Scientific Journal Offers Flat Fee to Authors for “All You Can Publish”
Science-publishing ventures continually battle for market space, yet most operate on one of only two basic business models. Either subscribers pay for access, or authors pay for each publication—often thousands of dollars—with access being free. But in what publishing experts say is a radical experiment, an open-access venture called PeerJ, which formally announced its launch on 12 June, is carving out a fresh niche. It is asking its authors for only a one-off fee to secure a lifetime membership that will allow them to publish free, peer-reviewed research papers.
Amazon Tribe Gives Clues to Heart-Healthy Lifestyles
Investigating indigenous Amazonian or African peoples who still follow a hunter-gatherer or forager-horticulturist lifestyle is giving new insights into how diet and lifestyle affect the heart as humans age.
Two new studies found that these types of hunter-gatherer or foraging peoples have lower increases in blood pressure related to their age and are less likely to have hardening of the arteries than people with more modern lifestyles.
Lifestyle factors such as high levels of physical activity and large amounts of fruits and vegetables — and low calories — in their diets may help protect these groups against those health problems, the researchers said.
Radiation Exposure from Medical Imaging Has Increased Even at HMOs
Concern about overexposure to radiation due to excessive use of medical imaging has come to the fore in recent years. Now, a study led by researchers at the University of California, San Francisco (UCSF) and Group Health Research Institute, shows that medical imaging is increasing even in health maintenance organization systems (HMOs), which don't have a financial incentive to conduct them.
