Smoking = Stupidity

Effects of smoking
I don’t know how to sugar coat this in some politically-correct, sensitive, caring way that doesn’t overtly offend anyone, but if you haven’t already figured this out by now, here it is: smoking is stupid. Really stupid.

Even worse, smoking makes you even more stupid while you do it:

Researchers tested the IQs of more than 20,000 healthy men between the ages of 18 and 21 who were either serving in the Israeli military or who had recently completed their service. Twenty-eight percent of the men in the sample smoked, while 3 percent were former smokers and 68 percent had never smoked. The average IQ of the smokers was 94, compared with 101 among the non-smokers. Men who smoked more than a pack of cigarettes a day had an average IQ of 90. Although a normal IQ falls between 84 and 116, the difference observed in the study is still considered significant.

And if you’re a heavy smoker and heavy drinker, your IQ plummets to the point you’re going to find yourself watching Fox ‘News’ and thinking it was time to give Sarah Palin another chance. Or even Stephen Harper, if you’re binge drinking.*

Evolutionary Dead-Ends

Some people seem genetically inclined – perhaps I should write doomed? – to believe in nonsense: believe in conspiracy theories, in myths, legends, superstitions and supernatural, in magic, in pseudoscience and pseudomedicine. Nothing – no amount of fact, truth, education, reason or contrary evidence will change their minds. The harder you try to correct them, the more firmly they believe.

Watch, if you can, this painfully dim woman trying to dismiss paleontology and evolution as she blunders through Chicago’s Field Museum of Natural History’s exhibit on the evolving Earth and comments on the displays. It’s a tough video to view for anyone with an IQ bigger than your shoe size. Within seconds you’ll be wincing and asking yourself “Can anyone really be this stupid or it is a joke?”

[youtube https://www.youtube.com/watch?v=32mxZxv3dYM#t=746]

Yes, they can be that stupid. I couldn’t make it all the way through in one sitting. I had to stop and clear my head. Shake it, drink wine. Who is this woman, you ask? According to Patheos, she is a public nuisance who is also a

…self-described “homeschooling, Tea Partying, conservative mother”

Okay, I have a low opinion of all of those categories even without the head-shaking, face-palm-encouraging video.

Dragons? She really believes dragons were dinosaurs and humans walked around the planet with them? Cave paintings of dinosaurs? (This has been long debunked by better minds than mine). She believes in a global evolutionist conspiracy theory trying to hide this stuff?

Maybe this critique will be easier to follow and less painful to watch:

[youtube https://www.youtube.com/watch?v=oNGAtFDm7OY]

or this one:

[youtube https://www.youtube.com/watch?v=y9v0RjhAEUU]

or even this condensed version.

One even has to have some sympathy for the museum staff who suffer such fools among their visitors. It almost makes me wish there were a higher power who could ensure such wingnuts don’t reproduce. Just a prod with that magic finger and *zap* they’re out of the evolutionary game. Damn, too late for this one…

Robocalls from Real Robots

“mmm…buzzz…. click…. This is your friendly….buzzz…. automated calling device…click…hummmm… reminding you that….mmmm….buzzz…..click… there are only three days left to…. zzzzz…. take advantage of the Black Friday sales at…. mmmm…. buzzzz….. your…. zzzz… Collingwood…..insert box store name…. mmmm…buzzz…. click….thank you…”

Solenoid RobotsWell, maybe robotic telemarketers won’t sound like the solenoid robots on Roger Ramjet, but within the decade, most telemarketers will be machines, not humans. So when they interrupt your dinner to tell you you’ve won a free cruise, shouting at them and slamming down the phone won’t hurt their feelings at all. Mmmmm….buzz…. click…

Of course, a lot of this work is already automated, but according to a recent report called Fast Forward 2030: The Future of Work and the Workplace, half of today’s current workforce will be replaced by robots or some form of automation in 2025, telemarketers being at the top of the list for outplacement by machines. Repeat: half of the current workforce.

