Insulin regulates the secretion of the antiaging hormome Klotho
Dr. Carmela Abraham, a professor of biochemistry and medicine at Boston University School of Medicine (BUSM), reports this week in the Proceedings of the National Academy of Sciences new findings on Klotho, an anti-aging gene that is associated with life span extension in rodents and humans. view more (2007-11-28)
Carnegie Mellon researcher proposes development of artificial cells to fight disease
Carnegie Mellon University's Philip LeDuc predicts the use of artificially created cells could be a potential new therapeutic approach for treating diseases in an ever-changing world. view more (2007-02-08)
New Tissueflex System Makes Artificial Liver Cell Cultivation an Attractive and Viable Option
The drug development process from the discovery of an optimised lead then on to market is typically a seven to ten year process. It is well known to be an expensive process with a high risk of failure as recent high profile cases have shown. But even after extensive clinical trials new drugs can prove to be ineffective or at worst dangerous to... view more... (2004-11-19)
How an enzyme tells stem cells which way to divide
Driving Miranda, a protein in fruit flies crucial to switch a stem cell's fate, is not as complex as biologists thought, according to University of Oregon biochemists. They've found that one enzyme (aPKC) stands alone and acts as a traffic cop that directs which roads daughter cells will take. view more (2009-05-14)
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...

New discoveries about neuron plasticity linked to learning and memory
Neurons experience large-scale changes across their dendrites during learning, say neuroscientists at The University of Texas at Austin in a new study that highlights the important role that these cell regions may play in the processes of learning and memory. view more (2005-11-02)
BGSU biologist trying to crack microscopic code
The Bowling Green State University biologist wants to crack the communication code of proteins, especially the ones whose "talking" aids and abets disease. view more (2006-08-23)
University of Pittsburgh researchers crack code of 3-D structure in key metabolic protein
Using X-ray crystallography, researchers at the University of Pittsburgh School of Medicine led by structural biologist Joanne I. Yeh, Ph.D., have become the first to decipher the three-dimensional structure of a membrane-bound enzyme that plays a crucial role in glycerol metabolism - a discovery that could lead to important advances against... view more...

Fuel Cells, Energy Conversion, and Mathematics
Concerns about dwindling fossil fuel resources, current levels of petroleum consumption, and growing pressure to shift to more sustainable energy sources are among the many factors prompting the transition from our current energy infrastructure to one that uses less carbon and requires the efficient conversion of energy. view more (2009-07-27)
St. Jude researchers find key step in programmed cell death
Investigators at St. Jude Children's Research Hospital have discovered a dance of proteins that protects certain cells from undergoing apoptosis, also known as programmed cell death. Understanding the fine points of apoptosis is important to researchers seeking ways to control this process. view more (2008-03-03)
Research identifies 3-D structure of key nuclear pore building block
The genome of complex organisms is stashed away inside each cell's nucleus, a little like a sovereign shielded from the threatening world outside. view more (2009-06-08)
£4 Million for New Centres for Structural Biology
The Biotechnology and Biological Sciences Research Council (BBSRC) today announces its intention to fund four more UK Centres for Structural Biology. view more (1999-02-01)
A step forward in virology
The vaccinia virus has a problem: it is a giant among viruses and needs a special strategy in order to infiltrate a cell and reproduce. view more (2008-04-25)
How sperm crack the whip
Researchers have identified a key component of the mechanism spermatozoa use to abruptly convert their tail motion from a steady swimming undulation to the whip-cracking snap that thrusts them into an egg. view more (2006-02-09)
Physics and biology team up to tackle protein folding debate
A team of researchers from EPFL, (Ecole Polytechnique Fédérale de Lausanne), the University of Lausanne, Northwestern University and Tel Aviv University bring biology and statistical physics together to answer the question of how molecular chaperones fold, unfold and pull proteins around in the cell. view more (2006-04-04)
Distinguishing single cells with nothing but light
Researchers at the University of Rochester have developed a novel optical technique that permits rapid analysis of single human immune cells using only light. view more (2009-04-01)
Two-faced protein can stop metastasis or promote it, researchers say
A protein known to be a key component of the glue that holds cells together also is involved in breaking them apart and promoting their movement when tumors begin to spread to other parts of the body, researchers at Mayo Clinic have found. view more (2006-09-19)
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)
Super-thin Filter, 50 Atoms Thick, Sorts Individual Molecules
A newly designed porous membrane, so thin it's invisible edge-on, may revolutionize the way doctors and scientists manipulate objects as small as a molecule. view more (2007-02-15)
Purdue researchers obtain a snapshot clarifying how materials enter cells
A group of Purdue University researchers has captured a key step in the metabolic process that allows materials, such as nutrients and drug treatments, to move in and out of cells. view more (2007-12-03)
