Longest Eclipse!

July 22, 2009

eclipse— If you missed today’s solar eclipse that was visible across much of Asia, tough luck; there won’t be a longer one until 2132!  In parts of Asia, today’s eclipse lasted as long as 6 minutes and 39 seconds, the longest since July 11th, 1991; it will not be equaled again in this century.

A solar eclipse is a celestial event historically met with a mixture of awe, excitement, and fear; in Hindu mythology, an eclipse is caused when a dragon-demon swallows the sun.   More than one soon-to-be-boiled missionary in hack writing has been saved by conjuring up knowledge of an impending eclipse to intimidate a primitive native population…

The Last Dinosaur?

June 25, 2009

sauropod–A previous post here has looked at Mokele-mbembe, but now MonsterQuest has done a feature as well.  Going into the West African jungle in search of a sauropod-like creature with a long neck and tail and a small head, Mokele-mbembe is a territorial, amphibious creature known to attack humans.  It is active at night, browsing on leaves.

The first written accounts of the creature came from odd claw marks found in the Congo in 1776.  Pygmies are familiar with the beast, but believe that they will surely die if they report it, which puts a bit of a damper on things.

An underwater sonar survey by MonsterQuest found crocodiles, snakes, and “unusual profiles,” some of which were likely tree branches…and the dark and murky waters of the African rivers weren’t conducive to sightings.  The remote location of the investigation and the politically dangerous nature of the area also hampered the search…so once again, MonsterQuest came up empty.

Our imagination or not, humanity needs great mysteries.  This is yet another one of them…

The Starchild Skull

June 22, 2009

starchild— Featured on UFO Hunters, the Starchild Skull is an unusually elongated and flat skull further distinguished by extremely shallow eye sockets and a total lack of front sinuses, morphology which cannot be accounted for by any known combination of deformities.  The skull appears similar to what one might anticipate from the “Greys,” the classic alien stereotype. UFO afficionados speculate that the skull may be that of a Grey alien/human hybrid.

The Starchild Skull was found in a tunnel in Mexico in 1930, and clinically speaking is that of a young male child.  Carbon-14 dating places the skull at about 900 years old, with mitochondrial DNA identifiable as coming from a human mother; useful lengths of nuclear DNA have not yet been recovered.

The skull is comprised of real bone, although the bone is half as thick, weighs half as much, and is substantially more durable than normal human bone.  There are also microscopic fibers and a reddish residue inside the bone that defies explanation.

Hydrocephaly has been ruled out as a cause of the abnormalities, although this does not rule out an as of yet unidentified illness causing the malformations…the truth is out there!

Killer Jellyfish Invasion!

May 28, 2009

box jellyfish– – Or so was how MonsterQuest described this episode…but somehow, a jellyfish attack lacks the “shock and awe” factor of say, a shark attack.  Still, it is a matter to be reckoned with, as the sting of a box jellyfish can kill in three minutes!

The box jellyfish featured is an apex predator feeding on shrimp and small fish; it kills swiftly with a potent cardiac venom that is said by victims to burn like acid when delivered by the creature’s tentacles.  Some experts feel that the box jellyfish may even target their prey, hunting and chasing fish.  The implication is that such jellyfish may possess a form of intelligence.  As the veteran of a college invertebrate zoology course, I feel that invertebrates deserve more attention and greater respect than they usually are accorded.

The global jellyfish population is rising, possibly due to global warming, which we ignore at our peril.  Jellyfish invasions, while they sound more gross than dire, have hit Spain, Ireland, and Japan, among other locations.  Deaths have resulted in some cases.

MonsterQuest searched Australian waters, and came up with a four foot Australian spotted jellyfish.  The creatures cannot be produced on demand, being subject to water salinity, temperatures, and storms.  I don’t have nightmares about them…but wouldn’t care to meet one of the big boys, either!

Missing Link?

May 26, 2009

Ida– – The History Channel aired a most intriguing presentation on the evening of May 25th called, The Link. It concerned possibly the oldest and most complete human ancestor,  a 47 million year old fossil primate revealing an over 95% complete skeleton and even a soft body outline!

