VLT Spies Iron Raining on Ultrahot Exoplanet WASP-76b

WASP-76b, a gas-giant exoplanet located some 640 light-years away in the constellation of Pisces, has a day side where temperatures climb above 2,400 degrees Celsius (4,352 degrees Fahrenheit), high enough to vaporize metals; strong winds carry iron vapor to the cooler night side where it condenses into iron droplets. This illustration shows a night-side view of the exoplanet WASP-76b. To the left…

Mars Express Sees Intriguing Geological Features in Moreux Crater

The High Resolution Stereo Camera on ESA’s Mars Express orbiter has captured stunning images of Moreux crater, a huge impact crater in the Terra Sabaea region of the Red Planet. This image of Moreux crater comprises data gathered on October 30, 2019. Image credit: ESA / DLR / FU Berlin / CC BY-SA 3.0 IGO. When compared to other impact craters on both Mars and Earth, Moreux crater appears a little…

Study: 70 Million Years Ago Day Lasted 23.5 Hours, Year Had 372 Days

Torreites sanchezi, an extinct species of rudist clam that lived during the Cretaceous period, some 70 million years ago, grew fast, laying down daily growth rings. In a new study, a team of researchers from the Vrije Universiteit Brussel and Ghent University used lasers to sample minute slices of Torreites sanchezi’s shell and count the growth rings. The rings allowed the scientists to determine…

Biology

Researchers Create Atlas of Protein-Coding Genes in Mammalian Brain

The Brain Atlas explores the protein expression in the mammalian brain by visualization and integration of data from three species of mammals: human, pig and mouse. The open-access resource is based on the analysis of nearly 1,900 brain samples covering 27 brain regions. Genome-wide transcriptomics analysis of anatomically dissected regions in mammalian brains uncovers regional and species-specific…

New Candidate Particle for Dark Matter: D-Star Hexaquark

Dark matter is the mysterious substance that makes up roughly a quarter of the Universe. There is strong indirect evidence for its existence from measurements of cosmic primordial radiation, anomalies in the radial dependence of galactic rotational curves and gravitational lensing. Despite its apparently pivotal role in the Universe the physical origin of dark matter remains unknown. Scientists suspect…

COVID-19 Has Median Incubation Period of 5.1 Days: Study

An analysis of data on infections from the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a novel human coronavirus that causes the respiratory illness COVID-19, yielded an estimate of 5.1 days for the median disease incubation period. This median time from exposure to onset of symptoms suggests that the 14-day quarantine period used by the U.S. Centers for Disease Control and Prevention…

Genetics

DNA Analysis Reveals There Are Two Distinct Species of Red Pandas

An analysis of DNA from wild populations of the red panda (Ailurus fulgens) has found that there is not just one species but enough genetic differences to recognize two distinct species.

Archean Earth Was Covered by Global Ocean, New Study Suggests

The surface of Earth was likely covered by a global ocean 3.24 billion years ago (Archean Eon), according to a new study published in the journal Nature Geoscience.
