Bacterial propulsion systems are intriguing for nanotechnology researchers because nature has already solved most of the problems that they are still struggling with in designing molecular motors and other self-sustained nanoscale actuating systems. Indeed, it has turned out to be very challengi... Read More
New findings by a University of Maryland-led team of scientists indicate that a genetically engineered fungus carrying genes for a human anti-malarial antibody or a scorpion anti-malarial toxin could be a highly effective, specific and environmentally friendly tool for combating malaria, at a ti...

Between 19 January and 17 February 2011, 10 cases of measles (eight laboratory-confirmed and two probable) were reported in Oslo with the majority of cases in a mainly unvaccinated immigrant community. Of these, two cases were identified outside the immigrant community, in Norwegian children. Read More
Half of men in the general population may be infected with human papillomavirus or HPV, the human wart virus that causes cervical and other cancers, strengthening the case for vaccinating boys against HPV, U.S. researchers said on Monday.
U.S. vaccine advisers have been weighing whether boys ... Read More
Multiple viruses have been linked to ME/CFS suggesting that multiple pathogens cause the same disease or several diseases with core signs and symptoms. Or if you are on Team XMRV /MuLV - a retrovirus could be the mastermind. No matter how you slice it in science, questions beget theories which... Read More
This thin-section transmission electron micrograph (TEM) revealed the ultrastructural appearance of a single virus particle, or “virion”, of measles virus. The measles virus is a paramyxovirus, of the genus Morbillivirus. It is 100-200 nm in diameter, with a core of single-stranded RNA, and is c... Read More
This negatively-stained transmission electron micrograph (TEM) revealed the presence of Rubella virus virions, as they were in the process of budding from the host cell surface to be freed into the host’s system, thereby, producing an enveloped virus particle, which means that after budding, the...

Researchers identified a monoclonal antibody (MAB) that neutralizes West Nile virus (WNV) by binding and crosslinking viral surface proteins that are needed to infect host cells. "The antibody crosslinking causes the virus to become rigid, and this rigidity prevents conformational changes and lo... Read More
Although, in the majority of cases, the localized presence of Neisseria meningitidis in the throat has no consequence, it can sometimes lead to meningitis or septicaemia. The seriousness of these two infections is driving researchers from around the world to improve their understanding of the mo... Read More
Bacteria in the human gut may not just be helping digest food but also could be exerting some level of control over the metabolic functions of other organs, like the liver, according to research published this week in the online journal mBio®. These findings offer new understanding of the symbio... Read More
Los Angeles County public health officials have identified Legionella bacteria, which causes Legionnaires’ disease, at a water source at the Playboy Mansion in Los Angeles in its investigation of the source of illness that sickened people after a fundraiser earlier this month.
Public health o... Read More
A team involving University of Tennessee, Knoxville, researchers has conducted the first-ever genetic sequencing of a harmful algal bloom (HAB) species, cracking the genome of the micro-organism responsible for the Eastern Seaboard’s notorious brown tides.

Imagine going to your doctor for a routine checkup and the phlebotomist takes a few blood samples for lab work. Three days later, the doctor's office calls and asks you to come back because they need to get another sample for testing. Wondering if something is terribly wrong, you ask "why?" sinc... Read More
Preventing infection in a wound may depend less on choosing the right antibiotic than on simply keeping it clean.
Researchers writing in the March issue of Pediatrics studied 200 children ages 6 months to 18 years. Each had a skin infection (generally from allergies, diaper rash or eczema), ... Read More
Researchers at the University of Illinois at Chicago have discovered a signaling mechanism in the bacterial ribosome that detects proteins that activate genes for antibiotic resistance.
"The ribosome is one of the most complex molecular machines in the cell," said Alexander Mankin, UIC profes... Read More
The latest beauty craze—fish pedicures—offered in salons and spas across the world have raised serious health concerns.
British experts are worried that the trend that is sweeping the country could spread infection and disease, reports the Daily Mail.

I need a beer. It's a phrase uttered by many contemporary workers after a long day at the office, but new research shows that ancient cultures were probably using the alcoholic beverage to treat much more than the stress of everyday life. Anthropologists have found that thousands of years befo... Read More
Any woman who has ever done battle with a urinary tract infection will vouch for the notion that the human body can harbor both good germs and bad germs. Bad bacteria in the bladder can turn life into a series of miserable trips to the bathroom. But at the same time, good bacteria can keep yeast... Read More
New research enhances the current knowledge of how human immunodeficiency virus type-1 (HIV-1), which causes AIDS, controls the cell cycle of cells that it infects. The new findings may shed light on how the virus reactivates after entering a dormant state, called latency.

Passengers aboard a Southwest Airlines flight from Baltimore to Denver and San Diego on Feb. 22 are in danger of contracting measles because one of the passengers was infected with the virus, San Diego County health officials said Saturday.
Passengers are being contacted by health workers and... Read More
