Mycorrhizal fungi live in the roots of host plants, where they exchange sugars that plants produce by photosynthesis for mineral nutrients that fungi absorb from the soil. They include some of the most conspicuous forest mushrooms, including the iconic, flaming red “fly agaric,” Amanita muscaria... Read More
An experimental compound empowers an enzyme to help process acetaldehyde, a toxic metabolite of alcohol, according to new research supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA). The findings, now online in the Proceedings of the National Academy of Sciences (PNAS), ... Read More

Caring for People Infected with Ebola: Stories from the Frontlines
Narrative Inquiry in Bioethics will publish a collection of personal stories from individuals who have been at the frontlines of healthcare for Ebola patients—whether as healthcare workers, family caregivers,... Read More
While it’s easy to think about mosquitoes as a mere portal for shuttling malaria and other diseases from one person to another, the insects have their own immune response to infection.
After sucking down a blood meal, mosquitoes ramp up production of immune system proteins to fight off potent... Read More
When exposed to nitrogen fertilizer over a period of years, nitrogen-fixing bacteria called rhizobia evolve to become less beneficial to legumes – the plants they normally serve, researchers report in a new study.
These findings, reported in the journal Evolution, may be of little interest to... Read More
Most would choose the cuddly gerbil over the much-maligned rat. But the latter's bad reputation may not be fully deserved. Central Asian rodents, not rats, prospering under warm variations in climate, could have been to blame for the arrival of the Black Death in Europe in 1347 and for repeated ... Read More
If ever there was proof of the power of small things, surely this is it. Last year, came the suggestion that sponges transformed Earth's deep oceans 750 million years ago, turning them into an oxygen-rich haven for life. Now it seems tiny bacteria living inside the sponges also played a part in ... Read More
This episode: Bacteria living in plants could help plants clean up cancer-causing pollutants!

Malaria: shaking chills & fever (followed by sweats, not specifically mentioned in this case), is a characteristic of malaria that is unforgettable once one has had it (I had malaria four times).
Thick blood smears is de rigueur.
Vincent, Dickson, and Daniel present a new case study, and discuss the effect of chronic malaria infection on wild warbler life span and telomere degradation.
In the northeastern United States, warmer spring temperatures are leading to shifts in the emergence of the blacklegged ticks that carry Lyme disease and other tick-borne pathogens. At the same time, milder weather is allowing ticks to spread into new geographic regions. Findings were published ... Read More
Henry Ford Hospital researchers say that breastfeeding and other factors influence a baby’s immune system development and susceptibility to allergies and asthma by what’s in their gut.
The striking findings from a series of studies further advance the so-called hygiene hypothesis theory that ... Read More
Bacteria may not have brains, but they do have memories, at least when it comes to viruses that attack them. Many bacteria have a molecular immune system which allows these microbes to capture and retain pieces of viral DNA that they have encountered in the past, in order to recognize and destro...

Until now, the standard way to check for Ebola in the region was to use the nucleic acid test, which works by identifying the genetic materials of the virus from a blood sample. Yet the test requires a full lab to succeed, and it takes between 12 to 24 hours to process the results. In comparison... Read More
Infections lurking on the margins of civilization are becoming more likely to cause outbreaks as the climate changes, researchers say. Ravens, rodents and rattlesnakes are moving to new locales as rainfall and temperatures shift over time (ClimateWire, Dec. 14, 2011).

On May 30, 2012 Brianna Dannen, Public Health Nurse at the Clark County Health District (CCHD), received a call from Bob Williamson at Clark College. Mr. Williamson called to report that a child of a Clark College student enrolled in a microbiology class, BIOL&260, taught by Travis Kibota was i... Read More
The specific strain of HIV that a person first contracts can have a lasting impact on how the virus disrupts his or her immune system, say researchers.
“This may have important implications for cure strategies aimed at eliminating the viral reservoir, as individuals infected with low replicat... Read More
The first results from a trial of a candidate Ebola vaccine at Oxford University suggest the vaccine has an acceptable safety profile at the doses tested, and is able to generate an immune response.
'The vaccine was well tolerated. Its safety profile is pretty much as we had hoped,' said Prof... Read More
Scientists have shown that airport screening for disease will often miss half or more of infected travelers, but can be improved by customizing to pathogens. The findings are published in the journal eLife.
They present options for policy makers; for example whether resources would be better ... Read More
