Published Entomologist sheds light on 250-year-old mystery of the German cockroach



Entomologists have solved the 250-year-old origin puzzle of the most prevalent indoor urban pest insect on the planet: the German cockroach. The team's research findings, representing the genomic analyses of over 280 specimens from 17 countries and six continents, show that this species evolved some 2,100 years ago from an outdoor-living species in Asia.
Published Controlling water, transforming greenhouse gases



Researchers have outlined a way to manipulate water molecules to make CO2R more efficient, with the ultimate goal of creating a clean energy loop. Through their new method, the team was able to perform CO2R with nearly 100% efficiency under mildly acidic conditions, using either gold or zinc as catalysts.
Published Caterpillars can detect their predators by the static electricity they emit



Caterpillars respond defensively to electric fields similar to those emitted by their natural predators, scientists have found.
Published Developing novel methods to detect antibiotics in vegetables and earthworms



Researchers have managed to analyze, simultaneously, several families of antibiotics in vegetables and earthworms. Sampling carried out in various locations has yielded data on the existence of antimicrobial agents and their derivatives in vegetables. In this respect, Vergara stresses the need for further research to address the problem of contamination by this type of medication in the environment.
Published Key role of plant-bacteria communication for the assembly of a healthy plant microbiome supporting sustainable plant nutrition



In an interdisciplinary study, researchers discovered that symbiotic bacteria communicate with legume plants through specific molecules and that this communication influences which bacteria grow near the plant roots. The findings provide insights into how plants and soil bacteria form beneficial partnerships for nutrient uptake and resilience. These results are a step towards understanding how communication between plants and soil bacteria can lead to specific beneficial associations providing plants with nutrients.
Published Psychedelic drug-induced hyperconnectivity in the brain helps clarify altered subjective experiences



A new study shows that the use of psilocybin, a compound found in the widely known 'magic mushrooms,' initiates a pattern of hyperconnectivity in the brain linked to the ego-modifying effects and feelings of oceanic boundlessness. The findings help explain the so-called mystical experiences people report during the use of psychedelics and are pertinent to the psychotherapeutic applications of psychedelic drugs to treat psychiatric disorders such as depression.
Published Charting a pathway to next-gen biofuels



From soil to sequestration, researchers have modeled what a supply chain for second-generation biofuels might look like in the midwestern United States.
Published Iron could be key to less expensive, greener lithium-ion batteries, research finds



Chemistry researchers are hoping to spark a green battery revolution by showing that iron instead of cobalt and nickel can be used as a cathode material in lithium-ion batteries.
Published Shedding light on the chemical enigma of sulfur trioxide in the atmosphere



Researchers discovered that sulfur trioxide can form products other than sulfuric acid in the atmosphere by interacting with organic and inorganic acids. These previously uncharacterized acid sulfuric anhydride products are almost certainly key contributors to atmospheric new particle formation and a way to efficiently incorporate carboxylic acids into atmospheric nanoparticles. Better prediction of aerosol formation can help curb air pollution and reduce uncertainties concerning climate change.
Published Bigger is better: Male proboscis monkeys' enhanced noses evolved to attract mates



When it comes to the animal kingdom, bigger is better. Well, at least for proboscis monkeys, famously known for their long, large and droopy noses. Researchers have provided a world-first explanation for why male proboscis monkeys have larger and 'enhanced' nasal structures.
Published Foraging ants navigate more efficiently when given energy-drink-like doses of caffeine



Ants who receive a caffeine-laced sugary reward become more efficient at navigating back to the reward's location compared to ants that only receive sugar. Caffeinated ants move toward the reward via a more direct path but do not increase their speed, suggesting that caffeine improved their ability to learn. The study was conducted on Argentine ants (Linepithema humile), a globally invasive species, and the researchers say that incorporating caffeine into ant baits could aid efforts to control the ants by improving bait uptake.
Published Sexual parasitism helped anglerfish invade the deep sea during a time of global warming



Members of the vertebrate group including anglerfishes are unique in possessing a characteristic known as sexual parasitism, in which males temporarily attach or permanently fuse with females to mate. Now, researchers show that sexual parasitism arose during a time of major global warming and rapid transition for anglerfishes from the ocean floor to the deep, open sea.
Published Chemist developing method to recycle more plastics



To improve recycling rates a professor is working on new ways to separate and recycle mixed plastics.
Published Australian study proves 'humans are planet's most frightening predator'



A new study demonstrates that kangaroos, wallabies and other Australian marsupials fear humans far more than any other predator.
Published How the 'home' environment influences microbial interactions



A new study shows that real-world ocean conditions make a huge difference in how viral infection affects host bacteria. The findings indicate it is very important to study cells and virocells under nutrient conditions that more closely resemble what they encounter in nature.
Published Promethium bound: Rare earth element's secrets exposed



Scientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.
Published New AI accurately predicts fly behavior



Researchers trained an AI model to accurately predict male fruit flies' courtship behavior in response to any sight of a female. This breakthrough offers new insight into how the brain processes visual data and may someday pave the way for artificial vision technology.
Published 'Fossilizing' cracks in infrastructure creates sealing that can even survive earthquakes



In a new study, a team of researchers used research on fossilizing techniques to create a new method for sealing cracks and fractures in rocks and bedrock using a 'concretion-forming resin'. This innovative technique has applications in a wide range of industries, from tunnel construction to long-term underground storage of hazardous materials.
Published New polystyrene recycling process could be world's first to be both economical and energy-efficient



Engineers have modeled a new way to recycle polystyrene that could become the first viable way of making the material reusable.
Published Cuddled cows who work as therapy animals showed a strong preference for women compared to men, study finds



A new study reveals that cows who are cuddled as therapy animals showed a strong preference for interactions with women when compared to men. In turn, the research, which opens a new era on whether some therapies may be initially stronger based upon gender and not procedure, highlighted that the women also reported greater attachment behaviors towards the steers.
