“Strange Evidence” Predator Resurrection

February 10, 2019

The Strange Evidence series on the Science (SCI) channel is one of the better shows currently televised on unexplained phenomena and scientific speculation. If somewhat uneven and episodic, the shows have decent production values and offer commentary and opinions by scientists as well as observers of the topics under consideration.  It’s a mixture of the far out and things that just might be possible; I like it!

With each installment comprised of several segments, the S1/Ep10 offering included camera trap footage taken in Tasmania in 2016 of an animal unfamiliar to observers that may have been a Tasmanian tiger, a species thought to have been hunted to extinction in the 1930’s with the last specimen in captivity (above) having died in 1936. Actually a marsupial, the Tas tiger was wolf-like with stripes and a long, inflexible tail. Due to the low resolution of the film taken, experts consulted could not conclusively identify the animal present, and thought it might have been a quoll, which is a smaller carnivorous mammal common to Tasmania.

So is the Tasmanian tiger still out there?  I remain skeptical, but stranger things have happened…

Autonomous, Ambulatory Robots…

February 5, 2019


Submitted for your approval is Marty, an autonomous, ambulatory robot deployed at my local supermarket to look for spills and trash. He approached me noisily from behind, beeping and flashing lights, and at first I didn’t know what was going on! Was someone pushing this thing, inside it, or remotely controlling it? — Nope, nope, and nope…but you don’t have to fear Marty.  They pasted on those ridiculous, googly eyes so as not to project a Darth Vader vibe, although that might be interesting…

Vader ‘Bot:  “I find your lack of fresh produce purchases disturbing…”

Customer:  “Alright,  just stop force-choking me,  jeez!  I’m throwing in cabbages, see?”

Vader ‘Bot:  “The General Manager will be pleased, but pray you do not require a further demonstration…”

While it will be some time before Rosie the robot from The Jetsons will be among us, the ‘bots are coming!    Marty is far from being C-3PO, but give it another ten years or so, and they could be seeking a piece of your action… 

 

High Octopi…

September 24, 2018

 

There are worse things to do to an octopus than make them high; like eating them, perhaps.  Octopuses are also normally rather antisocial creatures to the extent that they’ll fight each other to the death, much like Republicans and Democrats.

Their antisocial tendencies together with their intelligence made them alluring subjects to researchers at Johns Hopkins University, who environmentally exposed octopuses to MDMA, the psychoactive ingredient in the party drug ecstasy.  The serotonin-enhanced octopuses were then allowed access to separate chambers in one of which resided Star Wars action figures, while the other housed an undrugged male octopus.

The drugged octopuses forsook Chewbacca and a storm trooper to go all touchy-feely on the other octopus, wanting to hang out with and touch him!  Although their brains are vastly different from human, octopus behavior on the drug was similar to that of humans in terms of enhancing social behaviors.  With six more arms to hug with, it must have been quite a love-in (“His tentacles seemed to be everywhere!,” she testified).

The social enhancement behaviors were seen only in octopuses given exposure to an MDMA dosage equivalent to what a human might take; higher dosage levels resulted in the creatures lying around and staring at things, again much like humans.  And if you see a huggy octopus hanging around, please don’t send them my way.  I’ve nothing against them, but I only party with mammals… (Octopus’s Garden by The Beatles plays in the background)

Mysterious Wolf-Like Creature Identified!

June 19, 2018

 

Well, campers, we had earlier reported how a large, wolf-like creature was shot and killed by a rancher in Montana, with its identity puzzling local wildlife experts, and causing a social media tizzy around the nation.– Was this creature a dire wolf?– –  An unusual bear? – – A hybrid?- – Bigfoot?  Following DNA testing at the U.S. Fish and Wildlife Service forensic laboratory In Ashland, Oregon the results are finally in, and our mystery wolf-like creature is…(drum roll, please)...a wolf!

Hah! – – Bet you never saw that coming!  Confusion over the animal’s identity may have been caused by it’s external appearance, with the creature appearing to have short legs and big ears, but otherwise found to be a gray wolf from the northern Rocky Mountains.  According to a geneticist for the U.S. Wildlife Service, physical variations aren’t unusual for animals.  As with humans, we tend to have unrealistic expectations about animal appearances.  

