Attachment of several treponemes to testicular cell membranes 22 hours post-infection. Note the orientation of the treponemes mediated by their tapered ends and apparent disk-like organelle Read More
Although the swine flu outbreak of 2009 is still in full swing, this global influenza epidemic, the fourth in 100 years, is already teaching scientists valuable lessons about pandemics past, those that might have been and those that still might be. Evidence accumulated this summer indicates that... Read More
A search through decades-old frozen infant stool samples has yielded rich dividends for scientists from the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health. The team customized a laboratory technique to screen thousands of samples for noro... Read More
Knowing what causes a disease may not make it easier to control and contain infection, but understanding how humans become infected and where the pathogens live may improve control. A National Science Foundation grant for $1.5 million over five years will allow an international team of researche... Read More
If you have ever taken a long road trip, the windshield of your car will inevitably be splattered with bugs by the time you arrive at your destination. Could the DNA left behind be used to estimate the diversity of insects in the region? In a study published online in Genome Research, scientists... Read More
Cheaters may prosper in the short term, but over time they seem doomed to fail, at least in the microscopic world of amoebas where natural selection favors the noble.
But why? Shouldn't "survival of the fittest" give the sneaky cheaters an edge? Not necessarily, as it turns out amoebas that c... Read More
Leishmania is a deadly parasitic disease that affects over 12 million people worldwide, with more than 2 million new cases reported every year. Until recently, scientists were unsure exactly how the parasite survives inside human cells. That mystery has now been solved according to a new study p... Read More
More so than many illnesses, chronic fatigue syndrome (CFS) frustrates those who suffer from it and those close to them, due to its nebulous assembly of symptoms, along with continued controversies over its etiology, diagnosis, treatment and even its nomenclature. Now, the discovery of a familia... Read More

Australian scientists have found that the bacterium Cupriavidus metallidurans catalyses the biomineralisation of gold by transforming toxic gold compounds to their metallic form using active cellular mechanism.
Researchers reported the presence of bacteria on gold surfaces but have never clea... Read More

Companies that offer analyses of future health risks based on basic genetic tests should be more transparent about the limitations of their predictions, says genomics pioneer Craig Venter.
He and four colleagues have proposed guidelines for the industry after assessing the results of scans of... Read More
THE weakness in Achilles' heel didn't pose much of a problem until it came into contact with Paris's arrow - at which point it killed him. Now a range of tumours are meeting a similar fate thanks to drugs that turn otherwise insignificant gaps in their defences into fatal flaws.
A pioneering ... Read More
Thermo Fisher Scientific said today that it plans to close its manufacturing plant in Dubuque, Iowa, by September 2010 and will cut the 350 jobs at the facility over coming year.
The plant closing comes just days after the company announced it plans to shut down a plant in Hudson, NH, a move ... Read More
A new sequencing study by Canadian researchers suggests that primary breast cancers acquire significant numbers of new mutations in their coding regions as they progress towards metastasis — a characteristic that underscores the importance of analyzing cancers at different stages, the researcher...

In recent years scientists have made synthetic versions of key parts of the cell, such as chromosomes and ribosomes. Now researchers have developed the first working artificial prototype of an “organ” of a human cell—the Golgi apparatus.
Made up of a network of sacs piled together like a stac... Read More
Microscopes have been around for some 400 years, and today they are even accessible via customized cell phones. The act of peering into a microscope of any power can open a whole world of life and beauty that exists right under (or in) our noses. And to capture that rare view for reproduction ca... Read More
Swiss pharmaceutical company Novartis AG (NVS) said Thursday it has gained exclusive worldwide rights to market what could become the first once-a-day broad-spectrum antibiotic that can be given as a tablet or intravenously to treat infections caused by drug-resistant bacteria.
The drug candi... Read More