(Now, I have to admit I was puzzled as to why CBRE, an international real estate firm, would commission such a report. But regardless of the source, the report is fascinating, if perhaps a bit Pollyanna-ish in its conclusions about this upcoming revolution in the workplace…. especially when it quietly suggests on page nine another recession is coming… )*

Reporting on the report, the New Zealand Herald noted,

…experts now believe that almost 50 per cent of occupations existing today will be completely redundant by 2025 as artificial intelligence continues to transform businesses… A 2014 report by Pew Research found 52 per cent of experts in artificial and robotics were optimistic about the future and believed there would still be enough jobs in the next few decades… The optimists envisioned “a future in which robots and digital agents do not displace more jobs than they create,” according to Aaron Smith, the report’s co-author.

Rather to the contrary, Stephen Hawking is reported in a BBC story warning that,

The development of full artificial intelligence could spell the end of the human race. “It would take off on its own, and re-design itself at an ever increasing rate.

Tesla’s CEO Elon Musk warned that artificial intelligence potentially could be “more dangerous than nukes. Yes, yes, we all immediately think of Terminator’s Skynet AI and the robots.

[youtube=https://www.youtube.com/watch?v=CN__WyMfEKw]

But when it comes to telemarketers, I think I’d rather have Skynet. And Bell Canada’s customer “service” reps? Forget the robots and just replace them all with cement roadblocks… that’s what they are, after all… mmmm…. buzzzz…. click….

The Pinnacle of Homeopathic Stupidity

Toilet medicine“Have Homeopaths Reached Peak Stupid?” asks the headline on Quackometer.net. It’s hard to imagine anyone getting dumber than a belief in homeopathy (aka The One Quackery to Rule Them All), but apparently there are higher levels within their madness that homeopaths continue to scale. This, however, looks like their Everest of stupidity.

The story in question is about the plan by homeopaths to “heal the oceans” last week. Admirable goal, but it’s the implementation that will make you laugh so hard you’ll snort your morning tea right out of your nose. You have been warned. I speak from experience.

Here’s how they plan to heal the oceans: flush their pseudo-medicines down the toilet. Yes, I agree that’s ALWAYS the best thing to do with homeopathic nonsense. But according to a UK homeopathic wingnut, this is supposed to fix the oceans.

Okay, you’re wondering how a vial of homeopathic magic potion – which is simply water – can heal the pollution of the massive oceans? Well, so is everyone. It can’t. But that didn’t stop them. Wait, it gets more amusing.

Comets, Aliens and Conspiracy Wingnuts

Image from RosettaThe European Space Agency has accomplished one of the greatest engineering and scientific achievements in human history this past week. Not only did it get a space vehicle into orbit around a comet travelling at more than 55,000 km/hr (34,000 mph), it landed a probe on the very rough surface of that comet. Outstanding, brilliant, superb… the superlatives fail me when trying to describe this event.

The Rosetta spacecraft chased Comet 67P/Churyumov-Gerasimenko for ten years (since March, 2004) travelling almost four billion miles (6.4 b km) to rendezvous with the small chunk of icy rock, currently about 510 million kilometres away from Earth.

The rubber-duck-shaped comet is about 2.5 miles across at its widest: a tiny body compared to even a  mid-sized asteroid, and it’s blacker than coal. Even finding it in the emptiness of space is a remarkable feat, let alone establishing an orbit around it and sending back stunning photographs. But if that isn’t incredible enough, yesterday Rosetta deployed Philae, a tiny lander, to settle on the rapidly rotating comet, to take photos and conduct experiments – a feat so remarkable it defies description.

This is the sort of scientific effort we should be celebrating worldwide, shouting about it from the rooftops. But apparently the wingnut crowd has a different view. They think it’s an alien spacecraft the ESA is secretly monitoring (with the nefarious military and secret government agencies, of course).

It took almost no time for the conspiracy theorists “identified” UFOs, towers and alien monuments, faces, radio towers and even a pyramid in the photos broadcast from the comet. The internet is polluted with this kind of nonsense.

Crazy Cats and Brain Parasites

Brain parasitesIt reads like a script for a scary movie: an alien parasite invading our brains, taking control of our minds, changing our behaviour silently, secretly; making us do what it wants. And it’s happening now, in homes across Canada and the USA. Alien puppet masters over-running the nation, one household at a time.

