Yes, congenital blind can learn to link vision and touch

April 12, 2011

Sense of Touch

Researchers at MIT have shown that the brain does not have an innate ability to connect different types of sensory input, but can quickly learn to do so.

The researchers tested five children with treatable forms of blindness to answer the question: could they visually distinguish between objects that they could previously only identify by touch? This question was first raised by scientist William Molyneux… read more

Yeast-powered fuel cell feeds on human blood

April 2, 2009

Yeast cells feeding on the glucose in human blood might one day power implants such as pacemakers, eliminating the need for regular operations to replace batteries.

University of British Columbia scientists have developed tiny microbial fuel cells by encapsulating yeast cells in a flexible capsule.

Yeast-Based Oral Diabetes Treatment Discovered

January 3, 2008

University of Haifa researchers have discovered a yeast-derived substance called Glucose Tolerance Factor (GTF) that acts similarly to insulin and may become an oral treatment for diabetes and its complications.

In the studies–done on cell cultures and on diabetic rats–GTF inhibited oxidation processes that could cause atherosclerosis and further complications like strokes and heart attacks. When GTF was given at the early stage of the disease, it could prevent… read more

Yeast protein wires supercomputers

April 2, 2003

Investigators are experimenting with biological materials that can arrange themselves into strings spontaneously, using genetically engineered yeast amyloids or prions. These strands would be stable and would serve as the backbone for metal to attach onto, creating wires for self-assembling electronic circuits.

Yeast and bacterium turned into gasoline factory

April 21, 2009

University of California, San Francisco researchers have developed a low-temperature, low-cost, carbon-neutral process for producing gasoline more cheaply than oil.

They use A. fermentans bacteria to convert cellulose into acetate, which is converted into methyl halides by the genetically engineered yeast.

Year of the Robot

January 4, 2006

Last year (2005), the news was full of stories about robots. On the industrial side, the North American robotics industry posted 30% growth through the first three quarters (the latest data available).

In other, less traditional markets such as law enforcement, there were monthly reports of mobile robots used for bomb detection and disposal in the U.S. and across the world. Unmanned robotic vehicles have been used for assessing… read more

Yale scientists decipher ‘wiring pattern’ of cell signaling networks

December 2, 2005

A team of scientists at Yale University has completed the first comprehensive map of the proteins and kinase signaling network that controls how cells of higher organisms operate, according to a report this week in the journal Nature.

Protein kinases act as regulator switches and modify their target proteins by adding a phosphate group to them. This process, called “phosphorylation,” results in altered activity of the phosphorylated protein. It… read more

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 and wait for others to post responses. To flag inaccuracies, individuals can rate the responses based on quality.

‘Yahoo research uses artificial intelligence everywhere’

January 21, 2007

AI is being used in every part of Yahoo’s research, especially since they collect over 12 terabytes of data everyday, according to Ronald J Brachman, vice-president of Worldwide Research Operations.

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
