatures after performing the first ab initio investigation of high harmonic generation from topological insulators.
Published When cheating pays -- survival strategy of insect uncovered
(via sciencedaily.com) Original source Researchers have revealed the unique 'cheating' strategy a New Zealand insect has developed to avoid being eaten -- mimicking a highly toxic species.
Published Nuclear spin's impact on biological processes uncovered
(via sciencedaily.com) Researchers have discovered that nuclear spin influences biological processes, challenging long-held beliefs. They found that certain isotopes behave differently in chiral environments, affecting oxygen dynamics and transport. This breakthrough could advance biotechnology, quantum biology, and NMR technology, with potential applications in isotope separation and medical imaging.
Published Researchers find evolutionary adaption in trout of Wyoming's Wind River Mountains
(via sciencedaily.com) Original source Scientists found that trout from lakes stocked decades ago in the Wind River Mountains have higher numbers of gill rakers, which are bony or cartilage structures in the gullets of fish that act as sieves to retain zooplankton and nourish the trout. The difference is likely a result of the trout adapting to the food sources of the once-fishless high-mountain lakes -- a change that has taken place in a relatively short period of time and at a rate that is generally consistent with the historic timing of stocking for each of the lakes.
Published Scientists create novel approach to control energy waves in 4D
(via sciencedaily.com) Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.
Published When electrons slowly vanish during cooling
(via sciencedaily.com) Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature's smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics.
Published Bees evolved from ancient supercontinent, diversified faster than suspected
(via sciencedaily.com) Original source The origin of bees is tens of millions of years older than most previous estimates, a new study shows. A team led by Washington State University researchers traced the bee genealogy back more than 120 million years to an ancient supercontinent, Gondwana, which included today's continents of Africa and South America.
Published Novel Raman technique breaks through 50 years of frustration
(via sciencedaily.com) Researchers have developed a new technique that vastly improves readings of protein-to-ligand interactions through Raman spectroscopy.
Published Mutation accessibility fuels influenza evolution
(via sciencedaily.com) Original source Scientists showed that fixed mutations within a viral population most likely stem from how easy it is to acquire that mutation (i.e., mutation accessibility) rather than just its benefit.
Published How atomic nuclei vibrate
(via sciencedaily.com) Using ultra-high-precision laser spectroscopy on a simple molecule, a group of physicists has measured the wave-like vibration of atomic nuclei with an unprecedented level of precision. The physicists report that they can thus confirm the wave-like movement of nuclear material more precisely that ever before and that they have found no evidence of any deviation from the established force between atomic nuclei.
