Researchers have uncovered a remarkable fossil site in a remote part of Canada’s Northwest Territories, offering unprecedented insight into the earliest evolution of complex animal life on Earth. Findings from the site represent life from the Ediacaran biota—soft-bodied organisms that lived on the seafloor more than 500 million years ago—and push back the origins of animal movement and sexual reproduction by 5-10 million years.

A new study from the University of Copenhagen shows that marine heatwaves can disrupt microscopic moving structures on the surface of reef-building corals that support their oxygen uptake. When seawater temperature crosses a critical threshold, this oxygen supply mechanism collapses, increasing the risk of coral death.

The earliest known eukaryotes, the ancestors of all complex life on Earth, lived in oxygenated, shallow marine environments nearly 1.7 billion years ago, according to a new study led by researchers at McGill University and the University of California, Santa Barbara. The findings cast doubt on the long-held belief that early complex life emerged in oxygen-poor environments or floated freely in the open ocean.

The School of Medicine’s University of Maryland - Medicine Institute for Neuroscience Discovery (UM-MIND) has received $2.9 million in federal funding to build a leading-edge advanced microscopy facility designed to accelerate neuroscience discoveries and innovations.The funding will be used, in part, to purchase a new, $2 million state-of-the-art fluorescence microscope — called MINFLUX — only a handful of which are currently available in the U.S.

Osteosarcoma is an aggressive bone cancer characterized by high rate of recurrence and metastasis. In a new study, researchers show that restoring the RNA-editing enzyme adenosine deaminase acting on RNA 2 (ADAR2) slows tumor growth, reduces invasion, promotes bone-like differentiation, and improves chemotherapy sensitivity in cell and mouse models. The findings identify IGFBP7 RNA editing as a key mechanism underlying these effects, highlighting a potential differentiation-based treatment strategy for pediatric patients with bone cancer.
