BionicKangaroo

Robotic recreation of the Kangaroo form put together by Festo to demonstrate energy-efficient movement (this was initially announced on April the 1st, but turns out to be real) - video embedded below:

With the BionicKangaroo, Festo has technologically reproduced the unique way a kangaroo moves. Like its natural model, it can recover the energy when jumping, store it and efficiently use it for the next jump.

On the artificial kangaroo, Festo intelligently combines pneumatic and electrical drive technology to produce a highly dynamic system. The stable jump kinematics plus the precise control technology ensure stability when jumping and landing. The consistent lightweight construction facilitates the unique jumping behaviour. The system is controlled by gestures.

#EarthDay: Mount Nyiragongo is a stratovolcano situated in the Virunga Mountains of the Albertine Rift inside Virunga National Park, in the Democratic Republic of the Congo. The volcano has an elevation of 3,470 m (11,385 ft).
The main crater is about two km wide and usually contains a lava lake (see photo) that has at times been the most voluminous known lava lake in recent history. The depth of the lava lake varies considerably. Not much is known about how long the volcano has been erupting, but since 1882, it has erupted at least 34 times with the two most recent eruptions occurring in 1977 and 2002, both resulting in destruction of nearby human habitats and loss of lives, mostly due to asphyxiation by carbon dioxide.
Activity at Nyiragongo is ongoing, but currently confined to the crater.
Nyiragongo and nearby Nyamuragira are together responsible for 40% of Africa’s historical volcanic eruptions.
The Democratic Republic of Congo is home to a total of five different active and extinct volcanoes.

How many Earth twins are out there? Hundreds possibly

NASA’s recent discovery of Kepler-186f, the first habitable Earth-sized planet is big news in humankind’s long search for extraterrestrial life.

A universe full of exoplanets: Thanks to the Kepler Space Telescope, which was launched in 2009 to hunt planets across the universe, we’ve managed to find around 1800 exoplanets so far, many of which have been discovered in just the last year or so.

  Sharpless 308: Star Bubble   Image Credit & Copyright:  Jeff Husted
 Explanation:  Blown by fast winds from a hot, massive star, this cosmic bubble is huge. Cataloged as Sharpless 2-308 it lies some 5,200 light-years away toward the constellation of the Big Dog (Canis Major) and covers slightly more of the sky than a Full Moon. That corresponds to a diameter of 60 light-years at its estimated distance. The massive star that created the bubble, a Wolf-Rayet star, is the bright one near the center of the nebula. Wolf-Rayet stars have over 20 times the mass of the Sun and are thought to be in a brief, pre-supernova phase of massive star evolution. Fast winds from this Wolf-Rayet star create the bubble-shaped nebula as they sweep up slower moving material from an earlier phase of evolution. The windblown nebula has an age of about 70,000 years. Relatively faint emission captured in the expansive image is dominated by the glow of ionized oxygen atoms mapped to violet hues.

How astronomers learn the masses of double stars
For astronomers, a binary or double star is a gift from the heavens. Astronomers observe these stars to find telltale clues to each star’s mass.
Fortunately for astronomers, there are lots of binaries – two stars revolving around a common center of mass – populating the starry sky. A binary system is literally a gift from the heavens because it reveals to astronomers the masses of its two component stars.

Dermatographic urticaria (also known “skin writing”) is a skin disorder seen in 4–5% of the population and is one of the most common types of urticaria in which the skin becomes raised and inflamed when stroked, scratched, rubbed, and sometimes even slapped.

The symptoms are thought to be caused by mast cells in the surface of the skin releasing histamines without the presence of antigens, due to the presence of a weak membrane surrounding the mast cells. This weak membrane easily and rapidly breaks down under physical pressure causing an allergic-like reaction.
