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)
Bioengineers develop a microfabricated device to measure cellular forces during tissue development
A University of Pennsylvania-collaboration of bioengineers studying the physical forces generated by individual cells has created a tiny micron-sized device that allows researchers to measure and manipulate cellular forces as assemblies of living cells reorganize themselves into tissues. view more (2009-06-23)
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)
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)
Elastic interactions of membrane proteins
Cellular survival relies crucially on the ability to receive and communicate signals from and to the outside world. A major part of this regulation and communication is performed by proteins within the membrane of a cell. view more (2007-05-04)
Nanosecond-scale release of stinging jellyfish nematocysts
By using an electronic ultra-high-speed camera, researchers have characterized the explosive discharge of stinging jellyfish nematocytes and show that this event represents one of the fastest cellular processes in nature. view more (2006-05-09)
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...

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)
University of Minnesota researchers take new look at cellular suicide
Like a bodyguard turned traitor, a protein whose regular job is to help repair severed DNA molecules will, in some cases, join forces with another protein to do the opposite and chop the DNA to bits. view more (2006-07-07)
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)
Researchers identify proteins making up mechanosensitive ion channels
Researchers at Washington University in St. Louis are the first to identify two proteins responsible for mechanosensitive ion channel activities in plant roots. Scientists have long known that plant cells respond to physical forces. Until now, however, the proteins controlling the ion channel response remained a mystery. view more (2008-06-03)
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)
Stretching bone marrow stem cells pushes them towards becoming blood vessel
When stretched, a type of adult stem cell taken from bone marrow can be nudged towards becoming the type of tissue found in blood vessels, according to a new study by bioengineers at the University of California, Berkeley. view more (2006-10-24)
New epidemiological review finds no causal association between the use of cellular phones and cancer
The Swedish Radiation Protection Authority has engaged two internationally well-known epidemiologists to review published epidemiological studies on the relationship between the use of cellular telephones and cancer risk. They are Dr. John D. Boice, Jr. and Dr. Joseph K. McLaughlin from the International Epidemiology Institute, USA. In their... view more... (2002-09-20)
Key protein in cellular respiration discovered
Many diseases derive from problems with cellular respiration, the process through which cells extract energy from nutrients. Researchers at Karolinska Institutet have now discovered a new function for a protein in the mitochondrion - popularly called the cell's power station - that plays a key part in cell respiration. view more (2009-04-08)
