Researchers develop novel multi-sensor data fusion methods for rapid and accurate compound fertilizer quality detection
In a study published in Talanta, a research team led by Prof. Wu Yuejin from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has developed a data fusion strategy based on near-infrared spectroscopy (NIRS) and laser-induced.....»»
Curving light in a record-setting way
A team led by scientists and engineers from the University of Wisconsin-Madison, the University of Southern California and Washington University in St. Louis, has created a unique, record-setting material that can bend one infrared ray of light in tw.....»»
The revisited mass of the Milky Way is much smaller than expectations from cosmology
Thanks to the latest Gaia satellite catalog from the European Space Agency (ESA), an international team led by astronomers from the Paris Observatory–PSL and the CNRS has achieved the most accurate measurement of the mass of the Milky Way. This stu.....»»
Gaia is now finding planets—could it find another Earth?
The ESA launched Gaia in 2013 with one overarching goal: to map more than one billion stars in the Milky Way. Its vast collection of data is frequently used in published research. Gaia is an ambitious mission, though it seldom makes headlines on its.....»»
Widespread iPhone 15 overheating reports, with temperatures as high as 116F
Widespread reports are circulating about the iPhone 15 overheating, seemingly across all models. Measurements taken with an infrared camera show temperatures as high as 116F. The issue appears to affect all four iPhone 15 models, with some owners.....»»
Astronomers find abundance of Milky Way–like galaxies in early universe, rewriting cosmic evolution theories
Galaxies from the early universe are more like our own Milky Way than previously thought, flipping the entire narrative of how scientists think about structure formation in the universe, according to new research published today......»»
We should be looking for small, hot Dyson spheres, new paper argues
In 1960, legendary physicist Freeman Dyson published his seminal paper "Search for Artificial Stellar Sources of Infrared Radiation," wherein he proposed that there could be extraterrestrial civilizations so advanced that they could build megastructu.....»»
Material would allow users to "tune" windows to block targeted wavelengths of light
Researchers have demonstrated a material for next generation dynamic windows, which would allow building occupants to switch their windows between three modes: transparent, or "normal" windows; windows that block infrared light, helping to keep a bui.....»»
Copper-infused nanocrystals boost infrared light conversion
Sunlight is an inexhaustible source of energy, and utilizing sunlight to generate electricity is one of the cornerstones of renewable energy. More than 40% of the sunlight that falls on Earth is in the infrared, visible and ultraviolet spectra; howev.....»»
Motion of stars near Milky Way"s central black hole is only predictable for a few hundred years
The orbits of 27 stars orbiting closely around the black hole at the center of our Milky Way are so chaotic that researchers cannot predict with confidence where they will be in about 462 years. This finding emerges from simulations by three astronom.....»»
Hubble dispels dust to see glittering globular cluster Terzan 12
The glittering globular cluster Terzan 12—a vast, tightly bound collection of stars—fills the frame of this image from the NASA/ESA Hubble Space Telescope. The location of this globular cluster, deep in the Milky Way galaxy in the constellation S.....»»
How do you weigh a star? Masses of RR Lyrae stars revealed through their pulsations
RR Lyrae stars are old, pulsating stars that burn helium in their cores for fuel. Their progenitors were similar to our sun, but they are now much larger and brighter than our sun. We know of hundreds of thousands of RR Lyrae stars within the Milky W.....»»
Making the invisible, visible: New method makes mid-infrared light detectable at room temperature
Scientists from the University of Birmingham and the University of Cambridge have developed a new method for detecting mid-infrared (MIR) light at room temperature using quantum systems......»»
Bioactive near-infrared II clusters for 3D imaging and acute inflammation inhibition
The bioactivity of most near-infrared II (NIRII) fluorophores are limited, thereby conflicting the achievement of strong fluorescence and high catalytic activities, due to a lack of free electrons in the method......»»
How Seeing the Milky Way Helped Us Discover the Whole Universe
Marvel for a moment at the Milky Way’s night-sky spectacle—and the scientific revolutions it has sparked.....»»
