Since the beginning of Earth's history, tiny particles of rock and metal from space have been hitting our planet. On clear nights, we can even see their traces as shooting stars. Trapped in layers of rock, these micrometeorites can remain preserved for billions of years. An international research team led by the University of Göttingen and including the Open University, the University of Pisa, and Leibniz University Hannover has developed a method that allows them to reconstruct the atmosphere of the past using fossilized micrometeorites. The results were published in Communications Earth & Environment.

A new institute, based at Brown and supported by a $20 million National Science Foundation grant, will convene researchers to guide development of a new generation of AI assistants for use in mental and behavioral health.

Researchers at Chan Zuckerberg Biohub San Francisco and Stanford University have developed an AI-driven Virtual Lab through which a team of AI agents, each equipped with varied scientific expertise, can tackle sophisticated and open-ended scientific problems by formulating, refining, and carrying out a complex research strategy — these agents can even conduct virtual experiments, producing results that can be validated in real-life laboratories.

New research published in npj Robotics addresses the challenge of flying small quadrotors in air ducts as small as 35 cm (14 inches). This research, led by a team of researchers from Inria, CNRS, Université de Lorraine, and Aix-Marseille Université, opens a new way of accessing and inspecting highly-confined environments.

Many soil microbes play a vital role in ecosystems, as they help plants access nutrients and water and assist in stress tolerance such as during drought and to defend against pathogens. One such group of soil microbes are arbuscular mycorrhizal, aka AM, fungi, which are associated with the roots of approximately 70% of plant species on land.  new Dartmouth-led study reports on how global climate conditions affect AM fungal spore traits and the species biogeographic patterns. The results are published in the Proceedings of the National Academy of Sciences.
