Science:NGC 2207: Colliding Galaxies [Ultra HD]

April 23, 2018

NGC 2207 is a pair of colliding spiral galaxies. Their bright central nuclei resemble a striking set of eyes. In visible light, trails of stars and gas trace out spiral arms, stretched by the tidal pull between the galaxies. When seen in infrared light (IR), the glow of warm dust appears. This dust is the raw material for the creation of new stars and planets. Complementary to the IR, the X-ray view reveals areas of active star formation and the birth of super star clusters. Though individual stars are too far apart to collide, the material between the stars merges to create high-density pockets of gas. These regions gravitationally collapse to trigger a firestorm of starbirth. The galaxy collision will go on for several millions of years, leaving the galaxies completely altered in terms of their shapes. Video Credit: NASA, ESA, and G.

Science:Tonight’s Sky: May 2018

April 20, 2018

In May, the stars and galaxies of Virgo and Canes Venatici, the full disc of Jupiter, and the Eta Aquarid meteor shower are all on view in the Northern Hemisphere. “Tonight’s Sky” is produced by HubbleSite.org, online home of the Hubble Space Telescope. This is a recurring show, and you can find more episodes—and other astronomy videos—at hubblesite.org/videos/science

Male contraceptive successfully stops sperm without affecting hormones in monkeys.

April 20, 2018

Men have two practical choices for contraception; the condom which has a high typical use failure rate of approximately 18% or vasectomy which is expensive and not readily reversible.  Now, a study from researchers led by the University of North Carolina shows how a compound called EP055 binds to sperm proteins to significantly slow the overall mobility of the sperm Read more

Science:Sculpture Garden of Gas and Dust: Core of the Lagoon Nebula

April 19, 2018

This video zooms into the core of a rich star-birth region called the Lagoon Nebula, located in the constellation Sagittarius in the direction of our Milky Way galaxy’s central bulge. The sequence then dissolves to a series of imagined three-dimensional flights past striking structures of this gaseous landscape. Viewers examine dark, dusty clouds silhouetted against a colorful background of luminous gas that has been heated by a massive star. Pillars of dense gas and bow shocks around newborn stars are shaped by the strong winds from the brightest stars. The intense high-energy emission from these same stars creates the glowing ridges of gas in ionization fronts. These features are some of the highlights of this vibrant region where new stars and planets are born. Credit: NASA, ESA, and G. Bacon, D. Player, J. DePasquale, F. Summers, and Z.

Researchers identify precision medicine-based power switch for muscles.

April 13, 2018

It is known that strenuous exercise translates into better endurance, however, it is unclear in precision medicine terms which specific proteins trigger the health benefits gained through exercising.  Now, a study from researchers at Salk Institute shows that a protein known as ERRγ (ERR gamma) helps make endurance exercise possible by gearing up the energy-creating cellular power plants known as Read more
