New human reproductive hormone could lead to novel contraceptives
Given the ubiquity of fertility clinics and the popularity of in vitro fertilization, one would think that doctors fully understand the reproductive system. It's surprising, then, that a new reproductive hormone has been discovered in humans, one that supresses fertility. The discovery by UC Berkeley neuroscientists could lead to new contraceptives and treatments for cancer and disorders such as precocious puberty.
Disability may be on the rise again after 20-year decline
The 20-year decline of disability rates among Americans may have ended, according to a new study led by researchers at UC Berkeley and the University of Toronto. The researchers found that disability rates among non-institutionalized older Americans increased 9 percent between 2000 and 2005. The passage of meaningful health care reform could help stem the increase in disability rates, the authors said.
