Researchers have found evolved pertussis, as whooping cough is scientifically known, in Finland, France, Italy, Japan and the U.S. As we previously reported, the evolved bacteria don't seem to be more dangerous than their predecessors. Nevertheless, the U.S. Centers for Disease Control and Preve... Read More
A new study that analyzed about 80,000 gene sequences from flu viruses has revealed that birds may have had some help from horses in spreading the virus that eventually killed 50 million to 100 million people in the influenza pandemic in 1918. Two viral genes may have circulated for years before... Read More
Scientists are testing vaginal pessaries containing 'good' probiotic bacteria for the treatment of vaginal thrush. The research shows that this approach is likely to be a viable alternative to using precious antimicrobial drugs.

Owls are the natural predators of the rats carrying the deadly hantavirus, the Santiago Times newspaper reports. Long-tailed pygmy rice rats transmit the virus to humans as they come into contact with campers in the forest, while foraging for bamboo. But forest fires during Chile's summer months... Read More
There are many elements that go into making a great lecture, but the most important one is to lose the notes. If you are giving lectures in a course at any level, the worst practice you can engage in is to rely on notes. This behavior is problematic for several reasons. You will not properly kno... Read More
For my medical microbiology course at Kutztown University of Pennsylvania we were asked to take a sample from our nose. Using a sterile cotton swab, a sample was taken from a nostril and then spread onto the Mannitol Salt Agar plate supplied. The plate was incubated at 37 degrees Celsius, then e... Read More
The study confirms "the existence of an offensive biological warfare research programme in Nazi Germany." In January of 1942, Heinrich Himmler ordered the opening of an entomological laboratory in the Dachau concentration camp in southeastern Germany. But why? The stated purpose of the institut...

OpenBiome, a company based in Cambridge, Mass., has opened a facility that collects stool samples from healthy, pre-screened individuals. It then processes those "donations" and readies them for shipment to hospitals, where they are put into the colons of people with the deadly gut infection Cl... Read More
Gareth Thomas, founder of Berkeley Lab’s National Center for Electron Microscopy (NCEM) and one of the world’s foremost experts on electron microscopy, passed away on February 7. He was 81.

Researchers have tested a preliminary form of a vaccine against the disease, which is spread by the bite of the mosquito and kills more than 600,000 people each year. Until now, developing malaria vaccines has been challenging. A vaccine must incorporate key proteins from the malaria parasites, ... Read More
A University of California, Riverside assistant professor of engineering is among a group of researchers that have made important discoveries regarding the behavior of a synthetic molecular oscillator, which could serve as a timekeeping device to control artificial cells. Read More
In addition to storing films, optical discs can be used to detect microorganisms, toxins, allergens and tumoral biomarkers. Blu-ray technology has allowed researchers to develop a way to find out if a sample contains Salmonella or toxic substances. This simple and cheap analytical system may be ... Read More
North Carolina could be looking at a record year for flu deaths, or at the very least a near record year. North Carolina health officials released new flu numbers Friday, saying seven more people have died in the last week. That brings the total number of deaths from flu-related complications th...

In this blog post, I show a science-cartoon by the great "Beatrice the Biologist" that illustrates an important point in my freshman introductory cell and molecular biology course: no matter how tired we might be, we are incredibly busy on a cellular level! Beatrice is a fine artist who underst... Read More
The H1N1 virus responsible for the 2009 global pandemic is back. State health officials from across the country say the resurgence is resulting in a dramatic rise in flu deaths in young and middle-aged adults and in children this season.
While the reported death tolls so far are only a fracti... Read More
Dr. Lenny Tender, research chemist at the Naval Research Laboratory (NRL), has co-invented a microbial fuel cell that persistently generates electrical power in marine environments.The fuel cell draws electricity from the sea floor, creating an interface between the sediment on the bottom of a m...

Tularemia is endemic in the northeastern United States, and is considered to be a risk to biosecurity -- much like anthrax or smallpox -- because it has already been weaponized in various regions of the world.
At the 58th Annual Biophysical Society Meeting, which started Saturday and continue... Read More
Scientists have deciphered the 3-D structure of a protein that confers antibiotic resistance from one of the most worrisome disease agents: a strain of bacteria called methicillin-resistant Staphylococcus aureus (MRSA), which can cause skin and other infections. The team's findings may be an imp... Read More
Plop living, swimming bacteria into a novel water-based, nontoxic liquid crystal and a new physics takes over. The dynamic interaction of the bacteria with the liquid crystal creates a novel form of soft matter: living liquid crystal.
The new type of active material, which holds promise for i... Read More
Ankyrin (ANK) repeats are one of the most common amino acid sequence motifs that mediate interactions between proteins of myriad sizes, shapes and functions. We assess their widespread abundance in Bacteria and Archaea for the first time and demonstrate in Bacteria that lifestyle, rather than ph... Read More
