Protein from mosquitoes could help control dengue virus infection
NUS scientists have revealed the structure and function of a pupal cuticle protein found in the exoskeleton—a hard covering that supports and protects the bodies of some types of invertebrate animals, especially arthropods—of Aedes aegypti mosqui.....»»
Hubble observes an askew galaxy coaxing star formation from its partner
Arp 300 consists of two interacting galaxies, UGC 05028 (the smaller face-on spiral galaxy) and UGC 05029 (the larger face-on spiral). Likely due to its gravitational dance with its larger partner, UGC 05028 has an asymmetric, irregular structure, wh.....»»
Scientists spin naturalistic silk from artificial spider gland
Researchers have succeeded in creating a device that spins artificial spider silk that closely matches what spiders naturally produce. The artificial silk gland was able to re-create the complex molecular structure of silk by mimicking the various ch.....»»
Scientists solve long-standing block copolymer research conundrum through polymer chain end modifications
Plumber's nightmare structure presents itself as an assemblage where all exits seem to converge inward—a plumber's nightmare but an anticipated uniqueness for researchers, suggesting distinctive traits divergent from traditional materials. Nonethel.....»»
New study reveals impact of skin microorganisms on earthworm toxicity in polluted environments
In a study published in the journal Eco-Environment & Health, researchers from Zhejiang University revealed the crucial role of epidermal microorganisms in influencing earthworm toxicity under environmental stress, notably in conditions of nano zero-.....»»
New study tracks a mammoth’s travels across Alaska
Isotopes trapped in a tusk can be matched to those in the Alaskan landscape. Enlarge (credit: Aunt_Spray / GETTY IMAGES) A single tusk is all that remains of a mammoth that lived approximately 14,000 years ago. Yet that.....»»
Quantum physicists develop robust and ultra-sensitive topological quantum device
A significant breakthrough has been achieved by quantum physicists from Dresden and Würzburg. They've created a semiconductor device where exceptional robustness and sensitivity are ensured by a quantum phenomenon. This topological skin effect shiel.....»»
Early evolution of cicadas revealed by analyses of new fossils
To clarify the early evolutionary history of Cicadoidea fossils, the phylogenetic relationships between Mesozoic fossils and extant Cicadoidea, the macroevolution of body structure adaptations, and their relationship with environmental changes, Dr. J.....»»
Researchers unravel complex 3D structure of thick filaments in human heart
It's been estimated that over one lifetime, a heart will beat 2.5 to 3 billion times without stopping. Yet the mechanics of how the heart physically carries out this function flawlessly, without fail, minute after minute, remains poorly understood on.....»»
New technique visualizes mechanical structure of the cell nucleus for the first time
The cell nucleus is considered to be the control center of vital cellular processes, but its material properties continue to puzzle scientists. An international research team led by MedUni Vienna has now developed a new technique that provides a prev.....»»
Wooly mammoth movements tied to earliest Alaska hunting camps
Researchers have linked the travels of a 14,000-year-old wooly mammoth with the oldest known human settlements in Alaska, providing clues about the relationship between the iconic species and some of the earliest people to travel across the Bering La.....»»
Translating nuclear waste site data into microbial ecosystem insights
A flagship seven-year study led by the University of Oklahoma that explores how environmental stresses influence different ecological processes shaping the composition and structure of microbial communities in groundwater, has been published in the j.....»»
Enhanced photoelectrochemical water splitting with a donor-acceptor polyimide
Polyimide (PI) has emerged as a promising organic photocatalyst owing to its distinct advantages of high visible-light response, facile synthesis, molecularly tunable donor-acceptor structure, and excellent physicochemical stability. However, the syn.....»»
