Due to low uptake of the MMR vaccine across the world, we have seen a dramatic rise in the number of cases of measles and mumps. These have gone against efforts to eradicate these diseases. Perceived safety concerns have led to the rise in uptake of single vaccines and thus for a number of years... Read More
Cells on the move reach forward with lamellipodia and filopodia, cytoplasmic sheets and rods supported by branched networks or tight bundles of actin filaments. Cells without functional lamellipodia are still highly motile but lose their ability to stay on track, report researchers at the Stower... Read More
Scientists of the Antwerp Institute of Tropical Medicine have breathed new life into a forgotten technique and so succeeded in detecting resistant tuberculosis in circumstances where so far this was hardly feasible. Tuberculosis bacilli that have become resistant against our major antibiotics ar... Read More
Do bacteria, like higher organisms, have a built-in program that tells them when to die? The process of apoptosis, or cell death, is an important part of normal animal development. In a new study published March 6 in the online, open-access journal PLoS Biology, Hanna Engelberg-Kulka and colleag... Read More
Community in the deep seabed uses so little oxygen that it is no longer clear where the lower bound for life lies.
Most humans would struggle to last for much more than a minute under water without coming up for air, whereas some seals can manage more than an hour — but a microbial community ... Read More
A scientific endeavour carried out by two French groups belonging to INSERM and CNRS at Aix-Marseilles University shows for the very first time that both bacterium adhesion to and bacterium motion on a surface are driven by the same mechanism (see paper in PNAS: "Wet-surface–enhanced ellipsometr...

Johnson & Johnson said Monday that it is seeking U.S. approval for the first new type of medicine to fight deadly tuberculosis in more than four decades.
The experimental drug, called bedaquiline, also would be the first medicine specifically for treating multi-drug-resistant tuberculosis. Th... Read More
A team of researchers led by scientists at Rockefeller University have discovered that a protein once thought to be mainly involved in antiviral immunity is in fact more important in fighting bacterial infections and could provide new mechanisms for treating diseases like tuberculosis, which is ...

In the first field study of its kind researchers at Royal Holloway, University of London and the University of Oxford have investigated the competitive dynamics of pathogenic and non-pathogenic strains of bacteria.
Bacteria are increasingly seen as living and interacting in groups and sharing... Read More
Signals from natural intestinal bacteria are necessary for an effective immune response to various viral or bacterial germs. This was the result of experiments by a research team led by Prof. Dr. Andreas Diefenbach and Stephanie Ganal at the Institute of Medical Microbiology and Hygiene of the F... Read More
Happy Fourth of July! In honor of this historic holiday we’ve compiled a list showing how infectious diseases and vaccines have affected the lives of our most heralded leaders – the American presidents. These concise accounts are evidence that diseases can strike anyone, anywhere at any time, an... Read More
At first glance it appears to be a minuscule marble spinning around its vertical axis. Look closer, however, and you see a stationary spherical membrane of fluid, just 3 microns across. It is the stuff inside the droplet that is rotating. This self-contained centrifuge has been created by blasti... Read More
Bloodstream infections caused by the MRSA superbug may be on the decline in communities across the U.S., according to a large study of military personnel.
Previous data from the Centers for Disease Control and Prevention show a drop in infections contracted in healthcare settings. But the tra... Read More
The first study using cultivation independent sequencing of the microorganisms in the adolescent male urinary tract has revealed that the composition of microbial communities colonizing the penis in young men depends upon their circumcision status and patterns of sexual activity.
This study, ... Read More
Ancient DNA of the bacteria causing syphilis, the Treponema pallidum pallidum, can be recovered from the ancient bones of newborns. This is the conclusion reached by a study led by Universitat Autònoma de Barcelona (UAB), which was able to obtain the genetic material from the bacteria in more th... Read More

Scientists studying loss of bone and muscle mass among astronauts find that spaceflight’s effects on microscopic worms may help them live longer.
The researchers discovered that spaceflight suppresses accumulation of toxic proteins that normally accumulate within aging muscle.
In addition,... Read More
Scientists at Johannes Gutenberg University Mainz (JGU) in Germany have discovered that tiny vanadium pentoxide nanoparticles can inhibit the growth of barnacles, bacteria, and algae on surfaces in contact with water, such as ship hulls, sea buoys, or offshore platforms. Their experiments showed... Read More
Studies suggest that infants who grow up with dogs in their home are less likely to develop asthma. Researchers may now have found one reason why. Pets, dogs in particular, may protect infants from the effects of a common virus, respiratory syncytial virus (RSV).
Infants with severe RSV infec... Read More
Prions are infectious prions which are responsible for often fatal neurological diseases in mammals but just how do they do this? What allows them to enter your body? How does it initially replicate itself? And how does it get into your brain? Research out last week in PLoS Pathogens shows that ... Read More
