US paralympic athletic champion Lex Gillette holds the long jump world record. But while his athletic abilities put him at the top of his sport, he often struggles with common tasks most people take for granted. Gillette has been blind since age 8, and navigating a grocery store would be "one of those things where a lot of times the stores will have a customer service area, so I would go to that desk that would require me to have a specific list of items," he says. "There are those times...

The devastating effects of climate change are everywhere. Now, the fight to save the planet is taking an innovative turn. What if scientists could offset dangerous greenhouse gas levels by capturing CO2 from the atmosphere and putting it to use? This episode looks at two project that aim to capture CO2 and convert it into useable products. The first would combine basalt and CO2. Basalt is naturally highly reactive with CO2; when the two meet, they undergo a series of exchanges that culminate...

The vaquita is the world’s smallest cetacean, a miniature porpoise with what some describe as cartoonlike features, and dark smudges around its eyes. The marine mammal lives only in the fertile waters of the Mexico’s Gulf of California. The problem: it shares its habitat with the totoaba, a fish coveted by wealthy Chinese who believe it has mystical medicinal powers. The vaquita are trapped in illegal gillnets set for the totoaba. In this episode, TechKnow looks at the various efforts to...

In this episode of TechKnow, we look into the science of immunotherapy, which involves tricking the body’s immune system into attacking cancerous tumours. Donated T-cells are given an extra gene to make them target specific leukemia cells along with other genes which are disabled to stop them attacking their host. We also explore a promising cancer drug called Pembrolizumab. This drug make the tumour visible to the T-cells. More from TechKnow on: Twitter - https://Twitter.com/AJTechKnow...
