Phys.org / Swapping molecular building blocks one by one reveals how receptors tell adrenaline from dopamine
Different receptors respond to different neurotransmitters or hormones, such as adrenaline involved in the fight-or-flight response, or dopamine linked to reward and motivation. Both the receptors themselves and the substances ...
Phys.org / Scientists use AI to interpret the sun's acoustic heartbeat
A new AI-based approach that can "hear" inside the sun could give vital signs of the solar disturbances that have significant effects in near-Earth space and on human activities. The solar cycle is an approximate 11-year ...
Phys.org / 'Nature's algorithm' found in Chinese money plants
Look up at the clouds. What do you see? A sailboat? A seahorse? Your great-aunt Rosemary? As humans, we're prone to seeing patterns where they don't actually exist. This behavior is so common there's a name for it: apophenia. ...
Phys.org / Molecular glue could hijack cells' natural machinery to help treat diseases
Proteins do most of the work in our body's cells. But when a protein is too active or does not function properly, it can lead to disease or other health problems. Researchers from the University of Toronto have discovered ...
Phys.org / Giving X-ray vision a sense of direction
Whether in tooth enamel or in nanomaterials made of silicon, the orientation of tiny internal structures often determines the properties of a material. A new X-ray method can even make this nano-order visible when the structures ...
Phys.org / How invading cancer cells grip and rip their way into new tissues
Researchers from the National University of Singapore (NUS) have discovered that cancer cells do not simply push through surrounding tissues to spread, but instead actively grip onto protective tissue barriers and pull them ...
Phys.org / How we feel political emotions in our bodies—and why this matters for democracy
Researchers have found our emotions toward politics not only play on our minds, but shape how our bodies respond to political experiences, even driving political participation higher. The new study, published in the Proceedings ...
Phys.org / Cold events rival heat waves in bleaching Indonesia's corals, analysis reveals
The Indonesian seas are a biodiversity hotspot, harboring the highest coral diversity in the tropics and home to an extraordinary variety of marine life. Yet these unique ecosystems have been under growing pressure for years, ...
Phys.org / DNA 'barcodes' help researchers pinpoint gold nanoparticles that can strike cancer at its power source
Researchers at the National University of Singapore (NUS) have developed a high-throughput method to identify gold nanoparticles capable of delivering therapies directly to mitochondria (the energy centers inside cancer cells). ...
Phys.org / How Qing featherwork got its colors: New scans reveal multiple birds and hidden pigment layers
The kingfisher's brilliant blue feathers were once used like paint to create works of art. The technique, known as tian-tsui, was popular during China's Qing Dynasty. And because tian-tsui uses delicate feathers, previous ...
Phys.org / Water-based nanocrystal provides a sticky solution to a pesky agricultural problem
A water-based formulation developed at the University of Waterloo using nanotechnology is both greener and more effective than conventional methods for delivering agricultural pesticides.
Phys.org / Gentle, laser-driven flows enable precise 3D imaging of delicate samples
Until now, it has been technically nearly impossible to rotate highly sensitive samples in all directions under a microscope without making contact. Researchers at the Karlsruhe Institute of Technology (KIT) have developed ...
