  • An expedition to a remote part of northern Australia has uncovered three new vertebrate species isolated for millions of years
  • University and a National Geographic film crew were dropped by helicopter onto the rugged Cape Melville mountain range on Cape York Peninsula
  • leaf-tail gecko, a gold-coloured skink—a type of lizard—and a brown-spotted, yellow boulder-dwelling frog, none of them ever seen before
  • ...7 more annotations...
  • The virtually impassable mountain range is home to millions of black granite boulders the size of cars and houses piled hundreds of metres high
  • Cape Melville, a plateau of boulder-strewn rainforest on top
  • a small boulder-dwelling frog, the Blotched Boulder-frog, which during the dry season lives deep in the labyrinth of the boulder-field where conditions are cool and moist
  • In the absence of water
  • tadpole develops within the egg and a fully formed frog hatches out.
  • The Cape Melville Leaf-tailed Gecko, which has huge eyes and a long, slender body, is highly distinct from its relatives
  • National Geographic, the team plans to return to Cape Melville within months to search for more new species, including snails, spiders, and perhaps even small mammals

  • SpaceX
  • has signed a contract to research, develop and test Raptor methane rocket engines at the NASA Stennis Space Center in southern Mississippi
  • plans to use the E-2 test stand at Stennis, which is able to support both vertical and horizontal rocket engine tests
  • ...10 more annotations...
  • A press release from his office said the presence of the private space company would boost jobs in the region
  • There’s little information on SpaceX’s website about what the Raptor engine is or specific development plans
  • Space News reports that it would be used for deep-space missions
  • SpaceX CEO Elon Musk has mentioned the engine previously when talking about Mars missions, according to multiple media reports
  • test the whole engine at Stennis
  • the first phase starts with the components
  • E-2 stand at Stennis is big enough for components, but we would need a bigger stand for the whole Raptor
  • reportedly hashing out a Space Act agreement to establish user fees and other parameters
  • Once that’s finished, the testing will begin, perhaps as early as next year
  • SpaceX currently does most of its rocket testing in Texas

shared by Mars Base on 01 Nov 13 - No Cached
  • first known Earth-sized planet with an Earth-like density
  • diameter of 9,200 miles,
  • is 1.2 times the size of Earth and 1.7 times more massive than Earth and it is composed of iron and rock
  • ...10 more annotations...
  • planet circles its star every eight and a half hours at a distance of less than one mile
  • one of tightest known orbit on record and due to this its formation is deemed as impossible and not suitable for life.
  • The scientists believe no planet can form so close to its star nor could it have moved to its current position.
  • Kepler-78b poses a challenge to theorists
  • When this planetary system was forming, the young star was larger than it is now.
  • the current orbit of Kepler-78b would have been inside the swollen star
  • The star of Kepler-78b is slightly smaller and less massive than the sun
  • Sun-like G-type star, which is  located 400 light-years from Earth in the constellation Cygnus
  • The exoplanet was discovered using data from NASA's Kepler Space Telescope
  • follow up observations were made using W.M. Keck Observatory atop Mauna Kea in Hawaii

  • Sometime in the next few decades, humans may be able to regrow a finger here, a toe there – and maybe even fresh patches of beating heart tissue
  • Human hearts are among the most promising targets
  • A decade ago
  • ...13 more annotations...
  • demonstrated that zebrafish had the ability to repair a badly damaged heart, thanks to a particular protein that regulates the regenerative process
  • That trick could work for humans as well as fish
  • this month, researchers from the Gladstone Institutes showed that they could turn human scar tissue into electrically conductive tissue in a lab dish by fiddling with just a few key genes
  • Among the hurdles that lie ahead: taking that technique out of the lab and applying it to living human hearts
  • humans already have demonstrated some ability to regenerate body parts
  • very young children can fill out the tips of chopped off fingers and toes
  • the salamander, which can regrow a whole arm below the joint
  • Young mice are able to regenerate toes, too
  • been studying mouse toes to understand how a similar regrowth mechanism can be reactivated or imitated in adult humans
  • In 2010, his lab showed it was possible to enhance the regenerative response in adult mice
  • researchers are cautious about predicting how studies of animal regeneration will be applied to humans
  • it's dangerous to say, 'Yes, we expect to regenerate a limb
  • the field is reaching a turning point

  • two independent research teams have now confirmed the planet’s mass and density by measuring “wobbles” of its sun-like host star, seen as the exoplanet orbits around it
  • it couldn’t have formed farther out and migrated inward, because it should have been drawn
  • straight into the star
  • ...2 more annotations...
  • more exotic possibilities is that it is the remnant core of a disrupted gas giant
  • The extreme gravitational pull from its star will draw it ever closer in, ripping the entire planet apart in about three billion years
