How Will Humans Colonize Space in the Years Ahead?

Exploration is one of humanity’s greatest drivers. We’ve moved around the planet and into almost every environment—mountains, deserts, jungles, and swamps. But will we be able to take the next step and adapt ourselves to...

Dark Matter Makes Up a Quarter of the Universe, But What Is It?

Until the 1960s, scientists thought ordinary matter and radiation made up everything in the universe. Then a young physicist named Vera Rubin made a discovery that shook things up. Rubin uncovered an unexpected relationship...

How Is Technology Evolving Over Time?

What was humanity’s first invention? Some say it was the wheel, while others say it was fire. But perhaps it was our invention of communication. Without this, no tool can be conceptualized, built, replicated,...

Einstein Was a Genius, But Was He Always Right?

Einstein was a genius, there’s no debating that. He was a Nobel Prize-winner who changed our understanding of nature more than anyone since Newton. Einstein is famous for his theory of relativity, his pioneering work...

The Search to Find Another Earth Like Ours Is Heating Up

Are there other planets out there like our own? If so, could other forms of life, intelligence, or civilizations inhabit them? This age-old question is a key part of the study of exoplanetology, the scientific...

Should We Edit Human Genes? What You Need to Know

There’s a difference between editing genes in a person’s somatic cells and germline cells. Editing somatic cells, which are differentiated (e.g., skin cells) and non-reproductive, impacts them alone. In contrast, editing germline DNA means changes...

Here Are 3 Good Reasons Why It’s Time to Return to the Moon

Since 1962 when President John F. Kennedy declared, “We choose to go to the moon in this decade,”moon exploration has sparked the imagination. Today, Peter Diamandis says, moon exploration is as exciting as Alaska...

Now That Anyone Can Hack Biology—Should We Be Afraid?

Biohacking is a relatively new field of amateur and professional scientists conducting “do-it-yourself” biology experiments. The word “hacking”may bring up images of cybercrime, but the majority of biohacking projects are focused on helping society as...

This Is What Happens to Your Body in Space

Living in space sounds pretty cool. Unfortunately, our bodies haven’t evolved to live in space without suffering harm. You may wonder, “How bad could it really be?” In space, changes in gravity cause blood to...

Why Quantum Computers Will Be Exponentially Faster Than Digital Computers

Classical computers (like the one you may be reading this on) calculate using bits, or binary digits, which can have only one of two values, either 1 or 0. Quantum computers, however, calculate using...

Do We Have the Right to Edit the Genes of an Entire Species?

Scientists can now more cheaply and efficiently edit animal and human DNA using the CRISPR/Cas9 gene editing system. But should we edit species, and if so, to what extent? An interesting way to consider this question...

When Will We Have the Technology to Reach the Stars?

Recent advances in rocket technology are incredible. From NASA’s Space Launch System to Blue Origin and SpaceX’s reusable rockets, space is getting more accessible.  However, no rocket can get us to neighboring stars. The...
