Published How food availability could catalyze cultural transmission in wild orangutans
(via sciencedaily.com) Original source The proverb "necessity is the mother of invention" has been used to describe the source from which our cultural evolution springs. After all, need in times of scarcity has forced humans to continually invent new technologies that have driven the remarkable cumulative culture of our species. But an invention only becomes cultural if it is learned and spread by many individuals. In other words, the invention must be socially transmitted. But what are the forces that drive social transmission?
Published Ultra-sensitive lead detector could significantly improve water quality monitoring
(via sciencedaily.com) Original source Engineers have developed an ultra-sensitive sensor made with graphene that can detect extraordinarily low concentrations of lead ions in water. The device achieves a record limit of detection of lead down to the femtomolar range, which is one million times more sensitive than previous technologies.
Published Plant groupings in drylands support ecosystem resilience
(via sciencedaily.com) Original source Many complex systems, from microbial communities to mussel beds to drylands, display striking self-organized clusters. According to theoretical models, these groupings play an important role in how an ecosystem works and its ability to respond to environmental changes. A new article focused on the spatial patterns found in drylands offers important empirical evidence validating the models.
Published Scammed! Animals 'led by the nose' to leave plants alone
(via sciencedaily.com) Original source Fake news works for wallabies and elephants. Herbivores can cause substantial damage to crops or endangered or protected plants, with traditional methods to deter foraging lethal, expensive or ineffective. Biologists are now using aromas from plants naturally repellent with remarkable success to deter the animals.
Published Key dynamics of 2D nanomaterials: View to larger-scale production
(via sciencedaily.com) Original source A team of researchers mapped out how flecks of 2D materials move in liquid -- knowledge that could help scientists assemble macroscopic-scale materials with the same useful properties as their 2D counterparts.
Published Discovery of a third RNA virus linage in extreme environments Jan 17, 2024
(via sciencedaily.com) Original source A research group has discovered a novel RNA viral genome from microbes inhabiting a high-temperature acidic hot spring. Their study shows that RNA viruses can live in high-temperature environments (70-80 degrees Celsius), where no RNA viruses have been observed before. In addition to the two known RNA virus kingdoms, a third kingdom may exist.
Published Machine learning guides carbon nanotechnology
(via sciencedaily.com) Original source Carbon nanostructures could become easier to design and synthesize thanks to a machine learning method that predicts how they grow on metal surfaces. The new approach will make it easier to exploit the unique chemical versatility of carbon nanotechnology.
Published Coal-based product could replace sand in concrete
(via sciencedaily.com) Original source A new study found that graphene derived from metallurgical coke, a coal-based product, through flash Joule heating could serve not only as a reinforcing additive in cement but also as a replacement for sand in concrete.
Published Diverse forests are best at standing up to storms
(via sciencedaily.com) Original source European forests with a greater diversity of tree species are more resilient to storms, according to new research.
Published Microplastics may be accumulating rapidly in endangered Galápagos penguins' food web
(via sciencedaily.com) Original source Model predictions showed a rapid increase in microplastic accumulation and contamination across the penguins' prey organisms resulting in Galapagos penguin showing the highest level of microplastics per biomass, followed by barracuda, anchovy, sardine, herring, and predatory zooplankton.
Published Researchers add a 'twist' to classical material design
(via sciencedaily.com) Original source Researchers grew a twisted multilayer crystal structure for the first time and measured the structure's key properties. The twisted structure could help researchers develop next-generation materials for solar cells, quantum computers, lasers and other devices.
Published The complexity of forests cannot be explained by simple mathematical rules, study finds
(via sciencedaily.com) Original source The way trees grow together do not resemble how branches grow on a single tree, scientists have discovered.
Published A new perspective on the temperature inside tropical forests
(via sciencedaily.com) Original source New worldwide maps of temperatures inside tropical forests show that global warming affect different way in different parts of the forests. Undergrowth level temperature of the tropical forests can be even 4 degrees less than average temperature of the area.
Published Wolves and elk are (mostly) welcome back in Poland and Germany's Oder Delta region, survey shows
(via sciencedaily.com) Original source An online survey conducted in Germany and Poland shows that large parts of the participants support the return of large carnivores and herbivores, such as wolves and elk, to the Oder Delta region. Presented with different rewilding scenarios, the majority of survey participants showed a preference for land management that leads to the comeback of nature to the most natural state possible. Locals, on the other hand, showed some reservations.
Published Translating nuclear waste site data into microbial ecosystem insights
(via sciencedaily.com) Original source A flagship seven-year study that explores how environmental stresses influence different ecological processes shaping the composition and structure of microbial communities in groundwater has now been published.
Published Long live the graphene valley state
(via sciencedaily.com) Original source Researchers found evidence that bilayer graphene quantum dots may host a promising new type of quantum bit based on so-called valley states.
Published Climate change threatens global forest carbon sequestration, study finds
(via sciencedaily.com) Original source Climate change is causing Western U.S. forests to be less effective carbon sinks, even as it boosts the productivity of forests in the Eastern U.S., according to new research.
Published Pacific kelp forests are far older that we thought
(via sciencedaily.com) Original source Fossils of kelp along the Pacific Coast are rare. Until now, the oldest fossil dated from 14 million years ago, leading to the view that today's denizens of the kelp forest -- marine mammals, urchins, sea birds -- coevolved with kelp. A recent amateur discovery pushes back the origin of kelp to 32 million years ago, long before these creatures appeared. A new analysis suggests the first kelp grazers were extinct, hippo-like animals called desmostylians.
Published Innovative graphene-based implantable technology paves the way for high-precision therapeutic applications
(via sciencedaily.com) Original source A new study presents an innovative graphene-based neurotechnology with the potential for a transformative impact in neuroscience and medical applications.
Published Human activity facilitates invasive plants' colonization in Mediterranean ecosystems
(via sciencedaily.com) Original source Some invasive plants can form persistent banks of seeds that remain under the soil for years, and this makes their eradication practically impossible. Over time, this invisible population of large quantities of living, buried plants -- in seed form -- will reoccupy ecosystems and displace the typical flora of the natural environment.
