And of course, Brains...
Will fermentation work the same in weightlessness? What happens to carbonation when there's no buoyancy to bring the bubbles to the top? Can space beer form a proper head? Scientists who study the physics of gas-liquid mixtures would love to know!Only 2?
Two separate space shuttle experiments tackled these questions....
The European Brain Council (EBC) is recommending a boost in research efforts following the publication of a report stating that 127 million Europeans suffer from brain disorders,How else to explain George Galloway?
I sometimes wonder about how large numbers of voters can support him.All of the faked charges constantly repeated by the Loony Left concerning George Bush have been proven correct about their own current
A provincial politician and political hack. Someone who's a millionaire, who's been proven to be at the heart of all sorts of shady oil deals, and a man who insists that deployment of his country's armed forces in Iraq is purely a matter for his own country's voters to decide, and to hell with anyone else, especially the Iraqis.
A man who uses his personal wealth and the full force of the law to crush any opposition to what he says or stands for.
A man who until recently supported the most foul of dictators, and whose words about "Democracy" ring hollow.
Here in the twenty-first century we like to view ourselves as ambulatory brains, plugged into meat-puppets that lug our precious grey matter from place to place. We tend to think of that grey matter as transcendently complex, and we think of it as being the bit that makes us us.Perhaps the definition of "intelligent life" might have to include all animals with spindle cells, and thus the capacity for love, hate, and so on.
But brains aren’t that complex, Kurzweil says. Already, we’re starting to unravel their mysteries.
"We seem to have found one area of the brain closely associated with higher-level emotions, the spindle cells, deeply embedded in the brain. There are tens of thousands of them, spanning the whole brain (maybe eighty thousand in total), which is an incredibly small number. Babies don’t have any, most animals don’t have any, and they likely only evolved over the last million years or so. Some of the high-level emotions that are deeply human come from these.
Scanning resolution of human tissue–both spatial and temporal–is doubling every year, and so is our knowledge of the workings of the brain. The brain is not one big neural net, the brain is several hundred different regions, and we can understand each region, we can model the regions with mathematics, most of which have some nexus with chaos and self-organizing systems. This has already been done for a couple dozen regions out of the several hundred.Recent - as in, within the last 20 years - advances in mathematics in the fields of Chaos Theory and Self-organising systems have been crucial in solving many problems, from the behaviour of flocks of birds and schools of fish, to turbulent flow out of a common household tap. We have tools now that enable us to undrestand much of what we could merely observe in the dim, dark and distant past of 1970.
"We have a good model of a dozen or so regions of the auditory and visual cortex, how we strip images down to very low-resolution movies based on pattern recognition. Interestingly, we don’t actually see things, we essentially hallucinate them in detail from what we see from these low resolution cues. Past the early phases of the visual cortex, detail doesn’t reach the brain.Meanwhile, with Psychology and Psychiatry, most medical schools are still in the "Ju Ju and Witchdoctor" stage, doing the equivalent of bleeding the patients to remove evil humours. Most, but not all. And we now have an arsenal of psychotropic drugs whose effects may be extremely crude, but still effective. The equivalent of amputations to cure gangrene, rather than antispesis and antibiotics. Still more effective than making passes with relics of saints.
"We are getting exponentially more knowledge. We can get detailed scans of neurons working in vivo, and are beginning to understand the chaotic algorithms underlying human intelligence. In some cases, we are getting comparable performance of brain regions in simulation. These tools will continue to grow in detail and sophistication.I''ll repeat one bit, one very important bit :
"We can have confidence of reverse-engineering the brain in twenty years or so. The reason that brain reverse engineering has not contributed much to artificial intelligence is that up until recently we didn’t have the right tools. If I gave you a computer and a few magnetic sensors and asked you to reverse-engineer it, you might figure out that there’s a magnetic device spinning when a file is saved, but you’d never get at the instruction set. Once you reverse-engineer the computer fully, however, you can express its principles of operation in just a few dozen pages.
