TechAndComputer (May 7, 2011) — Music producers have for decades had electronics tricks at their disposal for improving a recorded vocal performance. They can add a little reverb or echo to bolster a weak rendition, use effects such as phasing and delay to add color to the vocal, fix duff notes with auto-tuning or even reprogram a whole melody line in software. In recent years, voice synthesis for converting text to spoken word has improved...

College students' use of Kindle DX points to e-reader’s role in academia

  • PDF
TechAndComputer (May 2, 2011) — A study of how University of Washington graduate students integrated an Amazon Kindle DX into their course reading provides the first long-term investigation of e-readers in higher education. While some of the study's findings were expected -- students want improved support for taking notes, checking references and viewing figures -- the authors also found that allowing people to switch between reading styles, and...

Origami not just for paper anymore: DNA, folded into complex shapes, could have a big impact on nanotechnology

  • PDF
TechAndComputer (Apr. 27, 2011) — While the primary job of DNA in cells is to carry genetic information from one generation to the next, some scientists also see the highly stable and programmable molecule as an ideal building material for nanoscale structures that could be used to deliver drugs, act as biosensors, perform artificial photosynthesis and more.

Trying to build DNA structures on a large scale was once considered unthinkable. But...

New sensor glove may help stroke patients recover mobility

  • PDF
TechAndComputer (Apr. 26, 2011) — People who have strokes are often left with moderate to severe physical impairments. Now, thanks to a glove developed at McGill, stroke patients may be able to recover hand motion by playing video games. The Biomedical Sensor Glove was developed by four final-year McGill Mechanical Engineering undergrads under the supervision of Professor Rosaire Mongrain.

It is designed to allow patients to exercise in their own...
