The world’s best supercomputers are being updated to run AI software faster

Posted by in categories: climatology, robotics/AI, supercomputing

The upgrades include changes to make AI programming simpler—and to speed up powerful machines for specific AI tasks.

The news: The International Supercomputing Conference (ISC) kicked off in Frankfurt yesterday with the release of the latest list of the 500 most powerful supercomputers in the world. US machines still top the ranking, but China has the most computers on the list (219 versus 116 for the US).

Supercomputers have already turbocharged some AI applications. For example. the US’s Summit supercomputer (pictured above), which leads the Top 500, has already run a complex machine-learning model for climate research faster than any other machine.

Fossil study finds lightning is strong enough to power a billion homes

Posted by in category: climatology

An expert from the University of South Florida deduced how big a bolt of lightning was based on the size of rocks formed by lightning.

When lightning strikes sand it creates a new type of rock, called fulgurite – a hollow tube formed as the lightning travels through the sand, vaporizing it and melting its outer edges.

Researchers determined that on average, the energy required to form these rocks was at least about one megajoule per meter of fulgurite formed.

Can We Harvest Lightning For The Power Grid?

Posted by in category: climatology

By New Scientist, An Energy Realities Partner

Nobody has all the answers to the world’s energy questions, so New Scientist has teamed up with Statoil to search for solutions from New Scientist’s audience.

The question posed was: How much energy is in a lightning bolt? Is it enough, and are there places where lightning strikes often enough, to think about flying kites to transfer that energy to the grid?

A bean for all seasons?

Posted by in category: climatology

Biology professor and researcher Christopher Cullis said he pondered two big questions when he first caught sight of the wild marama bean plant, its definitive patches of green leaves standing out in contrast from among an otherwise parched and brown Namibian landscape.

“Why isn’t this plant affected by the lack of water like everything else—and why isn’t it being eaten by any wildlife?” Cullis said, turning one of the walnut-sized beans over in his fingers and recalling his first trip to the coastal southwest African country about a decade ago. “The answers to those questions make this a very interesting and important legume.”

Caltech reactor could convert CO2 into breathable oxygen for space trips

Posted by in categories: climatology, space, sustainability

Although oxygen is common throughout the cosmos, most of it isn’t in the form that we as humans need to breathe – molecular oxygen, or O2. Now, researchers at Caltech claim to have created a reactor that can turn carbon dioxide into molecular oxygen, which could help us fight climate change here on Earth or generate oxygen for life in space.

A month after the fire that ravaged the Notre Dame Cathedral in Paris

Posted by in categories: climatology, government

A month after the fire that ravaged the Notre Dame Cathedral in Paris, scientists and research bodies are getting organized to help restore the building—and advance scientific knowledge.

At a public hearing held yesterday by France’s Parliamentary Office for the Evaluation of Scientific and Technological Options (OPECST), academics explained how they can contribute to the government’s efforts to restore the cathedral, which was partly destroyed on 15 April.

“This catastrophe is, in the end, a privileged moment for research, because we’ll have access to materials that we otherwise wouldn’t be able to access,” said Martine Regert, deputy scientific director of the Institute of Ecology and Environment at the French national research agency CNRS. For example, analyzing certain isotopes in the cathedral’s timber frame could provide insights about the medieval climate, said Philippe Dillmann, a research leader at CNRS’s Institute for Research on Archeomaterials.
