We can reprogram life. How to do it wisely

April 25, 2016

For four billion years, what lived and died on Earth depended on two principles: natural selection and random mutation. Then humans came along and changed everything — hybridizing plants, breeding animals, altering the environment and even purposefully evolving ourselves.

Is radiation dangerous?

March 16, 2016

When we hear the word radiation, it’s tempting to picture huge explosions and frightening mutations. But that’s not the full story — radiation also applies to rainbows and a doctor examining an X-ray. So what is it, really, and how much should we worry about its effects?

The Problem With Invisibility Is The Blindness

March 12, 2016

Invisibility is one of those science fiction superpowers, along with flight or super speed, that almost everyone has at least dreamt of having. In our current age, with the emerging science of metamaterials, invisibility seems closer than ever to becoming a reality. But there is still one problem: if a person achieved true, perfect invisibility, they would probably be blind!

In terms of invisibility our best hope yet of one day disappearing entirely is by bending light around us.

To get light to bend around a space or object and seamlessly come back together on the other end is no easy feat. But even if we could do it, there’s another problem. You’d be invisible to others, sure, but you couldn’t see anything.

Since your vision is based on the light rays that enters your eyes, if all of these rays were diverted around someone under an invisibility cloak, the effect would be like being covered in a thick blanket. Total darkness. Learn more here.

The Chemistry of Lighting a Match

February 27, 2016

The process takes merely tenths of a second. But within that tiny amount of time, there’s a lot going on. The American Chemical Society used a high-speed camera operating a 4,000 frames a second to illustrate the sequence of chemical reactions that take place when a match is struck against a striker. The simple match is a marvelously complex device.

Scientists Find Evidence for Ninth Planet in Solar System

January 21, 2016

Is there anybody out there? Two astronomers say they have found evidence that a planet around 10 times the mass of Earth is lurking in the outer reaches of the solar system, on an orbit that comes no closer than 200 times the distance between the sun and Earth. Dubbed Planet Nine, it hasn’t been seen directly. Instead scientists of the California Institute of Technology in Pasadena have inferred its existence from the strange orbits of other, smaller bodies.
