Published A new theoretical development clarifies water's electronic structure
(via sciencedaily.com) Original source Scientists have decoded the electronic structure of water, opening up new perspectives for technological and environmental applications.
Published Plant seed and fruit analysis from the biblical home of Goliath sheds unprecedented light on Philistine ritual practices
(via sciencedaily.com) Original source While many aspects of Philistine culture are well-documented, the specifics of Philistine religious practices and deities have long remained shrouded in mystery. A recent study contributes valuable new data to our understanding of the Philistine's ritual practices. The discovery of numerous plants in two temples unearthed at the site unraveled unprecedented insights into Philistine cultic rituals and beliefs -- their temple food ingredients, timing of ceremonies, and plants for temple decoration.
Published Scientists closer to solving mysteries of universe after measuring gravity in quantum world
(via sciencedaily.com) Original source Scientists are closer to unravelling the mysterious forces of the universe after working out how to measure gravity on a microscopic level. Experts have never fully understood how the force works in the tiny quantum world -- but now physicists have successfully detected a weak gravitational pull on a tiny particle using a new technique.
Published Measuring the properties of light: Scientists realize new method for determining quantum states
(via sciencedaily.com) Original source Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect individual light particles -- for so-called homodyne detection. The ability to characterize optical quantum states makes the method an essential tool for quantum information processing.
Published Biggest Holocene volcano eruption found by seabed survey
(via sciencedaily.com) Original source A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.
Published Physicists discover a quantum state with a new type of emergent particles: Six-flux composite fermions
(via sciencedaily.com) Original source Physicists have reported a new fractional quantum Hall state that is very different from all other known fractional states and will invoke the existence of a new type of emergent particle, which they are calling six-flux composite fermions.
Published Revolutionary breakthrough in solar energy: Most efficient QD solar cells
(via sciencedaily.com) Original source A research team has unveiled a novel ligand exchange technique that enables the synthesis of organic cation-based perovskite quantum dots (PQDs), ensuring exceptional stability while suppressing internal defects in the photoactive layer of solar cells.
Published Electrons become fractions of themselves in graphene
(via sciencedaily.com) Original source Physicists have observed fractional quantum Hall effect in simple pentalayer graphene. The finding could make it easier to develop more robust quantum computers.
Published Did neanderthals use glue? Researchers find evidence that sticks
(via sciencedaily.com) Original source Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher level of cognition and cultural development than previously thought.
Published Engineers achieve breakthrough in quantum sensing
(via sciencedaily.com) Original source A collaborative project has made a breakthrough in enhancing the speed and resolution of wide-field quantum sensing, leading to new opportunities in scientific research and practical applications.
Published Ancient DNA reveals Down syndrome in past human societies
(via sciencedaily.com) Original source By analysing ancient DNA, an international team of researchers have uncovered cases of chromosomal disorders, including what could be the first case of Edwards syndrome ever identified from prehistoric remains.
Published A star like a Matryoshka doll: New theory for gravastars
(via sciencedaily.com) Original source If gravitational condensate stars (or gravastars) actually existed, they would look similar to black holes to a distant observer. Two theoretical physicists have now found a new solution to Albert Einstein's theory of general relativity, according to which gravitational stars could be structured like a Russian matryoshka doll, with one gravastar located inside another.
Published A lighthouse in the Gobi desert
(via sciencedaily.com) Original source A new study explores the weight great fossil sites have on our understanding of evolutionary relationships between fossil groups and quantified the power these sites have on our understanding of evolutionary history. Surprisingly, the authors discovered that the wind-swept sand deposits of the Late Cretaceous Gobi Desert's extraordinarily diverse and well-preserved fossil lizard record shapes our understanding of their evolutionary history more than any other site on the planet.
Published Anthropologists' research unveils early stone plaza in the Andes
(via sciencedaily.com) Original source Located at the Callacpuma archaeological site in the Cajamarca Basin of northern Peru, the plaza is built with large, vertically placed megalithic stones -- a construction method previously unseen in the Andes.
Published Vittrup Man crossed over from forager to farmer before being sacrificed in Denmark
(via sciencedaily.com) Original source Vittrup Man was born along the Scandinavian coast before moving to Denmark, where he was later sacrificed, according to a new study.
Published Some Pre-Roman humans were buried with dogs, horses and other animals
(via sciencedaily.com) Original source Some people from an ancient community in what is now northern Italy were interred with animals and animal parts from species such as dogs, horses and pigs. The reasons remain mysterious, but might indicate an enduring companion relationship between these humans and animals, or religious sacrificial practices, according to a new study.
Published Did Eurasia's dominant East-West axis 'turn the fortunes of history'?
(via sciencedaily.com) Original source Jared Diamond proposed that Eurasia's unique geographic axis of orientation fueled a rapid spread of critical innovations among its societies, leading to a cultural and military dominance over other regions. A team of ecologists and cultural evolutionists from the USA, Germany and New Zealand harnessed extensive cultural, environmental and linguistic databases to test these claims. They found that environmental barriers have influenced cultural spread but do not consistently favour Eurasia.
Published Fundamental equation for superconducting quantum bits revised
(via sciencedaily.com) Original source Physicists have uncovered that Josephson tunnel junctions -- the fundamental building blocks of superconducting quantum computers -- are more complex than previously thought. Just like overtones in a musical instrument, harmonics are superimposed on the fundamental mode. As a consequence, corrections may lead to quantum bits that are 2 to 7 times more stable. The researchers support their findings with experimental evidence from multiple laboratories across the globe.
Published A 'quantum leap' at room temperature
(via sciencedaily.com) Original source Scientists have achieved a milestone by controlling quantum phenomena at room temperature.
Published Great apes playfully tease each other
(via sciencedaily.com) Original source Babies playfully tease others as young as eight months of age. Since language is not required for this behavior, similar kinds of playful teasing might be present in non-human animals. Now cognitive biologists and primatologists have documented playful teasing in four species of great apes. Like joking behavior in humans, ape teasing is provocative, persistent, and includes elements of surprise and play. Because all four great ape species used playful teasing, it is likely that the prerequisites for humor evolved in the human lineage at least 13 million years ago.