"Now there are new tools that let us see the interneuronal connections and their signaling, in vivo, and in real-time. We’re just now getting these tools and there’s very rapid application of the tools to obtain the data.
"Twenty years from now we will have realistic simulations and models of all the regions of the brain and [we will] understand how they work. We won’t blindly or mindlessly copy those methods, we will understand them and use them to improve our AI toolkit. So we’ll learn how the brain works and then apply the sophisticated tools that we will obtain, as we discover how the brain works.
We can have confidence of reverse-engineering the brain in twenty years or so.But wait, there's more :
But Kurzweil doesn’t think that the future will arrive in a rush. As William Gibson observed, "The future is here, it’s just not evenly distributed."The human brain's "wetware", the physical bits, turns out to be a lot less complex than we'd ever imagined, just as the arrangements and patterns within it are even more complex.
"Sure, it’d be interesting to take a human brain, scan it, reinstantiate the brain, and run it on another substrate. That will ultimately happen."
"But the most salient scenario is that we’ll gradually merge with our technology. We’ll use nanobots to kill pathogens, then to kill cancer cells, and then they’ll go into our brain and do benign things there like augment our memory, and very gradually they’ll get more and more sophisticated. There’s no single great leap, but there is ultimately a great leap comprised of many small steps.
(Ray Kurzweil speaks) If you follow that logic, then if you were to take me ten years ago, I could not pass for myself in a Ray Kurzweil Turing Test. But once the requisite uploading technology becomes available a few decades hence, you could make a perfect-enough copy of me, and it would pass the Ray Kurzweil Turing Test. The copy doesn’t have to match the quantum state of my every neuron, either: if you meet me the next day, I’d pass the Ray Kurzweil Turing Test. Nevertheless, none of the quantum states in my brain would be the same. There are quite a few changes that each of us undergo from day to day, we don’t examine the assumption that we are the same person closely.Take a look around you. The world in only 20 years time will be quite different, yet remain much the same in many ways. We already have the first prosthetic brain part replacements. In 20 years time, we may have some really good idea of how to go about implementing a human mind on non-biological hardware. Either "copying" an existing one, or making one out of whole cloth.
"We gradually change our pattern of atoms and neurons but we very rapidly change the particles the pattern is made up of. We used to think that in the brain–the physical part of us most closely associated with our identity–cells change very slowly, but it turns out that the components of the neurons, the tubules and so forth, turn over in only days. I’m a completely different set of particles from what I was a week ago.
"Consciousness is a difficult subject, and I’m always surprised by how many people talk about consciousness routinely as if it could be easily and readily tested scientifically. But we can’t postulate a consciousness detector that does not have some assumptions about consciousness built into it.
"Science is about objective third party observations and logical deductions from them. Consciousness is about first-person, subjective experience, and there’s a fundamental gap there. We live in a world of assumptions about consciousness. We share the assumption that other human beings are conscious, for example. But that breaks down when we go outside of humans, when we consider, for example, animals. Some say only humans are conscious and animals are instinctive and machinelike. Others see humanlike behavior in an animal and consider the animal conscious, but even these observers don’t generally attribute consciousness to animals that aren’t humanlike.
"When machines are complex enough to have responses recognizable as emotions, those machines will be more humanlike than animals."
It chimed with some of my recent reading - I've just finsihed Pinker's How the Mind Works and, yesterday, I received a copy of Julian Jaynes's work The Origin of Consciousness in the Breakdown of the Bicameral MInd.

Legler had been present for the Apollo 10 simulation when the lunar module was suddenly in demand as a lifeboat. While some lifeboat procedures had already been worked out for earlier missions, none addressed having to use the lunar module as a lifeboat with a damaged command module attached. Although Legler called in reinforcements from among the other lunar module flight controllers, they were unable to get the spacecraft powered up in time, and the Apollo 10 simulation had finished with a dead crew.So this was done, and it sure came in handy later. For every quick-fix thought up in a moment of crisis, there were reams of procedures and contingency plans that had to be implemented without delay.
