Scientists have identified a natural compound, (Z)-3-hexenyl butyrate (HB), that can induce stomatal closure in plants, a defense mechanism to conserve water and protect against pathogens. This discovery could lead to more sustainable agricultural practices by enhancing crop resilience to environmental stresses without the need for synthetic pesticides.

A recent study published in Nature Geoscience provides groundbreaking insights into long-term changes in tropical weather patterns that are leading to an increased frequency of extreme weather events such as heatwaves and heavy rainfall in the Indo-Pacific. These changes are possibly driven by global warming, among other factors. The paper, titled “Indo-Pacific regional extremes aggravated by changes in tropical weather patterns”, employs a recently proposed methodology that characterises occurrence trends of weather patterns using atmospheric analogues, which are linked to the concept of recurrences in dynamical systems theory.

The Kavli Foundation and the U.S. National Science Foundation are collaborating to accelerate research in the emerging field of neurobiology in changing ecosystems. Awardees of the first Kavli-NSF grants will study the impact of atmospheric pollutants on the sense of smell in pollinators, and how neural circuits adapt to changes in temperature.

Research shows a clear shift in transportation choices under extreme heat conditions. Car use increases, while trips made by walking, biking and public transit drop significantly. On average, public transit trips fall by nearly 50% on extreme heat days as individuals seek relief in air-conditioned private vehicles.
