A detailed analysis of black carbon -- the residue of burned organic matter -- in computer climate models suggests that those models may be overestimating global warming predictions.   view more (2008-11-20)

Climate change opens new avenue for spread of invasive plants
Plants that range northward because of climate change may be better at defending themselves against local enemies than native plants.   view more (2008-11-20)

Antibiotics Can Cause Pervasive, Persistent Changes to the Microbial Community in the Human Gut, MBL and Stanford Scientists Report
Using a novel technique developed by Mitchell Sogin of the Marine Biological Laboratory (MBL) to identify different types of bacteria, scientists have completed the most precise survey to date of how microbial communities in the human gut respond to antibiotic treatment.   view more (2008-11-19)

Parasites that live inside cells use loophole to thwart immune system
St. Jude Children's Research Hospital scientists have discovered a mechanism by which intracellular pathogens can shut down one of the body's key chemical weapons against them: nitric oxide.   view more (2008-11-04)

New type of fuel found in Patagonia fungus
A team led by a Montana State University professor has found a fungus that produces a new type of diesel fuel, which they say holds great promise.   view more (2008-11-04)

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.   view more (2008-10-29)

Deep biosphere research points to new methods for recovering petroleum
Miles below us, deep within Earth's crust, life is astir. Organisms there are not the large creatures typically envisioned when thinking of life.   view more (2008-10-08)

JDRF funded study links 'hygiene hypothesis' to diabetes prevention
A research study funded by JDRF suggests that a common intestinal bacteria may provide some protection from developing type 1 diabetes. The findings provide an important step towards understanding how and why type 1 diabetes develops in people, and may lead to potential cures.   view more (2008-10-07)

Disinfectants can make bacteria resistant to treatment
Chemicals used in the environment to kill bacteria could be making them stronger, according to a paper published in the October issue of the journal Microbiology. Low levels of these chemicals, called biocides, can make the potentially lethal bacterium Staphylococcus aureus remove toxic chemicals... view more (2008-10-06)

Beetles get by with a little help from their friends
Humans living in communities often rely on friends to help get what they need and, according to researchers in the lab of Cameron Currie at the University of Wisconsin-Madison, many microbes, plants and animals benefit from 'friendly' associations too.   view more (2008-10-03)

Study reveals an oily diet for subsurface life
Thousands of feet below the bottom of the sea, off the shores of Santa Barbara, single-celled organisms are busy feasting on oil.   view more (2008-10-01)

Cancer-causing gut bacteria exposed
Normal gut bacteria are thought to be involved in colon cancer but the exact mechanisms have remained unknown. Now, scientists from the USA have discovered that a molecule produced by a common gut bacterium activates signalling pathways that are associated with cancer cells.   view more (2008-09-22)

Protein opens hope of treatment for cystic fibrosis patients
Scientists have finally identified a direct role for the missing protein that leaves cystic fibrosis patients open to attack from lung-damaging bacteria, the main reason most of them die before their 35th birthday, scientists heard today (Thursday 11 September 2008) at the Society for General... view more (2008-09-11)

As Andean glacier retreats, tiny life forms swiftly move in, CU-Boulder study shows
A University of Colorado at Boulder team working at 16,400 feet in the Peruvian Andes has discovered how barren soils uncovered by retreating glacier ice can swiftly establish a thriving community of microbes, setting the table for lichens, mosses and alpine plants.   view more (2008-09-09)

Infections linked to premature births more common than thought, Stanford study finds
Previously unrecognized and unidentified infections of amniotic fluid may be a significant cause of premature birth, according to researchers at the Stanford University School of Medicine.   view more (2008-08-26)

Novel fungus helps beetles to digest hard wood
A little known fungus tucked away in the gut of Asian longhorned beetles helps the insect munch through the hardest of woods according to a team of entomologists and biochemists. Researchers say the discovery could lead to innovative methods of controlling the invasive pest, and potentially offer... view more (2008-08-19)

Cataloguing invisible life: Microbe genome emerges from lake sediment
When entrepreneurial geneticist Craig Venter sailed around the world on his yacht sequencing samples of seawater, it was an ambitious project to use genetics to understand invisible ecological communities. But his scientific legacy was disappointing - a jumble of mystery DNA fragments belonging to... view more (2008-08-18)

Analysis of Lake Washington microbes shows the power of metagenomic approaches
Today's powerful sequencing machines can rapidly read the genomes of entire communities of microbes, but the challenge is to extract meaningful information from the jumbled reams of data.   view more (2008-08-18)

Microbes, by latitudes and altitudes, shed new light on life's diversity
Microbial biologists, including the University of Oregon's Jessica L. Green, may not have Jimmy Buffett's music from 1977 in mind, but they are changing attitudes about evolutionary diversity on Earth, from oceanic latitudes to mountainous altitudes.   view more (2008-08-12)

New bacterial species found in human mouth
Scientists have discovered a new species of bacteria in the mouth. The finding could help scientists to understand tooth decay and gum disease and may lead to better treatments, according to research published in the August issue of the International Journal of Systematic and Evolutionary... view more (2008-08-11)

Microbes beneath sea floor genetically distinct
Tiny microbes beneath the sea floor, distinct from life on the Earth's surface, may account for one-tenth of the Earth's living biomass, according to an interdisciplinary team of researchers, but many of these minute creatures are living on a geologic timescale.   view more (2008-07-22)

Protein marker for schizophrenia risk
A protein found in immune cells may be a reliable marker for schizophrenia risk, report researchers in a new proteomics study appearing in the July issue of Molecular and Cellular proteomics.    view more (2008-07-09)

Thinking ahead: Bacteria anticipate coming changes in their environment
A new study by Princeton University researchers shows for the first time that bacteria don't just react to changes in their surroundings -- they anticipate and prepare for them. The findings, reported in the June 6 issue of Science, challenge the prevailing notion that only organisms with complex... view more (2008-06-19)

Mini subs to probe odd structures in BC lake
Single person submersibles have been called in to help scientists retrieve samples from a lake in northern British Columbia that may hold vital clues to the history of life on Earth and on other planets.   view more (2008-06-17)

Climate change could impact vital functions of microbes
Global climate change will not only impact plants and animals but will also affect bacteria, fungi and other microbial populations that perform a myriad of functions important to life on earth.   view more (2008-06-03)
