Research identifies how bacteria produce hydrogen

Making hydrogen easily and cheaply is a dream goal for clean, sustainable energy. Bacteria have been doing exactly that for billions of years, and now chemists at the University of California, Davis, and Stanford University are revealing how they do it, and perhaps opening ways to imitate them.

Unknown Floor isolate #2

Partial isolate of an unknown organism on trypticase soy agar exhibiting spreading and mounding in an irregular-rhizoid form with lobate margins. The colony exhibited an opaque yellow-orange pigment with a mucoid surface. This sample was obtained from a floor swab and incubated at 37°C. Read More

Growth on Manital Salt Agar of Staphylococcus aureus and staphylococcus epidermis isolated from wounds

These clinical isolates are from Medinipur Medical College. Read More

How brain guards itself against virus attacks

Infections in the central nervous system are rare thanks to our brain's unique defence system that prevents viruses from invading, finds a study. The research explains a long-standing mystery.

Microbes Defy Rules of DNA Code

The instructions encoded into DNA are thought to follow a universal set of rules across all domains of life. But researchers report in the May 23 issue of Science that organisms routinely break these rules.

The finding has implications for the design of synthetic life: by designing organisms ... Read More

Reduced glycopeptide and lipopeptide susceptibility in Staphylococcus aureus and the “seesaw effect”: Taking advantage of the back door left open?

Methicillin-resistant S. aureus (MRSA) constitutes approximately 50% of clinical S. aureus isolates and is most commonly the result of production of a mutated pencillin-binding protein, PBP2a, which is able to carry out essential cell wall synthesis functions while maintaining a low-affinity for...

On Teaching

A graduate student came to my office recently to say that she was increasingly bothered by anxiety and the ‘terror’ of having to speak at laboratory meetings. She had also learned a month ago that she was expected to lecture to a class organized by her mentor. The thought of having to lecture to... Read More

Herpes infected humans before they were human

Researchers have identified the evolutionary origins of human herpes simplex virus (HSV) -1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans -- H...

Gut Bacteria Lose their Tails to Evade Antibodies

New research reveals the complex dynamic between gut bacteria and the immune system that keeps proteins from flagellin—bacterial tails—under control.

In healthy individuals, the only thing that separates the lining of the human gut from the some 100 trillion bacterial cells in the gastrointes... Read More

Amber discovery indicates Lyme disease is older than human race

Lyme disease is a stealthy, often misdiagnosed disease that was only recognized about 40 years ago, but new discoveries of ticks fossilized in amber show that the bacteria which cause it may have been lurking around for 15 million years – long before any humans walked on Earth.

The findings w... Read More

Unknown floor isolate

Partial isolate of an unknown organism on trypticase soy agar exhibiting spreading and an irregular-rhizoid form with lobate margins. The pigment is opaque white-beige with a mucoid surface over most of the colony. A dry, dull, matte surface appears toward the outer edges of the colony. The s... Read More

Researchers find chemicals that treat citrus greening in the lab

A University of Florida research team is cautiously optimistic after finding a possible treatment in the lab for citrus greening, a disease devastating Florida’s $9 billion citrus industry. It is the first step in a years-long process to bring a treatment to market.

Claudio Gonzalez and Graci... Read More

Taxis, Planes and Viruses: How Deadly Ebola Can Spread

For scientists tracking the deadly Ebola virus in West Africa, it is not about complex virology and genotyping, but about how contagious microbes - like humans - use planes, bikes and taxis to spread.

So far, authorities have taken no action to limit international travel in the region. The ai... Read More

New Wearable Device Could Protect Against HIV and Pregnancy

If a sexually active woman wants to protect herself from unwanted pregnancy and HIV using a single method, she has always been limited to condoms. A new paper, released today in PLOS ONE details a first-of-its-kind device that provides an alternative.

Metallo-β-lactamase producing Acinetobacter species

Acinetobacter species are among the most common nosocomial pathogens that are notorious for multi-drug resistance. Their immense ability to acquire or upregulate antibiotic drug resistance determinants has established them as a successful pathogen, causing wide range of infections such as wound ... Read More

Fungal pathogen shows profound effects from spaceflight

At Arizona State University’s Biodesign Institute, Cheryl Nickerson and her team have been investigating the intriguing effects of spaceflight on microbial pathogens.

In a new paper appearing in the current issue of the journal PLOS ONE, the team reports their recent work examining spacefligh... Read More

Malaria-carrying mosquitoes wiped out in lab with genetic method that creates male-only offspring

Scientists have modified mosquitoes to produce sperm that will only create males, pioneering a fresh approach to eradicating malaria. Since 2000, increased prevention and control measures have reduced global malaria mortality rates by 42 per cent, but the disease remains a prevalent killer espec... Read More

Rare 'polio-like' disease reports

US doctors are warning of an emerging polio-like disease in California where up to 20 people have been infected.

A meeting of the American Academy of Neurology heard that some patients had developed paralysis in all four limbs, which had not improved with treatment.

The US is polio-free, b... Read More

A quicker, cheaper way to detect staph in the body

Probe identifies staph bacteria without need for biopsies. Chances are you won’t know you’ve got a staph infection until the test results come in, days after the symptoms first appear. But what if your physician could identify the infection much more quickly and without having to take a biopsy a... Read More

A microbe's fountain of youth

The yeast S.pombe is one of the best-studied microbes in the world. First isolated from East African millet beer over a century ago, it's been used as a model organism in molecular and cell biology for the past sixty years. And yet scientists have now just uncovered what may be its most striking... Read More
