Scientists in Israel unveiled a 3D print of a heart with human tissue and vessels on 15.04.2019, calling it a first and a “major medical breakthrough” that advances possibilities for transplants. While it remains a far way off, scientists hope one day to be able to produce hearts suitable for transplant into humans as well … Read more
Since November 2, 2000, the International Space Station has been continuously crewed meaning humanity has had a permanent presence in space. This importance of this station cannot be overstated—NASA has literally filled a book with all the ways the ISS has benefited humans on earth. It’s helped develop new cancer treatments, enhanced robotic surgery technology, improved data processing techniques, its … Read more

There is no doubt about it that sharks are awesome. And they can do some pretty incredible things. … Read more
Graphene is a two-dimensional atomic-scale material, that is made of a single layer of carbon atoms that have a high level of cohesion through hybridisation bonds sp2 and arranged in a uniform surface, slightly undulating, with a similar appearance to a honeycomb lattice because of its hexagonal configuration. Graphene is an allotropic form of carbon, … Read more
An utterly, wonderous achievement. Astronomers using the Event Horizon Telescope have taken the first ever photograph of a black hole. Here’s the story, about a hundred years ago, Albert Einstein gave us a new description of the force of gravity in which gravity exerts its influence through warps and curves in the fabric of space … Read more

Batteries are necessities of modern life, powering everything from cell phones to vehicles. Most batteries operate via chemical reactions that convert stored chemical energy into electrical energy. These electrochemical reactions are triggered when a load (e.g. a light bulb) is connected to a battery, causing electrons to flow. Though traditional batteries are ubiquitous and can … Read more
Power is the one thing a spacecraft can’t work without. Without the technology to reliably power, no long term space missions would be possible, thus our knowledge of the solar system would be only a fraction of what it is today. It might sound surprising, but there are currently only two practical options for providing … Read more
Lettuce, peas and radishes are just a few vegetables that are found in a summer garden. But did you know these same vegetables also can be grown in space? Crew members aboard the International Space Station have been growing such plants and vegetables for years in their “space garden.” A space station study is helping … Read more
The Earth intercepts a lot of solar power: 173 thousand terawatts. That’s ten thousand times more power than the planet’s population uses. So is it possible that one day the world could be completely reliant on solar energy? To answer that question, we first need to examine how solar panels convert solar energy to electrical … Read more