So move along, folks…nothing to see here!  And there are still around 900 wolves roaming Montana…

Reptilian Mammal Fossil Found!

June 3, 2018


Evolution is perhaps coolest when we can discover examples of its transitional phases, and this little guy whose cranium was discovered nearly intact in Utah fits that bill.  Small but mighty, he weighed in at under three pounds and stood only about three inches tall.  He could probably give you a nasty bite on your ankle…

Resembling fossils previously found only in Eurasia and North Africa, the 130-million year old remains indicate that the supercontinent Pangea held together for about 15 million years, considerably longer than previously suspected, allowing for the spread of early mammals such as these and for their exploration of ecological niches.  Cifelliodon wahkarmoosuch here was fur covered and suckled their young but laid eggs, similar to the modern-day platypus.  

Described as snout-bearing and catlike with buck teeth, the critter was discovered by accident amidst a cluster of larger dinosaur bones as they were being extracted, under the foot of one of them…ouch!  Just don’t dig up your basement looking for another one…

Resurrect the Tasmanian Tiger!

May 4, 2018

   

The Tasmanian tiger or thylacine became extinct over 80 years ago when the last living specimen died at the Hobart Zoo in Washington D.C. in 1936.  But with the aide of gene editing and pickled thylacine pups, scientists may literally bring this awesome creature back to life again!

In December of 2017, scientists from the University of Melbourne sequenced the entire genome of this extinct Australian beast using thirteen thylacine joeys preserved in alcohol.  Such information could within the next decade be used to bring the unique marsupial back from the dead, with gene-editing used to bridge the gap between thylacines, which have no living relatives, and other existent species.  

Poor genetic diversity and overhunting by humans played roles in the demise of the Tasmanian tiger, which remain an iconic animal in the Australian imagination.  The government paid people to shoot Tasmanian thylacines in the 1800’s due to fears that they destroyed sheep.  Some maintain that the tassie tiger is not extinct, however, but just very good at hiding, with video footage of a bizarre hopping creature taken in North Queensland in 2015.  Wildlife experts, however, remain skeptical of the grainy, unclear, and inconclusive video…

…and wouldn’t “Pickled Thylacine Pups” be a great name for a band?!

  

Spider-Goats!

January 31, 2018


(PhysOrg.com) — Researchers from the University of Wyoming have developed a way to incorporate spiders’ silk-spinning genes into goats, allowing the researchers to harvest the silk protein from the goats’ milk for a variety of applications. For instance, due to its strength and elasticity, spider silk fiber could have several medical uses, such as for making artificial ligaments and tendons, for eye sutures, and for jaw repair. The silk could also have applications in bulletproof vests and improved car airbags.

I, for one, am both entertained and concerned with the prospect of Spider-Goats.  I mean, imagine entering one of your rooms and finding one of the buggers hanging on your wall or ceiling!  I doubt that the usual spritz of Raid spray would be enough to deter one of them.  It might, however, lead to the development of a new generation of pest controllers, Goat-Busters. — I’m claiming royalty rights on that film franchise now!  The theme song’s already playing in my head…you got goats, got yer freakin’ goats?

And we have other thorny issues to sort out, too, like cross-over problems.  Would Spider-Goat be a superhero or super villain?  Would a special issue of Spider-Man be called for featuring a knock-down, drag-out fight?  And who plays Spider-Goat in that film treatment?  Even if computer-generated, voice work is required…I’m available!

Now because the spider silk is found in the goats’ milk, could you acquire spider powers yourself if you drank it, assuming of course that you could get it down?-  – Would that be a baaad idea?  Would you then be a Spider-Goat-Person? The line is forming to the left, folks, but remember that with great power comes great responsibility…

…remember the Spider-Pig episode of The Simpsons?  We’ve all got plenty to think about now, and I think that 2018 is off to a roaring (or perhaps a bleating) start.  As Dr. Seuss might have expressed it, From there to here / From here to there / Hybrid animals are everywhere!  

At least I’ll better fit in now, someday, maybe…
