When a new pathogen emerges, our bodies and healthcare systems are left vulnerable. And when this pathogen causes the outbreak of a pandemic, there’s an urgent need for a vaccine to create widespread immunity with minimal loss of life....

Alternative energy is great, but our infrastructure isn't exactly equipped to handle it. So scientists are coming up with other ways to use it, including turning it into food.

How can we transplant animal tissue into humans? And will we ever be able to grow customized organs? SciShow explains!

Flatulence is a daily phenomenon. In fact, most human beings pass gas 10-20 times a day (yes, that includes you). Where does your bodily gas come from? Purna Kashyap takes us on a journey into the intestines, shedding light on how gas is...

Physicist Brian Greene explains superstring theory, the idea that minscule strands of energy vibrating in 11 dimensions create every particle and force in the universe.

Given the option, few would choose to buy products that harm the earth -- yet it's nearly impossible to know how most consumer goods are made or where they're sourced from. That's about to change, says supply chain innovator Markus Mutz....
