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 Fusion model hot off the wall
(via sciencedaily.com) Heat load mitigation is critical to extending the lifetime of future fusion device. Researchers have found a way to explain the rotational temperatures measured in three different experimental fusion devices in Japan and the United States. Their model evaluates the surface interactions and electron-proton collisions of hydrogen molecules.
Published A non-covalent bonding experience
(via sciencedaily.com) Putting a suite of new materials synthesis and characterization methods to the test, a team of scientists has developed 14 organic-inorganic hybrid materials, seven of which are entirely new.
Published Unlocking the power of molecular crystals: A possible solution to nuclear waste
(via sciencedaily.com) A team researchers has discovered molecular crystals capable of capturing iodine -- one of the most common radioactive fission products -- and other pollutants. The versatile crystals could be used for nuclear waste management and other energy-related applications and move the world closer to a net-zero future.
Published Flying reptiles had nurturing parental style
(via sciencedaily.com) Original source Did the pterosaurs, flying reptiles from the days of the dinosaurs, practice parental care or not? New research shows that pterosaurs were indeed caring parents -- but only the larger species.
Published 'Stunning' discovery: Metals can heal themselves
(via sciencedaily.com) Original source Researchers announce the first observation of a self-healing metal. If harnessed, the newly discovered phenomenon could someday lead to engines, bridges and airplanes that reverse damage caused by wear and tear, making them safer and longer-lasting.
Published Unusual fossil shows rare evidence of a mammal attacking a dinosaur
(via sciencedaily.com) Original source Scientists have described an unusual fossil from around 125 million years ago in China that shows a dramatic moment in time when a carnivorous mammal attacked a larger plant-eating dinosaur. The two animals are locked in mortal combat, and it's among the first evidence to show actual predatory behavior by a mammal on a dinosaur. The fossil's presence challenges the view that dinosaurs had few threats from their mammal contemporaries during the Cretaceous, when dinosaurs were the dominant animals.
Published Search for dark matter
(via sciencedaily.com) Original source Scientists have applied a promising new method to search for dark matter particles in a particle accelerator. The method is based on the observation of the spin polarization of a particle beam in a storage ring COSY.
Published Ice Age saber-tooth cats and dire wolves suffered from diseased joints
(via sciencedaily.com) Original source Ice Age saber-tooth cats and dire wolves experienced a high incidence of bone disease in their joints, according to new research.
Published Tiny scales reveal megalodon was not as fast as believed, but it had a mega-appetite explaining its gigantism
(via sciencedaily.com) Original source A new study reveals the iconic extinct Megalodon, or 'megatooth shark', was a rather slow cruiser that used its warm-bloodedness to facilitate digestion and absorption of nutrients.
Published Evolutionary origins of the pygmy right whale
(via sciencedaily.com) Original source Researchers have finally settled a decades-long dispute about the evolutionary origins of the pygmy right whale.
Published Public support hydrogen and biofuels to decarbonize global shipping
(via sciencedaily.com) Original source New research into public attitudes towards alternative shipping fuels shows public backing for biofuel and hydrogen. The study also found that nuclear was preferred to the heavy fuel oil (HFO) currently used in the global shipping industry, although both were perceived negatively. Ammonia had the least public support.
Published Fossils reveal how ancient birds molted their feathers -- which could help explain why ancestors of modern birds survived when all the other dinosaurs died
(via sciencedaily.com) Original source Birds are the only group of dinosaurs that survived the asteroid-induced mass extinction 66 million years ago. But not all the birds alive at the time made it. Why the ancestors of modern birds lived while so many of their relatives died has been a mystery that paleontologists have been trying to solve for decades. Two new studies point to one possible factor: the differences between how modern birds and their ancient cousins molt their feathers.
Published A jaw-dropping conundrum: Why do mammals have a stiff lower jaw?
(via sciencedaily.com) Original source The lower jaws of lizards, birds, fish and even dinosaurs are comprised of multiple bones per side. Yet mammals diverged from all other vertebrates and settled on just one bone, repurposing the extra bones into a more elaborate inner ear, perhaps the better to hear. The single bone per side, fused in primates into one jawbone, makes the jaw more rigid. A paleontologist asks, Did the stiffer, rigid jaw make mammals more successful?
Published New driver for shapes of small quark-gluon plasma drops?
(via sciencedaily.com) Original source New measurements of how particles flow from collisions of different types of particles at the Relativistic Heavy Ion Collider (RHIC) have provided new insights into the origin of the shape of hot specks of matter generated in these collisions. The results may lead to a deeper understanding of the properties and dynamics of this form of matter, known as a quark-gluon plasma (QGP).
Published Humans' ancestors survived the asteroid impact that killed the dinosaurs
(via sciencedaily.com) Original source A Cretaceous origin for placental mammals, the group that includes humans, dogs and bats, has been revealed by in-depth analysis of the fossil record, showing they co-existed with dinosaurs for a short time before the dinosaurs went extinct.
Published Megalodon was no cold-blooded killer
(via sciencedaily.com) Original source How the megalodon, a shark that went extinct 3.6 million years ago, stayed warm was a matter of speculation among scientists. Using an analysis of tooth fossils from the megalodon and other sharks of the same period, a study suggests the animal was able to maintain a body temperature well above the temperature of the water in which it lived. The finding could help explain why the megalodon went extinct during the Pliocene Epoch.
Published Extinct warbler's genome sequenced from museum specimens
(via sciencedaily.com) Original source The Bachman's warbler, a songbird that was last seen in North America nearly 40 years ago, was a distinct species and not a hybrid of its two living sister species, according a new study in which the full genomes of seven museum specimens of the bird were sequenced.
Published To boost supply chains, scientists are looking at ways to recover valuable materials from water
(via sciencedaily.com) Original source Researchers are exploring the different ways of harvesting materials from water.
Published Lost giants: New study reveals the abundance decline of African megafauna
(via sciencedaily.com) Original source A groundbreaking new paper focuses on the size and abundance of living and fossil African large mammals, shedding light on the ecological dynamics behind the decline of these iconic creatures. The findings challenge previous assumptions about the causes of megafaunal extinctions in Africa and provide new insights into the restructuring of ecosystems over millions of years.
