Wallace L. Pannier, a germ warfare scientist whose top-secret projects included a mock attack on the New York subway with powdered bacteria in 1966, has died of respiratory failure and other natural causes, his widow said.
He died Thursday in Frederick. He was 81. Read More

The federal government is advising schools they don't need to close their doors this fall just because a few students come down with swine flu.
Homeland Security Secretary Janet Napolitano said Friday that only schools with high numbers of students getting the new flu should consider closing ... Read More
A bacterium normally found in the mouth, skin and intestines might play a role in the still-mysterious cause of colic in babies, a new study says. Researchers found the bacterium Klebsiella along with gut inflammation in the intestines of all babies in their study who had colic, a condition char... Read More
Bone marrow continually makes blood stem cells, which turn into new blood cells to replace spent ones, but the process is not perfect: Some blood stem cells can develop into abnormal versions, although the immune system usually stamps them out. In acute myeloid leukemia, however, the immune syst... Read More

Scientists have identified a genomic "signature" in circulating blood that reveals exposure to common upper respiratory viruses, like the cold or flu, even before symptoms appear.
The tell-tale viral signature reflects a set of subtle but robust changes in genes that are activated as the bod... Read More
A team of researchers from The Wistar Institute has identified a protein that could serve as a target for reprogramming immune system cells exhausted by exposure to chronic viral infection into more effective "soldiers" against certain viruses like HIV, hepatitis C, and hepatitis B, as well as s...

Scientists in Massachusetts are describing successful use of a test that enlists pinhead-sized worms in efforts to discover badly needed new antibiotics. Thestudy appears in ACS' Chemical Biology.
From the abstract:
The nematode Caenorhabditis elegans is a unique whole animal model system ... Read More
In this activity, each student is provided with a worksheet and three index cards. Each card indicates a different cell part (e.g. LPS, capsule, DNA). Students are placed in small groups and receive a written scenario regarding a bacterium with a certain goal it must carry out. They must work t... Read More
Can anyone please explain why so many infectious diseases ("Spanish" influenza of the 1910's, SARS, the bubonic plague of the middle ages, etc.) seem to have their origins in China/that area of the world? Read More
Predicting the infection patterns of influenzas requires tracking both the ecology and the evolution of the fast-morphing viruses that cause them, said a Duke University researcher who enlists computers to model such changes.
A single mutation can put a flu virus on a new-enough path to re-in... Read More

In a paper published in Nature, a research team from the University of North Carolina described the full genome structure of HIV-1 for the first time.
"The researchers used a high-throughput method called "selective 2'-hydroxyl acylation analyzed by primer extension" (SHAPE) to glean structur... Read More
Tonight the Seattle Sounders FC, a Major League Soccer team, take the field against FC Barcelona, soccer's world champion. The real enemy for both teams, however, is malaria. Joining forces with the Bill & Melinda Gates Foundation, the teams have planned a special match that includes messages ab... Read More
From swine flu to pneumonic plague - with E.coli in the mix - microbes have been making the headlines. Are they getting the better of us?
Whether its flesh-eating necrotising fasciitis or equine morbillivirus, in which the sufferer essentially drowns in fluid leaking from the lungs, infection... Read More
Nestled within the new Pacific Remote Islands Marine Monument lies Palmyra Atoll, one of the last pristine coral reefs left on the planet some 960 nautical miles south of Hawaii. Or near pristine. In 1991, a 100-foot longline fishing ship—the "Hui Feng No. 1"—foundered on the reef under mysterio... Read More
