Are the grandkids worth it? Climate change policy depends on how we value human population

A new study finds that reducing greenhouse gas emissions to protect future generations from environmental destruction could save tens of billions of dollars annually, especially in wealthier countries. By valuing human population differently, policymakers can make more informed decisions about climate policy.

The advent of 'green' cattle

A new method of carbon footprinting for pasture-based cattle production systems can identify 'green' cattle within a herd, reducing greenhouse gas emissions. The study found that existing methods underestimates the impacts of poorly performing animals, which produce disproportionately large amounts of methane.

Microscopic defects make batteries better

Researchers found that microscopic defects in electrodes enable lithium to hop inside the cathode along multiple directions, increasing reactive surface area and allowing for more efficient exchange of lithium ions. This discovery challenges traditional thinking on how electrode shape should be optimized for battery performance.
