California and 14 other states sued the US Environmental Protection Agency on Thursday over its decision to suspend an Obama-era rule aimed at limiting pollution from trucks.

Although natural terrestrial ecosystems have sequestered ~25% of anthropogenic CO2 emissions, the long-term sustainability of this key ecosystem service is under question. Forests have traditionally been viewed as robust carbon (C) sinks; however, extreme heat-waves, drought and wildfire have increased tree mortality, particularly in widespread semi-arid regions, which account for ~41% of Earth's land surface.

INSPIRED by tiny structures on transparent butterfly wings, scientists have developed a light-manipulating surface for more effective and longer-lasting eye implants for glaucoma patients.

California, Brazil and South Africa have all recently experienced major drought, threatening serious disruption to supplies for major cities ('Day Zero' events).

Prenatal exposure to organophosphate (OP) pesticides has been linked with poorer neurodevelopment and behaviors related to autism spectrum disorders (ASD) in previous studies, including in the Center for Health Assessment of Mothers and Children of Salinas (CHAMACOS) study, a birth cohort living in the agricultural Salinas Valley in California. The objective of the study is to investigate the association of prenatal exposure to OP pesticides with traits related to ASD, in childhood and adolescents in CHAMACOS.

This study investigated potential changes in future precipitation, temperature, and drought across 10 hydrologic regions in California. The latest climate model projections on these variables through 2099 representing the current state of the climate science were applied for this purpose. Changes were explored in terms of differences from a historical baseline as well as the changing trend.