"Many people had discussed the use of the LM as lifeboat, but we found out in this sim," that exactly how to do it couldn't be worked out in real time, Legler says. At the time, the simulation was rejected as unrealistic, and it was soon forgotten by most everyone. NASA "didn't consider that an authentic failure case," because it involved the simultaneous failure of so many systems, explains Hannigan.
But the simulation nagged at the lunar module controllers. They had been caught unprepared and a crew had died, albeit only virtually. "You lose a crew, even in a simulation, and it's doom," says Hannigan. He tasked his deputy, Donald Puddy, to form a team to come up with a set of lifeboat procedures that would work, even with a crippled command module in the mix.
A 1969 measurement of the level of argon in the air we breathe was too low, according to a team from the Korea Research Institute of Standards and Science and the International Bureau of Weights and Measures in France.
Argon is a gas that rarely interacts chemically with anything. The 25-year-old measurement assumed that argon was 0.917 percent of the air's total composition. The new measurement, reported in a recent issue of the journal Metrologia, puts the value at 0.9332 percent.
The other contents of Earths atmosphere are nitrogen (78 percent), oxygen (21 percent), water vapor (typically about one percent), and carbon dioxide (0.04 percent). Stuff coming in at below 0.01 percent include neon, helium, methane, hydrogen, nitrous oxide, and ozone.
The new argon results imply that the air is denser by 0.01 percent. Although such a small change would seem to be insignificant, it does affect precision measurements of mass.
As episode director Joe Ahearne explained, the Dalek confronted by the Doctor and Rose (Billie Piper) is a monster for a new generation.The Mind Boggles. I'm not sure I really want to know the details there.
"The Daleks of the 1960s and 1970s would not make the grade today," he says. "They would be seen as comical rather than frightening. We couldn't have that."
Stairs have not been a problem for Daleks since 1988, when they first levitated towards Sylvester McCoy in Remembrance of the Daleks.
The new Dalek can also spin its torso independently of his head, so creeping up from behind is no longer an option. Its trademark "sink plunger" attachment also reveals a terrifying new function.
"We have taken all the perceived weaknesses of the Dalek and made them deadly," says Mike Tucker, the BBC model unit's miniature effects supervisor.Though not as deadly as SWORDS, the robot (actually a remote piloted vehicle) whose predecessor, the TALON recently saw service in Bosnia, Afghanistan and Iraq.
My advice to those who fear "pirates" in the straits is that they should bypass it; use instead alternative routes like the Straits of Sunda and Lombok or, in future, the proposed pipelines across the Isthmus of Kra.So what if it costs a few extra million, and takes an extra couple of weeks? Sailing where they are, they're just asking for it, right?
Sadly, after 9/11, even myths and half-truths are recycled to feed an angry world for strategic purposes until they become self-fulfilling.Next step, blaming an International Zionist Conspiracy.
It would not surprise me if a big accident were to be staged in the Straits of Malacca by those with sinister designs to provide evidence, to legitimise fears for their impending threat scenarios.
Indonesia and Malaysia must resist efforts by outsiders to destabilise the strategic waterway. They should not give credence to any self-prophecy with built-in ulterior motives.
Mice have been placed in a state of near suspended animation, raising the possibility that hibernation could one day be induced in humans.Nothing new under the sun? Horse Puckey, we're discovering or inventing new stuff all the time.
If so, it might be possible to put astronauts into hibernation-like states for long-haul space flights - as often depicted in science fiction films.
[...]
The researchers from the University of Washington and the Fred Hutchinson Cancer Research Center in Seattle put the mice in a chamber filled with air laced with 80 parts per million (ppm) of hydrogen sulphide (H2S) - the malodorous gas that gives rotten eggs their stink.
Hydrogen sulphide can be deadly in high concentrations. But it is also produced normally in humans and animals, and is believed to help regulate body temperature and metabolic activity.
