Every asteroid discovered since 1980 — animated timeline
From I Heart Chaos:
View of the solar system showing the locations of all asteroids starting in 1980. As asteroids are discovered they are added to the map and highlighted white so you can pick out the new ones. The final color of an asteroid indicates how close it comes to the inner solar system.
• Earth orbit crossers are red
• Earth orbit approachers (perihelion less than 1.3AU) are yellow
• All others are green
Notice now the pattern of discovery follows the Earth around its orbit, such that most discoveries are made in the region directly opposite the Sun. You’ll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons.
As the video moves into the mid 1990s we see much higher discovery rates as automated sky scanning systems come online. Most of the surveys are imaging the sky directly opposite the sun and you’ll see a region of high discovery rates aligned in this manner.
At the beginning of 2010 a new discovery pattern becomes evident, with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer), which is a space mission tasked with imaging the entire sky in infrared wavelengths.
PadFoot iPad Stand
From the website:
Designer Michiel Cornelissen wrote, "There are many stands for iPads on the market, but I couldn't find one that had the simplicity I was looking for. So, I ended up designing my own....."
From the website:
PadFoot is a stand for the iPad, designed to match the iPad's simplicity and elegance.
Great for viewing photos and clips in the upright position.
Slide PadFoot under your iPad for an improved typing and interaction angle.
Can be used in both portrait and landscape postion, allowing iPad to be charged in either orientation.
Made from lightweight, tough 3D printed polyamide with a fine surface texture.
Weighs under 15 grams (about 0.5 oz.).
Tales of Things
From the website : "Wouldn't it be great to link any object directly to a 'video memory' or an article of text describing its history or background? Tales of Things allows just that with a quick and easy way to link any media to any object via small printable tags known as QR codes."
Above, the first trailer from the TOTeM team.

You scratch off the places you've been with a coin.
"Top layer is gold foil for easy scratching."
Arrives rolled in a protective tube.
83 x 59cm (33" x 23").
Scientists create "dry water"
Here's the Telegraphs's August 26, 2010 story.
Scientists create "dry water"
It may sound like a contradiction in terms, but scientists have created "dry water."
The substance resembles powdered sugar and could revolutionise the way chemicals are used.
Each particle of dry water contains a water droplet surrounded by a sandy silica coating. In fact, 95 per cent of dry water is ''wet'' water.
Scientists believe dry water could be used to combat global warming by soaking up and trapping the greenhouse gas carbon dioxide.
Tests show that it is more than three times better at absorbing carbon dioxide than ordinary water.
Dry water may also prove useful for storing methane and expanding the energy source potential of the natural gas.
Dr Ben Carter, from the University of Liverpool, presented his research on dry water at the 240th National Meeting of the American Chemical Society in Boston.
He said: ''There's nothing else quite like it. Hopefully, we may see dry water making waves in the future.''
Another application demonstrated by Dr Carter's team was using dry water as a catalyst to speed up reactions between hydrogen and maleic acid.
This produces succinic acid, a key raw material widely used to make drugs, food ingredients, and consumer products.
Usually hydrogen and maleic acid have to be stirred together to make succinic acid. But this is not necessary when using dry water particles containing maleic acid, making the process greener and more energy efficient.
''If you can remove the need to stir your reactions, then potentially you're making considerable energy savings,'' said Dr Carter.
The technology could be adapted to create ''dry'' powder emulsions, mixtures of two or more unblendable liquids such as oil and water, the researchers believe.
Dry emulsions could make it safer and easier to store and transport potentially harmful liquids.
