Published Shedding light on the chemical enigma of sulfur trioxide in the atmosphere
(via sciencedaily.com) Original source 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 Finding the beat of collective animal motion
(via sciencedaily.com) Original source Virtual Reality experiments have illuminated the rhythmic glue that could keep animals moving in synchrony.
Published Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought
(via sciencedaily.com) Original source Constantly on the hunt for food: Harbor porpoises more vulnerable than previously thought to the disturbances from humans. The small whales spend more than 60 percent of their day hunting small fish to stay warm in the cold waters. New research shows that harbor porpoises spend little energy on this hunting strategy, but that it makes them vulnerable to human disturbance.
Published Ancient people hunted extinct elephants at Tagua Tagua Lake in Chile 12,000 years ago
(via sciencedaily.com) Original source Thousands of years ago, early hunter-gatherers returned regularly to Tagua Tagua Lake in Chile to hunt ancient elephants and take advantage of other local resources, according to a new study.
Published Chemist developing method to recycle more plastics
(via sciencedaily.com) Original source To improve recycling rates a professor is working on new ways to separate and recycle mixed plastics.
Published Exploring diversity in cell division
(via sciencedaily.com) Original source Animals and fungi predominantly use two different modes of cell division -- called open and closed mitosis, respectively. A new study has shown that different species of Ichthyosporea -- marine protists that are close relatives of both animals and fungi -- use either open and closed mitosis, closely correlated to whether the species has multinucleate life cycle stages. The study demonstrates the way animals do cell division might have evolved long before animals themselves did and how this is linked to an organism's life cycle.
Published How the 'home' environment influences microbial interactions
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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 'Fossilizing' cracks in infrastructure creates sealing that can even survive earthquakes
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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
(via sciencedaily.com) Original source 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.
Published New insights into the degradation dynamics of organic material in the seafloor
(via sciencedaily.com) Original source Many processes in the deep sea are not yet well understood, and the role of microbial communities in particular is often a big unknown. This includes, for example, how organic material that sinks from the water surface to the ocean floor is metabolised -- an important building block for a better understanding of the global carbon cycle.
Published Alaska's rusting waters: Pristine rivers and streams turning orange
(via sciencedaily.com) Original source Dozens of Alaska's rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study.
Published Regional differences in bird diversity in agroforestry systems
(via sciencedaily.com) Original source The diversity and ecological functionality of bird communities in tropical agroforestry systems are shaped by the surrounding landscape, in particular the extent and composition of the forest.
Published Researchers find unique adaptations of fungus associated with bee bread
(via sciencedaily.com) Original source The past attempts of honey bee researchers to inventory the fungal diversity in honey bee colonies revealed that Aspergillus flavus is frequently found in hives. In a new study, researchers have discovered that this fungus is uniquely adapted to survive in bee colonies.
Published Rabies outbreaks in Costa Rica cattle linked to deforestation
(via sciencedaily.com) Original source Deforestation in Costa Rica raises the risk of cattle becoming infected with rabies by vampire bats, finds a new study.
Published Researchers discover hidden step in dinosaur feather evolution
(via sciencedaily.com) Original source Scientists discover 'zoned development' in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers. A new dinosaur skin fossil has been found to be composed of silica -- the same as glass.
Published A rise in sea urchins and related damage to kelp forests impacts Oregon's gray whales and their food
(via sciencedaily.com) Original source A recent boom in the purple sea urchin population off the southern Oregon Coast appears to have had an indirect and negative impact on the gray whales that usually forage in the region, a new study shows.
Published Can coal mines be tapped for rare earth elements?
(via sciencedaily.com) Original source A team of geologists analyzed 3,500 samples taken in and around coal mines in Utah and Colorado. Their findings open the possibility that these mines could see a secondary resource stream in the form of rare earth metals used in renewable energy and numerous other high-tech applications.
Published Meerkat chit-chat
(via sciencedaily.com) Original source Researchers unravel the vocal interactions of meerkat groups and show they use two different types of interactions to stay in touch.
