An international team of scientists from Singapore, Thailand, China and Australia has cracked the genetic code of the liver fluke parasite, Opisthorchis viverrini, using a unique DNA analysis technique developed at A*STAR’s Genome Institute of Singapore (GIS).
GIS’s DNA analysis technique ha... Read More
The Amazon river is the largest river in the world. It drains the entire Amazon rainforest, sending leftover nutrients, detritus, and minerals from the South American jungle out into the tropical Atlantic ocean. This runoff forms a freshwater plume, hundreds of miles across, that profoundly affe... Read More
Just in time for flu season, a new Michigan State University study of “the mother of all pandemics” could offer insight into infection control measures for the flu and other epidemic diseases.
Siddharth Chandra, director of MSU’s Asian Studies Center and professor in MSU’s James Madison Colle... Read More
In May 1984, readers of an article by Schwartz and Cantor in the prestigious journal Cell were to stumble upon pictures of DNA agarose gels that were among the lousiest of such ever published after the method was introduced in the early 70s. Why did the editors of Cell risk their reputation? Or ... Read More
A new study reveals that a protein of the Ebola virus can transform into three distinct shapes, each with a separate function that is critical to the virus's survival. Each shape offers a potential target for developing drugs against Ebola virus disease, a hemorrhagic fever that kills up to 9 ou... Read More
Recently identified cell-cycle controls are targets for new drugs that fight infections by shutting down division.
A cell is not a soap bubble that can simply pinch in two to reproduce. The ability to faithfully copy genetic material and distribute it equally to daughter cells is fundamental ... Read More
Researchers at UCL have developed a new antibacterial material which has potential for cutting hospital acquired infections. The combination of two simple dyes with nanoscopic particles of gold is deadly to bacteria when activated by light - even under modest indoor lighting. And in a first for ... Read More
A still somewhat unfamiliar term is floating around: the pan-genome. In 2005, Tettelin et al. coined the term along with genome analyses of eight Streptococcus agalactiae strains, and Merry introduced it to this blog, some time back already. Today, a keyword search in PubMed returns roughly 200 ... Read More
Johns Hopkins researchers have found evidence in mice that a tuberculosis (TB) infection in the lungs triggers immune system signaling to the gut that temporarily decreases the diversity of bacteria in that part of the digestive tract.
The Johns Hopkins researchers showed that this decrease i... Read More
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
Most of us are familiar with taking our daily probiotic supplement in the conventional way, either in capsule or powder form. It is however becoming increasingly apparent that people are discovering some weird and wonderful ways to use their probiotics, and here nutritional therapist Jo Saunders... Read More
The world of lipids does not always gets its due. Their oleaginous charm is not always appreciated, as we said here before. For example, have you heard of hopanoids? They are made by some bacteria and are an unusual kind of polycyclic lipids that resemble steroids, but with an extra ring. Just l... Read More
Gut bacteria in premature infants don't come from their mothers, but from microbes in the neonatal intensive-care unit (NICU), a new study finds. Babies typically get their gut bacteria from their mothers during childbirth. Premature infants, however, receive antibiotics during their first week ... 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
Fluoribacter bozemanae expressing blue-white fluorescence under long-wave UV light. If you look carefully one of the steaks does not fluoresce on the right hand side of the plate. The dark colony is actually Legionella pneumophila. Read More
Purdue University researchers have developed a laser sensor that can identify Salmonella bacteria grown from food samples about three times faster than conventional detection methods.
Known as BARDOT (pronounced bar-DOH'), the machine scans bacteria colonies and generates a distinct black and... Read More
Oman's first MERS coronavirus patient died in hospital on Sunday from lung failure, state news agency ONA said.
The Middle East Respiratory Syndrome Coronavirus (MERS-CoV), which can cause coughing, fever and pneumonia, emerged in Saudi Arabia last year and has been reported in Qatar, France,... Read More
Mineral coatings on sand particles actually encourage microbial activity in the rapid sand filters that are used to treat groundwater for drinking, according to a paper published ahead of print in Applied and Environmental Microbiology. These findings resoundingly refute, for the first time, the... Read More
As is our custom at this time of year, we go over the material that has appeared in this blog over the last six months. Seems like a lot of stuff, but it’s the result of the work of quite a number of dedicated people, all of whom deserve our gratitude.
