- The 'MIP-MAP' game: Indian bug is the ancestor of Crohn's disease pathogen
10-02-2007 · EurekAlert!
An Indian team of researchers led by Seyed E. Hasnain of the Institute of Life Sciences, University of Hyderabad, India has found that a seemingly unknown mycobacterial organism Mycobacterium indicus pranii could be the earliest ancestor of the 'generalist' branch of mycobacterial pathogens. The 'generalist' bacteria infect anything from cockroaches to human and are capable of surviving in soil and water as against human adapted 'specialists' such as tubercle and leprosy bacilli.

- Transparent zebrafish help researchers track breast cancer
10-22-2007 · EurekAlert!
What if doctors could peer through a patient's skin and see a cancer tumor growing? They'd be able to study how tumor cells migrate: how they look, how they interact with the blood system to find nourishment to grow and spread through the body. Scientists at the UCSD School of Medicine can't look through human skin. But a small, tropical minnow fish common to aquariums has given researchers a window for viewing live, human cancer cells in action.

- Using carbon nanotubes to seek and destroy anthrax toxin and other harmful proteins
12-10-2007 · EurekAlert!
Researchers at Rensselaer Polytechnic Institute have developed a new way to seek out specific proteins, including dangerous proteins such as anthrax toxin, and render them harmless using nothing but light. The technique lends itself to the creation of new antibacterial and antimicrobial films to help curb the spread of germs, and also holds promise for new methods of seeking out and killing tumors in the human body.

- Genetic map offers new tool for malaria research
12-10-2006 · EurekAlert!
An international research team has created a genome-wide map that charts the genetic variability of the human malaria parasite Plasmodium falciparum. The study reveals striking variation within the pathogen's genome, and lays the foundation for dissecting the functions of important parasite genes and for tracing the global spread of malaria. Already, the tool has helped to unearth novel genes that may underlie resistance to current drugs against malaria.

- Spaceflight shown to alter ability of bacteria to cause disease
09-24-2007 · EurekAlert!
Space flight has been shown to have a profound impact on human physiology as the body adapts to zero gravity environments. Now, a new study led by researchers from the Biodesign Institute at Arizona State University has shown that the tiniest passengers flown in space -- microbes -- can be equally affected by spaceflight, making them more infectious pathogens.

- Targeting gut bugs could revolutionize future drugs, say researcher
02-01-2008 · EurekAlert!
Revolutionary new ways to tackle certain diseases could be provided by creating drugs which change the bugs in people's guts, according to a new article. Trillions of bugs known as gut microbes live symbiotically in the human gut. They play a key role in many of the processes that take place inside the body. Different people have different types of gut microbes living inside them and abnormalities in some types have recently been linked to diseases such as diabetes and obesity.

- A genetic 'gang of 4' drives spread of breast cancer
04-11-2007 · EurekAlert!
Studies of human tumor cells implanted in mice have shown that the abnormal activation of four genes drives the spread of breast cancer to the lungs. The new studies by Howard Hughes Medical Institute researchers reveal that the aberrant genes work together to promote the growth of primary breast tumors. Cooperation among the four genes also enables cancerous cells to escape into the bloodstream and penetrate through blood vessels into lung tissues.

- Inherited individual variations influence patterns of gene shuffling
01-31-2008 · EurekAlert!
The first large-scale, high-resolution study of human genetic recombination has found remarkably high levels of individual variation in genetic exchange, the process by which parents pass on a mosaic-like mixture of their genes. The high-resolution enables the researchers to map out the precise location of where these genetic exchanges occur and assess the differences in recombination rates between individuals.

- Map is first to track global human influences on ocean ecosystems
02-14-2008 · EurekAlert!
The first global map of human influences on marine ecosystems has been constructed by a team of researchers, including a Stanford University scientist among the principal investigators, by gathering and interpreting massive amounts of data from the professional literature and from researchers around the world. This study suggests that about 41 percent of oceans bear a serious human "footprint " and that few blue spots on our planet are likely pristine.
