Whether it’s turning forests into cropland or savannah into pastures, humanity has repurposed land over the last 60 years equivalent in area to Africa and Europe combined, researchers said Tuesday.

If you count all such transitions since 1960, it adds up to about 43 million square kilometres (16.5 square miles), four times more than previous estimates, according to a study in Nature Communications.

“Since land use plays a central role for climate mitigation, biodiversity and food production, understanding its full dynamics is essential for sustainable land use strategies,” lead author Karina Winkler, a physical geographer at Wageningen University & Research in the Netherlands, told AFP.

Children are our future, in every sense of the word. But what might that future be like, and how might it shape the lives of young people? Thanks to COVID and numerous other social, ecological, and technological shifts taking place right now, the future of childhood is evolving.

So what happens when three leading female futurists come together to envision what the children of the future could be like or what world they might inhabit? The result is this article, that shares creative and thought-provoking profiles of five kids from the future.

Toyota’s first car in its new Beyond Zero brand will be the bZ4X electric SUV. Look for it before the end of 2022.

Car companies love to create new brands. The Japanese Big Three gave us Lexus, Infiniti, and Acura 30+ years ago when they wanted to go upmarket with high profit premium cars. People who would never consider dropping $30000 on a Toyota were happy to spend double that on a Lexus. Such is the power of branding.

In the electric car era, several companies have have created new brands for their battery powered cars. Mercedes has its EQ division, Volkswagen its ID branded cars, BMW uses a simple “i,” while Hyundai is employing the Ioniq moniker for its battery electric cars. While all those companies have been ramping up EV offerings, Toyota has been largely content to hang out in the background and sell variations of its Synergy hybrid powertrain, cars it often misleadingly characterizes as “self charging electric cars.”

Pretty soon, you’ll start seeing this term on very expensive items.

New Material Absorbs and Stores Solar Energy ‘The light that is thus trapped can be released by making a small spark near the glass.’ — L. Sprague de Camp, 1940.

3D Printed Damascus Steel Now Possible ‘… lined with durite, that strange close-packed laboratory product.’ — Robert Heinlein, 1939.

Engineers at Duke University have developed the world’s first fully recyclable printed electronics. Their recycling process recovers nearly 100% of the materials used—and preserves most of their performance capabilities for reuse.

By demonstrating a crucial and relatively complex computer component—the transistor—created with three carbon-based inks, the researchers hope to inspire a new generation of recyclable electronics.

“Silicon-based computer components are probably never going away, and we don’t expect easily recyclable electronics like ours to replace the technology and devices that are already widely used,” said Aaron Franklin, the Addy Professor of Electrical and Computer Engineering at Duke. “But we hope that by creating new, fully recyclable, easily printed electronics and showing what they can do, that they might become widely used in future applications.”

EcoTech Recycling’s patented thermodynamic process turns waste rubber into a nontoxic synthetic material for new tires, auto parts and insulation.

If you’ve ever seen a tire graveyard piled high with trashed rubber, you can easily understand that Israeli company EcoTech Recycling has a green gem of an idea.

EcoTech’s nontoxic process produces a unique material, Active Rubber (AR), from end-of-life tires. With1.6 billion tires manufactured annually, and 290 million tires discarded each year in the United States alone, tires are the world’s largest source of waste rubber.

“Rubber is a valuable commodity, and we are making it reusable,” says CEO and President Gideon Drori.

Have you seen those plant trees instead of go to space memes recently? Well, aside from believing we can do both, I wanted to remind people what great things we use everyday due to the technological developments that the space race has spawned. Not least, the monitoring of illegal deforestation, but right through to better baby food, cleaner water and incredible digital cameras!! But that is not all, so here is my Top 10 technologies, that we have the space industry to thank for…

We have everything we need here Especially in Texas no one ever needs to freeze again if they come out of the Fossil Fuel stone age.

The idea is that when electric vehicles are not in use, the energy stored in their batteries is going to waste. If you make it possible for that energy to feed back into the grid, then it can help balance out dips in supply as renewables go offline, rather than relying on fossil-fuel plants to pick up the slack.

The technology that can make that happen is still in its infancy, though. When an electric vehicle is charged, the alternating current from the grid is converted to direct current that can be stored in its batteries. But most charging stations and cars don’t have the hardware to allow this process to run in reverse, meaning the power can’t be fed back into the grid.

That’s starting to change, though, and a city in the Netherlands is leading the charge. In the last two years Utrecht has installed nearly 500 bi-directional charging stations and is positioning itself as one of the world’s leading test beds for the technology.

For the first time, a spacecraft on another planet has recorded the sounds of a separate spacecraft. NASA’s Perseverance Mars rover used one of its two microphones to listen as the Ingenuity helicopter flew for the fourth time on April 30, 2021. A new video combines footage of the solar-powered helicopter taken by Perseverance’s Mastcam-Z imager with audio from a microphone belonging to the rover’s SuperCam laser instrument.

The laser zaps rocks from a distance, studying their vapor with a spectrometer to reveal their chemical composition. The instrument’s records the sounds of those laser strikes, which provide information on the physical properties of the targets, such as their relative hardness. The microphone can also record , like the Martian wind.

With Perseverance parked 262 feet (80 meters) from the helicopter’s takeoff and landing spot, the rover mission wasn’t sure if the microphone would pick up any sound of the flight. Even during flight, when the helicopter’s blades spin at 2537 rpm, the sound is greatly muffled by the thin Martian atmosphere. It is further obscured by Martian wind gusts during the initial moments of the flight. Listen closely, though, and the helicopter’s hum can be heard faintly above the sound of those winds.
