(Thomas Jefferson University) Reporting in the Proceedings of the National Academy of Sciences, a team of Jefferson immunologists found that a specialized "human immune system" mouse model closely mimics a person's specific response and resolution of a tick-borne infection known as relapsing fever, caused by the bacteria Borrelia hermsii.

(National Academy of Sciences) The federal government is investing billions of dollars to encourage hospitals and health care providers to adopt health information technology so that all Americans can benefit.

(National Science Foundation) That seems to be the takeaway from new research that concludes "archaic" humans, somewhere in Africa during the last 20-60 thousand years, interbred with anatomically modern humans and transferred small amounts of genetic material to their offspring who are alive today.

University of Arizona geneticist Michael Hammer and a team of evolutionary biologists, geneticists and mathematicians report the finding in today's Proceedings of the National Academy of Sciences.

(Rice University) Rice University scientists have used X-ray crystallography to define the structure -- down to the atomic level -- of a common virus that causes juvenile diarrhea.

The new research is online this week in the Proceedings of the National Academy of Sciences and could help direct efforts to develop medications that block the virus before it becomes infectious.

(Penn State) In the war between drugs and drug-resistant diseases, is the current strategy for medicating patients may be giving many drug-resistant diseases a big competitive advantage, according to a research paper that will be published in the Proceedings of the National Academy of Sciences.

The paper argues for new research efforts to discover effective ways for managing the evolution and slowing the spread of drug-resistant disease organisms.

(Columbia University) Researchers at Columbia Engineering have established a new method to patch a damaged heart using a tissue-engineering platform that enables heart tissue to repair itself.

This breakthrough, recently published in the Proceedings of the National Academy of Sciences, is an important step forward in combating cardiovascular disease, one of the most serious health problems of our day.

(University of Pittsburgh) Pitt and Stanford researchers report in the Proceedings of the National Academy of Sciences that a supposedly inactive protein actually plays a crucial role in the ability of one the world's most prolific pathogens to cause disease and could also be important to other such pathogen-based diseases as malaria.

(National Academy of Sciences) Recent findings on the differences in heart disease among women and men and among blacks and whites show that characteristics such as gender and ethnicity matter when it comes to health research.

(Columbia University) Biologists look at cells in bulk, taking the average behavior as the norm and assuming that identical cells behave the same.

In the Proceedings of the National Academy of Sciences Sam Sia, assistant professor of biomedical engineering at Columbia Engineering, shows surprising variation in how cells behave during formation of a blood vessel.

Sia's team characterized, for the first time, what happens when endothelial cells move from an initial dispersed state to capillary-like structures.

(MedPage Today) -- Life expectancy in the U.S. lags behind that of many other high-income countries and is currently ranked by the United Nations at number 28, despite spending the most on healthcare, according to a National Academy of Sciences report.
