Proposals for beaming solar power down from space have been around since the 1970s, but the idea has long been seen as little more than science fiction. Now, though, Europe seems to be getting serious about making it a reality.

Space-based solar power (SBSP) involves building massive arrays of solar panels in orbit to collect sunlight and then beaming the collected energy back down to Earth via microwaves or high-powered lasers. The approach has several advantages over terrestrial solar power, including the absence of night and inclement weather and the lack of an atmosphere to attenuate the light from the sun.

But the engineering challenge involved in building such large structures in space, and the complexities of the technologies involved, have meant the idea has remained on the drawing board so far. The director general of the European Space Agency, Josef Aschbacher, wants to change that.

This week, scientists announced that the James Webb Space Telescope, which among its many talents can analyze the atmospheres of exoplanets, just confirmed the presence of carbon dioxide on a world orbiting a sun some 700 light-years away. It’s the first observation of CO₂ in a planetary atmosphere beyond our solar system.

But that discovery, made about a world very unlike our own, is just the first taste of what Webb’s instruments may soon reveal. Astronomers are eager to focus the telescope on planets like Earth, where liquid water, a crucial ingredient for life as we know it, is abundant. In the coming months and years, they will undoubtedly get their chance.

There are a number of promising Earth-like planets Webb could study in the near future, but in a paper published recently in The Astronomical Journal, scientists from the University of Montreal argue they’ve discovered one of the best such candidates yet.

As her new book on the origins of the universe is published, the Albanian-American scientist explains how her work on multiverse theory influenced Stephen Hawking.

The team even transmitted video games through the atoms to a monitor.

Scientists at the US National Institute of Standards have developed an ‘Atomic Television’ that uses lasers and atom clouds to pick up video transmissions that meet the 480i resolution standard. The team demonstrated the same by transmitting live video feeds and even video games through the atoms to a monitor.

This will be very useful in progressing the field of quantum computers and communication.

Researchers at the Max Planck Institute of Quantum Optics set a new record after achieving a quantum entanglement of 14 photons, the largest on record so far, an institutional press release said.

Quantum entanglement, famously described by Albery Einstein as “spooky action at a distance” is a phenomenon where particles become intertwined in such a way that they cease to exist individually, and changing the specific property of one results in an instant change of its partner, even if it is far away.

Sea Wave Energy Ltd (SWEL) has been working for more than a decade on a floating wave energy device it calls the Waveline Magnet. With several prototypes tested on-and off-shore, the company claims it delivers “ultra low cost,” with high output.

Solar electricity generation is proliferating globally and becoming a key pillar of the decarbonization era. Lunar energy is taking a lot longer; tidal and wave energy is tantalizingly easy to see; step into the surf in high wave conditions and it’s obvious there’s an enormous amount of power in the ocean, just waiting to be tapped. But it’s also an incredibly harsh and punishing environment, and we’re yet to see tidal or wave energy harnessed on a mass scale.

The dreams of our counterparts in parallel worlds.

Americans keep moving to where the water isn’t and where extreme weather is becoming the norm.

People are still flocking to Sunbelt regions where the housing is cheaper and plentiful — but climate change and extreme weather are worsening.

Summary: Researchers at the Human Brain Project have identified and mapped 7 new areas of the insular cortex.

All newly detected areas are now available as 3D probability maps in the Julich Brain Atlas, and can be openly accessed via the HBP’s EBRAINS infrastructure.
