A PNAS study led by researchers at The University of Tokyo has produced a nearly complete genome for the Greenland shark, the longest-lived vertebrate known to science. The assembly covers 96.7 percent of its genetic material and reveals several features that could help its cells endure for centuries. The team found genetic signatures associated with…
A study in Science Advances has identified a strange class of cosmic dust that may come from a near-Earth asteroid unlike anything represented in meteorite collections. The particles, found in Antarctic samples and on urban rooftops, carry chemical fingerprints that point to a sulfur-rich parent body scientists have yet to recover as a larger meteorite.…
A study in The Journal of the Astronautical Sciences has uncovered some of the faintest debris ever detected in geosynchronous orbit. Led by researchers at the University of Warwick, the international team found tiny fragments near the orbital region used by some of Earth’s most important satellites. The objects are small, faint and easy to…
