A balancing act between the sexes
Recent research at the European Molecular Biology Laboratory (EMBL) reveals new insights into how cells achieve equality between the sexes. view more (2006-03-17)
Abnormal proteins linked to schizophrenia found in body tissue
A new study suggests biochemical changes associated with schizophrenia aren't limited to the central nervous system and that the disease could have more encompassing effects throughout the body than previously thought. view more (2006-12-21)
Study shows frogs can play key role in stem cell research
It sounds like one of those curiosities which pops up in wildlife documentaries, but the African clawed frog could prove a powerful ally for scientists working in the key area of stem cell research. view more (2006-05-15)
Structural basis for photoswitching in fluorescent proteins brought into focus
University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours. view more (2007-04-11)
Simplicity is crucial to design optimization at nanoscale
MIT researchers who study the structure of protein-based materials with the aim of learning the key to their lightweight and robust strength have discovered that the particular arrangement of proteins that produces the sturdiest product is not the arrangement with the most built-in redundancy or the most complicated pattern. view more (2009-02-05)
Targeting helpers of heat shock proteins could help treat cancer, cardiovascular disease
Dissecting how heat shock protein 90 gets steroid receptors into shape to use hormones like estrogen and testosterone could lead to targeted therapies for hormone-driven cancers, such as breast and prostate, that need them as well, Medical College of Georgia researchers say. view more (2009-06-23)
Help for bleeding hearts: new research links a third protein to blood-clotting disorders
Studying receptors on the surface of blood platelets, sticky cells that cause blood to clot, has given one Rockefeller researcher new insight into potential causes and treatments for certain cardiovascular diseases. view more (2006-04-20)
Genomics reveals mechanism of heat resistance in bacteria
Warm-blooded creatures maintain a relatively stable body temperature that cannot tolerate the stress of intense heat (or cold). view more (2005-08-23)
Researchers characterize potential protein targets for malaria vaccine
Researchers from Nijmegen and Leiden have now characterized a large number of parasite proteins that may prove useful in the development of a human malaria vaccine. view more (2008-10-31)
Scientists learn to predict protein-stabilizing ability of small molecules
Researchers at the University of Texas Medical Branch at Galveston (UTMB) have developed a new way to predict the ability of certain small molecules to protect proteins in the cells of a wide variety of organisms living in extreme environments. view more (2005-10-10)
The Ethics of Patenting DNA and Proteins
Many companies and universities throughout the world are seeking to file patents on gene sequences and proteins. Questions remain, however, over the moral implications of protecting rights to property in this kind of way. The Nuffield Council on Bioethics is holding a series of Roundtable meetings to consider the ethical and legal issues raised by... view more... (2000-09-06)
Female Plant 'Communicates' Rejection or Acceptance of Male
Without eyes or ears, plants must rely on the interaction of molecules to determine appropriate mating partners and avoid inbreeding. view more (2008-10-24)
Two More Potential HIV Vaccines
Despite long-term researchers' efforts, efficient human immunodeficienct virus (HIV) vaccine has not been created yet. However, researchers are not giving up their attempts. Russian biologists are now proposing two more vaccine options based on DNA that encodes human immunodeficienct virus proteins. Experience proves that traditional ways of... view more... (2004-05-17)
New tests for nut allergens
Scientists in Florida have developed sensitive new tests to detect potentially fatal nut traces in food. Their study, published in the Journal of the Science of Food and Agriculture, originally set out to find ways of processing nuts to make them safe for allergy sufferers. The techniques they developed during the analysis included the discovery... view more... (2004-06-15)
Protein connections: A network to understand disease
In the 1990s, the notion of "six degrees of separation" emphasized human linkages that connected people around the world. view more (2006-05-19)
Molecular 'GPS' helps researchers probe processes important in aging and disease
With all the hype about beneficial antioxidants in everything from face cream to cereal bars, you'd think their targets-oxygen radicals-must be up to no good. view more (2009-09-04)
Spinal fluid proteins signal Lou Gehrig's disease
High levels of certain proteins in the spinal fluid could signal the onset of Lou Gehrig's disease, according to researchers. The discovery of these biomarkers may lead to diagnostic kits for early diagnosis, accurately measuring the progression of the disease and monitoring the effects of treatment. view more (2009-01-29)
Molecular typesetting -- proofreading without a proofreader
Researchers at the Universities of Leeds and Bristol (UK) have developed a model of how errors are corrected whilst proteins are being built. view more (2009-06-23)
FURTHER STEPS TOWARDS A VACCINE AGAINST HIV
For white blood cells in the human body to be infected by the HIV virus, proteins in the virus must be allowed to interact with a number of different components on the surface of the white blood cell. Ideally anti-HIV preventive therapy or vaccines would prevent several of these interactions taking place and would, therefore, reduce the likelihood... view more... (1999-03-11)
Sugar coupled to protein causes kidneys to save water
Several new mechanisms that are important for the production and transport of water channels to the cell surface of kidneys have been identified by a Dutch researcher. The water channels ensure that water in the body is reused. If these fail to work properly, you urinate too much and dehydrate. The research was a collaborative project between the... view more...
