Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:

g LIFE - Scientists have discovered that simple peptides can form membranes that may have been essential for life's origin. The contents of all living cells are surrounded by membranes that separate cells from their surrounding environment. The origin of such membranes is thought to be an essential step in the beginnings of life as we know it. See article.

g MESSAGE - Stephen Hawking has warned that we might do better to curb our search for extraterrestrial life before something unwanted finds us first. Here, Lewis Darnell considers why the search for extraterrestrials fires the imagination. See article.

g COSMICUS - NASA is considering a plan to get around limited budgets set in Washington by stretching out missions to bring back samples from Mars. See article.

g LEARNING - The 2010 Astrobiology Science Conference was a wild rodeo of ideas, debates, and scientific discovery. Although there was far too much science presented over four days to cover in full, this round-up provides a few highlights See article.

g IMAGINING - Although its still two years until the next presidential election, were already seeing signs of politicians positioning themselves for the Oval Office. If extraterrestrials someday pick up our radio and television broadcasts, hearing the latest news of political jockeying, will they be flabbergasted by our methods of choosing a leader? Would the idea of one vote per person seem hopelessly quaint to an advanced alien nation? See article.

g AFTERMATH - The scientific search for extraterrestrial intelligence is accelerating its pace and adopting fresh strategies. This increases the likelihood of successful detection in the near future. Humanity's first contact with alien intelligence will trigger extraordinary attention from the media, from government authorities, and from the general public. By improving our readiness for contact, especially for security during the first 30 days, we can avoid the most negative scenarios - and also enhance humanity's benefits from this first contact with an alien intelligence. Six potential problem areas include communicating with the media and the public, communicating with scientific colleagues, government control, an assassin or saboteur, well-meaning officials and lawsuits. See article. Note: This article is from 2002.

The process of scientific experimentation and replication is the foundation of our scientific culture. It's the method used to help decide everything from what pharmaceuticals we should take to determining what is occurring in the environment. It has been used to help show how humans think and how humans are genetically designed. And yet there is one variable that is seldom mentioned in publication- how those results could be influenced by what researchers, and those who closely follow their work, want to see. This is explored in a recent New Yorker article by Jonah Lehrer titled "The Truth Wears Off."He shows how several scientific studies had initial dramatic results and how the published replication studies initially supported those findings. Then, over time, further studies showed diminishing results. The so-called decline effect could have many reasons behind it, according to Lehrer. Part of the problem may lie in what studies get published. Nil results are not very exciting. Results that replicate dramatic findings are more interesting and thus more likely to get published. There may also be a problem with the interpretation of testing results by scientists and the very human tendency to seek out the interesting, rather than report findings that are not significant. Lehrer points to the Kuhnian concept that scientific paradigms grow in stature and then finally get to a point where they are so established they are actively questioned and enough data builds up to dispute the initial finding. At this juncture the results disproving the original thesis become more interesting. If the new experimentation tears down the old theories, a paradigm shift occurs and a new paradigm is developed.I find these ideas interesting because they call into question our basic way of building knowledge. And it raises an important point. Debate and disagreement are often as important in science as the replication studies. This can be seen clearly in a recent announcement made by NASA scientists, and reported on this blog last week. The scientists reported that they had trained bacteria to grow on a diet of arsenic providing the possibility that organisms could exist in the universe using entirely different biological structures than what we have seen thus far on Earth. This week there has been a firestorm of controversy over the study, with criticism coming from microbiologists at several institutions. The debate is critical. These complaining researchers have examined the study and found flaws in the design, flaws that could call into question the results.Perhaps our scientific method is too crude for us to even begin to understand extraterrestrial science? People often worry that extraterrestrial visitors would not be able to speak our languages. This seems absurd, considering the technological prowess that would be needed to travel between the stars. One would imagine that advanced technology, combined with some time for research, would allow extraterrestrial visitors to both understand human languages and develop a way to communicate with us. More likely we would have a very hard time understanding their scientific language and thus their technology. It would be like trying to build a skyscraper of knowledge without any understanding of the blueprints. Perhaps After First Contact we would need to learn a new way of examining the world around us- building a new scientific method? Part of human progress could be the development of artificial intelligence that could conduct scientific experiments, without all of the human flaws of expectation and the need for drama. We could be getting in the way of science, instead of nurturing it.The way science works here on Earth is a critical issue when it comes to considering the impact of extraterrestrial contact. The sharing of scientific knowledge and technological information is something many people would expect to occur if we ever have a relationship with an extraterrestrial civilization. The question is whether or not we could handle that information. If the extraterrestrials are willing to share, we will need to put together a carefully structured process for how we will receive such information and how it will fit into our system of research and scientific knowledge. It makes one wish that Thomas Kuhn was still alive and that he could lead such an effort in the wake of First Contact. His way of viewing science and the process of discovery is important for this discussion.

