Author: Gerlinde Bigga, Scientific Coordinator of the Leibniz Science Campus “Geogenomic Archaeology Campus Tübingen”, University of Tübingen The last two decades have seen a revolution in scientists’ ability to reconstruct the past. This has been made possible through technological advances in the way DNA is extracted from ancient bones and analysed. These advances have revealed […]

Author: Knut von Salzen, Senior Research Scientist, Marine Cloud Brightening Research Program, University of Washington Winter is setting in across the Northern Hemisphere, and with it, cold and cloudy winter days. Clouds play a vital role in the environment, providing rain but also reflecting sunlight before it reaches the Earth’s surface. But between 2003 and […]

BiochemistryBiotechnologyChemistryMaterials

By Invited Researcher

Order on a molecular scale is difficult to control. The systems with highest possible order are crystals, formed by long arrays of repeating constituent components in all directions. The most familiar examples of crystals encountered in daily life are table salt and sucrose, the sugar in our kitchens. Every grain of table salt is a […]

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 […]

Author: Anthony Booker, Reader in Ethnopharmacology, University of Westminster “Double double toil and trouble” is a quote from Shakespeare’s Macbeth that conjures images of evil witches making potions in giant cauldrons. But the truth was that women persecuted as witches were probably legitimate healers of the time. Prior to the 14th century, female healers were […]

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: Paul C. Sereno, Professor of Paleontology, University of Chicago Dinosaur “mummies” couldn’t have been further from my mind as I trudged up a grassy knoll on the Zerbst Ranch in east-central Wyoming, followed by University of Chicago undergraduates on a field trip linked to my “Dinosaur Science” course. As a university professor, I realized […]

Cosmology

By Invited Researcher

Author: Florian Neukart, Assistant professor of Physics, Leiden University For more than a century, physics has been built on two great theories. Einstein’s general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles and fields. Both work brilliantly in their own domains. But put them together and […]

Biomedicine

By Invited Researcher

Acute myeloid leukemia (AML) with t(6;9)/DEK::NUP214 is recognized as a separate entity in the World Health Organization classification of myeloid neoplasms, accounting for 1% of all AML cases and characterized by a high relapse rate and young age at diagnosis . The t(6;9) chromosomal rearrangement results in the fusion of almost the entire peptide sequence […]
