Schemas for the Real World
Social app development challenges us to code for users’ personal world. Users are giving push-back to ill-fitted assumptions about their own identity - name, gender, sexual orientation, important relationships, and many other attributes that are individually meaningful.

Seeing Theory - A visual introduction to probability and statistics
Seeing Theory is a project designed and created by Daniel Kunin with support from Brown University's Royce Fellowship Program. The goal of the project is to make statistics more accessible to a wider range of students through interactive visualizations. Seeing Theory visualizes the fundamental concepts covered in an introductory college statistics or Advanced Placement statistics class. Students are encouraged to use Seeing Theory as an additional resource to their textbook, professor and peers.

Cassini Finds Saturn Moon May Have Tipped Over
Whether it was caused by an impact or some other process, Tajeddine and colleagues think the disruption and creation of the tiger-stripe terrain caused some of Enceladus' mass to be redistributed, making the moon's rotation unsteady and wobbly. The rotation would have eventually stabilized, likely taking more than a million years. By the time the rotation settled down, the north-south axis would have reoriented to pass through different points on the surface -- a mechanism researchers call "true polar wander."

A Whole New Jupiter: First Science Results from NASA’s Juno Mission
“Every 53 days, we go screaming by Jupiter, get doused by a fire hose of Jovian science, and there is always something new,” said Bolton. “On our next flyby on July 11, we will fly directly over one of the most iconic features in the entire solar system -- one that every school kid knows -- Jupiter’s Great Red Spot. If anybody is going to get to the bottom of what is going on below those mammoth swirling crimson cloud tops, it’s Juno and her cloud-piercing science instruments.”

These scientists made 2,879 tiny clay caterpillars and hid them all over the world
The fake caterpillars revealed that, indeed, predation is highest near the equator and lowest near the poles; for every 1 degree of latitude north or south of the equator, the odds of a caterpillar getting attacked decreased by 2.7 percent. So a caterpillar in Zackenberg, Greenland was about 87 percent less likely to get bitten than a caterpillar at the equator.

Open-Plan Offices Kill Productivity
Enclosed private offices clearly outperformed open-plan layouts in most aspects of IEQ (Indoor Environmental Quality), particularly in acoustics, privacy and the proxemics issues. Benefits of enhanced 'ease of interaction' were smaller than the penalties of increased noise level and decreased privacy resulting from open-plan office configuration.

Time lapse of a cloud inversion filling the Grand Canyon with an undulating vaporous ocean
Usually, the air nearest the Earth is the warmest and it gets cooler as the altitude increases. But sometimes, there’s a meteorological inversion and colder air gets trapped near the ground with a layer of warmer air on top. While working on a dark sky project, Harun Mehmedinovic shot a time lapse movie of a rare cloud inversion in the Grand Canyon, in which the entire canyon is filled nearly to the brim with fluffy clouds.

Using Wi-Fi to Get 3D Images of Surrounding Location
The radio signals emitted by a commercial Wi-Fi router can act as a kind of radar, providing images of the transmitter’s environment, according to new experiments. Two researchers in Germany borrowed techniques from the field of holography to demonstrate Wi-Fi imaging. They found that the technique could potentially allow users to peer through walls and could provide images 10 times per second.

The Amazing Dinosaur Found (Accidentally) by Miners in Canada
At first glance the reassembled gray blocks look like a nine-foot-long sculpture of a dinosaur. A bony mosaic of armor coats its neck and back, and gray circles outline individual scales. Its neck gracefully curves to the left, as if reaching toward some tasty plant. But this is no lifelike sculpture. It’s an actual dinosaur, petrified from the snout to the hips.

Can Programming Be Liberated from the von Neumann Style? — John Backus
There are numerous indications that the applicative style of programming can become more powerful than the von Neumann style. Therefore it is important for programmers to develop a new class of history-sensitive models of computing systems that embody such a style and avoid the inherent efficiency problems that seem to attach to lambda-calculus based systems.

Although retractions are on average occurring sooner after publication than in the past, citation analysis shows that they are not being recognised by subsequent users of the work.

More aggressive means of notification to the scientific community appear to be necessary.

The results highlight a stark contrast along lines of violence, forgiveness, and power.
