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

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
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
Chronic pain is a very common health concern in all regions across the globe. Due to the ill effects of chronic pain, there has been an increase in the demand for pain management therapeutics. The global pain management therapeutics market offers many methods or therapies of pain management such... Read More

The TWiP triumvirate solves the case of the Missionary in Kenya, and review the finding of a soldier caste in flatworms that parasitize snails.
Whether you’ve Google-searched “biofilm” to learn more yourself, taken courses covering the subject, or are deeply embedded in biofilm-related research, you’ve probably encountered a model similar to the one below, which represents biofilm maturation. In the current model, a biofilm begins with ... Read More
Today it is well known that viruses may contain DNA (poxvirus, mimivirus) or RNA (influenza virus, Zika virus), but for many years it was thought that genomes were only made of DNA. The surprise at finding only RNA in a virus is plainly evident in a 1953 letter from Harriett Ephrussi-Taylor to J... Read More
Individuals with a psychiatric disorder involving recurrent bouts of extreme, impulsive anger--road rage, for example--are more than twice as likely to have been exposed to a common parasite than healthy individuals with no psychiatric diagnosis. Read More
New research indicates that curcumin--a substance in turmeric that is best known as one of the main components of curry powder--may help fight drug-resistant tuberculosis. In Asia, turmeric is used to treat many health conditions and it has anti-inflammatory, antioxidant, and perhaps even antica... Read More