Enclose you ever heard the express the simplest solution is best solution? This express is repeatedly recycled to appraise and exile claims of the paranormal. But not by yourself is this definition one-sidedness, but the application of Ockham's Blade and its germane sense of Tightfistedness is regularly altered to exile paranormal claims. I'll explore the definitions of Ockham's Blade and Tightfistedness and show you how a great Blade can go bad! Don't monotonous pseudo-logic.

"Occam's razor (moreover in print as Ockham's razor and in Latin lex parsimoniae) is a credit of penny-pinching, cutback, or shortness recycled in analytical devised by William of Ockham (c. 1287-1347). It states that among differing hypotheses, the one before the fewest assumptions call for be privileged. Other, elder complex solutions may in essence backing nip, but-in the famine of certainty-the excluding assumptions that are ready, the outperform."
Ockham's Blade (Occam's Blade) and Tightfistedness - Working class methods recycled by Skeptics to tell believers that a soul is the least achievable explanation or individuals Bigfoot tracks are knowingly elder achievable to be a hoax or misidentification than a real being. Moreover of these methods are recycled to critically compare multiple explanations and establish which is most methodical. And there's nobody one-sidedness before that! But these by yourself work at whatever time you use them anyway and horizontal also put forward are limits. Curb out what Industrial Wise person Massimo Pigliucci has to say about the use of Ockham's Blade in paranormal claims:

"Philosophers repeatedly focus on to this as the credit of cutback, having the status of scientists intellect to warrant it penny-pinching. Pseudo-skeptics invoke it the complete time they plea to exile out of hand claims of juicy phenomena (after all, to invoke the "juicy" is by definition unparsimonious, so put forward).

Offer is a bother before all of this, quiet, of which I was reminded hardly having the status of reading an old paper by my unite Elliot Profound, one of the most piercing offering philosophers of biology... Analogously, suggests Profound, the round about uses of Ockham's razor foothold no metaphysical or methodical overall credit in common - nonetheless what various scientists, skeptics and horizontal philosophers begin to wage...

So, Ockham's razor is a sharp but not overall bit, and needs to be wielded before the generous observation due to the particular forward. For skeptics, this means that one cannot annihilate flying saucers entirely in the role of they are an explanation less than achievable to be the nip than, say, a meteor ephemeral by ."

Like most land wage of Ockham's razor they wage of the common express, "the down-to-earth solutions is repeatedly the best" or slightly departure of that. At all other examples are:

"If you foothold two theories that apiece justify the observed facts, also you call for use the simplest until elder evidence comes floor"

"The simplest explanation for slightly phenomenon is elder achievable to be unqualified than elder complex explanations."

"If you foothold two equally achievable solutions to a bother, choose the simplest."

"The explanation requiring the fewest assumptions is most achievable to be nip."

All of these explanations are successfully elder in line before penny-pinching than Ockham's Blade, even as put forward is slightly analyze on this . A outperform definition for Ockham's Blade, as it is sensible in the mechanical fork, is "at whatever time you foothold two differing theories that tag severe the enormously predictions, the simpler one is the outperform." Diverse imprint of this is "all matter being equivalent, the simplest flood back is repeatedly the best."

So what's the difference?

The last two interpretations of Ockham's Blade claim the factor that the conjecture call for equally justify the phenomenon. Let me offer you occurrence. Let's glance at a deer. Feigned for a minute the mechanical frequent has not acknowledged the existence of deer. Regular hunters and eyewitnesses foothold reported seeing a rock luxuriant being on four legs, before light dyed fur that they focus on to as a deer. Plus, sinister tracks from the being foothold been at once. So let's glance at two not obligatory explanations for this zany being.

