Game changers in fighting climate change: Refuels are suitable for everyday use      (via sciencedaily.com) 

Synthetic fuels produced from renewable sources, so-called refuels, are deemed potential game changers in fighting climate change. Refuels promise to reduce CO2 emissions by up to 90% compared to conventional fuels and they allow for the continued use of existing vehicle fleets with combustion engines and of the refueling infrastructure, from fuel production to transport to sales. Researchers carried out extensive fleet tests in a large-scale project with industry partners and proved that refuels can be used in all vehicles and produced in large quantities in the foreseeable future.

Why some countries are leading the shift to green energy      (via sciencedaily.com) 

A new study identifies the political factors that allow some countries to lead in adopting cleaner sources of energy while others lag behind. By analyzing how different countries responded to the current energy crisis and to the oil crisis of the 1970s, the study reveals how the structure of political institutions can help or hinder the shift to clean energy. The findings offer important lessons as governments race to limit the impacts of climate change.

Process converts polyethylene bags, plastics to polymer building blocks      (via sciencedaily.com) 

Polyethylene plastics -- single-use bags and general-purpose bottles -- are indestructable forever plastics. That also makes them hard to recycle. Chemists have found a way to break down the polymer -- a chain of about a thousand ethylene molecules -- into three-carbon molecules, propylene, which are in high demand for making another plastic, polypropylene. The process could turn waste plastic into high-value feedstocks and reduce the need for fossil fuels to make propylene.

Scientists improve process for turning hard-to-recycle plastic waste into fuel      (via sciencedaily.com) 

Turning plastic waste into useful products through chemical recycling is one strategy for addressing Earth's growing plastic pollution problem. A new study may improve the ability of one method, called pyrolysis, to process hard-to-recycle mixed plastics -- like multilayer food packaging -- and generate fuel as a byproduct, the scientists said.

Catalytic process with lignin could enable 100% sustainable aviation fuel      (via sciencedaily.com) 

An underutilized natural resource could be just what the airline industry needs to curb carbon emissions. Researchers report success in using lignin as a path toward a drop-in 100% sustainable aviation fuel. Lignin makes up the rigid parts of the cell walls of plants. Other parts of plants are used for biofuels, but lignin has been largely overlooked because of the difficulties in breaking it down chemically and converting it into useful products.

Shaking the dinosaur family tree: How did 'bird-hipped' dinosaurs evolve?      (via sciencedaily.com) 

Researchers have conducted a new analysis of the origins of 'bird-hipped' dinosaurs -- the group which includes iconic species such as Triceratops -- and found that they likely evolved from a group of animals known as silesaurs, which were first identified two decades ago.

Rooftop solar cells can be a boon for water conservation too      (via sciencedaily.com) 

Electricity-generating rooftop solar cells not only save on planet-warming carbon emissions, they also save a significant amount of water. Water consumption is tightly bound to energy use, because without water we cannot mine, drill, frack, or cool thermoelectric and nuclear plants. A given household may save on average 16,200 gallons of water per year by installing rooftop solar.

Discovery of extinct prehistoric reptile that lived among dinosaurs      (via sciencedaily.com) 

Researchers have discovered a new extinct species of lizard-like reptile that belongs to the same ancient lineage as New Zealand's living tuatara. A team of scientists describe the new species Opisthiamimus gregori, which once inhabited Jurassic North America about 150 million years ago alongside dinosaurs like Stegosaurus and Allosaurus. In life, this prehistoric reptile would have been about 16 centimeters (about 6 inches) from nose to tail -- and would fit curled up in the palm of an adult human hand -- and likely survived on a diet of insects and other invertebrates.

New laser-based instrument designed to boost hydrogen research      (via sciencedaily.com) 

Researchers have developed an analytical instrument that uses an ultrafast laser for precise temperature and concentration measurements of hydrogen. Researchers describe a new coherent Raman spectroscopy instrument, made possible due to a setup that converts broadband light from a laser with short (femtosecond) pulses into extremely short supercontinuum pulses, which contain a wide range of wavelengths. Their new approach could help advance the study of greener hydrogen-based fuels for use in spacecraft and airplanes.

What killed dinosaurs and other life on Earth?      (via sciencedaily.com) 

Determining what killed the dinosaurs 66 million years ago at the end of the Cretaceous Period has long been the topic of debate, as scientists set out to determine what caused the five mass extinction events that reshaped life on planet Earth in a geological instant. Some scientists argue that comets or asteroids that crashed into Earth were the most likely agents of mass destruction, while others argue that large volcanic eruptions were the cause. A new study reports that volcanic activity appears to have been the key driver of mass extinctions.

Sulfur shortage: A potential resource crisis looming as the world decarbonizes      (via sciencedaily.com) 

A new study highlights that global demand for sulfuric acid is set to rise significantly from '246 to 400 million tons' by 2040 -- a result of more intensive agriculture and the world moving away from fossil fuels. A projected shortage of sulfuric acid, a crucial chemical in our modern industrial society, could stifle green technology advancement and threaten global food security, according to a new study.
