New chip architecture may provide foundation for quantum computer

Science Daily - Tue, 05/05/2015 - 3:19pm
Quantum computers are in theory capable of simulating the interactions of molecules at a level of detail far beyond the capabilities of even the largest supercomputers today. Such simulations could revolutionize chemistry, biology and material science, but the development of quantum computers has been limited by the ability to increase the number of quantum bits, or qubits, that encode, store and access large amounts of data.

Chest strap heart rate monitor

Science Daily - Tue, 05/05/2015 - 3:12pm
Scientists have developed a novel chest strap device for the long-term monitoring of patients with heart and circulatory problems. What is special about the new system is that it records an electrocardiogram (ECG) of the wearer. It is also self-moistening, which is essential for reliable signal monitoring.

How the NSA Converts Spoken Words Into Searchable Text

Slashdot - Tue, 05/05/2015 - 3:00pm
Presto Vivace writes: Dan Froomkin reports at The Intercept: "Though perfect transcription of natural conversation apparently remains the Intelligence Community's 'holy grail,' the Snowden documents describe extensive use of keyword searching as well as computer programs designed to analyze and 'extract' the content of voice conversations, and even use sophisticated algorithms to flag conversations of interest." I am torn between admiration of the technical brilliance of building software like this and horror as to how it is being used. It can't just be my brother and me who like to salt all phone conversations with interesting keywords.

Treating gum disease reduces prostate symptoms, researchers find

Science Daily - Tue, 05/05/2015 - 2:24pm
Treating gum disease reduced symptoms of prostate inflammation, called prostatitis, report researchers. Previous studies have found a link between gum disease and prostatitis, a disease that inflames the gland that produces semen. Inflammation can make urination difficult.

America's best teachers get creative

Science Daily - Tue, 05/05/2015 - 2:24pm
America's best teachers rap their algebra lessons, use music to teach Kafka and find other ways to use their own creative interests to teach their students, finds a new study. Examining the classroom practices of National Teacher of the Year winners and finalists, the study suggests successful educators aren't afraid to push the boundaries by incorporating real world, cross-disciplinary themes into their lessons.

Nonstop shopping: Impact of mobile technology on purchasing patterns

Science Daily - Tue, 05/05/2015 - 2:23pm
Customers who adopted mobile technology for their grocery shopping shopped more often and placed larger orders, research shows. The data was collected between 2011 and 2013 from an Internet-only retail grocer that operates mainly in the northeast US. Although 70 percent of transactions with the grocer were still being conducted via personal computer during this period, the researchers were able to identify key patterns among customers who were increasingly using mobile technology.

'Tangles' trigger early-stage Alzheimer's abnormalities in neocortical networks

Science Daily - Tue, 05/05/2015 - 2:23pm
A ground-breaking study has now, for the first time, characterized early-stage changes that occur inside individual, Alzheimer's-affected cells in the intact brain. Remarkably, the study indicates that even if only a small number of cells is affected, the result is a reduction of electrical activity throughout the cerebral cortex -- the area of the brain that serves as the center of higher mental function and cognition.

Scientists look through the mirror to reveal secrets of a new drug

Science Daily - Tue, 05/05/2015 - 2:23pm
Research results can help develop anti-inflammatory drugs, scientists say. Results from recent study revealed a nucleic acid molecule that has the perfectly reversed geometry as compared to a naturally occurring RNA/DNA molecule. However, this unusual molecule still interacts strongly with the normal C5a protein built with naturally occurring amino acids, thereby illustrating beautifully how the two sides of the mirror can be reunited and leaving us to wonder about the possibility of a world where both sides of the mirror would have coexisted in harmony.

'Microcombing' creates stronger, more conductive carbon nanotube films

Science Daily - Tue, 05/05/2015 - 2:23pm
Researchers have developed an inexpensive technique called 'microcombing' to align carbon nanotubes (CNTs), which can be used to create large, pure CNT films that are stronger than any previous such films. The technique also improves the electrical conductivity that makes these films attractive for use in electronic and aerospace applications.

Accelerated brain aging in type 1 diabetes related to cognitive complications

Science Daily - Tue, 05/05/2015 - 2:23pm
The brains of people with type 1 diabetes show signs of accelerated aging that correlate with slower information processing, according to research. The findings indicate that clinicians should consider screening middle-aged patients with type 1 diabetes for cognitive difficulties. If progressive, these changes could influence their ability to manage their diabetes.
