Everything You Wanted to Know About Dinosaur Sex Read
How did these dinosaurs—bristling with spikes and plates—go about making more dinosaurs without skewering each other?
Stegosaurus has become an icon of the mystery surrounding dinosaur sex. Dinosaurs must have mated, but just how they did so has puzzled paleontologists for more than 100 years. Lacking much hard evidence, scientists have come up with all kinds of speculations: In his 1906 paper describing Tyrannosaurus rex, for instance, paleontologist Henry Fairfield Osborn proposed that male tyrant dinosaurs used their minuscule arms for “grasping during copulation.” Others forwarded similar notions about the function of the thumb-spikes on Iguanodon hands. These ideas eventually fell out of favor—perhaps due to embarrassment as much as anything else—but the question remained. How can we study the sex lives of animals that have been dead for millions upon millions of years?

Jerusalem UFO video debunked
Here’s the original video that’s been circulating with more here.
t’s pretty cool, but an obvious hoax. Imagine you’re standing late at night videotaping the scene with a friend because it’s so pretty. Out of nowhere a bright light comes down out of the sky, hovers over one of the most famous temples on the planet, then flashes brilliantly and shoots straight up at fantastic speed.
Would you just stand there like a lump without showing any reaction at all, like the guy in the video?
Also, it seems a little weird that such an incredibly bright object could hang over this heavily visited site, even in the middle of the night, and there were no reports of any eyewitnesses. Just one video that turns up, and a few days later a couple more. Seriously?
And now this video has been conclusively shown to be faked.

Walking improves your memory
Exercise training increases the size of our hippocampus and improves memory. They divided 120 sedentary healthy adults in their mid-60s into two groups. From a summary:
One group walked around a track three times a week, building up to 40 minutes at a stretch; the other did a variety of less aerobic exercises, including yoga and resistance training with bands. After a year, brain scans showed that among the walkers, the hippocampus had increased in volume by about 2 percent on average; in the others, it had declined by about 1.4 percent. Such a decline is normal in older adults.

Magic meets Mysticism in Tanzania
Swaziland police have said they will keep a registry of every albino in the country to help protect them from witch doctors who wish to use their body parts for rituals, the Christian Science Monitor reports. The move comes after the killing of an 11-year-old albino girl, which many fear is the first in the expansion of a deadly superstition already prevalent in eastern Africa.
Some are willing to pay tens of thousands of dollars for the body parts of albinos—which they believe will cure diseases or bring political power—on the black market. “Swaziland, which has been identified as a destination, source, and transit point for human trafficking, which also occurs for trade in body parts, is clearly no longer exempt of this type of crime, where young albinos are targeted” says an abuse group.
“Witchcraft today in the West might be a relic of history and filed as a bygone chapter of the 16th century, but still today throughout Africa – the belief in witchcraft and the brutal effects of those beliefs are being felt strongly – some say more strongly than ever.”
In August of this year British magician Drummond Money-Coutts set out to investigate the extent to which witchcraft and witch doctors still hold a grip over the people of Tanzania in East Africa where, according to the BBC, belief rates in witchcraft are at 93% – the highest in the world.
Reports of killings, said to be as many as 3 a day or roughly 1000 a year, appear to be reliable however the number doesn’t appear to be declining. “The demographics of the victims are varied”, says Drummond, “but largely focused on those most defenceless – the very young and the very old. It’s astonishing to think that today in a world that has easy access to information there are still pockets of the world falling prey to the wild and savage claims of such people.” (more…)
New, Much Smaller Cousin To T-Rex Unveiled
Having only one claw on each forelimb and standing about the size of a parrot, a tiny distant cousin of Tyrannosaurus rex was discovered in China and named Linhenykus monodactylus, after the city of Linhe in Inner Mongolia where the fossilized remains were found.
The remains of the dinosaur representing a sub-branch of the theropods, which include a partial skeleton, bones of the vertebrae, forelimb, hind limbs, and a partial pelvis, were removed from sediments between 84 and 75 million years old in what archaeologists have dubbed: The Upper Cretaceous Wulansuhai Formation.
Besides T-Rex, therapods also include the Velociraptor, from which scientists believe the bird kingdom, as we know it today evolved. Details surrounding the process were published in the Proceedings of the National Academy of Sciences.
This small cousin of the terrifying T-Rex did have unusual claws but its presence would hardly have raised a hair of fright on any creature crossing its path.
Astrologers angered by stars
“Professor Brian Cox and Dara O’Briain have unleashed the wrath of Britain’s astrologers with their comments about the ancient art on BBC2′s “Stargazing Live” show, with the result that the Astrological Association of Great Britain have started a petition they plan to send to the BBC.
The section of the program that caused the fuss has been described in truly harrowing terms by ‘respected astrologer’ Angela Cornish, in an e-mail that was published by the SkyScript blog:
“If you didn’t happen to see it, there were two presenters, Professor Brian Cox and Dara O’Briain. All was going well until they got to a part where they had models of the planets in our solar system on a table and Dara was explaining that all of the planets orbit at different speeds and distances away from the Sun. He said only the earth orbits the Sun in 365 days and returns to its own place, showing that horoscopes are nonsense. He then went on to add “Let’s get this straight once and for all, Astrology is rubbish” The other presenter, Brian Cox, then agreed and said “in the interests of balance on the BBC, yes astrology is nonsense.”
Shocking stuff, I think you’ll agree.
This is not the first time that Brian Cox has waded into the astrology controversy that has raged in science for literally almost none of the last couple of centuries. The hackles of Britain’s astrologers were raised last year, when Cox took a moment during his Wonders of the Solar System series to explain to the public that “astrology is a load of rubbish,” a statement which pretty much echoes the scientific consensus on the matter, which says that, “astrology is a load of rubbish.” It’s a position that was first reached by Islamic scholars at least 650 years ago, and has been studiously ignored by such great minds as Jonathan Cainer ever since.
Since then, TV’s most clean-shaven male Professor has become a bit of a lightning rod for astrologically-guided criticism, and the Astrological Association of Great Britain’s new petition names him personally:
The Association will be requesting that the BBC make a public apology and a statement that they do not support the personal views of Professor Brian Cox or Dara O’Briains on the subject of astrology. We also request that the BBC will commit to making a fair and balanced representation of astrology when aired in the future.
On the second sentence at least I think we can all agree. I’d love to see the BBC give a fair and balanced representation of astrology. In fact sod it, let’s extend that to all newspapers as well.
Such a representation would depict astrology as a pseudoscience with no real basis in evidence that was already being ridiculed in the Dark Ages, and note that after thousands of years astrologers still can’t produce statistically meaningful results.”

