Published Fossil frogs share their skincare secrets



Palaeontologists have solved a hundred-year-old mystery of how some fossil frogs preserve their fleshy parts -- it's all down to their skin. Palaeontologists studied 45-million-year-old fossil frogs from the Geiseltal site in central Germany. Remarkably, the fossils show full body outlines of the soft tissues. The team discovered that the excellent condition of the fossil frogs is due to preservation of ancient skin remnants.
Published Compact quantum light processing



An international collaboration of researchers has achieved a significant breakthrough in quantum technology, with the successful demonstration of quantum interference among several single photons using a novel resource-efficient platform. The work represents a notable advancement in optical quantum computing that paves the way for more scalable quantum technologies.
Published Lemur's lament: When one vulnerable species stalks another



What can be done when one threatened animal kills another? Scientists studying critically endangered lemurs in Madagascar confronted this difficult reality when they witnessed attacks on lemurs by another vulnerable species, a carnivore called a fosa.
Published Octopus inspires new suction mechanism for robots



A new robotic suction cup which can grasp rough, curved and heavy stone, has been developed by scientists.
Published Paleontologists unearth what may be the largest known marine reptile



The fossilized remains of a second gigantic jawbone measuring more than two meters long has been found on a beach in Somerset, UK.
Published Study finds iron-rich enamel protects, but doesn't color, rodents' orange-brown incisors



Chattering squirrels, charming coypus, and tail-slapping beavers -- along with some other rodents -- have orange-brown front teeth. Researchers have produced high-resolution images of rodent incisors, providing an atomic-level view of the teeth's ingenious enamel and its coating. They discovered tiny pockets of iron-rich materials in the enamel that form a protective shield for the teeth but, importantly, don't contribute to the orange-brown hue -- new insights that could improve human dentistry.
Published Making crops colorful for easier weeding



To make weeding easier, scientists suggest bioengineering crops to be colorful or to have differently shaped leaves so that they can be more easily distinguished from their wild and weedy counterparts. This could involve altering the crops' genomes so that they express pigments that are already produced by many plants, for example, anthocyanins, which make blueberries blue, or carotenoids, which make carrots orange. Then, they say, weeding robots could be trained to remove only the weeds using machine learning.
Published Older males out-compete young males outside breeding pairs, bird study shows



Young male blue tits are less successful in fathering offspring outside their breeding pair, not because of a lack of experience, but because they are outcompeted by older males, researchers report.
Published Crucial connection for 'quantum internet' made for the first time



Researchers have produced, stored, and retrieved quantum information for the first time, a critical step in quantum networking.
Published Can animals count?



Researchers have made a groundbreaking discovery regarding number sense in animals by confirming the existence of discrete number sense in rats, offering a crucial animal model for investigating the neural basis of numerical ability and disability in humans.
Published Unlocking the 'chain of worms'



An international team of scientists has published a single-cell atlas for Pristina leidyi (Pristina), the water nymph worm, a segmented annelid with extraordinary regenerative abilities that has fascinated biologists for more than a century.
Published Evolution's recipe book: How 'copy paste' errors cooked up the animal kingdom



A series of whole genome and gene duplication events that go back hundreds of millions of years have laid the foundations for tissue-specific gene expression, according to a new study. The 'copy-paste' errors allowed animals to keep one copy of their genome or genes for fundamental functions, while the second copy could be used as raw material for evolutionary innovation. Events like these, at varying degrees of scale, occurred constantly throughout the bilaterian evolutionary tree and enabled traits and behaviours as diverse as insect flight, octopus camouflage and human cognition.
Published Quantum precision: A new kind of resistor



Researchers have developed a method that can improve the performance of quantum resistance standards. It's based on a quantum phenomenon called Quantum Anomalous Hall effect.
Published Even the simplest marine organisms tend to be individualistic



Sport junkie or couch potato? Always on time or often late? The animal kingdom, too, is home to a range of personalities, each with its own lifestyle. Biologists report on a surprising discovery: even simple marine polychaete worms shape their day-to-day lives on the basis of highly individual rhythms. This diversity is of interest not just for the future of species and populations in a changing environment, but also for medicine.
Published Leptanilla voldemort, a ghostly slender new ant species from the dark depths of the underground



In the sun-scorched Pilbara region of north-western Australia, scientists have unearthed a mysterious creature from the shadows -- a new ant species called Leptanilla voldemort.
Published Breakthrough promises secure quantum computing at home



The full power of next-generation quantum computing could soon be harnessed by millions of individuals and companies, thanks to a breakthrough guaranteeing security and privacy. This advance promises to unlock the transformative potential of cloud-based quantum computing.
Published Oxidant pollutant ozone removes mating barriers between fly species



Researchers show that ozone levels, such as those found in many places on hot summer days today, destroy the sex pheromones of fruit fly species. As a result, some natural mating boundaries maintained by species-specific pheromones no longer exist. The research team has shown in experiments that flies of different species mate when exposed to ozone and produce hybrid offspring. Since most of these offspring are unable to reproduce, the results could provide another explanation for the global decline of insects.
Published Quantum breakthrough when light makes materials magnetic



The potential of quantum technology is huge but is today largely limited to the extremely cold environments of laboratories. Now, researchers have succeeded in demonstrating for the very first time how laser light can induce quantum behavior at room temperature -- and make non-magnetic materials magnetic. The breakthrough is expected to pave the way for faster and more energy-efficient computers, information transfer and data storage.
Published New method of measuring qubits promises ease of scalability in a microscopic package



The path to quantum supremacy is made challenging by the issues associated with scaling up the number of qubits. One key problem is the way that qubits are measured. A research group introduces a new approach that tackles these challenges head-on using nanobolometers instead of traditional, bulky parametric amplifiers.
Published 'Teacher Toads' can save native animals from toxic cane toads



Scientists from Macquarie University have come up with an innovative way to stop cane toads killing native wildlife by training goannas to avoid eating the deadly amphibians.
