How does glass 'shake' and why does it start flowing when pushed hard enough?

How does glass 'shake' and why does it start flowing when pushed hard enough?

Glassy materials are everywhere, with applications far exceeding windowpanes and drinking glasses. They range from bioactive glasses for bone repair and amorphous pharmaceuticals that boost drug solubility to ultra-pure silica optics used in gravitational-wave detectors. In principle, any substance can become glass if its hot liquid is cooled fast enough to avoid forming an ordered crystal.

How quiet galaxies stay quiet: Cool gas feeds black holes in 'red geysers'

How quiet galaxies stay quiet: Cool gas feeds black holes in 'red geysers'

Astronomers have long puzzled over how some massive galaxies stop forming stars and remain dormant for billions of years—even when they still contain gas that could, in principle, fuel new stars.

Scientists find more active black holes in dwarf and Milky Way-sized galaxies by cutting through glare of star formation

Scientists find more active black holes in dwarf and Milky Way-sized galaxies by cutting through glare of star formation

Astronomers have completed the most comprehensive census of active galactic nuclei (AGN) to date, providing the clearest picture yet of the probability that galaxies of different sizes host active black holes.

Most people believe climate change primarily affects others

Most people believe climate change primarily affects others

Research conducted by researchers at the University of Gothenburg shows that people tend to rate their own risk of being affected by climate change as lower than that of others. This perception may reduce individuals' willingness to act and slow down necessary climate measures.

Hybrid parasites threaten progress against one of the world's most widespread neglected diseases

Hybrid parasites threaten progress against one of the world's most widespread neglected diseases

New research led by Liverpool School of Tropical Medicine (LSTM) warns that hybrid forms of the parasites that cause schistosomiasis are undermining existing disease control strategies and could accelerate the spread of infection in Africa and beyond.

Whale hunting began 5,000 years ago in South America, a millennium earlier than previously thought

Whale hunting began 5,000 years ago in South America, a millennium earlier than previously thought

The hunting of large whales goes back much further in time than previously thought. New research from the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB) and the Department of Prehistory of the UAB reveals that Indigenous communities in southern Brazil were hunting large cetaceans 5,000 years ago, around a thousand years before the earliest documented evidence from Arctic and North Pacific societies.

Lysosomes in focus: New study reveals how cells keep them intact

Lysosomes in focus: New study reveals how cells keep them intact

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 tiny holes in lysosomal membranes so they can be quickly repaired—a process crucial for preventing inflammation, cell death, and diseases such as Alzheimer's.
