Arrivederci Kebab

Several Italian cities this past week, including Milan, took the unusual step of banning any new ethnic food outlets from opening. The Italian Minister of Agriculture, Luca Zaia, is a staunch supporter of the foreign food ban. When asked if he had ever tasted a kebab, he replied with the following:

"No – and I defy anyone to prove the contrary. I prefer the dishes of my native Veneto. I even refuse to eat pineapple."

Anniversary: Scotch Tape

On this day in 1930, 3M began marketing Scotch tape. They introduced a mascot Scotty McTape (I'm not kidding) in 1944 and the Wallace tartan-inspired plaid in 1945. 3M has a page with old ads, including the 1958 ad on the left in which Scotty McTape helps a kid who desperately needed tape: "with this slick tape to help me out my marks will all be grand!"

Last year, scientists demonstrated that peeling scotch tape in a vacuum produced x-rays powerful enough to image a finger. Sadly, it was too late for Scotty McTape, who died from excessive radiation exposure in the 1960's.

Mannahatta

This year is the quadricentennial of Henry Hudson's 1609 arrival to the island of Manhattan (the explorers first saw the island on September 12, 1609). The native Lenni Lenape called the island Mannahatta, the "land of many hills". No piece of Earth has been so transformed. Times Square, where I worked for two years, was a swamp in 1609.

The Mannahatta Project is recreating the 1609 island, its topography and ecology. They'll have displays and events throughout the year and a book is associated with the project.

Updike on Mars

In one of his final pieces, John Updike wrote about Mars for National Geographic last month. Updike previously wrote about Extreme Dinosaurs for National Geographic in 2007. At that time, he did an interview and reading, heard here.

Now the Phoenix mission, with its surpassingly intricate arm, scoop, imagers, and analyzers, takes us inches below the surface of dust, sand, and ice in Mars's north polar region. Spoonfuls of another planet's substance, their chemical ingredients volatilized, sorted, and identified, become indexes to cosmic history. Meanwhile, the Mars Reconnaissance Orbiter, the newest of three operational spacecraft circling the planet, feeds computers at the University of Arizona with astoundingly vivid and precise photographs of surface features. Some of these false-color images appear totally abstract, yet they yield to knowledgeable eyes riches of scientific information.

The dead planet is not so dead after all: Avalanches and dust storms are caught on camera, and at the poles a seasonal sublimation of dry ice produces erosion and movement. Dunes shift; dust devils trace dark scribbles on the delicate surface. Whether or not evidence of microbial or lichenous life emerges amid this far-off flux, Mars has become an ever nearer neighbor, a province of human knowledge. Dim and fanciful visions of the twinkling fire planet have led to panoramic close-ups beautiful beyond imagining.

Fox News and the 'Doomsday Machine'

For reasons known only to FoxNews.com, they consistently refer to the Large Hadron Collider as the 'Doomsday Machine'. It doesn't seem to matter if the article is about the dangers some people have suggested the LHC poses. For example, 'Doomsday Machine' Repairs to Cost $21 Million or Gala Inauguration for Broken-Down 'Doomsday Machine'. Even when the heading is appropriate, as in Scientists Not So Sure 'Doomsday Machine' Won't Destroy World, FoxNews.com keeps you guessing. Describing the relative improbability of the LHC destroying the Earth:

FoxNews.com can think of a few other things that didn't seem possible once — the theory of continental drift, the fact that rocks fall from the sky, the notion that the Earth revolves around the sun, the idea that scientists could be horribly wrong.

I have no idea what that means. But Super Collide does like the third person. Before you get too worried about Doomsday, today FoxNews.com reprinted a follow-up story from livescience.com that was originally titled Stand Down: Black Holes Won't Destroy Earth. The FoxNews.com title? Scientist Insists 'Doomsday Machine' Is Perfectly Safe. I assume this is all an elaborate joke.

More Friedman

Milton and Rose (his economist wife) Friedman's book and PBS series, both titled Free to Choose were enormously effective in popularizing free market thought and economics in general. The complete 1980 original series and the 1990 updated series are available here. It's pretty fascinating viewing. If you haven't seen it, there are a variety of celebrity introductions, including a very entertaining piece by Arnold Schwarzenegger (below), and debates at the end of each volume. In the 1990 update Friedman talks with David Brooks and James Galbraith. Here are Brooks and Galbraith more recently. Milton Friedman died in 2006. He was a keenly smart and fascinating guy, rightly celebrated and criticized. It would have been interesting to hear his thoughts on the current crisis and respond to a new flood of critics.

