Planetary Boundaries guide humanity’s future on Earth
Abstract Human pressures have pushed the Earth system deep into the Anthropocene, threatening its stability, resilience and functioning. The Planetary Boundaries (PB) framework emerged against these threats, setting safe levels to the biophysical systems and processes that, with high likelihood, ensure life-supporting Holocene-like conditions. In this Review, we synthesize PB advancements, detailing its emergence and…

Physicists Stir a Supersolid For First Time, Proving Its Bizarre Dual Nature
Scientists on Wednesday said that they have successfully stirred a strange matter called a “supersolid” – which is both rigid and fluid – for the first time, providing direct proof of the dual nature of this quantum oddity. In everyday life, there are four states of matter – solid, liquid, gas, and the rarer plasma.…

A probable ancient nearshore zone in southern Utopia on Mars unveiled from observations at the Zhurong landing area
Abstract The Chinese Mars rover Zhurong successfully landed in southern Utopia Planitia on Mars in May 2021. Previous research suggested a Hesperian ocean may have existed in the northern lowland on Mars. Recent research observed water-related features at the Zhurong landing site from in situ data. In this study, we conducted a comprehensive geomorphological analysis…

The antibodies don’t work! The race to rid labs of molecules that ruin experiments
Carl Laflamme knew what protein he wanted to study, but not where to find it. It is encoded by a gene called C9ORF72, which is mutated in some people with the devastating neurological condition motor neuron disease, also known as amyotrophic lateral sclerosis. And Laflamme wanted to understand its role in the disease. When he…
