UT Southwestern researchers find calcium intake contributing factor in formation of kidney stones

Researchers found that urinary calcium levels play a significant role in the formation of both calcium oxalate and calcium phosphate stones. The studies suggest that patients with elevated intestinal calcium absorption and urinary calcium levels may need to limit their calcium intake to prevent kidney stone formation.

Geologist comments on Oregon's tsunami hazard

Scientists studying uplift along the Oregon coast reveal similarities with past earthquakes, indicating an accumulation of strain for a potential future earthquake. A tsunami could cause widespread damage from Northern California to Vancouver, B.C., with waves arriving within minutes after shaking ends.

Bound for destruction

Researchers at RIKEN Center for Developmental Biology identified Nedd4 as a key player in protecting the Notch receptor from activation. The study found that Nedd4 works as an antagonist of Notch signaling, suppressing its activity and preventing molecular loose cannons from fouling the precisely ordered workplan.
