Science:HH 901: Pillars in the Carina Nebula [Ultra HD]

April 11, 2018

Herbig Haro 901 is an immense pillar of gas and dust inside the Carina Nebula, a huge star-forming region in our galaxy. The pillar is several light-years tall and contains a few massive young stars. They shoot out powerful jets that emerge from the cloud. In some cases, the jets create bow-shock patterns similar to the effects of a ship plowing through the ocean. In the visible-light view, very few stars can be seen because the gas and dust block starlight. But in the infrared view, stars become visible and numerous. The visible-light colors emerge from the glow of different gases: oxygen (blue), hydrogen/nitrogen (green), and sulfur (red). The Carina Nebula is approximately 7,500 light years from Earth.

Cat-like ‘hearing’ for the augmented human with device at smallest scale yet.

April 6, 2018

Human augmentation is the attempt to temporarily or permanently enhance the human body through natural or artificial means.  More commonly cybernetics and/or enabling human-computer interfaces are used to enhance the body and mind.  However, human augmentation is also being supplemented by evolving basic technologies combining sensors, wearable computing, the Internet of Things, and artificial intelligence.  Now, a study from researchers Read more

Science:The Plumes of Europa: Ice, Water, Life?

April 4, 2018

The Plumes of Europa: Ice, Water, Life? Susana Deustua, Space Telescope Science Institute Europa is one of the four moons of Jupiter discovered by Galileo in 1610. Four hundred years later, the Voyager and Galileo space probes took stunning images of Europa, revealing an icy surface crisscrossed by linear fractures. Four years ago, astronomers using the Hubble Space Telescope found evidence for plumes of water emerging from Europa’s icy surface. Ultraviolet spectroscopy detected emission indicative of water, and ultraviolet imaging of Europa as it transits Jupiter showed absorption patches suggestive of plumes. If there is liquid water on Europa, will future missions to Europa find evidence of life? Host: Dr. Frank Summers Recorded live on Tuesday, April 3 at the Space Telescope Science Institute in Baltimore, Maryland, U.S.A. For more information: hubble.stsci.edu/about_us/public_talks/

Microglia filmed shaping synapses for the first time.

March 30, 2018

It is now that around one in ten cells in the human brain are microglia, which act as the first and main contact in the central nervous system’s active immune defense and guide healthy brain development. Researchers have proposed that microglia pluck off and eat synapses, connections between brain cells, as an essential step in the pruning of connections during Read more
