NASA’s Juno spacecraft has spotted short bursts that make up lightning bolts on Jupiter, showing that Jovian lightning works in much the same way as it does on Earth.

An underwater volcanic eruption last year was powerful enough to generate plasma bubbles that disrupted radio communications in outer space, a new study finds.
The new results could lead to ways to avoid satellite and GPS disruptions on Earth, and to learn more about volcanoes on alien worlds, scientists added.
The slug may be vibrant and rare, but experts believe we’ll be seeing more of them as they adapt to warming waters thanks to climate change.
It “lasts more than three times as long” as lithium-ion, according to EnerVenue CEO Jorg Heinemann.
With the advent of space tourism for the world’s wealthiest and a looming global recession, there has been a predictable increase in arguments against public spending on space technologies.
However, those calling to halt space operations often ignore the immense benefits space technologies bring us here on Earth. Obvious examples come in the form of GPS and the many satellites used to investigate the effects of climate change.
High-performance computing (HPC) has become an essential tool for processing large datasets and simulating nature’s most complex systems. However, researchers face difficulties in developing more intensive models because Moore’s Law—which states that computational power doubles every two years—is slowing, and memory bandwidth still cannot keep up with it. But scientists can speed up simulations of complex systems by using compression algorithms running on AI hardware.
A team led by computer scientist Hatem Ltaief are tackling this problem head-on by employing hardware designed for artificial intelligence (AI) to help scientists make their code more efficient. In a paper published in the journal High Performance Computing, they now report making simulations up to 150 times faster in the diverse fields of climate modeling, astronomy, seismic imaging and wireless communications.
Previously, Ltaief and co-workers showed that many scientists were riding the wave of hardware development and “over-solving” their models, carrying out lots of unnecessary calculations.
Crops evolved

Comparing individual cells across corn, sorghum and millet reveals evolutionary differences among these important cereal crops, according to a new study led by New York University researchers.
The findings, published in Nature, bring researchers closer to pinpointing which genes control important agricultural traits such as drought tolerance, which will help scientists faced with a changing climate adapt crops to drier environments.
Corn, sorghum, and millet provide food for humans and animals around the world. Corn and sorghum are ancient relatives that evolved into two different species roughly 12 million years ago, and millet is a more distant relative.
TerraPower, founded by billionaire and Microsoft co-founder Bill Gates in 2008, is opening a new nuclear power plant in Kemmerer, Wyoming. The plant will be the first of its kind, with the company hoping to revolutionize the nuclear energy industry in the U.S. to help fight climate change and support American energy independence.
“Nuclear energy, if we do it right, will help us solve our climate goals,” Gates told ABC News. “That is, get rid of the greenhouse gas emissions without making the electricity system far more expensive or less reliable.”
Gates met with ABC News’ chief business, economics, and technology correspondent Rebecca Jarvis in Kemmerer to talk about the project.
This is really for the general public — and for people new to fusion. I gave a 20 minute talk** to a local group in Pittsburgh. We decided to record the audio, and put it out on the web for other people to enjoy. The top Ten things you should know about fusion are:
10. We have Been Doing It For Years.
9. We Know How To Make It Work.
8. You Can Do Fusion At Home.
7. The US Really Funded Fusion For about 15 year.
6. There Is More Than One Method.
5. Fusion Startups Are Real.
4. We Need A Pipeline.
3. China Is Taking An Interest.
2. Superconductors Are Game Changers.
1. Climate Change Is Not Waiting.
** Edits:
1. When I say 8, I meant 9
2. To clarify: ENN is investing ~10 million to built a duplicate of Dr. Cohens’ machine over in China. They’ve staffed up over there.
New insights into how X-ray flashes are produced during lightning strikes have been made by research.
Volcanoes are enigmatic and formidable forces of nature, with unbelievable power that can shatter the very foundation of the Earth.
These colossal mountains of molten rock and ash have the ability to unleash devastation on a scale that is beyond human comprehension. While most of us don’t have to see the deadly effects of volcanic eruptions everyday, it doesn’t mean that they don’t happen.
A lot of the time though, these eruptions are fairly small, but sometimes, they show their full force to make sure we know just how powerful they are… and well, NASA just announced a 50 mile eruption has cracked open the Earth, and it’s about to take everything down with it.