Thomas Thwaites: How I built a toaster — from scratch
“It takes an entire civilization to build a toaster. Designer Thomas Thwaites found out the hard way, by attempting to build one from scratch: mining ore for steel, deriving plastic from oil … it’s frankly amazing he got as far as he got. A parable of our interconnected society, for designers and consumers alike.”

The secret to commanding lightning
“Mouths agape, a crowd stare at two men with lightning bolts firing from their heads and hands. I am at the Big Day Out, a music festival in Sydney, Australia, and touring alongside the likes of Iggy Pop and MIA are the Lords of Lightning.
The display is indeed stunning to watch. “It was like two wizards fighting,” says Toby, a Sydney hipster who quickly scampers back to the festival’s pounding music. Little did he wonder: how came these mere humans to create and command lightning?
The secret to the Lords’ power is Tesla Coils. The ones they use are two metres wide, on which they stand while thick blue bolts fly around them. First developed in 1891 by Nicola Tesla, a Tesla Coil is in fact two coils – one sitting inside the other. When an alternating current builds up in the smaller coil it creates a magnetic field that induces a current in the larger one.
In the show, one primary coil is wound around two secondary coils which service the two towers. This ensures both towers vibrate at the same frequency. Voltage in the larger coil can build up into millions of volts once the coils vibrate at precisely the same frequency. “That’s what causes the huge voltage rises that you see in the way of lightning,” says Carlos Van Camp, the creator of Lords of Lightning.
To ramp the voltage further, he winds the coils so the towers are pumped with opposing charges. “So, at maximum, one tower reaches two million volts and the other reaches negative two million,” says Van Camp. The massive voltage generated by the Tesla Coil rips surrounding air molecules into charged ions, allowing a current to flow through the air. This is similar to what it is believed happens in nature. While there is some debate, it’s believed that lightning is caused by the sudden release of charge from thunderclouds, which get electrically riled up by collisions between ice particles. Since most of the charge is negative, the ground becomes positive. Once the electric charge becomes large enough to ionise the air, a current will flow as a lightning bolt.
So, how can Van Camp stand atop these massively charged structures and walk away unscathed? He wears a conductive suit made of very small metal links connected together which protects him from the voltage. Electricity runs through the suit rather than through his body, and discharges out of his hands and head.
“If the suit has all the connections in place then you don’t feel anything,” says Van Camp. But, when there are loose connections electrical charges can move off track. When this happens, Van Camp says he can “feel little tingles to thumping shocks inside the suit”. But perhaps it is this danger that entices crowds.”
