Mice brains wired with “competitive” neurons Researchers studying social behaviors of mice have identified that competition among the rodents was tied not only to social status but to the activation of neurons in the brain associated with feelings of ambition, decision making and rank. Results of the study, published in Nature, could be used to […]
Ancient asteroid may have carried life to Earth The chemical analysis of granular samples collected from the surface of Ruygu — an asteroid several billions of years old — revealed the presence of amino acids within the rocky terrain, which researchers believe may be responsible for the foundation of the development of life on Earth […]
DNA can store more than just genetic code A team of researchers added seven synthetic nucleobases to DNA’s current four-letter code, thereby expanding the innate ability of the double helix to store a variety of information, findings in the journal Nano Letters reveal. The study suggests this method may be a solution to sustainable data […]
Brainwave data offers clues on moment of death Data captured at the time of death of an 87-year-old epilepsy patient indicated that the human brain may be designed to coordinate the transition to death, activating brainwaves most commonly associated with memory flashbacks. “[A]lthough our loved ones have their eyes closed and are ready to leave […]
Atomic clock may help with more precise measurements Physicists have created an atomic clock that is so accurate it won’t lose a second for 300 billion years. Researchers say the clock’s precision will help them better understand difficult to measure things as gravitational waves and dark matter. Space.com Map charts Milky Way’s leftovers from galaxy […]
Ryugu sample reveals asteroid’s inner secrets Samples returned from the Ryugu asteroid by the Hayabusa2 spacecraft are yielding information about materials found just beneath the object’s surface. “The variations in physical properties among the pebbles and sand, which were not expected before spacecraft arrival at the asteroid, reflect the geological history of Ryugu,” scientists wrote […]
Chromosome study hints at early evolution of animals Chromosome changes that took place about 800 million years ago have been examined and used to find genes that may have been present in the earliest moments of animal life. Researchers viewed genomes at the chromosome level to study what they call genome tectonics to find nearly […]
Andromeda may be home to intermediate-mass black hole The nearby Andromeda Galaxy may be harboring an intermediate-mass black hole, a kind of black hole that is yet to be observed. Scientists say evidence points to an intermediate-mass black hole in the globular cluster B023-G078, which is believed to have a stripped nucleus, a condition researchers […]
Stars born from black hole seen in dwarf galaxy A supermassive black hole has been observed helping to create newborn stars in a dwarf galaxy about 34 million light-years from Earth. The stars in Henize 2-10 were seen linked to a huge gas jet coming from the black hole by the Hubble Space Telescope. Live […]
Fossil dating method points to earlier human emergence Humans were likely around about 36,000 years earlier than previously though. Researchers calculated the age of fossils found in Africa using the single crystal argon-argon dating method, analyzing pumice and ash left behind by ancient volcanic eruptions upon which the fossils were resting. Inverse Supernovas responsible for […]
