Big-brained scientists have found the mechanism that may have allowed their brains (and all humans') to get so big.

Paul Andersen describes how cell communication is used in both single-celled and multicellular organisms. He starts by describing the symbiotic relationship between the bobtail squid and the bacteria Vibrio fisheri. He explains how...

The simplest organisms can still accomplish wonders.

One team of researchers may has found a promising lead in the fight to cure or prevent Alzheimer's. And another team is helping us understand how Hydras regrow their heads.

Cambridge researcher Aubrey de Grey argues that aging is merely a disease -- and a curable one at that. Humans age in seven basic ways, he says, all of which can be averted.

Every summer it seems like there’s that one person who always gets a lot of mosquito bites. But what makes people mosquito magnets?

We talk a lot about CRISPR and "designer babies" but the science of editing genes is varied and complex. This month, an adult man received billions of gene-editing viruses via an IV in an effort to treat a rare disease.

They call you the human cannonball. Your act involves flying through rings of fire, bouncing through a trampoline course, and catching the trapezist in the grand finale. Today's pre-flight test fails dramatically, and upon inspection,...

Pioneering surgeon Susan Lim performed the first liver transplant in Asia. But a moral concern with transplants (where do donor livers come from ...) led her to look further, and to ask: Could we be transplanting cells, not whole organs?...

Your cells are coated with sugars that store information and speak a secret language. What are they trying to tell us? Your blood type, for one -- and, potentially, that you have cancer. Chemical biologist Carolyn Bertozzi researches how...

Anglerfishes are pretty unique creatures, but what’s really unique is how some of these species mate.

SciShow News shares the latest science headlines, including a newly-found butterfly that’s half male and half female, and new insights into the association between cancer and … breathing.

What if diseases could be treated with a patient's own cells, precisely and on demand? Biotech entrepreneur Nabiha Saklayen explains how we could harness advances in biology, machine learning and lasers to create personalized stem cell...

In August 2015, Jimmy Carter announced that he had a form of cancer that spread to his liver and brain. A few months later he reported the cancer was gone. How?

What color is your blood. Red, right? Well, actually, yes. So why does it look blue when you see it through your skin? And is everyone's blood always the same color red (spoiler: no)? Do all animals have red blood ('nother spoiler: no!)?...

Today, the organ transplantation is one of the well-known medical treatment, but the road to the first successful organ transplant was full of challenges, discoveries, and a whole lot of work.

There's another theory about the Covid-19 pandemic going around, and while it is pretty cool, it's not exactly the solution some are suggesting it might be.
