An international team of scientists has for the first time observed an evolutionary strategy called 'bet hedging' under laboratory conditions. The term bet hedging describes the way in which organisms ensure the survival of their species in rapidly changing environments by generating offspring s... Read More
Experts on both sides of the Atlantic applaud President Barack Obama and Swedish Prime Minister Fredrik Reinfeldt, representing the European Union (EU) Presidency, for establishing a transatlantic task force to address antibiotic resistance, an urgent and growing problem that threatens patient s...

"As we head into flu season, the hysteria is ramping up all over again, and what that really means is profit! From body suits, to vaccines, emergency food packs, and underground bunkers.... Read More
When humans eventually travel to Mars and beyond, they'll have plenty to worry about along with the discomforts of eating freeze-dried food and drinking their own urine. A new report says they will probably be really sick, to boot -- from flare-ups of E. coli, chicken pox or staph infections.

French scientists mixed gene therapy and bone marrow transplants in two boys to seemingly halt a brain disease that can kill by adolescence. The surprise ingredient: They disabled the HIV virus so it couldn't cause AIDS, and then used it to carry in the healthy new gene.
The experiment marks ... Read More
Not long ago, gene therapy seemed troubled by insurmountable difficulties. After decades of hype and dashed hopes, many who once embraced the idea of correcting genetic disorders by giving people new genes all but gave up the idea
But scientists say gene therapy may be on the edge of a resurg... Read More
Antarctica's icy lakes are home to a surprisingly diverse community of viruses, including some that were previously unidentified.
At first glance, Antarctica's freshwater lakes don't seem very hospitable to life. They remain frozen for a good nine months out of the year, and they contain very... Read More
A recent paper in the Journal of Microbiology and Biology Education by Christine Vatovec and Teri Balser examines the effectiveness of using podcasts as an educational tool.
Out of 209 survey respondents, the authors found:
"The majority of students reported enjoying using the podcasts in... Read More
A University of Colorado at Boulder team has developed the first atlas of bacterial diversity across the human body, charting wide variations in microbe populations that live in different regions of the human body and which aid us in physiological functions that contribute to our health.
The ... Read More
Antibacterial soap, hand sanitizer and antibiotics are all substances that we use in an attempt to kill bacteria that might make us sick.Whether we are concerned about getting strep throat, bacterial meningitis or something else, these prevention methods can offer protection.
However, some ba... Read More
Mucus is more than gross--it's a critical barrier against disease, trapping many of the germs that want to invade your body. A wet mesh of proteins, antiseptic enzymes and salts, mucus is what keeps all but a few microbes from wreaking havoc on many of our most exposed tissues.
Helicobacter p... Read More
Direct industry funding for academic life science research appears to have decreased in the last decade, according to the results of a 2007 survey published this week.
The survey also found that academic life scientists with industry support withheld data or delayed publication due to commerc... Read More
In plant and animal innate immunity, like many of the dances of life, it takes two to tango. A receptor molecule in the plant pairs up with a specific molecule on the invading bacteria and, presto, the immune system swings into action to defend against the invasion of the disease-causing microbe...

Your body is home to 10 times as many microbes as its own cells. But they can be quite picky about where they will settle – and what other bacteria they'll share fences with.
That's the conclusion of the most comprehensive map ever of the microbial communities flourishing in the human body.

A short Q&A session that regularly runs in the New York Times. This week, pets and H1N1 are discussed by Dr. Louise Murray, director of medicine at the A.S.P.C.A. Bergh Memorial Animal Hospital in New York City. Read More
Many hands—or many flagella—make light work.
In studies of the motion of tiny swimming bacteria, scientists at the U.S. Department of Energy's Argonne National Laboratory found that the microscopic organisms can stir fluids remarkably quickly and effectively. As a result, the bacterial flagel... Read More
Vets in the US state of Iowa said a household cat had tested positive for swine flu - the first known case in the world of the new pandemic strain spreading to the feline population.
The domestic shorthair, a 13-year-old castrated male, apparently caught A(H1N1) off its owners - two of the th... Read More
n the future, bacteria could harness solar energy to provide power for automobiles if an ASU project recently granted $5.2 million by the U.S. Department of Energy succeeds.
A program in the energy department chose only 37 of 3,500 initial applicants to receive grants.
ASU professor Willem... Read More
Planarians may be lowly flatworms, but the tiny crawlers possess powers that even superheroes would envy. Cut off the worm’s head or tail, and a new one sprouts to replace it. In the flatworm’s body, nerves, muscles, connective tissues, and whole organs regenerate when damaged or removed.
