Expansion microscopy: a new technique to see inside microbes

Expansion microscopy: a new technique to see inside microbes

Biology

By Rosa García-Verdugo

How can scientists see the intricate details inside cells far too small for regular light microscopes? A powerful technique called expansion microscopy is revolutionizing how researchers study tiny organisms from plankton to developing embryos. Making the invisible visible Expansion microscopy works by doing the opposite to what we had been doing until now: instead of […]

Authors: Sarah Foster, Program Leader, Project Seahorse and Senior Researcher, Institute for the Oceans and Fisheries, University of British Columbia and Amanda Vincent, Professor, Institute for the Oceans and Fisheries, University of British Columbia Bottom trawlers extract one-quarter of the world’s fisheries catches by weight and raise significant ecological, economic and social concerns. Given that […]

Researchers at the University of Oregon have developed an artificial intelligence tool that can read genetic code the way large language models like ChatGPT read text. Scanning the genome for biological mutation patterns, the computer model traces pairs of genes back in time to their last common ancestor. It’s the first language model designed for […]

By Rosa García-Verdugo

Can a father’s lifestyle choices before conception influence the health of his future children? New research reveals that environmental factors affecting fathers can leave molecular footprints in embryos, shaping development and potentially impacting long-term health. Epigenetic inheritance For decades, scientists believed that inheritance was controlled exclusively by DNA sequences passed from parents to offspring. Today […]

Author: Gabriela Radulescu, Guggenheim Postdoctoral Fellow, Smithsonian Institution As humans began to explore outer space in the latter half of the 20th century, radio waves proved a powerful tool. Scientists could send out radio waves to communicate with satellites, rockets and other spacecraft, and use radio telescopes to take in radio waves emitted by objects […]

Authors: Roger S. Seymour, Professor Emeritus of Physiology, University of Adelaide and Edward Snelling, Faculty of Veterinary Science, University of Pretoria If you’ve ever wondered why the giraffe has such a long neck, the answer seems clear: it lets them reach succulent leaves atop tall acacia trees in Africa. Only giraffes have direct access to […]

Author: Rohini Subrahmanyam is a PhD biologist turned science journalist. Insects that tuck away wings; a protist with an accordion-like neck — studying these clever creases may inspire foldable structures for drones As the microscopic, tear-shaped Lacrymaria olor swims around hunting for food, it does something remarkable: In a blink, the tiny protist extends its […]

Rare bumble bee’s downfall began long before effects from humans

BiologyEvolutionGenetics

By Mapping Ignorance

A rare North American bumble bee may have been on a path toward extinction long before modern human impacts, suggesting that its long-term genetic vulnerability made it especially fragile and less able to cope with both past and current environmental stresses. The study focused on the Franklin bumble bee, once found only in parts of […]
