Since it started orbiting Saturn last June, the Cassini mission has returned incredible images of the gas giant, its dazzling rings and its enigmatic moons. But its most dramatic chapter will come this January, when a European lander probe (Huygens) that has been piggybacking on Cassini for the last seven years is sent on a fiery plunge into the murky atmosphere of Saturns largest and most mysterious moon, Titan--a chapter that would have ended in disaster, save for an engineer called Boris Smeds.
Titan is completely covered by a thick orange smog of hydrocarbons, and scientists have speculated that oily oceans of methane and ethane may roil beneath the cloaking clouds. After slamming into the moons atmosphere at 21,000 km/hour, Huygens will take two-and-a-half hours to descend through the atmosphere, slowed by parachutes. On its way down its expected to transmit a scientific bonanza from its cameras and instruments, a bonanza that will be picked up by special radio receivers onboard Cassini and then relayed back to Earth.
But unbeknownst to anyone, a lurking flaw in Cassinis receivers meant that the data received by Cassini were going to be hopelessly scrambled. Along with his allies, ESA engineer Boris Smeds developed and championed a rigorous test that revealed the flaw and its cause in time for corrective action to be taken. Doing this required Smeds to battle bureaucracy, travel from his desk in Darmstadt, Germany, to an antenna farm deep in Californias Mojave Desert, and use all his engineering insight and creativity to expose the flaw before time ran out.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