We live in a national culture that glamorises soldiers, yet the sight of a military uniform with its obvious connotations of morbidity and violence provokes in me the question: "What sort of person is attracted to the killing professions?" Army recruiting advertisements beg the same question.That some people who are good at what they do get seduced by the "Dark Side of the Force" is incontestable: the French Foreign Legion exists, and no-one seriously believes that all who join it do so out of Francophilia.
The raising of this query in public will bring hostile responses as well as the inevitable, "If it wasn't for soldiers you wouldn't have the liberty to ask that question", as if I owe my ration of happiness, sanity or spiritual health to militarism.

Where the Prime Minister sees courage, decency and goodness in professional soldiers - all those "best and finest" qualities - I cannot help but also see the possibility of perversity, emotional sickness and a latent murderous impulse. The innocent question won't go away: "What sort of person volunteers to devote their life to the skills of destruction and the business of hunting, trapping and slaughtering humans?"
[...]
Soldiers can quickly tire of patriotism and piety in the globalised world. Many become mercenaries now and sell their souls to the highest bidder as hit-men; which may tell us something about what it takes to be a soldier. Iraq is crawling with these lapsed "best and finest" people. No doubt many of those innocent young ADF people in uniform, photographed with the leering, beer-juggling Prime Minister, may in time see the light, take to his private enterprise ideas and move on to the big bucks - to hell with the medals and to hell with the cosy car parks of Gallipoli. At the end of the day, as Socrates said: "All wars are fought for money."
One of (those) who I taught, Midshipman (at the time, later Lieutenant) Goodall, died in a helo crash recently, helping give aid to Indonesians after the recent earthquake.As for cartoonists and other propagandists, "I cannot help but also see the possibility of perversity, emotional sickness, cowardice and a latent desire to abet genocide."
The kids I taught weren't saints, nor some form of heroic ideal. They were normal but exceptionally bright kids who'd decided that Australia was worth protecting, and that someone had to do it. Just like all the other Australian military volunteers who died of enemy action, accident or disease in all parts of the world, or who returned whole and safe, or shattered in mind and body.
And to all the hard working guys and gals at GCHQ Cheltenham and the NSA boffins in Alexandria, VA who work with CARNIVORE to wade through the ECHELON intercepts of all internet traffic, we hope we haven't wasted your time too much, and maybe raised a smile as you read our imaginary plots and thought "Bloody amateurs, they should see some of the genuine stuff that crosses our desks. All their hair would turn white with shock and they wouldn't be able to fall asleep for a week".I believe it. Thanks, guys, for doing a hard job that will remain unsung for a long time, and yet still managing to preserve the majority of our privacy and freedom of speech.
eEye Digital Security has discovered a vulnerability in USER32.DLL's handling of Windows animated cursor (.ani) files that will allow a remote attacker to reliably overwrite the stack with arbitrary data and execute arbitrary code.So in summary, if you have Windows of any form from 95 to ME, and you look at the wrong website, or receive the wrong e-mail, or look at the wrong spreadsheet, word document, or powerpoint presentation, you're toast.
Because Windows animated cursors can be supplied for use by Internet Explorer, this vulnerability affects any applications that use the Internet Explorer component internally, such as Internet Explorer itself, Word, Excel, PowerPoint, Outlook, Outlook Express, and so on, as well as the Windows shell.
In the case of Internet Explorer, the user's system will be compromised when the user views a website that shows a malformed ANI file referenced via a style sheet in the HTML file. Likewise, a system may be compromised through Outlook and Outlook Express when the user tries to read an HTML e-mail containing a MIME-encoded malformed ANI file and a style sheet referencing the encoded ANI file, invoked using HTML such as < BODY style="CURSOR: url('cid:xxxx')" >. In the case of the Windows shell (explorer.exe), exploitation occurs when the user opens a folder containing a malformed ANI file.
This vulnerability also exists in all obsolete versions of the Windows operating system (Windows 95/98/NT4).
