Latest Secretion Stories
Chuck Bednar for redOrbit.com - Your Universe Online Think helicopter parents take extreme measures to protect their offspring? Think again. Researchers from the University of Granada, along with along with colleagues from the Higher Council of Scientific Research (CSIC), have discovered the hoopoe (Upupa epops) coats its eggs with a bacterial secretion. The question was: Why, though? The study authors concluded that the secretion must provide some type of barrier to prevent...
Scientists may be able to entomb the malaria parasite in a prison of its own making.
A common plant puts out a welcome mat to bacteria seeking to invade, and scientists have discovered the mat's molecular mix.
Primary effusion lymphoma (PEL) is a rare B-cell neoplasm distinguished by its tendency to spread along the thin serous membranes that line body cavities without infiltrating or destroying nearby tissue.
Scientists at the Max Planck Institute for Chemical Ecology in Jena, Germany, have discovered the decisive biological stimulator for the accumulation of defensive substances in leaf beetle larvae used by the insects to fend off predators: ABC transport proteins, which are found in large quantities in glandular cells of the larvae.
Similar to passengers on an urban transit system, every protein made in the cell has a specific destination and function.
New research from Harvard University helps to explain how waterborne bacteria can colonize rough surfaces—even those that have been designed to resist water.
Bed bugs exchange specific chemical signals corresponding to particular behaviors, and researchers have now combined two unusual technologies to sniff out these signals in a matter of seconds.
Chemists at the California Institute of Technology (Caltech) have managed, for the first time, to simulate the biological function of a channel called the Sec translocon, which allows specific proteins to pass through membranes.
Agrobacterium tumefaciens is the causal agent of crown gall disease (the formation of tumours) in over 140 species of dicot. It is rod shaped. Symptoms are caused by the insertion of a small segment of DNA into the plant cell. It is an alphaproteobacterium of the family Rhizobiaceae which includes the nitrogen fixing legume symbionts. They are pathogenic and provide no benefit to the plant. It also affects a wide variety of plants. In an economical sense it affects walnuts, grape vines,...
