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

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

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

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

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

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.

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

How a Young Boy, a Cow and a Milkmaid Helped to Conquer Smallpox [Video]

If you aren’t familiar with the TEDEd series of animated videos, you should be. The series pairs professional educators with top-notch animators to create short video “lessons” on a huge variety of topics in science, medicine and history.
 The latest episode features several of the early attempt... 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

First fungal farmers found harvesting bacteria

It's a mould breaker. Researchers have discovered the first fungus that behaves like a farmer.

We already know that soil fungi can help bacteria travel quickly from A to B. The fungal filaments provide favourable conditions for the bacteria, and so act as "highways" through the soil. But thes... Read More

Professor doesn’t overlook the small things in biology

Frog-killing fungi, the methods bacteria use to evade antibiotics, and the hidden microbes deep inside an Antarctic lake: These are just a few of the topics covered in “Small Things Considered,” a microbiology blog run by Moselio Schaechter. Schaechter is former president of the American Society... Read More

Changes in the Field Can Cut Food Contamination

Small shifts in agricultural practices can increase or reduce the risk of salmonella and listeria contamination on produce, new research shows.

For example, applying manure within a year of harvesting produce boosts the odds of contaminating a field with salmonella, which is the biggest singl... Read More

Best Way to Kill Lab Animals Sought

Researchers are gathering this week to debate the most humane methods of dispatching lab animals, which are primarily rodents. Killing research animals is one of the most unpleasant tasks in science, and it is imperative to do it as humanely as possible. But researchers who study animal welfare... Read More

Discovery May Aid Vaccine Design for Common Form of Malaria

A form of malaria common in India, Southeast Asia and South America attacks human red blood cells by clamping down on the cells with a pair of proteins, new research at Washington University School of Medicine in St. Louis has revealed.

The study provides details that will help scientists des... Read More

Penicillin equally effective as ‘big gun’ antibiotics for treating less severe childhood pneumonia

Children hospitalized for pneumonia have similar outcomes, including length of stay and costs, regardless of whether they are treated with “big gun” antibiotics such as ceftriaxone or cefotaxime or more narrowly focused antibiotics such as ampicillin or penicillin, according to a Vanderbilt stud...

Mating is the kiss of death for certain female worms

The presence of male sperm and seminal fluid causes female worms to shrivel and die after giving birth, Princeton University researchers reported this week in the journal Science. The demise of the female appears to benefit the male worm by removing her from the mating pool for other males.

Bacterial Cytological Profiling Global Video Challenge

Bacteria have evolved resistance to every known class of antibiotic, creating an urgent need for methods to identify new antibiotics that work by different mechanisms. We have developed a new approach to antibiotic discovery that provides a short cut for identifying antibacterial molecules and ... Read More
