Air Waveguides Use Differences in Density to Keep Light Beams Focused

23rd July 2014

Read it.

Scientists say they have turned thin air into an “optical fibre” that can transmit and amplify light signals without the need for any cables.

In a proof-of-principle experiment they created an “air waveguide” that could one day be used as an instantaneous optical fibre to any point on earth, or even into space.

The findings, reported in the journal Optica, have applications in long range laser communications, high-resolution topographic mapping, air pollution and climate change research, and could also be used by the military to make laser weapons.

Making the Cut

23rd July 2014

Read it.

Diode lasers — used in laser pointers, barcode scanners, DVD players, and other low-power applications — are perhaps the most efficient, compact, and low-cost lasers available.

Attempts have been made over the years to amplify the brightness of these valuable lasers for industrial applications, such as welding and cutting metal. But boosting power usually means decreasing beam quality, or focus. And the beam never gets intense enough to melt metal.

Now MIT Lincoln Laboratory spinout TeraDiode is commercializing a multikilowatt diode laser system that’s bright enough to cut and weld — even through a half-inch of steel — at greater efficiencies than today’s industrial lasers.

New Spongelike Structure Converts Solar Energy Into Steam.

21st July 2014

Read it.

The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure that floats on water. When sunlight hits the structure’s surface, it creates a hotspot in the graphite, drawing water up through the material’s pores, where it evaporates as steam. The brighter the light, the more steam is generated.

The new material is able to convert 85 percent of incoming solar energy into steam — a significant improvement over recent approaches to solar-powered steam generation. What’s more, the setup loses very little heat in the process, and can produce steam at relatively low solar intensity. This would mean that, if scaled up, the setup would likely not require complex, costly systems to highly concentrate sunlight.

From Alzheimer’s to ADHD: What Doctors Can Diagnose From Your Voice Alone

20th July 2014

Read it.

If Guillermo Cecchi wants to figure out if you’ve taken MDMA or meth, all he needs is a computer and a recording of your voice. Cecchi is a computer scientist at IBM, and part of a growing community of scientists who think our voices can reveal far more than our sex, age, or cultural origins. He thinks it can also unlock the mind — and the various psychological and neurological states our brains may be experiencing at any given time.

“This is exactly what psychiatrists do every day: they talk to the patients,” Cecchi says, “but we used machine learning and mathematics to replicate it.”

Pretty creepy.

The Viking Facebook

15th July 2014

Read it.

An unusual article recently appeared in the magazine of the Royal Statistical Society and American Statistical Association.

It featured web-like diagrams of lines connecting nodes, a hallmark of research that analyzes networks. But each node, rather than being a plain dot, was the head of a burly, red-bearded Viking sporting a horned hat, his tresses blowing in the wind.

This whimsical-seeming piece of scholarship went on to describe the social network of more than 1,500 characters in the Icelandic Sagas, epic tales about the colonization of Iceland around a thousand years ago that were first written down a few hundred years after that. It was the work of a pair of statistical physicists, Ralph Kenna of University of Coventry in the UK and his graduate student Pádraig Mac Carron, now at Oxford, who are applying the tools of their trade to works of epic literature, legend, and myth.

Nano-cone Textures Generate Extremely ‘Robust’ Water-Repellent Surfaces

15th July 2014

Read it.

“The idea that microscopic textures can impart a material with water-repellent properties has its origins in nature,” explained Brookhaven physicist and lead author Antonio Checco. “For example, the leaves of lotus plants and some insects’ exoskeletons have tiny-scale texturing designed to repel water by trapping air. This property, called ‘superhydrophobicity’ (or super-water-hating), enables water droplets to easily roll off, carrying dirt particles along with them.”

Mimicking this self-cleaning mechanism of nature is relevant for a wide range of applications, such as non-fouling, anti-icing, and antibacterial coatings. However, engineered superhydrophobic surfaces often fail under conditions involving high temperature, pressure, and humidity-such as automotive and aircraft windshields and steam turbine power generators-when the air trapped in the texture can be prone to escape. So scientists have been looking for schemes to improve the robustness of these surfaces by delaying or preventing air escape.

British Rocket Scientist Says He’s Designed a Better Saucepan

13th July 2014

Read it.

The “Flare Pan”, designed by Thomas Povey, is being manufactured and sold by Lakeland, a British kitchenware chain. It was introduced for sale Wednesday, but so far it seems to be available only in Britain, though it can be ordered through Lakeland’s website, with prices starting at about $85. Delivery won’t begin until Aug. 25.

Made from cast aluminum and sporting a series of “fins” around the bottom of the pan, the Flare Pan “channels heat from the flame across the bottom and up the sides of the pan, resulting in highly efficient, even heat distribution,” according to a release from Isis Innovation, which licenses technology developed at Oxford.

So it only works on gas cooktops. Less than optimally useful.

Check it out.

ORBIS: The Stanford Geospatial Network Model of the Roman World reconstructs the time cost and financial expense associated with a wide range of different types of travel in antiquity. The model is based on a simplified version of the giant network of cities, roads, rivers and sea lanes that framed movement across the Roman Empire. It broadly reflects conditions around 200 CE but also covers a few sites and roads created in late antiquity.

The model consists of 632 sites, most of them urban settlements but also including important promontories and mountain passes, and covers close to 10 million square kilometers (~4 million square miles) of terrestrial and maritime space. 301 sites serve as sea ports. The baseline road network encompasses 84,631 kilometers (52,587 miles) of road or desert tracks, complemented by 28,272 kilometers (17,567 miles) of navigable rivers and canals.

