Published Evolution driving improvements in racehorse speed
(via sciencedaily.com) Original source A new study has found that genetic improvement is underlying the increasing speed of Britain's thoroughbreds. This contrasts with earlier studies that suggested racehorses were showing no genetic improvement in response to selection by breeders.
Published Biological specimens imaged with X-rays without damage
(via sciencedaily.com) Original source Scientists have managed to image delicate biological structures without damaging them. Their new technique generates high resolution X-ray images of dried biological material that has not been frozen, coated, or otherwise altered beforehand -- all with little to no damage to the sample. This method, which is also used for airport baggage scanning, can generate images of the material at nanometer resolution.
Published Nanorobotic system presents new options for targeting fungal infections
(via sciencedaily.com) Researchers have developed a nanorobot system that targets fungal infections in the mouth.
Published Protein-based nano-'computer' evolves in ability to influence cell behavior
(via sciencedaily.com) Original source The first protein-based nano-computing agent that functions as a circuit has been created. The milestone puts them one step closer to developing next-generation cell-based therapies to treat diseases like diabetes and cancer.
Published Hydrogen battery: Storing hydrogen in coal may help power clean energy economy
(via sciencedaily.com) Original source The quest to develop hydrogen as a clean energy source that could curb our dependence on fossil fuels may lead to an unexpected place -- coal. Scientists have found that coal may represent a potential way to store hydrogen gas, much like batteries store energy for future use, addressing a major hurdle in developing a clean energy supply chain.
Published Using AI, scientists find a drug that could combat drug-resistant infections
(via sciencedaily.com) Original source Using AI, researchers identified a new antibiotic that can kill Acinetobacter baumannii, a type of bacteria that is responsible for many drug-resistant infections.
Published Brain imaging is on the move with wearable scanning development
(via sciencedaily.com) Original source New research has demonstrated that a wearable brain scanner can measure brain function whilst people are standing and walking around. This breakthrough could help better understand and diagnose a range of neurological problems that affect movement, including Parkinson's Disease, stroke and concussion.
Published Making the structure of 'fire ice' with nanoparticles
(via sciencedaily.com) Original source Cage structures made with nanoparticles could be a route toward making organized nanostructures with mixed materials, and researchers have shown how to achieve this through computer simulations.
Published Scientists propose revolution in complex systems modelling with quantum technologies
(via sciencedaily.com) Original source Scientists have made a significant advancement with quantum technologies that could transform complex systems modelling with an accurate and effective approach that requires significantly re-duced memory.
Published Propellers are louder over ground
(via sciencedaily.com) Original source The effects of the ground on propeller noise have now been measured experimentally.
Published Medical 'microrobots' could one day treat bladder disease, other human illnesses
(via sciencedaily.com) Original source Engineers have designed a new class of 'microrobots' several times smaller than the width of a human hair that may be able to treat human illnesses like interstitial cystitis -- a painful bladder disease that affects millions of Americans.
Published New method predicts extreme events more accurately
(via sciencedaily.com) Original source A new study has used global storm-resolving simulations and machine learning to create an algorithm that can deal separately with two different scales of cloud organization: those resolved by a climate model, and those that cannot be resolved as they are too small. This new approach addresses the missing piece of information in traditional climate model parameterizations and provides a way to predict precipitation intensity and variability more precisely.
Published New potential drug target for Alzheimer's disease
(via sciencedaily.com) Original source Tau protein is implicated in many neurogenerative diseases, including Alzheimer's. New findings point to a new potential drug target to slow the progress of the disease: the enzymes responsible for sulfation called heparan sulfate 3-O transferases.
Published Quantum matter breakthrough: Tuning density waves
(via sciencedaily.com) Original source Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most complex problems in physics.
Published Flexing crystalline structures provide path to a solid energy future
(via sciencedaily.com) Original source Researchers have uncovered the atomic mechanisms that make a class of compounds called argyrodites attractive candidates for both solid-state battery electrolytes and thermoelectric energy converters. The discoveries -- and the machine learning approach used to make them -- could help usher in a new era of energy storage for applications such as household battery walls and fast-charging electric vehicles.
Published Researchers build bee robot that can twist
(via sciencedaily.com) Original source A robotic bee that can fly fully in all directions has been developed. With four wings made out of carbon fiber and mylar as well as four light-weight actuators to control each wing, the Bee++ prototype is the first to fly stably in all directions. That includes the tricky twisting motion known as yaw, with the Bee++ fully achieving the six degrees of free movement that a typical flying insect displays.
Published CT scan best at predicting heart disease risk in middle age
(via sciencedaily.com) Original source CT scans are better at predicting a middle-aged person's risk for a heart disease, such as a heart attack, than genetics, reports a new study. Conventional measures of risk factor levels include blood pressure and cholesterol. Scientists had hoped genetics could better predict risk than conventional measure, but only when considering CT scan, half the study participants moved into the high-risk group.
Published Fluorine-based new drug synthesis at lightning speed
(via sciencedaily.com) Original source Researchers synthesize fluorine-based compound via rapid biphasic (gas and liquid) mixing.
Published Uncovering universal physics in the dynamics of a quantum system
(via sciencedaily.com) Original source New experiments using one-dimensional gases of ultra-cold atoms reveal a universality in how quantum systems composed of many particles change over time following a large influx of energy that throws the system out of equilibrium.
Published A better way to study ocean currents
(via sciencedaily.com) Original source Computer scientists and oceanographers developed a machine-learning model that generates more accurate predictions about the velocities of ocean currents. The model could help make more precise weather forecasts or effectively predict how oil will spread after a spill.
