Researchers examined plans for managing groundwater in the Central Valley. They found local plans leave thousands of wells at risk of running dry.
Even though California enacted sweeping legislation nearly a decade ago to curb excessive agricultural pumping of groundwater, new research predicts that thousands of drinking water wells could run dry in the Central Valley by the time the law’s restrictions take full effect in 2040.
The researchers warned that unless local agencies adopt more stringent measures or come up with backup plans, many people in the Central Valley could be left without access to drinking water, and low-income communities could be severely affected.
They found that more than 5,000 domestic wells would be left completely dry, while an additional 4,000 household wells would be “partially dewatered,” leading to problems such as low water pressure or damaged pumps. “The numbers are quite large and have the potential to impact many, many people,” said Darcy Bostic, a researcher with the West Sacramento-based. nonprofit Rural Community Assistance Corp., who led the study.

In major breakthrough, researchers close in on potential preeclampsia cureResearchers have achieved a significant breakthrough in identifying the primary cause and potential treatment for preeclampsia, a severe pregnancy complication. Experts pinpointed a toxic protein named cis P-tau in the blood and placenta of individuals with preeclampsia. The study describes cis P-tau as a pivotal circulating instigator of preeclampsia. An antibody developed in 2012 to target only the toxic protein while leaving its healthy counterpart unscathed is currently undergoing clinical trials in human patients suffering from traumatic brain injury and Alzheimer's Disease. The antibody has shown promising results in animal models and human cell cultures in treating the brain conditions. Upon testing this antibody in mice, the researchers found the all symptoms associated with preeclampsia were corrected.
