If we’re serious about feeding the world’s growing population healthy food, and not ruining the planet, we need to get used to a new style of eating. This includes cutting our Western meat and sugar intakes by around 50%, and doubling the amount of nuts, fruits, vegetables and legumes we consume.
Titan’s Thick Clouds Obscure our View, but Cassini Took these Images in Infrared, Showing the Moon’s Surface Features
Saturn’s moon Titan is a very strange place. It’s surrounded by a dense, opaque atmosphere, the only moon in the solar system with an atmosphere to speak of. It has lakes of liquid methane on its surface, maybe some cryovolcanoes, and some scientists speculate that it could support a form of life. Very weird life.

A New Technique to Figure Out How Old Stars Are
Our understanding of the universe, and of the Milky Way, is built on an edifice of individual pieces of knowledge, all related to each other. But each of those pieces is only so accurate. The more accurate we can make one of the pieces of knowledge, the more accurate our understanding of the whole thing is.

Bizarre Double Star System Flipped its Planetary Disk on its Side
Astronomers theorize that when our Sun was still young, it was surrounded by a disc of dust and gas from which the planets eventually formed. It is further theorized that the majority of stars in our Universe are initially surrounded in this way by a “protoplanetary disk“, and that in roughly 30% of cases, these disks will go on to become a planet or system of planets.

Hubble sees the brightest quasar in the early Universe
The NASA/ESA Hubble Space Telescope has discovered the brightest quasar ever seen in the early Universe. After 20 years of searching, astronomers have identified the ancient quasar with the help of strong gravitational lensing. This unique object provides an insight into the birth of galaxies when the Universe was less than a billion years old.
Physicists have managed to measure the 'weak force' inside atoms for the first time ever
Quantum computer: we’re planning to create one that acts like a brain
The human brain has amazing capabilities making it in many ways more powerful than the world’s most advanced computers. So it’s not surprising that engineers have long been trying to copy it. Today, artificial neural networks inspired by the structure of the brain are used to tackle some of the most difficult problems in artificial intelligence (AI). But this approach typically involves building software so information is processed in a similar way to the brain, rather than creating hardware that mimics neurons.

Our obsession with taking photos is changing how we remember the past
I recently visited the Hermitage in St Petersburg, Russia – one of the best art museums in the world. I was expecting to serenely experience its masterpieces, but my view was blocked by a wall of smart phones taking pictures of the paintings. And where I could find a bit of empty space, there were people taking selfies to create lasting memories of their visit.
In the far Future our Sun will Turn Into a Solid Crystalline White Dwarf. Here’s How it’ll Happen
About fifty years ago, astronomers predicted what the ultimate fate of our Sun will be. According to the theory, the Sun will exhaust its hydrogen fuel billions of years from now and expand to become a Red Giant, followed by it shedding it’s outer layers and becoming a white dwarf. After a few more billion years of cooling, the interior will crystallize and become solid.

It Looks Like Dark Matter Can be Heated Up and Moved Around
Look at a galaxy, what do you see? Probably lots of stars. Nebulae too. And that’s probably it. A whole bunch of stars and gas in a variety of colorful assortments; a delight to the eye. And buried among those stars, if you looked carefully enough, you might find planets, black holes, white dwarves, asteroids, and all sorts of assorted chunky odds and ends. The usual galactic milieu.

‘The Cow’ explosion: how astronomers are cracking one of the greatest new mysteries of the sky
Something highly unusual was picked up by the Asteroid Terrestrial Impact Last Alert System (ATLAS) on June 16, 2018. The discovery of a strange flare in the sky – brightening and fading – was reported in an astronomical telegram, which then alerted scientists. The source was named AT2018cow – based on a naming convention for transient sources where the last three letters are randomly assigned. Understandably, though, scientists quickly nicknamed it “the Cow”.
