NTU scientists discover potential vaccine for malaria

Scientists from Singapore’s Nanyang Technological University (NTU) have discovered a key process during the invasion of the blood cell by the Malaria parasite, and more importantly, found a way to block this invasion.

With this new knowledge, NTU is looking to collaborate with the industry on... Read More

Dr. Roy Curtiss, Biodesign Institute, "Turning a Foe into a Friend"

This video submission for the ASM Global Video Challenge highlights the impact of Salmonella-based vaccines on human health. Read More

Does medicine really need lab mice?

Using animals to test drugs destined for humans is controversial, with critics arguing there are other ways to ensure new medicines are safe and effective. But the scientists who carry out the research say animal studies remain necessary.

It is estimated that in the UK around three million mi... Read More

"Touchy" Bacteria Grow Tendrils Around Flaws

A common soil-dwelling microbe appears to have a sense of touch, researchers report.

A new study finds that Bacillus mycoides, a bacterium known to science since 1842, responds to forces and curvature in the medium on which it’s growing.

The microbe’s ability to respond to subtle changes i... Read More

Luminous bacterial proteins detect chemicals in water

"Pharmaceutical residues are becoming increasingly a problem for the environment. Sewage plants do not decompose these substances completely. The problem will worsen if one considers, for example, the rising proportion of elderly people in our society who actually account for the increased consu... Read More

To Defeat Bacteria, Researchers Think Like Bacteria

A new approach to treating antibiotic-resistant infections has been developed by University of Wollongong (UOW) and University of New South Wales’ (UNSW) researchers who have patented the new technology and entered into commercialization discussions with two French pharmaceutical companies.

A... Read More

The Beginner's Mind in Learning...

In my newest blog post, I discuss how taking a "beginner's mind" approach leads to creativity, real learning, and enthusiasm. I tie together Suzuki's "Beginner's Mind" concept with Elio Schaechter's "Talmudic Questions," and give an example from one of my first seminars. Read More

How an Aggressive Fungal Pathogen Causes Mold in Fruits and Vegetables

A research team led by a molecular plant pathologist at the University of California, Riverside has discovered the mechanism by which an aggressive fungal pathogen infects almost all fruits and vegetables.

The team discovered a novel “virulence mechanism” — the mechanism by which infection ta... Read More

Trial and error

Italian officials should not go ahead with expensive clinical tests of an unproven stem-cell therapy that has no good scientific basis.

The Italian government is planning to oversee a clinical trial of a controversial stem-cell therapy. There are many reasons for the trial to be stopped — and... Read More

Twenty-six lectures in virology

In the spring of each year I teach a virology course to undergraduates and masters students at Columbia University. I produce video recordings of all my lectures not only for students in the course, but for anyone else who is interested in learning about viruses.

You can find my virology lect... Read More

Pithovirus: Bigger than Pandoravirus with a smaller genome

A new virus called Pithovirus sibericum has been isolated from 30,000 year old Siberian permafrost. It is the oldest DNA virus of eukaryotes ever isolated, showing that viruses can retain infectivity in nature for very long periods of time. Read More

Hepatitis C Remains Major Problem for HIV Patients Despite Antiretroviral Therapy

A new study led by researchers at the Perelman School of Medicine at the University of Pennsylvania has found that the risk of hepatitis C-associated serious liver disease persists in HIV patients otherwise benefitting from antiretroviral therapy (ART) to treat HIV.

It has been suggested that... Read More

Octopic cultivation

Cute octopus-like device for anaerobic cultivation of cellulolytic bacteria aimed to replace O2 with argon. Situated at the Faculty of Biology, Moscow State University, Russia. Read More

Gut Reaction: Human Colon Replica Demonstrates How E. coli Contaminates Groundwater

Scientists are great at growing E. coli in the lab. They know exactly under which conditions various strains thrive. Unfortunately, there is only so much that can be learned from the bacteria’s behavior in an ideal, isolated and ultimately unrealistic environment. That is why a group of research... Read More

Virus may be causing deadly coral 'white plague' epidemic in Caribbean

The Caribbean Sea is battling an epidemic — a nasty plague that spreads and kills quickly. Unlike the historical Black Plague, which killed millions of people in the Middle Ages, this so-called white plague is devastating populations of marine corals.

Scientists long believed the scourge, whi... Read More

Ice-cold methods decode bacterial infection systems

When attacking body cells, bacteria, such as salmonellae or Yersinia (plague pathogens), inject specific bacterial proteins through hollow, syringe-like structures – called injectisomes – into the host cells. These substances reprogram the cells and can thus overcome their defense. From then on,... Read More

JOSEPH LEIDY – 1823-1891

Joseph Leidy (1823-1891), naturalist, comparative anatomist, paleontologist, and microscopist, was dubbed by his biographer as “the last man who knew everything.” Leidy also made substantial contributions to the field of protozoology and is considered America’s first... Read More

Bacteria from lean mice prevent obesity in peers

But microbes are only part of the story — the effect also depends on a healthy diet. Gut bacteria from lean mice can invade the guts of obesity-prone cage-mates and help their new hosts to fight weight gain.

Researchers led by Jeffrey Gordon, a biologist at Washington University in St. Louis... Read More

Researchers develop a faster method to identify Salmonella strains

A method that promises to reduce by more than half the time it takes health officials to identify Salmonella strains has been developed by researchers in Penn State's College of Agricultural Sciences.

The finding is important because it promises to significantly speed up the response to many ... Read More

From Friend to Foe: How Benign Bacteria Evolve Into Virulent Pathogens

Bacteria can evolve rapidly to adapt to environmental change. When the "environment" is the immune response of an infected host, this evolution can turn harmless bacteria into life-threatening pathogens. A study published on December 12 in PLOS Pathogens provides insight into how this happens.
