Understanding Cicadas and their Bacterial Symbionts

How do cicadas gather the nutrients they need to survive, despite their low-nutrient diet? John McCutcheon, a molecular biologist at the University of Arizona, says that cicadas supplement their diet by maintaining complicated relationships with two species of specialized bacteria that live insi...

Half of Connecticut's Honey Bees Infected by American Foulbrood

The AP is reporting 10% of Connecticut's registered beehive population is seriously infected with the American foulbrood bacterium, Paenibacillus larva, another 40% of hives show a low level exposure in their brood chambers, where eggs develop into adults.

Experts say the findings are troubl... Read More

A Biochemical Way to Reduce Drug Side Effects?

Despite what the overcrowded, overpriced shelves of your pharmacy might suggest, pharmaceutical companies struggle to find new drugs these days. The low-hanging fruit is long gone, and the main discovery method that served so well in past decades is generating far fewer hits today. But a fresh s... Read More

Routine tests turn up avian flu in Minnesota turkeys

Thousands of turkeys in Minnesota have been quarantined after a strain of avian flu (H7N9) was found at a poultry farm there. Experts say that the strain is markedly less virulent than H5N1, the Asian strain that has caused more than 250 human deaths and millions of poultry deaths.

"It would ... Read More

Gov't reassures schools on staying open with flu

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

Bacteria May Be Connected to Colic

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

Leukemia Cells Flash Fake Protein "ID" to Dupe the Immune System

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

Genomic "signature" in blood can reveal exposure to colds or influenza, even before symptoms appear

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

Finding the key to strengthening the immune response to chronic infections

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...

Pinhead-size worms + robot = new antibiotics

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

”Build a Bacterium” Scavenger Hunt

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

Dog suspected source of China plague

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

Cyber Exploring The 'Ecosystems' Of Influenzas

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
