    Interesting, decent theory. .. A sprout that small might not be thick enough to use as a trap...more mature trees would be used, the bend shown in the pictures may be much higher.
    But my eyes ain't what they used to be, i see more clearly now with age.

    Trees of all sizes can be used...even small young saplings you can bend easy can catch rabbits/squirrrels/racoons etc...

    Europa! - That planet we all have eyes for is in the news again. NASA has announced "evidence of surprising activity" - and a spoiler saying its NOT aliens. Probably more evidence of an ocean under the ice. NASA plans on sending a probe/s to first parachute down to the icy surface then transform into a drill and drill down through the ice and then transforming again to become a submersible...a couple of flood lights and a big ass camera to see what their is to see in the sea of Galalea (what I think they should call it). Would we see something staring back? Probably not, with light being almost if not entirely not present I doubt any "creatures" would bother with eyes...I think this planet is destined to become a major base for humans in the next 500 years.

    Zooming in on Star Cluster Terzan 5
    [media]https://www.youtube.com/watch?v=jtQOAtiJq3o[/media]

    Globular clusters once ruled the Milky Way. Back in the old days, back when our Galaxy first formed, perhaps thousands of globular clusters roamed our Galaxy. Today, there are less than 200 left. Over the eons, many globular clusters were destroyed by repeated fateful encounters with each other or the Galactic center.
    Surviving relics are older than any Earth fossil, older than any other structures in our Galaxy, and limit the universe itself in raw age. There are few, if any, young globular clusters in our Milky Way Galaxy because conditions are not ripe for more to form.
    The featured video shows what it might look like to go from the Earth to the globular cluster Terzan 5, ending with a picture of the cluster taken with the Hubble Space Telescope. This star cluster was recently found to contain not only stars formed in the early days of our Milky Way Galaxy, but also, quite surprisingly, others that formed in a separate burst of star formation about 7 billion years later.

    Have been reading about an Australian that has designed an ION drive not only simpler than NASA's but twice as powerful...needless to say NASA in interested,
    Today more news that NASA is a month away from announcing a new "EmDrive" - Using Liquid Hydrogen and Solar power this drive converts electricity into microwaves - The news was leaked onto the NASA Spaceflight forums until quickly deleted again. Part of the post says the technology is "consistantly performing"
    This drive could take astronaughts, like you and me, to the moon in 4 hours or Mars in a couple of weeks! Said to make vertical take-off and landing possible for all aircraft and even enable flying cars - Ive said for 25 years we will never have flying cars (you know how hard it is to get your civilian flying licence? There's a reason for that) - But somebody reminded me of the "driverless" technology coming out now...so I have to concede that flying cars are viable, indeed possibly preferable for most governments not wanting to spend more millions making and upgrading roads.
    This EmDrive, invented by a Roger Shawyer, could also be converted into a power generator - its coming and will change the world.

    Sounds a bit over the top for me. For one things Ion drives while efficient usually don't have a huge amount of specific impulse. Some of the performances described above would require that.

    LWD the ION drive story is separate to the Emdrive story...emdrive uses electricity and liquid hydrogen.

    Interesting. Looked up a couple of articles. Inconsistencies abound. One page said it was invented by an American another by a British scientist. Still doesn't suggest a high impulse engine.

    Yeah nothing is supposed to be officially released yet is my understanding...December seems to be the release month

    [ The Historian wrote, "This is thought to disrupt circadian rhythms, causing sleep loss and fatigue, along with other effects."]

    The residual effects of this rhythm malady, remain today. It is amazing the number of sleep disorders that I hear about on a weekly basis. They are very hard to correct and intensify with age. Sleep two hours up for one-two hrs. and repeat.

    Nice super moon today, NASA will have great shots, as will the many pro - am photographers on Mt. Balby, Kilimanjaro, etc.

    Just found this-
    "It has baffled scientists for decades - exactly what is the mystery 'third element' at the Earth's core?
    Now, a Japanese team has the answer - and says its silicon.
    Researchers have been searching to solve the mystery at the centre of our planet for decades after discovering there is something other than iron and nickel there.
    Japanese scientists believe they have established the identity of a 'missing element' within the Earth's core.
    Lead researcher Eiji Ohtani from Tohoku University told BBC News: 'We believe that silicon is a major element - about 5% [of the Earth's inner core] by weight could be silicon dissolved into the iron-nickel alloys.'
    'We measured the sound velocity of iron alloy compounds at high pressure and temperature relevant to the Earth’s core,' the researchers wrote in their presentation for the Fall Meeting of the American Geophysical Union in San Francisco."

    Hope this gets thoroughly researched. It's fascinating-
    "Roughly 7,000 years ago, Earth was briefly pelted by an influx of intense cosmic rays.
    A new analysis of ancient trees in California has revealed evidence of ‘abnormal solar activity’ in the year 5480 BC, with high amounts of carbon-14 discovered in the tree rings.
    The cause of the event remains a mystery, but researchers say it may have been the result of a change in the sun’s magnetic activity.
    The international team, led by researchers at Nagoya University, measured carbon-14 levels in the bristlecone pine forest in California.
    These trees can live for thousands of years, and hold the record of solar events that have directly affected the Earth throughout the planet’s history.
    When the sun’s activity weakens, a type of carbon called carbon-14 increases in the atmosphere.
    And, these changes can be seen in the tree rings, which absorb carbon in the air.
    ‘We measured the 14C levels in the pine sample at three different laboratories in Japan, the US, and Switzerland, to ensure the reliability of our results,’ AJ Timothy Jull of the University of Arizona says.
    ‘We found a change in 14C that was more abrupt than any found previously, except for cosmic ray events in AD 775 and AD 994, and our use of annual data rather than data for each decade allowed us to pinpoint exactly when this occurred.’"

    Would...would that indicate that the Sun controls our climate/weather?
    Gonna say- yep.
    But, but, man made global warming. ..Maybe you haven't heard algore and his insane theories (NY under water by 2000).
    Polar bears...sniff.

    Hmm....
    "New research has identified a cradle of young stars 2.4 billion light years away as the source of mysterious fast radio bursts detected on Earth.

    These bursts - which each lasted just a few milliseconds - come from dense neutron stars just 20 kilometres (12 miles) across in the constellation Auriga.

    Initially experts were baffled where these strange bursts of energy were coming from with some speculating it could be a sign of alien life trying to contact us.

    However, researchers now believe the young stars are 6,200 light years from the centre of the small galaxy called FRB 121102."

    Almost needed a defibrillator for this thread...

    "Researchers analyzing nearly 7.5 years of observations collected by NASA’s Fermi space telescope have spotted thousands of distant flares known as gamma ray bursts.
    They’ve so far been able to trace these bursts to 518 different sources in the cosmos – but, 77 sources still remain a mystery.
    While the team suspects some of these may turn out to be faraway eruptions from active galactic nuclei, they say some could represent never-before-seen phenomena."
