A species of assassin bug, Stenolemus bituberus, sneaks onto spiders’ webs and pretends to be prey, then captures and eats the spider when it comes to investigate. It was noted that on occasion the ploy of the assassin bug failed and it ended up being a meal for the spider regardless.

“The assassin bug slowly approaches the spider on its web, using its forelegs to pluck the silk threads in a manner that simulates the vibrations of a fly struggling after being caught. Wignall studied the behavior of the bugs, and found that the response of the spider to the predator was the same as its response to when a vinegar fly or aphid was caught in the web.”

That cute little star that you’ve pointed out to your son/daughter/neice/ward you’re training to fight crime? It could be an insanely badass wormhole big enough to fit a human or spaceship.

So the next time you’re telling the story of the sky make sure not to skip the part where we could all be sucked in a sweet wormhole and battle beings from another dimension. And stuff.

Wikileaks founder Julian Assange spoke with The Guardian including this awesome tidbit:

Many weirdos email us about UFOs or how they discovered that they were the anti-christ whilst talking with their ex-wife at a garden party over a pot-plant. However, as yet they have not satisfied two of our publishing rules.
1) that the documents not be self-authored;
2) that they be original.
However, it is worth noting that in yet-to-be-published parts of the cablegate archive there are indeed references to UFOs.

So causing an international kerfuffle revealing covert forces for freedom and democracy in the regions most in need of it, putting in danger deep cover assets and confirming Moammar Gadhafi as a cold pimp is totally within bounds, but UFO cable is a little too dicey to reveal?

This news report on a Jamaican Ghost was sent to us today. Our question to you the reader, was this set up from the start or did the news crew genuinely stumble upon an afflicted family? Thanks to Nathan for sending this in.

Researchers from the Multisensory Perception and Action Group at the Max Planck Institute for Biological Cybernetics in Tübingen, Germany have provided evidence that if you ever become lost in the desert you are more than likely going to cross your own path. Using GPS tracking, the scientists dropped people off in the Sahara and forests in Germany and monitored their movements. As long as the subjects had visible cues as to their direction from the sun or the moon, they managed to walk a relatively straight line. However, as soon as they had no indicators, they immediately started walking in circles.

“The results from these experiments show that even though people may be convinced that they are walking in a straight line, their perception is not always reliable. Additional, more cognitive, strategies are necessary to really walk in a straight line. People need to use reliable cues for walking direction in their environment, for example a tower or mountain in the distance, or the position of the sun.”

Scientific American takes a good long look at the crossroads between moss and animal: the bryozoan. To celebrate, we are reposting one of the most disgusting bryozoan videos we’ve ever posted. Hooray!

But still, they did release this totally ominous press advisory:

NASA Sets News Conference on Astrobiology Discovery; Science Journal Has Embargoed Details Until 2 p.m. EST On Dec. 2

WASHINGTON — NASA will hold a news conference at 2 p.m. EST on Thursday, Dec. 2, to discuss an astrobiology finding that will impact the search for evidence of extraterrestrial life. Astrobiology is the study of the origin, evolution, distribution and future of life in the universe.

I, for one, welcome our new overlords!

Scientists have studied a centuries worth of comet data and come to the conclusion that at least 20 percent of visible comets were kicked out of the Oort Cloud by a Jupiter-sized object lurking at the solar system’s outer edge. Eighty percent of objects pushed out of the Oort cloud could be explained by the gravity of the galaxy, but the remaining comets would have required an object 1.4 times the mass of Jupiter to kick them out.

In 1999, Matese and colleague Daniel Whitmire suggested the sun has a hidden companion that boots icy bodies from the Oort Cloud, a spherical haze of comets at the solar system’s fringes, into the inner solar system where we can see them.

In a new analysis of observations dating back to 1898, Matese and Whitmire confirm their original idea: About 20 percent of the comets visible from Earth were sent by a dark, distant planet.

U.S. and Filipino scientists have announced the discovery of a new species Teuthidodrilus samae, which they immediately named “squidworm.” It is a flat, eyeless, free-swimming worm with up to ten squid-like appendages. It also has twenty five or more pairs of translucent fins arranged on its sides for swimming. The creatures were found between 6,650 and 9,550 feet below the surface of the ocean in the Celebes Sea between Indonesia and The Philippines.

That having been noted, the squidworm differs dramatically from all known worms in that it is a polychaete — a type of bristly annelid that is generally found in marine environments — and seems to be a missing link between benthic polychaetes living on the seafloor and pelagic ones dwelling much further up.

The Cassini space probe recently scanned the atmosphere of Saturn’s second largest moon, Rhea, and discovered that it is comprised of 70% oxygen and 30% carbon dioxide.  In the past the Hubble Space Telescope has detected thin oxygen layers on Europa and Ganymede around Jupiter, but this is the first time oxygen has been seen directly in the atmosphere of another world. Scientists are not holding out hope for life on Rhea at this point though.

“All evidence from Cassini indicates Rhea is too cold and devoid of liquid water necessary for life as we know it,” Teolis told them.

Are you planning on camping in the wilds of Norway soon? Are you worried that trolls are going to attack your camp and try and feast on your flesh while you sleep? Then perhaps you should build your very own Trolldetektor v.1.0b. The Trolldetektor is an Arduino-based project that uses an accelerometer, LEDs, and some nifty code to let you detect when and which type of troll is descending on your camp.  The source code currently detects Rimtusse, Raglefant, and Skogstroll troll types based on the impact and frequency of their approaching footsteps. The code also notes:

“PS: This code may be rewritten to detect earthquakes, but trolls are worse…. alot worse….”
