MIT-WHOI Graduate student Kristen Hunter-Cevera describes the challenges and obstacles involved with growing marine microbes (in her case, Synechococcus) in a laboratory setting, and outlines the value of her research in understanding marine biogeochemistry. Read More
Disease-causing viruses engage their hosts in ongoing arms races: positive selection for antiviral genes increases host fitness and survival, and viruses in turn select for mutations that counteract the antiviral host factors. Studying such adaptive mutations can provide insights into the distan... Read More

An international team of researchers has developed the largest genomic data set in the world on Lassa virus (LASV). The new genomic catalog contains nearly 200 viral genomes collected from patient samples in Sierra Leone and Nigeria, as well as field samples from the major animal reservoir, or h... Read More
Barbara Hinney and her colleagues from the Institute for Parasitology at the University of Veterinary Medicine, Vienna, screened 298 faecal samples taken from cats across Austria for single-cell intestinal parasites, so called enteric protozoa. The samples came from private households, catteries... Read More

TORONTO, Aug. 17, 2015--Promoting breastfeeding could lead to a substantial reduction in common infections and even deaths that are more common in Indigenous infants than non-Indigenous infants, a new study suggests. Read More
Three organisms inoculated in TSB to look at tube morphology. From left to right:
Staphylococcus aureus: flocculent growth/turbid, growth throughout the tube.
Mycobacterium smegmatis: pellicle, growth at the top of the tube. M. smegmatis tends to stick to the tube and grow up the side.
Ba... Read More
Carl Zimmer wondered if scientists had tattoos of their science and as it turns out, many do! Check out this great collection of science tattoos. I have to admit I browsed through the whole 23 page collection, fascinated by the art of science and seeing, in some cases, the full colored beauty of... Read More
I was at a tech meeting hosted by Amazon Web Services to see how I may use some of their cloud computing services for this site. One segment of the presentation was devoted to customers who use AWS for their sites or work. The slide you see in this image comes from Michael Schatz, Researcher at ... Read More
White-nose syndrome (WNS), an invasive skin infection caused by the Pseudogymnoascus destructans (Pd) fungus has killed millions of bats since it was first seen in North America in 2007. A analysis of gene expression in hibernating bats infected with the destructive fungus published on October 1... Read More
Torulopsis glabrata in kidney tubules of terminally ill patient. Patient died with another disease Read More
Plague infections were common in humans 3,300 years earlier than the historical record suggests, reports a study published October 22 in Cell. By sequencing the DNA of tooth samples from Bronze Age individuals from Europe and Asia, the researchers discovered evidence of plague infections roughly... Read More
Since it's 1st recorded outbreak (1976) in the Democratic Republic of the Congo's Ebola River Valley, the Ebola virus has been known - and feared - for good reason.
Why, you may ask?
Ebola hemorrhagic fever is potentially lethal and encompasses a range of symptoms including fever, vom... Read More

Among the bacterial infections that are most difficult to treat, chronic infections associated with bacterial biofilms are one of the most hazardous. Bacterial biofilms are densely packed communities of microbial cells surrounded with secreted polymers. In her doctoral thesis, chemist Shoghik Ha... Read More
