Yale researchers use genetic code to engineer a living protein

August 26, 2011

Yale University researchers have successfully re-engineered the protein-making machinery in bacteria, which promises to revolutionize the study and treatment of a variety of diseases.

“Essentially, we have expanded the genetic code of E. coli, which allows us to synthesize special forms of proteins that can mimic natural or disease states,” said Jesse Rinehart of the Department of Cellular and Molecular Physiology and co-corresponding author of the research published in the… read more

Yahoo’s human touch to answers

December 9, 2005

Yahoo has launched Yahoo Answers, which allows users to get their questions answered online for free by volunteers.

Users can submit questions on any topic at answers.yahoo.com and wait for others to post responses. To flag inaccuracies, individuals can rate the responses based on quality.

‘Yahoo research uses artificial intelligence everywhere’

Yahoo passes Google in search index capacity

August 9, 2005

Yahoo says it now indexes more than 20 billion documents and images. That’s almost twice the 11.3 billion Google publicly says it currently spans.

Of the 20 billion elements in Yahoo’s database, 19 billion are documents, 1.5 billion images and more than 50 million audio and video files, the company said.

Yahoo Meets Searchers’ Mindsets

June 2, 2005

Yahoo has developed a smart search tool, Mindset, that adjusts results based on how commercial they are.

When people search using Mindset, a simple slider appears on top of the search results. As the slider is moved closer to shopping, commercial listings rise to the top. If it’s moved in the other direction, toward researching, the results weigh toward educational, community and informational sites.

Yahoo Debuts Audio Search

August 5, 2005

Yahoo Audio Search allows users to peruse a list of 50 million music, voice and other files for free.

Yahoo Audio Search also enables independent publishers to submit content to the index through Media Really Simple Syndication (Media RSS), providing users with open access to original and timely audio content, according to the company.

Yacht voyage yields array of new genes

March 14, 2007

A yacht voyage that genome pioneer Craig Venter took around the world has turned up a startling array of new genes and new gene families.

They have found genes that help microbes use the sun’s energy in new ways, genes that help them use nitrogen, and genes that protect organisms from ultraviolet light, and have identified more than 6 million new proteins.

Y-shaped nanotubes are ready-made transistors

August 16, 2005

Y-shaped carbon nanotubes grown with iron-titanium particles are easily made and act as remarkably efficient electronic transistors that are 100 times smaller than the transistors used in today’s microprocessors.

So they could be used to create microchips several orders of magnitude more powerful than the ones used in computers today, with no increase in chip size. The Y-shaped nanotubes measure just tens of nanometers in size. Eventually, they could… read more

Astronomers have probed closer than ever to a supermassive black hole estimated to have the mass of about 3 to 5 million solar masses, at the core of a distant active galaxy.

XML-based ‘Flare’ programming language project launched

July 24, 2001

The Singularity Institute for Artificial Intelligence has launched the Flare programming language project, headed by programmer Dmitriy Myshkin.

Flare is proposed as a fundamentally new programming language expected to be useful for AI research (among other uses). “Program objects and program code can be represented as well-formed XML, enabling a wide variety of new design patterns and language idioms,” says the announcement.

“Current programming… read more

xMax sparks low power wireless revolution

November 7, 2005

xG Technology has demonstrated wireless broadband 1000 times more efficient than WiMax, and claims the technique could also make wireless LANs that will run for years on watch batteries and could allow anyone to set up as a wireless ISP.