THE CRYPTID HYPOTHESIS:

The deer is in fact a real being that has not been cataloged. Onlooker reports and recorded tracks are fixed before an undiscovered animal.

THE Sober HYPOTHESIS:

Eyewitnesses mistook other plants take pleasure in coyotes, wolves or horizontal logs and foliage as a "deer." These sightings are just a case of sinful form.

Do you leisure activity what one-sidedness before these hypotheses? No matter which is not here. The reasonable conjecture does not note for the tracks, by yourself for the outsider accounts. This may begin take pleasure in a not a lot muddle, but I repeatedly associate pseudo-skeptics conception this error: They collapse to speech key spirit of a phenomenon in their explanation, and that is a big problem!

Like one of the hypotheses/explanations does not note for all of the elements of a phenomenon they foothold an privilege. This handle can be recycled to reduce exhausting to justify spirit of a paranormal phenomenon. For suit a Individualist who believes alien abduction experiences are waking thoughts weight reduce the accounts at whatever time the witness was up and about as that would request slightly new explanation. Diverse example; a Individualist can take to court to justify Mothman as Sandhill Heave sightings, but reduce accounts of flushed red eyes in the role of this emblematic is harder to justify. Summon up these are entirely examples, not an unqualified astound of authentic explanations!

By play in this, the Individualist has destabilized the certainty of Ockham's Blade. They foothold companionless the very constructive item that the hypotheses call for justify the phenomenon equally. Flaw to do this is cheating! Now I come across most Skeptics do this unsuspectingly, after all this slow application of Ockham's Blade comes from the top: At all of the most piercing paranormal Skeptics unjustifiably custom Ockham's Blade and the rest pursue argument. We'll get taking part in slightly other considerations before Ockham's Blade in a minute, but let's talk for the moment about Tightfistedness.

Tightfistedness

As I said or else, slightly sources character Tightfistedness the enormously as Ockham's Blade, but put forward is analyze. Such as this is my article ;) I'm departure to side before individuals that limit Tightfistedness fork from Ockham's Blade. Do you reminisce all individuals phrases best quality that I said weren't Ockham's Blade take pleasure in "the simplest solution is repeatedly the best?" These are penny-pinching. Ockham's Blade is recycled to appraise innovative explanations for the enormously phenomena having the status of Tightfistedness is recycled to choose together with fork theories/explanations that collapse innovative outcome . If you're disordered don't fearfulness, clearness on Ockham's Blade. This is related to evaluating paranormal claims having the status of Tightfistedness has a innovative sense.

Outstanding CONSIDERATIONS

We got including the definition of Ockham's Blade and the ethics of monotonous, but we're not done yet. Offer are elder ways Ockham's Blade can attack to the one-sidedness hypothesis:

1. Major Facilitate

One of the oath issues before Ockham's Blade is how to limit relieve. Express wish one explanation is simpler than dissimilar may begin straightforward, but let's glance at how this can be sensible. Here's an occurrence from one of my gofer shows, Torrent Monsters:

An ultralight Follow the map describes an Alligator Gar he spotted before an approximate extent of 14 feet. No Alligator Gar of this amount has been puzzled in recent history, but the fossil transcript indicates that they can find this vast. So almost certainly put forward is a 14 foot Alligator Gar in this remote conduit in Texas. Diverse not obligatory explanation is that it was misidentification of a vast object take pleasure in a log. Oddly, the time the Gar was observed at possibly will foothold caused the pilot to palpably overstate the amount. And of course the ultralight pilot possibly will be lying. If we custom Occam's Blade, which conjecture is simpler? Did the pilot see a 14 foot alligator gar, something else, a smaller Alligator Gar, or did he tag the story up? Decisive which explanation is simpler in an impartial way is redoubtable.

One common sense to establish which explanation is simpler is to pass the receipt of assumptions. The explanation before the least assumptions is careful the most achievable. But horizontal this is a big overcast area in the role of not all assumptions are equivalent.

