A recent paper in Science authored Ilya Bobrovskiy, Janet Hope and colleagues from ANU, the Russian Academy and European institutions has remarkably (and convincingly) discovered molecules of fat in Dickinsonia, a marine genus of the Ediacaran biota. This has confirmed that the 558 million year old Dickinsonia is the earliest animal in the geological record and maybe »
Jupiter as seen from the Juno spacecraft. NASA/JPL-Caltech/SwRI/MSSS/Gabriel Fiset A complex dynamo inferred from the hemispheric dichotomy of Jupiter’s magnetic field The Juno spacecraft, which is in a polar orbit around Jupiter, is providing direct measurements of the planet’s magnetic field close to its surface. A recent analysis of observations »
This spectacular image of Dione and Saturn’s rings is simply fantastic. Dione is a small moon with a diameter of 1,120 km, surface gravity of 0.232 m/S2 and semi-major axis similar to that of Earth’s moon. Its orbital period is only 2.7 days however, 10% of our moon, reflecting the »
To understand Trump (and a sizeable portion of the entrepreneur class) you only need one photograph and this is the one. His level of trait Agreeableness is exceedingly low. Sub traits Compassion and Politeness are without question in the zero percentile. What does that mean? If there were 100 people »
200 AMU macromolecular organics detected in plumes on Enceladus Cassini was intentionally crashed into the atmosphere of Saturn late in 2016, to avoid contamination of any of the moons of the planet. While that ended data collection from Saturn and its moons, data analysis continues to produce surprises. Saturn’s moon »
As can be seen in the above graphic, isotopic data derived from ice-cores, deep-sea sediment sediments and other proxies shows dramatic and a characteristic “saw-tooth” signature over the Pleistocene (1.2 million years). For a compilation of the same oxygen isotope and other data over the last 2.7 million years (which »
Saturn’s moons Tethys (in the foreground) & Janus (small irregular moon in the background) – Courtesy Cassini spacecraft – nasa.govThe view was obtained at a distance of approximately 593,000 miles (955,000 kilometres) from Janus. Image scale at Janus is 3.7 miles (6 kilometres) per pixel. Tethys was at a distance »
Shenshen Lai and colleagues from the University of British Columbia report results from a study of protein kinases in eukaryotes (A eukaryote is any organism whose cells contain a nucleus and other organelles enclosed within membranes. Protein kinases play a pivotal role in communicating intracellular signals in eukaryotes. The family of eukaryotic »
