How bacteria adhere to cells: Basis for the development of a new class of antibiotics
GOETHE UNIVERSITY FRANKFURT FRANKFURT. The adhesion of bacteria to host cells is always the first and one of the decisive steps in the development of infectious diseases. The purpose of this adhesion by infectious pathogens is first to colonize the host organism (i.e., the human body), and then to trigger an infection, which in the...

Researchers uncover new pathway for accumulation of age-promoting ‘zombie cells’
UNIVERSITY OF PITTSBURGH IMAGE: X-SHAPED CHROMOSOMES ARE STAINED PURPLE, AND TELOMERES APPEAR AS GREEN SPOTS AT CHROMOSOME TIPS. WHEN RESEARCHERS USED A NOVEL TOOL TO INDUCE OXIDATIVE DAMAGE SPECIFICALLY AT TELOMERES, THEY CAN BECOME FRAGILE (GREEN ARROWS), SENDING CELLS INTO SENESCENCE. THE INSET SHOWS AN ENLARGED CHROMOSOME WITH FRAGILE TELOMERES, INDICATED BY MULTIPLE GREEN SPOTS...

Some viruses make you smell tastier to mosquitoes
UNIVERSITY OF CONNECTICUT Zika and dengue fever viruses alter the scent of mice and humans they infect, researchers report in the 30 June issue of Cell. The altered scent attracts mosquitoes, which bite the host, drink their infected blood and then carry the virus to its next victim. Dengue is spread by mosquitoes in tropical areas...
