Niels Henrik David Bohr was a Danish physicist who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922.
Unlike their ground dwelling kangaroo cousins the tree kangaroo contains some different characteristics that give these macropods the ability to live in trees. Tree kangaroos have shorter yet broader hind feet which contain longer curved nails, as well as sponge like grip on its paws and soles of its feet to enable a heightened climbing ability.
The tree kangaroo has a much larger and pendulous tail than the ground dwelling kangaroos, giving the tree kangaroo fantastic balance while swinging from trees. The male Lumholtz's tree-kangaroo averages size is about 15.6 lbs where the average female weighs in at about 13.2 lbs. The average size of a male when measure from head to the base of the tail is about 23.3 inches long with an average tail length of 27.4 inches. The average size of a female when measure from head to the base of the tail is about 21.8 inches with an average tail length of about 27.5 inches.
The tail on both the male and female of this species is the same size, if not longer than the body, proving the importance of the tail which is primarily used for balance. Tree-kangaroos do not sweat, in order to cool their bodies they lick their forearms and allow the moisture to evaporate.
They inhabit the tropical rainforests of New Guinea and far northeastern Queensland, and some of the islands in the Region.
A ten-year-old Norwegian boy who lives near Dokka, a town 110kms (68 miles) north of Oslo – put his 18-month old sister into the car sometime before 6am, while his parents were still sleeping and set off to visit his grandparents in Valdres, about 60 kilometres away.
He drove more than 10 kilometres before veering off the road, where he was found by a snowplow driver who alerted police.
Fly over the only known liquid lakes beyond Earth, courtesy of the radar aboard NASA's Cassini mission to Saturn.
This colorized movie from NASA's Cassini mission takes viewers over the largest seas and lakes on Saturn's moon Titan. The movie is made from radar data received during multiple flyovers of Titan from 2004 to 2013.
This colorized movie from NASA's Cassini mission shows the most complete view yet of Titan's northern land of lakes and seas. Saturn's moon Titan is the only world in our solar system other than Earth that has stable liquid on its surface. The liquid in Titan's lakes and seas is mostly methane and ethane.
The data were obtained by Cassini's radar instrument from 2004 to 2013. In this projection, the north pole is at the center. The view extends down to 50 degrees north latitude. In this color scheme, liquids appear blue and black depending on the way the radar bounced off the surface. Land areas appear yellow to white. A haze was added to simulate the Titan atmosphere.
Kraken Mare, Titan's largest sea, is the body in black and blue that sprawls from just below and to the right of the north pole down to the bottom right. Ligeia Mare, Titan's second largest sea, is a nearly heart-shaped body to the left and above the north pole. Punga Mare is just below the north pole.
The area above and to the left of the north pole is dotted with smaller lakes. Lakes in this area are about 30 miles (50 kilometers) across or less.

Most of the bodies of liquid on Titan occur in the northern hemisphere. In fact nearly all the lakes and seas on Titan fall into a box covering about 600 by 1,100 miles (900 by 1,800 kilometers). Only 3 percent of the liquid at Titan falls outside of this area.
Scientists are trying to identify the geologic processes that are creating large depressions capable of holding major seas in this limited area. A prime suspect is regional extension of the crust, which on Earth leads to the formation of faults creating alternating basins and roughly parallel mountain ranges. This process has shaped the Basin and Range province of the western United States, and during the period of cooler climate 13,000 years ago much of the present state of Nevada was flooded with Lake Lahontan, which (though smaller) bears a strong resemblance to the region of closely packed seas on Titan.
The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington, DC. The Cassini orbiter was designed, developed and assembled at JPL. The radar instrument was built by JPL and the Italian Space Agency, working with team members from the United States and several European countries.
Before everyone gets all giddy and crazy, keep in mind people, these are HYDROCARBON Seas. Not Water. They are completely different substances. They are literally lakes of Fuel.
Gulfstream G650: At $65 million, it's the biggest, fastest, and overall best private jet money can buy. It also takes a lot of patience to get your hands on one. Order now and you'll get your G650 in 2017. But once you're on board, you can fly around the planet faster and higher than on any commercial jet, in a cabin flooded with natural light and filled with air that is actually richer than what you breathe in cheaper planes. Whoever is buying it, it's easy to see why the G650 is so coveted. It's the largest purpose built business jet on the planet.