To make matters worse, the past few days, there have been a number of reports of large companies that provide shared hosting web servers, who have been compromised and their customers web pages modified to attack visitors using the exploits that this fix blocks. In other words, the hackers are starting to attack users who do not have the fix installed and have found ways to do it on a large scale. There is also a report of one known hacker site using this exploit (MS05-002) to infect visitors with two files, that only the Kaspersky AV is currently detecting.Oh yes, many problems have been reported by people with this patch, especially on older machines. This patch appears to break many non-Microsoft web browsers and other software, at least on some machines. Unfortunately for the consipracy-minded, if also breaks the competing Mirosoft products on those machines too.
So it is a real threat now and there is no other way to protect your system short of only allowing viewing in text format and never clicking on a image, icon or hyperlink.
Note that this update was issued on 11th Jan 2005 and then revised on 8th March 2005.It's not known whether there are different versions of this patch, early ones very buggy, later ones not, but if you're having trouble with a Win98 machine recently after updating this patch, try uninstalling it and getting a new version.
It's a little bit of a ritual but quite easy (just takes a lot of words to explain).Or get a friendly neighbourhood tech geek to to this for you (show them these instructions). He or she is likely to get a buzz out of helping you and another chance to demonstrate to the world their Superior Computer-Fu.
First make up an empty folder to put it into (anywhere, any name, as long as you will be able to find it later).
You then go to this website:
Windows "Coporate" Update
This looks exactly like normal Windows Update but it isn't. You go through the ritual of selecting your system and critical updates. Eventually you will find a long list poked into a fairly small box bottom right of screen.
Scroll down and you will find the number about two thirds of the way down. Put it in the shopping basket and download it. You will need to browse to the empty folder you made previously before it will download.
Once you've done all that come off line and go to the folder you made. You will then find it has made a stack of sub-folders. Just work your way through that lot until you find the file (it's called Windows98-KB891711-ENU.EXE).
I would normally say just double click it and away you go. In this instance it is sensible to heed Dan's warning in #12. (The warning reads as follows - I read in another forum today that in the "Exec Notes or something or other" that it should be installed while running in safe mode. (I haven't been anywhere else yet, so when I run across it again I'll gather more detailed info in case it's required.) - AEB) It certainly won't do any harm to install it from Safe Mode.
You probably know this, but to get to Safe Mode you either hold Ctrl key down while booting or if this doesn't work keep tapping F8 key while booting. From the startup menu that appears select Safe Mode. It will be like normal Windows but with large icons and rotten graphics. Just find the file and double click it. Re-boot afterwards.
It ain't necessarily soOddly enough, his first example, David slaying the Giant, Goliath of Gath, isn't particularly unlikely. That someone of gigantic statuture - 6ft 3in would qualify at the time - might be a Phillistine General, and Lord of Gath (then a Phillistine fief), is quire plausible. Based upon the known accuracy of much of the Hebrew Histories, military historians take this story at face value, and more probably true than not. But I digress.
It ain't necessarily so

It ain't necessarily so.

Although the amount of energy produced is small -- 20 microwatts -- it is quite impressive in relation to the tiny scale of the motor. The whole setup is less than 200 nanometers on a side, or hundreds of times smaller than the width of a human hair. If it could be scaled up to the size of an automobile engine, it would be 100 million times more powerful than a Toyota Camry's 225 horsepower V6 engine, the researchers say.Then you can Build your own South Park Character

I ask Neconie what his Indian name is. "Just Neconie," he responds. "It's an old Kiowa name. I don't have one like Standing Water, or Leaky Faucet, or anything like that." I ask him what he thinks of Churchill's Indian name, which is "Keezjunnahbeh," meaning "kind-hearted man."
Neconie shrugs. He hadn't heard of it. "But Bay Area Indians, we have our own name for him. We just call him Walking Eagle."
"Why?" I ask.
"Because," says Neconie, gathering up his placards, "a Walking Eagle is so full of s--that it can no longer fly."
