Tuesday’s launch of a new year-long test of “smart car” technology conducted by the University of Michigan Transportation Research Institute is designed to save lives and reduce injuries among American motorists.

The researchers plan to install wireless communication devices on nearly 3,000 vehicles that will let passenger cars, commercial trucks, and transit buses “talk” to each other, as well as to traffic lights and other… read more

A 3-D View of the Brain

August 6, 2007

Researchers at Thomas Jefferson University Hospital have developed software that integrates data from multiple imaging technologies to create an interactive 3-D map of the brain.

The new imaging software collates data from different types of brain-imaging methods, including conventional magnetic resonance imaging (MRI), functional MRI (fMRI), and diffusion-tensor imaging (DTI). The MRI gives details on the anatomy, fMRI provides information on the activated areas of the brain, and DTI… read more

A $3.5 Billion Effort Aims to Help Tech Start-Ups

February 24, 2010

In an initiative called the Invest in America Alliance, Intel and 24 venture capital firms plan to invest $3.5 billion in American start-ups over the next two years.

In addition, Intel, Google, Cisco Systems, Microsoft and 13 other employers pledged to add jobs in 2010, by hiring 10,500 graduates of American colleges, largely those with computer science and engineering degrees.

Fewer than 10 percent of college graduates in… read more

A 360-degree view of the world

Paranoids alert
December 13, 2012

FlyViz

Have you ever dreamed of having eyes in the back of your head?

Yeah, we haven’t either, but FlyVIZ, designed by French engineers, lets you experience a real-time 360° vision of your surroundings. It combines a panoramic image acquisition system (positioned on top of the your head) with a head-mounted display (HMD) and a laptop for transforming the fly-eye images in real time into something humans can… read more

A 3D image of an individual protein

January 26, 2012

Apolipoprotein-images

Lawrence Berkeley National Laboratory (Berkeley Lab) scientists have created detailed models of a single protein using electron microscopic images.

Scientists routinely create models of proteins using X-ray diffraction, nuclear magnetic resonance, and conventional cryo-electron microscope (cryoEM) imaging. But these models require computer “averaging” of data from analysis of thousands, or even millions of like molecules, because it is so difficult to resolve the features of… read more

A 3D light switch for the brain

New device for delivering light to individual neurons could one day help treat Parkinson's disease, epilepsy; aid understanding of consciousness, how memories form

A new fiber-optic device created by MIT biologists and engineers is the first tool that can deliver 1000 precise points of light to a 3D section of living brain tissue matter smaller than a sugar cube.

This is a step forward for a technique called optogenetics, which uses gene treatments to turn individual brain cells on and off with light.

Scientists can use this new 3D… read more

A 3D microscopic device for high-speed processing of infrared light

Rice University researchers have produced a micron-scale spatial light modulator (SLM) like those used in sensing and imaging devices, but with the potential to run orders of magnitude faster.

Unlike other devices that use two-dimensional semiconducting chips, the Rice chips work in three-dimensional “free space.”

The chips promise to speed up applications that are free-space based, such as imaging, display, holographics, metrology and remote… read more

A 3D printer to turn waste plastic into composting toilets, rainwater harvesting systems

3dprinting_machine_3d4dchallenge

A University of Washington team claimed a $100,000 prize in the first 3D4D Challenge, an international contest to use 3-D printing for social benefit in the developing world.

The three undergraduates won to form a company that will work with partners in Oaxaca, Mexico.

Matthew Rogge, a mechanical engineering grad student, proposed to use giant 3-D printers to create composting latrines that areread more

You can expect to see the third dimension coming to a tablet soon, Technology Review Hello World reports, such as a forthcoming Qualcomm tablet that uses MasterImage’s open-source 3-D display, which supports iOS, Android, or Windows.

A 3D window into living cells, no dye required

3d_imaging_living_cells

University of Illinois researchers have developed a new imaging technique that needs no dyes or other chemicals, yet renders high-resolution, three-dimensional, quantitative imagery of cells and their internal structures using conventional microscopes and white light.

Called white-light diffraction tomography (WDT), the imaging technique opens a window into the life of a cell without disturbing it and could allow cellular biologists unprecedented insight into cellular processes, drug effects and stem cell… read more

Space architects have unveiled a concept for a 3D-printed Moon base called SinterHab near the lunar south pole. Modules would be constructed from lunar dust by microwave sintering and contour crafting, built by a large NASA spider robot.

Unlike an earlier, more bulky concept using a mobile printing array of nozzles on a 6 meter frame to spray a binding solution (glue) onto… read more

A 3D-printed navy?

Instead a carrying spare parts, space-constrained U.S. Navy ships in the future might carry 3-D printers and bags of various powdered ingredients, and simply download the design files needed to print items as necessary, according to the Armed Forces Journal,

“Perhaps closer at hand is a distributed global production network in which sailors and Marines send an email with a digital scan or design for a

3doodler

Have you ever wished you could just draw a object in the air and have it magically printed out? 

WoobbleWorks has created 3Doodler (a Kickstarter project), the world’s first “3D printing pen” to do just that.

As you draw, it extrudes ABS plastic (the material used by many 3D printers) in the air or on surfaces — no software or computers required.
