Some carbon nanotubes used for strengthening plastics may have an adverse effect on soil microbiology.
Specifically, these raw, non-functionalized single-walled carbon nanotubes were shown to damage the active microbes in low-organic soil.

A new study could provide the link that scientists have been looking for to confirm that reactivation of a latent herpes virus is a cause of some heart problems.
Looking at blood samples from 299 heart patients, researchers at Ohio State University found that those who had suffered a heart at... Read More
At least 20% of people, including half of schoolchildren, were infected with swine flu during the first year of the pandemic in 2009, according to data from 19 countries.
It is thought the virus killed 200,000 people around the world.
A World Health Organization-led study looked for eviden... Read More
Business Week interview with a fashion designer who makes her collection from bacteria:
This is really in its infancy, no?
I’m still very much focusing on apparel and luxury products—jewelry, things that use small amounts of material. The lab materials are quite expensive and are not being p... Read More
Researchers at the Paris Cardiovascular Research Center (PARCC) have shown how adhesion of Neisseria (N.) meningitidis to human microvessels in a humanized mouse model leads to the characteristic cutaneous lesions of meningococcal sepsis. This work, published on January 24 in the Open Access jou... Read More
Professors, you've discussed this idea before, but I thought you'd enjoy this nice summary from Nature:
Every minute of its existence, a living cell must assess and analyze myriad bits of information—everything from the temperature of its environment to the chemical makeup of its surroundings. Sometimes, these inputs cause a cell to change how it functions, but other times, the information may not... Read More
Researchers from computer firm IBM say they have invented a new non-toxic gel that can kill deadly drug-resistant bacteria by cutting through the sludge that shelters them and attacking the germ's cell membrane.
If verified, the finding could herald a breakthrough in the fight against the sup... Read More
The alarm system the helps immune system cells destroy invading bacteria points to a potentially new way to protect people from biological weapons, researchers report.
Cells in the immune system called macrophages normally engulf and kill intruding bacteria, holding them inside a membrane-bou... Read More
The highest rates of infection were in children, with 47 per cent of those aged five to 19 showing signs of having caught the virus. Older people were affected less, with only 11 per cent of people aged 65 or older becoming infected.
The findings come from an international collaboration led b... Read More
The polio virus has been found in the sewers of Cairo, and it appears to have come from Pakistan, the World Health Organization said Wednesday. Egypt has not had a case of polio since 2004. A vaccination drive is being planned for Feb. 25, and health workers are canvassing the neighborhoods wher... Read More
What cancerous conditions lead to what kinds of bacterial infections? If doctors knew, they could predict which patients would likely benefit from pre-treatment with certain kinds of antibiotics. A University of Colorado Cancer Center study published in this month's issue of the International Jo... Read More
A common type of bacteria may help pigs stay healthy during weaning. In a study of 36 weanling-age pigs, researchers found that a dose of lipid-producing Rhodococcus opacus bacteria increased circulating triglycerides. Triglycerides are a crucial source of energy for the immune system.

Virology was born in 1898, and has suffered from sampling bias ever since. For decades, viruses were defined by what they were not: not as big as a bacterium, not visible with a microscope, not culturable in the absence of a host. At the dawn of the 20th century, undiscovered viruses and aspirin... Read More
The storm clouds in Earth's atmosphere are filled with microbial life, according to a new study.
The research, published today (Jan. 23) in the journal PLoS One, revealed that hailstones drawn from storm clouds harbor several species of bacteria that tend to reside on plants, as well as thous... Read More
In early 2012 influenza virus researchers around the world decided to stop working on highly pathogenic avian influenza H5N1 virus. This decision came after work from the Fouchier and Kawaoka laboratories revealed the isolation of influenza H5N1 strains that can be passed among ferrets by aeroso... Read More
A toxin-antitoxin system is a set of two or more closely linked genes that together encode both a protein 'poison' and a corresponding 'antidote'. There are 3 types of these systems: Type I toxin-antitoxin systems rely on the base-pairing of complementary antitoxin RNA with the toxin's mRNA, Ty... Read More