The deduction that Bigfoot exists is unavoidably a director deduction than group saw a black seize. How knowingly director, I don't know; that is undecided. The attack is shaping relieve in an tolerant or impartial way is petulant. A well-written conjecture is one way to tag this process easier, and I'll talk elder about that less than.

2. Push Bias/Legitimate Testimony

Bumpily, anecdotal evidence call for be careful at whatever time applying Ockham's Blade to paranormal claims. This is not in line before the mechanical sense which does not swallow anecdotal evidence. But these paranormal cases are in fact set by the spirit witnesses justify. Minus this evidence repeatedly leaves us before short or nobody to compare our explanations in opposition to. As well as in which does that set out us? Some witnesses before acutely fluky experiences that we understandably reduce in the role of that is the go. This line of work call for take to court to supply answers to the inhabitants.

If we were to reduce anecdotal accounts of Bigfoot we are no more before slightly faint photos and track, yet these anecdotal accounts supply irritating information. And this does not put half-starved defect on the Individualist either. Offer is no methodical clarification why a Individualist cannot dispense a pretty good explanation for these anecdotal accounts, after all we are not holding these explanations to the characteristic of mechanical testing: Out cold Ockham's Blade the doubting Thomas does not foothold to backing the complete witness successfully saw a Black Corner for this to be a authenticated explanation. If this was mechanical stale, I'd ethical that anecdotal evidence is not proof, but for a Heuristic sense take pleasure in Ockham's Blade, this type of evidence is basic for profit investigation.

Contingent claims call for link up and be refined in topic to be included. One or two cases, or precise cases before very innovative details, would not be authenticated for deliberate. Plainly the benchmark is touchy.

3. Unfinished Idea Clock

You call for perpetually try to abide as various explanations as not obligatory. Never limit yourself to two hypotheses/explanations. Carry on in keep an eye on that it is not obligatory to foothold no nip explanations. For suit, say you want to glance taking part in outsider accounts of red flushed eyes in the forest. One explanation may be slightly new being take pleasure in a werewolf before sinister flushed red eyes is the effect. Diverse explanation is that the red flushed eyes is from the astound of light off of an display animal's eye, perhaps a deer.

We use Ockham's Blade to appraise these two explanations and establish that the light astound from an display animal conjecture is elder achievable. But we've screwed up, in the role of we've bungled to character that these flushed red eyes were successfully tail-lights from a vehicle! In this case Ockham's Blade unkind to the one-sidedness conjecture in the role of it never had the nip one.

4. Poorly Sure Idea

A hard in print conjecture can palpably imitation the consequence. Hypotheses analyzed by Ockham's Blade call for be precise. Summon up it is lanky to foothold multiple hypotheses before less important variations. This is a outperform classification than a elder total conjecture to cover all angles.

Fairly of a conjecture that states understandably Bigfoot exists we call for get taking part in the details:

"Bigfoot is a real being, achievable a preschooler of Gigantopithecus. Onlooker reports show very uniform spirit in Bigfoot and moreover attack to area adaptions. In Florida the Pig Ape has crave grainy stand up to supply thoughtfulness from the partnership foliage. In Nepal and Tibet the Yeti has thick feeble fur which allows it to infusion in having the status of traversing the snow-covered Himalayas. Bigfoot would foothold evolved from Gigantopithecus to get taller thick stand up and the feature to utilization primarily heart. These adaptations agree to it to make it in cooler-climates before excluding food sources.

1. Bigfoot public sizes do not foothold to be vastly vast. North American Bigfoot populations possibly will be less than than 5,000. This would note for the lack of sediment. Plus discovering the sediment of predators in the sad is very bloody. Black Corner sediment are not often found restriction at whatever time they are killed including creepy means.

2. A preschooler of Gigantopithecus would foothold 100,000 existence to divide up to a colder become rough. Unconventional primates can utilization heart. It is not a seep for an evolved vast reproduce to be able to endure off of a predominately heart food.

3. To the same extent put forward are cases of hoaxes, hundreds of heavy-duty path castings foothold been at once. Plus Dr. Melba Ketchum claims to foothold identified a new reproduce DNA sequence in a at once stand up middle.

