Near-universal T cell immunity towards a broad range of bacteria      (via sciencedaily.com)     Original source 

Typically T cells of the immune system respond to a specific feature (antigen) of a microbe, thereby generating protective immunity. Scientists have discovered an exception to this rule. Namely, a group of divergent bacterial pathogens, including pneumococci, all share a small highly conserved protein sequence, which is both presented and recognized by human T cells in a conserved population-wide manner.

Luring the virus into a trap      (via sciencedaily.com)     Original source 

Viruses like influenza A and Ebola invade human cells in a number of steps. Research teams investigated the final stages of viral penetration using electron tomography and computer simulations. So-called fusion pores, through which the viral genome is released into the host cell, play a central role in these processes. If they can be prevented from forming, the virus is also blocked. The Heidelberg scientists describe previously unknown mechanisms, which might lead to new approaches to prevent infections.

'BeerBots' could speed up the brewing process      (via sciencedaily.com)     Original source 

Craft brewers are continuously upping the ante and coming up with innovative ways to make or flavor their newest beers. Now, researchers are adding a new twist of their own, speeding up the brewing process with beer-making mini-robots or 'BeerBots.' The team shows that these self-propelled, magnetic packages of yeast can make the fermentation phase go faster and cut out the need to filter the beverage.
