Scientists have cracked a 35-year-old mystery about the workings of the natural motors that are serving as models for development of a futuristic genre of synthetic nanomotors that pump therapeutic DNA, RNA or drugs into individual diseased cells. Their report revealing the innermost mechanisms ... Read More
Fat worms confirm that researchers from Michigan State University have successfully engineered a plant with oily leaves – a feat that could enhance biofuel production as well as lead to improved animal feeds.
The results, published in the current issue of The Plant Cell, the journal of the ... Read More
In the celebrated novel The Rebel Angels, the famed Canadian author Robertson Davies mentions Ozias Froats, a fictional professor potentially on his way to a Nobel Prize for discovering that everyone’s feces reflect the maker’s personality. He did not have today’s ready recourse to metagenomics ... Read More
Although the flu appears to be leveling off in the East, South and Midwest, numbers are still rising in the Southwest and Northwest, the Centers for Disease Control and Prevention reported.
The flu is widespread now in Washington state, said Donn Moyer of the Washington State Department of He... Read More
There’s no question that variation in size and shape has conferred selective advantages over the course of evolutionary time. One of the most obvious examples is the long neck and legs of the giraffe, which allow it to snatch foliage that is unreachable by vertically challenged competitors. The ... Read More
The microbial population in the air of the New York City subway system is nearly identical to that of ambient air on the city streets. This research, published ahead of print in the journal Applied and Environmental Microbiology, establishes an important baseline, should it become necessary to m... Read More
In a recent study published in PNAS, Houry and collaborators used time-lapse microscopy to monitor the biofilms formed by the bacterium Bacillus thuringiensis and noted that a small subset (0.1 to 1%) of all the cells in the biofilm were motile. The rest of the cells were sessile and immobile ex... Read More
Nearly 6% of lung cancer tissue samples from non-smokers show signs that HPV may have triggered the tumors. A common virus known to cause cervical and head and neck cancers may also trigger some cases of lung cancer, according to new research presented by Fox Chase Cancer Center at the AACR Ann...

In its native state, according to the CDC, the H5N1 flu virus is highly contagious and is especially deadly to birds. Fortunately, few people have contracted this strain of flu as it's quite deadly in people as well. Luckily, there have been very few cases of transmission of the virus between pe... Read More
Two studies of malnourished children offer the first major new scientific findings in a decade about the causes and treatment of severe malnutrition, which affects more than 20 million children around the world and contributes to the deaths of more than a million a year. Merely giving children a... Read More
Efavirenz (tradenames: Sustiva, Stocrin) is an antiretroviral (ARV) drug commonly used to treat HIV. Its popularity as a medication, alone or more commonly in combination with other HIV medications (tradename: Atripla), is due to its superior effectiveness in suppressing replication of the virus...

Five people in Saudi Arabia have died from a Sars-like virus and two more are seriously ill, officials say. The seven cases were all from al-Ahsa governorate in the east of the country, the Saudi news agency SPA said citing health officials. The novel coronavirus (NCoV) causes pneumonia and some...

Researchers have uncovered details of a mechanism that bacteria use to avoid the effects of antibiotics, which could pave the way for developing new drugs to counteract antibiotic resistance.
The discovery, from researchers at Durham University and the University of Birmingham, gives the firs... Read More
A synthetic version of the Schmallenberg virus has been made in the laboratory by Scottish scientists. The research raises hopes for developing a vaccine for the livestock disease, which causes lambs and calves to be stillborn. Schmallenberg virus (SBV) was discovered little more than a year ago...

A large-scale study of a biomedical intervention that potentially offers novel options for women to protect themselves from HIV infection has, to the surprise of many researchers, failed. But the results say more about the participants’ behavior than the effectiveness of the products being teste... Read More
Bacteria are all over us, inside and out. Jiri Hulcr recently found 1,458 species of bacteria "new to science" in a small sample of human belly buttons. What we know about our little passengers and how they affect our bodies is dwarfed by what we do not. That can be disconcerting to think about,... Read More
Pili are hair like appendages that are found on the outer membrane of bacteria. They are important for bacteria to attach to solid surfaces, are used as an apparatus in transfer of DNA from one cell to another, as well as twitching motility, and cell-cell adhesion.
In 2011 a group of scientist ... Read More
Seeing the mosquito-transmitted chikungunya virus pathogen at very high resolution while it’s bound to antibodies could lead to vaccines for the disease. The infection causes symptoms similar to dengue fever, followed by a prolonged disease that affects the joints and causes severe arthritis. In... Read More
