Wouldn't it be nice if psychiatrists could stick patients with depression in an EEG and find out what antidepressant, like an SSRI, might be best for them, eliminating months of trial and error? A new study shows how that might be coming...

Optimal foraging theory means that turning down food is sometimes more efficient than eating it - but even then, what’s “wasted” doesn’t necessarily go to waste.

You don't need political power to make real change, says activist Katie Fahey. She tells the story of how she led a successful movement in Michigan to end gerrymandering — the practice of drawing district lines to favor one political...

Photosynthesis is one of the most important processes on the planet, helping produce the food we eat and the air we breathe. Crop scientist Steve Long thinks it could be more efficient — and he's intent on giving it a boost. He shows how...

We all want green energy to stop climate change, and one option is hydrogen. But achieving green hydrogen is tough, so some want to consider so-called blue hydrogen instead. Support for this video provided by Gates Ventures.<br/>

If there’s one thing cooler than a black hole it’s a rotating black hole. Why? Because we can use them as futuristic power generators, galactic-scale bombs, and portals to other universes.

Black holes are self-sustaining...

It’s fair to say that black holes may be the scariest objects in the universe. Happily for us, the nearest is probably many light-years away. Unless of course, Planck relics are a thing - in which case they might be literally everywhere.

Over 600 million years ago, sheets of ice coated our planet on both land and sea. How did this happen? And most importantly for us, why did the planet eventually thaw again? The evidence for Snowball Earth is written on every continent...

In 2003, microbiologists made a huge discovery. One that would force us to reconsider a lot of what we thought we knew about the evolution of microbial life: giant viruses.

A 9,500-year-old burial in Cyprus represents some of the oldest known evidence of human/cat companionships anywhere in the world. But when did this close relationship between humans and cats start? And how did humans help cats take over...

We tend to think that evolution only goes in one direction— toward getting bigger and more advanced. But that’s not always the case. This tiny, simple animal, the Myxozoans, (yes, animal!) evolved from something bigger and more complex.

When we scan the heavens with giant telescopes we see galactic cannibalism everywhere. We see moments that appear frozen on the human timescale, but are really snapshots of the incredibly violent process of galaxy formation. This is how...

Carl Sagan’s famous words: “We are star stuff” refers to a mind-blowing idea – that most atomic nuclei in our bodies were created in the nuclear furnace and the explosive deaths of stars that lived in the ancient universe. In recent...

In some places, the rocks below the Great Unconformity are about 1.2 billion years older than those above it. This missing chapter in Earth’s history might be linked to a fracturing supercontinent, out-of-control glaciers, and maybe the...

One day around 15,000 years ago, a wall of ice 2,000 feet tall and 30 miles wide suddenly broke wide open, and it unleashed the largest flood that we know of in the history of Earth. Come and hit the road with me as we search for the...

In 2003, Singapore's national water agency launched an unprecedented program to provide more than 50% of their nation's water supply by recycling wastewater. The program had been planned for decades to ensure the island nation never ran...

In a blistering talk, Nobel Laureate Al Gore looks at the two main obstacles to climate solutions and gives his view of how we might actually solve the environmental crisis in time. You won't want to miss his searing indictment of fossil...

From the astonishing evolutionary advances of the Cambrian explosion to our present-day computing revolution, the trend of dramatic growth after periods of stability can be explained through the theory of the "adjacent possible," says...

What happens when human and machine creativity meet? From an AI model trained on classic works to generate a seemingly infinite stream of portraits to a neural network that envisions otherworldly life-forms in impossible detail, media...

Supercritical water produces fire without flames, which is great for making clean drinking water from our waste in space or breaking down forever chemicals here on Earth.

When someone gets a PET scan to detect tumors and how far a cancer has spread, that machine is actually detecting sugar. Because cancer has a sweet tooth, and this phenomenon, called the Warburg effect, may help us develop new cancer...

For us terrestrial animals, sneezing is a regular part of life involving the movement of a lot of air. But animals that live underwater and don't breathe air like we do also sneeze. Sea sponges, corals, and hagfish use their snot to...

Join the Amoeba Sisters on this introduction to the human Skeletal System! This video first introduces several types of skeletal systems found in different organisms before focusing on the human endoskeleton. Then, this video takes a...

Ammonia is extremely useful to us as a crucial ingredient in fertilizers. But producing it also has a significant carbon footprint, which is why scientists have been on the hunt for a way to make ammonia production greener.
