An atom-thick Rice Owl (scale bar equals 100 micrometers) was created to show the ability to make fine patterns in hybrid graphene/hexagonal boron nitride (hBN). In this image, the owl is hBN and the lighter material around it is graphene. The ability to pattern a conductor (graphene) and insulator (hBN) into a single layer may advance the ability to shrink electronic devices. (Credit: Zheng Liu/Rice University)

Jan. 27, 2013 — Rice University scientists have taken an important step toward the creation of two-dimensional electronics with a process to make patterns in atom-thick layers that combine a conductor and an insulator.

The materials at play -- graphene and hexagonal boron nitride -- have been...

Jan. 23, 2013 — Researchers at the EMBL-European Bioinformatics Institute (EMBL-EBI) have created a way to store data in the form of DNA – a material that lasts for tens of thousands of years. The new method, published January 23 in the journal Nature, makes it possible to store at least 100 million hours of high-definition video in about a cup of DNA.

There is a lot of digital...

Video analysis: Detecting text every which way

  • PDF
Jan. 3, 2013 — Software that detects and extracts text from within video frames, making it searchable, is set to make a vast resource even more valuable.

As video recording technology improves in performance and falls in price, ever-more events are being captured within video files. If all of this footage could be searched effectively, it would represent an invaluable information repository. One option to help catalogue large video databases is to extract text, such as street...

TechAndComputer (Dec. 5, 2012) — The Centre of Microsystems Technology (CMST), imec's associated laboratory at Ghent University (Belgium), has developed an innovative spherical curved LCD display, which can be embedded in contact lenses. The first step toward fully pixilated contact lens displays, this achievement has potential wide-spread applications in medical and cosmetic domains.

Unlike LED-based...
