Low-cost graphene-based biosensor chip detects DNA mutations in real time

One of the most common indicators of many diseases and cancer in blood is the presence of a genetic mutation known as a single nucleotide polymorphism (SNP). Unfortunately, to date such tests for SNPs are slow, cumbersome and – above all – expensive. Now a team of researchers from the University of California, San Diego (UCSD) have developed a new graphene-based sensor that promises to deliver test results easily, in real time, and inexpensively. The researchers believe this could be a breakthrough in the early detection and screening for many life-threatening illnesses.Read More

Sensor detects signs of cancer, Alzheimer's, and Parkinson's

Cancer and neurodegenerative diseases like Alzheimer's and Parkinson's are all able to be better treated if detected early. Unfortunately, this is not always the case as symptoms may not appear until these diseases are well established. To help counteract this problem, scientists at the National Nanotechnology Laboratory (LNNano) in Brazil have created a biosensor capable of rapidly detecting molecules specifically linked to various cancers and neurological diseases.Read More

New records bring super-powerful quantum computers closer to reality

In what are claimed to be new world records, two teams working in parallel at the University of New South Wales (UNSW) in Australia have each found solutions to problems facing the advancement of silicon quantum computers. The first involves processing quantum data with an accuracy above 99 percent, while the second is the ability to store coherent quantum information for more than thirty seconds. Both of these records represent milestones in the eventual realization of super-powerful quantum computers.Read More