But it’s not fiction, although my scenario is a trifle exaggerated.

They’re not some right-wing aliens from outer space subverting our natural goodness and compassion; not some cyber-bullying bloggers dripping political poison into the gullible minds of their readers.They are microscopic, found worldwide, on land and in water – including saltwater – and may be infecting people you know this very minute. Or even you. They’re Toxoplasma gondii; an amoebic parasite pretty much capable of infecting any warm-blooded creature.

Where they breed, however, is in your cat, and are then excreted in their feces:

Although T. gondii can infect, be transmitted by, and asexually reproduce within humans and virtually all other warm-blooded animals, the parasite can sexually reproduce only within the intestines of members of the cat family (felids). Felids are therefore defined as the definitive hosts of T. gondii, with all other hosts defined as intermediate hosts.

As an owner of four cats and having had cats most of my life, this is troubling. But not entirely new. Back in 2012, in an article in The Atlantic, titled, “How Your Cat Is Making You Crazy,” Kathleen MacAuliffe wrote:

The parasite, which is excreted by cats in their feces, is called Toxoplasma gondii (T. gondii or Toxo for short) and is the microbe that causes toxoplasmosis—the reason pregnant women are told to avoid cats’ litter boxes. Since the 1920s, doctors have recognized that a woman who becomes infected during pregnancy can transmit the disease to the fetus, in some cases resulting in severe brain damage or death. T. gondii is also a major threat to people with weakened immunity: in the early days of the AIDS epidemic, before good antiretroviral drugs were developed, it was to blame for the dementia that afflicted many patients at the disease’s end stage. Healthy children and adults, however, usually experience nothing worse than brief flu-like symptoms before quickly fighting off the protozoan, which thereafter lies dormant inside brain cells—or at least that’s the standard medical wisdom.

But if Flegr is right, the “latent” parasite may be quietly tweaking the connections between our neurons, changing our response to frightening situations, our trust in others, how outgoing we are, and even our preference for certain scents. And that’s not all. He also believes that the organism contributes to car crashes, suicides, and mental disorders such as schizophrenia. When you add up all the different ways it can harm us, says Flegr, “Toxoplasma might even kill as many people as malaria, or at least a million people a year.”

To be fair to cats, the parasites live in soil, too, so they’re hard to avoid. Plus they’re also found in undercooked meat. You like your steak blue? Or bloody rare? You may be inviting this parasite into your brain. And also if you drink contaminated water or eat uncooked or undercooked shellfish. Those raw oysters you love? Parasite havens. Yum.

Timothy Leary Was Right. Maybe.

This is your brain on drugs
This is your brain on drugs. Or rather, the right-hand image is your brain on psilocybin. The other side is your brain on a non-psychedelic drug. Researchers recently discovered some amazing facts about how our brains work on some chemicals. And some psychedelic drugs prove to have pretty amazing effects. But don’t try this at home… stick to building toy rockets and drones for your science experiments…

Apparently Timothy Leary was right: psychedelic drugs change the way users think. For a long time, possibly forever. In his pioneering work, The Psychedelic Experience (1964), Leary wrote

A psychedelic experience is a journey to new realms of consciousness. The scope and content of the experience is limitless, but its characteristic features are the transcendence of verbal concepts, of space-time dimensions, and of the ego or identity. Such experiences of enlarged consciousness can occur in a variety of ways: sensory deprivation, yoga exercises, disciplined meditation, religious or aesthetic ecstasies, or spontaneously. Most recently they have become available to anyone through the ingestion of psychedelic drugs such as LSD, psilocybin, mescaline, DMT, etc. Of course, the drug does not produce the transcendent experience. It merely acts as a chemical key — it opens the mind, frees the nervous system of its ordinary patterns and structures.

He also said in a 1966 CBS documentary about his work,

We always have urged people: Don’t take LSD unless you are very well prepared, unless you are specifically prepared to go out of your mind. Don’t take it unless you have someone that’s very experienced with you to guide you through it. And don’t take it unless you are ready to have your perspective on yourself and your life radically changed, because you’re gonna be a different person, and you should be ready to face this possibility.

