Phys.org / How redox reactions drive bacteria's Na⁺-NQR sodium pump
The enzyme Na⁺-NQR is a sodium pump that drives the respiration of many marine and pathogenic bacteria. Using redox reactions, the process of exchanging electrons between materials, it powers the transportation of sodium ...
Phys.org / Mira A ejects seven Earth masses, forming a heart-shaped cloud 300 light-years away
Just in time for Valentine's Day, space offers a heart-shaped greeting. The star Mira A, about 300 light-years from Earth, has released material into an expanding cloud of gas and dust resembling a heart. Both the amount ...
Tech Xplore / AI-powered digital twin enables real-time energy evaluation for smart buildings
In the context of global decarbonization, reducing energy consumption in the building sector is an urgent issue. Researchers have developed a next-generation building energy evaluation model that combines rule-based symbolic ...
Phys.org / Webb unveils nature of distant ultraviolet-luminous galaxy CEERS2-588
Astronomers from the University of Tokyo in Japan and elsewhere have employed the James Webb Space Telescope (JWST) to observe a distant ultraviolet-luminous galaxy known as CEERS2-588. Results of the observational campaign, ...
Phys.org / Bacterial hitchhikers can give their hosts super strength
A Dartmouth study finds that molecular hitchhikers living within bacteria can make their hosts extra resistant to medical treatment by corralling them into tightly packed groups. The findings introduce a previously unknown ...
Phys.org / Unseen planet or brown dwarf may have hidden 'rare' fading star
One of the longest stellar dimming events ever observed was likely caused by the gigantic saucer-like rings of either an unseen brown dwarf or "super-Jupiter" blocking its host star's light, astronomers say. For decades, ...
Phys.org / Extinct Hawaiian ibis with strangely small eyes suggests a shift to nocturnal life
Islands are famous for producing some of the world's strangest creatures, and now a new international study shows that the evolution of bird species on Hawaiian islands includes an ibis with unusually small eyes and limited ...
Phys.org / Visualizing how a plant's leaves, stem and roots mutually communicate under environmental stress in real time
How do the different parts of an adult plant communicate with each other when it suffers an injury, is waterlogged, burnt or exposed to environmental stress? Today we can answer this question thanks to an innovative optical ...
Medical Xpress / Early-life indoor mold linked to reduced childhood lung function, long-term study finds
Mold is a silent threat, often going unnoticed as it quietly harms health. What's concerning is that exposure to mold during early childhood leaves its mark way into adolescence. In a study published in Environmental Research: ...
Phys.org / New research uncovers how microbes shape ecosystem resilience
Most people think of microbes in simple terms: Some make you sick, while others help keep you healthy. But microbes' influence stretches far beyond human bodies. These astonishingly complex organisms regulate the health of ...
Phys.org / New lithium-based green phosphors rival today's commercial LED standard
Research results from Innsbruck, Schwabmünchen, and Düsseldorf demonstrate how the most widely used green phosphors in commercial LEDs can be replaced by representatives of an entirely new class of compounds. Green luminescence, ...
Phys.org / Europe's most powerful rocket carries 32 satellites for Amazon Leo network into space
The most powerful version of Europe's Ariane 6 rocket Thursday carried 32 satellites into space for the Amazon Leo network, which aims to rival Elon Musk's Starlink.
