New research demonstrates that novel probe technology based on flexible membranes can replace conventional atomic force microscopy (AFM) cantilevers for applications such as fast topographic imaging, quantitative material characterization and single molecule mechanics measurements.
In addition to the standard AFM topography scan, these novel probes simultaneously measure material properties including adhesion, stiffness, elasticity and viscosity.
Incorporating health and safety concepts into building plans reduces accident rates and safety costs, according to the PhD defended by engineer Juan Pedro Reyes at the University of the Basque Country
Athens, Ga. Television news audiences are divided along party lines like never before, according to a new University of Georgia study that warns the trend may have damaging consequences for political discourse and democracy in America.
Ideology and partisanship used to be completely unrelated to the television news people consumed, said study author Barry Hollander, associate professor of journalism in the UGA Grady College of Journalism and Mass Communication. But theyve become significant factors in the last five years.
JACKSONVILLE, Fla. Two new international studies by researchers at the Mayo Clinic site in Florida are rounding out the notion that Parkinsons disease is largely caused by inherited genetic mutations that pass through scores of related generations over hundreds, if not thousands of years. These genetic influences, which can be small but additive, or large and causative, overturn common beliefs that the neurodegenerative disease mostly occurs in a random fashion or is due to undetermined environmental factors.
The worlds oldest recorded tree is a 9,550 year old spruce in the Dalarna province of Sweden.
The spruce tree has shown to be a tenacious survivor that has endured by growing between erect trees and smaller bushes in pace with the dramatic climate changes over time.
For many years the spruce tree has been regarded as a relative newcomer in the Swedish mountain region.
Washington, DC — Without clear leadership and more transparency in federal risk research investment, the emergence of safe nanotechnologies will be a happy accident, rather than a foregone conclusion, says Dr. Andrew Maynard, the Chief Science Advisor for the Project on Emerging Nanotechnologies (PEN). This sentiment was voiced today by Dr. Maynard in testimony at the House Science & Technology Committees hearing on the National Nanotechnology Initiative Amendments Act of 2008.
A computer system that can carry on a discussion with a human being by reacting to signals such as tone of voice and facial expression, is being developed by an international team including Queens University Belfast.
Known as SEMAINE, the project will build a Sensitive Artificial Listener (SAL) system, which will perceive a human users facial expression, gaze, and voice and then engage with the user. When engaging with a human, the SAL will be able to adapt its own performance and pursue different actions, depending on the non-verbal behaviour of the user.
People who score high on intelligence tests are also good at keeping time, new Swedish research shows. The team that carried out the study also suspect that accuracy in timing is important to the brain processes responsible for problem solving and reasoning.
The International Osteoporosis Foundation (IOF) has urged all 27 EU countries to continue to seek government recognition and action to overcome the growing burden that osteoporosis places on health systems throughout Europe, as work continues on the second report to measure the status of osteoporosis management across member states.
