Glucagon receptor structures uncover new arrestin interaction mechanism
G protein-coupled receptors (GPCRs) are essential for cell signal transduction and constitute the largest drug target protein family. Upon agonist stimulation, these receptors activate multiple downstream transducers, including G proteins and arresti.....»»
A strategy to realize the efficient resonant absorption of guided water waves
The absorption of water waves is the process through which water waves lose their energy, thus reducing their impact on shores or other solid structures surrounding them. Enabling this absorption process in real-world settings could help protect coas.....»»
New technology to assemble three-dimensional structures using gold nanoparticles confined in nanocapsules
A research group led by Assoc. Prof. Shota Kuwahara of Toho University and Assoc. Prof. Masato Kuwahara of Nagoya University has developed a new technology that enables the creation of three-dimensional structures of gold nanoparticles confined withi.....»»
Zoo-housed carnivores react positively to novel improvements to their enclosures, study suggests
Nottingham Trent University research revealed how carnivores became significantly more active and engaged more with their enclosures when given additional enrichment such as different types of feeding, new structures, the introduction of manipulable.....»»
A new microfabrication strategy for multifunctional 3D artificial sharkskin
Sharks in nature swim at high speeds in a deep ocean due to their high drag reduction ability. Water flows around the sharkskin become disrupted by staggered and overlapping microscale structures named denticles. In addition to this surface roughness.....»»
A mechanism of pressure-induced glass phase transition leading to advanced phase-change memories
When temperature or pressure is applied to a material, its state changes from liquid to solid or remains solid but exhibits structural changes. This change is called a phase transition or change......»»
Researchers discover a mechanism that controls the identity of stem cells
Researchers at the University of California, Irvine, discovered a mechanism that controls the identity of stem cells. When this mechanism fails, embryonic stem cells revert back in time and become totipotent......»»
Team reviews phosphine ligand-induced structural transformation of metal nanoclusters
A team of researchers has reviewed a unique method for reforming the structures of ultra-small nanomaterials. These nanomaterials, called metal nanoclusters, bridge the gap between the metal atom and the bulk metal, making them highly useful in both.....»»
How to solve Sarentu Totems in Avatar: Frontiers of Pandora
Sarentu Totems are ancient, mysterious structures that need to be viewed from a specific angle in Avatar: Frontiers of Pandora. Here's how to find that spot......»»
Bowtie resonators that build themselves bridge the gap between nanoscopic and macroscopic
A central goal in quantum optics and photonics is to increase the strength of the interaction between light and matter to produce, for example, better photodetectors or quantum light sources. The best way to do that is to use optical resonators that.....»»
Aging societies more vulnerable to collapse, suggests analysis
Societies and political structures, like the humans they serve, appear to become more fragile as they age, according to an analysis of hundreds of pre-modern societies. A new study, which holds implications for the modern world, provides the first qu.....»»
An anomalous relativistic emission arising from the intense interaction of lasers with plasma mirrors
Interactions between intense laser pulses and plasma mirrors have been the focus of several recent physics studies due to the interesting effects they produce. Experiments have revealed that these interactions can generate a non-linear physical proce.....»»
A sun protection mechanism helps plants to survive
Just as people can get sunburned, plants can also suffer from too much sunlight. To stay healthy, they use an internal "sun protection mechanism." Pierrick Bru, a Ph.D. student working with Alizée Malnoë at Umeå Plant Science Centre and Umeå Univ.....»»
A theoretical approach to ferroelectricity in hafnia-related materials
Hafnia ferroelectrics are based on their technical promise and remarkable behaviors, where the peculiarities stem from an active extrinsic mechanism that contributes to their properties from a growing number of new intrinsic features......»»
Creating 3D-printed materials that shrink more precisely
From houses to hearing aids, three-dimensional (3D) printing is revolutionizing how we create complex structures at scale. Zooming down to the micro and nano levels, a process known as two-photon polymerization lithography (TPL) allows scientists and.....»»

Trove of combos is >45 times larger than number unearthed in entire history of science. Enlarge / The researchers identified novel materials by using machine learning to first generate candidate structures and then gauge their li.....»»
Laser-induced hydrothermal growth for electrocatalytic applications
In the new study published in the journal International Journal of Extreme Manufacturing on 1 November 2023, researchers from the UK and China reported a novel technique based on a laser-induced hydrothermal reaction (LIHR) mechanism for the growth o.....»»
Researchers design smaller, more cost-efficient electron cryo-microscope
Researchers have designed a new electron cryo-microscope that is a fraction of the size and cost of current alternatives and used it to determine 11 atomic structures. The breakthrough aims to slash the cost of running electron cryo-microscopy (cryoE.....»»
Research reveals clever dosage control mechanism of biallelic genes
Have you ever wondered why we carry two copies of each chromosome in all of our cells? During reproduction, we receive one from each of our parents. This means that we also receive two copies, or alleles, of each gene—one allele per chromosome or p.....»»
Plants found to recruit distinct chemical activities of coumarins under different soil pHs
Plants have two main uptake mechanisms to obtain iron (Fe) from the soils. The type of strategy employed depends on the botanical classification of the plant. In the so-called strategy-I mechanism, plants must first reduce the trivalent iron (Fe3+) i.....»»
