Could we clone humans? - Earth Lab

Adults Biology
Dom Burgess investigates whether we could clone humans in the future.

How does your immune system work? - Emma Bryce

Adults Biology
The immune system is a vast network of cells, tissues, and organs that coordinate your body's defenses against any threats to your health. Without it, you'd be exposed to billions of bacteria, viruses, and toxins that could make something as minor as a paper cut or a seasonal cold fatal. So how does it work? Emma Bryce takes you inside the body to find out.

What are mini brains? - Madeline Lancaster

Adults Biology
Shielded by our thick skulls and swaddled in layers of protective tissue, the human brain is extremely difficult to observe in action. Luckily, scientists can use brain organoids - pencil eraser-sized masses of cells that function like human brains but aren't part of an organism - to look closer. How do they do it? And is it ethical? Madeline Lancaster shares how to make a brain in a lab.

All the nasty things inside a pimple

What is in a pimple?

How do fish make electricity? - Eleanor Nelsen

Adults Biology
Nearly 350 species of fish have specialized anatomical structures that generate and detect electrical signals. Underwater, where light is scarce, electrical signals offer ways to communicate, navigate, find, and sometimes stun prey. But how do these fish produce electricity? And why? Eleanor Nelsen illuminates the science behind electric fish.

How Close Are We to Curing HIV/AIDS?

Adults Biology
Current drug therapies mean it's possible to live a normal life span with HIV, but that's expensive and not a long term solution. What we really need is an HIV vaccine and a cure. So, how close are we?

Why Are You Anxious?

Adults Biology
When you're feeling or stressed, your body releases stress hormones, such as adrenaline and cortisol...

Your Face Could Be Recreated From DNA: Should You Worry?

Adults Biology
Can we predict what a person's face looks like based solely on a sample of their DNA? A new study says yes, but geneticists aren't so sure.

Why is it so hard to cure cancer? - Kyuson Yun

Adults Biology
We've harnessed electricity, sequenced the human genome, and eradicated smallpox. But after billions of dollars in research, we haven't found a solution for a disease that affects more than 14 million people and their families at any given time. Why is it so difficult to cure cancer? Kyuson Yun explains the challenges.

One Shot Could Provide All the Vaccines You'll Ever Need

Adults Biology
Hate needles? Researchers may have found a way to combine all the vaccines you'll ever need into a single shot. Here's how it works.

5 useless human body parts left over from evolution

Adults Biology
Your body is walking proof of evolution, but some parts have grown unnecessary over time. Here are five useless body parts left over from evolution.

Do You Really Have Two Brains?

Adults Biology
Are you a left-brained person or a right-brained person? Spoiler: You're neither. Each of us uses both sides of our brain for most of what we do. But still, there are a number of brain functions that do show lateralization, where they are localized to one side or another. Why is this? And how does it influence our definition of consciousness? People with "split brains" can help us figure it out.

DNA Doesn't Look Like What You Think!

Adults Biology
Biology textbooks are full of drawings of DNA, but none of those show what DNA actually looks like. Sure, they're good models for understanding how DNA works, but inside of real cells, it's a whole lot more interesting. Learn why we can't look directly at DNA, and find out how DNA is actually packed inside cells.

What makes muscles grow? - Jeffrey Siegel

Adults Biology
We have over 600 muscles in our bodies that help bind us together, hold us up, and help us move. Your muscles also need your constant attention, because the way you treat them on a daily basis determines whether they will wither or grow. Jeffrey Siegel illustrates how a good mix of sleep, nutrition and exercise keep your muscles as big and strong as possible.

Lab-Grown Mosquitoes Are Being Released by the Millions, Here's What You Need to Know

Adults Biology
Mosquitoes kill more people annually than any other animal on earth. But several research companies are looking to tame this issue.

Your Body Is Designed to Attack a New Organ, Now We Know Why

Adults Biology
Scientists think they've found the molecular basis for organ transplant rejection. Now that we know its cause, could we prevent its effect?

Revolutionizing Heart Surgery With Virtual Reality

Adults Biology
Have you ever wondered what it would be like to take a ride through the human body on the Magic School Bus? Well, a new bit of virtual reality technology is taking that concept and applying it to medical training. Doctors can now teleport inside the human heart and practice surgery over and over again, and this training could revolutionize the future of health care.

How Bilingual Brains Perceive Time Differently

Adults Biology
A new study has found that what language you speak might alter your perception of time.

Oxygen's surprisingly complex journey through your body - Enda Butler

Adults Biology
Oxygen forms about 21% of the air around us. In your body, oxygen forms a vital role in the production of energy in most cells. But if gases can only efficiently diffuse across tiny distances, how does oxygen reach the cells deep inside your body? Enda Butler tracks the surprisingly complex journey of oxygen through your body.

Why You're Attracted To Certain People

Adults Biology
Love is a beautiful thing, but what causes it? Well, it might all just be in your head.

The Unexpected Things Winter Does To Your Body

Adults Biology
Everyone suffers a little in the winter, be it human or animal, but how does cold climate actually change your body?
