Phys.org / Male green hermit hummingbirds: Bills evolved for battle
Let's get one thing out of the way: All hummingbirds fight. Most species fight for food, using their tiny bodies and sharp bills to force competitors away from flowers. But the green hermit hummingbird, which lives primarily ...
Phys.org / Why some volcanoes don't explode
The explosiveness of a volcanic eruption depends on how many gas bubbles form in the magma—and when. Until now, it was thought that gas bubbles were formed primarily when the ambient pressure dropped while the magma was ...
Phys.org / Synthesizing stable, open-chain amines with nitrogen-based chirality
A research team from Prof. Benjamin List's department at the Max Planck Institut für Kohlenforschung has solved a long-elusive riddle of chemistry: the synthesis of stable, open-chain amines that carry their chirality on ...
Phys.org / Protein droplets in the nucleus guard against cancer, researchers discover
Scientists at the Nano Life Science Institute (WPI-NanoLSI), Kanazawa University, have discovered how a gene-regulating protein forms tiny liquid-like droplets inside the cell nucleus (the compartment that stores and manages ...
Phys.org / Sea level rise threatens the North Sea coast more than expected
As a result of climate change, rising sea levels are threatening low-lying coastal areas around the world, such as the Wadden Sea in the North Sea. Tidal basins form a natural protective barrier there. They connect the mainland ...
Phys.org / Earth's crust under stress: Researchers decipher energy release during earthquakes
Why do some earthquakes release more energy than others? A research team led by Prof. Dr. Armin Dielforder from the University of Greifswald has managed to demonstrate a clear physical connection between the energy released ...
Phys.org / Genetic engineering reduces plant's chromosome number without affecting its growth
Higher yields, greater resilience to climatic changes or diseases—the demands on crop plants are constantly growing. To address these challenges, researchers of Karlsruhe Institute of Technology (KIT) are developing new ...
Phys.org / Discovery of plant reproductive success provides insights into human fertility
Researchers have uncovered how successful chromosome segregation during sexual reproduction is achieved in plants. The discovery, by scientists led by the University of Leicester, could be beneficial for both plant breeding ...
Phys.org / Reed leafhopper's diverse microbes fuel its rise as a major crop pest
The reed leafhopper (Pentastiridius leporinus) was originally a specialist, limited exclusively to reed grass as a food source. Within a few years, however, it developed into a dangerous pest that attacks not only reed grass ...
Phys.org / When the air gets dry, cockroaches cuddle: Study reveals survival strategy
When conditions get too dry, Madagascar hissing cockroaches like to "cuddle." Under certain conditions, the large insects gather in groups, with many participants in physical contact with one another. According to recent ...
Phys.org / Physicists explore optical launch of hypersound pulses in halide perovskites
A German-French team of physicists from TU Dortmund University, University of Würzburg, and Le Mans Université has succeeded in launching shear hypersound pulses with exceptionally large amplitudes in metal halide perovskites ...
Phys.org / G protein simulations reveal how a critical signaling step works inside cells
UNC researchers discovered how a key step in cell signaling works by showing exactly how G proteins detach from receptors that many common medicines target.
