Sitting directly over a complex network of fault lines, Haiti is one of the most earthquake-prone nations on Earth. In 2021, the Nippes earthquake became the latest to devastate the country, and today, researchers are still piecing together the timeline of seismic events which unfolded during the earthquake. Through their research, Professor Jeremy Maurer and colleagues at Missouri University of Science and Technology have described how the Nippes earthquake originated, shifted, and ruptured a major fault line, triggering numerous ‘afterslip’ events in the following days.

Pollinators, including honey bees, wild bees, butterflies and many other insects, are some of the most important creatures on our planet. By pollinating plants, both wild and cultivated, they have an essential role in maintaining wider ecosystems and ensuring our food security. However, we have come to take them for granted, and don’t fully appreciate their function in ensuring our ongoing survival. Insects are declining at a truly alarming rate. Among other factors human activities such as industrial farming and corresponding insecticide and fungicide use over large areas of land to protect food crops against pests and disease are considered to be major contributors. Many different pesticides have also been detected in honeybee colonies. Scientists are attempting to uncover the specific factors involved in insect decline, before it’s too late. Recent research by Sarah Manzer and colleagues in the research groups of Prof. Ricarda Scheiner and Prof. Ingolf Steffan-Dewenter at the Julius Maximilians Universität Würzburg in Germany has shed new light on a potential culprit: a combination of insecticides and fungicides commonly used in agriculture.

The Sichuan basin in southern China is a region of deep geological and seismological complexity, which has so far prevented researchers from understanding its tectonic past. Through fresh analysis of previous observations, combined with the latest modelling techniques, a team led by Dr. Zhe Su at the National Institute of Natural Hazards, Beijing, suggests for the first time that the entire Sichuan basin is slowly rotating. Their result could explain the origins of one of the deadliest earthquakes in living memory, and could also help seismologists to better predict when earthquakes will strike the region in the future.

Research by Dr. Claudia Ituarte-Lima and Dr. Radu Mares at Lund University examines how a pioneering environmental agreement in Latin America and the Caribbean introduces new ways of protecting nature and human rights. Their study reveals both opportunities and challenges in how this regional treaty interacts with European Union trade laws, offering insights into how different regions can work together to protect the environment and strengthen democracy.

The oceans, huge and brimming with diverse lifeforms, pose no less a struggle for survival for their inhabitants than that faced by creatures on dry land. Evolution has furnished marine organisms with huge array of defensive, and indeed, offensive adaptations to help them to thrive in this battleground. Among the organisms who live and compete in the ocean are dinoflagellates. These are small, single-celled creatures that are an important component of plankton found in marine ecosystems. Despite their tiny size, dinoflagellates such as Karlodinium veneficum can wield potent biochemical weaponry that gives them an edge against other competing organisms. Decades since the discovery of the toxic properties of Karlodinium veneficum, researchers such as Dr. Allen Place of the University of Maryland Center for Environmental Sciences, and his colleagues, have begun to unravel the secrets of its potent toxins, called karlotoxins. Their findings offer fascinating insights into the interactions of marine life and the weapons they adopt to capture prey and deter predators.

It’s not difficult to picture a lush forest landscape populated with majestic deer and elk, long admired for their prowess and strength. Now, imagine that same scene, but instead of healthy and happy animals browsing a forest ecosystem, we see creatures that are thin and disoriented, that struggle to run or even stand, with halting and confused movements that are pitiable and distressing to watch. This is the harsh reality of Chronic Wasting Disease, an illness that currently has no cure and that threatens such wildlife around the world. Part of the challenge with Chronic Wasting Disease is the difficulty in studying it reliably in wildlife. The disease has subtle signs at an early stage, and it is difficult to obtain robust and reproducible data from large, wild animals who often live in remote and poorly accessible forest ecosystems. Consequently, researchers have turned to an unlikely but powerful ally, the tiny laboratory mouse, to model and study the disease under laboratory conditions. Dr. Andrea Grindeland of the McLaughlin Research Institute, and her colleagues, have authored a review of the existing mouse models of Chronic Wasting Disease. These tiny creatures have been engineered to mimic the biology of cervids, such as deer and elk, and are providing crucial insights into how Chronic Wasting Disease evolves, is transmitted, and how it might one day be controlled or even eradicated.
