Why you should go paperless in 2013

January 3, 2013

Are you still printing things out? Really?

Amazingly, the average office worker still uses about 10,000 sheets of paper per year, the EPA says.

To make a new push for a really paperless office, the “Paperless Coalition,” which includes Google Drive, HelloFax, Manilla, HelloSign, Expensify, Xero and Fujitsu ScanSnap, has launched a… read more

Iris (Siri for Android) released

October 24, 2011

irisandroid

Iris for Android, a Siri lookalike, is now available on the Android Market, Gizmodo reports.

Iris (Siri backwards), emulates what Siri on the iPhone 4S does: you tap a mic, you talk, and Siri responds to you. Siri could lead to a real AI, Wired blogger Jon Stokes says.

The same SRI International defense project that gave birth to Siri —  CALO… read more

Clothes will sew themselves in DARPA’s sweat-free sweatshops

sweatshop

DARPA has awarded $1.25 million to fully automate the sewing process, Wired Danger Room reports.

One 2010 estimate put the military’s annual clothing budget at $4 billion dollars.

SoftWear Automation Inc., has so far developed “a conceptual” version of the automated system. According to its website, it is a robotic system that relies on an extremely precise monitoring of a given fabric’s “thread count”… read more

Are restrictions to scientific research costing lives?

September 6, 2012

CensorsOnCampusSep12Cover

In “Censors on Campus,” Index on Censorship magazine asks whether lives might be saved by making vital research freely available.

Some parts of Asia and Africa the fight against malaria is severely hampered because doctors and researchers are denied full access to the 3,000 articles published on the disease each year. At the same time, scientists living and working in developing countries are prevented from becoming global… read more

Intelligence could not be linked to 12 specific genetic variants, contradicting studies

October 4, 2012

IQ_curve

Most of the specific genes long thought to be linked to intelligence probably have no bearing on one’s IQ, and new study by psychological scientist Christopher Chabris of Union College has revealed.

Chabris and David Laibson, a Harvard economist, led an international team of researchers that analyzed a dozen genes using large data sets that included both intelligence testing and genetic data.

In nearly every case, the researchers found… read more

First 3D ghost images from a single pixel

January 29, 2013

3D ghost imaging

Shanghai Institute of Optics and Fine Mechanics in China physicists have designed and built a remote-sensing “ghost imaging” device that uses a single pixel to record three-dimensional images, MIT Technology Review reports.

Ghost imaging is the extraordinary technique of bouncing a laser beam off an object and making high quality images from the reflected light using a single pixel. This single pixel is used to record data… read more

Metamaterial flat lens projects 3D UV images of objects

May 29, 2013

ultraviolet (UV) metamaterial formed of alternating nanolayers of silver

Scientists working at the National Institute of Standards and Technology (NIST) have demonstrated a new type of lens that bends and focuses ultraviolet (UV) light in such an unusual way that it can create ghostly, 3D images of objects that float in free space.

The easy-to-build lens could lead to improved photolithography, nanoscale manipulation and manufacturing, and even high-resolution three-dimensional imaging, as well as a… read more

Help U.S. economy with visas for the best and brightest

To see the results of self-defeating U.S. immigration policies, you need only open your browser to www.canadavisa.com, where you’ll see a shrewd neighbor fishing for talent at U.S. expense.

At the top of the website, in large print, is the question: “Currently on an H1B Visa or otherwise working or studying in the United States?”

How to create a spray-paint battery

Turn any surface into a battery
June 29, 2012

Li-ion battery

lithium-ion battery that can be painted on virtually any surface has been developed by Rice University researchers.

The rechargeable battery, created in the lab of Rice materials scientist Pulickel Ajayan, consists of spray-painted layers, each representing the components in a traditional battery.

“This means traditional packaging for batteries has given way to a much more flexible approach that allows all kinds of new design and integration possibilities… read more

Proteins remember the past to predict the future

October 5, 2012

Motor_Proteins

The most efficient machines remember what has happened to them, and use that memory to predict what the future holds.

That is the conclusion of a theoretical study by Susanne Still, a computer scientist at the University of Hawaii at Manoa and her colleagues, and it should apply equally to “machines” ranging from molecular enzymes to computers, Nature News reports. The finding could help to improve scientific… read more

‘Rogue’ asteroids may be the norm

February 3, 2014

eso_asteroid

A new map of asteroids developed by researchers from MIT and the Paris Observatory charts the size, composition, and location of more than 100,000 asteroids throughout the solar system, and shows that rogue asteroids are more common than previously thought.

Particularly in the solar system’s main asteroid belt — between Mars and Jupiter — the researchers found a compositionally diverse mix of asteroids.

The new asteroid… read more

Mathematicians at UC Davis have come up with a new way to crinkle up the fabric of space-time — at least in theory.

“We show that space-time cannot be locally flat at a point where two shock waves collide,” said Blake Temple, professor of mathematics at UC Davis. “This is a new kind of singularity in general relativity.”

About two hours after landing on Mars and beaming back its first image, NASA’s Curiosity rover transmitted a higher-resolution image of its new Martian home, Gale Crater.

“Curiosity’s landing site is beginning to come into focus,” said John Grotzinger, project manager of NASA’s Mars Science Laboratory mission, at the California Institute of Technology in Pasadena.

“In the image, we are looking to the northwest. What you see on… read more

Neural stem cells regenerate axons in severe spinal cord injury

New relay circuits, formed across sites of complete spinal transaction, result in functional recovery in rats

In a study at the University of California, San Diego and VA San Diego Healthcare, researchers were able to regenerate “an astonishing degree” of axonal growth at the site of severe spinal cord injury in rats.

Their research revealed that early stage neurons have the ability to survive and extend axons to form new, functional neuronal relays across an injury site in the adult central… read more
