June 25, 2009 A Trio of Signals Converge to Induce Liver and Pancreas Cell Development in the Embryo
Understanding the molecular signals that guide early cells in the embryo to develop into different organs provides insight into ways that tissues regenerate and how stem cells can be used for new therapies. view more (2009-06-29)
Site for alcohol's action in the brain discovered
lcohol's inebriating effects are familiar to everyone. But the molecular details of alcohol's impact on brain activity remain a mystery. view more (2009-06-29)
Natural-born divers and the molecular traces of evolution
An aquatic lifestyle imposes serious demands for the organism, and this is true even for the tiniest molecules that form our body. view more (2009-06-29)
How mitochondria get their membranes bent
Mitochondria are the powerhouses of cells. Underneath their smooth surface they harbor an elaborately folded inner membrane. It holds a multitude of bottleneck like invaginations, which expand into elongated cavities (cristae). view more (2009-06-25)
Anti-inflammatory drugs may defeat a treatment-resistant type of cancer
Effective drugs for treating a chemotherapy-resistant form of lymphoma might already be on the market according to a study that has pieced together a chemical pathway involved in the disease. view more (2009-06-25)
Midget plant gets makeover
A tiny plant with a long name (Arabidopsis thaliana) helps researchers from over 120 countries learn how to design new crops to help meet increasing demands for food, biofuels, industrial materials, and new medicines. view more (2009-06-23)
BRIT1 allows DNA repair teams access to damaged sites
Like a mechanic popping the hood of a car to get at a faulty engine, a tumor-suppressing protein allows cellular repair mechanisms to pounce on damaged DNA by overcoming a barrier to DNA access. view more (2009-06-22)
Discovery of the cell's water gate may lead to new cancer drugs
The flow of water into and out from the cell may play a crucial role in several types of cancer. Scientists at the University of Gothenburg have now found the gate that regulates the flow of water into yeast cells. view more (2009-06-17)
New study reveals structure of the HIV protein shell
New research by scientists at The Scripps Research Institute and other institutions provides a close-up look at the cone-shaped shell that is the hallmark of human immunodeficiency virus (HIV), revealing how it is held together-and possible ways to break it apart. view more (2009-06-15)
Embryology Study Offers Clues to Birth Defects
Gregg Duester, Ph.D., professor of developmental biology at Burnham Institute for Medical Research (Burnham), along with Xianling Zhao, Ph.D., and colleagues, have clarified the role that retinoic acid plays in limb development. view more (2009-06-10)
Cancer: The cost of being smarter than chimps?
Are the cognitively superior brains of humans, in part, responsible for our higher rates of cancer? That's a question that has nagged at John McDonald, chair of Georgia Tech's School of Biology and chief research scientist at the Ovarian Cancer Institute, for a while. view more (2009-06-10)
Rutgers Research Tackles Childhood Epilepsy
Rutgers researchers have discovered a potential new way to treat childhood epilepsy using a widely available therapeutic drug. view more (2009-06-10)
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)
Scientists explain how 'death receptors' designed to kill our cells may make them stronger
It turns out that from the perspective of cell biology, Nietzsche may have been right after all: that which does not kill us does make us stronger. view more (2009-06-02)
Researchers identify gene that regulates tumors in neuroblastoma
Virginia Commonwealth University researchers have identified a gene that may play a key role in regulating tumor progression in neuroblastoma, a form of cancer usually found in young children. view more (2009-06-02)
New 3-D structural model of critical H1N1 protein developed
In just two weeks from the time the first patient virus samples were made available, Singapore scientists report an evolutionary analysis of a critical protein produced by the 2009 H1N1 influenza A virus strain. view more (2009-05-26)
Back to basics: Scientists discover a fundamental mechanism for cell organization
Scientists have discovered that cells use a very simple phase transition -- similar to water vapor condensing into dew -- to assemble and localize subcellular structures that are involved in formation of the embryo. view more (2009-05-22)
Why the thumb of the right hand is on the left hand side
It is the concentration of a few signaling molecules that determines the fate of individual cells during the early development of organisms. view more (2009-05-22)
Research reveals molecular pathway behind invasive prostate cancers
University of Cincinnati (UC) cancer and cell biologists have identified a new molecular pathway key to the development of invasive prostate cancers. view more (2009-05-19)
Biological Timekeeper Studies Reveal New Temperature Regulator and Track Clock Protein across a Day
Dartmouth Medical School geneticists have made new inroads into understanding the regulatory circuitry of the biological clock that synchronizes the ebb and flow of daily activities. view more (2009-05-18)
