...study, which included 140 middle-aged volunteers with normal blood pressure, was designed to take a closer look at the link between noise and hypertension risk - a relationship that researchers still don't fully understand. "It seems plausible that if you have a lot of these transient [blood pressure] changes during the night - if you live around the airport for many years, for example - that in the end you might get some long-term effects on your blood pressure," says Jarup, "but we don't really know." Why the body responds to nighttime noise is also somewhat mysterious. While...

Plague lives in many rodent species, and is most often transferred to humans by the animals' fleas. Scientists know which regions of the world harbor infected animals, but they are only just beginning to understand the dynamics of plague infection. Its spread depends not just on Yersinia pestis but also on interactions among rodents and, crucially, on contact between humans and wildlife. Madagascar is a good example. For decades, plague was restricted to the highlands, according to a 2004 paper by researchers in Madagascar, Senegal and France. But it showed up on the coast in 1991, when the Asian shrew...
...demand for exclusive rights. We have designed a legal memorandum called an author’s addendum to reinforce them in negotiations with commercial publishers. The implementation of the proposal would require an effort at consciousness-raising, but that, too, is a good cause, because few faculty members understand how badly current conditions impede the communication of knowledge. The motion gives Harvard the possibility of setting an example that could spread. In place of a closed, privileged, and costly system, it will help open up the world of learning to everyone who wants to learn—and also...
