Volcanoes, meteorites may be tied to life’s start Meteorites and volcanoes could have produced iron particles that served as a catalyst for creating life forms on Earth. Scientists conducted experiments using metallic particles from meteorites and ash from Sicily’s Mount Etna to see how iron may have helped convert carbon dioxide and hydrogen into hydrocarbons […]
Astronomers have, for the first time, detected radio waves released by a Type Ia supernova, an explosion deriving from a white dwarf star, offering vital insights about white dwarf explosions. . A Type Ia supernova denotes the nuclear burst of a white dwarf star. This supernova category enjoys widespread recognition; astronomers employ these supernovae to […]
Simulated accretion disks may explain black hole growth Researchers using the Mega Ampere Generator for Plasma Implosion Experiments produced spinning columns that mimicked artificial accretion disks by accelerating and then colliding plasma jets. One of the research team’s primary goals is to understand how black holes are able to grow when accretion disks’ orbits stay […]
Thanks to data from a magnified, multiply imaged supernova, a team of researchers has successfully used a first-of-its-kind technique based on the Refsdal method to measure the expansion rate of the Universe. Their data provide insight into a longstanding debate in the field and could help scientists more accurately determine the Universe’s age and better […]
Human pangenome captures genetic diversity A draft human pangenome published in Nature aggregates the genomic sequences of 47 people from Africa, the Americas, Asia and Europe and captures more genetic variation than previous reference genomes have. The researchers computationally aligned the sequences to form a map with branching paths that indicate genetic variation, and the […]
Polaritons attract wide attention due to their ability to confine and guide light at the nanometre scale. These capacities are key for the development of ultrasmall resonators and waveguides that can be used for sensing, heat transfer and optical circuitry applications. But, what are polaritons in the first place? If, for the sake of the […]
Mars formations may derive from similar material Scientists who reviewed data from the Alpha Particle X-ray Spectrometer on NASA’s Opportunity rover say Mars’ Burns formation and underlying Grasberg formation may have originated from a similar source material. Dust particles or ash from volcanic eruptions may have solidified before they were blown to the site and […]
Ammonia (NH3), a ubiquitous compound, was generated in excess of 187 million tons globally in 2020. Roughly 85% is employed in the creation of nitrogenous fertilizers, while the remainder is used for refining petroleum, producing various other chemicals, and manufacturing synthetic fibers like nylon. However, these processes come with a substantial energy expenditure. Presently, the […]
Researchers compare hundreds of mammalian genomes Researchers working on the Zoonomia Project, an international study comparing the traits and genomes of some 240 mammal species, including humans, have released some of their findings in 11 papers published in Science. Researchers found conserved stretches of DNA common across species that are largely unchanged by evolution, and […]
Our modern rechargeable batteries, such as lithium-ion batteries, are anything but sustainable. One alternative is organic batteries with redox-organic electrode materials (OEMs), which can be synthesized from natural “green” materials. A Chinese team has now introduced a new OEM for aqueous organic high-capacity batteries that can be easily and cheaply recycled. Traditional inorganic electrode materials […]
