Pregnant people might not be getting the nutrients they need, according to new research from Stevens

According to a recent study published in The Journal of Nutrition, over 90% of pregnant individuals are potentially failing to get enough iron, vitamin D, or vitamin E from the food they eat. Almost two-thirds were found to be getting insufficient dietary folate, a critical nutrient that helps prevent birth defects.

Groundwater pumping drives rapid sinking in California

A new study reveals that the San Joaquin Valley in California has been sinking at an average rate of nearly an inch per year between 2006 and 2022. The researchers estimate that the land sank by over 12 inches during the four-year gap in satellite data, highlighting the urgent need for mitigation strategies.

Columbia Aging Center epidemiologist co-authors new report from National Academies on using race and ethnicity in biomedical research

The National Academies report outlines nine actionable recommendations to advance the responsible use of race and ethnicity in biomedical research, including community engagement and data inclusivity. The report aims to provide a key guide for researchers considering using race and ethnicity throughout their research process.

Most Medicare beneficiaries do not compare prescription drug plans – and may be sticking with bad plans

A USC Schaeffer study found that over half of Medicare beneficiaries with stand-alone Part D plans did not switch due to lack of plan comparisons, with many unaware of how to change plans or missing out on better coverage options. This complacency allows insurers to exploit beneficiaries' inattention and boost profits.
