Researchers uncover «diary entries» in fossil fish ear stones using electron microscopy Fossilized fish ear stones – known as otoliths – can reveal far more than previously thought. In a recent study, a team of palaeontologists from the University of Vienna demonstrated that a refined electron microscopy technique can makeContinuar Leyendo
New York, October 15, 2025.- Ant societies are built on scent. Pheromones guide the insects to food, warn them of predators, and regulate the rhythms of their colonies. This chemical communication system is governed by a simple rule: one receptor, one neuron. Ant genomes contain hundreds of odorant receptor genes,Continuar Leyendo
Thanks to the support of the Werner and Hedy Berger-Janser Foundation for Cancer Research, the University of Bern and Inselspital, Bern University Hospital, have been able to establish an endowed professorship for Clinical Cancer Informatics. The professorship is endowed with 2.1 million Swiss francs and aims to optimize the useContinuar Leyendo
On Mars, dust devils and winds reach speeds of up to 160 km/h and are therefore faster than previously assumed: This shows a study by an international research team led by the University of Bern. The researchers analyzed images taken by the Bernese Mars camera CaSSIS and the stereo cameraContinuar Leyendo
The NASA/ESA/CSA James Webb Space Telescope has provided the first direct measurements of the chemical and physical properties of a potential moon-forming disc encircling a large exoplanet. The carbon-rich disc surrounding the world called CT Cha B, which is located 625 light years away from Earth, is a possible constructionContinuar Leyendo
Could a simple blood test reveal how well someone is aging? A team of researchers led by Wolfram Weckwerth from the University of Vienna, Austria, and Nankai University, China, has combined advanced metabolomics with cutting-edge machine learning and a novel network modeling tool to uncover the key molecular processes underlyingContinuar Leyendo
An international research team led by the Department of Botany and Biodiversity Research at the University of Vienna has made an extraordinary discovery: fossilised lime blossoms and fossilised bumble bees were found in 24-million-year-old sediments at the Enspel Fossil-Lagerstätte (Rhineland-Palatinate, Germany) – along with evidence of their interaction in theContinuar Leyendo
In our nearby stellar neighbourhood, a burned-out star is snacking on a fragment of a Pluto-like object. With its unique ultraviolet capability, only the NASA/ESA Hubble Space Telescope could identify that this meal is taking place. Paris, Sept 19, 2025.-The stellar remnant is a white dwarf about half the massContinuar Leyendo
Washington, Sept 11, 2025.- Una muestra recolectada por el rover Perseverance, el vehículo explorador de la NASA en Marte, en el antiguo lecho de un río seco en el cráter Jezero podría conservar evidencia de vida microbiana antigua. Tomada el año pasado de una roca llamada Cheyava Falls, la muestra,Continuar Leyendo
Lipid metabolism and cell membrane function can be disrupted in the neurons of people who carry rare variants of ABCA7. Cambrigde, Sept 10, 2025.- A new study from MIT neuroscientists reveals how rare variants of a gene called ABCA7 may contribute to the development of Alzheimer’s in some of theContinuar Leyendo