Discovered in Germany in the 1980’s, locked up for 25 years, and then secretly but intensely studied by a team for two years before revelation, this is the fossil of a small female arboreal primate less than a year old who lived in Germany in the trees of what was then an ancient rain forest.  Named “Ida” after the daughter of Dr. Hurum who acquired the fossil, the fossil may be that of a transitional species, a “lemur-monkey” which captures a crucial stage in evolution, incorporating features from both the human and non-human evolutionary line.- – The fossil is visually stunning and conceptually mind-boggling!–This puppy could be big!

If this fossil is a fraud as some are already saying, it’s an extremely good one.  The fossil incorporates a deformed right wrist which was likely broken and badly-healed. – -Heck, the remnants of Ida’s last meal are even represented in the stomach area!  The fossil also shows a shape adaptation in the Talus bone of the foot towards assumption of an upright posture.

If a true transitional fossil or “missing link,” this discovery will likely dominate textbooks for 100 years; this could be an awesome find!   As also expressed on the show, for those uncomfortable with the notion of evolution, “Ida’s existence will be a problem for many.”

The Hobbit Man…

May 11, 2009

hobbit man– – If you like your early human species small, you may want to consider Homo  floresiensis, a tiny species of extinct humans nicknamed “hobbits” that grew to an adult height of no more than three feet and existed and lived for tens of thousands of years in Indonesia before dying out about 17,000 years ago.

H. floresiensis possessed unusual anatomical characteristics as a function of their complete isolation on a remote island home such as long toes, flat feet,  and a small head. The species walked easily on two legs, but likely found it difficult to run at speed.  First unearthed in 2004 in a cave on the island of Flores, they were initially thought to be suffering from a pathological condition such as microcephaly, but are now felt to be a true human species which evolved as the outcome of living on a remote island for so long…

Invertebrate Intelligence…

May 5, 2009

frieda–It is perhaps bias that generally causes us to think that only mammalian species display intelligence and evidence of learned behavior.   Certain invertebrates also display intelligence…

…for example, an octopus named Frieda at the Munich Zoo has learned to open jars with her tentacles, joining a small but elite group of mollusks that have also mastered this task.  Frieda can even discern between empty jars and those which contain her favorite snacks, such as shrimp, clams, and crabs. To accomplish this task, Frieda positions her entire body over the lid of a wide-mouthed jar and grasps the sides with her tentacles.  With a full-body twist, she wrenches the lid off!

Who knows, we may someday may see invertebrates like Early and Rusty on Squidbillies…will they drive cars, buy guns, and run for the school board?

Depression-Creativity Link?

April 7, 2009

depressed–Depression strikes writers, artists, and musicians up to ten times as often as the general population, a tendency often attributed to the creative spark.  But according to one study (Paul Verhaegher, Syraccuse U.), it’s the artist’s propensity for rumination that often leads to the blues, not creativity itself.

Self-reflection seems to breed both depression and creative behavior…

Blue Moon…

March 13, 2009

moonNASA has unveiled plans to return a man to the moon by 2018; that’s sooo far away!  The last lunar landing took place in 1972 (Apollo 17), long before many of you reading were a gleam in your father’s eye.

Things seemed to be moving ahead more quickly in the early days of the space program, when there was even optimistic talk of a mission to Mars by the the late 20th century.

The future’s just not getting here fast enough!  And I want my flying car as seen in The Jetsons…they’re long overdue!

The Resurgence of Science

March 10, 2009

obama-brings-back-science–Praise God, the sciences have made a comeback in their acceptance by government!  I am thrilled that President Obama is encouraging more open scientific discussion and research without political interference.  As Obama well expressed it, “Our government has forced what I believe is a false choice between sound science and moral values.”  Obama has signed documents changing U.S. science policy and removing what some researchers have said were shackles on their work.

Obama elaborated, “It is about ensuring that scientific data is never distorted or concealed to serve a political agenda–and that we make scientific decisions based on facts, not ideology.

The most immediate effect of this will be to allow federally funded researchers to use hundreds of new embryonic stem cell lines for promising research in hopes of creating better treatments and even cures for conditions ranging from diabetes to Parkinsons Disease to paralysis.  While some don’t like the fact, we are a religiously pluralistic society, and spiritual and scientific belief need not be mutually exclusive.  The ethical imperative to relieve suffering and promote healing is well served by this decision and change in policy.

I’m beginning to feel like we are starting to live in the 21st century…Hallelujah!