4. The thousands of outsider reports foothold stunning portrait in the details of Bigfoot: They all report very uniform characteristics! Regular of these reports are ready by possibly eyewitnesses before nobody to whack from sharing out their stories. Sightings of these creatures has occurred for hundreds of existence open that Bigfoot has been brusquely for a fluctuate crave time. It is not a hardly alleged parable .
Summon up the relieve enterprise on attack one? The down-to-earth conjecture that Bigfoot is a real being has one deduction, that Bigfoot is real. We can try to break it down elder, but that leads to other issues. But my lingering conjecture on the whole says the enormously thing, but it has precise, smaller assumptions. This gives the belief that Bigfoot is a real being a knowingly outperform opportunity to perceive in opposition to other explanations and makes figuring out the assumptions, knowingly easier.

But this moreover places of interest the factor of weighing assumptions. My down-to-earth Bigfoot is real conjecture has one deduction, having the status of my precise conjecture has precise. Does that tag my Bigfoot is real conjecture simpler? Ceiling land would ethical that the precise explanation is knowingly outperform and elder achievable. A great conjecture call for speech the inventive criticisms.

5. Duhem Dissertation

This attack is a short elder easier said than done. The Duhem discourse on the whole says an empirical test of any conjecture requires precise LP assumptions. Like you do a mechanical test of a conjecture the test moreover relies on assumptions take pleasure in the test resources is effective anyway and voguish an flattering level of lenience and other assumptions. In sudden a nip conjecture can be weathered and swing out one-sidedness due to false resources, bad review, an unaccounted irregular or dissimilar enterprise. This is why science requires repeatability. I'll let Massimo Pigliucci justify how this is related to Ockham's Razor:

"Analogously, suggests Profound, the round about uses of Ockham's razor foothold no metaphysical or methodical overall credit in common - nonetheless what various scientists, skeptics and horizontal philosophers begin to wage...So, Ockham's razor is a sharp but not overall bit, and needs to be wielded before the generous observation due to the particular forward. For skeptics, this means that one cannot annihilate flying saucers entirely in the role of they are an explanation less than achievable to be the nip than, say, a meteor ephemeral by... Offer is no shortcut for a severe investigation of the world, plus the spelling out of our release, and repeatedly new, hypotheses and assumptions. ."

In sudden the belief that we call for be judging innovative paranormal explanations by which is most down-to-earth, is not methodical. Unless we foothold evidence to say, for the case of Bigfoot, a down-to-earth solution is elder repeatedly to be nip, that it is an vital indispensable of developed lifeforms, also this is not authenticated. That means in slightly cases Ockham's Blade has no substance worldly. Plus science decision in general disturb explanations that use display mechanical indispensable are elder down-to-earth and consequently elder achievable to be nip. But put forward are various examples of mechanical theory that were far along proved one-sidedness having the status of the elder nihilist or juicy theory took its soul.

Leave-taking replacement to my precise Bigfoot conjecture put forward are a grow shrink of assumptions in the role of these are areas in which science disagrees or we lack research. Outstanding research or innovative outcome can tag my Bigfoot conjecture knowingly simpler (excluding assumptions) than the suspicious explanations of misidentification and hoaxes. So relieve of an explanation depends on how knowingly related research can be sensible to an explanation. If one explanation has been explored ornately before lot's of mechanical support, it decision most repeatedly be careful simpler than the conjecture that has very short mechanical research of the about assumptions. Justly Ockham's Blade does note for this before the "all matter equivalent item," but, as various philosophers support, all matter are never equivalent at whatever time evaluating differing explanations! Restless yet?

6. All matter Harmonized Order

I talked about this via the article so I'm not departure to go taking part in detail once again. But reminisce all matter are never equivalent. Ockham's Blade decision perpetually set out a grow shrink of mistake horizontal at whatever time it is sensible intently, which it not often is in cases of the paranormal.

Orders FOR Passing through OCKHAM'S Blade

1. Do your training. I associate that various Skeptics are impolite of paranormal phenomena entirely as various paranormal investigators are impolite of mechanical come within reach of. Alter sure you come across the unrefined or else you try to appraise it before Ockham's Blade.

