Gaps in coverage leave interceptors less-equipped to defeat the threats of tomorrow.

No missile defense is better than the sensors that tell the interceptors where to go and what to kill. The Ground-based Midcourse Defense system, or GMD, draws upon considerably more sensors for homeland defense than when operations began in 2004, but shortfalls remain. The North Korean and other missile threats are not diminishing, and it’s time to get this right.

In a forthcoming report, we recommend that the Defense Department and Missile Defense Agency take several steps to improve the sensor backbone of America’s homeland missile defenses, including fielding a space layer, filling radar gaps, adding omnidirectional focus, and improving command and control. Unfortunately, the budget for missile defense sensors has fallen considerably over the past decade, exactly the wrong trend for our changing security environment.

Researchers at the University of Cambridge, working with colleagues in Italy and China, have incorporated washable, stretchable, and breathable integrated electronic circuits into fabric for the first time — opening up new possibilities for smart textiles and wearable textile electronic devices.

The circuits were made with cheap, safe, and environmentally friendly inks, and printed using conventional inkjet-printing techniques.

As luck would have it, we may be on the verge of another revolution in miniaturization, this time through nanoelectronics.

Creating electronics at the nanoscale is difficult and has faced limitations but those limitations may be a thing of the past. Researchers from the National University of Singapore have developed a “converter” for nanoelectronic devices that could allow them to use plasmons for data processing.

A demonstration of the pressure sensor built by bacteria in action as a researcher taps out some Morse code.

As wonderfully bizarre as it sounds, growing touch screens from a bacterial soup isn’t the team’s ultimate goal.

Every modern economy wants its own version of Silicon Valley and in Japan the urge to find or create one is just as strong. Although the country’s pedigree as an innovator is not in doubt, rapidly adapting to the digital age has proven challenging for its once-mighty consumer electronics companies.

Fukuoka, Kyoto and Tokyo’s Shibuya district are all staking their claim.

A UK supermarket has become the first in the world to let shoppers pay for groceries using just the veins in their fingertips.

Customers at the Costcutter store, at Brunel University in London, can now pay using their unique vein pattern to identify themselves.

The firm behind the technology, Sthaler, has said it is in “serious talks” with other major UK supermarkets to adopt hi-tech finger vein scanners at pay points across thousands of stores.

A Sandia National Laboratories-led team has for the first time used optics rather than electronics to switch a nanometer-thick thin film device from completely dark to completely transparent, or light, at a speed of trillionths of a second.

The team led by principal investigator Igal Brener published a Nature Photonics paper this spring with collaborators at North Carolina State University. The paper describes work on optical information processing, such as switching or light polarization control using light as the control beam, at terahertz speeds, a rate much faster than what is achievable today by electronic means, and a smaller overall device size than other all-optical switching technologies.

Electrons spinning around inside devices like those used in telecommunications equipment have a speed limit due to a slow charging rate and poor heat dissipation, so if significantly faster operation is the goal, electrons might have to give way to photons.
