Being jolted awake every morning by an alarm clock is plenty annoying, but at least that alarm doesn’t actually live in your body.
The Hawaiian bobtail squid (Euprymna scolopes) has an internal alarm clock that’s run by a species of glowing bacteria known as Vibrio fischeri. This bacterium an... Read More
If one were to ask, “What happens when Salmonella infects the gut?” it might not be obvious that you’d also need to ask, “What time is it?” But indeed you’d need to know the latter to appropriately address the former. An invading Salmonella, intent on setting up camp, is trying to pitch its tent... Read More
High atop a platform inside a clean room at the European Space Agency’s (ESA) launch site in South America, scientists painstakingly searched for microbes near the Ariane 5 rocket due to launch the Herschel space telescope in May 2009. Only very unusual organisms can survive the repeated sterili... Read More
Whooping cough among adults 50 or older is much more common than generally thought, and the incidence appears to be rising, a researcher said here.
A mathematical model based on medical practice and laboratory databases suggested that pertussis among adults ages 50 through 64 more than double... Read More
On May 8th JoVE will publish research that demonstrates how a biosensor can detect antibiotic resistance in bacteria. This new technology is a preliminary step in identifying and fighting superbugs, a major public health concern that has led to more deaths than AIDS in the United States in recen... Read More
Some heavy metals are required in trace amounts for the survival of living organisms, however at higher concentrations these metals can be incredibly toxic. In Europe, the elements of highest concern are arsenic, cadmium, cobalt, chromium, copper, mercury, manganese, nickel, lead, tin, and thall... Read More
Based on FluNet reporting (as of 18 October 2013, 11:35 UTC), during weeks 40 to 41 (29 September 2013 to 12 October 2013), National Influenza Centres (NICs) and other national influenza laboratories from 81 countries, areas or territories reported data. The WHO GISRS laboratories tested more th... Read More
Usman, who limps on a leg bowed by the polio he caught as a child, made sure that his first three children were protected from the disease, but he turned away vaccinators when his youngest was born.
He was furious that the Central Intelligence Agency, in its hunt for Osama bin Laden, had stag... Read More
Most microbial researchers grow their cells in petri-dishes to study how they respond to stress and damaging conditions. But, with the support of funding from NASA, researchers in LSU's Department of Biological Sciences tried something almost unheard of: studying microbial survival in ice to und... Read More
The tiny thymus teaches the immune system to ignore the teeming, foreign bacteria in the gut that helps you digest and absorb food, researchers say.
When immune cells recognize essential gut bacteria as foreign, inflammatory bowel disease such as ulcerative colitis and Crohn's disease can be ... Read More
Researchers studied 10 different cyanobacteria to identify their secondary metabolites (compounds produced during normal cellular metabolism not directly involved in cell growth, that may play an important role in interactions outside the cell) and the genes linked to those molecules.
Underst... Read More
Every day we see animals migrating through the air, across plains, and in the oceans, in beautifully coordinated patterns; starlings flock together in the thousands while sardines swim together in enormous shoals. These social behaviors are important in allowing animals to socialize, avoid preda... Read More
Keeping cancer cells from entering a state of cellular sleep makes cancer drugs more effective and lowers the chance of cancer recurrence, report researchers.
The findings, which will be published in the August 15 issue of the journal Cancer Research and are available online, are the first to... Read More
Bacteria, with their ability to grow, develop and sustain themselves in a variety of conditions, could be the miniature powerhouses that could drive us to a clean energy future.
Researchers at Arizona State University’s Biodesign Institute are studying certain bacteria’s ability to produce el... Read More
In a hot, steamy lava cave on the Kilauea Caldera in Hawai’i, microbiologists collecting samples from a dripping purple mat on the cave floor have found a new species that could reveal how bacteria that spit oxygen into the atmosphere millions of years ago evolved.

Studying bacteria from the Baltic Sea, UA researchers have discovered an entire array of previously unknown viruses that barely resemble any of the known bacteria-infecting viruses.
Researchers of the University of Arizona's Tucson Marine Phage Lab have discovered a dozen new types of unknown... Read More
Mealybugs only eat plant sap, but sap doesn't contain all the essential amino acids the insects need to survive. Luckily, the bugs have a symbiotic relationship with two species of bacteria -- one living inside the other in a situation unique to known biology -- to manufacture the nutrients sap ... Read More
Human migrations—from the prehistoric epoch to the present day—have extended cultures across the globe. With these travelers have come unwanted stowaways: mosquito-borne parasites belonging to the Plasmodium species— a group responsible for malaria worldwide.

A Dixieland band player who didn’t clean his clarinet for 30 years is recovering from a year-long allergic reaction caused by fungus that grew inside the reed instrument, experts said.
The 68-year-old unidentified Atlanta man came down with an intractable case of “saxophone lung,” an actual c... Read More
In order to overcome resistance to antifungal variety of pathogenic fungi and yeast, researchers from the University of Alicante have developed a novel and efficient antifungal composition with pharmacological applications in agriculture and food industry, among others.
The composition, deve... Read More
