Scientists at the University of Leicester discovered that jewel wasps can slow down their biological rate of ageing by undergoing a natural 'time-out' as larvae. This pause in development extends lifespan and decelerates the epigenetic clock, tracking chemical changes in DNA.
Researchers visualized the dynamic shuttling of α-CD rings along a PEG chain in real time, revealing localized structural changes. The study introduces a new method for analyzing supramolecular polymers and could pave the way for energy-efficient molecular motors.
Research team develops a new design strategy to enhance efficiency, stability, and stretchability of polymer solar cells. The discovery uses a three-dimensional aromatic-core tethered tetrameric acceptor, achieving significant improvements in performance and durability.
A commonly used mathematical approach to describe fluorescence evolution in solids cannot be applied to liquids, where molecules are free to move. This can lead to erroneous interpretations of experimental data and wrong conclusions.
Researchers will examine cognitive and psychomotor functions to compare effects of CBD on driving performance between men and women. The five-year study aims to provide a comprehensive understanding of the substance's influence.
A mouse study found that heart failure with preserved ejection fraction (HFpEF) differs between male and female mice, with females exhibiting altered heart filament proteins and males showing slowed calcium removal. This may lead to different treatment strategies for women compared to men with HFpEF.
Researchers found that Angelica gigas extract improves vascular function in high-fat diet rats, reversing endothelial dysfunction and increasing NO bioavailability. The extract regulates IRE1α sulfonation and RIDD signaling, promoting NO production via the SIRT1-eNOS axis.
The study reveals that NO forms a new compound, NO-ferroheme, which significantly expands blood vessels and directly activates guanylyl cyclase. This finding challenges the long-held hypothesis on nitric oxide signalling in blood vessels.
A recent study published in Applied Physics Letters reveals the dynamics of water molecules in tetra-n-butylammonium bromide semiclathrate hydrate using quasi-elastic neutron scattering. The research found that water molecules rapidly reorient, and their motion is consistent with breaking hydrogen bonds.
Researchers have discovered a novel copper protein binding site that shows promise for use in magnetic resonance imaging (MRI) contrast agents, potentially leading to clearer images and improved diagnoses. The new structure displayed highly effective levels of relaxivity, equal and superior to existing Gd(III) agents used in clinical MRI.
Researchers developed a polarization-angle-resolved Raman microscope to visualize disorder effects on ferroelectric polarization. The study reveals slow response of nanometer-scale electric polarization, enabling significant charge storage and enhanced dielectric properties.
Scientists at the University of Tokyo have discovered a pheromone that reduces fear in rats, which could lead to more humane methods of pest control. The researchers found that this pheromone, 2-methylbutyric acid, can calm both lab and wild rats, reducing their fear responses.
Researchers at The University of Tokyo introduced a new physical model that predicts the dynamics of glassy materials based solely on their local degree of atomic structural order. This theory greatly improves our understanding of how glassy liquids become more viscous on cooling, with potential applications in manufacturing.
A randomized controlled trial found that both structural and relaxation massage types helped alleviate chronic low back pain and improve function. Massage patients experienced significant reductions in pain, improved functioning, and increased activity compared to those with usual care.
Researchers have identified key features of cardiac troponin C, a protein that regulates muscle contraction. The study's findings may lead to the development of new therapies for patients with congestive heart failure, by targeting calcium binding to regulatory proteins.
