Scientists identify proteins that help bacteria put up a fight
Scientists have identified the role of two proteins that contribute to disease-causing bacteria cells' versatility in resisting certain classes of antibiotics.   view more (2008-02-26)

Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development
o ignite a life-threatening infection in the body, a virus such as HIV invades body cells by first merging, or fusing, with the cell's outer membrane. Once inside the cell, the invading microbe's genetic material takes over, turning the 'host' cell into a factory to produce more copies of the virus, which then spill out to invade other cells in... view more...

Cell 'anchors' required to prevent muscular dystrophy
A protein that was first identified for playing a key role in regulating normal heart rhythms also appears to be significant in helping muscle cells survive the forces of muscle contraction. The clue was a laboratory mouse that seemed to have a form of muscular dystrophy.   view more (2009-01-14)

Key event in cell death occurs as single, quick event
Scientists at St. Jude Children's Research Hospital have demonstrated that a key event during apoptosis (cell suicide) occurs as a single, quick event, rather than as a step-by-step process.   view more (2006-08-02)

Scientists reveal fine detail of cell`s energy machinery
A molecular pump that helps to keep cells flush with energy has been visualised by scientists at Imperial College, London. The structure of the pump, a key enzyme in bacterial respiration, reveals for the first time one of the molecular mechanisms that underpins cellular respiration, and confirms a Nobel Prize-winning theory proposed over 40... view more...

Smart thin film membranes adopt properties of guest molecules
Virginia Tech researchers announced last year that they had created a nanostructured membrane that incorporates DNA base pairs in order to impart molecular recognition and binding ability to the synthetic material.   view more (2007-03-29)

Synchrotron radiation illuminates how babies' protective bubble bursts
Researchers at the University of Reading, School of Pharmacy have developed an important new technique to study one of the most common causes of premature birth and prenatal mortality.   view more (2007-11-07)

Chemical Could Revolutionize Polymer Fuel Cells
Heat has always been a problem for fuel cells. There's usually either too much (ceramic fuel cells) for certain portable uses, such as automobiles or electronics, or too little (polymer fuel cells) to be efficient.   view more (2005-08-25)

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...

Saltwater solution to save crops
Technology under development at the University of New South Wales could offer new hope to farmers in drought-affected and marginal areas by enabling crops to grow using salty groundwater.   view more (2008-09-12)

Hoping for a fluorescent basket case
Although recent advances have raised hopes that a protective vaccine can be developed, acquired immunodeficiency syndrome (AIDS) remains a major public health problem.   view more (2009-11-13)

A new understanding of how cells defend themselves against bacterial pore-forming toxins
Biologists at the EPFL (Ecole Polytechnique Federale de Lausanne) have unveiled a new twist in a metabolic pathway that cells use to defend themselves against toxins made by disease-causing bacteria.   view more (2006-09-22)

Hepatitis C virus channels efforts into cell survival
Researchers at the University of Leeds have discovered a previously unknown mechanism that allows the hepatitis C virus (HCV) to remain in the body for decades.   view more (2009-08-18)

pHLIP, a novel technology to locate and treat tumors
Research teams at Yale University and the University of Rhode Island have demonstrated a new way to target and potentially treat tumors using a short piece of protein that acts like a nanosyringe to deliver "tags" or therapy to cells, according to a report in the Proceedings of the National Academy of Sciences.   view more (2007-05-02)

Scientists decipher mechanism behind antimicrobial 'hole punchers'
In the battle against bacteria, researchers have scored a direct hit. They have made a discovery that could shorten the road to new and more potent antibiotics.   view more (2007-09-21)

NJIT professor discovers better way to desalinate water
Chemical engineer Kamalesh Sirkar, PhD, a distinguished professor at New Jersey Institute of Technology (NJIT) and an expert in membrane separation technology, is leading a team of researchers to develop a breakthrough method to desalinate water.   view more (2006-02-10)

Nanoreactors for Reaction Cascades
Living cells are highly complex synthetic machines: Numerous multistep reactions run simultaneously side by side and with unbelievable efficiency and specificity. For these mainly enzymatic reactions to work so well collectively, nature makes use of a variety of concepts.   view more (2007-08-21)

Matrix protein key to fighting viruses
Researchers from Durham University's Centre for Bioactive Chemistry are developing methods that show how proteins interact with cell membranes when a virus strikes.   view more (2009-04-29)

Nixing immaturity in red blood cells
A process of self-digestion called autophagy prompts the maturation of red blood cells. Without a protein called Nix, the cells would not effectively rid themselves of organelles called mitochondria and consequently become short-lived, leading to anemia, said researchers at Baylor College of Medicine in Houston in a report that appears online... view more...

Rac 1 and 2, two proteins essential to triggering of the immune response
The dendritic cells act as the body's sentries, standing guard around the clock. As soon as they detect a potential enemy, they alert the T cells, whose role is to defend the body. At the Institut Curie, CNRS researchers in an Inserm laboratory have filmed the encounter of dendritic cells and T cells. They have shown that this "rendez-vous",... view more... (2004-08-23)
