Published Ground beneath Thwaites Glacier mapped
(via sciencedaily.com) Original source The ground beneath Antarctica's most vulnerable glacier has now been mapped, helping scientists to better understand how it is being affected by climate change. Analysis of the geology below the Thwaites Glacier in West Antarctica shows there is less sedimentary rock than expected -- a finding that could affect how the ice slides and melts in the coming decades.
Published Shedding light on the complex flow dynamics within the small intestine
(via sciencedaily.com) Original source A novel microfluidic device revealing diverse and dynamic flows in the small intestine has now been developed. An innovative experimental platform uses microscopic fluorescent beads as substitutes for gut bacteria in dissected small intestine sections, allowing one to visualize and quantitatively analyze the luminal dynamic flow in the tissues deformed by a pneumatic actuator.
Published Flexible nanoelectrodes can provide fine-grained brain stimulation
(via sciencedaily.com) Original source Engineers have developed ultraflexible implantable nanoelectrodes that can administer long-term, fine-grained brain stimulation.
Published Mitigating climate change through restoration of coastal ecosystems
(via sciencedaily.com) Original source Researchers are proposing a novel pathway through which coastal ecosystem restoration can permanently capture carbon dioxide from the atmosphere. Seagrass and mangroves -- known as blue carbon ecosystems -- naturally capture carbon through photosynthesis, which converts carbon dioxide into living tissue.
Published Self-driving cars lack social intelligence in traffic
(via sciencedaily.com) Original source Self-driving cars fall short when it comes to understanding the social codes in traffic that let human drivers decide whether to give way or drive on, according to new research.
Published Source-shifting metastructures composed of only one resin for location camouflaging
(via sciencedaily.com) Original source Acoustic source-shifters make observers mis-perceive the location of sound by reproducing a sound emanating from a location different from the actual location of a sound source. Researchers have now developed a design approach to produce high-performance source-shifters using a common polymer for location camouflage. Utilizing inverse design based on topology optimization, this development could pave the way for advanced augmented reality and holography technology.
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 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 Deep sea surveys detect over five thousand new species in future mining hotspot
(via sciencedaily.com) Original source There is a massive, mineral-rich region in the Pacific Ocean -- about twice the size of India -- called the Clarion-Clipperton Zone (CCZ), which has already been divided up and assigned to companies for future deep-sea mining. To better understand what may be at risk once companies start mining, a team of biologists has built the first 'CCZ checklist' by compiling all the species records from previous research expeditions to the region. Their estimates of the species diversity of the CCZ included a total of 5,578 different species, an estimated 88% - 92% of which are entirely new to science.
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 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 Consistent link between the seaside and better health
(via sciencedaily.com) Original source Seaside residents and holidaymakers have felt it for centuries, but scientists have only recently started to investigate possible health benefits of the coast. Using data from 15 countries, new research confirms public intuition: Living near, but especially visiting, the seaside is associated with better health regardless of country or personal income.
Published Not so biodegradable: Bio-based plastic and plastic-blend textiles do not biodegrade in the ocean
(via sciencedaily.com) Original source A new study tracked the ability of natural, synthetic, and blended fabrics to biodegrade directly in the ocean.
