Women have more diverse hand bacteria than men
A new University of Colorado at Boulder study indicates that not only do human hands harbor far higher numbers of bacteria species than previously believed, women have a significantly greater diversity of microbes on their palms than men.

Study demonstrates that bacterial clotting depends on clustering
Bacteria can directly cause human blood and plasma to clot—a process that was previously thought to have been lost during the course of vertebrate evolution, according to new research at the University of Chicago, National Institute of Allergy and Infectious Diseases, and Institut Pasteur in Paris. Their findings will be published online Nov. 2 in Nature Chemical Biology.

Bacteria manage perfume oil production from grass
Scientists in Italy have found bacteria in the root of a tropical grass whose oils have been used in the cosmetic and perfumery industries. These bacteria seem to promote the production of essential oils, but also they change the molecular structure of the oil, giving it different flavours and properties: termicidal, insecticidal, antimicrobial and antioxidant.

Tiny fungi may have sex while infecting humans
A team at Duke University Medical Center has proven that microsporidia are true fungi and that this species most likely undergoes a form of sexual reproduction during infection of humans and other host animals.

In decision to grow, bacteria follow the crowd

Predatory bacterial swarm uses rippling motion to reach prey
Like something from a horror movie, the swarm of bacteria ripples purposefully toward their prey, devours it and moves on.

Study helps clarify role of soil microbes in global warming
Current models of global climate change predict warmer temperatures will increase the rate that bacteria and other microbes decompose soil organic matter, a scenario that pumps even more heat-trapping carbon into the atmosphere.

New cell division mechanism discovered
A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. The study is published today in the online version the American National Academy of Sciences, PNAS.

Bacteria cause old buildings to feel off-color
The assumption that time, weather, and pollution are what cause buildings to decline is only partly true. Bacteria are also responsible for the ageing of buildings and monuments – a process known as biodeterioration, where organisms change the properties of materials through their vital activities.

Contact lenses are home to pathogenic amoebae
Contact lenses increase the risk of infection with pathogenic protozoa that can cause blindness. New research, published in the November issue of the Journal of Medical Microbiology, shows that a high percentage of contact lens cases in Tenerife are contaminated with Acanthamoeba that cannot be killed by normal contact lens solution.

When under attack, plants can signal microbial friends for help
Researchers at the University of Delaware have discovered that when the leaf of a plant is under attack by a pathogen, it can send out an S.O.S. to the roots for help, and the roots will respond by secreting an acid that brings beneficial bacteria to the rescue.

Scientists discover bacteria that can cause bone infections
Scientists have discovered that a bone infection is caused by a newly described species of bacteria that is related to the tuberculosis pathogen. The discovery may help improve the diagnosis and treatment of similar infections, according to an article published in the October issue of the International Journal of Systematic and Evolutionary Microbiology.

Bold traveler's journey toward the center of the Earth
The first ecosystem ever found having only a single biological species has been discovered 2.8 kilometers (1.74 miles) beneath the surface of the earth in the Mponeng gold mine near Johannesburg, South Africa. There the rod-shaped bacterium Desulforudis audaxviator exists in complete isolation, total darkness, a lack of oxygen, and 60-degree-Celsius heat (140 degrees Fahrenheit).

HIV drug maraviroc effective for drug-resistant patients
As many as one quarter of HIV patients have drug resistance, limiting their treatment options and raising their risk for AIDS and death. Now, maraviroc, the first of a new class of HIV drugs called CCR5 receptor antagonists, has been shown to be effective over 48 weeks for drug-resistant patients with R5 HIV-1, a variation of the virus found in more than half of HIV-infected patients.
