2,300 tubes containing SARS virus samples missing in France

A major French biomedical research body, the Pasteur Institute, have launched an investigation into the disappearance of some 2,300 test tubes containing samples of the SARS virus. The loss was discovered during an inventory.

The Pasteur Institute filed a so-called 'complaint against X' on Mo... 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

Versatility in Genetic Expression Aids Rapid Microbial Evolution

Microbiologists from Trinity College Dublin have discovered that an identical protein is used differently by two species of bacteria to help them cope with distinct types of environmental stress. The discovery reveals an extraordinary level of versatility in the way different genes are ‘switched... 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

"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

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

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

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

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

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

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

Gold Nanoparticles Help to Develop a New Method for Tracking Viruses

Researchers at the Nanoscience Center (NSC) of University of Jyväskylä in Finland have developed a novel method to study enterovirus structures and their functions. The method will help to obtain new information on trafficking of viruses in cells and tissues as well as on the mechanisms of virus... Read More

Fungus could control mosquitoes, research suggests

Researchers at Swansea University say a fungus could be the key to controlling mosquitoes.

Fungus Metarhizium anisopliae lives in soil and kills a whole range of insects and researchers say it also affects mosquito larvae if added to the water where the insect breeds.

The insects carry dis... 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

Researchers discover a new protein fold with a transport tunnel

The protein LIMP-2 is vital for both humans and animals. If it is absent – due, for example, to a hereditary disease – substances of an unknown nature, probably lipids, accumulate in the organism. Up to now, scientists were unsure what the protein looks like and how exactly it functions. Privatd... 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

Living liquid crystals: Bacteria-filled liquid crystals could improve biosensing

Plop living, swimming bacteria into a novel water-based, nontoxic liquid crystal and a new physics takes over. The dynamic interaction of the bacteria with the liquid crystal creates a novel form of soft matter: living liquid crystal.

The new type of active material, which holds promise for i... 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

Unraveling bacterial behavior

Michael Laub studies the complex interactions that underlie cells’ responses to their environment. Bacteria encounter a constant barrage of ever-changing temperature, acidity and chemical stimuli from their environment. The cells must absorb all of this information and choose the correct respons... Read More
