Ultrathin ‘Invisibility Cloak’ Can Match Any Background

Posted by in category: materials

Invisibility cloaks are designed to bend light around an object, but materials that do this are typically hard to shape and only work from narrow angles — if you walk around the cloaked object, for instance, it’s visible. But a new cloak avoids that problem, and is thin and flexible enough to be wrapped around an object of any shape, the researchers said. It can also be “tuned” to match whatever background is behind it — or can even create illusions of what’s there, they added.

Led by Xiang Zhang, director of materials science at Lawrence Berkeley National Laboratory, the group constructed a thin film consisting of a 50-nanometer-thick layer of magnesium fluoride topped by a varying pattern of tiny, brick-shaped gold antennas, each 30 nanometers thick. (For comparison, an average strand of human hair is about 100,000 nanometers wide.) The “bricks” were built in six different sizes, ranging from about 30 to 220 nanometers long and 90 to 175 nanometers wide. [Now You See It: 6 Tales of Invisibility in Pop Culture]

The scientists then wrapped up a tiny, irregularly shaped object measuring about 36 microns across, or a bit more than one-thousandth of an inch. Shining a light, with a wavelength of 730 nanometers, or near-infrared, they found that it reflected back almost perfectly. The light scattering from the cloak still bounced off the object, but without revealing where the object was — as though there were just a flat mirror in its place, the researchers said.

What if U.S. had raised interest rates?

Posted by in categories: economics, finance, government, policy

At the end of 2015, the US national debt will be 18.6 trillion dollars. With such a big number, it’s tempting to put it in perspective by comparing it with things more easily envisioned. 98e2c31e5c194d21be9fd3922dc45fde9207f454Alas, I can not think of anything that puts such an oppressive and unfair burden into perspective, except to this:

US debt represents a personal obligation of $60,000 for each American citizen. And it is rising quickly. Most of our GDP is used simply to pay down interest on that debt. Few pundits see a way out of this hole.

bretton_woods-aIn my opinion, that hole was facilitated in August 1971, when the US modified the Bretton Woods Agreement and unilaterally terminated convertibility of the US dollar to gold. By forcibly swapping every dollar in every pocket and bank account with the promise of transient legislators, individual wealth was suddenly based on fiat instead of something tangible or intrinsic.

Hacking sleep: Meet the transhumanists making sleep obsolete

Posted by in categories: health, life extension, neuroscience, transhumanism

Not everyone wants to sleep in. A growing transhumanism community wants to sleep less, and better, and they’re going to great lengths to make it happen.

For those unaware, transhumanism is an intellectual and cultural movement that aims to improve the human condition, to push beyond our biological limitations, largely through technological advancements. They’re particularly focused on extreme longevity. But with treatments for an extended healthy life still works in progress (and playing out on a very long timeline), some transhumanists have turned their attention to sleep.

The average well-rested person sleeps eight hours a day. The average American lives 79 years. That’s a little more than just 50 years being awake. Life is much shorter than you realized — at least if you agree with your typical sleep-hacker that sleeping is wasted downtime.

The UK’s first self-driving ‘pod’ vehicle hits the streets

Posted by in categories: robotics/AI, transportation

The self-driving vehicle revolution has gotten underway in the UK, with the first of a number of automated ‘pod’ trial vehicles unveiled to the public in Milton Keynes this week.

The LUTZ (Low-carbon Urban Transport Zone) Pathfinder is a diminutive electric-powered two-seater that’s about half the length of an ordinary car. If you feel the need for speed, however, you may want to look elsewhere for now. The Pathfinder is designed for use in pedestrianised areas, with a top speed of just 24 km/hr.
