First large-scale census of coral heat tolerance published In a first-of-its-kind study, Florida's  critically endangered staghorn corals were surveyed to discover which ones can better withstand future heatwaves in the ocean. Insights from the study, led by scientists at Shedd Aquarium and the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science, help organizations working to restore climate-resilient reefs in Florida and provide a blueprint for the success of restoration projects globally.

How Bali could teach the world to manage its limited resources Water is a limited resource. As such, efficient ways to jointly manage and optimize water reserves are essential for our present and future. But how can a well-balanced system be established? In order to single out the relevant parameters, an international team of scientists, including Stefan Thurner from the Complexity Science Hub Vienna (CSH), applied a method from physics to a system in equilibrium: the century-old rice irrigation practices in Bali.

New tool offers ways to improve CRISPR gene-editing method The ability to edit the genome by altering the DNA sequence inside a living cell is powerful for research and holds enormous promise for the treatment of diseases. However, existing genome editing technologies frequently result in unwanted mutations or can fail to introduce any changes at all. These problems have kept the field from reaching its full potential.

Europeans in the Americas 1,000 years ago Columbus was not the first European to reach the Americas. The Vikings got there centuries before, although exactly when has remained unclear. Here, an international team of scientists show that Europeans were already active in the Americas in 1021 AD.

Unmasking the magic of superconductivity in twisted graphene The discovery in 2018 of superconductivity in two single-atom-thick layers of graphene stacked at a precise angle of 1.1 degrees (called 'magic'-angle twisted bilayer graphene) came as a big surprise to the scientific community. Since the discovery, physicists have asked whether magic graphene's superconductivity can be understood using existing theory, or whether fundamentally new approaches are required—such as those being marshalled to understand the mysterious ceramic compound that superconducts at high temperatures. Now, as reported in the journal Nature, Princeton researchers have settled this debate by showing an uncanny resemblance between the superconductivity of magic graphene and that of high temperature superconductors. Magic graphene may hold the key to unlocking new mechanisms of superconductivity, including high temperature superconductivity.

Origin of domestic horses finally established Horses were first domesticated in the Pontic-Caspian steppes, northern Caucasus, before conquering the rest of Eurasia within a few centuries. These are the results of a study led by paleogeneticist Ludovic Orlando, CNRS, who headed an international team including l'Université Toulouse III—Paul Sabatier, the CEA and l'Université d'Évry. Answering a decades-old enigma, the study is published in Nature on 20 October 2021.
