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... view more (2005-07-18)

Genes involved in cell growth and cell division identified
A recent study shows that hundreds of genes contribute to cell growth and cell division. For the first time these genes, many of which are potential contributors to cancer, have been mapped in a single systematic study.   view more (2006-02-23)

Evolution study tightens human-chimp connection
Scientists at the Georgia Institute of Technology have found genetic evidence that seems to support a controversial hypothesis that humans and chimpanzees may be more closely related to each other than chimps are to the other two species of great apes - gorillas and orangutans.   view more (2006-01-24)

Diabetes complications rooted in faulty cell repair
University of Florida researchers say primitive cells that act like molecular maintenance men-traveling throughout the body to repair damaged blood vessels-become too rigid to move in patients with diabetes, fueling the disease's vascular complications.   view more (2006-01-26)

New microchip technology for medical imaging biomarkers of disease
A collaboration between scientists at UCLA, Caltech, Stanford, Siemens and Fluidigm have developed a new technology using integrated microfluidics chips for simplifying, lowering the cost and diversifying the types of molecules used to image the biology of disease with the medical imaging... view more (2005-12-16)

Feedback loop found that could forestall liver disease
Researchers at UT Southwestern Medical Center have discovered that the small intestine communicates with the liver to control the production of bile acids-a finding that has great medical implications in treating people at risk for certain types of liver disease.   view more (2005-10-12)

Genetically engineered blood protein can be used to split water into oxygen and hydrogen
Scientists have combined two molecules that occur naturally in blood to engineer a molecular complex that uses solar energy to split water into hydrogen and oxygen.   view more (2006-12-01)

Nanotubes inspire new technique for healing broken bones
Scientists have shown for the first time that carbon nanotubes make an ideal scaffold for the growth of bone tissue. The new technique could change the way doctors treat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing   view more (2005-07-11)

SLU Researchers Uncover Direct Evidence on How HIV Invades Healthy Cells
Using sophisticated detection methods, researchers at the Saint Louis University Institute for Molecular Virology (IMV) have demonstrated the molecular mechanism by which the HIV virus infects, or integrates, healthy cells. The discovery could lead to new drug treatments for HIV.   view more (2005-12-22)

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... view more (2006-04-04)

Scientists make first step towards 'holy grail' of crystallography
Scientists from Imperial College London and the University of Surrey have developed a new technique for crystallising proteins, a discovery which could help speed up the development of new medicines and treatments.   view more (2006-01-09)

Making alternative fuel becomes more efficient with dual-catalyst system: UNC-Rutgers study
As the United States' oil reserves dwindle, some say the nation will have to rely on synthetic petroleum fuel made from its large stores of coal.   view more (2006-04-14)

Scientists capture the speediest ever motion in a molecule
The fastest ever observations of protons moving within a molecule open a new window on fundamental processes in chemistry and biology, researchers report today in the journal Science.   view more (2006-03-03)

Second low-oxygen pathway hints at cancer, cardiovascular disease physiology
Researchers at the University of Pennsylvania School of Medicine have identified a second molecular pathway that promotes cell survival in low-oxygen conditions.   view more (2006-02-17)

Immune response to HIV in the brain
Using multi-disciplinary analysis that included cognitive, neurophysiologic, virologic, and molecular techniques, the team found both a low-level viral infection in the brain and immune cells that had infiltrated the brain in order to protect against the virus.   view more (2006-04-28)

Specific treatments for each type of sarcoma
The new molecular techniques allow designing specific treatments for a great number of sarcomas, according to Dr. Enrique de Alava, expert of the department of Pathologic Anatomy of the University Clinic of the University of Navarre. The molecular knowledge has become a very useful tool to study... view more (2002-11-29)

How butterflies got their spots: A 'supergene' controls wing pattern diversity
Butterflies are known to employ some interesting convergent evolutionary tactics to survive-some nonpoisonous species have similar wing patterns to those of noxious species that predators avoid.   view more (2006-09-26)

Research advances understanding of how hydrogen fuel is made
Oxygen may be necessary for life, but it sure gets in the way of making hydrogen fuel cheaply and abundantly from a family of enzymes present in many microorganisms.   view more (2005-10-06)

Long-term memory controlled by molecular pathway at synapses
Harvard University biologists have identified a molecular pathway active in neurons that interacts with RNA to regulate the formation of long-term memory in fruit flies.   view more (2006-01-13)

Marine bacterium suspected to play role in global carbon and nitrogen cycles
Scientists are now revisiting, and perhaps revising, their thinking about how Archaea, an ancient kingdom of single-celled microorganisms, are involved in maintaining the global balance of nitrogen and carbon.   view more (2005-09-23)

UCSD team unmasks family of immune system invaders
Like a family of petty criminals gone wrong, researchers at the University of California, San Diego (UCSD) were surprised to find that bacterial pathogens found in a number of troublesome diseases are actually related.   view more (2006-01-13)

Scientists' cell discovery unearths evolutionary clues
The full family tree of the species known as social amoebas has been plotted for the first time - a breakthrough which will provide important clues to the evolution of life on earth.   view more (2006-10-30)

Zeroing in on progeria: How mutant lamins cause premature aging
Children diagnosed with Hutchinson-Gilford Progeria Syndrome (HGPS) race through life against an unfairly fast clock. Cases are extremely rare-one in 8 million births-but time plays cruel tricks on HGPS newborns.   view more (2005-12-14)

Cancer cell communication exposed
The discovery, by scientists at Monash University and the Sloan Kettering Cancer Centre in New York, of how communication between cancer cells is controlled has promised new treatment options for malignant tumours.   view more (2005-10-31)

Major cancer study aims to identify protein markers for early-stage disease
A team led by Bay Area scientists is one of five nationwide to receive a major grant from the National Cancer Institute (NCI) to refine and standardize the technologies for identifying biomarkers in the blood - specific proteins, and the patterns they make - for the early detection of cancer.   view more (2006-09-29)
