Phys.org / Stellar collisions may have been common when the universe was young
In our solar system's corner of the galaxy, stars rarely collide. It makes sense: Space is vast, and stars have room to roam. Even in most of the present-day universe, stellar collisions are rare. The James Webb Space Telescope, ...
Phys.org / Metalens microscope switches focus with voltage, not moving optics
Just as it is difficult for a camera to keep both a nearby flower and a distant mountain sharply focused at the same time, conventional optical microscopes face a similar challenge when imaging structures located at different ...
Phys.org / One extra quantum dot helps balance speed and stability in spin qubits
Quantum computers need qubits that can be controlled both quickly and reliably. Yet making semiconductor spin qubits faster often makes them more sensitive to electrical noise, creating a difficult trade-off.
Phys.org / False lingzhi unmasked: Scientists crack the 245-year mystery behind a medicinal mushroom mix-up
In a new study published today in Plants, People, Planet, scientists from the Royal Botanic Gardens, Kew, and their international collaborators clarify the distinction between Ganoderma lucidum, a European bracket fungus ...
Phys.org / RNA archiving method reveals what a cell did days ago
Information on what a cell did a few hours or days ago is generally unavailable to researchers, who can only measure the cell's current status. This is a problem if the aim is to understand how immune responses arise or why ...
Phys.org / Ahead of their time: Restricted to pre-2018 research, AI flags hydrogen catalyst reported in later experiments
Researchers have used artificial intelligence to identify promising catalysts using only the scientific knowledge that was available years before their actual discovery. Their findings could accelerate the search for more ...
Phys.org / Sediment core reveals volcanic eruption preceded ancient cold spell by about 150 years
A new study led by an international research team including scientists at the University of South Carolina challenges the idea that the ancient Laacher See volcanic eruption in western Europe triggered a significant climate-cooling ...
Phys.org / Hidden chromosome structures reveal greater complexity in how roundworms organize DNA
Almost every cell in our body contains around two meters (6.6 feet) of DNA, packed into a tiny nucleus. Yet for the cell to function, this enormous amount of genetic material must remain organized and accessible. Researchers ...
Phys.org / New binary gene expression system enables independent control of multiple cell types
Our bodies are composed of many different types of cells that work together to build and maintain normal physiological functions. In the central nervous system, for example, neurons transmit information, while glial cells ...
Phys.org / Britain's 1972 school reform may have lowered dementia diagnoses half a century later
A new study provides perhaps the strongest evidence yet that education can help mitigate long-term dementia risk.
Phys.org / Silent bacterial genes yield potential leads for future cancer drugs
Natural products produced by microorganisms are a promising source of new drugs. Researchers at the Helmholtz Center for Infection Research (HZI) and its Saarbrücken-based site, the Helmholtz Institute for Pharmaceutical ...
Dialog / Could ecological roles offer clues to how life began?
Producers, consumers, and decomposers play different roles in today's ecosystems. Thinking about these familiar roles led me to a question: Could their differences partly reflect the different physical and chemical environments ...
