Knowing the hunting habits of Karlodinium veneficum could help reduce fish kills, researchers at Johns Hopkins University, Baltimore, said... Read More

Koch’s postulates in the 21st century

For thousands of years, epidemics of contagious diseases were believed to be caused by the wrath of the gods, configuration of stars, or miasma. The association of specific microorganisms with disease came about as a consequence of the work of the German physician Robert Koch. He formulated a se... Read More

Membrane-Coat Proteins: Bacteria Have Them Too

Although they are present almost everywhere, on land and sea, a group of related bacteria in the superphylum Planctomycetes-Verrucomicrobia-Chlamydiae, or PVC, have remained in relative obscurity ever since they were first described about a decade ago. Scientists at the European Molecular Biolog... Read More

Pregnant woman's gingivitis caused baby to be stillborn, scientists say

Pregnant women with untreated gum disease may have more at stake than just their teeth. They may also be risking the lives of their babies, a new study shows.

Expectant mothers have long been warned that gum disease can cause a baby to be born prematurely or too small. But for the first time ... Read More

Ancient Organism Fights MRSA

Scientists studying an ancient metazoan organism discover antimicrobial peptide active against MRSA. Read More

Can Hookworms Help Humans?

Conditions with an immunological basis, such as multiple sclerosis, might be ameliorated by means of the helminth parasites that cause chronic ill-health in the tropics Read More

Downfall of the Dinosaurs

Microscopic parasites rather than Mesozoic-era predators might explain some otherwise puzzling damage being detected in dinosaur fossils. Read More

60 of the World's most memorable research papers

The Royal Society, founded in London in 1660 and one of the world's oldest scientific institutions, is marking the start of its 350th year by putting 60 of its most memorable research papers online. Several of these documents include papers by Sir Isaac Newton, Benjamin Franklin, and even Antoni... Read More

A note for the next pandemic: Face masks might be the way to go after all

Wear the face mask? Don't wear the face mask? The question may seem moot now -- what with a decline in H1N1 cases and pharmacies now publicly trumpeting the availability of vaccine against the influenza strain -- but a few months back, it was anything but academic.

Researchers at the Universi... Read More

Double Trouble: Bacterial Super-Infection After the Flu

Current research suggests that the flu may predispose to secondary bacterial infections, which account for a significant proportion of mortality during flu pandemics.

A common complication of flu infection is a secondary "super-infection" by bacteria, which greatly increases the morbidity and... Read More

Slime mold validates efficiency of Tokyo rail network

What do Tokyo commuter-rail designers and the slime mold Physarum polycephalum have in common? The two will build strikingly similar networks.

A Japan-based research team found that if they placed bits of food (oat flakes) around a central Physarum in the same location as 36 outlying cities a... Read More

Genetics Used to Track Transmission of MRSA Bacteria

New technology has made it possible, for the first time, to track the potentially deadly bacteria MRSA around the world or from one person to another, a new study reports.

The ability to track MRSA (methicillin-resistant Staphylococcus aureus) can help scientists figure out how the bacteria m... Read More

Marshall Nirenberg, Biologist Who Untangled Genetic Code, Dies at 82

Marshall W. Nirenberg, a biologist who deciphered the genetic code of life, earning a Nobel Prize for his achievement, died Friday at his home in Manhattan. He was 82.

The cause was cancer, said his stepdaughter Susan Weissman.

In solving the genetic code, Dr. Nirenberg established the rul... Read More

Llama Proteins Could Play a Vital Role in the War on Terror

Scientists at the Southwest Foundation for Biomedical Research (SFBR) have for the first time developed a highly sensitive means of detecting the seven types of botulinum neurotoxins (BoNTs) simultaneously.

The BoNT-detecting substances are antibodies -- proteins made by the body to fight dis... Read More

Retail Meat Linked to Urinary Tract Infections: Strong New Evidence

Chicken sold in supermarkets, restaurants and other outlets may place young women at risk of urinary tract infections (UTI), McGill researcher Amee Manges has discovered. Samples taken in the Montreal area between 2005 and 2007, in collaboration with the Public Health Agency of Canada and the Un... Read More

Bacteria rewired to flash in sync

Glowing bacteria that flash on and off together are pointing the way towards implants made of engineered cells that would deliver precise doses of drugs or hormones at specific times of the day.

The bacteria have been engineered to fluoresce in synchronised bursts to produce waves ... Read More

Viruses use 'hive intelligence' to focus their attack

This video from Geoffrey Smith and his team of virologists at Imperial College London shows how vaccinia virus spreads through cells. What's interesting about this is that when the virus leaves one cell in search of another to infect, vaccinia would bounce off of or hop over cells that were alre... Read More
