Published Materials research revolutionized by a small change
(via sciencedaily.com) Original source Scientists develop the next generation of highly efficient memory materials with atom-level control.
Published Microrobot-packed pill shows promise for treating inflammatory bowel disease in mice
(via sciencedaily.com) Original source Engineers have developed a pill that releases microscopic robots, or microrobots, into the colon to treat inflammatory bowel disease (IBD). The experimental treatment, given orally, has shown success in mice. It significantly reduced IBD symptoms and promoted the healing of damaged colon tissue without causing toxic side effects.
Published A new study highlights potential of ultrafast laser processing for next-gen devices
(via sciencedaily.com) Original source A new study uncovers the remarkable potential of ultrafast lasers that could provide innovative solutions in 2D materials processing for many technology developers such as high-speed photodetectors, flexible electronics, biohybrids, and next-generation solar cells.
Published Revealing the dynamic choreography inside multilayer vesicles
(via sciencedaily.com) Original source Our cells and the machinery inside them are engaged in a constant dance. This dance involves some surprisingly complicated choreography within the lipid bilayers that comprise cell membranes and vesicles -- structures that transport waste or food within cells. In a recent paper, researchers shed some light on how these vesicles self-assemble, knowledge that could help scientists design bio-inspired vesicles for drug-delivery or inspire them to create life-like synthetic materials.
Published Wildfires increasingly threaten oil and gas drill sites, compounding potential health risks
(via sciencedaily.com) Original source More than 100,000 oil and gas wells across the western U.S. are in areas burned by wildfires in recent decades, a new study has found, and some 3 million people live next to wells that in the future could be in the path of fires worsened by climate change.
Published Fuel treatments reduce future wildfire severity
(via sciencedaily.com) Original source There is a common belief that prescribed burning, thinning trees, and clearing underbrush reduce risks of the severity of future fires. But is that true? A new project analyzing 40 studies where wildfire burned into different vegetation treatments, spanning 11 western states. Researchers found overwhelming evidence that in seasonally dry mixed conifer forests in the western U.S., reducing surface and ladder fuels and tree density through thinning, coupled with prescribed burning or pile burning, could reduce future wildfire severity by more than 60% relative to untreated areas.
Published Large wildfires create weather that favors more fire
(via sciencedaily.com) Original source A new study shows soot from large wildfires in California traps sunlight, making days warmer and drier than they ought to be.
Published Researchers film energy materials as they form
(via sciencedaily.com) Original source Shooting a movie in the lab requires special equipment. Especially when the actors are molecules -- invisible to the naked eye -- reacting with each other. 'Imagine trying to film tiny lava flows during a volcanic eruption. Your smartphone camera wouldn't be up to the job.
Published Novel method for measuring nano/microplastic concentrations in soil using spectroscopy
(via sciencedaily.com) Original source Current techniques for measuring nano/microplastic (N/MP) concentrations in soil require the soil organic matter content to be separated and have limited resolution for analyzing N/MPs sized <1 m. Therefore, researchers have developed a novel yet simple method to measure N/MP concentration in different soil types using spectroscopy at two wavelengths. This method does not require the soil to be separated in order to detect the N/MPs and can accurately quantify N/MPs regardless of their size.
Published Golden ball mills as green catalysts
(via sciencedaily.com) Original source A gold-coated milling vessel for ball mills proved to be a real marvel: without any solvents or environmentally harmful chemicals, the team was able to use it to convert alcohols into aldehydes. The catalytic reaction takes place at the gold surface and is mechanically driven. The vessel can be reused multiple times. 'This opens up new prospects for the use of gold in catalysis and shows how traditional materials can contribute to solving modern environmental problems in an innovative way,' says Borchardt.
Published Nano-immunotherapy developed to improve lung cancer treatment
(via sciencedaily.com) Original source Researchers have developed a new nanomedicine therapy that delivers anticancer drugs to lung cancer cells and enhances the immune system's ability to fight cancer. The team showed promising results for the new therapy in cancer cells in the lab and in mouse lung tumor models, with potential applications for improving care and outcomes for patients with tumors that have failed to respond to traditional immunotherapy.
Published Self-assembling and disassembling swarm molecular robots via DNA molecular controller
(via sciencedaily.com) Original source Researchers have succeeded in developing a DNA-based molecular controller. Crucially, this controller enables the autonomous assembly and disassembly of molecular robots, as opposed to manually directing it.
Published Nanosized blocks spontaneously assemble in water to create tiny floating checkerboards
(via sciencedaily.com) Original source Researchers have engineered nanosized cubes that spontaneously form a two-dimensional checkerboard pattern when dropped on the surface of water. The work presents a simple approach to create complex nanostructures through a technique called self-assembly.
Published New way to spot beetle-killed spruce can help forest, wildfire managers
(via sciencedaily.com) Original source A new machine-learning system can automatically produce detailed maps from satellite data to show locations of likely beetle-killed spruce trees in Alaska, even in forests of low and moderate infestation where identification is otherwise difficult. The automated process can help forestry and wildfire managers in their decisions. That's critical as the beetle infestation spreads.
Published Swimming microrobots deliver cancer-fighting drugs to metastatic lung tumors in mice
(via sciencedaily.com) Original source Engineers have developed microscopic robots, known as microrobots, capable of swimming through the lungs to deliver cancer-fighting medication directly to metastatic tumors. This approach has shown promise in mice, where it inhibited the growth and spread of tumors that had metastasized to the lungs, thereby boosting survival rates compared to control treatments.
Published Quantum dots and metasurfaces: Deep connections in the nano world
(via sciencedaily.com) Original source A team has developed printable, highly efficient light-emitting metasurfaces.
Published Uncovering the nature of emergent magnetic monopoles
(via sciencedaily.com) Original source To understand the unique physical phenomena associated with the properties of magnetic hedgehogs and antihedgehogs, which behave as virtual magnetic monopoles and antimonopoles respectively, it is essential to study their intrinsic excitations. In a new study, researchers revealed the dynamical nature of collective excitation modes in hedgehog lattices in itinerant chiral magnets. Their findings serve as the foundation for studying the dynamics of emergent magnetic monopoles in magnets.
Published Splitting hairs: Science of biomechanics to understand of bad hair days
(via sciencedaily.com) Original source Academics are often accused of 'splitting hairs', but a team has now devised a machine to do just that. We all have a bad hair day from time to time, and split ends are a common problem. However, the science behind this kind of hair damage is poorly understood, which is why scientists are investigating this knotty problem.
