Worms gang up on bacteria

Proteins gang up on HIV

I t takes teamwork to defeat HIV, as Campbell et al. reveal. The researchers show that clusters of defensive proteins inside cells capture viral invaders and promote their destruction. Defensive TRIM5 proteins have a narrow but important job: fending off retroviruses that normally attack other species. Human versions trap certain mouse viruses, for example, and those from rhesus monkeys take on...

Evolution: A Turn Up for the Worms

Extensive sequencing of transcriptomes reveals the evolutionary relationships among the major flatworm lineages, suggesting new roots and conflicting routes to parasitism.

Lymphatic filariasis: inflammatory response to Wolbachia bacteria in filarial worms.

Bounds on Gang Service Scheduling

We deene the bounds of two gang service algorithms, namely time balanced and instruction balanced, using interactivity and throughput based metrics. The work-load is composed of V-RAM jobs, and the architectural model chosen is LogP. We also analyze the eeect of workload and space sharing strategies on the bounds found. The following results are demonstrated: when inter-activity is considered, ...

Worms, bacteria, and micronutrients: an elegant model of our diet.

Micronutrients are required in small proportions in a diet to carry out key metabolic roles for biomass and energy production. Humans receive micronutrients either directly from their diet or from gut microbiota that metabolize other nutrients. The nematode Caenorhabditis elegans and its bacterial diet provide a relatively simple and genetically tractable model to study both direct and microbe-...
