Cancers are the second leading cause of death in the world, after cardiovascular diseases. Their seriousness lies in their diversity – some can be effectively treated with surgery, chemotherapy and radiotherapy, while others respond poorly or not at all. Improving the treatment of these diseases is therefore a major challenge. For several years, the development […]

Mesodinium Author: Ramón Muñoz-Chápuli has been Professor of Animal Biology in the University of Málaga until his retirement. He has investigated for forty years in the fields of developmental biology and animal evolution. The ciliate Mesodinium rubrum acquires phototrophy by ingestion of a photosynthetic cryptomonad. Besides the stolen plastid (derived from a secondary endosymbiotic event […]

Pyrite, also known as “fool’s gold,” is an abundant iron sulphide mineral in the Earth’s crust. All organisms need iron and sulphur to grow. Because pyrite does not dissolve in oxygen-free conditions, scientists previously thought that organisms could not use pyrite in the absence of oxygen. Research shows that certain single-celled microorganisms can dissolve pyrite […]

Imagine an old-growth forest in the fading light of a summer evening. As the last of the sun’s rays disappear beneath the horizon, a tiny flash catches your eye. You turn around, hold your breath; it blinks again, hovering 2 feet above the leaf litter. Across the dusky glade, a fleeting response. Then another one […]

Are we alone in the universe? This is a question that has intrigued humans for centuries and inspired countless studies and works of fiction. But are we getting closer to finding this out? Now that the James Webb Space Telescope (JWST) is in operation, we might have taken one giant leap in being able to […]
