Since 1980, paleontologists have suggested that a terrible meteorite impact millions of years ago radically altered the Earth's climate and killed off the dinosaur population. Now a study led by David Jolley of Aberdeen University proposes that there was a second major impact a few thousand years after the first:

In the current study, scientists examined the "pollen and spores" of fossil plants in the layers of mud that infilled the crater. They found that immediately after the impact, ferns quickly colonised the devastated landscape.

Ferns have an amazing ability to bounce back after catastrophe. Layers full of fern spores - dubbed "fern spikes" - are considered to be a good "markers" of past impact events.

However, there was an unexpected discovery in store for the scientists.

They located a second "fern spike" in a layer one metre above the first, suggesting another later impact event.

Etsy seller ArtAkimbo created a sculpture that looks like a tentacle entering the room through a porthole. It's made from wood, styrofoam, newsprint, and sawdust. At the link, you can see pictures of what it would look like in a well-furnished office or bedroom.

On the left, you can see the destruction of Praxis, the moon of the Klingon homeworld. It blows up in the beginning of Star Trek VI: The Undiscovered Country. On the right, you can see the end Death Star from the 1997 re-release Star Wars: A New Hope. One astronomer, Phil Plait, argues that the rings appearing in both explosions show a poor understanding of physics, but the one appearing in Star Wars is somewhat more plausible.

In his 2002 book Bad Astronomy: Misconceptions And Misuses Revealed, From Astrology To The Moon Landing 'Hoax', Plait casts doubt on the verisimilitude of (Lucasfilm effects house) Industrial Light And Magic's seminal CGI effect depicting the explosion of the Klingon moon Praxis in Undiscovered Country. Since explosions in space tend toward spherical shape unless impeded, Plait concludes that the blast pattern resulting from the explosion of the Klingon mining operation has no credible reason to resolve into a ring form, even if everyone thinks the effect is far cooler here than in 1997's revised New Hope.

Conversely, the surface integrity of the Death Star hull is interrupted by a perfect ring in the form of the gargantuan maintenance trench which encircles it, meaning that at this point of interrupted stress, a growing explosion would find the least resistance. This makes the highly criticised 'ring effect' far more plausible in New Hope [V.2.0] than its predecessor in Star Trek VI.

This time-lapse video by YouTube user szyzyg shows asteroids in our solar system as they have been discovered since 1980:

Notice now the pattern of discovery follows the Earth around its orbit, most discoveries are made in the region directly opposite the Sun. You'll also notice some clusters of discoveries on the line between Earth and Jupiter, these are the result of surveys looking for Jovian moons. Similar clusters of discoveries can be tied to the other outer planets, but those are not visible in this video.

As the video moves into the mid 1990's we see much higher discovery rates as automated sky scanning systems come online. Most of the surveys are imaging the sky directly opposite the sun and you'll see a region of high discovery rates aligned in this manner.

At the beginning of 2010 a new discovery pattern becomes evident, with discovery zones in a line perpendicular to the Sun-Earth vector. These new observations are the result of the WISE (Widefield Infrared Survey Explorer) which is a space mission that's tasked with imaging the entire sky in infrared wavelengths.

Astronomers have so far found about half a million minor planets in our solar system.

Perhaps, like flight attendant Steven Slater, you need to escape from a bad job or social situation. Slater had an inflatable emergency slide handy, but until now, few of us had this option. Pictured above is an advertisement for a fake product called Slip Quit -- a portable slide for those desperate situations.

This video shows a man stripping of his clothes and jumping into a hay baler. A few seconds later, the baler spits him out in the middle of a bale of hay.

This is either footage of an idiot, a viral advertising stunt, or both. What do you think?

Content warning: as I said, the guy gets naked. The video doesn't show anything -- at least not up close. But, you know: fat, middle-aged naked man warning.

Remember the woman who found a cat on a sidewalk, stroked it, and then tossed it in a garbage bin? One cat recently retaliated against an innocent woman, as you can see from the above security camera footage.

Michael Wiles of Melbourne, Australia was riding his motorcycle when he found a grill by the side of the road. He decided to take it home and so placed it over his body and started riding. Police investigated the incident after the above photo of him began circulating the Internet:

Paul McClure, his defence lawyer, said Mr Wiles's excuse was "lack of thought processes" at the time and poverty.

"It turned out the barbecue was a dud and did not work, and that's probably why it was at the side of the road," Mr McClure said.

"This is stupid behaviour and nobody should do it."

A new road near Pontypridd, UK obstructs the travels of dormice -- a mouse species that lives in the area. So to accommodate the dormice, the local government built wire mesh bridges that the rodents can use over the road:

The bridges consist of wire mesh tubes suspended between trees and tall poles.[...]

When completed, the tubes will be solid mesh to stop the dormice falling out.

As dormice live in trees as opposed to on the ground, their routes have to stretch between trees instead of along underpasses used by, for example, hedgehogs and badgers.

The View-Master, a classic American toy since 1939, uses stereoscopy to present 3D images. Hacker Consortium user tuttle thought that he could do the same thing with modern technology, and so replaced the internal components of one with tiny digital screens:

Long gone are the days of light shining through celluloid images on a disk… Long gone! Why this little feller here has Two, count them, 2 Colby 1.5 inch digital key chain picture frames lined up with each lens to create a digital stereoscope. Wait there’s more don’t go. What more you ask? Well this little device actually comes pretty damn close to doing stereoscope really well. It even surprised me!

At the link, you can view more images of the mod. tuttle promises to provide instructions at Instructables soon.

Otis the cat is overweight, so his human put him on an elliptical trainer. The cat was fascinated with it. As Otis explored the machine, he hopped from step to step, operating it.