A story in Wired Magazine about this new research described the image above:

A representation of that is seen in the image above. Each circle depicts relationships between networks—the dots and colors correspond not to brain regions, but to especially connection-rich networks—with normal-state brains at left, and psilocybin-influenced brains at right…
In mathematical terms, said Petri (study co-author Giovanni Petri, a mathematician at Italy’s Institute for Scientific Interchange), normal brains have a well-ordered correlation state. There’s not much cross-linking between networks. That changes after the psilocybin dose. Suddenly the networks are cross-linking like crazy, but not in random ways. New types of order emerge…
Petri notes that the network depiction above is still a simplified abstraction, with the analysis mapped onto a circular, two-dimensional scaffold. A truer way of visualizing it, he said, would be in three dimensions, with connections between networks forming a sponge-like topography.

Debunking Homeopathy. Again.

Homeopathy. It’s absoHomeopathic cartoonlute bunk. But you already know that. All those forms of ‘magic medicine* are bunk, of course, but homeopathy has a special place reserved for it in the kingdom of codswallop.

Codswallop is dangerous to the mind, and often to your wallet, but homeopathy compounds that by being dangerous to your health, too, even fatal, as Penelope Dingle discovered. Yes, homeopathy can kill you, if you take it’s fake cures instead of actual medicine or treatment.**

But, you ask, if a placebo works (in some cases), what’s wrong with it? As Joel Gottsegen wrote in the Stanford Daily last week, it’s the pseudoscience baggage that attends its use that is equally dangerous:

Helping people with chronic pain via the placebo effect is nice, but there are many ways to achieve this effect that create less collateral damage. Giving someone a sugar pill is relatively simple. Creating an enormous ideological framework that clouds people’s judgements about mainstream medicine is not. The biggest problem with practitioners of alternative medicine is that they often deny the soundness of scientific studies as a measurement of the efficacy of a treatment. This is a dangerous sentiment. If Deepak Chopra were to discover a new form of medical treatment that helped sick people, it should be possible to test that the treatment is actually working. By denying the validity of the scientific method, alternative healers free themselves from any kind of accountability.

The Atlantic Magazine quoted Steven Salzberg, a prominent biology researcher at the University of Maryland at College Park, saying homeopathy is a…

…cleverly marketed, dangerous quackery. These clinics throw together a little homeopathy, a little meditation, a little voodoo, and then they add in a little accepted medicine and call it integrative medicine, so there’s less criticism. There’s only one type of medicine, and that’s medicine whose treatments have been proven to work. When something works, it’s not all that hard to prove it. These people have been trying to prove their alternative treatments work for years, and they can’t do it. But they won’t admit it and move on. Of course they won’t. They’re making too much money on it.

I got back onto this old horse of an argument recently when a Facebook poster responded to my posts urging residents to get a flu vaccine by saying, “If you care for your health, take a homeopathic alternative with no added toxins.” No added anything, really, since homeopathic “remedies” are simply placebos and what you get in those little pills is a little sugar and nothing else.

Taking nothing does just that: nothing. If you care about your health – and that of others – you’ve already had your flu shot. Homeopathic “remedies” will not prevent the flu from spreading or infecting anyone. In fact they’re actually helping spread disease.

In short: homeopathy is bunk, and dangerous, unhealthy bunk at that. It’s taken off these days because of the internet-driven conspiracy-theory gullibility that pervades our culture. Terms like “Big Pharma” are used to scare people who are already deeply suspicious of government, corporations, developers, Liberals, contrails, medicine, vaccinations and science. Ooh, scary…

Words, Your Brain and Sex

Naked readingOne of the reasons I’m a dedicated librocubularist* can be found in a story on IFL Science that is headlined, “Learning New Words Activates The Same Brain Regions As Sex And Drugs.” It opens:

While it doesn’t get much better than sex and drugs for many out there, new research has found that simply learning a new word can spark up the same reward circuits in the brain that are activated during pleasurable activities such as these. No wonder there are so many bookworms and scrabble addicts out there.

