Published Material would allow users to 'tune' windows to block targeted wavelengths of light
(via sciencedaily.com) Researchers have demonstrated a material for next generation dynamic windows, which would allow building occupants to switch their windows between three modes: transparent, or 'normal' windows; windows that block infrared light, helping to keep a building cool; and tinted windows that control glare while maintaining the view.
Published Exercise and muscle regulation: Implications for diabetes and obesity
(via sciencedaily.com) Original source How do our muscles respond at the molecular level to exercise? Researchers have unraveled the cellular basis and signaling pathways responsible for the positive impact of physical activity on our overall health. Regulatory T cells, a type of immune cell, play a critical role in ensuring proper muscle function. These novel insights are paving the path towards precision medicines targeting metabolic disorders like obesity and diabetes, as well as muscle-related illnesses.
Published Sustainable energy for aviation: What are our options?
(via sciencedaily.com) Scientists and industry leaders worldwide are looking for answers on how to make aviation sustainable by 2050 and choosing a viable sustainable fuel is a major sticking point. Aerospace engineers took a full inventory of the options to make a data-driven assessment about how they stack up in comparison. He reviewed over 300 research projects from across different sectors, not just aerospace, to synthesize the ideas and draw conclusions to help direct the dialogue about sustainable aviation toward a permanent solution.
Published Genetically modifying individual cells in animals
(via sciencedaily.com) Original source Researchers have developed a method that lets them genetically modify each cell differently in animals. This allows them to study in a single experiment what used to require many animal experiments. Using the new method, the researchers have discovered genes that are relevant for a severe rare genetic disorder.
Published Efficient next-generation solar panels on horizon following breakthrough
(via sciencedaily.com) A scientific breakthrough brings mass production of the next generation of cheaper and lighter perovskite solar cells one step closer.
Published Artificial Intelligence tools shed light on millions of proteins
(via sciencedaily.com) Original source A research team has uncovered a treasure trove of uncharacterized proteins. Embracing the recent deep learning revolution, they discovered hundreds of new protein families and even a novel predicted protein fold.
Published Sometimes beneficial, sometimes damaging: The double role of the enzyme chameau
(via sciencedaily.com) Original source Biologists have discovered why an enzyme is important for the survival of fruit flies, even though it can shorten their lives under certain conditions.
Published Plant and forest researchers do not 'anthropomorphize' plants
(via sciencedaily.com) Original source Plants are often attributed with abilities similar to those known in the animal or human world. Trees are said to have feelings and can therefore care for their offspring, like mothers. Researchers analyzed the claims in two popular publications on forests and reached the conclusion that conjecture is equated with fact. They warn against 'anthropomorphizing' plants.
Published A newly identified virus emerges from the deep
(via sciencedaily.com) Original source Marine virologists analyzed sediment from the Mariana Trench, the deepest place on Earth, and identified a new bacteriophage.
Published Spider silk is spun by silkworms for the first time, offering a green alternative to synthetic fibers
(via sciencedaily.com) Scientists have synthesized spider silk from genetically modified silkworms, producing fibers six times tougher than the Kevlar used in bulletproof vests. The study is the first to successfully produce full-length spider silk proteins using silkworms. The findings demonstrate a technique that could be used to manufacture an environmentally friendly alternative to synthetic commercial fibers such as nylon.
Published Newfound brain circuit explains why infant cries prompt milk release
(via sciencedaily.com) Original source Hearing the sound of a newborn's wail can trigger the release of oxytocin, a brain chemical that controls breast-milk release in mothers, a new study in rodents shows. Researchers found that once prompted, this flood of hormones continues for roughly five minutes before tapering off, enabling mothers to feed their young until they are sated or begin crying again.
Published Imaging the smallest atoms provides insights into an enzyme's unusual biochemistry
(via sciencedaily.com) A team has used neutron crystallography to image all of the atoms in a radical intermediate of a copper amine oxidase enzyme. They disclosed previously unknown details, such as precise conformational changes, that help to explain the enzyme's biochemistry. This work might help researchers engineer enzymes that facilitate unusual chemistry or are highly efficient at room temperature that are useful in chemical industry.
Published Electrons take flight at the nanoscale
(via sciencedaily.com) A study showing how electrons flow around sharp bends, such as those found in integrated circuits, has the potential to improve how these circuits, commonly used in electronic and optoelectronic devices, are designed.
Published Fast-track strain engineering for speedy biomanufacturing
(via sciencedaily.com) Using engineered microbes as microscopic factories has given the world steady sources of life-saving drugs, revolutionized the food industry, and allowed us to make sustainable versions of valuable chemicals previously made from petroleum. But behind each biomanufactured product on the market today is the investment of years of work and many millions of dollars in research and development funding. Scientists want to help the burgeoning industry reach new heights by accelerating and streamlining the process of engineering microbes to produce important compounds with commercial-ready efficiency.
Published Yogurt may be the next go-to garlic breath remedy
(via sciencedaily.com) Original source A new study conducted in a lab -- with follow-up human breath tests being planned -- showed that whole milk plain yogurt prevented almost all of the volatile compounds responsible for garlic's pungent scent from escaping into the air.
Published Combustion powers bug-sized robots to leap, lift and race
(via sciencedaily.com) Researchers combined soft microactuators with high-energy-density chemical fuel to create an insect-scale quadrupedal robot that is powered by combustion and can outrace, outlift, outflex and outleap its electric-driven competitors.
Published Cheap and efficient catalyst could boost renewable energy storage
(via sciencedaily.com) Storing renewable energy as hydrogen could soon become much easier thanks to a new catalyst based on single atoms of platinum.
Published Engineers grow full wafers of high-performing 2D semiconductor that integrates with state-of-the-art chips
(via sciencedaily.com) Researchers have grown a high-performing 2D semiconductor to a full-size, industrial-scale wafer. In addition, the semiconductor material, indium selenide (InSe), can be deposited at temperatures low enough to integrate with a silicon chip.
Published How wind turbines react to turbulence
(via sciencedaily.com) The output of wind turbines can rise or fall by 50 per cent in a matter of seconds. Such fluctuations in the megawatt range put a strain on both power grids and the turbines themselves. A new study presents a new stochastic method that could help to mitigate these sudden swings and achieve a more consistent electricity production.
Published Scientists develop method to detect deadly infectious diseases
(via sciencedaily.com) Researchers have developed a way of detecting the early onset of deadly infectious diseases using a test so ultrasensitive that it could someday revolutionize medical approaches to epidemics. The test is an electronic sensor contained within a computer chip. It employs nanoballs -- microscopic spherical clumps made of tinier particles of genetic material -- and combines that technology with advanced electronics.
