Researchers breathe life into hopes for lab-grown lungs

Scientists in New York have successfully turned human stem cells into functional lung and airway cells for the first time. It’s a breakthrough the researchers at Columbia University believe could eventually lead to the creation of lab-made lungs, using a patient’s own cells. Sharon Reich reports.

Body parts on a chip

It’s relatively easy to imagine a new medicine, a better cure for some disease. The hard part, though, is testing it, and that can delay promising new cures for years. In this well-explained talk, Geraldine Hamilton shows how her lab creates organs and body parts on a chip, simple structures with all the pieces essential to testing new medications - even custom cures for one specific person.

Dark Matter Reveals the Structure of the Universe

We know that the dark matter has to be pretty cold - moving so slowly that its motion hardly matters - and that allows us to predict in great detail the large scale structure of the universe.

The World’s Biggest, Fastest, Priciest Private Jet

The Dubai Air Show has seen record orders for new planes. Bloomberg’s Elliott Gotkine got a look inside the show’s premier private jet: the Gulfstream G-650. It’s the biggest, fastest and most expensive worldwide.

Graphene’s potential to provide drinking water

Graphene is the ultrathin form of carbon that promises many exciting applications on account of its unique mechanical and electrical properties. 

This film takes you to the lab at the University of Manchester in the UK, where graphene was first discovered in 2004, to explore one of these potential applications: water purification. 

Scientists describe how graphene can be used as a selective filter that remove impurities from water, or even to produce drinking water from seawater through the process of desalination.

This film is one of a three-part series exploring some of the most promising technologies that are emerging from physics research. 

The Higgs Field, explained by Don Lincoln

One of the most significant scientific discoveries of the early 21st century is surely the Higgs boson, but the boson and the Higgs Field that allows for that magic particle are extremely difficult to grasp. Don Lincoln outlines an analogy (originally conceived by David Miller) that all of us can appreciate, starring a large dinner party, a raucous group of physicists, and Peter Higgs himself.

Four Real Inventions Inspired by Science Fiction

Where science fiction becomes science fact - that is the place Hank is exploring in today’s episode of SciShow. Many inventions we use today were first imagined in stories that described fantastical futures. Hank talks about the origins of four of these: the cell phone, the submarine, the telemanipulator (or robot arm), and the taser. Blast off for knowledge!

Tiny lab under the skin could stop drug cheats

Amid yet more claims of illegal drug-taking by high-profile athletes, scientists in Switzerland say they may have found a foolproof way to prevent the use of banned substances in sports. They say their chip implant, designed to monitor naturally-occurring substances in the blood, could also be used as a weapon against drug cheats.
