Published Researchers advance pigment chemistry with moon-inspired reddish magentas
(via sciencedaily.com) Original source A researcher who made color history in 2009 with a vivid blue pigment has developed durable, reddish magentas inspired by lunar mineralogy and ancient Egyptian chemistry.
Published How tardigrades can survive intense radiation
(via sciencedaily.com) Original source Researchers have discovered that tardigrades -- microscopic animals famed for surviving harsh extremes -- have an unusual response to radiation.
Published Unlocking the 'chain of worms'
(via sciencedaily.com) Original source An international team of scientists has published a single-cell atlas for Pristina leidyi (Pristina), the water nymph worm, a segmented annelid with extraordinary regenerative abilities that has fascinated biologists for more than a century.
Published Switch to green wastewater infrastructure could reduce emissions and provide huge savings according to new research
(via sciencedaily.com) Original source Researchers have shown that a transition to green wastewater-treatment approaches in the U.S. that leverages the potential of carbon-financing could save a staggering $15.6 billion and just under 30 million tons of CO2-equivalent emissions over 40 years.
Published Researchers study effects of solvation and ion valency on metallopolymers
(via sciencedaily.com) Original source Researchers analyzed the effects of solvation and ion valency on metallopolymers, with implications for critical materials recovery and recycling, and environmental remediation.
Published Cell's 'garbage disposal' may have another role: Helping neurons near skin sense the environment
(via sciencedaily.com) Original source The typical job of the proteasome, the garbage disposal of the cell, is to grind down proteins into smaller bits and recycle some of those bits and parts. That's still the case, for the most part, but researchers, studying nerve cells grown in the lab and mice, say that the proteasome's role may go well beyond that.
Published How seaweed became multicellular
(via sciencedaily.com) Original source A deep dive into macroalgae genetics has uncovered the genetic underpinnings that enabled macroalgae, or 'seaweed,' to evolve multicellularity. Three lineages of macroalgae developed multicellularity independently and during very different time periods by acquiring genes that enable cell adhesion, extracellular matrix formation, and cell differentiation, researchers report. Surprisingly, many of these multicellular-enabling genes had viral origins. The study, which increased the total number of sequenced macroalgal genomes from 14 to 124, is the first to investigate macroalgal evolution through the lens of genomics.
Published First step to untangle DNA: Supercoiled DNA captures gyrase like a lasso ropes cattle
(via sciencedaily.com) Original source Researchers reveal how DNA gyrase resolves DNA entanglements. The findings not only provide novel insights into this fundamental biological mechanism but also have potential practical applications. Gyrases are biomedical targets for the treatment of bacterial infections and the similar human versions of the enzymes are targets for many anti-cancer drugs. Better understanding of how gyrases work at the molecular level can potentially improve clinical treatments.
Published A new spin on organic shampoo makes it sudsier, longer lasting
(via sciencedaily.com) Original source While there's no regulation in the U.S. for what's in organic shampoos, they tend to contain ingredients perceived as safe or environmentally friendly. However, these 'clean' shampoos separate and spoil faster than those made with synthetic stabilizers and preservatives. Now, researchers demonstrate that a simple process -- spinning organic shampoo at high speeds -- improved the final products' shelf lives and ability to clean hair.
Published Nanoscale movies shed light on one barrier to a clean energy future
(via sciencedaily.com) Original source New research is shedding light on one barrier to a clean energy future: corrosion. Using nanoscale imaging techniques, researchers have captured high-resolution videos of tiny crystals of ruthenium dioxide -- a key ingredient used to produce clean-burning hydrogen -- as they are eaten away by their acidic environment. The research could pave the way to more durable catalysts and dramatically extend the lifetime of devices needed to turn hydrogen green.
Published Discovery brings all-solid-state sodium batteries closer to practical use
(via sciencedaily.com) Original source Researchers have developed a mass synthesis process for sodium-containing sulfides. Mass synthesis of electrolytes with high conductivity and formability is key to the practical use of all-solid-state sodium batteries, thought to be safer than lithium-ion batteries and less expensive, as sodium is far more plentiful than lithium.
Published Biofortified rice to combat deficiencies
(via sciencedaily.com) Original source Vitamin B1 is an essential micronutrient for human beings. Its deficiency is the cause of numerous diseases of the nervous and cardiovascular systems. Researchers have achieved a significant advance in the fight against vitamin B1 deficiency, frequently associated with a rice-based diet. By specifically targeting the nourishing tissues of the rice grain, the scientists have succeeded in considerably increasing its vitamin B1 content, without compromising agronomic yield. These results could help solve a major public health problem in regions where rice is the staple food.
Published New strategy for assessing the applicability of reactions
(via sciencedaily.com) Original source Chemists show that a machine-based method prevents widespread 'bias' in chemical publications.
Published Cockayne syndrome: New insights into cellular DNA repair mechanism
(via sciencedaily.com) Original source Researchers decode repair mechanism during transcription of genetic information.
Published Revolutionary molecular device unleashes potential for targeted drug delivery and self-healing materials
(via sciencedaily.com) Original source In a new breakthrough that could revolutionise medical and material engineering, scientists have developed a first-of-its-kind molecular device that controls the release of multiple small molecules using force.
Published New device gathers, stores electricity in remote settings
(via sciencedaily.com) Original source Wirelessly connected devices perform an expanding array of applications, such as monitoring the condition of machinery and remote sensing in agricultural settings. These applications hold much potential for improving the efficiency, but how do you power these devices where reliable electrical sources are not available? Research points to a possible solution in the form of a novel type of battery.
Published Machine learning method reveals chromosome locations in individual cell nucleus
(via sciencedaily.com) Original source Researchers have made a significant advancement toward understanding how the human genome is organized inside a single cell. This knowledge is crucial for analyzing how DNA structure influences gene expression and disease processes.
Published Subterranean storage of hydrogen
(via sciencedaily.com) Original source Scientists are using computer simulations and laboratory experiments to see if depleted oil and natural gas reservoirs can be used for storing carbon-free hydrogen fuel. Hydrogen is an important clean fuel: It can be made by splitting water using solar or wind power, it can be used to generate electricity and power heavy industry, and it could be used to power fuel-cell-based vehicles. Additionally, hydrogen could be stored for months and used when energy needs outpace the supply delivered by renewable energy sources.
