4 Fun Facts Animated By Teachers

British astronaut Tim Peake made this timelapse of lightning storms from the International Space Station. He says it was recorded as he flew from North Africa over Turkey towards Russia.

The simple discovery that a piece of wire mesh can stop a flame in its tracks saved the lives of thousands of miners.

This demonstration shows how a simple lamp made of gauze could contain the open candle flames that miners used before 1815. With the safety lamp, any potential explosions would stay contained and never escalate to dangerous levels (although mining remained an extremely dangerous occupation).

Physicists Predict The Existence of New Particle in the “Material Universe”

Scientists are predicting the existence of the type-II Weyl fermion. This comes after they realized that a metallic crystal material, called tungsten ditelluride, was exhibiting a strange behavior. While most metals turn into insulators once subjected to a magnetic field, tungsten ditelluride becomes either an insulator or a conductor, which one it becomes ultimately depends on the direction of the subjected magnetic field.

After a team investigated the phenomenon, they predicted the presence of an unexpected particle—the previously mentioned type-II Weyl fermion—which caused the behavior.

Neurologists have found a scientific explanation for your lack of motivation

If you often struggle to get yourself motivated - or you have friends who seem stuck in a permanent state of apathy - new research might help to explain your slacker tendencies. Scientists have discovered a collection of inefficient connections in certain parts of the brain, and these weak links could be making things more difficult for some of us to rouse ourselves into action...

It’s not (completely) your fault. -ScienceAlert

There’s finally a Tesla that’s priced like a normal car

One thing we’re always doing as a species is expanding our knowledge of the heavens. We send out probes, robots, satellites, spacecraft, all to map out and add to our ever-expanding picture of what the Universe looks like.

But what if that picture suddenly became smaller? That is exactly what happened when new data from the Planck satellite tightened our previous notions of the observable universe, shrinking its area by 0.7%.

If you’ve never realized, we don’t actually see all of the stars in the Universe. If we did, night time sky would be a whole lot brighter. Instead, we see everything within a particular radius, the particle horizon. Any particle of light emitted outside that particle horizon is too far to have reached us.

So if we want to know just how large the observable universe is, we just have to figure out the distance between us and that particle horizon, right?

As it turns out, not quite.

The universe, specifically spacetime, is continuously expanding, with points in the universe moving further apart. This not only changes the distance between objects but also how fast light is moving in the universe. 

The movement of spacetime has an effect on which photons reach us and can be observed.

So how do you calculate the radius? Back in 2003, scientists came up with an equation that took an event called “the recombination” as a reference point in the universe’s history. They combined that with the rate of the expansion of the universe and several other factors, in the end coming up with a number.

Back in 2003, that number was a radius of 45.66 billion light-years. Now, new data revealed a far more accurate number: 45.34 billion light-years.

“A difference of 320 million light-years might be peanuts on the cosmic scale, but it does make our knowable universe a little bit cozier,” Nick Tomasello from the University of the Sciences in Philadelphia writes over at Medium.

The study has been accepted for publication in an upcoming edition of Advances in Astrophysics.

Scientists Make New Form of Gold That’s Nearly as Light as Air

Researchers in Switzerland have been able to produce gold foam that is almost as light as air. In fact, 98% of it consists of air; the rest is made up of 20-carat gold and milk protein. According to materials scientist Raffaele Mezzenga from ETH Zurich, this gold aerogel is a thousand times lighter than any other gold alloy, is lighter than water, and is almost as light as air itself.

Disabled violinist uses thoughts to make music for the first time in 27 years

This is incredible.

Rosemary Johnson was a promising violinist and member of the Welsh National Opera Orchestra when she was involved in a devastating car crash 27 years ago. The accident left her in a coma for seven months, and the resulting brain damage has robbed her of most of her ability to talk and move.

But thanks to new software that reads people’s brain waves, Johnson has been able to compose music for the first time since 1988, and has had the chance to have it played to her in real time by a professional string quartet.

“It was really very moving,” Eduardo Miranda from the Interdisciplinary Centre for Computer Music Research at Plymouth University in the UK, told The Telegraph.

Solar System: 2015 Year in Review

Two mysterious worlds explored for the first time. Liquid water seen flowing on Mars. A global ocean discovered hiding inside a moon of Saturn. Even during our Era of audacious solar system exploration, 2015 stands out. Here are a few highlights:

1. New Horizons Reveals the Face of Pluto

Whether or not you call it a planet, Pluto entranced the people of Earth when it sent a love note from three billion miles away via our New Horizons spacecraft.

2. Dawn Comes to Ceres

The dwarf planet Ceres, the largest object in the main asteroid belt, teased explorers with its bizarre bright spots before finally giving up some of its secrets to the Dawn spacecraft. HERE are the latest findings.

3. Cassini Marks Discoveries and Milestones at Enceladus

When the Cassini spacecraft performs its final close flyby of Saturn’s icy moon Enceladus on Dec. 19, it will be a true milestone. Scientists using data from Cassini’s instruments have uncovered astounding secrets about this small moon, including (confirmed this year) the fact that its underground ocean of liquid water is global, and is home to hydrothermal vents.

4. We Confirmed Evidence that Liquid Water Flows on Today’s Mars

Findings from our Mars Reconnaissance Orbiter (MRO) provided the strongest evidence yet that liquid water flows intermittently — on present-day Mars.

5. Rosetta Passes Perihelion

The European Space Agency’s Rosetta mission had a remarkable year, re-establishing contact with the Philae lander and following comet 67P/Churyumov-Gerasimenko as it swung near the sun.

6. Mars Explorers Confirm Lakes Once Dotted Mars

A study from the team behind our Mars Science Laboratory/Curiosity Rover confirmed that Mars was once, billions of years ago, capable of storing water in lakes over an extended period of time.

7. MAVEN Finds a Culprit in the Loss of Mars’ Atmosphere

The Mars Atmosphere and Volatile Evolution (MAVEN) mission identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported surface life to the cold, arid planet that Mars is today.

8. Akatsuki Gets a Second Chance at Venus

Five years after a mishap sent the spacecraft off course, the Japan Aerospace Exploration Agency (JAXA) successfully inserted the Venus Climate Orbiter “Akatsuki” into orbit around Venus. While the mission is not funded by NASA, an agency partnership with JAXA provides an opportunity for eight of our scientists to work with the Akatsuki team and study data from the spacecraft over the next year or so.

9. A Trailblazing Mission Sends Its Final Message from Mercury

After a flight of nearly 11 years, the highly successful MESSENGER mission ended when, as planned, the spacecraft slammed into the surface of Mercury.

10. Mars Reconnaissance Orbiter Completes 40,000 Orbits

Mars Reconnaissance Orbiter, at Mars since 2006, has orbited the Red Planet more than 40,000 times. The mission, which studies the whole planet from space, has shown that Mars is diverse and dynamic by way of many thousands of spectacular images and other kinds of data.

The plate is called a Chladni plate. When he plays it with a bow (you know, like a violin) the couscous aligns itself it certain patterns. We’re not sure if this is science or magic.
