Authors: Elisa Rigosi, Researcher in Sensory Biology, Department of Biology, Lund University and David O’Carroll, Professor of Sensory Biology, Department of Biology, Lund University One bee has long been regarded as a benchmark for visual performance: the honeybee drone. These male honeybees (Apis mellifera) have evolved highly specialised eyes for detecting queens during mating flights […]

Human activity has not always harmed biodiversity – quite the opposite

For millennia, farming in Switzerland did not reduce plant diversity but helped increase it, researchers have shown in a detailed reconstruction covering the past 7000 years. Only recent decades paint a different picture. The fall of the Roman Empire and major plague outbreaks: These events not only affected people but also reduced plant diversity on […]

Authors: Thomas M. Pitot, Chercheur postdoctoral en microbiologie, Université du Québec à Chicoutimi (UQAC) and Catherine Girard, Professeure-Chercheure en microbiologie, Université Laval Viruses play a major role in the functioning of ecosystems. They profoundly influence the dynamics of microbial communities, flow of matter and global biogeochemical cycles. Yet despite their abundance and ecological importance, many […]

Cosmic bombardment may have opened Earth’s crust for prebiotic chemistry

By Mapping Ignorance

Asteroids and planetesimals regularly bombarded Earth between about 4.6 billion and 3.5 billion years ago, during the Hadean and Archean eons. Because few rocks today are more than 4 billion years old, our understanding of the planet’s environment during that time is limited. However, samples from the moon and its cratered surface hint at the […]

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 […]
