Published Demon hunting: Physicists confirm 67-year-old prediction of massless, neutral composite particle


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.
Published Unveiling Japan's ancient practice of cranial modification: The case of the Hirota people in Tanegashima



Cranial modification is a form of body alteration where the head is pressed or bound to permanently deform the skull. The practice has been reported across various cultures throughout history. Researchers report that the Hirota people -- who lived on the southern Japanese island of Tanegashima between the 3rd to 7th century CE -- also conducted cranial modification, with indication that both males and females performed the practice.
Published Sea sequin 'bling' links Indonesian islands' ancient communities



Microscopic analysis has revealed that trends in body ornamentation were shared across Indonesian islands.
Published Researchers design efficient iridium catalyst for hydrogen generation


Proton exchange membrane water electrolyzers converts surplus electric energy into transportable hydrogen energy as a clean energy solution. However, slow oxygen evolution reaction rates and high loading levels of expensive metal oxide catalysts limit its practical feasibility. Now, researchers have developed a new tantalum oxide-supported iridium catalyst that significantly boosts the oxygen evolution reaction speed. Additionally, it shows high catalytic activity and long-term stability in prolonged single cell operation.
Published Microbial corrosion of iron


Iron is well-known for rusting, but this doesn't just happen on contact with oxygen and water. Some bacteria are also able to able to decompose iron anaerobically in a process referred to as electrobiocorrosion. The sediment-dwelling bacterium Geobacter sulfurreducens uses electrically conductive protein threads for this purpose. They produce magnetite from the iron, which promotes further corrosion in a positive feedback loop.
Published China's oldest water pipes were a communal effort



A system of ancient ceramic water pipes, the oldest ever unearthed in China, shows that neolithic people were capable of complex engineering feats without the need for a centralized state authority, finds a new study.
Published Zentropy and the art of creating new ferroelectric materials


Systems in the Universe trend toward disorder, with only applied energy keeping the chaos at bay. The concept is called entropy, and examples can be found everywhere: ice melting, campfire burning, water boiling. Zentropy theory, however, adds another level to the mix.
Published Chloride ions from seawater eyed as possible lithium replacement in batteries of the future


Sodium, Potassium and zinc have all been promising contenders for lithium's place in rechargeable batteries of the future, but researchers have added an unusual and more abundant competitor to the mix: chloride, the richest negatively charged ions in seawater. Xiaowei Teng, the James H. Manning professor of Chemical Engineering at WPI, has discovered a new redox chemistry empowered by chloride ions for the development of seawater green batteries.
Published Fossil feces infested with parasites from over 200 million years ago



Fossilized feces preserve evidence of ancient parasites that infected an aquatic predator over 200 million years ago, according to a new study.
Published Quantum material exhibits 'non-local' behavior that mimics brain function


New research shows that electrical stimuli passed between neighboring electrodes can also affect non-neighboring electrodes. Known as non-locality, this discovery is a crucial milestone toward creating brain-like computers with minimal energy requirements.
Published Roman road network spanning the South West identified in new research



New research has found evidence that a Roman road network spanned Devon and Cornwall and connected significant settlements with military forts across the two counties as well as wider Britannia.
Published Single drop of ethanol to revolutionize nanosensor manufacture


Engineers have developed a breakthrough technique to make the processing of nanosensors cheaper, greener and more effective by using a single drop of ethanol to replace heat processing of nanoparticle networks, allowing a wider range of materials to be used to make these sensors.
Published Mussel-inspired membrane can boost sustainability and add value to industrial wastewater treatment


Engineers have developed a new kind of membrane that separates chemicals within wastewater so effectively that they can be reused, presenting a new opportunity for industries to improve sustainability, while extracting valuable by-products and chemicals from wastewater.
Published Faster thin film devices for energy storage and electronics


An international research team reported the first realization of single-crystalline T-Nb2O5 thin films having two-dimensional (2D) vertical ionic transport channels, which results in a fast and colossal insulator-metal transition via Li ion intercalation through the 2D channels.
Published Using gemstones' unique characteristics to uncover ancient trade routes



Gems' unique elemental composition and atomic orientation act as a fingerprint, enabling researchers to uncover the stones' past, and with it, historical trade routes. Scientists now employ three modern spectroscopic techniques to rapidly analyze gems found in the Arabian-Nubian Shield and compare them with similar gems from around the world. They have identified elements that influence gems' color, differentiated stones found within and outside the region, and distinguished natural from synthetic.
Published Cracking in lithium-ion batteries speeds up electric vehicle charging


Rather than being solely detrimental, cracks in the positive electrode of lithium-ion batteries reduce battery charge time, research shows. This runs counter to the view of many electric vehicle manufacturers, who try to minimize cracking because it decreases battery longevity.
Published Energy-storing supercapacitor from cement, water, black carbon


Engineers have created a 'supercapacitor' made of ancient, abundant materials, that can store large amounts of energy. Made of just cement, water, and carbon black (which resembles powdered charcoal), the device could form the basis for inexpensive systems that store intermittently renewable energy, such as solar or wind energy.
Published Scientists create novel approach to control energy waves in 4D


Everyday life involves the three dimensions or 3D -- along an X, Y and Z axis, or up and down, left and right, and forward and back. But, in recent years scientists have explored a 'fourth dimension' (4D), or synthetic dimension, as an extension of our current physical reality.
Published 'Time-traveling' pathogens in melting permafrost pose likely risk to environment



Ancient pathogens that escape from melting permafrost have real potential to damage microbial communities and might potentially threaten human health, according to a new study.
Published New insights into the origin of the Indo-European languages



An international team of linguists and geneticists has achieved a significant breakthrough in our understanding of the origins of Indo-European, a family of languages spoken by nearly half of the world's population.
