Meet "Hedgehog": Your tour guide to asteroids, comets and other things that whirl around the solar system
A team of engineers builds a cube-like rover for exploration in some of the most extreme conditions in space.
Your best guess is that the landscape is as inhospitable as it gets: an irregular range of sharp boulders and loose rubble piles strewn among jagged crevasses and deep troughs of dust. But then again, it’s just a guess because no one’s ever actually seen this landscape up close. Now imagine that you need to send a robot across that landscape, from a perch at the lip of a steep crater to the edge of an ice-encrusted hole 1,000 meters away. And imagine that gravity is a tiny fraction of what we have on Earth.

A new study shows how harnessing the quantum properties of light can create a transmission technology impervious to eavesdropping.
Imagine communicating with your bank, the IRS or your doctor by way of an Internet that was perfectly secure. Your most private data would be protected with absolute certainty and, better yet, if any bad actor were to try to eavesdrop you would know immediately. Such is the promise of secure quantum communication.

Hailed for the discovery of superplastic steel, Sherby was a professor at Stanford for 30 years. He was known on campus for his affable manner and for organizing volleyball matches and poker games.
Oleg Dimitri Sherby, a professor emeritus at Stanford best known for his discovery of superplastic steel, died Nov. 9 at his home in Menlo Park. He was 90 years old.

Stanford researchers have invented a lithium-ion battery that turns on and off depending on the temperature. The new technology could prevent battery fires that have plagued laptops, hoverboards and other electronic devices.
Stanford researchers have developed the first lithium-ion battery that shuts down before overheating, then restarts immediately when the temperature cools.

Lasers are nothing like meteor strikes, but in the nanosecond when each strike silicon dioxide, the main ingredient in coastal sand, stishovites form. Understanding how this rare crystal form will help improve laser technology and allow Earth scientists to better understand meteor impacts.
An asteroid smashing into the earth and a laser pulsing through optical glass are very different phenomena, but both produce the extreme heat and pressures that instantaneously fuse silicon dioxide – the compound found in sand and glass -- into the hard, dense and rare crystal known as stishovite.
Named after Sergey M. Stishov, the Russian physicist who first synthesized it in 1961, stishovite means different things to different scientists.
To geologists, stishovite provides residual proof of a meteor impact.

Stanford engineers have discovered how to make the electrical wiring on top of solar cells nearly invisible to incoming light. The new design, which uses silicon nanopillars to hide the wires, could dramatically boost solar-cell efficiency.
A solar cell is basically a semiconductor, which converts sunlight into electricity, sandwiched between metal contacts that carry the electrical current.
But this widely used design has a flaw: The critical but shiny metal on top of the cell reflects sunlight away from the semiconductor where electricity is produced, reducing the cell's efficiency.
