Plants respond similarly to signals from friends, enemies

...ant to harm the plant. Signals from both outsiders induce rapid changes in distribution of the plant's cytoskeleton, which is part of a pathway that leads to a series of growth changes that include the formation of either nodules housing bacteria or giant cells from which the nematodes feed.

Clam embryo study shows pollutant mixture adversely affects nerve cell development

...components tested,we found that all three together induce the greatest adverse response.Treating the embryos with the triple mixture resulted in increasedproduction of a subunit of an enzyme called protein kinase A (PKA),which previous research suggests plays a role in neural development,"says Reinisch.

Enzyme allows B cells to resist death, leading to leukemia

...al and treatment of malignantcells with drugs that induce cell death decreased both Lyn expressionlevels and activity ?suggesting a direct correlation between high Lynactivity and the ability of these B cells to resist apoptosis. Theauthors suggest that Lyn is involved in the development of B-CLL andthat th...

Spider Venom Could Yield Eco-Friendly Insecticides

... toxins can disrupt the insects?nervous systems or induce paralysis in just a few minutes. King and his colleagues are now developing both engineered viruses and small-molecule mimics of the toxins in preparation for field trials.

Duke Chemists Isolating Individual Molecules Of Toxic Protein In Alzheimer's, Parkinson's Disease

...orce at the atomic scale. Pulling back the tip can induce a measurable tug on the chemical bonds that hold together the two elevated monomers. By pulling on such bonds, the Duke scientists can deduce how much energy was required to bring the molecules together. Then, using their knowledge of protein chemis...

Antibodies from plants protect against anthrax
