Researchers in Japan have developed a low-intensity light source that allows cell biologists to visualize and handle live cells without destroying them during prolonged exposure. In addition to laying the foundation for new cell manipulations, the development will make advanced biology requiring... Read More
Did you know that your body is home to 10 times more microbes than human cells? Join us at ASM Headquarters on Thursday, July 19, 2012, from 6-8 PM to learn about the human microbiome and its fascinating practical applications. Come mingle with like-minded enthusiasts and curious citizens ove... Read More
So, there’s this thing. A big project. An investigative project, actually. I’ve been working on it for months, and finally I can tell you about it, because it all just published, in various venues, today.
I’ve been working with a great new group, the Food and Environment Reporting Network — o... Read More
Scientists have discovered two viruses that appear to infect the single-celled microalgae that reside in corals and are important for coral growth and health, and they say the viruses could play a role in the serious decline of coral ecosystems around the world.

We are still waiting with bated breath for the day scientists resurrect the woolly mammoth. Until then, we'll have to satisfy ourselves with resurrections of ancient plants and bacteria - which may be more amazing anyway, because they're even older. The dish in the above image holds a bacterium ... Read More
A group of diseases that kill millions of people each year can’t be touched by antibiotics, and some treatment is so harsh the patient can’t survive it. They’re caused by parasites, and for decades researchers have searched for a “magic bullet” to kill them without harming the patient. Now, a te... Read More
Rice University researchers report too small a dose may enhance microbes’ immunity
Rice University researchers have settled a long-standing controversy over the mechanism by which silver nanoparticles, the most widely used nanomaterial in the world, kill bacteria.
Their work comes with a ... Read More
t may sound like snake oil, but a new study suggests scorpion venom contains a substance that can fend off drug-resistant bacteria, including the deadly MRSA.
Drug resistance is increasingly rendering our antibiotic arsenal ineffective against bacteria. According to a CDC study, MRSA caused 3... Read More

Researchers Jose Cordova of Yale University and Erich Astudillo of Chile’s Universidad de Santiago discovered a molecule they call Keep 32 that kills the bacteria responsible for all the trauma you suffered as a child, lying down blinded by the light as a masked man poked bits of metal in your m...

To the left is a panel from a new paper in PLoS Genetics, Selection-Driven Gene Loss in Bacteria. The y-axis is selection, so above 0 represents a positive selection coefficient, and below a negative one. The lineages above the x-axis then are more fit against the baseline wild type (selection c... Read More

Scared of bird flu? How about the viral Rift Valley fever? These diseases and many others are animal diseases that have grown the ability to infect humans. They’re known as zoonoses. You heard it, zoonoses. And humanity’s ever-growing taste for livestock products could stoke the growth of these ... Read More
After 18 months of controversy, the official verdict is in: an arsenic-tolerant bacterium found in California’s Mono Lake cannot live without phosphorus.
In 2010, a group led by Felisa Wolfe-Simon, a microbiologist now at the Lawrence Berkeley National Laboratory in Berkeley, California, repo... Read More
I have been asked recently to write an article, somewhat along the lines of this one but longer, and with a somewhat different angle, asking a little bit different questions: What makes a science blog? Who were the first science bloggers and how long ago? How many science blogs are there? How do... Read More
Phase contrast image of fresh water unicellular algae Haematococcus pluvialis colelcted at 100X. This species is well known for its high content of the strong antioxidant astaxanthin, which is important in aquaculture, various pharmaceuticals, and cosmetics. Fourth Prize, 2009 Olympus BioScapes ... Read More
In 2009 researchers from the UT Health Science Center San Antonio and other institutions crack the genetic code of Schistosoma mansoni, a flatworm that can live up to 10 years on average in humans. The parasite is endemic in many tropical areas of the world.

By looking at signature chemical differences in the DNA of various immune cells called leukocytes, scientists have developed a way to determine their relative abundance in blood samples. The relative abundance turns out to correlate with specific cancers and other diseases, making the technique,... Read More
MISA researchers from SARDI have isolated and evaluated a ‘super strain’ of a native microalgae species that could form the basis of a local biofuels industry.
This breakthrough in biodiscovery comes after six years of ‘bioprospecting’ across thousands of kilometres of the State and into the ... Read More
I still wonder why the influenza virus H5N1 ferret transmission studies generated such fear and misunderstanding among the public, the press, and even some scientists. I still cannot fully explain what transpired, but now that the papers have been published some new clues have emerged. Read More