So nothing like a good, brisk read through the Compact English to get in the mood, eh? Get all purfled from the effort of learning new words. While you groak your snoutfair mate and suggest she festinate her reading while she tells you to be testudineous while she deliciates her words…

The actual article this story draws from doesn’t exactly say that learning new words is the same as sex or drugs. What it says is that learning them lights up the regions of the brain that kicks into play when it wants to reward you. At least it works on people who were being studied under MRIs, not necessary those in libraries or bookstores. Don’t go ecstasiated over it, yet.

It does the same thing for gambling, although I have to admit for this unrepentant mumpsimus, my own reward-centre connection for learning kicks a much more powerful punch than that for gambling. It’s a burden I bajulate well, though.

The Ebola Panic

Jenny McCarthyEbola has gripped the imagination of North American media and been spun into a terrifying spectre looming like a horseman of the apocalypse over us. So widespread has it become that Jenny McCarthy, one of the top wingnuts of quackery and pseudomedicine, and poster girl for the pro-measles-pro-mumps parents, felt compelled to pipe up with her own “cure,” should it spread to the USA:

Lemon juice.

Yep. Wonder how the scientists missed that one. A quick trip to the grocery store and you’re immune. Safe easy and natural!

Well, okay, she didn’t really say that. It was from a story posted on The Daily Currant, a satirical website and shared on social media as if it was a real story. Not even McCarthy is that moronic. I hope (it’s hard to tell…).

The same site also had stories titled, Sarah Palin: ‘Can Obama Stop The Ebola Zombies?’ and “Justin Bieber Hospitalized With Ebola” and Ann Coulter: ‘Give Ebola to Migrant Children’.

That doesn’t mean the wingnut crowd McCarthy belongs to hasn’t been busy spinning its nonsense. There has been the usual pile of steaming codswallop coming from the conspiracists about ebola as with chemtrails, morgellons and the New World Order. It’s been called a hoax on the loony tune sites. And on one a government population control device:

A buzzword around the internet lately, describes that the US government has either bought or created patents of a virus “called” ebola (not necessarily the same as the original from 1976), and is being used for either population control or as a bio-weapon for use on foreign powers that the government is at war with.

I know, I know: who comes up with this irresponsible, paranoid madness? (Apparently the scare/hoax/conspiracies are fueled by a profit motive… at least in part.)

The point is that ebola – a few years ago barely known outside the virus hunters of the CDC – is now a household word and a hot topic on social media. It scares people (and clearly befuddles the wingnuts). So much so that Ann Coulter, harridan for the Tea Party actually did chime in on it (although she lacks any knowledge about medicine or science to justify her comments), albeit to use it as a platform to launch another anti-Obama-pro-white-racist attack:

Conservative pundit Ann Coulter on Wednesday joined the bandwagon of right-wing critics questioning why President Barack Obama hasn’t instituted a travel ban for the African countries battling the Ebola epidemic — perhaps with the goal of preventing those who are infected from getting “free medical treatment” here in the U.S

Calling Coulter a pundit is obviously sarcasm; Salon more fittingly calls her a “professional troll.”

“A” Personalities: A Theory

GoodreadsWhen someone tells me he is an “A-type” personality, I cannot help but think of the title of Aaron James’ bestselling book: Assholes *A Theory (Anchor Books, New York, 2014). After all, what else would the “A” stand for when someone boasts to the audience he is an alpha male as if the rest of the room was full of less-worthy betas?

Self aggrandizement is not limited, of course, to assholes, but they certainly occupy centre stage (at least in their own mind). Not always the best place to be, considering that, medically speaking, A-types are more prone to heart disease than B-types.

As Wikipedia tells us, Type A personalities are,

“…ambitious, rigidly organized, highly status-conscious, sensitive, impatient, take on more than they can handle, want other people to get to the point, anxious, proactive, and concerned with time management… often high-achieving “workaholics” who multi-task, push themselves with deadlines, and hate both delays and ambivalence.
…Type A behavior is expressed in three major symptoms: (1) free-floating hostility, which can be triggered by even minor incidents; (2) time urgency and impatience, which causes irritation and exasperation usually described as being “short-fused”; and (3) a competitive drive, which causes stress and an achievement-driven mentality.

