Nearly half of deaths for 12 cancers in California due to tobacco, higher than previously reported

A new UC Davis study reveals that close to half of the cancer deaths in California over two years (2017-2019) were associated with tobacco use, totaling 93,764 Californians. Tobacco control efforts have contributed to a decline in cancer mortality in California, but quitting is essential for patients with cancer.

Highest metal concentrations in US public water systems found among Hispanic/Latino and American Indian communities

A new study finds higher arsenic and uranium concentrations in public drinking water linked to communities with higher proportions of Hispanic/Latino and American Indian residents. The findings highlight inequalities in public water contaminant exposures affecting regions with more residents from communities of color.

Tracking plasma cell survival

A study by Osaka University tracked the survival of antibody-producing plasma cells, finding that most die shortly after immune response, but a small population can survive for months or years. The researchers identified molecular markers distinguishing these long-lived plasma cells from short-lived ones.

New study reveals how entrepreneurs avoid burnout and accumulate happiness

A large-scale study revealed that entrepreneurs are less at risk of burnout than salaried employees due to the positive psychological effects of entrepreneurial work. Entrepreneurs show less daily work recovery after regular working hours, indicating a 'positive workaholism'. This leads to a lower risk of burnout and increased happiness.

Pollination loss removes healthy foods from global diets, increases chronic diseases causing excess deaths

A new study finds that inadequate pollination leads to a 3-5% loss of fruit, vegetable, and nut production, resulting in 427,000 excess deaths annually from lost healthy food consumption. The health burden is greater in middle- and higher-income countries with high rates of non-communicable diseases.
