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 / 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 / Quick course correction needed to avoid 'hothouse Earth' scenario, scientists say
Scientists say that multiple Earth system components appear closer to destabilization than previously believed, putting the planet in increased danger of following a "hothouse" path driven by feedback loops that can amplify ...
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 / Majorana qubits become readable as quantum capacitance detects even-odd states
The race to build reliable quantum computers is fraught with obstacles, and one of the most difficult to overcome is related to the promising but elusive Majorana qubits. Now, an international team has read the information ...
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 ...
Phys.org / Seeing how atoms vibrate at the Ångström scale
Probing the vibration of atoms provides detailed information on local structure and bonding that define material properties. Tip-enhanced Raman spectroscopy (TERS) offers extremely high resolution to probe such vibrations. ...
Phys.org / Scientists reveal formation mechanism behind spherical assemblies of nanocrystals
From table salt to snowflakes, and from gemstones to diamonds—we encounter crystals everywhere in daily life, usually cubic (table salt) or hexagonal (snowflakes). Researchers from Noushine Shahidzadeh's group at the UvA ...
Phys.org / A new framework could transform national flood prediction
When severe weather strikes, the National Weather Service's (NWS) Office of Water Prediction (OWP) makes critical flood forecasts with the National Water Model. Despite improvements over time, the model's performance has ...
Phys.org / Mars' 'young' volcanoes prove more complex than scientists once thought
What appears to be a single volcanic eruption is often the result of complex processes operating deep beneath the surface, where magma moves, evolves, and changes over long periods of time. To fully understand how volcanoes ...
Phys.org / AI method accelerates liquid simulations by learning fundamental physical relationships
Researchers at the University of Bayreuth have developed a method using artificial intelligence that can significantly speed up the calculation of liquid properties. The AI approach predicts the chemical potential—an indispensable ...
Phys.org / Space mining without heavy machines? Microbes harvest metals from meteorites aboard space station
If humankind is to explore deep space, one small passenger should not be left behind: microbes. In fact, it would be impossible to leave them behind, since they live on and in our bodies, surfaces and food. Learning how they ...
