Dark matter's most famous trait is its inability to interact with light, the particle version of which we call "photons". But in their attempts to figure out exactly what dark matter is, some scientists have proposed "dark photons".

There's a really interesting idea in anthropology called the grandmother hypothesis, that basically says the reason we have grandmas has to do with what makes us unique as a species. But there's a huge problem with the idea that it's...

On the Internet, koalas get an unnecessary amount of hate, so let's debunk some of the most pervasive koala myths!

The world has plenty of clean energy. The problem is storing that energy and getting it where we need it, when we need it, says battery recycling pioneer Emma Nehrenheim. While batteries are fundamental to powering a sustainable future,...

The vast, white surface of Antarctica stretches for over 3 million square kilometers. On the coast of this expanse, just a few meters beneath the ice, lies a remarkably diverse realm that is home to over 8,000 species of sea denizens who...

The metaverse could be our key to making real progress in the fight against climate change, says engineer Cedrik Neike. Examining how AI-powered modeling eliminates the trial and error of wasteful industries, he explores how this...

In the US, people spend the overwhelming majority of their time inside buildings that burn fossil fuels, which are bad for both the environment and human health. (Think: breathing in air pollution from gas stoves, furnaces and water...

We can produce abundant, sustainable and cheap energy — for everyone, says physicist Julio Friedmann. He explores the infrastructure, innovation and investment needed to supply energy to 10 billion people, offering case studies from...

AI won't kill us all — but that doesn't make it trustworthy. Instead of getting distracted by future existential risks, AI ethics researcher Sasha Luccioni thinks we need to focus on the technology's current negative impacts, like...

Everything our bodies do— whether physical or mental— uses energy. Studies have found that many individuals seem to have a daily threshold for making decisions, and an extended period of decision-making can lead to cognitive exhaustion....
