Published Can hydrogels help mend a broken heart?
(via sciencedaily.com) Original source You can mend a broken heart this valentine s day now that researchers invented a new hydrogel that can be used to heal damaged heart tissue and improve cancer treatments.
Published The hidden rule for flight feathers -- and how it could reveal which dinosaurs could fly
(via sciencedaily.com) Original source Scientists examined hundreds of birds in museum collections and discovered a suite of feather characteristics that all flying birds have in common. These 'rules' provide clues as to how the dinosaur ancestors of modern birds first evolved the ability to fly, and which dinosaurs were capable of flight.
Published Not only in information technology: Restart also works in chemical simulations
(via sciencedaily.com) Original source Scientists have discovered that a known practice in information technology can also be applied to chemistry. Researchers found that to enhance the sampling in chemical simulations, all you need to do is stop and restart.
Published Key advance for capturing carbon from the air
(via sciencedaily.com) Original source A chemical element so visually striking that it was named for a goddess shows a 'Goldilocks' level of reactivity -- neither too much nor too little -- that makes it a strong candidate as a carbon scrubbing tool.
Published Why insects navigate more efficiently than robots
(via sciencedaily.com) Original source Engineers have studied how insects navigate, for the purpose of developing energy-efficient robots.
Published Sensors made from 'frozen smoke' can detect toxic formaldehyde in homes and offices
(via sciencedaily.com) Original source Researchers have developed a sensor made from 'frozen smoke' that uses artificial intelligence techniques to detect formaldehyde in real time at concentrations as low as eight parts per billion, far beyond the sensitivity of most indoor air quality sensors.
Published Conversion process turns greenhouse gas into ethylene
(via sciencedaily.com) Original source Engineers have created a more efficient way of converting carbon dioxide into valuable products while simultaneously addressing climate change.
Published Towards A Better Way of Releasing Hydrogen Stored in Hydrogen Boride Sheets
(via sciencedaily.com) Original source Hydrogen stored in hydrogen boride sheets can be efficiently released electrochemically, report scientists. Through a series of experiments, they demonstrated that dispersing these sheets in an organic solvent and applying a small voltage is enough to release all the stored hydrogen efficiently. These findings suggest hydrogen boride sheets could soon become a safe and convenient way to store and transport hydrogen, which is a cleaner and more sustainable fuel.
Published Surprising behavior in one of the least studied mammals in the world
(via sciencedaily.com) Original source Beaked whales are among the least studied mammals in the world. Now, a new study reveals surprising information about the Baird's beaked whale species.
Published Molecular manganese complex as superphotooxidant
(via sciencedaily.com) Original source Highly reducing or oxidizing photocatalysts are a fundamental challenge in photochemistry. Only a few transition metal complexes with Earth-abundant metal ions have so far advanced to excited state oxidants, including chromium, iron, and cobalt. All these photocatalysts require high energy light for excitation and their oxidizing power has not yet been fully exploited. Furthermore, precious and hence expensive metals are the decisive ingredients in most cases. A team of researchers has now developed a new molecular system based on the element manganese. Manganese, as opposed to precious metals, is the third most abundant metal after iron and titanium and hence widely available and very cheap.
Published Alien invasion: Non-native earthworms threaten ecosystems
(via sciencedaily.com) Original source Analysis reveals imported earthworm species have colonized large swaths of North America, and represent a largely overlooked threat to native ecosystems. The researchers warn of the need to better understand and manage the invaders in our midst.
Published New process allows full recovery of starting materials from tough polymer composites
(via sciencedaily.com) Original source In a win for chemistry, inventors have designed a closed-loop path for synthesizing an exceptionally tough carbon-fiber-reinforced polymer and later recovering all of its starting materials.
Published Researchers unveil method to detect 'forever chemicals' in under 3 minutes
(via sciencedaily.com) Original source PFAS have earned the name 'forever chemicals' with good reason -- the human-made compounds, which can take thousands of years to degrade and are found in everything from grease-resistant food packaging to water-repellent clothing, have made their way into nearly half the U.S. tap water supply.
Published Foul fumes pose pollinator problems
(via sciencedaily.com) Original source Scientists have discovered that nighttime air pollution -- coming primarily form car exhaust and power plant emissions -- is responsible for a major drop in nighttime pollinator activity. Nitrate radicals (NO3) in the air degrade the scent chemicals released by a common wildflower, drastically reducing the scent-based cues that its chief pollinators rely on to locate the flower. The findings show how nighttime pollution creates a chain of chemical reactions that degrades scent cues, leaving flowers undetectable by smell. The researchers also determined that pollution likely has worldwide impacts on pollination.
Published Nanofiber bandages fight infection, speed healing
(via sciencedaily.com) Original source Researchers have identified a new way to harness the antioxidant and antibacterial properties of a botanical compound to make nanofiber-coated cotton bandages that fight infection and help wounds heal more quickly.
Published Greenhouse gas repurposed
(via sciencedaily.com) Original source Cutting-edge research converted waste carbon dioxide into a potential precursor for chemicals and carbon-free fuel.
Published Scientists develop artificial 'worm gut' to break down plastics
(via sciencedaily.com) Original source A team of scientists has developed an artificial 'worm gut' to break down plastics, offering hope for a nature-inspired method to tackle the global plastic pollution problem.
Published Surprise discovery of tiny insect-killing worm
(via sciencedaily.com) Original source Scientists have discovered a tiny worm species that infects and kills insects. These worms, called nematodes, could control crop pests in warm, humid places where other beneficial nematodes are currently unable to thrive.
Published How fruit flies control the brain's 'steering wheel'
(via sciencedaily.com) Original source A newly discovered neural circuit mediates between navigational brain cells, acting as a sort of mental steering wheel.
Published Replacing animal-based foods with alternative proteins would unlock land for carbon removal
(via sciencedaily.com) Original source Researchers report that replacing 50% of animal products with alternative proteins by 2050 could free up enough agricultural land to generate renewable energy equivalent in volume to today's coal-generated power while simultaneously removing substantial CO2 from the atmosphere.
