New Organic Material to Speed Internet Access

The next time an overnight snow begins to fall, take two bricks and place them side by side a few inches apart in your yard. In the morning, the bricks will be covered with snow and barely discernible. The snowflakes will have filled every vacant space between and around the bricks. What you will see, says Ivan Biaggio, an associate professor of physics at Lehigh University resembles a phenomenon that, when it occurs at the smallest of scales on an integrated optical circuit, could hasten the day when the Internet works at superfast speeds. Biaggio, is part of an international team of researchers that has developed an organic material with an unprecedented combination of high optical quality and strong ability to mediate light-light interaction and has engineered the integration of this material with silicon technology so it can be used in optical telecommunication devices. The material, which is composed of small organic molecules with high nonlinear optical susceptibilities,...

Biotic Man to Aid Drug Research

GE's technology development arm General Electric Global Research has announced its plans to develop a virtual human by signing an agreement with TMTI, Transformational Medical Technologies Initiative. Also supported by DTRA, Defense Threat Reduction Agency of the Department of Defense, the project includes a computer aided model to accelerate the development of new drugs against biological attacks. The virtual human project dubbed as Biotic Man, is a Physiologically Based Pharmacokinetic (PBPK) software tool, which will be used to better understand the effects of a new drug much earlier than clinical experiments. PBPK will digitally model bacteria, viruses and other infection agents. John Graf, Principal Investigator on the project for GE Global Research has said, GE's Biotic Man project is all about speed. The goal is to enable faster development of drugs to respond to new biological threats. This new software tool also could have broad impact across the pharmaceutical ...

Ranking Systems and Vote Spam

As the number of social networks increase, so does their importance for bloggers in particular and businesses in general to promote their content through them. It is critical to understand the metrics used to use social media effectively . One particular industry that has high stakes in this is the search engines as social media sources provide an effective alternative to traditional web search by directly connecting users with the information needs to users willing to share the information. For example, users can post questions or new items, and rely on other users to comment or rank the content (e.g., sites such as Slashdot or Digg) or rank the popularity of users (like Twitter). While the responses could be excellent, the quality could vary greatly. Hence, user feedback, such as voting, or rating the content, has become a crucial aspect of the effectiveness of the community as demonstrated by the paper, A Few Bad Votes Too Many? Towards Robust Ranking in Social Media [pdf] by Jiang...

Evolutionary Cognitive Neuroscience

Image
Complexity (the number of ways-hows-and-whys a system can act) may become an anachronism as novel research demystifies consciousness reducing human complexity to a deterministic system. Biomachines that bypass time consuming conscious activity ultimately may be fielded by the DOD. The Defense Advanced Research Project Agency (DARPA) is already working towards this end. Through its Neurotechnology for Intelligence Analysts program, it has probed brain signals triggered when an analyst sees something interesting in a satellite image. The analyst's brain registers the discovery long before the analyst becomes cognitively aware of it. "The brain can signal the discovery three times faster than the analyst can respond... My goal is to use these technologies to harness the speed of thought... I know it's possible, especially if we confront these challenges not just as problems of biology and neuroscience but problems of physics, math, materials science and microtechnology....