The World Votes

The International Foundation for Electoral Systems (IFES) provides coverage of all global elections on ElectionGuide, a great website for keeping up with international events that aren't reported by our media.

The most significant upcoming election, in terms of impact on U.S. foreign policy, will be held in Israel on February 10, 2009. In the wake of the Gaza offensive, recent polls show that Benjamin Netanyahu's Likud Party should win the most seats in the Israeli Knesset.

Frontline Updates

The most recent PBS Frontline has great features on two stories we've covered this year: The Uighurs of Guantanamo (video) and Brazil's Barack Obama (video).

One Man is an Island

Milton Friedman is one of the 20th century's great economists - Nobel prize winner and Reagan advisor, the ultimate champion of the free market. His grandson, Patri Friedman (pictured), wants to build an independent country in the ocean.

I couldn't resist the contrast though their differences are probably more generational than ideological. Patri Friedman, formerly a Google engineer, now directs the Seasteading Institute which aims to create a new ocean frontier and floating civilizations. These kinds of things generally don't end well, on land or water. The strangest example in the Wired article is the Republic of Minerva:

In 1971, real estate millionaire and committed libertarian Michael Oliver dumped large quantities of sand on two coral reefs in the South Pacific and dubbed it the Republic of Minerva, a land with "no taxation, welfare, subsidies, or any form of economic interventionism." Minerva was soon invaded by the nearby kingdom of Tonga, and it dissolved back into the ocean shortly thereafter.

You can't forget about Tonga. Friedman insists that this isn't a utopian vision and is about creating a system, using market efficiencies, to try out new governments and ideas. There are lots of historical and practical reasons to doubt it will work. But I admire his imagination and libertarian spirit. And he makes some interesting arguments (think experimental medicine and huge parties), check out the Seasteading conference here.

Anniversary: Liberation of Auschwitz

Today is the 64th anniversary of the Soviet liberation of Auschwitz. Auschwitz-Birkenau is located less than 50 miles west of Krakow, Poland. It is estimated that over one million prisoners (mostly Jews) perished at the concentration camp from 1940-1945 at the hands of Nazi barbarism.

Rudolf Franz Hoess was the commandant of Auschwitz. He lived and dined happily with his family on camp grounds as inmates were incinerated in the crematoria (sometimes while still alive) or died of starvation and disease just outside his doors. Here is an excerpt from Hoess's Nuremberg Trial affidavit:

"Still another improvement we made over Treblinka was that at Treblinka the victims almost always knew that they were to be exterminated and at Auschwitz we endeavored to fool the victims into thinking that they were to go through a delousing process. Of course, frequently they realized our true intentions and we sometimes had riots and difficulties due to that fact. Very frequently women would hide their children under the clothes but of course when we found them we would send the children in to be exterminated." (Treblinka was an extermination camp closer to Warsaw)

In November, a German newspaper published Auschwitz architectural plans that had never been seen by the public. The papers reveal much about the design of Auschwitz including detailed plans for its front gate "Arbeit Macht Frei" (Work Will Set You Free), the prisoner barracks, and the gas chambers. One map is even signed by Heinrich Himmler, the past leader of the SS.

On a personal note, I have twice visited the Auschwitz-Birkenau locale. Walking the site of mass extermination overwhelmed me, not only as a Jew but as a relative of the victims of one of humanity's darkest moments. It was during my first visit in 1997 that I dropped to my knees and wept before a display in one of the barracks. Just behind the glass was a suitcase labeled with my last name.

John Updike, RIP

The great and prolific writer John Updike died today at age 76, of lung cancer.

Updike described his famed "Rabbit" series: "The tetralogy to me is the tale of a life, a life led an American citizen who shares the national passion for youth, freedom, and sex, the national openness and willingness to learn, the national habit of improvisation...."

First Animal

Trichoplax adharens, the living member of the Placozoan phylum, is a microbe-eating blob of several thousand cells. If you looked closely, you might just see it with naked eye. This tiny, humble creature may have been Earth's first animal. Placozoa are thought to have evolved early in the development of multicellular organisms. Trichoplax likely represents the oldest living animal group.

New comparative genomics studies demonstrate that animals with bilateral symmetry (like us) split from other animals (like placozoans and jellyfish) early in metazoan evolution. This suggests, intriguingly, that a nervous system developed twice in animal history, in parallel evolution. Placozoa like Trichoplax have the genetic hardware to form a nervous system, but apparently not the inclination.

