Individuals with a psychiatric disorder involving recurrent bouts of extreme, impulsive anger-road rage, for example-are more than twice as likely to have been exposed to a common parasite than healthy individuals with no psychiatric diagnosis.

Malaria affects close to 500 million people every year, but we're not the only ones--different species of malaria parasite can infect birds, bats, and other mammals too. A Field Museum study published in Molecular Phylogenetics and Evolution reveals a new take on the evolution of different malaria species and contributes to the ongoing search for the origins of malaria in humans. "We can't begin to understand how malaria spread to humans until we understand its evolutionary history," explained lead author Holly Lutz, a PhD candidate at Cornell University and a longtime affiliate of The Field Museum. "In learning about its past, we may be better able to understand the effects it has on us."

A group of researchers at the University of Texas at El Paso is working on making it cheaper, faster and easier to test for meningitis and pertussis. Dr. XiuJun “James” Li, assistant professor of chemistry, and Dr. Delfina C. Domínguez, professor of clinical laboratory sciences, have joined efforts to produce a paper-based biochip that can be used in schools, clinics and developing nations.

More cities than previously assumed could soon grapple with the Zika virus if two species of mosquitos are found to be equally effective carriers of the disease, a University of Texas at Austin disease ecologist and his colleagues argue in the current edition of The Lancet Infectious Diseases.

Mosquitoes are deadly efficient at spreading disease. Despite vaccines and efforts to eradicate the pesky insects, they continue to infect humans with feared diseases like Zika virus, malaria and West Nile virus. Gaining the upper hand on mosquitoes requires speed. Their life cycle is typically two weeks or less and they need only warm weather and standing water to breed.

Drug-resistant bacteria are fast becoming one of the big worries of the 21st century. Now researchers at the University of Copenhagen have discovered a previously unknown weakness -- an Achilles' heel of bacteria. Their discovery, a crucial step in bacteria's energy metabolism, may be the first step in developing an entirely novel form of antibiotics.

A University of Saskatchewan (U of S) research team has discovered a way to prevent bacteria from developing resistance to antibiotics, potentially helping to blunt the edge of a looming threat to public health around the world.
