Agricultural technology for net negative greenhouse gas emissions

Agricultural technology for net negative greenhouse gas emissions

Ecology

By César Tomé

As the Earth’s human population grows, greenhouse gas emissions from the world’s food system are on track to expand. A new study demonstrates that state-of-the-art agricultural technology and management can not only reduce that growth but eliminate it altogether by generating net negative emissions – reducing more greenhouse gas than food systems add. Employing additional […]

By Rosa García-Verdugo

Recent research has demonstrated that obesity impairs the mechanisms that allow our brains to realize when our stomachs are full and that these changes are maintained despite dieting, giving insights into why it is difficult for obese people to avoid excessive eating and why there is often a yo-yo effect after dieting. It has been […]

Materials

By DIPC

Spurred by outstanding optical properties, chemical stability, and facile bioconjugation, plasmonic metals have become the first-choice materials for optical signal transducers in biosensing. While the design rules for surface-based plasmonic sensors are well-established and commercialized, there is limited knowledge of the design of sensors based on nanoparticle aggregation. The working principle of biosensors built around […]

By César Tomé

amorphous Scientists have dedicated their efforts to studying topological materials, focusing on the shape, or topology, of their electronic structures. These materials exhibit unique properties that have the potential to be harnessed for next-generation devices, despite their invisible nature in real space. Initially, it was believed that only crystalline materials, characterized by highly ordered atoms […]

Computer scienceMaterials

By César Tomé

A novel computer memory design has been created by researchers, offering significant enhancements in performance while simultaneously addressing the pressing need to minimize energy consumption in internet and communications technologies. Projections suggest that these technologies could account for nearly one-third of the world’s electricity consumption within the next decade. A team of researchers has devised […]
