Climate change could become the main driver of biodiversity decline by mid-century
Global biodiversity has declined between 2% and 11% during the 20th century due to land-use change alone, according to a large multi-model study. Projections show climate change could become the main driver of biodiversity decline by the mid-21st century. 04/25/2024 04:15 PM
Food in sight? The liver is ready!
What happens in the body when we are hungry and see and smell food? A team of researchers has now been able to show in mice that adaptations in the liver mitochondria take place after only a few minutes. Stimulated by the activation of a group of nerve cells in the brain, the mitochondria of the liver cells change and prepare the liver for the adaptation of the sugar metabolism. The findings could open up new avenues for the treatment of type 2 diabetes. 04/25/2024 04:15 PM
Voluntary corporate emissions targets not enough to create real climate action
Companies' emissions reduction targets should not be the sole measure of corporate climate ambition, according to a new perspective paper. 04/25/2024 04:14 PM

Treatment for deadly superbug C. diff may be weakening
The antibiotic vancomycin, recommended as first-line treatment for infection caused by the deadly superbug C. difficile (C. diff), may not be living up to its promise, according to new research. 04/25/2024 01:16 PM
With hybrid brains, these mice smell like a rat
Mice lacking an olfactory system have had their sense of smell restored with neurons from rats, the first time scientists have successfully integrated the sensory apparatus of one species into another. 04/25/2024 01:15 PM
Synthetic droplets cause a stir in the primordial soup
Our bodies are made up of trillions of different cells, each fulfilling their own unique function to keep us alive. How do cells move around inside these extremely complicated systems? How do they know where to go? And how did they get so complicated to begin with? Simple yet profound questions like these are at the heart of curiosity-driven basic research, which focuses on the fundamental principles of natural phenomena. 04/25/2024 01:14 PM

IRIS beamline at BESSY II extended with nanomicroscopy
The IRIS infrared beamline at the BESSY II storage ring now offers a fourth option for characterizing materials, cells and even molecules on different length scales. The team has extended the IRIS beamline with an end station for nanospectroscopy and nanoimaging that enables spatial resolutions down to below 30 nanometers. The instrument is also available to external user groups. 04/25/2024 01:14 PM
Towards novel promising perovskite-type ferroelectric materials: High-pressure synthesis of rubidium niobate
Researchers have pioneered a breakthrough in ferroelectric material development. They've engineered a novel displacement-type ferroelectric material boasting remarkable dielectric properties. Their achievement includes the successful synthesis of rubidium niobate (RbNbO3), a compound previously deemed challenging to produce under pressures exceeding 40,000 atmospheres. Additionally, they characterized how polarization changes across a wide temperature range during phase transitions. This breakthrough can lead to new design guidelines for ferroelectric materials. 04/25/2024 01:14 PM
AI in medicine: The causality frontier
Machines can learn not only to make predictions, but also to handle causal relationships. An international research team shows how this could make therapies safer, more efficient, and more individualized. 04/25/2024 01:14 PM
How electric vehicle drivers can escape range anxiety
Two of the biggest challenges faced by new and potential electric vehicle (EV) drivers are range anxiety and speed of charging, but these shouldn't have to be challenges at all. Researchers discovered that a change in refueling mindset, rather than improving the size or performance of the battery, could be the answer to these concerns. 04/25/2024 01:14 PM
Advanced cell atlas opens new doors in biomedical research
Researchers have developed a web-based platform that offers an unprecedented view of the human body at the cellular level. The aim is to create an invaluable resource for researchers worldwide to increase knowledge about human health and disease. 04/25/2024 01:13 PM
Using AI to improve diagnosis of rare genetic disorders
Diagnosing rare Mendelian disorders is a labor-intensive task, even for experienced geneticists. Investigators are trying to make the process more efficient using artificial intelligence. The team developed a machine learning system called AI-MARRVEL (AIM) to help prioritize potentially causative variants for Mendelian disorders. 04/25/2024 01:13 PM
The secret to saving old books could be gluten-free glues
'Bookworm' is a cute thing to call a voracious reader, but actual bookworms -- as well as microorganisms and time -- break down the flour pastes commonly used to keep old publications in one piece. Now, researchers have analyzed the proteins in wheat-based glues applied in historic bookbinding to provide insights on their adhesiveness and how they degrade. This information could help conservators restore and preserve treasured tomes for future generations. 04/25/2024 01:13 PM
