Published Scientists develop an energy-efficient wireless power and information transfer system
(via sciencedaily.com) Simultaneous wireless information and power transfer (SWIPT)-aided nonorthogonal multiple access (NOMA) system, used for communication in the Industrial Internet of Things (IIoTs), suffers from significant energy loss with transmission distance. Now, researchers have developed an energy-efficient framework by applying SWIPT-NOMA to a distributed antenna system. This technology is expected to pave the way for more efficient and optimized IoT environments.
Published Better cybersecurity with new material
(via sciencedaily.com) Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption. The researchers behind the study believe that the new technology paves the way for a new type of quantum communication.
Published Mutation rates in whales are much higher than previously reported
(via sciencedaily.com) Original source An international team of marine scientists has studied the DNA of family groups from four different whale species to estimate their mutation rates. Using the newly determined rates, the group found that the number of humpback whales in the North Atlantic before whaling was 86 percent lower than earlier studies suggested.
Published Europe's very own dinosaurs -- the enigmatic Late Cretaceous rhabdodontids
(via sciencedaily.com) Original source A new study brings together intriguing details about the little-known Rhabdodontidae dinosaurs of Late Cretaceous Europe. These gregarious herbivores, characterized by robust builds and beaks specialized for tough vegetation, inhabited the European archipelago. Despite being widespread and abundant, they vanished in Western Europe due to environmental changes around 69 million years ago, while surviving longer in Eastern Europe. Their fossil record offers valuable insights into their evolution and lifestyle, although its limited nature still challenges comprehensive understanding.
Published New 'droplet battery' could pave the way for miniature bio-integrated devices
(via sciencedaily.com) Researchers have developed a miniature battery that could be used to power tiny devices integrated into human tissues. The design uses an ionic gradient across a chain of droplets -- inspired by how electric eels generate electricity. The device was able to regulate the biological activity of human neurons. This could open the way to the development of tiny bio-integrated devices, with a range of applications in biology and medicine.
Published Three-eyed distant relative of insects and crustaceans reveals amazing detail of early animal evolution
(via sciencedaily.com) Original source Scientists use cutting edge scanning technology to reconstruct 'fossil monster' that lived half a billion years ago. The creature's soft anatomy was well-preserved, allowing it to be imaged almost completely: It fills a gap in our understanding of the evolution of arthropods such as insects and crustaceans.
Published Direct power generation from methylcyclohexane using solid oxide fuel cells
(via sciencedaily.com) Original source Methylcyclohexane is very promising as a hydrogen carrier that can safely and efficiently transport and store hydrogen. However, the dehydrogenation process using catalysts has issues due to its durability and large energy loss. Recently, researchers have succeeded in using solid oxide fuel cells to generate electricity directly from methylcyclohexane and recover toluene for reuse. This research is expected to not only reduce energy requirements but also explore new chemical synthesis by fuel cells.
Published Wastewater pipe dig reveals 'fossil treasure trove'
(via sciencedaily.com) Original source A new article describes the 266 fossil species as one of the richest and most diverse groups of three-million-year-old fauna ever found in New Zealand. At least ten previously unknown species will be described and named in future research. Fossils of the world's oldest known flax snails, an extinct sawshark spine, and great white shark teeth have all been found in a mound of sand excavated from beneath Mangere Wastewater Treatment Plant in 2020.
Published Researcher finds inspiration from spider webs and beetles to harvest fresh water from thin air
(via sciencedaily.com) A team of researchers is designing novel systems to capture water vapor in the air and turn it into liquid. They have developed sponges or membranes with a large surface area that continually capture moisture from their surrounding environment.
Published Math enables blending hydrogen in natural gas pipelines
(via sciencedaily.com) Mathematical modeling can show how to safely blend hydrogen with natural gas for transport in existing pipeline systems. A secure and reliable transition to hydrogen is one of the proposed solutions for the shift to a net-zero-carbon economy.
Published Scientists invent micrometers-thin battery charged by saline solution that could power smart contact lenses
(via sciencedaily.com) Scientists have developed a flexible battery as thin as a human cornea, which stores electricity when it is immersed in saline solution, and which could one day power smart contact lenses.
Published New study finds ways to suppress lithium plating in automotive batteries for faster charging electric vehicles
(via sciencedaily.com) A new study has found a way to prevent lithium plating in electric vehicle batteries, which could lead to faster charging times.
Published Newly discovered 'primitive cousins of T rex' shed light on the end of the age of dinosaurs in Africa
(via sciencedaily.com) Original source Researchers have discovered the fossils of two new abelisaurs in Morocco, showing the diversity of dinosaurs in this region at the end of the Cretaceous period.
Published Steam condenser coating could save 460M tons of CO2 annually
(via sciencedaily.com) If coal and natural gas power generation were 2% more efficient, then, every year, there could be 460 million fewer tons of carbon dioxide released and 2 trillion fewer gallons of water used. A recent innovation to the steam cycle used in fossil fuel power generation could achieve this.
Published 'Topological gardening' to achieve unexpected spin transport
(via sciencedaily.com) 'Trimming' the edge-states of a topological insulator yields a new class of material featuring unconventional 'two way' edge transport in a new theoretical study. The new material, a topological crystalline insulator (TCI) forms a promising addition to the family of topological materials and significantly broadens the scope of materials with topologically nontrivial properties, paving the way for novel techniques to manipulate edge transport in future electronics. For example, 'switching' the TCI via an electric field breaking the symmetry supporting the nontrivial band topology, thus suppressing the edge current.

Published Demon hunting: Physicists confirm 67-year-old prediction of massless, neutral composite particle
(via sciencedaily.com) In 1956, theoretical physicist David Pines predicted that electrons in a solid can do something strange. While they normally have a mass and an electric charge, Pines asserted that they can combine to form a composite particle that is massless, neutral, and does not interact with light. He called this particle a 'demon.' Now, researchers have finally found Pines' demon 67 years after it was predicted.
