H.P. Lovecraft fan and composer Reber Clark (https://reberclark.bandcamp.com/) collaborated with my undergraduate student Ruth Isenberg and myself on a science+music+HPL video. When a log phase culture of Photobacterium leignothi is poured into a Petri dish, and 10 second exposures are taken ev... Read More
This past fall, experts gathered at an American Academy of Microbiology Colloquium in Washington, D.C. to discuss an important topic relevant to many parts of society: the microbiology of built environments. A summary of the experts’ answers to important questions surrounding this topic is now a... Read More
CAMBRIDGE, MA -- MIT engineers have developed a new type of easily customizable vaccine that can be manufactured in one week, allowing it to be rapidly deployed in response to disease outbreaks. So far, they have designed vaccines against Ebola, H1N1 influenza, and Toxoplasma gondii (a relative ... Read More
As the durations of manned space missions increase, it is vitally important to understand the long-term consequences of microbial exposure on human health in closed human habitats. One mission of the Microbial Observatory Experiments on the International Space Station is to examine the traits an... Read More
Well you may ask what virus ?
and I tell you West Nile Virus ( but I want to change it to WNV ). Every year when mosquito season arrives it will bring a lot of diseases . one of them is the memory loss. you may ask how does memory loss concern WNV?
Thousands of people are liv... Read More
Releasing genetically modified mosquitoes appears to have helped reduce cases of dengue in a town in Brazil. The news comes as the US is considering whether to approve the use of the same mosquitoes.
The trial involved Aedes mosquitoes that had been modified to kill off wild mosquitoes of the... Read More
UConn medicinal chemists have developed experimental antibiotics that kill MRSA, a common and often deadly bacteria that causes skin, lung, and heart infections. The success is due to their strategy, which found a weakness and exploited it in a way the bacteria should have trouble countering, th... Read More
Scientists have genetically engineered bacteria to make a protein that squishes silicon and carbon together long enough for them to stick to one another — forming a bond that, until now, only chemists had managed to create. If scientists can teach these bacteria to produce the carbon-silicon mol... Read More
Vaccination with the anthrax capsule--a naturally occurring component of the bacterium that causes the disease--completely protected monkeys from lethal anthrax infection, according to a study published online this week in the journal VACCINE. These results indicate that anthrax capsule is a hig... Read More
With drug-resistant bacteria on the rise, scientists believe the nose is engaging in "microbial warfare". Scientists in Germany have identified that Staphylococcus lugdunensis, found in the nose, excretes a compound they named lugdunin. This compound prevents S. aureus from growing. S. aureus ca...

A newly discovered virus infecting the fungus that causes white-nose syndrome in bats could help scientists and wildlife agencies track the spread of the disease that is decimating bat populations in the United States, a new study suggests.
Regional variations in this virus could provide clue... Read More
Bacteria can communicate through a system known as quorum sensing, where, for example the production of toxin in some species is not initiated until a minimum threshold of bacterial cells are present. This allows them to coordinate and therefore strengthen their actions to overcome selective pre... Read More
Misdiagnosis can lead to severe consequences for patients, and is a serious clinical issue. The newly emerging Candida auris requires higher doses of antifungal medications to treat an infection than does C. albicans, highlighting the importance of proper diagnosis. Thus far, the most accurate d... Read More
Two studies, in the journal Cell, found a mutation increased the virus' ability to infect human cells fourfold.
Scientists have argued the mutation may have been "pivotal" in the outbreak becoming the largest in recorded history.
There were 28,616 Ebola cases in Guinea, Liberia and Sierra ... Read More
Just like you and me, bacteria have ‘favorite’ foods – though in the case of bacteria, 'favorite' translates to those which are energetically favorable or most accessible. Different bacteria have different preferences, based on their environments and the neighboring microbes that compete for or ... Read More
The anaerobic, Gram-positive Clostridium difficile is a big problem. It causes rampant diarrhea and tissue necrosis, with more than 150,000 annual cases in the United States alone. Many of the disease manifestations of C. difficile are mediated by two exotoxins that C. difficile produces: TcdA a... Read More
Chemosynthetic symbionts are bacteria living inside or on the surface of animals, supplying their host with food that would otherwise be unavailable. It has long been known that these bacteria fix carbon and convert it into organic forms. Microbiologist Jillian Petersen and colleagues from the U... Read More
Many years ago, Homo sapiens mated with Neanderthals. Today a small percentage of our genome remains Neanderthal, and in a study discussed on this episode of the science show This Week in Evolution, we show that some important genes of our innate immune response - the early response against path...

Cold viruses cause us irritation by penetrating into our cells and transporting their RNA into the cytoplasma of the infected cells. This is the only way they can multiply. The details of how the transfer of the RNA from within the virus occurs are difficult to study. However, a new method has b... Read More
Washington, DC – July 12, 2016 – Ebola and Marburg filovirus disease outbreaks have typically occurred as isolated events, confined to central Africa. However, the recent Ebola epidemic spread to several African countries, and caused 11,000 deaths. That epidemic underscored the need to develop v... Read More
