Plastic-Protein Hybrids
Functional membrane proteins in a block copolymer matrix Biological membranes form a fluid matrix, in which proteins "swim". Many of these membrane proteins are of interest for both pharmacological and biotechnological applications - for example, they are under consideration as biosensors for the rapid screening of pharmaceutical agents.... view more...

An atomic-level look at an HIV accomplice
Since the discovery in 2007 that a component of human semen called SEVI boosts infectivity of the virus that causes AIDS, researchers have been trying to learn more about SEVI and how it works, in hopes of thwarting its infection-promoting activity. view more (2009-11-20)
Texas A&M Researchers Examine How Viruses Destroy Bacteria
Viruses are well known for attacking humans and animals, but some viruses instead attack bacteria. Texas A&M University researchers are exploring how hungry viruses, armed with transformer-like weapons, attack bacteria, which may aid in the treatment of bacterial infections. view more (2009-11-19)
Sticky protein helps reinforce fragile muscle membranes
A new study by scientists at the University of Iowa shows why muscle membranes don't rupture when healthy people exercise. view more (2009-07-24)
Researchers discover how malaria parasite disperses from red blood cells
Researchers at the National Institute of Child Health and Human Development have determined the sequence in which the malaria parasite disperses from the red blood cells it infects. view more (2005-09-20)
Location matters, even for genes
Moving an active gene from the interior of the nucleus to its periphery can inactivate that gene report scientists from the University of Chicago Medical Center in an article to be published early online Feb.13, 2008, in the journal Nature. view more (2008-02-14)
Forecasting Heart Storms
The requirements of man to the weather forecast are changing before our eyes. Before, a temperature, precipitation and wind forecast could do, while now man want to know the condition of the electromagnetic field of the Earth in a month ahead, desirably. Those, who suffer from heart diseases, are the ones to worry most of all: cardio-vascular... view more... (2002-04-02)
Tracking membranes of rupturing blood cells sheds light on malaria infection
By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria pathogen destroys the cells in which it resides. view more (2005-09-22)
Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily
Carnegie Mellon University scientists have made an important discovery that aids the understanding of why HIV enters immune cells with ease. view more (2007-07-26)
One membrane, many frequencies
Modern hearing aids, though quite sophisticated, still do not faithfully reproduce sound as hearing people perceive it. New findings at the Weizmann Institute of Science shed light on a crucial mechanism for discerning different sound frequencies and thus may have implications for the design of better hearing aids. view more (2007-03-28)
Structural mechanism of the E. coli drug efflux pump AcrB
In a new study published online in the open access journal PLoS Biology, Gaby Sennhauser, Marcus Gruetter, and colleagues use structural biology techniques to probe the molecular mechanisms of the major drug efflux pump in E. coli AcrB. view more (2006-12-27)
Asymmetry due to Perfect Balance
Cell membranes are like two-dimensional fluids whose molecules are distributed evenly through lateral diffusion. But many important cellular processes depend on cortical polarity, the locally elevated concentration of specific membrane proteins. view more (2007-04-26)
Century-old rule of chemistry overturned -- major implications for drug delivery
A new study by research chemists at the University of Warwick has challenged a century old rule of pharmacology that defined how quickly key chemicals can pass across cell walls. view more (2008-08-26)
Imbalance may trigger advance from fatty liver to liver failure
An imbalance in the lipid content of the liver appears to trigger the downward spiral that leads some with fatty liver disease to advance to full-blown liver failure, according to a new study in the May Cell Metabolism. view more (2006-05-10)
Uncovering the Achilles' heel of the HIV-1 envelope
New structural details illustrate how a promising class of antibodies may block human immunodeficiency virus (HIV)-1 infection and reveal valuable clues for design of an effective HIV-1 vaccine. view more (2008-01-14)
Researchers describe how cells take out the trash to prevent disease
Garbage collectors are important for removing trash; without them waste accumulates and can quickly become a health hazard. Similarly, individual cells that make up such biological organisms as humans also have sophisticated methods for managing waste. view more (2008-11-11)
Bacteria reveal secret of adaptation at Evolution Canyon
Bacteria living on opposite sides of a canyon have evolved to cope with different temperatures by altering the make-up of their 'skin', or cell membranes. Scientists have found that bacteria change these complex and important structures to adapt to different temperatures by looking at the appearance of the bacteria as well as their genes. view more (2008-07-28)
Carnegie Mellon develops computer model to study cell membrane dynamics
A cell constantly remodels its fluid membranes to carry out critical tasks, such as recognizing other cells, getting nutrients or sorting proteins. view more (2008-04-09)
New, more direct pathways from outside the cell-to-cell nuclei discovered
A team of Brooklyn College researchers has shattered a long-held belief that no direct pathway exists between material outside of a cell and the cell nucleus. (The cell is the smallest metabolically functional unit of life.) view more (2007-08-13)
Human immunodeficiency virus (HIV) treatment
Russian researchers have developed a medication capable of protecting against various human immunodeficiency virus (HIV) strains. Their effort has been supported by the International Scientific Technical Center. Intense search for efficacious human immunodeficiency virus treatment carried out by scientific laboratories worldwide has not yet... view more... (2004-01-30)
