In this week's SciShow News, we discuss two new types of sensors being developed. One tracks the content of certain molecules in your sweat while you exercise and the other is a brain implant that can be resorbed once it has finished its...

What's cooler: A vaccine for one of the deadliest bacterial infections around or a holodeck? Well, this week we got a step closer to BOTH!

There's no better way to stop a disease than to catch and treat it early, before symptoms occur. That's the whole point of medical screening techniques like radiography, MRIs and blood tests. But there's one medium with overlooked...

Scientists have been trying to pull blood out of the body and put it back in again since the early 1800s, but bypass machines haven't been easy to get right.

Researcher Kwabena Boahen is looking for ways to mimic the brain's supercomputing powers in silicon -- because the messy, redundant processes inside our heads actually make for a small, light, superfast computer.

Showing a series of inspiring, unusual and playful products, British branding and design guru Paul Bennett explains that design doesn't have to be about grand gestures, but can solve small, universal and overlooked problems.

Hank talks with University of Montana Professor Rick Hughes about innovating technology and training the SciShow staff. Special guest appearance with Jessi and Veiled Chameleon 'Twirly'.

Daniel Kraft demos his Marrow Miner -- a new device that quickly harvests life-saving bone marrow with minimal pain to the donor. He emphasizes that the adult stem cells found in bone marrow can be used to treat many terminal conditions,...

You probably know the common symptoms of a heart attack: chest and arm pain, shortness of breath and fatigue. But there's another kind that's just as deadly and harder to detect because the symptoms are silent. In this quick talk,...

At the intersection of medical invention and indigenous culture, pediatric cardiologist Franz Freudenthal mends holes in the hearts of children across the world, using a device born from traditional Bolivian loom weaving. "The most...

At TED@Cannes, Gary Wolf gives a 5-min intro to an intriguing new pastime: using mobile apps and always-on gadgets to track and analyze your body, mood, diet, spending -- just about everything in daily life you can measure -- in...

Timothy Prestero thought he'd designed the perfect incubator for newborns in the developing world -- he even won awards for it. But he and his team learned a hard lesson when their incubator completely failed to catch on. Hear his...

Another Host vs Host edition of the SciShow Quiz Show!

Tan Le's astonishing new computer interface reads its user's brainwaves, making it possible to control virtual objects, and even physical electronics, with mere thoughts (and a little concentration). She demos the headset, and talks...

We check our phones upwards of 50 times per day -- but when our kids play around with them, we get nervous. Are screens ruining childhood? Not according to children's media expert Sara DeWitt. In a talk that may make you feel a bit less...

Rather than demo another new technology, Tom Wujec reaches back to one of our earliest but most ingenious devices -- the astrolabe. With thousands of uses, from telling time to mapping the night sky, this old tech reminds us that the...

How comfortable are you with robots taking over your life? Covering a wide range of potential applications -- from the mundane (robot house cleaner) to the mischievous (robot sex partner) to the downright macabre (uploading your brain to...

Many of us have longed for cool sci-fi inventions like a holodeck or replicators, but there's one tool we're actually getting pretty darn close to creating: the medical tricorder.

Our emotions influence every aspect of our lives -- how we learn, how we communicate, how we make decisions. Yet they're absent from our digital lives; the devices and apps we interact with have no way of knowing how we feel....

What's the science behind a sublime perfume? With charm and precision, biophysicist Luca Turin explains the molecular makeup -- and the art -- of a scent.

This demo -- from Pattie Maes' lab at MIT, spearheaded by Pranav Mistry -- was the buzz of TED. It's a wearable device with a projector that paves the way for profound interaction with our environment. Imagine "Minority Report" and then...

What if you could control digital devices using just the power of thought? That's the incredible promise behind the Stentrode -- an implantable brain-computer interface that collects and wirelessly transmits information directly from the...

What will the world look like when we move beyond the keyboard and mouse? Interaction designer Sean Follmer is building a future with machines that bring information to life under your fingers as you work with it. In this talk, check out...

Hank talks about how warp drives could potentially work.
