How Bacteria Sense Salt Stress

Scientists' finding is a major breakthrough in understanding a decades-old problem of how bacteria detect environmental changes.

A team of scientists led by Assistant Professor Ganesh S Anand and Professor Linda J. Kenney from the National University of Singapore (NUS) Department of Biologica... Read More

When dying, bacteria share some characteristics with higher organisms

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

Slo-mo microbes extend the frontiers of life

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 novel imaging technique sheds new light on bacterial mobility and adhesion

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...

J&J seeks OK for first drug against resistant TB

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

Scientists reveal how natural systems limit the spread of "cheating" bacteria

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

Deadly Bat Fungus in Missouri, Farthest West Yet

A disease that has killed millions of bats across multiple states and Canada has been found in Missouri, marking its advent west of the Mississippi River and spelling possible trouble for agriculture in the region, officials said Monday.

White nose syndrome has been confirmed in three bats in... Read More

Protein proves to be vital in immune response to bacteria

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 ...

Innate immune system protein provides a new target in war against bacterial infections

Research led by St. Jude Children’s Research Hospital scientists has identified a possible new approach to defeating bacterial infections by targeting an innate immune system component in a bid to invigorate the immune response.

In this study, researchers demonstrated that the primary functio... Read More

Natural Intestinal Flora Strengthens Immune System

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

Fourth of July: American Presidents and Infectious Diseases

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

Parasite of the Day: Xenopsylla ramesis

There is no parasite that is universally infective, even generalist parasites that can infect many different host species are usually limited to a particular taxonomic group - such as fish, insects, or mammals. Some parasites may infect a broad spectrum of hosts during one stage of their life-cy... Read More

Superbug infections dropping across US, army finds

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

What a sound idea

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

Time in space may stretch worm lifespan

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

Inspired by nature: Paints and coatings containing bactericidal agent nanoparticles combat marine fouling

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
