Brilliant iron molecule could provide cheaper solar energy

Posted by in categories: solar power, sustainability

For the first time, researchers have succeeded in creating an iron molecule that can function both as a photocatalyst to produce fuel and in solar cells to produce electricity. The results indicate that the iron molecule could replace the more expensive and rarer metals used today.

Some photocatalysts and are based on a technology that involves containing metals, known as . The task of the complexes in this context is to absorb solar rays and utilise their energy. The metals in these molecules pose a major problem, however, as they are rare and expensive metals, such as the noble metals ruthenium, osmium and iridium.

“Our results now show that by using advanced molecule design, it is possible to replace the rare metals with iron, which is common in the Earth’s crust and therefore cheap,” says Chemistry Professor Kenneth Wärnmark of Lund University in Sweden.

Syfy’s Nightflyers asks whether humanity deserves to be saved

Posted by in categories: bioengineering, genetics, neuroscience, space travel

Showrunner Jeff Buhler has built a fascinating world around Martin’s story seeds, starting by setting the action within the foreseeable future, rather than in an incomprehensibly distant one. The invented technologies here are particularly intriguing, like the genetic modifications first officer Melantha Jhirl (Jodie Turner-Smith) has to make her better suited for space travel, or the cybernetics technician Lommie (Maya Eshet) uses to interface with machinery. Given the state of real-world technological developments in genetic engineering and research into brain-machine interfaces, the series feels plausible and grounded, even though it’s set in a spacefaring future.


The 10-episode space series adapts a 40-year-old George R.R. Martin novella.

NASA opens $2.6 billion in contract services for Moon to Mars missions

Posted by in categories: policy, space travel

“We are going,” is an important part NASA’s motto for its return to the Moon, and to get there, the space agency will need corporate partners. As part of carrying out the private sector integration requirements of White House Space Policy Directive 1, NASA Administrator Jim Bridenstine announced today at 2 pm EST the nine companies the agency has selected to compete for $2.6 billion in contracts to support its Moon to Mars mission. These contracts will be geared to filling the needs of NASA’s Commercial Lunar Payload Services Program over the next ten years of its development.

Machine learning, meet quantum computing

Posted by in categories: military, quantum physics, robotics/AI

Back in 1958, in the earliest days of the computing revolution, the US Office of Naval Research organized a press conference to unveil a device invented by a psychologist named Frank Rosenblatt at the Cornell Aeronautical Laboratory. Rosenblatt called his device a perceptron, and the New York Times reported that it was “the embryo of an electronic computer that [the Navy] expects will be able to walk, talk, see, write, reproduce itself, and be conscious of its existence.”

MIT Studies Micro-Impacts at 100 Million Frames Per Second

Posted by in categories: particle physics, space travel

Engineers know that tiny, super-fast objects can cause damage to spacecraft, but it’s been difficult to understand exactly how the damage happens because the moment of impact is incredibly brief. A new study from MIT seeks to reveal the processes at work that produce microscopic craters and holes in materials. The hope is that by understanding how the impacts work, we might be able to more durable materials.

Accidental space impacts aren’t the only place these mechanisms come into play. There are also industrial applications on Earth like applying coatings, strengthening metallic surfaces, and cutting materials. A better understanding of micro-impacts could also make these processes more efficient. Observing such impacts was not easy, though.

For the experiments, the MIT team used tin particles about 10 micrometers in diameter accelerated to 1 kilometer per second. They used a laser system to launch the projectile that instantly evaporates a surface material and ejects the particles, ensuring consistent timing. That’s important because the high-speed camera pointed at the test surface (also tin) needed specific lighting conditions. At the appointed time, a second laser illuminated the particle allowing the camera to follow the impact at up to 100 million frames per second.
