Published First 'warm-blooded' dinosaurs may have emerged 180 million years ago
(via sciencedaily.com)
Original source 
The ability to regulate body temperature, a trait all mammals and birds have today, may have evolved among some dinosaurs early in the Jurassic period about 180 million years ago. The new study looked at the spread of dinosaurs across different climates on Earth throughout the Mesozoic Era (the dinosaur era lasting from 230 to 66 million years ago), drawing on 1,000 fossils, climate models and the geography of the period, and dinosaurs' evolutionary trees.
Published Next-generation sustainable electronics are doped with air
(via sciencedaily.com)
Original source 
Semiconductors are the foundation of all modern electronics. Now, researchers have developed a new method where organic semiconductors can become more conductive with the help of air as a dopant. The study is a significant step towards future cheap and sustainable organic semiconductors.
Published Bio-based resins could offer recyclable future for 3D printing
(via sciencedaily.com)
Original source 
A new type of recyclable resin, made from biosourced materials, has been designed for use in 3D printing applications.
Published Penalties for dropping out of ecosystem services incentive programs should equal lost environmental benefits
(via sciencedaily.com)
Original source 
PES programs are currently structured in ways that could limit their participation or create incentives to drop out before the full environmental benefits are realized.
Published Promising new development in solar cell technology
(via sciencedaily.com)
Original source 
Researchers who contributed to the development of record-breaking solar cells a few years ago, expanded their invention. The self-assembled monolayers can now be applied not only in inverted but also in regular structure perovskite solar cells.
Published Scientists generate heat over 1,000 degrees Celsius with solar power instead of fossil fuel
(via sciencedaily.com)
Original source 
Instead of burning fossil fuels to smelt steel and cook cement, researchers in Switzerland want to use heat from the sun. The proof-of-concept study uses synthetic quartz to trap solar energy at temperatures over 1,000 C (1,832 F), demonstrating the method's potential role in providing clean energy for carbon-intensive industries.
Published The case for sharing carbon storage risk
(via sciencedaily.com)
Original source 
Even the most optimistic projections for the rapid build-out of solar, wind, and other low-carbon resources acknowledge that coal, natural gas, and other fossil fuels will dominate the world's energy mix for decades to come. If the vast greenhouse gas emissions from burning these fossil fuels continue to enter the planet's atmosphere, global warming will not be limited to sustainable levels. The capture and geologic sequestration of carbon emissions (CCS) offer a promising solution to the world's carbon conundrum.
Published Genetics provide key to fight crown-of-thorns starfish
(via sciencedaily.com)
Original source 
Scientists are one step closer to combating coral-destroying crown-of-thorns starfish, following a study into the pest's genetics.
Published Most dangerous areas for whale shark-shipping vessel collisions revealed
(via sciencedaily.com)
Original source 
Heavily-used shipping lanes that pass through whale shark feeding grounds pose a threat to the species, according to scientists who have revealed areas where the creatures are at the highest risk.
Published Meet the new insect killing Utah's fir trees
(via sciencedaily.com)
Original source 
The balsam woolly adelgid, a tiny nonnative flightless insect, is spreading across the American West killing subalpine fir in northern Utah's recreation-heavy mountain ranges and canyons. Rsearchers document a close association between the pest's spread and warming temperatures.
Published Scientists develop an affordable sensor for lead contamination
(via sciencedaily.com)
Original source 
A new system could enable simple, low-cost detectors for monitoring water for lead contamination, and potentially other heavy metals as well.
Published Far from toxic, lactate rivals glucose as body's major fuel after a carbohydrate meal
(via sciencedaily.com)
Original source 
Scientists have documented the benefits of lactate burning in exercising humans, but few studies have looked at the role of lactate during rest or after a meal. Exercise physiologists challenged fasting men and women with a carbohydrate meal and then monitored lactate in the blood and fat vs carbohydrate metabolism. They found that lactate buffers glucose from a meal, and that lactate is utilized for energy almost as much as glucose.
Published Simulating diffusion using 'kinosons' and machine learning
(via sciencedaily.com)
Original source 
Researchers have recast diffusion in multicomponent alloys as a sum of individual contributions, called 'kinosons.' Using machine learning to compute the statistical distribution of the individual contributions, they were able to model the alloy and calculate its diffusivity orders of magnitude more efficiently than computing whole trajectories.
Published Petroleum, chlorine mix could yield harmful byproducts
(via sciencedaily.com)
Original source 
A new study shows that chlorine mixed with petroleum in water can potentially produce inadvertent byproducts harmful to human health.
Published Researchers uncover what makes some chickens more water efficient than others
(via sciencedaily.com)
Original source 
Research indicates a specially bred line of chickens could save growers thousands of gallons of water and thousands of pounds of food each month without sacrificing poultry health.
Published Study tallies heatwave deaths over recent decades
(via sciencedaily.com)
Original source 
Between 1990 and 2019, more than 150,000 deaths around the globe were associated with heatwaves each year, according to a new study.
Published Virus that causes COVID-19 can penetrate blood-retinal barrier and could damage vision
(via sciencedaily.com)
Original source 
Researchers have discovered the virus that causes COVID-19 can breach the protective blood-retinal-barrier with potential long-term consequences in the eye.
Published Virtual reality becomes more engaging when designers use cinematic tools
(via sciencedaily.com)
Original source 
Cinematography techniques can significantly increase user engagement with virtual environments and, in particular, the aesthetic appeal of what users see in virtual reality.
Published 90% of Floridians believe climate change is happening
(via sciencedaily.com)
Original source 
The latest 'Florida Climate Resilience Survey' found that 90% of Floridians believe that climate change is happening. Belief in human-caused climate change has surged among Florida Independents while slipping among Republicans in the state since last fall. But despite these changes, the survey found enduring support among Floridians for increased government action to address the consequences of a warming planet. The survey found 68% of all respondents want state government to do more and 69% want the federal government to do more to address climate change.
Published Metalens expands Its reach from light to sound
