| News media losing role as gatekeepers to new 'social mediators' on Twitter Posted: 05 Sep 2014 06:08 AM PDT The US government is doing a better job of communicating on Twitter with people in sensitive areas like the Middle East and North Africa without the participation of media organizations, according to a study.       |
| Ultra sensitive biosensor from molybdenite semiconductor developed Posted: 05 Sep 2014 06:08 AM PDT Researchers have demonstrated an atomically thin, ultrasensitive and scalable molybdenum disulfide field-effect transistor based biosensors and establish their potential for single-molecule detection.  |
| Magnetic nanocubes self-assemble into helical superstructures Posted: 04 Sep 2014 03:36 PM PDT Nanochemists have found that magnetite nanocubes can self-assemble into helical superstructures under certain conditions; theoretical chemists simulated the phenomenon and explained the conditions under which it can occur.  |
| Artificial cells take their first steps: Movable cytoskeleton membrane fabricated for first time Posted: 04 Sep 2014 11:19 AM PDT Using only a few ingredients, a biophysicist and his team have successfully implemented a minimalistic model of the cell that can change its shape and move on its own. They describe how they turned this goal into reality in a new article.  |
| Posted: 04 Sep 2014 08:12 AM PDT Scientists have published an experimental study of ignition of jet fuel. They have described how quickly a mixture of jet fuel and oxygen ignites depending on different conditions.  |
| Guideline for determining effectiveness of college football training methods Posted: 03 Sep 2014 01:36 PM PDT Athletic performance varies from day to day, which can make it difficult for strength and conditioning professionals to judge whether athletes' improvements are due to effective training. Now, researchers have established a guideline that trainers can use to distinguish whether college football players' improvements on weightlifting tests result from increased performance capability or day-to-day variability.  |
| Tweets during 2013 Colorado floods gave engineers valuable data on infrastructure damage Posted: 03 Sep 2014 10:33 AM PDT Tweets sent during last year's massive flooding on Colorado's Front Range were able to detail the scope of damage to the area's infrastructure, according to a study. The findings can help geotechnical and structural engineers more effectively direct their reconnaissance efforts after future natural disasters -- including earthquakes, tsunamis and tornadoes -- as well as provide them data that might otherwise be lost due to rapid cleanup efforts.  |
| Isn't it time that UK family doctors embraced email services for their patients? Posted: 02 Sep 2014 05:53 PM PDT E-mail services are either more convenient for patients and make better use of clinicians' time, or make more work for already hard pressed health-care professionals and threaten patient safety, argue two doctors.  |
| Microphysiological systems will revolutionize experimental biology, medicine, experts say Posted: 02 Sep 2014 12:12 PM PDT Microphysiological Systems Program (MPS) as in vitro models for bone/cartilage, brain, gastrointestinal tract, lung, liver, microvasculature, reproductive tract, skeletal muscle, and skin, are addressed in a new paper, including the interconnection of MPS to support physiologically based pharmacokinetics and drug discovery and screening, and the microscale technologies that regulate stem cell differentiation.  |
| New nano-sized synthetic scaffolding technique revealed Posted: 02 Sep 2014 12:12 PM PDT Scientists have tapped oil and water to create scaffolds of self-assembling, synthetic proteins called peptoid nanosheets that mimic complex biological mechanisms and processes.  |
| New program to evaluate prominent individuals' personalities Posted: 02 Sep 2014 12:11 PM PDT A new program has been developed that automates classification of personality traits of prominent individuals -- both friend and foe. The new computer-supported methodology for personality profiling uses "vector semantics." This involves constructing a number of vectors representing personality dimensions and disorders and measuring the similarity with texts written by the human subject.  |
