The Army’s got a one-two punch to perfect vaccinations and offer scientists the ability to quickly develop inoculations that stave off new dangers. First, they’ll shoot troops up using a “gene gun,” that’s filled with DNA-based vaccines. Then they’ll follow it up with “short electrical pulses to... Read More
Scientists have made an important discovery that could lead to new drugs that reduce the severity of blood infections leading to sepsis. Research presented in the August 2010 issue of Journal of Leukocyte Biology (http://www.jleukbio.org) shows how interfering with the function of the cell membr... Read More
The vast majority of pediatricians and family physicians nationally are offering the human papillomavirus (also called HPV) vaccine, though fewer physicians are strongly encouraging it for 11- to 12-year-old girls as recommended by national guidelines, according to a survey in the September issu...

Although individuals who are HIV positive can now expect to live longer because of the availability of anti-retroviral drugs, this advance brings on new health challenges. It is estimated that the majority of the HIV-infected population of the United States will be older than 50 by 2015.

If you test enough flour you can find some contaminated by the potentially deadly pathogen--E. coli O157:H7--but testing probably is not going to do much when it comes to making flour safe to eat.
So concluded three speakers--Cargill's Joe Shebuski, Nestlé's Tim Jackson, and ConAgra's Ben War... Read More
The bacteria strain responsible for turning thousands mozzarella cheese blue blue earlier this summer does not pose a human health hazard, said German authorities.
The German Federal Institute for Risk Assessment (BfR) said the risk from the family of Pseudomonad bacteria that spoiled up to ... Read More
Researchers have been trying to make artificial spider silk--a lightweight, tougher-than-steel material that could have countless industrial applications--for decades. In an important step toward that goal, researchers at Tufts University have created genetically engineered microbes that produce... Read More
African children who eat a high-fiber diet (and the occasional wood-digesting insect) have gut bacteria that help them digest plant fibers and protect them from diarrhea and inflammatory disease, a new study finds. The research may lead to new probiotics that improve the digestive health of West... Read More
Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.
Carbon nanoparticles activated by bursts of laser light trigger the tiny ... Read More
DuPont and USDA will be developing a test for the detection of "Big 6" non-O157 shiga toxin-producing E. coli pathogens in food, which in recent years have been identified as agents of food-borne illnesses. The O157:H7 STEC strain of E. coli is already associated with global food contamination o... Read More
Scientists say this year that the "dead zone" area that forms every summer in the Gulf of Mexico is one of the largest ever measured.
The large area of low oxygen that chokes marine life comes in addition to the massive BP oil spill.
Microbes that eat the oil can deplete oxygen in the wate... Read More
In a bid to search for new drug discoveries, researchers are using one of the world’s most advanced microscopic scanners to study bacteria taken from mud samples recovered from the deepest place on Earth – the Mariana Trench.
The findings could pave the way for the creation of life-saving dru... Read More
In 1913, as the automobile zoomed into American life, The Outing Magazine gave its readers a bit of background on what fueled the new motorcars in “The Story of Gasoline.” After a brief vignette describing the death of “old Colonel Stegosaurus Ugulatus,” the article explained that “yesterday you...

Chanock received his MD in 1947 from the University of Chicago, and after clinical training in pediatrics (note the bowtie), joined Albert Sabin at the University of Cincinnati where he studied arthropod-borne viruses. After a stint in the US Army, he rejoined Sabin’s laboratory in 1954 as an in... Read More
Every day, millions of microorganisms reach Spain from the Sahara Desert and the Sahel region -- by flying. Louis Pasteur demonstrated back in 1861 that germs can move through the air, but it was only recently discovered that bacteria, fungi and viruses can travel thousands of kilometers stuck o...

Prospecting for new drugs in the genes of common bacteria could yield a "treasure trove" of therapeutic compounds, an expert has said.
Eriko Takano's team of bug experts already discovered a promising new antibiotic using the "genome mining" approach.
The drug was extracted from the soil b... Read More
Chemists at times look to plants, sea life and other natural sources for the basic ingredients needed to develop the next breakthrough medicine. Unfortunately, nature is not always willing to easily part with its secrets, forcing scientists to rely on sophisticated imaging technology—nuclear mag... Read More
For all the antibacterial products and other weapons in the war against germs, even the cleanest of us still carry about 10 bacterial cells for every human cell.
Most are harmless or even beneficial. Indeed, some scientists believe that the loss of friendly organisms in recent years could be ... Read More
Fears were growing Monday for up to 2.5 million people affected by Pakistan's worst floods in 80 years amid outbreaks of disease after monsoon rains killed more than 1,300 people.
Unprecedented rains triggered floods and landslides, sweeping away thousands of homes and devastating farmland in... Read More
