Mapping ‘fossil water’ helps achieve sustainable groundwater management in California

Oct. 22, 2020- 
Identifying the areas where paleowater or “fossil water” — water that recharged before the Holocene started 12,000 years ago — is pumped for drinking water supply helps managers decide whether groundwater can sustainably meet future demands. This type of groundwater recharged during rainy periods under cooler and wetter conditions that ended about 10,000 years ago. Since the hydrologic...

Lab team develops first-ever living 3D-printed aneurysm to improve surgical procedures, personalize treatments

Oct. 21, 2020- 
Brain aneurysms affect about one in every 50 Americans and can lead to serious medical emergencies, including stroke, brain damage and death if they burst. Existing treatment options are limited and often invasive, and surgical outcomes can vary widely from person to person. But medical practitioners may be able to improve existing treatment methods and develop new personalized ones...
