Scientists trace molecular origin of proportional development
When it comes to embryo formation in the lowly fruit fly, a little molecular messiness actually leads to enhanced developmental precision, according to a study in the Oct. 14 Developmental Cell from Cincinnati Children's Hospital Medical Center.   view more (2008-10-14)

Embryonic heart exhibits impressive regenerative capacity
A new study demonstrates that the embryonic mouse heart has an astounding capacity to regenerate, a phenomenon previously observed only in non-mammalian species.   view more (2008-10-14)

Response to immune protein determines pathology of multiple sclerosis
New research may help reveal why different parts of the brain can come under attack in patients with multiple sclerosis (MS). According to a new study in mice with an MS-like disease, the brain's response to a protein produced by invading T cells dictates whether it's the spinal cord or cerebellum... view more (2008-10-14)

Forsyth scientists trigger cancer-like response from embryonic stem cells
Scientists from The Forsyth Institute, working with collaborators at Tufts and Tuebingen Universities, have discovered a new control over embryonic stem cells' behavior.   view more (2008-10-14)

On the trail of a targeted therapy for blood cancers
nvestigators from the Herman B Wells Center for Pediatric Research at the Indiana University School of Medicine are focusing on a family of blood proteins that they hope holds a key to decreasing the toxic effects of chemotherapy in children and adults.   view more (2008-10-13)

Yamanaka eliminates viral vector in stem cell reprogramming
Shinya Yamanaka MD, PhD, of Kyoto University and the Gladstone Institute of Cardiovascular Disease (GICD) has taken another step forward in improving the possibilities for the practical application of induced pluripotent stem (iPS) cell technology.   view more (2008-10-13)

A link between mitochondria and tumor formation in stem cells
Researchers report on a previously unknown relationship between stem cell potency and the metabolic rate of their mitochondria -a cell's energy makers. Stem cells with more active mitochondria also have a greater capacity to differentiate and are more likely to form tumors.   view more (2008-10-13)

Landmark study unlocks stem cell, DNA secrets to speed therapies
In a groundbreaking study led by an eminent molecular biologist at Florida State University, researchers have discovered that as embryonic stem cells turn into different cell types, there are dramatic corresponding changes to the order in which DNA is replicated and reorganized.   view more (2008-10-13)

Digital zebrafish embryo provides the first complete developmental blueprint of a vertebrate
Researchers at the European Molecular Biology Laboratory (EMBL) have generated a digital zebrafish embryo - the first complete developmental blueprint of a vertebrate. With a newly developed microscope scientists could for the first time track all cells for the first 24 hours in the life of a... view more (2008-10-10)

Keeping herpes infection in check: Pitt researchers describe immune system strategies
Herpes simplex virus type I can cause bouts of cold sores, blindness and potentially lethal encephalitis when it reawakens from a quiescent state in the nerve cells it infects.   view more (2008-10-10)

Hodgkin lymphoma -- new characteristics discovered
Researchers are still discovering new characteristics of Hodgkin lymphoma, a common form of cancer of the lymphatic system. The malignant cells are derived from white blood cells (B cells), but have lost a considerable part of the B cell-specific gene expression pattern.    view more (2008-10-09)

Fat injections can improve breast reconstruction -- jury's out on augmentation
Injecting fat after breast reconstruction to correct implant wrinkling or dimpling may be safe and effective to improve breast shape.   view more (2008-10-09)

Researchers design artificial cells that could power medical implants
Researchers at Yale University have created a blueprint for artificial cells that are more powerful and efficient than the natural cells they mimic and could one day be used to power tiny medical implants.   view more (2008-10-09)

Rong Li Lab probes mechanism of asymmetry in meiotic cell division
The Stowers Institute's Rong Li Lab has characterized a mechanism that allows for asymmetrical cell division during meiosis in oocytes. By tracking chromosome movement in live mouse oocytes, the team discovered that chromosomes can recruit to their vicinity a protein called formin-2.   view more (2008-10-08)

Burnham Researchers Turn Cancer Friend into Cancer Foe
Burnham Institute for Medical Research today announced that scientists have created a peptide that binds to Bcl-2, a protein that protects cancer cells from programmed cell death, and converts it into a cancer cell killer.   view more (2008-10-08)

Egg whites solve the 3-D problem
The real world is three-dimensional. That's true even in the laboratory, where scientists have to grow cells to study how they develop and what happens when their growth is abnormal.   view more (2008-10-08)

Researchers discover that SLC2A9 is a high-capacity urate transporter in humans
An international team of researchers led by Professors Mark Caulfield and Patricia Munroe, from the William Harvey Research Institute at Barts and The London School of Medicine and Dentistry with Chris Cheeseman at the University of Alberta in Canada and Kelle Moley at the University of Washington... view more (2008-10-07)

Surface tension drives segregation within cell mixtures
What does a mixture of two different kinds of cells have in common with a mixture of oil and water? The same basic force causes both mixtures to separate into two distinct regions.   view more (2008-10-07)

Mayo researchers explore issues related to multiple myeloma treatment
Multiple myeloma (MM) is a cancer of plasma cells that affects approximately 3 in 100,000 people each year. Although there is no cure for this disease, researchers have developed treatments that help relieve pain, control complications, and slow the progress of MM in many patients.   view more (2008-10-07)

Discovery of natural compounds that could slow blood vessel growth
Using computer models and live cell experiments, biomedical engineers at the Johns Hopkins University School of Medicine have discovered more than 100 human protein fragments that can slow or stop the growth of cells that make up new blood vessels.   view more (2008-10-06)

Newly identified cells make fat
To understand where fat comes from, you have to start with a skinny mouse. By using such a creature, and observing the growth of fat after injections of different kinds of immature cells, scientists at the Howard Hughes Medical Institute and Rockefeller University have discovered an important fat... view more (2008-10-06)

Metastatic movements in 3-D
Caswell et al.report in the Journal of Cell Biology how the altered behavior of integrins can prompt metastatic movement in tumor cells.    view more (2008-10-06)

DNA of good bacteria drives intestinal response to infection
A new study shows that the DNA of so-called "good bacteria" that normally live in the intestines may help defend the body against infection.   view more (2008-10-03)

Structures of Important Plant Viruses Determined
Flexible filamentous viruses make up a large fraction of known plant viruses and are responsible for more than half the viral damage to crop plants throughout the world.   view more (2008-10-02)

When cells go bad
When a cell's chromosomes lose their ends, the cell usually kills itself to stem the genetic damage. But University of Utah biologists discovered how those cells can evade suicide and start down the path to cancer.   view more (2008-10-01)
