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

Assortment in colony biofilms

Effect of founder cell density on the spatial pattern formation in colony biofilms.
The colony biofilms were obtained by following the protocol described in van Gestel et al (2014) ISME Journal (doi: 10.1038/ismej.2014.52). Briefly, GFP and mKATE2 labeled Bacillus subtilis strain were mixed in ... 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

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

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.

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

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

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

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

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

New MRSA superbug emerges in Brazil

HOUSTON – (April 16, 2014) – An international research team led by Cesar A. Arias, M.D., Ph.D., at The University of Texas Health Science Center at Houston (UTHealth) has identified a new superbug that caused a bloodstream infection in a Brazilian patient. The report appeared in the April 17 iss... 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

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

"Crowdsourced" Microbes Heading to the Space Station

NASA Public Affairs Officer Dan Huot talks with Dr. David Coil about Project MERCCURI, which will study a "crowdsourced" collection of microbial samples scheduled to launch to the International Space Station aboard the SpaceX-3 mission.

Mix Of Gut Microbes May Play Role In Crohn's Disease

More than a million Americans suffer from Crohn's, which seems to start when an overreactive immune system causes abdominal pain, diarrhea, bleeding, weight loss and other symptoms. Many patients have to take powerful steroids (which can have serious side effects), and some have parts of the dig... 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.
