Tending the Body’s Microbial Garden

For a century, doctors have waged war against bacteria, using antibiotics as their weapons. But that relationship is changing as scientists become more familiar with the 100 trillion microbes that call us home — collectively known as the microbiome.

“I would like to lose the language of warfa... Read More

Meningitis Vaccine Being Developed From Common Cold Virus

A leading cause for meningitis and septicemia in the UK is meningococcus B (MenB) bacterium infection. Healthy children can become severely ill within just a few hours if they contract meningitis or septicemia, as both illnesses develop randomly and with alarming speed. It often occurs in babies...

Study upholds immune system’s role in autism

Changes in an overactive immune system can contribute to autism-like behaviors in mice, new research shows.

Scientists at the California Institute of Technology (Caltech) pioneered the study of the link between irregularities in the immune system and neurodevelopmental disorders such as auti... Read More

Some Like It Very Hot

Russian scientists have now poured 60 tonnes of freon and kerosene down the four-kilometre bore hole that plunges through the ice above Lake Vostok in Antarctica. This will stop the hole freezing up during the long Antarctic winter. When summer comes, the Russian team will return to drill the la... Read More

Aaron J. Shatkin, 77

Aaron J. Shatkin was well known for his work on reoviruses beginning in the 1960s in his laboratory at the Roche Institute of Molecular Biology in Nutley, NJ and then at Rutgers University. He was among the first to appreciate that virus particles contained many different enzymes, such as RNA po... Read More

Microbiologist Uses Viruses to Fight Bacteria

After a decade of research, ContraFect Corporation, a small biotech company based in Yonkers, N.Y., is preparing to test bacteriophages—viruses that infect and destroy bacteria—in people as a potential alternative to overused antibiotics for treating and preventing bacterial infections. The firs... Read More

The Extra Pounds You Can't Afford to Lose: An Interview With Microbiologist Margaret McFall-Ngai

Recent revelations about our microscopic partners and tenants are numerically startling, if not downright existential. Try these for starters: Most of the cells within your body are not human cells, and you are literally teeming with pounds of busy microbes, working to earn their keep while you ... Read More

Slow-Motion Microbes Still Living off Dino-era "Lunch Box"

Buried under the seafloor for 86 million years, a bacterial community lives so slowly it's still surviving on a "lunch box" from dinosaur days, a new study says. (See marine-microbe pictures.)

It's been known since the 1990s that microbes can live trapped in ocean sediments for millions of ye... Read More

Rapamycin, Easter Island Drug, Shows Promise In Boosting Aging Brain, Mice Study Shows

Scientists at the University of Texas Health Science Center San Antonio are investigating a potential new drug that could improve learning and memory during aging -- thanks to Easter Island?

The drug, called rapamycin, comes from isolated bacterial products in the soil of the Polynesian islan... Read More

Grow Your Own Computer?

There may be a new wave of computer technology on the way thanks to scientists at the University of Leeds and Japan’s University of Agriculture and Technology: Growing your own computer.

Magnet-making bacteria may be used to create the next generation of hard drives, making them much smaller ... Read More

Built-in dengue virus killer found in humans

Scientists may have hit gold in their fight against dengue. They have located a human antibody that can neutralise and kill its virus within two hours.

Significantly, they have also identified a way to reproduce this antibody in large quantities, potentially opening the door to a cure for den... Read More

Sheets of virus generate electricity when squished

Squishing a stack of virus sheets generates enough electricity to power a small liquid crystal display. With increased power output, these virus films might one day use the beating of your heart to power a pacemaker, the researchers behind them say.

Piezoelectric materials build up charge whe... Read More

Scientists: 10,000 germ species can live in/on healthy people

They live on your skin, up your nose, in your gut - enough bacteria, fungi and other microbes that collected together could weigh, amazingly, a few pounds.

Now scientists have mapped just which critters normally live in or on us and where, calculating that healthy people can share their bodi... Read More

19th Century Shipwreck Beer Could Be Recreated

Beer discovered two years ago onboard a shipwreck from the mid-1800s could possibly be recreated using living bacteria discovered in the brew, Finnish researchers announced last Thursday.

According to Terhi Kinnunen of Reuters, Annika Wilhelmson from VTT Technical Research Centre of Finland s... Read More

In First, Software Emulates Lifespan of Entire Organism

Scientists at Stanford University and the J. Craig Venter Institute have developed the first software simulation of an entire organism, a humble single-cell bacterium that lives in the human genital and respiratory tracts.

The scientists and other experts said the work was a giant step toward... Read More

The Rise of Genomic Superspreaders

One hundred million years ago the earth’s climate was much warmer than today and vast inland seas stretched across entire continents. The land was dominated by charismatic megafauna that would one day serve as inspiration for Sir Arthur Conan Doyle’s novel The Lost World. This period is commonly... Read More

How hosts recognize bacteria

We are surrounded by bacteria, viruses, fungi and parasites. The fact that we nevertheless do not fall prey to infections is thanks to certain cellular sensor molecules such as toll-like receptors (TLR), which recognize the molecular structure of pathogens and intercede by ensuring an often comp...

Friendly Fungi: Elucidating the fungal biosynthesis of stipitatic acid

In a tale worthy of Sherlock Holmes, scientists in the School of Chemistry at the University of Bristol, UK have solved a biochemical mystery that had previously proven elusive for 70 years: How the fungus Talaromyces stipitatus produces stipitatic acid (6), which is a tropolone, one of an atypi...

Bacterial Vaginosis Is Associated with Higher Risk of Female-to-Male Transmission of HIV

An investigation led by UCSF has found that the risk of female-to-male HIV transmission is increased three fold for women with bacterial vaginosis, a common disorder in which the normal balance of bacteria in the vagina is disrupted.

The new research assessed the association between bacterial... Read More
