Phys.org / Planets without plate tectonics and too little carbon dioxide could mean that technological alien life is rare
The closest technological species to us in the Milky Way galaxy could be 33,000 light years away and their civilization would have to be at least 280,000 years, and possibly millions of years, old if they are to exist at ...
Phys.org / Ditches as waterways: Managing 'ditch-scapes' to strengthen communities and the environment
Ditches are all around: along roads, through neighborhoods, across fields and marshes. These human-made waterways are so common that they can be easy to miss. A new literature review published in Communications Earth & Environment ...
Phys.org / Models explain mysterious feature controlling magnetic properties of the sun
In the late 1980s, scientists realized they could understand the interior properties of the sun by observing the sound waves that resonate inside it. This technique, called helioseismology, revealed a mysteriously thin dynamical ...
Phys.org / Laser reveals sound from supersonic molecules in near-space cold conditions
What happens when you hurl molecules faster than sound through a vacuum chamber nearly as cold as space itself? At the University of Missouri, researchers are finding out—and discovering new ways to detect molecules under ...
Phys.org / Researchers reveal molecular assembly and efficient light harvesting of largest eukaryotic photosystem complex
Coccolithophores are a type of single-celled microalgae that fix CO2 into organic matter and precipitate calcium carbonate, profoundly shaping ocean optics, carbon export, and long-term carbon storage. They are major contributors ...
Phys.org / How lactate defends cells under stress
Many people are familiar with lactate primarily from sports, where it is produced in muscle cells during physical exertion. However, the molecule could also play an important role in other cell types.
Phys.org / Dallas scientist wins 'America's Nobel' for research into 'ugly duckling' proteins
More than a decade ago at UT Southwestern, scientist Steven McKnight chased a compound that turns stem cells into beating heart muscle.
Phys.org / Atom-thin crystals provide new way to power the future of computer memory
Picture the smartphone in your pocket, the data centers powering artificial intelligence, or the wearable health monitors that track your heartbeat. All of them rely on energy-hungry memory chips to store and process information. ...
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 / Uniting the light spectrum on a single microchip
Focused laser-like light that covers a wide range of frequencies is highly desirable for many scientific studies and for many applications, for instance, quality control of manufacturing semiconductor electronic chips. But ...
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 ...
