An innovative new diagnostic for Lyme disease
When researchers examined the mitochondrial DNA of Ötzi, a man entombed in ice high in the Tyrolean Alps some 5,300 years ago, they made a startling discovery. Secreted within the tangles of the ice man’s genetic code was evidence he’d…
New research predicts stability of mosquito-borne disease prevention
UNIVERSITY PARK, Pa.–To reduce transmission of dengue to humans, scientists have introduced Wolbachia bacteria to A. aegypti mosquitoes. Now a team of international researchers has found that Wolbachia’s ability to block virus transmission may be maintained by natural selection, alleviating…

New study, led by Penn Medicine and Paris Transplant Group, found French transplant centers are far
To stop mosquito-transmitted illnesses, pay attention to how humans behave: study
Targeting the mosquito population within a defined area is the primary way scientists and public health officials mitigate the spread of diseases caused by viruses like Zika, dengue fever, and West Nile. But researchers have discovered that evaluating how humans…
Exciting new vaccine targets killer disease TB
Australian medical researchers from the Centenary Institute and the University of Sydney have successfully developed and tested a new type of vaccine targeting tuberculosis (TB), the world’s top infectious disease killer. Reported in the ‘ Journal of Medicinal Chemistry ‘,…
Researcher works to understand how gonorrhea develops resistance to antibiotics
Steadily and relentlessly, the bacterium that causes gonorrhea has slipped past medicine’s defenses, acquiring resistance to once-reliable drugs, including penicillin, tetracycline, and ciprofloxacin. These former stalwarts are no longer used to treat the sexually transmitted disease. In 2010, after some…