Babies and Rhythm

Scientists have used electroencephalogram (EEG) analysis on newborns to demonstrate that babies are born with rhythm. Newborns' brains responded to breaks in a rock drum rhythm, even while the babies slept. This is an interesting insight into the human love of music and may allow early recognition of brain abnormalities.

Laptop Quantum Computers

More on quantum computers. Cognitive scientist Donald Hoffman answers Edge and discusses some interesting implications of quantum computing:

Laptop QCs will make us rethink neuroscience. A few decades ago we peered inside brains and saw complex telephone switch boards. Now we peer inside brains and see complex classical computations, both serial and parallel. What will see once we have thoroughly absorbed the mind set of quantum computation? Some say we will still find only classical computations, because the brain and its neurons are too massive for quantum effects to survive. But evolution by natural selection leads to surprising adaptations, and there might in fact be selective pressures toward quantum computations.

Quantum Teleportation

Researchers have achieved quantum teleportation between ytterbium ions. The ions were entangled, meaning that information could be passed instantaneously between them and without traversing space - it is teleported. The transfer of information between ions (as opposed to photons) represents in important step in establishing quantum memory systems and quantum computing. Quantum computers could allow unbeatable encryption and incredible efficiencies for some computing tasks.

Nanosensor Tattoos

Scientists are developing nanosensors, injected like tattoo ink, that can monitor chemical levels including glucose. The nanosensors chemically determine the level of the targeted substance and fluoresce (with infrared light) to indicate concentrations. Sodium sensors are now being tested in mice.

Stem Cell Clinical Trials

The FDA has approved clinical trials with embryonic stem cells. Researchers with Geron Corporation will test safety and efficacy of stem cells in spinal cord injury patients in trials likely starting this summer. The first clinical trials represent a big step forward in stem cell research, research that has been significantly hampered by the Bush administration. Geron CEO Thomas Okarma remarked that Bush restrictions had "devastated the field".

Another biotech company ReNeuron has been approved to begin stem cell clinical trials in Britain. Their studies will focus on stroke victims.

Watching Zimbabwe Die

The situation in Zimbabwe today is even more deplorable than it was when I first posted on December 13, 2008. A raging cholera epidemic has now killed at least 2,773 people and infected 50,000 according to the United Nations. The Red Cross recently warned that the number of infections could top 60,000 by next week.

It is well past time for the international community to intervene forcefully and save an entire country from wasting away under Robert Mugabe. The West must act. Additional summits and further sanctions have no value and are merely prolonging the suffering of millions of Zimbabweans. The world can no longer stand idle and watch a nation die.

Evolution Wins in Texas, MRSA Celebrates

The Texas Board of Education has endorsed a new teaching standard that students "analyze and evaluate scientific explanations using empirical evidence, logical reasoning, and experimental and observational testing" rather than discussing the creationist-pushed "strengths and weaknesses" of scientific theories. The vote was only 8-7 to endorse scientific rigor in science teaching. And this was only the first vote. After a public comment period, a final vote is scheduled for March.

Notoriously fickle bacteria Staphylococcus aureus has ignored the preliminary nature of the vote and evolved anyway. In fact, the anarchist bacteria didn't even wait for the vote, it's been evolving for a very long time, and rapidly. Now the ST398 strain of methicillin-resistant staph has been detected in Iowa pigs and farmers, marking this strain's official arrival in the United States. This particular antibiotic-resistant bacteria is a big problem in the Netherlands where an infection from pigs has spread rapidly to infect 30% of the human population. MRSA is a growing problem in livestock and humans, in the United States and around the world. MRSA infection can be deadly in humans, particularly in vulnerable hospital patient populations.

Introduction to Genomics

Barry Schuler gives a nice introduction to genomics.

Semiconducting Ink: Flexible, Printable Chip Technology

Semiconducting ink is not new, but a new designer molecule that lacks electrons at its core is the key to a potential technological revolution in semiconducting ink. At the very least we could soon see bendable LCD screens. Antonio Facchetti, chief technology officer for Polyera, says that the soluble molecule which could be printed onto paper or plastic with a modified ink-jet printer, was created using techniques more often associated with drug research. The great leap forward is that this ink can carry a negative charge, previous semiconducting inks were only positive. The combination allows for greater energy efficiency and complexity. It will be marketed as ActivInk. No word yet on how this will affect cyber-punk tattoos.

