When the cell's recycling stations, the lysosomes, start leaking, it can become dangerous. Toxic waste risks spreading and damaging the cell. Now, researchers at Umeå University have revealed the molecular sensors that detect ...

In a study published in Science, researchers have resolved, for the first time, the high-resolution crystal structure of the complex formed between the NodD protein of pea rhizobia and a flavonoid compound (hesperetin). They ...

Ceratopsians were horned, beaked dinosaurs that once stomped their way all over North America and Asia during the Late Cretaceous period, about 80 million years ago. Their abundance in the fossil records of these continents, ...

Astronomers using W. M. Keck Observatory on Maunakea, Hawaiʻi Island have uncovered the largest and most extended stream of super-heated gas ever observed flowing from a nearby galaxy, providing the clearest evidence yet ...

A new Curtin University-led study has shed new light on the widespread number of households in developing countries burning plastic as an everyday energy source, uncovering serious international health, social equality and ...

Using the upgraded Giant Metrewave Radio Telescope (uGMRT), Indian astronomers have performed multi-frequency observations of a repeating fast radio burst designated FRB 20201124A. Results of these observations shed more ...

A group of scientists, including Sergey Frolov, professor of physics at the University of Pittsburgh, and co-authors from Minnesota and Grenoble have undertaken several replication studies centered around topological effects ...

Extreme weather events have become significantly more common in the Arctic over recent decades, posing a threat to vital polar ecosystems, according to new research by an international team of scientists.

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have uncovered previously unobserved oscillation states—so-called Floquet states—in tiny magnetic vortices. Unlike earlier experiments, which required energy-intensive ...

Scientists at the University of Colorado Boulder may have solved a pressing mystery about the universe's gravitational wave background.

For the first time, scientists have answered a longstanding question in cell biology about a partnership of proteins called the "KICSTOR–GATOR1 complex" which operates as a control system inside our cells, telling them ...

To ensure that the tissue structures of biological samples are easily recognizable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is uranyl acetate. However, some ...
