At the heart of computing are tiny crystals that transmit and store digital information’s ones and zeroes. Today these are hard and brittle materials. But cheap, flexible, nontoxic organic molecules may play a role in the future of hardware.

A team led by the University of Washington in Seattle and the Southeast University in China discovered a molecule that shows promise as an organic alternative to today’s silicon-based semiconductors. The findings, published this week in the journal Science, display properties that make it well suited to a wide range of applications in memory, sensing and low-cost energy storage. (more…)

Safeguards Needed for Tissue Donors

Donors to biobanks – vast collections of human tissue samples that scientists hope will lead to new treatments for diseases – have a right to basic information about how their donations may be used, a Michigan State University ethicist argues in a new paper.

The idea behind biobanks is that a repository with hundreds of thousands of samples, each linked to medical records and other health information, can yield discoveries smaller data sets can’t match. Once samples are collected, researchers in many fields can use the data repeatedly. (more…)

Reconcilable Differences: Study Uncovers the Common Ground of Scientific Opposites

Searching for common elements in seemingly incompatible scientific theories may lead to the discovery of new ones that revolutionize our understanding of the world.

Such is the idea behind a mathematical framework Princeton University researchers developed that strips away the differences between scientific laws and theories to reveal how the ideas are compatible. In a recent report in the journal Physical Review Letters, the authors explain how the mathematical model finds common ground between the famously at-odds physics equations that govern classical and quantum mechanics.

Data analytics helps organizations hunt for cyber attacks

ARMONK, N.Y. – 31 Jan 2013: Advanced attacks, widespread fraud and the pervasive use of social media, mobile and cloud computing are drastically altering the security landscape. As organizations increasingly need to manage Big Data, the way that corporate data needs to be protected is rapidly changing. (more…)

Internet Banging: Gangs Use Social Media to Trade Insults, Threats

ANN ARBOR — Gangs now occupy two spaces: the streets and the Internet.

A new University of Michigan study reports that, in addition to carrying guns, gang members have armed themselves with social media sites such as Twitter, Facebook and YouTube to incite dares, trade insults or make threats that may result in homicide or other crimes.

Researchers have described this new interaction as “Internet banging.” They examine several factors, including the role of hip-hop music in this phenomenon and urban masculinity’s influence on social media behavior. (more…)

A Better Way to Culture Central Nervous Cells

A protein associated with neuron damage in Alzheimer’s patients provides a superior scaffold for growing central nervous system cells in the lab. The findings could have clinical implications for producing neural implants and offers new insights on the complex link between the apoE4 apolipoprotein and Alzheimer’s disease. Results appear in the journal Biomaterials. (more…)
