‘Tornado of Fire’ Is Latest Sight on the Sun’s Tumultuous Surface

The sun is moving into the hyperactive phase of its roughly 11-year cycle when sunspots, solar flares and all other sorts of tumultuous heliocentric happenings become more common. Case in point: A vortex of fire as tall as 10 Earths stacked on top of each other could be seen doing a quick dance on the sun’s surface late Tuesday.

NASA’s Solar Dynamics Observatory caught an eruption from the sun that swirled like a tornado as it produced a bright coronal mass ejection, or CME. Astronomer Tony Phillips clipped the below footage for Spaceweather.com.

CMEs are blasts of charged plasma that often accompany solar flares. When they’re directed at Earth, they can produce bright auroras when they collide with our magnetosphere. This particular CME that started with the rare solar twister was not directed at Earth.

Recycled glass waste used as sand replacement in 3D printing

Researchers from Nanyang Technological University, Singapore (NTU Singapore) have developed the capability to use recycled glass in 3D printing, opening doors to a more environmentally sustainable way of building and construction.

Glass is one material that can be 100% recycled with no reduction in quality, yet it is one of the least recycled waste types. Glass is made up of silicon dioxide, or silica, which is a major component of sand, and therefore it offers significant untapped potential to be recycled into other products.

At the same time, due to growing populations, urbanization and , the world is facing a shortage of sand, with calling it one of the greatest sustainability challenges of the 21st century.

Why Venus Rotates, Slowly, Despite Sun’s Powerful Gravitational Pull

Gaining clarity about the factors that contributed to a runaway greenhouse state on Venus, Earth’s closest planetary neighbor, can also help improve models of what could one day happen to Earth’s climate.

“Ultimately, my motivation in studying Venus is to better understand the Earth,” Kane said.

Survey: Trust in science is high, but misinformation is a threat

Trust in science is rising worldwide, according to a 3M-backed survey released Tuesday, and more people expect it to solve the world’s problems.

But the fifth annual 3M State of Science Index also showed many are worried that misinformation could lead to more , greater societal divisions and lack of action on climate change.

“It’s really good to see that trust in is high, and that’s true in America and around the world, but misinformation threatens scientific credibility,” Jayshree Seth, 3M’s corporate scientist and chief science advocate, said in an interview. “It’s not simply a matter of communicating facts, data and evidence. We need to build that relationship with the public.”

Meteorologists get key upgrade just in time for 2022 hurricane season

The official start of Atlantic Hurricane Season is less than six weeks away, and forecasters will be getting an essential upgrade just in time for the season to begin.

New technology from the University of Wisconsin will help with preparation of more detailed forecasts and provide more reliable information to meteorologists and emergency planners, which should ultimately result in better, safer outcomes for public safety.

The Advanced Dvorak Technique (ADT) is a satellite-based method for determining tropical cyclone intensity. Planned upgrades include the use of full-resolution images from weather satellites, better identification of the location of each storm’s eye and the ability to better analyze hurricanes occurring outside tropical regions.

Will Rising Gas Prices Speed Up the Transition To A Zero-Emission Future?

Please welcome a second posting here at 21st Century Tech Blog, from Katie Brenneman. Katie’s previous contribution looked at how individuals can practice sustainability to mitigate the threat of climate change. Her many interests include writing on lifestyle, mental health, and sustainability. You can follow her on Twitter.

In this contribution, Katie has chosen a timely topic: the increasing consumer interest in electric vehicles (EVs). The recent stratospheric rise in gasoline and diesel prices because of Russia’s invasion of Ukraine has made EVs far more attractive. That plus more announcements about new EV models, i.e., The Ford Lightning (an EV version of the F-150) may prove to be the moment when North Americans begin a rapid move away from fossil-fuel-powered vehicles?

As fuel prices continue to rise around the world, many consumers are taking another look at EVs as a potential solution for their transportation needs. This follows historical trends that show whenever there is a spike in gas and diesel costs it is accompanied by an increase in EV sales. Online searches for EVs continue to double with many in the renewable energy sector wondering if this is the watershed moment that will finally move us to take zero-emission actions seriously.

An architect designs semi-floating buildings that can help cool the planet

Architect Andreas Tjeldflaat from design and research studio, Framlab, has his head high up in the clouds.

His latest project, titled Oversky, was recently on display at an exhibition on architecture and climate change at Sweden’s Bildmuseet art museum.

Oversky deals with a series of semi-floating structures in the ariel space between roads and buildings. The modular structures would be based on the technology that allows zeppelins to float, known as the lighter-than-air technology, and would be interconnected and supported by various infrastructural links that connect the street, known as “the cloudscape”.
