Phys.org / Stored for 130 years: Bottles reveal evidence of Danish butter production and hygiene practices of the past
Two forgotten bottles in a basement in Frederiksberg containing bacterial cultures from the 1890s have provided researchers at the University of Copenhagen with unique insight into Denmark's butter production history. Using ...
Phys.org / Fluorescent 'zoom lens' exposes hidden protein changes for earlier disease detection
A novel strategy developed at Rice University allows scientists to zoom in on tiny segments of proteins inside living cells, revealing localized environmental changes that could indicate the earliest stages of diseases such ...
Phys.org / Nanoscale images of protein complex reveal secret to blood clotting chain reaction
If you've ever accidentally sliced yourself on broken glass or a piece of paper, you may have noticed that the bleeding can be hard to stop. Scientists have long wondered how the cascade of events that leads to blood clotting ...
Phys.org / Amino acids act as 'anti-salt': New insight into how small molecules stabilize proteins
Biologists have long known that amino acids can help stabilize proteins, for example as additives to pharmaceutical formulations. In trying to understand why this works, EPFL and MIT researchers have discovered a fundamental ...
Phys.org / Survey across the Global South sheds new light on support for climate policies
A new study, published in Nature Climate Change, offers a comprehensive picture of public attitudes toward climate policies, such as carbon taxes, in seven large countries in the Global South: Chile, Colombia, India, Kenya, ...
Phys.org / Discovery of new moon or ring system orbiting mysterious distant planet Quaoar
Astronomers have discovered what they think may be another moon orbiting a distant dwarf planet called Quaoar. This small, icy, egg-shaped planet in the far reaches of our solar system, beyond Neptune, is already known to ...
Phys.org / Pinning down protons in water—a basic science success story
The movement of protons through electrically charged water is one of the most fundamental processes in chemistry. It is evident in everything from eyesight to energy storage to rocket fuel—and scientists have known about ...
Phys.org / QROCODILE experiment advances search for dark matter using superconducting nanowire single-photon detectors
Over the past decades, many research teams worldwide have been trying to detect dark matter, an elusive type of matter that does not emit, reflect or absorb light, using a variety of highly sensitive detectors. Ultimately, ...
Phys.org / Dandelions control the dispersal of their seeds through asymmetrical attachment, finds study
Don't be disappointed if all the fluffy seeds of a dandelion don't fly away with a single blow. The gust of wind from your lungs may be strong, but the dandelion's natural desire to control how its seeds are dispersed is ...
Phys.org / Second exoplanet found orbiting nearby star Gliese 536
Using radial velocity measurements, an international team of astronomers has identified a second planet orbiting a nearby M-dwarf star known as Gliese 536. The newfound alien world turns out to be at least a few times more ...
Phys.org / What 3I/ATLAS tells us about other solar systems
The earliest images of 3I/ATLAS, newly uncovered by Michigan State University, reveal how the interstellar object evolved as it traveled through our solar system—and how other distant solar systems might be different from ...
Phys.org / Measuring the Unruh effect: Proposed approach could bridge gap between general relativity and quantum mechanics
Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their novel approach opens ...
