One Of The Most Unexplored Areas On Earth Looks Stunning From Space

“So much water in this New Guinea rainforest, I’ve never seen anything like this!” tweeted NASA Astronaut Terry W. Virts. Indeed, those countless rivers reflecting the sun looks unbelievably beautiful and mysterious at the same time in this image.

This Is What A Blood Clot Looks Like Close-Up

This image looks like it could the a colourful underwater coral reef or a child’s breakfast cereal strewn across the floor. But it is, in fact, what a blood clot looks like if you zoom right in.

Why Do Radio Signals Travel Farther At Night Than In The Day?

Not all radio waves travel farther at night than during the day, but some, short and medium wave, which AM radio signals fall under, definitely can given the right conditions. The main reason this is the case has to do with the signal interacting with a particular layer of the atmosphere known as the ionosphere, and how this interaction changes from the nighttime to the daytime.

How Radical 1970s Scientists Tried To Change The World

In the 1970s, radical scientists thought they could change the world — if they could change science first. As told to Alice Bell.

High-Speed Cameras Reveal Why Sodium Explodes In Water

You remember the sodium demo from chemistry class: Just a small chunk of the pure metal dropped into water causes a great big flash and bang. You might even remember your chemistry teacher’s explanation for why. But there’s always been a missing piece of the puzzle, which scientists have finally figured out using high-speed video cameras.

Which Religions Are Prepared To Accept Life In Space?

Assuming we don’t blow ourselves up before then, colonising other planets may be the last hope for the survival of humanity. Most of the preparation for this cosmic expansion has centred around solving the more immediate, physical problems of transporting our bodies into deep space, but what about our culture? Therein lies an issue that’s often overlooked: Can the major monotheistic religions of the world reconcile what space means for our immortal souls?

Batteries Made With Bulletproof Kevlar Fibres May Never Explode

One of the most common reasons that batteries explode and catch fire — like on Boeing’s 787 Dreamliner — is because over time small conductive pathways grow inside the battery’s inner structure that eventually cause it to short out with disastrous results. But Nicholas Kotov, a professor at the University of Michigan, and Siu On Tung, a PhD student, may have come up with a solution to the problem using bulletproof kevlar nanofibres.

Watch This Reflected Laser Pulse's Entire Flight Path At 20 Billion FPS

The technology available to image light as it moves through space continues to advance. Recently, we saw a new high-speed camera capture a small pulse reflected from a mirror; now, it’s possible to image the entire flight path of a laser as it bounces around a laboratory.

This Star Model Is Based On Nothing But Shadows

Saturn’s rings are already mind-blowingly large — about 70,000km across — but astronomers at the Leiden Observatory in the Netherlands have found a much more extensive ring system. At least they think they have — all they can actually see are shadows.

A Floating Artificial Reef Would Let You Walk Down Into The Ocean Deep

This month, a grim study in the journal Science reported what we’ve feared for decades: That the ocean may “be sitting on a precipice of a major extinction event,” in the words of one author. There’s a colossal amount of work to be done if we want to turn it around — including reclaiming habitats, which is the goal of this ambitious proposal by three young architects.
