Published Single drop of ethanol to revolutionize nanosensor manufacture
(via sciencedaily.com) Engineers have developed a breakthrough technique to make the processing of nanosensors cheaper, greener and more effective by using a single drop of ethanol to replace heat processing of nanoparticle networks, allowing a wider range of materials to be used to make these sensors.
Published Tropical trees use social distancing to maintain biodiversity
(via sciencedaily.com) Original source Tropical forests can harbor hundreds of species of trees in one square mile. Researchers reveal key factors in the spatial distribution of adult trees.
Published Thermal imaging innovation allows AI to see through pitch darkness like broad daylight
(via sciencedaily.com) Engineers have developed HADAR, or heat-assisted detection and ranging.
Published How heat treatment affects a milk alternative made from rice and coconut water
(via sciencedaily.com) Whether they're made from soybeans, almonds, oats, or just sourced straight from the cow, milk products must go through heat treatment to prevent harmful bacterial growth and keep them safe. But understanding how these processes affect new, plant-based milk formulations could make the beverages more pleasant to drink as well. Researchers have discovered how pasteurization and sterilization affects the look and feel of one such drink made from coconut and rice.
Published Plans to plant billions of trees threatened by massive undersupply of seedlings
(via sciencedaily.com) Original source Major government and private funding is being invested in planting trees as a powerful tool to fight climate change. But new research shows a troubling bottleneck that could threaten these efforts: U.S. tree nurseries don't grow close to enough trees--nor have the species diversity needed--to meet ambitious planting and restoration goals.
Published Way cool: 'freeze ray' technology
(via sciencedaily.com) An unusual discovery is now being developed as an on-demand cooling solution for high-flying military electronics.
Published Fusion model hot off the wall
(via sciencedaily.com) Heat load mitigation is critical to extending the lifetime of future fusion device. Researchers have found a way to explain the rotational temperatures measured in three different experimental fusion devices in Japan and the United States. Their model evaluates the surface interactions and electron-proton collisions of hydrogen molecules.
Published New study reveals that tree species diversity increases spider density
(via sciencedaily.com) Original source The link between tree diversity and spider populations can help homeowners and other land managers better plan tree plantings to naturally mitigate the effects of climate change.
Published Research supports use of managed and prescribed fires to reduce fire severity
(via sciencedaily.com) Original source Scientists found that fires in America's dry conifer forests are burning hotter and killing more trees today than in previous centuries. The main culprit? Paradoxically, a lack of fires.
Published Novel thermal sensor could help drive down the heat
(via sciencedaily.com) Excess heat from electronic or mechanical devices is a sign or cause of inefficient performance. In many cases, embedded sensors to monitor the flow of heat could help engineers alter device behavior or designs to improve their efficiency. For the first time, researchers exploit a novel thermoelectric phenomenon to build a thin sensor that can visualize heat flow in real time. The sensor could be built deep inside devices where other kinds of sensors are impractical. It is also quick, cheap and easy to manufacture using well-established methods.
Published Miocene period fossil forest of Wataria found in Japan
(via sciencedaily.com) Original source An exquisitely preserved fossil forest from Japan provides missing links and helps reconstruct a whole Eurasia plant from the late Miocene epoch.
Published Gene variation makes apple trees 'weep,' improving orchards
(via sciencedaily.com) Original source Plant geneticists have identified a mutation in a gene that causes the 'weeping' architecture -- branches growing downwards -- in apple trees, a finding that could improve orchard fruit production.
Published Catalyst can control methane emissions in natural gas engines
(via sciencedaily.com) A catalyst using a single or just a few palladium atoms removed 90% of unburned methane from natural gas engine exhaust at low temperatures in a recent study. While more research needs to be done, the advance in single atom catalysis has the potential to lower exhaust emissions of methane, one of the worst greenhouse gases that traps heat at about 25 times the rate of carbon dioxide. Researchers showed that the single-atom catalyst was able to remove methane from engine exhaust at lower temperatures, less than 350 degrees Celsius (662 degrees Fahrenheit), while maintaining reaction stability at higher temperatures.
Published A non-covalent bonding experience
(via sciencedaily.com) Putting a suite of new materials synthesis and characterization methods to the test, a team of scientists has developed 14 organic-inorganic hybrid materials, seven of which are entirely new.
Published Droplet levitation is a new way to explore airborne viruses and microorganisms
(via sciencedaily.com) Researchers report achieving self-sustaining and long-term levitation of millimeter-sized droplets of several different liquids without any external forces. To get the droplets to levitate, they use solutocapillary convection, which occurs when a surface tension gradient is formed by nonuniform distribution of vapor molecules from the droplet at the pool surface. Further exploring the effects of various external conditions on self-sustained droplet levitation will reveal whether it can be harnessed and adapted for microbiology and biochemistry applications.
Published Small-winged and lighter colored butterflies likely to be at greatest threat from climate change
(via sciencedaily.com) Small-winged and lighter colored butterflies likely to be at greatest threat from climate change. The family, wing length and wing colour of tropical butterflies all influence their ability to withstand rising temperatures, say ecologists. The researchers believe this could help identify species whose survival is under threat from climate change.
Published Building a better forest tree with CRISPR gene editing
(via sciencedaily.com) Original source Researchers use CRISPR techniques to modify lignin levels in poplar trees.
Published Thermal cloak passively keeps electric vehicles cool in the summer and warm in the winter
(via sciencedaily.com) When an electric vehicle is parked outside, its temperature can swing wildly from day to night and season to season, which can lead to deterioration of the battery. To dampen these fluctuations and extend the battery's lifespan, researchers have designed an all-season thermal cloak that can cool an electric vehicle by 8°C on a hot day and warm it by 6.8°C at night. The cloak, made predominantly of silica and aluminum, can do so passively without outside energy input and operates without any modification between hot or cold weather.
Published The ground is deforming, and buildings aren't ready
(via sciencedaily.com) A new study has linked underground climate change to the shifting ground beneath urban areas. The phenomenon is affecting all major urban areas around the globe, causing civil structures and infrastructures to crack.
Published Forest can adapt to climate change, but not quickly enough
(via sciencedaily.com) Original source America's forests have a tough time in store for them. Climate change is increasing temperatures and decreasing moisture levels across the country, not a winning combination for trees.
