Study of planarian hormones may aid in understanding parasitic flatworms

A study of peptide hormones in the brain of a seemingly primitive flatworm reveals the surprising complexity of its nervous system and opens up a new approach for combating a major parasitic disease, researchers report.

The planarian flatworm, Schmidtea mediterranea, is perhaps best known for... Read More

NIH studies influence revision of WHO guidelines for treating HIV-infected women, infants

Two studies appearing in the October 14, 2010 New England Journal of Medicine and funded by the National Institutes of Health helped influence the World Health Organization (WHO) to change its guidelines this year for the treatment of HIV infection in certain women and children. The recently up... Read More

Newer flu vaccine as effective as traditional one

A flu vaccine made through a speedier production method appears to be as safe and effective as one produced in the traditional way, a study suggests.

The conventional flu vaccine is produced using chicken eggs to grow the virus, a slow process that makes it hard to quickly boost production in... Read More

Genomic comparison of ocean microbes reveals East-West divide in populations

Much as an anthropologist can study populations of people to learn about their physical attributes, their environs and social structures, some marine microbiologists read the genome of microbes to glean information about the microbes themselves, their environments and lifestyles.

Malaysia will use genetically modified mosquitoes to fight dengue

Malaysia could be the first country in Asia to use genetically modified mosquitoes to battle a rise in dengue fever, government authorities said Monday. Read More

Bioluminescence helps organisms to breed, feed and evade predators

Bioluminescence is as widespread as it is wild and mysterious. Jack-o'-lantern mushrooms, flashlight fish and fireflies are among the multitude of organisms that bioluminesce. Scientists are still finding previously unknown examples of the phenomenon, especially at sea, where bioluminescent spec... Read More

How bacteria resist antibiotics

Researchers have discovered the crystal structures of pumps that remove heavy metal toxins from bacteria, making them resistant to antibiotics.

The finding offers a better understanding of bacterial resistance to antibiotics that could ultimately help drug researchers develop treatments to co... Read More

Easy way to track phytoplankton

It’s now much easier to pinpoint biological hot spots in the world’s oceans where some inhabitants are smaller than, well, a pinpoint.

Researchers have built a device that can count and classify microscopic algae called phytoplankton that range in size from one to hundreds of microns—the smal... Read More

Microbes grow electrifying whiskers

Some bacteria grow electrical hairs, known as nanowires, that let them link up in big biological circuits.The discovery suggests that microbial colonies may survive, communicate, and share energy in part through electrically conducting hairs.

The finding is reported this week in Proceedings ... Read More

Top 20 Microscope Photos of the Year (2010)

The subject of this year’s top microscope photo in the 36th annual Nikon Small World competition looks more like neon suspension bridges or sailboats than what it really is: mosquito heart muscle magnified 100 times.

The image, which used flourescence technology to highlight different parts o... Read More

The “Indian Superbug”: Worse Than We Knew

Just about a month ago, the disease-geek world was riveted by news of the “Indian superbug“: common bacteria carrying a newly recognized gene that confers profound multi-drug resistance, and that was linked to travel between Europe and South Asia, especially for medical tourism.

The gene, whi... Read More

First comprehensive survey of gut, mouth and arterial bacteria finds links to heart disease

The same types of bacteria found in arterial plaque, which causes atherosclerosis, are also found in the mouth and gut, according to the first general survey of all bacteria found in plaques from the mouth, gut and blood.

The study, conducted by researchers from Cornell and University of Goth... Read More

Hope for a New Treatment for Bone Cancer: Can 'Friendly' Bacteria Kill Cancer Cells?

Children and young people who are diagnosed with bone cancer could benefit from better treatment in the future, thanks to new research at The University of Nottingham.

The Bone Cancer Research Trust has launched Bone Cancer Awareness Week and has funded a new project at the University which i... Read More

The Catch of the Day: Bacterial Lobster Traps

It’s the kind of microbiology that would make Steve Irwin proud: tracking and trapping the wild Pseudomonas aeruginosa to study its habits. In mBio’s latest paper, the authors describe using “bacterial lobster traps”, picoliter-scale, permeable protein cages, to study quorum-sensing among small... Read More

Gambling on bacteria

Microorganisms offer lessons for gamblers and the rest of us, Tel Aviv University research says

When it comes to gambling, many people rely on game theory, a branch of applied mathematics that attempts to measure the choices of others to inform their own decisions. It's used in economics, pol... Read More
