    New research looks at the possibility of moons outside our solar system causing gaps in the rings of planet J1407b. Moons orbiting planets outside our solar system could offer another clue about the pool of worlds that may be home to extra-terrestrial life, according to an astrophysicist at the University of Lincoln.

    Exoplanets are planets outside our solar system and up to this point nearly 4,000 have been discovered. Only a small proportion of these are likely to be able to sustain life, existing in what is known as the habitable zone. But some planets, especially large gas giants, may harbour moons which contain liquid water.

    Dr Sutton said: “These moons can be internally heated by the gra...

    “Biological night” is defined as the period between the onset and cessation of melatonin secretion. During this period, melatonin is secreted, blood cortisol levels rise, core body temperature goes down, and we become sleepy. Melatonin is produced only during darkness and stops upon optic exposure to bright light, with light in the blue portion of the visible spectrum proving the most potent at suppressing production. CREDIT: Angela Spivey, 10.1289/ehp.118-a28

    First-ever Spider Glue Genes Sequenced, paving way to next Biomaterials breakthrough

    Aggregate spider glue from three spider types. (A) Orb weavers coat their web’s sticky capture spiral with glue, (B) cobweb weavers cover the lower portion of their triplines with glue to create ’gumfoot’ threads, (C) the bolas spider creates a large droplet of glue specialized for capturing moths, and (D) A stretching glue droplet after contacting a probe that was subsequently withdrawn at a constant rate.

    Huge spider glue genes proved exceptionally challenging to sequence, could lead to organic pest control and more. Researchers have determined the first-ever complete sequences of two spider glue genes...

    Cool, Nebulous Ring around Milky Way’s Supermassive Black Hole

    June 7, 2019, Categories  Uncategorized

    ALMA image of the disk of cool hydrogen gas flowing around the supermassive black hole at the center of our galaxy. The colors represent the motion of the gas relative to Earth: the red portion is moving away, so the radio waves detected by ALMA are slightly stretched, or shifted, to the ‘redder’ portion of the spectrum; the blue color represents gas moving toward Earth, so the radio waves are slightly scrunched, or shifted, to the ‘bluer’ portion of the spectrum. Crosshairs indicate location of black hole.
