Chemical engineers and biophysicists have successfully tracked single molecules inside living cells with carbon nanotubes. Through this new method, they found that cells stir their interiors using the same motor proteins that serve in muscle contraction.
Reid Reimers explains one of the often-overlooked technologies that humans need to live in, and explore, space: space suits. Learn about the hundred-year history of the pressurized suit, and see what the future of space couture might look like.
Inflatable Heat Shields Could Drop-Ship Bigger Robots
The Hypersonic Inflatable Aerodynamic Decelerator, or HIAD, is rigorously tested in NASA’s Armstrong Flight Research Center. This technology is being developed to deliver larger payloads to planets more efficiently.
A team of solar thermal engineers and scientists at our Energy Centre in Newcastle have used the ample sunlight flooding their solar fields to create what’s called ‘supercritical’ steam — an ultra-hot, ultra-pressurised steam that’s used to drive the world’s most advanced power plant turbines — at the highest levels of temperature and pressure EVER recorded with solar power.
A few centuries ago, the arbiter of “local noon” wasn’t the mechanical clock, it was the sundial. The pseudoscientific-sounding “equation of time” is how you convert between the two — and perhaps not the way you’d expect.
Who needs goal-line technology when you have physics? Watch as Andy explains how a little bit of physics could’ve proved that Lampard’s disallowed 2010 world cup goal went in.
In a crucial World Cup 2010 knock-out match, with the game in the balance, Frank Lampard scored a beautiful goal from outside the area. It thwacked the underside of the crossbar, bounced inside the goal, and then bounced back out.
But the celebrations were over before they had even begun. Neither the referee nor linesman thought the ball had crossed the line. No goal was given, play continued, and England ultimately crashed out of the competition.
Goal-line technology is the solution many called for, but perhaps there was a simpler option: teach referees a bit of physics. Here, Andy returns to the Ri Prep Room to use a simple demo to explain how the spin of the ball made it bounce out of the goal, and why the referees shouldn’t have needed any technology to know it was a goal.
Solar power is cheaper and more sustainable than our current coal-fueled power plants, so why haven’t we made the switch? The real culprits here are the clouds, which make solar power difficult to control. Alexandros George Charalambides explains how solar towers and panels create electricity and how scientists are trying to create a system that can function even under cloud cover.
In science fiction films like Men in Black and Total Recall, characters can have their memories wiped clean with a push of a button. But that’s just sci-fi, right? Wrong!
Memories aren’t just intangible - they’re physical connections in our brains. And now scientists are developing procedures that could allow us to do some amazing things with memory. In the future it might be possible to erase bad memories, and return good memories to people who have lost them!
