SuperLigands - a database of ligand structures derived from the Protein Data Bank

...n treating patients. In addition, researchers must develop methods to efficiently direct the differentiation of embryonic stem cells to specific stable cell types. Scientists must also find a way to remove the remaining animal components from the laboratory procedures. Currently, the procedure for isolating ...

Microscopes at microscopic size

Important discovery about second most fatal cancer

...affected families have a genetic predisposition to develop DNA methylation. There is already evidence that su...cancer. Moreover, the colorectal cancers appear to develop in polyps that have been considered to be entirely harmless and have therefore been ignored up to no...

Nature provides inspiration for important new adhesive

...like a mussel-protein adhesive. Then they began to develop other strong and water-resistant wood adhesives from renewable natural materials using mussel protein as a model. The research work has resulted in 11 papers in journals such as Macromolecular Rapid Communications and the Journal of Adhesion Science ...

A new way to share models of biological systems

...s to address these issues." The first step was to develop a standard way of describing such models. The Systems Biology Markup Language (SBML), an open-source computer language developed by the SBML Team, is now widely accepted and is supported by over 75 different software systems worldwide. This allows co...

Making Sure Sacred Sheep Don't Become Extinct

...to consider social implications," he explains. To develop the collection, animal physiologist Phil Purdy, also of the Fort Collins center, traveled to the Navajo Nation to collect germplasm from rams owned by several Navajo sheep producers. Until Purdy developed relationships with various breeders, there wa...

Fox Chase study shows that weakened T-cell receptor signals change T-cell lineage

...l of versatility, creating a variety of cells that develop in different ways to protect the body. To carry out these tasks, immune cells follow a career path that forks at various points in their development. In a report in the May 2005 issue of Immunity, Fox Chase Cancer Center scientists led by immunologis...

Research into how prions act in the brain could hold the key to defeating diseases

...stroy. It is not known what causes the proteins to develop in this abnormal way and it is not known how they kill nerve cells in the brain. Professor Hugh Perry and colleagues of the University's School of Biological Sciences are examining exactly what makes particular nerve cells in the brain more susceptib...

Where bacteria get their genes

...e virulent. "To maintain effective treatments and develop new antibiotics, it's important to monitor the rates and patterns of lateral gene transfer," said team member Howard Ochman, a UA professor of biochemistry and molecular biophysics and a member of UA's BIO5 Institute. The research also solves a long...

NHGRI targets 12 more organisms for genome sequencing

...nimum set of genes that create a nervous system or develop a jaw, possibly illustrating how these systems have evolved in humans, and how they sometimes go wrong. Aplysia (Aplysia californica) is a sea slug that has been a very useful model in studying learning and memory in humans. Aplysia have very large ...

It will also help researchers looking into strokes and will enable them to understand the way the brain recovers in stroke patients. The scanner will also benefit researchers carrying out work int...

Human Eggs Can Develop From Ovarian Surface Cells In Vitro

...h has shown for the first time that human eggs may develop directly from cultured ovarian surface epithelium ...gs. However, definitive proof that new oocytes may develop in adult human females will be if they can be found to differentiate in vitro from OSE cells derived...

The research, which buttresses beliefs about the health benefits of green tea with solid scientific evidence, has been cited as part of the best doct...

Affymetrix and bioMerieux Extend Their Agreement on GeneChip(R) Technology to Breast Cancer Diagnostics

...prehensive access to its GeneChip(R) technology to develop and market in vitro diagnostic tests for breast cancer, as well as an option to expand the agreement into other cancer areas. The agreement, made under the Powered by Affymetrix(TM) program, gives bioMerieux non-exclusive rights to Affymetrix' paten...

Venom doc tracks down snake bioweapons

...al from other body tissues. This enabled snakes to develop more specific, highly potent toxins, ones that would cause their victims' bodies to turn against themselves upon injection. Over time, these newly derived toxins became a normal part of the saliva protein repertoire. To date, 24 different snake venom...

DOE JGI launches IMG public online microbial genome data clearinghouse
