Students in the summer STEM program at Cabrillo (these were college age students) were asked to do a handprint of their unwashed hand then of their hand after washing. This is a before and after of what the majority of the plates looked like. Plates were incubated for 48 hrs at 37 degrees C ... Read More
The campaign is called "Kick Back Ebola." But the posters pack a punch.
Sierra Leone has reported over 700 suspected Ebola cases, more than any other country this year. To help stop the outbreak, health workers have put up Ebola awareness signs all over Sierra Leone's seaside capital of Freet... Read More
Scientists at the National Institutes of Health (NIH) have created a protein that awakens resting immune cells infected with HIV and facilitates their destruction in laboratory studies. The protein potentially could contribute to a cure for HIV infection by helping deplete the reservoir of long-... Read More
Athens, Ga. - Lax state vaccination laws contribute to lower immunization rates and increased outbreaks of preventable diseases--like whooping cough and measles--according to a new study from the University of Georgia. 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
For the first time in more than a year, Guinea passed a week without a new lab-confirmed Ebola case, but the news out of West Africa last week was tempered by a flare-up of activity in Sierra Leone, the World Health Organization (WHO) reported today in its latest update. Read More
This strain of Pseudomonas aeruginosa isolated from wound make a green pigment: pyoverdine. Pyoverdine is a fluorescent siderophores for to acquire iron.
Pyoverdine biosynthesis in Pseudomonas aeruginosa and fluorescent Pseudomonads is a complex process.

BOSTON, Aug. 18, 2015 -- When a fever strikes in a developing area, the immediate concern may be: Is it the common flu or something much worse that requires quarantine? To facilitate diagnosis in remote, low-resource settings, researchers have developed a paper-based device that changes color, d... Read More
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
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
Just when we think we know everything, a story comes along to remind us that there is something fundamental--and seemingly elementary--that we still haven't figured out. “Why are we the size we are? Why are our organs the size they are? Why are the cells in those organs a stereotypical size? Wha... Read More
There is currently no approved specific treatment or vaccine for dengue fever, and an estimated 2 billion people are at risk for being bitten by Aedes mosquitoes and infected with the dengue virus (DENV). A study published on October 22nd in PLOS Pathogens introduces a candidate target for a tra... Read More
Four intracellular Toxoplasma gondii parasites are shown undergoing cellular division by an internal budding process known as endodyogeny. Staining with a T. gondii surface antigen provided heart-shaped images (shot on Valentine’s Day). The definitive host of these parasites is the cat, but they... Read More
Colonies are initially black and yeast-like, becoming suede-like, olivaceous grey and mould-like with age. This photo show the morphology of colony after a week.

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
Leaves of the European chestnut tree contain ingredients with the power to disarm dangerous staph bacteria without boosting its drug resistance, scientists have found. Read More
Scientific experiments with the herpesvirus such as the one that causes Marek's disease in poultry have confirmed, for the first time, the highly controversial theory that some vaccines could allow more-virulent versions of a virus to survive, putting unvaccinated individuals at greater risk of ...

This cutely radish photo of the colony of Aspergillus niger was taken by a digital camera. Before that Aspergillus niger was grown on SDA (Saboraud Dextrose Agar) media for the research purpose of testing antifungal activity of Scallop Powder(SP). SP ,a natural source obtained from Bivalves, can... Read More
Influenza is known as an infectious respiratory disease, but a study published on October 8th in PLOS Pathogens suggests that infected cells in breast tissues could play a role in virus transmission from mothers to breast-feeding infants and vice versa using a ferret model. Read More
