Published Offshore wind farms are vulnerable to cyberattacks



Researchers have presented a new study on cyberattack risks to offshore wind farms in Glasgow, United Kingdom. They looked specifically at wind farms that use voltage-source-converter high-voltage direct-current (VSC-HVDC) connections, which are rapidly becoming the most cost-effective solution to harvest offshore wind energy around the world. They found that their complex, hybrid-communication architecture presents multiple access points for cyberattacks.
Published Fast-charging lithium battery seeks to eliminate 'range anxiety'



Engineers have created a new lithium battery that can charge in under five minutes -- faster than any such battery on the market -- while maintaining stable performance over extended cycles of charging and discharging.
Published Research of water droplet interfaces that offer the secret ingredient for building life



Scientists have experimental evidence that the key step in protein formation can occur in droplets of pure water.
Published New model predicts how shoe properties affect a runner's performance



A new model predicts how shoe properties will affect a runner's performance. The model could be a tool for designers looking to push the boundaries of sneaker design.
Published New study unveils how plants control the production of reactive oxygen species



Reactive oxygen species (ROS), though generally regarded as toxic byproducts of biological processes, serve many important functions in plants. However, the precise mechanism that plants use to regulate the production of ROS remains elusive. In a recent study, researchers clarified how an important ROS-generating enzyme is activated, revealing mechanisms likely conserved across all land plants. Their findings could pave the way for breakthroughs in agricultural and environmental remediation tools.
Published A new 3D bioprinted model offers a novel tool to study common liver disease, and perhaps find an effective treatment



Metabolic dysfunction--associated steatohepatitis or MASH (formerly known as nonalcoholic steatohepatitis) is an inflammatory, liver-scarring disease that affects 1.5% to 6.5% of all U.S. adults. There are no approved pharmacological therapies for MASH and in the most severe case, the only recourse is liver transplantation.
Published When lab-trained AI meets the real world, 'mistakes can happen'



Human pathologists are extensively trained to detect when tissue samples from one patient mistakenly end up on another patient's microscope slides (a problem known as tissue contamination). But such contamination can easily confuse artificial intelligence (AI) models, which are often trained in pristine, simulated environments, reports a new study. Each of the four AI models in the study paid too much attention to the tissue contamination, which resulted in errors when diagnosing or detecting vessel damage, gestational age, lesions and prostate cancer, the study found.
Published New video camera system captures the colored world that animals see, in motion



A new camera system allows ecologists and filmmakers to produce videos that accurately replicate the colors that different animals see in natural settings.
Published Water, water everywhere and now we may have drops to drink



Researchers have achieved a major breakthrough in Redox Flow Desalination (RFD), an emerging electrochemical technique that can turn seawater into potable drinking water and also store affordable renewable energy.
Published Discovering the physics behind 300-year-old firefighting methods



Inspired by a 1725 fire engine that pumped water at larger distances and higher speeds than previously possible, authors analyzed the pressure chamber's Windkessel effect to capture the physics behind this widely used, enduring technology. They compared the initial state of the chamber, the rate at which bucket brigades could pour water in (volumetric inflow), the length of time pressure builds, and the effects on output flow rate. Next, the authors plan to examine the physiological Windkessel involved in the heart-aorta system.
Published Uncovering the secrets behind the silent flight of owls



Owls produce negligible noise while flying. While many studies have linked the micro-fringes in owl wings to their silent flight, the exact mechanisms have been unclear. Now, a team of researchers has uncovered the effects of these micro-fringes on the sound and aerodynamic performance of owl wings through computational fluid dynamic simulations. Their findings can inspire biomimetic designs for the development of low-noise fluid machinery.

A newly published study provides guidance for building accurate mathematical models for gene regulatory networks.
Published Potential use of topological magnets for magneto-thermoelectric energy conversion



Scientists are eager to harness the unique electrical properties of topological magnets for advancing thermoelectric materials. A collaborative research group has successfully induced positive and negative polarities, unlocking the potential for generating thermoelectric energy from materials with topological magnet properties.
Published Deepwater Horizon oil spill study could lead to overhaul of cleanup processes worldwide



New research could lead to major improvements in marine oil spill cleanup processes. The innovative study assessed the impact of the Deepwater Horizon oil spill on microscopic seawater bacteria that perform a significant role in ecosystem functioning.
Published Endless biotechnological innovation requires a creative approach



Scientists working on biological design should focus on the idiosyncrasies of biological systems over optimization, according to new research.
Published DNA origami folded into tiny motor



Scientists have created a working nanoscale electomotor. The science team designed a turbine engineered from DNA that is powered by hydrodynamic flow inside a nanopore, a nanometer-sized hole in a membrane of solid-state silicon nitride. The tiny motor could help spark research into future applications such as building molecular factories or even medical probes of molecules inside the bloodstream.
Published Clutch-stack-driven molecular gears in crystals could propel material innovation



Temperature-controlled, reversible shifting of molecular gear motion in a solid crystal opens new possibilities for material design.
Published Using magnetized neurons to treat Parkinson's disease symptoms



Electrical deep brain stimulation (DBS) is a well-established method for treating disordered movement in Parkinson's disease. However, implanting electrodes in a person's brain is an invasive and imprecise way to stimulate nerve cells. Researchers report a new application for the technique, called magnetogenetics, that uses very small magnets to wirelessly trigger specific, gene-edited nerve cells in the brain. The treatment effectively relieved motor symptoms in mice without damaging surrounding brain tissue.
Published DNA becomes our 'hands' to construct advanced nanoparticle materials



A new paper describes a significant leap forward in assembling polyhedral nanoparticles. The researchers introduce and demonstrate the power of a novel synthetic strategy that expands possibilities in metamaterial design. These are the unusual materials that underpin 'invisibility cloaks' and ultrahigh-speed optical computing systems.
Published Physical processes can have hidden neural network-like abilities



A new study shows that the physics principle of 'nucleation' can perform complex calculations that rival a simple neural network. The work may suggest avenues for new ways to think about computation using the principles of physics.
