Moss-growing concrete absorbs CO2, insulates and is also a vertical garden

Posted by in categories: biological, climatology, sustainability

Buildings with this concrete can—in regions with a calm mediterranean climate—absorb CO2 and release oxygen with micro-algae and the other “pigmented microorganisms” that coat it. These vertical gardens boast aesthetic appeal, but the biological concrete’s beauty also lies in its clever design.

The concrete works in layers. The top layer absorbs and stores rainwater and grows the microorganisms underneath. A final layer of the concrete repels water to keep the internal structure safe. The top can also absorb solar radiation, which insulates the building and regulates temperatures for the people inside.

5 Big Ideas for Making Fusion Power a Reality

Posted by in categories: humor, nuclear energy, particle physics

After decades of not happening, fusion power finally appears to be maybe possibly happening.


The joke has been around almost as long as the dream: Nuclear fusion energy is 30 years away…and always will be. But now, more than 80 years after Australian physicist Mark Oliphant first observed deuterium atoms fusing and releasing dollops of energy, it may finally be time to update the punch line.

Over the past several years, more than two dozen research groups—impressively staffed and well-funded startups, university programs, and corporate projects—have achieved eye-opening advances in controlled nuclear fusion. They’re building fusion reactors based on radically different designs that challenge the two mainstream approaches, which use either a huge, doughnut-shaped magnetic vessel called a tokamak or enormously powerful lasers.

New Theory Could Solve Universe’s Biggest Paradox

Posted by in categories: cosmology, physics

She is now hopeful that advances in gravitational wave astronomy will make it possible to test the predictions of massive gravity theory within the decade.

“It would be amazing if it was shown to be right,” De Rham told The Guardian. “That may or may not happen, but what will happen is that we’ll have a much better fundamental understanding of gravity and that’s just something so deep, it’s one of the big questions today.”

The U.S. Marines Plan to Use Powerful Robots to Move Around Equipment and Weapons

Posted by in categories: military, robotics/AI

Key point: Washington knows it needs high-tech weapons and machines to win future wars. That includes robots to haul supplies and assist the Marines in winning any fight.

The U.S. Navy is moving quickly to develop robotic warships that could hunt submarines and other ships, screen aircraft carriers and convoys from air attack and sweep away enemy mines.

But there’s another mission the Navy should consider assigning to unmanned surface vessels, Neil Zerbe, a retired Navy officer, argued for the Center for International Maritime Security: shuttling supplies from ship to shore in the aftermath of an amphibious assault by U.S. Marines.

How to Levitate Objects With Sound (and Break Your Mind)

Posted by in categories: chemistry, robotics/AI

Along with personal jetpacks for every man, woman, and child (sure, why not), levitation is one of those conveniences that sci-fi has long promised us but has yet to deliver, other than magnetically levitating trains. But at Argonne National Laboratory in Illinois, physicist Chris Benmore and his colleagues are levitating objects with an unlikely tool: sound. It’s called acoustic levitation, and after breaking your brain with what seems to be an optical illusion, it’s poised to deliver advances in pharmacology, chemistry more broadly, and even robotics.

The Pacific Ocean is so acidic that it’s dissolving Dungeness crabs’ shells

Posted by in categories: biotech/medical, economics, habitats

The Pacific Ocean is becoming more acidic, and the cash-crabs that live in its coastal waters are some of its first inhabitants to feel its effects.

The Dungeness crab is vital to commercial fisheries in the Pacific Northwest, but lower pH levels in its habitat are dissolving parts of its shell and damaging its sensory organs, a new study found.

Their injuries could impact coastal economies and forebode the obstacles in a changing sea. And while the results aren’t unexpected, the study’s authors said the damage to the crabs is premature: The acidity wasn’t predicted to damage the crabs this quickly.