Not entirely flattering a description, is it? Rigid, status-conscious, ambivalent, impatient, short-fused, irritable, hostile, competitive… not the sort of person you want at a council table where cooperation, consensus and respect make for good governance. A-types at the table generally are seen by others as assholes. Hence the mnemonic association with the book. One wonders why anyone would boast of this.

Aaron James writes of a dichotomy between cooperative people and these A-types:

Even the “bright-line” rules of cooperation will have exceptions and cooperative people often put a certain amount of work into discerning both the spirit of the law and what is finally acceptable in a particular case. They thus seek clarification, check assumptions, ask permission or at least take a measure of care in good faith. The asshole, by contrast sees little need for the work of mutual restraint aimed at benefit for all involved. According to his generalized sense of entitlement, it is only natural that the various advantages of social life should flow his way.

(For the sake of politeness and civility, I am inclined to find another name for assholes. I cannot merely call them jerks, because James differentiates between assholes and mere jerks. Twits, idiots, dweebs, boors, shmucks, cads, jackanapes… these names fail to capture the essence of those truly despicable people whom James describes. I think I will have to simply refer to them as “a*holes” so as not to entirely dilute the impact.)

A-type, A*holes, pretty much the same thing, at least as far as I can fathom. Of course, I’m not a psychologist and I’m sure there are subtle shades of difference I fail to discern.

B-type personalities, on the other hand, Wikipedia says, work well together:

…generally live at a lower stress level and typically work steadily, enjoying achievement but not becoming stressed when they do not achieve. They may be creative and enjoy exploring ideas and concepts. They are often reflective…

Sounds like someone much easier to get along with in a group dynamic like the council table: unstressed, creative, exploratory, reflective. People who will contribute rather than control, will think rather than merely act. People you can work with and respect. people who use “we”  when describing accomplishments and work as a team. People unlikely to be described in James’ book.

A-types, however, will find themselves in it.

Earth’s magnetic field could flip within a human lifetime

An intriguing possibility was reported on Science Daily this morning:

Earth’s last magnetic reversal took place 786,000 years ago and happened very quickly, in less than 100 years — roughly a human lifetime. The rapid flip, much faster than the thousands of years most geologists thought, comes as new measurements show the planet’s magnetic field is weakening 10 times faster than normal and could drop to zero in a few thousand years.

Why would this matter? The article continues:

And since Earth’s magnetic field protects life from energetic particles from the sun and cosmic rays, both of which can cause genetic mutations, a weakening or temporary loss of the field before a permanent reversal could increase cancer rates. The danger to life would be even greater if flips were preceded by long periods of unstable magnetic behavior.

When will this happen? That’s the big question behind the headline. Soon, warn geologists. But their “soon” in geological time doesn’t mean the same as “your breakfast will arrive soon” in a restaurant. It seems overdue for a flip, but no one is sure when that might happen. A 2002 story in The Guardian warned that it was imminent – in geological terms:

“Some experts have stuck their necks out to predict that we can expect the next reversal some time in the next 2,000 years.”

I think we can have that cup of tea while we wait. It may not happen in our lifetimes. But, the article has that shock effect nonetheless:

The Earth could be about to turn upside down. The planet’s magnetic field is showing signs of wanting to make a gigantic somersault, so that magnetic north heads towards Antarctica, and magnetic south goes north. Compasses will point the wrong way, and migrating birds, fish and turtles are going to be very confused.
Just when this will happen, how long it will take and what the consequences will be, is difficult to fathom. What is not in doubt, though, is that it will happen. About every half a million years or so, the Earth’s magnetic field flips upside down.

And that’s the worry: every half-a-million years is a lot less time than the 786,000 years since the last flip-over. This summer, Scientific American warned it could happen sooner rather than later:

Earth’s magnetic field, which protects the planet from huge blasts of deadly solar radiation, has been weakening over the past six months, according to data collected by a European Space Agency (ESA) satellite array called Swarm.
The biggest weak spots in the magnetic field — which extends 370,000 miles (600,000 kilometers) above the planet’s surface — have sprung up over the Western Hemisphere, while the field has strengthened over areas like the southern Indian Ocean, according to the magnetometers onboard the Swarm satellites — three separate satellites floating in tandem.
The scientists who conducted the study are still unsure why the magnetic field is weakening, but one likely reason is that Earth’s magnetic poles are getting ready to flip, said Rune Floberghagen, the ESA’s Swarm mission manager. In fact, the data suggest magnetic north is moving toward Siberia.

