New research reveals credit rating agencies responded too slowly to COVID-19

The first study into the effect of COVID-19 on sovereign credit ratings found that rating agencies were slow to react to the pandemic's unprecedented economic and fiscal reverberations. The research raises questions about the timeliness and reliability of prominent creditworthiness measures, with potentially significant consequences for investors and for public debt and global financial stability.

Can sustainability standards effectively mitigate food system challenges?

While agrifood production is essential for feeding our growing global population, it can also contribute to environmental and social problems, including deforestation, biodiversity loss, poor or precarious labor conditions, and persistent poverty. Certification and standards can encourage use of sustainable production practices, but how effective are such programs in addressing food system challenges? A new study from a team of international researchers reviews the literature on sustainability standards and identifies a series of important questions.

Earth and Venus grew up as rambunctious planets

What doesn't stick comes around: Using machine learning and simulations of giant impacts, researchers at the Lunar and Planetary Laboratory found that the planets residing in the inner solar systems were likely born from repeated hit-and-run collisions, challenging conventional models of planet formation.

Kirigami cools electronics

Scientists from SANKEN (The Institute of Scientific and Industrial Research) at Osaka University, Oita National College of Technology, and Tokyo Polytechnic University demonstrated enhanced passive convective cooling using cellulose nanofiber films designed based on kirigami, a traditional paper design form similar to origami. The difference when compared with origami is that, in addition to folding, kirigami involves cutting the paper as well. This work may enable small flexible electronic devices to operate without overheating.
