Animal genomes are known to contain captured retroviruses, typically referred to as endogenous retroviruses (ERVs). Many of these elements are still transcribed and are known to be involved in both beneficial functions in animal biology, such as placenta formation, and not-so beneficial functio... Read More
There are bacteria in wine that may be beneficial for people's health, new research finds.
In the study, researchers in Spain isolated 11 strains of bacteria from wine, including strains of Lactobacillus, which are also found in yogurt, as well as Oenococcus and Pediococcus bacteria, which ar... Read More
Twenty-six species of Cryptosporidium have been recognised and 18 species declared non-valid in a recent shake-up of the parasite's taxonomy using DNA sequencing techniques.
Cryptosporidium is the second biggest cause of infant diarrhoea and death in developing countries, and is found across ... Read More
Bacillus anthracis bacteria have very efficient machinery for injecting toxic proteins into cells, leading to the potentially deadly infection known as anthrax. A team of MIT researchers has now hijacked that delivery system for a different purpose: administering cancer drugs.
“Anthrax toxin ... Read More
Dangerous new pathogens such as the Ebola virus invoke scary scenarios of deadly epidemics, but even ancient scourges such as the bubonic plague are still providing researchers with new insights on how the body responds to infections.
In a study published online Sept. 18, 2014, in the journal... Read More
Any research institution that receives federal funding will soon have to screen certain kinds of scientific experiments to see if the work could potentially be misused to endanger the public.
The new policy will take effect next year, and it's the latest effort by the U. S. government to come... Read More

Could Ebola go airborne? That’s the fear set off last week by a New York Times op-ed entitled “What We’re Afraid to Say about Ebola” from Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota. Although clinicians readily agree that th... Read More
Influenza infection can enhance the ability of the bacterium Streptococcus pneumoniae to cause ear and throat infections, according to research published ahead of print in the journal Infection and Immunity.
In the study, the investigators infected mice with either influenza alone, pneumococc... Read More
A Virginia Tech geobiologist with collaborators from the Chinese Academy of Sciences have found evidence in the fossil record that complex multicellularity appeared in living things about 600 million years ago – nearly 60 million years before skeletal animals appeared during a huge growth spurt ...

A pesar de los beneficios que suponen las vacunas, muchas personas desconocen cómo funcionan e incluso desconfían de su acción. Las vacunas siempre son más seguras que la propia enfermedad de la que protegen. Algunas enfermedades infecciosas no tienen un tratamiento efectivo y las vacunas son la... Read More
The same viruses that make us sick can take up residence in and on the human body without provoking a sneeze, cough or other troublesome symptom, according to new research. On average, healthy individuals carry about five types of viruses on their bodies, the researchers report. The study is the... Read More
Pregnant women have an unusually strong immune response to influenza, an unexpected finding that may explain why they get sicker from the flu than other healthy adults, new research from the Stanford University School of Medicine and Lucile Packard Children's Hospital Stanford has found.
The ... Read More
The traditional light microscope is bulky and expensive. Dr Tri Phan and Dr Steve Lee from the Garvan Institute of Medical Research and Australian National University used gravity to manufacture high-performance polymer lenses. These can be seamlessly integrated with 3D printing and mini-LEDs to... Read More
The TWiV team consults an epidemiologist to forecast the future scope of the Ebola virus epidemic in West Africa.
A mathematical model that replicates Ebola outbreaks can no longer be used to ascertain the eventual scale of the current epidemic, finds research conducted by the University of Warwick.
Dr Thomas House, of the University’s Warwick Mathematics Institute, developed a model that incorporated da... Read More
McMaster scientists have found that an anticonvulsant drug may help in developing a new class of antibiotics.
Although dozens of antibiotics target what bacteria do, their study has looked at how a certain part of bacteria are created, and they found there is a way of stopping it.
The disc... Read More
(A) Bacillus subtilis, (B) Staphlococcus aureus and (C) Escherichia coli were grown on BHI media with varying concentrations of NaCl (0.85%, 5%, 7.5%, 10%, and 20%) at 37 degrees C for 24 hrs. Read More
(A) Staphlococcus aureus, (B) Bacillus stearothermophilus, (C) Pseudomonas fluorescens and (D) Escherichia coli were grown on TSA for 24 hrs at varying incubator temperatures (4, 25, 40, and 60 degree’s C). Note: The 4 degree plate were incubated for a week to get good Pseudomonas fluorescens ... Read More
Brazilian researchers in Rio de Janeiro have released thousands of mosquitoes infected with bacteria that suppress dengue fever.
The hope is they will multiply, breed and become the majority of mosquitoes, thus reducing cases of the disease.
The initiative is part of a programme also takin... Read More
