Bacteria recognize antimicrobials, respond with counter-defenses

...ughout the food chain. Learning how this sometimes deadly organism fights back against the immune system may lead to treatments that get around bacterial resistance. Work in this area may also suggest ways other disease-causing, Gram-negative bacteria maintain a stronghold in the midst of the body's attemp...

Why do aneurysms form? New studies suggest leading role for white blood cells

...on of aorta before time runs out. But despite the deadly toll of this condition, called abdominal aortic aneurysm or AAA ("triple A"), experts know very little about why it happens. Now, a pair of papers from researchers at the University of Michigan Cardiovascular Center is shedding new light on the myste...

Several minute intermediate stage in virus-cell fusion discovered; opportunity for drug development

...hole, or pore, through which the virus unloads its deadly genetic cargo into the host cell does not open up right away; instead, a small pore can persist for several minutes before adopting its final size, or (in rare cases) closing permanently. This 'intermediate stage,' as the scientists describe this ti...

Researchers discover how malaria parasite disperses from red blood cells

...es of the parasite Plasmodium, the most common and deadly of which is Plasmodium falciparum. P. falciparum spends part of its life cycle in the salivary glands of mosquitoes and is transmitted to human beings through the bite of infected mosquitoes. The parasite infects red blood cells. Called a merozoit...

Global warming increases oyster sensitivity to pollution

Researchers report breakthrough against world’s deadliest viruses

...tecting monkeys against infection from these often deadly viruses. Monkeys are known to develop hemorrhagic fever symptoms that are similar to those observed in humans infected by these viruses. Demonstrating that these vaccines are safe and effective in monkeys is a promising indicator of their real poten...

Researchers develop gene therapy to reverse pulmonary arterial hypertension

...ments for pulmonary arterial hypertension (PAH)--a deadly form of high blood pressure in the pulmonary arteries caused by uncontrolled cell growth. Therapies are currently limited for a disease that can lead to heart failure and death within a few years. The researchers have shown that Survivin, a protein ...

Infectious disease expert warns of spread of Rocky Mountain spotted fever

...s may be the best means of curbing the potentially deadly impact of the disease, which can be effectively treated with specific antibiotics if caught early. "Rocky Mountain spotted fever is a dangerous and potentially fatal disease, unlike its more widespread cousin, Lyme disease, which is almost never fat...

UCLA scientists reveal how Nipah virus infects cells

UCLA scientists have discovered how the deadly Nipah virus infiltrates human cells to cause encephalitis. Designated as a potential bioterrorism agent by the National Biodefense Research Agenda, the virus exploits a protein essential to embryonic development to enter cells and launch its attack. ...

India's smoking gun: Dino-killing eruptions

...,000 years - fast enough to have possibly caused a deadly global climate shift. "Our working hypothesis is that the majority of the total volume of lava might have been erupted in only a few major events spread over only a small fraction of millennia," said Anne-Lise Chenet of the Laboratoire de Paleomagne...

Lactose intolerance linked to ancestral environment

"The implication is that harsh climates and dangerous diseases negatively impact dairy herding and geographi...

New partnership to clear landmines for African Elephants

...conflict that ended in 2002, landmines have formed deadly barriers for humans and wildlife in Kuando-Kubango Province. They prevent area residents from walking safely on their land or cultivating their fields. Similarly, the 130,000 elephants of northern Botswana cannot re-establish themselves in their his...

Tiny avalanche photodiodes target bioterrorism agents

...ted States in 2001 the threat of a larger and more deadly bioterrorism attack -- perhaps from smallpox, plague or tularemia -- became very real. But the ability to detect such biological agents and rapidly contain an attack is still being developed. In a significant finding, researchers at Northwestern Uni...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

In addition to the public health implications, Frank sees the parasite as a primitive link to modern eukaryotes and ...

Prescription pain patch abuse blamed for increase in deaths

...ns, but in some cases is being misused, often with deadly consequences. "Because the patch is a sustained release form of the drug, if one withdraws the 72 hours' worth of drug and uses it in a form that it wasn't designed to be used for, then it can rapidly result in death," said the study's lead research...

Purdue researchers find key to rice blast fungus

..., which is known as rice blast fungus, is the most deadly of the pathogens that attack rice, reducing yields by as much as 75 percent in infected areas. Learning how the fungus tricks rice's natural defenses against pathogens to penetrate the plant is an important part of controlling the disease, said Jin-R...

On a wing and a prayer - Alaska researchers seek clues to bird flu
