Bacterial infection does not automatically lead to illness; many germs only become dangerous when they occur in large numbers. Researchers at the Max Planck Institute for Infection Biology in Berlin have discovered that the ...

(Phys.org)—Raising the temperature is one easy way to get chemical reactions to speed up. This temperature dependence can be accurately described by a simple exponential relation known as the Arrhenius equation. A commonly ...
(PhysOrg.com) -- Germs in food, bioterrorism, drug-resistant bacteria and viruses—these are the problems of our time that make early detection of pathogens particularly important. Whereas conventional methods are either ...

Early in mammalian embryonic development, long before the organism's ultimate form has taken shape, a precious subset of its cells are set aside for future use in creating offspring. This task bestows on that subset of cells ...

Ribosomal DNA (rDNA) sequences are essential parts of many species' genomes. The highly repetitive nature of these DNA sequences makes them susceptible to shrinkage over time—and if they shrink too much, cells die. If rDNA ...

Building on previous efforts to create a platform for the extended study of primate embryos in cell culture, two new reports from the State Key Laboratory of Primate Biomedical Research, Kunming University of Science and ...
Scientists have discovered that cells use a very simple phase transition -- similar to water vapor condensing into dew -- to assemble and localize subcellular structures that are involved in formation of the embryo.
