In bacterial mitosis, DNA passes through the DNA polymerase, rather than the polymerase walking along the chromosome. BioMedNet May 25 New research shows how the deadly Ebola virus overwhelms the immune system and kills its victims within a week. But, the studies have also revealed a possible Achilles heel that could be used quickly to counter a viral attack. Planetary scientists are struggling to come up with a definition of life that includes both us and the organisms that may, or may not, exist beyond Earth. May 25 Yogurt, made with a particular strain of Lactobacillus could provide an alternative to antibiotics in treating Helicobacter pylori infection, the bacterium responsible for gastric and peptic ulcers.
Mold can kill, but establishing a causal link is hard.
In the meantime we should reduce condensation in our homes. To avoid having their hideouts discovered and destroyed, viruses co-opt a variety of immune molecules for their own purposes. Modern molecular tools are enabling researchers to take a closer look at our evolutionary history. In the latest development, the sequencing of the Giardia genome has stirred up heated debate about the divergence of the prokaryotes and the eukaryotes. Taking advantage of this trait, researchers are developing effective vaccines against the viruses by rearranging the order of the viral genes.
