By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away, yielding an unprecedented amount of data for such observations.

The resolution at which they were able to observe this highly luminescent active galactic nucleus (AGN) has given them direct confirmation of how… read more

30-year robot project pitched

August 21, 2003

Japanese researchers in robot technology are advocating a grand project, under which the government would spend 50 billion yen a year over three decades to develop a humanoid robot with the mental, physical and emotional capacity of a 5-year-old human.

35 hours of video per minute uploaded to YouTube

November 12, 2010

(YouTube blog)

More than 35 hours of video are uploaded to YouTube per minute, or 50,400 hours uploaded every day — the equivalent of more than 176,000 full-length Hollywood releases every week.

Here are some of the factors contributing to the growth:

  • The time limit for videos uploaded by users increased by 50% from 10 to 15 minutes.
  • The upload file size increased over the last few

3D acoustic cloaking device makes objects undetectable with sound

March 13, 2014

Using a few perforated sheets of plastic and extensive computation, Duke University engineers have demonstrated the world’s first three-dimensional acoustic cloak.

The new device reroutes sound waves to create the impression that both the cloak and anything beneath it are not there.

The acoustic cloaking device works in three dimensions, no matter which direction the sound is coming from or where the observer is located, and holds potential… read more

3D art for all: Ready to print

May 16, 2011

Makerbot, a leading company in the field of 3D printing that has sold over 4,500 machines, has been putting the ability to manufacture custom plastic “prints” in the hands of anyone with $1,300 to buy one of their machines. The technology, called “3D printing” or “rapid prototyping,” has existed for years, but is only recently gaining a foothold among everyday tinkerers.

3D audio system developed by MP3 pioneer

July 28, 2004

A sound system that creates immersive, three-dimensional audio for everyone in a room has been developed by one of the creators of the MP3 audio format.

It uses a principle known as “wave field synthesis” to create complex audio illusions for everyone within a defined space. Computers are used to predict the way multiple sound waves will interact with each other within a space. Then, a multitude of small… read more

3D bio-printers to print skin and body parts

February 25, 2011

Scientists are developing 3D “bioprinters” that will be able to print out skin, cartilage, bone, and other body parts.

Professor James Yoo, from the Institute of Regenerative Medicine at Wake Forest University is developing a system that will allow them to print skin directly onto burn wounds. The bioprinter has a built-in laser scanner that scans the wound and determines its depth and area. The scan is converted into… read more

3D chip stacking to take Moore’s Law past 2020

March 12, 2010

3D Microchips

By combining 3D-stack-architecture of multiple cores with hair-thin, liquid-cooled microchannels, IBM and Swiss Federal Institute of Technology Zurich hope to extend Moore’s law for another decade or more.

3D chip stacks with interlayer cooling overcome the bandwidth bottleneck between core and cache memory and allow for systems with a much higher efficiency, so supercomputers won’t consume too much energy to be affordable.

To solve the… read more

3D copying makes Michelangelos of the masses

Cosmo Wenman went to the J. Paul Getty Museum in Los Angeles, took hundreds of pictures, documenting busts and reliefs from every accessible angle, and turned the photos into three-dimensional digital maps, using a free program called Autodesk 123D Catch.

Then he used the maps to print miniature plastic replicas on the $2,000 MakerBot 3-D printer in his home office.

And he… read more

3D counterpart to graphene discovered [UPDATE]

Promises faster transistors and more compact hard drives
January 20, 2014

DOE Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have discovered that sodium bismuthide can exist as a form of matter called a “three-dimensional topological Dirac semi-metal” (3DTDS).

“A 3DTDS is a natural three-dimensional counterpart to graphene with similar or even better electron mobility and velocity,” says Yulin Chen, a physicist with Berkeley Lab’s Advanced Light Source (ALS) when he initiated the study that led to this discovery,… read more

3D ‘Crystal Ball’ Monitors

May 1, 2003

Perspecta, a new display technology using a rotating disk, provides a high-resolution 3D representation of an object that can be viewed from 360 degrees around the display, without the need for special goggles.

3D Display Offers Glimpse of Future Media

November 10, 2008

A 3D display system, developed by University of Southern California researchers, could one day transform visual entertainment.

The 3D display can project both virtual as well as real images from a recorded movie, is autosterescopic (viewers don´t need to wear special viewing glasses to see the 3D effects), and is also omnidirectional, so that multiple viewers can watch the display from all directions and heights.

3D graphene could replace expensive platinum in solar cells

Michigan Technological University, scientists have replaced expensive ($1,500 an ounce) platinum in solar cells with low-cost 3D graphene.

Regular graphene is a two-dimensional form of carbon. Yun Hang Hu, the Charles and Caroll McArthur Professor of Materials Science and Engineering at MTU, and his team invented a way to synthesize a 3D version, with a honeycomb-like structure.

The 3D graphene had excellent conductivity and high… read more

A team of scientists from the University of California, Los Angeles (UCLA) and Northwestern University has produced 3-D images and videos of a tiny platinum nanoparticle at atomic resolution that reveal new details of defects in nanomaterials that have not been seen before.

Prior to this work, scientists only had flat, two-dimensional images with which to view the arrangement of atoms.

3D IR images now in full color

August 7, 2013

Spectro-microtomographic images of a human hair show absorptions of protein (red) and phospholipid (blue-green). Center, the medulla is observed to have little protein. Bottom, the medulla has higher concentrations of phospholipids.

Researchers have created a non-destructive 3D imaging technique that provides molecular-level chemical information of unprecedented detail on biological and other specimens with no need to stain or alter the specimen.

Developed by researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of Wisconsin-Milwaukee (UWM), the technique combines Fourier Transform Infrared (FTIR) spectroscopy with computed tomography (CT-scans).
