Sun and moon trigger deep tremors on San Andreas Fault
When the sun and moon are aligned with the San Andreas Fault they tug on it enough to increase the tremor rate deep underground. While these faint tremors have not been linked to earthquakes, the tremors are associated with increased stress on the fault and may up the risk for future quakes.
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.
