The researchers propose that the molecular motor contributes to restructuring the extracellular support matrix during tissue growth and development or wound repair or even during cancerous invasion of tissues.

They observed that the synergistic effect of high levels of calcium intake and vigorous (as opposed to moderate or low-intensity) activity were the most effective in building and ret...Researchers devise potent new tools to curb ivory poaching

Such non-invasive techniques can be used to quickly assemble genetic reference maps to apply this technology to other at-risk species.

Working with seven leading laboratories in Europe, the researchers will plant and study Arabidopsis at six diverse sites, ranging from subarctic locales in Finland -- which at times during the year have jus......ectroporation. This technology allowed the team to track cells that had been electroporated with the mutant forms of Cdc42 and observe as they contributed to somite formation. Electroporation of dominant negative and constitutively active forms of Rac1 also indicated a role for that molecule in the mesenc...Snakehead in your inbox?

Now, users can report nonindigenous and invasive aquatic species they sight, automatically receive email alerts, or perform searches on aquatic species -- such as American alligators in Pennsylvania, Asian c...Second call for proposals for the European Young Investigator Award

Researchers found green cells throughout the body, but observed that the highest concentration of bone marrow cells was in normal skin. That was a surprise.

...ithin the islets. Until recently, the only way to track type 1 diabetes in its earliest stages was to measure blood levels of autoantibodies (the immune system's "guided missiles") directed against pancreatic islet proteins. Yet, these tests are only an indirect indication of the disease process, and don'...Molecular motor myosin VI moves 'hand over hand,' researchers say
...anometer Accuracy -- the measurement technique can track the position of a single molecule to within 1.5 nanometers. (One nanometer is a billionth of a meter, or about 10,000 times smaller than the width of a human hair).

...Environmental engineers are seeking better ways to track these emerging pollutants, which tend to be more complex and water-soluble than previous contaminants of concern, such as chlorinated solvents and petroleum byproducts. This new modeling approach is important because environmental regulators and clea...Tiny molecules have big potential as cancer drugs, Stanford researcher believes
...out, Bogyo and colleagues used fluorescent tags to track cathepsin activity in mouse models of two types of cancer. They found the cathepsins helped build blood vessels to the tumors as well as increase tumor growth and invasiveness. The team also tried giving a broad-spectrum cathepsin inhibitor to some c...Carnegie Mellon scientists reveal ways of studying, resolving PCB contamination in US rivers
