Phonon engineering for extended lasing beyond the fluorescence spectrum
The electron and phonon are two fundamental particles (quasi-particles) of condensed matter and their interplay in single crystals can create many interesting physical phenomena, such as polaritons, charge density waves and up-conversion fluorescence.....»»
Multiple novel yeast species detected in the gut of green lacewing in Japan
Among fungi, including mushrooms and molds, there exists a wide range of yeast species that do not produce mycelium but instead grow as single cells through the processes of budding and division. Because yeasts multiply unicellularly, they are well s.....»»
Beyond the periodic table: Superheavy elements and ultradense asteroids
Some asteroids have measured densities higher than those of any elements known to exist on Earth. This suggests that they are at least partly composed of unknown types of "ultradense" matter that cannot be studied by conventional physics......»»
Starlinks are easily detected by radio telescopes
Radio astronomy and satellite communication have a long common history. Advances made in one field have benefitted the other, and our modern era of spacecraft and mobile internet is a product of this partnership. But there are times when the goals of.....»»
Researchers reveal mechanism of efficient upconversion in two-dimensional perovskite
Recently, a research team led by Prof. Liu Xinfeng from the National Center for Nanoscience and Technology (NCNST) of the Chinese Academy of Sciences (CAS) reported the efficient phonon-assisted upconversion luminescence in a quasi-two-dimensional pe.....»»
Large-scale bent radio jet detected in galaxy cluster Abell 514
Astronomers have conducted deep low-frequency radio observations of the galaxy cluster Abell 514, using the upgraded Giant Metrewave Radio Telescope (uGMRT). In their results, they detected a large-scale bent radio jet in this cluster. The finding is.....»»
Super-efficient laser light-induced detection of cancer cell-derived nanoparticles achieved
Can particles as minuscule as viruses be detected accurately within a mere five minutes? Osaka Metropolitan University scientists say yes, with their innovative method for ultrafast and ultrasensitive quantitative measurement of biological nanopartic.....»»
Scientists discover the highest energy gamma-rays ever from a pulsar
Scientists using the H.E.S.S. observatory in Namibia have detected the highest energy gamma rays ever from a dead star called a pulsar. The energy of these gamma rays clocked in at 20 tera-electronvolts, or about 10 trillion times the energy of visib.....»»

Hidden ocean the source of carbon dioxide on Jupiter moon: Research
Carbon dioxide detected on Jupiter's moon Europa comes from the vast ocean beneath its icy shell, research using James Webb Space Telescope data indicated on Thursday, potentially bolstering hopes the hidden water could harbor life......»»
Avian flu hits bird paradise of Galapagos Islands
The Galapagos National Park said Tuesday that it had detected its first cases of avian flu on the remote islands, home to unique bird species that helped inspire the theory of evolution......»»
Weakening of the relationship between winter precipitation over southern China and the Asian–Pacific Oscillation
Pacific Oscillation (APO), a dominant mode of atmospheric variability characterized by a seesaw variation in the upper-tropospheric temperature between Asia and the North Pacific, plays important roles in the atmospheric circulation and climate of Ea.....»»
New quasi-particle bridges microwave and optical domains
In a paper published today (Sept. 18) in Nature Communications, researchers from the Paul-Drude-Institut in Berlin, Germany, and the Instituto Balseiro in Bariloche, Argentina, demonstrated that the mixing of confined quantum fluids of light and GHz.....»»