Japanese Farmer Builds High-Tech Indoor Veggie Factory

11th July 2014

Read it.

Humans have spent the last 10,000 years mastering agriculture. But a freak summer storm or bad drought can still mar many a well-planted harvest. Not anymore, says Japanese plant physiologist Shigeharu Shimamura, who has moved industrial-scale farming under the roof.

Working in Miyagi Prefecture in eastern Japan, which was badly hit by powerful earthquake and tsunamis in 2011, Shimamura turned a former Sony Corporation semiconductor factory into the world’s largest indoor farm illuminated by LEDs. The special LED fixtures were developed by GE and emit light at wavelengths optimal for plant growth.

The farm is nearly half the size of a football field (25,000 square feet). It opened on July and it is already producing 10,000 heads of lettuce per day. “I knew how to grow good vegetables biologically and I wanted to integrate that knowledge with hardware to make things happen,” Shimamura says.

Instead of 300 articles written by humans, the company’s new software will write 4,400 of them, each formatted for AP style, in mere seconds. It’s not the first time a company has tried out automatic writing: Last year, a reporter at The LA Times wrote an automated earthquake reporting program that combined pre-written sentences with automatic seismograph reports to report quakes just seconds after they happen. The natural language generation company Narrative Science has been churning out automated sports reporting for years.

Japan Pins Hopes on Floating Trains

7th July 2014

The company that operates the original bullet train, linking Tokyo to Osaka, intends to build a new line that cuts the journey between the two cities to little more than an hour—less than half the current time.

This wouldn’t be any old upgrade. At a projected cost of about $90 billion, it could be the world’s most expensive railway line to date. And it would be the first intercity train to use a technology called magnetic levitation, or maglev, which lifts the cars several inches off a concrete track and whisks them along at more than 500 kilometers, or roughly 310 miles, per hour—nearly 200 kilometers per hour more than the fastest bullet train, or Shinkansen.

Return of the European Bison

5th July 2014

Bison bonasus was driven to extinction in the wild across Europe in 1927 after decades of decline from hunting and habitat loss. But it has become that rare endangered species: a conservation success story.

There are now thousands in the wild, all descended from the 54 individuals in captivity when the last wild one was killed in Poland’s Bialowieza forest.

Despite the increase in numbers, the European bison is still rarer than other high profile species, such as the black rhino, even with the reintroductions. There are over 5,000 European bison, with about 3,200 in the wild.

The bricks — which are patent pending — are much like Lego in that they come in a variety of forms for different purposes and can easily connect together, with rows of knobs along the top of bricks that slot into voids along the bottom of other bricks. A special adhesive — which works like a super-strong double-sided sticky tape, a bit like 3M VHB — dispenses with the need for cement. They can be delivered to building sites in a kit complete with traditional doors and windows allowing for structures to be assembled with a minimum of debris and labour. Steel bars can be slotted through dedicated channels in the bricks to provide the same support as traditionally reinforced concrete.

Soon Everyone Will be an Electric Company

5th July 2014

Read it.

In the not-too-distant future, everyone could be an electric company, selling power into the grid just like the owners of giant generating plants.

The idea of powering the electric grid from a multitude of sources is called distributed generation. Homeowners can already buy solar generators and furnaces that simultaneously produce heat and electricity. On the horizon are home battery systems that could let homeowners store solar power generated during the day for use at night.

Distributed generation isn’t pie-in-the sky — the know-how exists to build these systems. But the technology is held back by cost and by regulations that don’t allow for tiny contributions to the power grid. Federal energy experts figure costs will drop and regulatory issues will be overcome, and that the amount of electricity homes and businesses produce through distributed generation could roughly double over the next 25 years. That’s not enough to replace big generating plants, but enough to have a big impact.

Stanford Researchers Might Have Found a Way to Create a Graphene-Like Material That Is Also an Insulator

2nd July 2014

Read it.

A big problem with graphene, a super-strong, atom-thick material that could soon be used to build a new generation of thin and flexible electronics, is that it constantly conducts electricity. Electronics need to be able to turn the flow on and off, which is not currently possible with a pure sheet of graphene.

Stanford researchers wrote in Nature Communications Tuesday that they have come up with one of a growing number of alternatives. It might not be as strong or thin as graphene, but the three-atom-thick material they modeled has the unusual feature of being able to switch between two different atomic structures, allowing it to turn the flow of electricity on or off like a light switch.

One of the biggest problems with printing human meat was the creation of blood vessels and ventricles. Making a solid mass of flesh was easy but adding a way to pump blood and other nutrients through the flesh was more difficult. Now researchers at the University of Sydney, Harvard, Stanford and MIT, have solved some of these problems by creating a skeleton of vessels and then growing human cells around them. Once the vessels are stable, they are able to dissolve the 3D printed material.

As Olympians go for the gold in Vancouver, even the steeliest are likely to experience that familiar feeling of “butterflies” in the stomach. Underlying this sensation is an often-overlooked network of neurons lining our guts that is so extensive some scientists have nicknamed it our “second brain”.

A deeper understanding of this mass of neural tissue, filled with important neurotransmitters, is revealing that it does much more than merely handle digestion or inflict the occasional nervous pang. The little brain in our innards, in connection with the big one in our skulls, partly determines our mental state and plays key roles in certain diseases throughout the body.
