Bioengineers at University of Pennsylvania devise nanoscale system to measure cellular forces
University of Pennsylvania researchers have designed a nanoscale system to observe and measure how individual cells react to external forces. view more (2007-08-28)
New model predicts damage to cheese
Researchers at a Dutch university have developed a model that predicts how cheese will change when a force is applied to it. This makes it possible to predict how cheese will be damaged during the packaging or transportation processes. Anna Rzepiela from Wageningen University simulated the influence of shearing and tensional forces on the... view more... (2003-04-11)
University of Arizona scientist shares in discovery of microbe filaments' power
Researchers from The University of Arizona and Columbia University have discovered that tiny filaments on bacteria can bundle together and pull with forces far stronger than experts had previously thought possible. view more (2008-04-21)
Protein simulation can be done three times as fast
Protein movement can be simulated three times as fast than had been thought possible up to now. Researchers from Groningen achieved the gain in speed by leaving out the calculations concerning hydrogen atoms. Meanwhile research groups around the world are adapting their simulation programs. view more (2002-06-24)
Research could help finger more criminals
Scientists at the University of Sunderland are working on new technology that could help police forces catch criminals, by providing more clear and detailed fingerprints. Researchers at the university's School of Health, Natural & Social Sciences are developing what's known as a nanoparticle suspension, which could be a major breakthrough for... view more...

Mathematical model gives clearer picture of physics of cells, organelles
Cells are filled with membrane-bound organelles like the nucleus, mitochondria and endoplasmic reticula. Over the years, scientists have made much progress in understanding the biomolecular details of how these organelles function within cells, but understanding the actual physical forces that maintain the structures of these organelles' membranes... view more...

Health And Politics: Lessons Learned From The Iraq Conflict (p 1371)
A Viewpoint in this week's issue of THE LANCET discusses the complex issues concerning the provision of humanitarian relief in the Iraq conflict. The authors of the article comment that 'the US armed forces have increased engagement in humanitarian projects, such as community health and food programmes. Relief organisations believe that this... view more... (2004-10-06)
Unraveling the physics of DNA's double helix
Researchers at Duke University's Pratt School of Engineering have uncovered a missing link in scientists' understanding of the physical forces that give DNA its famous double helix shape. view more (2007-07-13)
Media Invitation: Life, Science and Ethics - Press Conference, Glasgow, 20 July 2004
PRESS CONFERENCE Tuesday July 20, 11.30am at the SECC in Glasgow Stem cells, GM foods and human genetics are just a few examples of new science that is having a massive impact on the way we live. But where are the ethical boundaries? Progress at what cost? YOU ARE INVITED to a press conference on BIO-ETHICS, at which the UK's leading experts will... view more... (2004-07-16)
The Science Foresight Project
The Science Foresight Project is the first completely Internet-based international science foresight activity. The goal of the project was to identify emerging research developments in the physical and engineering sciences using experts selected by purely objective methods. The Science Foresight Project was a collaborative project between SPRU,... view more... (2002-08-26)
Small mechanical forces have big impact on embryonic stem cells
Applying a small mechanical force to embryonic stem cells could be a new way of coaxing them into a specific direction of differentiation, researchers at the University of Illinois report. Applications for force-directed cell differentiation include therapeutic cloning and regenerative medicine. view more (2009-10-19)
Researchers Make More Accurate Observation of Earth System Possible
Researchers at the Faculty of Aerospace Engineering of TU Delft have succeeded in modelling the rotational behaviour of two satellites with unprecedented accuracy. This makes it possible to model the orbit of the satellites much more accurately and this means that changes on earth observed by the satellite are also more accurate, for example,... view more...

Fuzziness on the road to physics' grand unification theory
Leave it to hypothesized gravity to weigh down what physicists have thought for 30 years. If theoretical physicists, led by the University of Oregon's Stephen Hsu, are right, the idea that nature's forces merge under grand unification has grown fuzzy. view more (2008-10-07)
Overstretched armed forces leading to mental health problems
Prolonged periods of deployment among Britain's armed forces is associated with mental health problems, finds a study published on bmj.com today. view more (2007-08-03)
NEW APPROACH TO STICKY PROBLEM
"Over the past 20 years people have been trying to develop techniques for studying structures of polymer surfaces to understand how these determine their adhesive performance," says Dr Leggett of the Manchester research team. "However, such surfaces are extremely difficult to study directly. They degrade very quickly under beams of... view more... (1999-11-04)
New study explains why hotter is better for insects
Organisms have been able to adapt to environments ranging from cold polar oceans to hot thermal vents. However, University of Washington researchers have discovered a limit to the powerful forces of natural selection, at least when it comes to the adaptation of insects to cold temperatures. view more (2006-10-03)
Slicing chromosomes leads to new insights into cell division
By using ultrafast laser pulses to slice off pieces of chromosomes and observe how the chromosomes behave, biomedical engineers at the University of Michigan have gained pivotal insights into mitosis, the process of cell division. view more (2009-06-01)
Protein folding: Diverse methods yield clues
Rice University physicists have written the next chapter in an innovative approach for studying the forces that shape proteins -- the biochemical workhorses of all living things. view more (2009-08-07)
Long distance runners at risk of low bone density
Long distance running increases the risk of low bone density, shows research in the British Journal of Sports Medicine. Accepted wisdom is that running, as a weight bearing exercise, increases bone density and therefore reduces the risk of osteoporosis and bone fracture. view more (2003-01-24)
Luminescence Dating, a new method of age determination
Physicists and geoscientists join forces in a Dutch research centre. Luminescence dating is a new technology for the determination of the age of sediments such as sand. At the Netherlands Centre for Luminescence Dating (NCL), physicists and geoscientists join forces to use and improve this new method. The foundation of the NCL will be celebrated... view more...
