Using Bacteria to Turn Sand Dunes into Architecture

Architecture student Magnus Larsson details his bold plan to transform the harsh Sahara desert using bacteria and a surprising construction material: the sand itself. Read More

Universal influenza vaccines

The need to re-formulate the influenza virus vaccine in response to viral antigenic drift and shift makes for complex logistics of vaccine production and administration. Surveillance programs must be conducted each year to identify strains that are likely to predominate and cause disease. Wouldn... Read More

Whooping cough predicted to double in 20 years, new vaccination strategies will be needed

A new paper in PLoS recommends two vaccination strategies to better prevent whooping cough.

"In the absence of adolescent or adult vaccination, pertussis incidence among adults is predicted to more than double in 20 years. Implementing an adult program in addition to childhood and adolescent... Read More

Viruses of protozoan parasites may exacerbate human disease

Many protozoan parasites (Trichomonas, Leishmania, Giardia, Plasmodium, Entamoeba, Nagleria, Eimeria, Cryptosporidium) are infected with viruses. These viruses do not infect vertebrates, but their double-stranded RNA genomes are sensed by the innate immune system, leading to inflammatory complic... Read More

Life at the Extreme

Many archaeans thrive in conditions that would kill other creatures: boiling water, super-salty pools, sulfur-spewing volcanic vents, acidic water and deep in Antarctic ice. These types of archaea are often labeled "extremophiles," meaning creatures that love extreme conditions.

Airway Microbiota and Pathogen Abundance in Age-Stratified Cystic Fibrosis Patients

Abstract - Bacterial communities in the airways of cystic fibrosis (CF) patients are, as in other ecological niches, influenced by autogenic and allogenic factors. However, our understanding of microbial colonization in younger versus older CF airways and the association with pulmonary function ... Read More

60 of the World's most memorable research papers

The Royal Society, founded in London in 1660 and one of the world's oldest scientific institutions, is marking the start of its 350th year by putting 60 of its most memorable research papers online.

Everyday Roles

Some people think it would be great if scientists could wipe out all the microbial bugs! Should we do it, and why or why not?


We get a lot of requests to track down the nasty bugs that are making people sick. It's true that some microbes cause health problems such as strep throat, chi... Read More

Inhibition of XMRV by a weapon of mass deamination

All mammalian genomes contain genes encoding Apobec proteins. Several members of this protein family (the name stands for apolipoprotein B mRNA editing complex) are induced by interferon and are intrinsic antiretroviral proteins. Apobec proteins inhibit the replication of XMRV, a new human retro... Read More

Are two tails better than one? A look at the Acidianus two-tailed virus

Merry Youle of Small Things Considered fame has a new post on the site that looks at the Acidianus two-tailed virus.

Snippet:

"Why two tails? Why such long tails? The researchers note that ATV is the only virus of an acidophilic hyperthermophile known to lyse its host, albeit only under st... Read More

TWiV 77
