Untangling the origins of Beelzebufo — the giant frog that lived alongside the dinosaurs — turns out to be one of the most bedeviling problems in the history of amphibians.

Thank you to these paleoartists for allowing us to use their wonderful illustrations:

Researchers link end of Green Sahara with Southeast Asia megadrought.

Physical evidence found in caves in Laos helps tell a story about a connection between the end of the Green Sahara — when once heavily vegetated Northern Africa became a hyper-arid landscape — and a previously unknown megadrought that crippled Southeast Asia 4,000 to 5,000 years ago.

In a paper published today in Nature Communications, scientists at the University of California, Irvine, the University of Pennsylvania, William Paterson University of New Jersey and other international institutions explain how this major climate transformation led to a shift in human settlement patterns in Southeast Asia, which is now inhabited by more than 600 million people.

Soaring temperatures, intensified flood risks and heightened water stress will threaten 57 U.S. nuclear plants over the next 20 years, forcing operators to take additional resiliency measures, according to a new report.

“The consequences of climate change can affect every aspect of nuclear plant operations—from fuel handling and power and steam generation to maintenance, safety systems and waste processing,” said the analysis, which was published yesterday by Moody’s Investors Service.

A team of researchers working at the University of Maryland has uncovered the structure of the mysterious blue whirling flame. In their paper published in the journal Science Advances, the group describes using computer simulations to determine the structure of the unique type of flame.

Back in 2016, a team of researchers discovered what they described as a blue whirling flame while they were studying the properties of liquid fuel floating on water. They had added fuel to a tank full of water that was enclosed in a space that generated a vortex. They described a fire that looked at first like a tornado, but then shortly after, settled into what they dubbed a blue whirling flame. They noted at the time that its color suggested it likely was very efficient, burning the fuel without creating soot—a property that might be useful in cleaning up oil spills. Since then, others have looked at the unique type of flame, but no one had tried to understand its structure. In this new effort, the researchers took a closer look at the flame and found it was actually three types of flames that had merged into one.

To learn more about the nature of the blue whirling flame, the researchers created computer simulations using conditions known to generate them. They then slowly adjusted the parameters until they were able to generate the flame virtually. They discovered that the flame was actually the result of three known types of flames merging: those with an invisible outer flame, which happens when there is less fuel than oxygen in the mix—and two that had types of visible inner flames in which higher fuel ratios are more common.

NASA researchers have observed “superbolts” of lightning in Jupiter’s atmosphere, which form in clouds made of water and ammonia.

These guys have a great idea…but In true Zuckerberg style how does one steal and supercharge the idea. With food having salmonella, people need to grow more food at home. What technology can be created that uses technology to help people in urban settings grow their own food. This will help many in a post covid world, and the food should be safer, and also may promote nutrition. nnAmerican farmers also are having trouble, and would see the loss in demand. Global food production needs to increase. Japan offered to boost the continent of Africa’s rice production through cooperation. The same cooperation needs to be done with American farmers to boost Africa’s food production. Technology would be used to partner American farmers with African village cooperatives. The farmers and cooperatives would work together and share profits. This way the American farmer has revenue coming from two markets and continents. The same model can also be used in Mexico to prevent immigration. This way American farmers would also have revenue coming from Central and South America, however people who normally would be farm workers would be partners, and make more than they would having to cross borders dangerously, to make less money. This model can both reduce poverty, as well and insure food security. The capital for investment would have to come from many sources. Crowdfunding is one that can be good as the money can be paid back with profit. This way a crowd fund investment would gain better returns than interest rates. The next of course would be USAID. A project can be developed, in which USAID provides American farmers with start up capital. They manage the project pay back the loans, while sharing profits. Agreements can be developed for certain periods of time, After which the American farmer turns the project over to the cooperatives…just thinking out of the box it is a bit crazy. The farmers would be like a new Peace Corps thing. #VillageEconomics nnPortfolio company #ApolloAgriculture was recently featured in a Forbes article highlighting their machine-learning and automated-operations technology that helps small-scale farmers access everything they need to maximize their profitability. #impactinvesting #agtech

Between 2011 and 2014, engineer and Stanford grad Eli Pollak worked in agricultural technology in the U.S. for a company called the Climate Corporation. The enterprise where he was one of the early employees (which in 2013 was acquired by Monsanto for over $1 billion) worked on providing customized recommendations to increase production of large scale commercial farmers. What caught Pollak’s eye during his tenure at the company, however, was that some countries were planting way more seeds, but producing dramatically less agricultural products than the U.S.

This prompted Pollak to team up with Climate Corporation colleague Earl St Sauver, and Benjamin Ngenga (who himself grew up on a farm) to start Apollo Agriculture, a Kenyan ag-tech company which uses machine learning and automated operations technology to help small-scale farmers access everything they need to maximize their profitability.

Great interview with planetary scientist Isaac Smith, an expert on Mars polar science at York University in Toronto. Well worth a listen.

Three spacecraft are currently en route to Mars, but none will visit the poles. Yet Mars’ poles drive much of the Martian climate. And their understanding is key to deciphering what might have been happening on the Red planet some 3.5 billion years ago when it had lakes, deltas, rivers, and perhaps even transient oceans. I’m very pleased to welcome planetary scientist Isaac B. Smith of York University in Toronto — an expert on Mars polar science and exploration — to discuss the need for a Martian polar lander as well as a broader look at Mars science.

Imagine tiny crystals that “blink” like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels.

A Rutgers-led team has created ultra-small titanium dioxide crystals that exhibit unusual “blinking” behavior and may help to produce methane and other fuels, according to a study in the journal Angewandte Chemie. The crystals, also known as nanoparticles, stay charged for a long time and could benefit efforts to develop quantum computers.

“Our findings are quite important and intriguing in a number of ways, and more research is needed to understand how these exotic crystals work and to fulfill their potential,” said senior author Tewodros (Teddy) Asefa, a professor in the Department of Chemistry and Chemical Biology in the School of Arts and Sciences at Rutgers University-New Brunswick. He’s also a professor in the Department of Chemical and Biochemical Engineering in the School of Engineering.

“We need to go to space to help us here on Earth. Satellites have played an enormous role in improving the state of the world, and will do even more”.

I’m often asked: ‘Why are you building satellites for space when there are so many problems to fix here on Earth?’ It’s a perfectly rational question. The short answer is that we need to go to space to help us here on Earth. Satellites have played an enormous role in improving the state of the world, and will do even more as an explosion of technology innovation enables large new fleets of small satellites to be deployed with radical new capabilities.