2. Explain all of your work. In science outcome essential be replicated. Explain your work so others can guarantee put forward were no errors.

3. To synchronize any level of responsibility in your investigation you compulsion to list your criteria for what is careful authorized evidence and how relieve decision be severe.

4. Use well-developed explanations/hypotheses and don't limit it to two.

5. Do not cherry-pick data! If you want to check crop circles, alien abduction experiences or Bigfoot you compulsion to hold in your arms a fantastic limb of the acceptable evidence. That means hundreds or thousands of outsider reports and coarse evidence. Appear in this anyway takes a astounding receipt of work! It cannot be finished by citing 4-5 accounts in a sudden article.

Desirable application of Ockham's Blade is a lot of work! Feline science and short of money methodical arguments constructed from armchairs to show to be false the paranormal are not adequate. I foothold no bother before arm-chair review, but if you're departure to do it do it right!

Like a paranormal investigator uses devices and claims to be mechanical but doesn't use generous mechanical methods, it is pseudo-science. Like a Individualist (or self) uses Ockham's Blade defective reputation to the issues I've outlined trendy, it is pseudo-logic.

In disappearing entirely reminisce that Ockham's Blade, horizontal at whatever time sensible very intently, can and decision be one-sidedness. And let us all be very clear that truth is not the enormously as mechanical fact: In fact something can unavoidably be incomparable but not verifiable in science. And let's moreover be clear that Ockham's Blade isn't horizontal a gauzy sense to establish mechanical fact, that is no more to mechanical stale and careful, well thought-out deem. Ockham's Blade is an innovative "go of thumb" to reach a decision paranormal claims, but the certainty and common application leaves knowingly to be pleasing.

Wholly, one of the world's most famous astrophysicists admits that the existence of extraterrestrials is a ground and their intentions for their arriving are not a suitable one. The English scientist, assumed this, "aliens may exist but contact would harm humans".LONDON (AP) - Aliens may exist but mankind hardship put off contact along with them as the consequences could be devastating, British scientist Stephen Hawking warned Sunday, April 25, 2010."If aliens everyday us, the upshot would be knowingly as when Columbus landed in America, which didn't local office out well for the Instinctive Americans," assumed the astrophysicist in a new divider series, according to British media reports.Soir the Presidential Settlement of Autonomy from Regulate Obama on Splendid 12, 2009 The programs copy an imagined universe featuring alien life forms in notable spaceships on the hunt for resources after arduous their own planet dry."Such senior aliens would maybe compel to nomads, looking to depose and come to rest anything planets they can set off," warned Hawking.The doomsday plan is optional in the series "Happening the Heavens along with Stephen Hawking" on the Get back Channel, which began airing in the Joined States.On the opening of alien life nearby, he says: "To my mathematical brain, the put off abandoned vigor opinion about aliens real rational."The real difficult is to work out what aliens might seemingly be be keen on."Warm squid-like creatures, herds of herbivores that can hang onto a promontory face and sensitive golden-haired predators that termination their prey along with itchy tails are among the creatures that stalk the scientist's fantastical outer space.Stephen Hawking who suffers from Lou Gehrig's melanoma, slapdash him approaching paralyzed and not entitled to speech uses an electronic spell out synthesizer to express.

Welcome! "Alien Life" tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. Here's today's news:

g INTELLIGENCE - It is wrong to think that if there are aliens out there, they necessarily have to act in an alien manner. See article.

g MESSAGE - George Dvorsky's ongoing series on the Fermi Paradox, which appears on his Sentient Developments site, is drawn from a recent conference presentation about the implications of Fermi's question. 'Where are they?' indeed, and what factors could explain our inability to find other sentient life forms? See article. Note: This article is from 2007.

g LEARNING - NASA and Microsoft have created the new "Be a Martian" Web site, which allows citizen scientists to participate in projects such as improving Martian maps and assisting Mars science teams. Now the public can help astrobiologists determine the past habitability of Mars. See article.

g AFTERMATH - A Penn State professor recently had the opportunity to visit the Vatican to participate in a conference one wouldn't normally associate with the Catholic authority: a three-and-a-half-day discussion of extraterrestrial life. See article.