So we wait, unable to do anything about it. Have another cuppa, if you must. Yes, you have time.

The Utility Animal

In the July/August edition of Pets Magazine (the Cat Care issue) there are two articles that caused me concern. One is “The Loyalty and Bravery of a Cat” (p.28), the other is “Quick-Thinking Cat Saves the Day.” (p.26). The latter is a pet profile from the Purina Hall of Fame that honours pets for “extraordinary actions.” The former is about a YouTube video showing a family cat attacking a dog that had itself attacked the family’s four-year-old son.

The acts themselves and the cats involved are extraordinary and deserving of praise as individual animals. But the idea that cats in general need to be propped up as utility animals, that in order to have intrinsic value they need to perform some service for humans, bothers me deeply.

It also annoys me that cat lovers feel the need to be defensive about cats and find ways to make them seem more like dogs. They are separate species with very different social (pack) cultures and cannot be expected to behave like one another.

All animals evolved to fulfill their own purpose. Some have become domesticated through their interactions with humans; a few are even companion animals we call pets. Dogs and cats top that small list. And a small percentage of those perform acts that are of use or beneficial to humans.

Valuing an animal on the basis of its utility is to devalue the life of that animal. Animals do not exist to serve human needs. Yes, they can be trained to perform tasks, but that isn’t their purpose.

Cats have value simply by being cats. All life has its own inherent value and we cannot measure that value against its usefulness to our lives. Not should not – cannot. There is no appropriate measuring stick.

Any attempt only promotes subjective value judgments over other species. It’s akin to measuring the distance to a neighbouring planet by the number of bicycle lengths between us. Irrelevant.

Value your pet, value all life, for what it is. Not what use, not what advantage and not what profit you can gain from it. And I am happy to share my home with my pets for the sake of their companionship alone.

Gut instincts

Ars TechnicaA story on Science Daily says research suggests our so-called “free will” may be less free than we ever imagined. We may, instead, be meat puppets ruled by the desires and cravings of the smallest symbiotes we carry: our gut bacteria.

The story opens:

It sounds like science fiction, but it seems that bacteria within us — which outnumber our own cells about 100-fold — may very well be affecting both our cravings and moods to get us to eat what they want, and often are driving us toward obesity… researchers from UC San Francisco, Arizona State University and University of New Mexico concluded from a review of the recent scientific literature that microbes influence human eating behavior and dietary choices to favor consumption of the particular nutrients they grow best on, rather than simply passively living off whatever nutrients we choose to send their way… the authors believe this diverse community of microbes, collectively known as the gut microbiome, may influence our decisions by releasing signaling molecules into our gut. Because the gut is linked to the immune system, the endocrine system and the nervous system, those signals could influence our physiologic and behavioral responses.

Actually this is not really surprising. It has long been known that human evolution has been affected by both viral and bacterial presence, as well as having our own DNA encoded with bits from them. And recently it was discovered bacteria can encode DNA from other animals – even dead ones – into their own.

The discovery of the recombinant DNA process should have alerted everyone to the wider possibility that there may be biological analogues already. After all, it only makes sense that in any symbiotic relationship, there must be some way for all parties to communicate with each other for mutual survival. The gut is a competitive environment with numerous species, so they also need a mechanism for cooperation and communication in ways that also help keep the host alive.

Most life on the planet has some form of symbiotic relationship and many are mutually beneficial like that with our gut flora, although there are also parasitic relationships as well.

The First Dark Age

End of the Bronze AgeThe causes of the first “Dark Age” have long been the topic of debate among historians and archeologists. Many ideas and theories have been put forward; none have found universal agreement. It’s commonly referred to in scholarly circles as “The Catastrophe.

Nor do they explain why the empire of Egypt and Assyria, both on the periphery of the larger area affected, seem to have escaped relatively intact from the collapse – although Egypt’s might and influence came out of the period severely diminished.
