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)
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)
Beyond genes: Lipid helps cell wall protein fold into proper shape
A protein that provides a vital passage through a bacterium's outer cell wall will misfold and malfunction if that wall is built of the 'wrong' material, scientists at The University of Texas Medical School at Houston report in a finding that has long-term implications for understanding diseases caused by misfolded proteins such as cystic... view more...

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)
Making nanoparticles in artificial cells
Two new construction manuals are now available for the world's smallest lamps. Based on these protocols, scientists from the Max Planck Institute of Colloids and Interfaces have tailor-made nanoparticles that can be used as position lights on cell proteins and, possibly in the future as well, as light sources for display screens or for optical... view more...

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)
New system of wastewater treatment could reduce the size of treatment plants by half
A group of researchers from the University of Granada (Universidad de Granada) have come up with a wastewater treatment system which has three clear advantages with respect to systems currently used: it is possible to obtain cheaper water of a higher quality, it considerably reduces the size of treatment plants (by more than half) and it minimizes... view more...

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)
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)
Could hormones explain gender differences in neurological disease?
Neurological diseases including Parkinson's, Tourette's, attention deficit hyperactivity disorder (ADHD), Alzheimer's, and schizophrenia are all associated with alterations in dopamine-driven function involving the dopamine transporter (DAT). view more (2009-06-16)
First structure of transporter enzyme family is solved - Finding will aid drug design to combat depression, stroke and diabetes
Scientists are a step closer to understanding how essential nutrients, vitamins and minerals are ferried into cells. For the first time, a member of the Major Facilitator Superfamily (MFS) of transport proteins, found in almost every form of life, has been visualised by researchers from Imperial College London and the University of California, Los... 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)
Discovery to aid study of biological structures, molecules
Researchers in the United States and Spain have discovered that a tool widely used in nanoscale imaging works differently in watery environments, a step toward better using the instrument to study biological molecules and structures. view more (2009-08-12)
Fusion in the fast lane
Using fast digital imaging, scientists from the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, together with researchers from Collîge de France, have succeeded in developing two different protocols by which one can initiate the fusion process in a controlled manner and observe the subsequent fusion dynamics with a... view more...

New Chlorine-Tolerant, Desalination Membrane Hopes to Boost Access to Clean Water
A chemical engineering professor at The University of Texas at Austin is part of a team that has developed a chlorine-tolerant membrane that should simplify the water desalination process, increasing access to fresh water and possibly reducing greenhouse gases. view more (2008-07-23)
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)
Orientation of antenna protein in photosynthetic bacteria described
Researchers at Washington University in St. Louis have figured out the orientation of a protein in the antenna complex to its neighboring membrane in a photosynthetic bacterium, a key find in the process of energy transfer in photosynthesis. view more (2009-04-03)
Technique used commonly in physics finds application in neuroscience
o understand how brain cells release compounds (or transmitters) used when the cells communicate with each other, Vladimir Parpura, associate professor of neuroscience, and Umar Mohideen, professor of physics at UC Riverside, devised a new technique, used commonly in physics, that can be applied now to the study of a wide range of biological... view more...

Scientists design simple dipstick test for cocaine, other drugs
Researchers at the University of Illinois at Urbana-Champaign have developed a simple "dipstick" test for detecting cocaine and other drugs in saliva, urine or blood serum. view more (2006-11-14)
Scientists shed light on the mystery of photosynthesis
Scientists at the University of Sheffield are part of an international team that has become the first to successfully discover how the component parts of photosynthesis fit together within the cell membrane. In a paper, The native architecture of a photosynthetic membrane, published in Nature on 26 August 2004, they describe how the configuration... view more... (2004-08-25)
