Bacteria are the most abundant form of life on Earth, and they are capable of living in diverse habitats ranging from the surface of rocks to the insides of our intestines. Over millennia, these adaptable little organisms have evolved a variety of specialized mechanisms to move themselves throug... Read More
Scientists at the The University of Queensland and the University of California San Francisco have found a new way to inhibit the growth of the bacterium that causes tuberculosis (TB). Read More
Boston, MA - The parasite responsible for a form of malaria now spreading from macaques to humans in South Asia could evolve to infect humans more efficiently, a step towards enhanced transmission between humans, according to a new study from Harvard T.H. Chan School of Public Health. The resear... Read More
The genomes of two distinct strains of the virus that causes the common lip cold sore, herpes simplex virus type 1 (HSV-1), have been identified within an individual person -- an achievement that could be useful to forensic scientists for tracing a person's history. The research also opens the d... Read More
How do we define the genetic makeup of an individual? Is it the genetic material found in each cell of that individual (that’s not entirely accurate; mutations and recombinatorial differences can lead to multiple genomes in one individual). And what about the genes carried by our microbiome? The... Read More
Labyrinthulids or commonly known as Slime nets are group of protists of the Class Labyrinthulomycota. These organisms form tube-like structures or filaments (forming a complex net) that serve as tracks where cells glide. They are commonly isolated from seagrass and fallen senescent mangrove lea...

If the DNA sequence of a cell is like the operating system of a computer, then the smallest cellular OS has just been written. Called Syn3.0, it encodes everything needed to make a viable, autonomously replicating cell.
Mycoplasma is a genus of bacteria that are the smallest known free-living... Read More
Zika's hypothesized attraction to human neural stem cells may come from its ability to hijack a protein found on the surface of these cells, using it as an entryway to infection. In Cell Stem Cell on March 30, researchers at the University of California, San Francisco show that the AXL surface r... Read More
A near-atomic level map of Zika virus shows its structure to be largely similar to that of dengue virus and other flaviviruses, but with a notable difference in one key surface protein, report scientists funded by the National Institute of Allergy and Infectious Diseases (NIAID), part of the Nat...

Escherichia coli (E.coli) is a Gram negative rod-shaped bacteria commonly found in intestines of warm blooded animals. Majority of the E.coli strains are harmless, however certain strains are known to cause serious medical complications.The rising number of supportive initiatives from government... Read More
Scientists and science educators now recognize the value in explaining what fields don’t understand, in addition to facts supported by years of experimental data. Citizen science projects, which emphasize accessibility of scientific technologies and methods for everyone, allow people without yea... Read More
Viruses have proven to be wily foes. Attempts to fend off viruses that cause the common cold or flu have failed, and new viral outbreaks such as dengue, Ebola, or Zika continue to elude drugs.
Given these challenges, scientists are tackling the problem from a different angle. The want to boos... Read More
CORVALLIS, Ore. - A new analysis of the prehistoric origin of malaria suggests that it evolved in insects at least 100 million years ago, and the first vertebrate hosts of this disease were probably reptiles, which at that time would have included the dinosaurs. Read More
I have had chronic nasal congestion for my whole life. Sometimes it is worse, sometimes it is better, but it is never completely gone. I have seen ENT specialists and have only ever been told that it must be allergies. I have never believed this, and so I have finally taken matters into my own h... Read More
Like many other virologists we have also begun to work on Zika virus, to apply our expertise and knowledge to this emerging pathogen. Here is a photo of some of the vials of Zika virus that we have recently obtained. Shown are the MR766 and DAK AR 41542 strains and plasma from a Zika virus infec... Read More
Several weeks ago we perfected a plaque assay for Zika virus, based on our existing assays for enteroviruses. Shown is a photograph of two plates stained with crystal virolet with clearly delineated plaques. The cells are Vero and the Zika virus strain is MR766, an African isolate. Anyone intere... Read More
This is the air sample from the area nearby our school gym collected using Burkard portable for agar plate. Sample was collected in environmental and occupational health class of public health student at Taipei Medical University, Taipei, Taiwan. Sampler was operate at 20 liters/min with MEA pla...

Fecal transplants are increasingly being used for refractory Clostridium difficile and other gastrointestinal disorders. While fecal donors are screened for various infectious diseases, it is unclear whether viruses can in fact be transmitted during fecal transplants. Now a new study shows that ... Read More
