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

    June 7, 2019, Categories  Uncategorized

    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glue specialized for capturing moths, and (D) A stretching glue droplet after contacting a probe that was subsequently withdrawn at a constant rate.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.

    Solving the Sun’s Super-Heating Mystery with Parker Solar Probe

    June 6, 2019, Categories  Astronomy/Space

    Initially, Kasper didn’t think to compare his estimate of the zone’s location with the Alfvén point, but he wanted to know if there was a physically meaningful location in space that produced the outer boundary.

    It’s one of the greatest and longest-running mysteries surrounding, quite literally, our sun – why is its outer atmosphere hotter than its fiery surface? University of Michigan researchers believe they have the answer, and hope to prove it with help from NASA’s Parker Solar Probe.

    In roughly two years, the probe will be the first human-made craft to enter the zone surrounding the sun where heating looks fundamentally different that what has previously been seen in space...

    A Treasure Map to understanding the Epigenetic causes of disease

    Researchers have identified special regions of the genome where a blood sample can be used to infer epigenetic regulation throughout the body, allowing scientists to test for epigenetic causes of disease. Epigenetics is a system for molecular marking of DNA – it tells the different cells in the body which genes to turn on or off in that cell type. But the cell-specific nature of epigenetics makes it challenging to study. Whereas a blood sample can be used to ‘genotype’ an individual, most epigenetic marks in blood DNA provide no clues about epigenetic dysregulation in other parts of the body, such as the brain or heart.
