Carl Sagan detected life on Earth 30 years ago—here"s how his experiment is helping us search for alien species today
It's been 30 years since a group of scientists led by Carl Sagan found evidence for life on Earth using data from instruments on board the Nasa Galileo robotic spacecraft. Yes, you read that correctly. Among his many pearls of wisdom, Sagan was famou.....»»
Study results indicate organophosphorus flame retardants induce malformations in avian embryos
Tris(2-chloroisopropyl) phosphate (TCIPP) is one of the organophosphorus flame retardants that has been detected in the environment, and in the eggs, feathers, and liver of birds. Early developmental avian embryos are known to be sensitive to chemica.....»»
Astronomers detect most distant fast radio burst to date
An international team has spotted a remote blast of cosmic radio waves lasting less than a millisecond. This 'fast radio burst' (FRB) is the most distant ever detected. Its source was pinned down by the European Southern Observatory's (ESO) Very Larg.....»»
Scientists discover new molecule that combats viral infection in bacteria
A Ph.D. researcher at the University of St Andrews studying microbes in the human gut has discovered a new molecule that acts as a "distress signal" when viruses are detected. The research is published in the journal Nature......»»
Researchers measure magnetic field in eclipse medium of a spider pulsar PSR J2051-0827
Spider pulsars are a subclass of millisecond pulsar binary systems with low mass companions in short-period orbits. In spider pulsars, the pulsar wind and electromagnetic emission ablate and may destroy the companion......»»
Astronomers report discovery of the closest ultrastripped supernova: SN 2021agco in UGC 3855
Astronomers report the discovery of a new ultrastripped supernova in the galaxy UGC 3855. The supernova was detected using the Half Meter Telescope (HMT) at the Xingming Observatory in China. The finding was detailed in a paper published October 7 on.....»»

A fully automated process, including a brand-new artificial intelligence (AI) tool, has successfully detected, identified and classified its first supernova......»»
"All hands on deck." How Israel"s vital tech sector is navigating the war
Israel's vast tech sector has seen its fair share of crises, from financial downturns and the Covid-19 pandemic to periodic flare-ups in the Israeli-Palestinian conflict. Each time, the industry has bounced back, demonstrating why the country of just.....»»
Uncovering the secrets of spin-orbit optical Rabi oscillations
The Rabi oscillation has been proven to be one of the cornerstones of quantum mechanics, triggering substantial investigations in different disciplines including atomic and molecular physics, acoustics, and optics. Various important applications have.....»»
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.....»»