You: Bugs and Light Bulbs

About 100 trillion microbes live on and in the average human being (for comparison, your body has only about 10 trillion cells). This silent, teeming complexity is responsible for many essential functions. Scientists are now scrutinizing the genes and metabolic products of our microbes and their correlation with disease. Burgeoning fields of metabolic profiling and human metagenomics promise to redefine our relationship with our bugs and offer new insights into health and pathology. Biologist Craig Venter gives a worthwhile overview of the big ideas in genomics and metagenomics in Seed:

It has recently been argued that the generation of large data sets is the new science. I agree only insofar as the data sets are used to ask and answer unique questions about life. It is clear to me, for example, that the only hope we have for understanding our own biology is to generate thousands of complete human genomes together with well-defined phenotypic data from the same individuals. Such data will reveal much about what is nature and what is nurture in our species. Likewise, extensive metagenomic analysis of the microorganisms associated with each of those individuals will likely reveal links between certain microbial populations and human health and disease.

If thinking of yourself as mostly bugs (as The Economist notes, the numbers alone suggest we're 90% microbes) isn't strange enough, perhaps you'd like to think of yourself as a light bulb. It turns out the human body generates roughly the same power as a 100 watt bulb. What a piece of work is a man.

Inaugural Jib-Jabbery

We sometimes joke around with MSNBC's always ridiculous and sometimes endearing Chris Matthews. Slate's Jack Shafer is not as charitable:

Nobody in TV news stir-fries his ideas and serves them to the audience faster than MSNBC's Chris Matthews. Drawing from a larder filled with old anecdotes, unreliable metaphors, wacky intuition, and superficial observations, the always-animated Matthews steers whatever's handy into the hot wok that is his brain.

Harsh but fair. Chris Matthews is a mostly benign, if inexplicable, national figure. He fits well in our buffoon politics and he probably would have improved the Senate.

Obama and Science

After 8 years of Bush, many scientists are excited for a new, science-friendly administration.

And Texas is celebrating Bush's return by resuming the evolution debate. I wonder if Mencken is available to cover it.

Impossible Art

Impossible objects are illusions in which a physically impossible object is perceived as real. Scientific American has a cool slide show of such objects including mathematician Roger Penrose's famous Penrose triangle, which he described as "impossibility in its purest form". The Lego M.C. Escher interpretations are immensely enjoyable. In Tim Noble and Sue Webster's "Dead White Trash (With Gulls)" (image above from sciam.com), light reveals the sculpture's amazing shadow.

Old-Fashioned Nanotechnology

Science writer Ed Regis, who can't like his Wikipedia page, offers an Edge answer on "good old-fashioned nanotechnology":

I specify the old-fashioned version because nanotechnology is decidedly no longer what it used to be. Back in the mid-1980s when Eric Drexler first popularized the concept in his book Engines of Creation, the term referred to a radical and grandiose molecular manufacturing scheme. The idea was that scientists and engineers would construct vast fleets of "assemblers," molecular-scale, programmable devices that would build objects of practically any arbitrary size and complexity, from the molecules up. Program the assemblers to put together an SUV, a sailboat, or a spacecraft, and they'd do it—automatically, and without human aid or intervention. Further, they'd do it using cheap, readily-available feedstock molecules as raw materials.


Regis laments the redefinition of nanotechnology to simply nanoscale chemistry and the advent of nanotechnology marketing like nano facial creams. Admitting that I don't have a comprehensive knowledge of nanotechnology's past, it seems silly and confusing to make these sorts of distinctions. Nanoscale engineering seems like a decent purview for nanotechnology. The incorporation of nano materials into everyday products and life is not simply a marketing gimmick and is likely to change many things. Some people are even very concerned about it, as in this worthwhile article Our Silver-Coated Future by Robin Marantz Henig. Beyond lamenting definitions, Regis offers a nice review of nanotechnology and some contemplation of future of the molecular assemblers.

Check out nanotech pioneer Eric Drexler's blog at metamodern.com. He has a recent post on these amazing animations of natural molecular machines - bacteriophage assembly and infection (image of one is above, credit Seyet LLC).

Different Perspectives: Satellite Photos of Obama's Inauguration, which China Censored

The Guardian UK is displaying satellite images of the mall from yesterday's inauguration. Thank you to the Guardian for the images.

For yet another angle, the BBC has reported that Chinese News Agencies edited the following passages from Obama's inaugural address:

-- world leaders who "blame their society's ills on the West"
-- "To those who cling to power through corruption and deceit and the silencing of dissent, know that you are on the wrong side of history"
-- "Recall that earlier generations faced down fascism and communism not just with missiles and tanks, but with sturdy alliances and enduring convictions." . . . the word 'communism' was censored.

A different perspective, indeed.

The Hobbit, updated

New 3-D skull analysis supports the contention that Homo floresiensis, known as "the Hobbit", was a separate species of hominid distinct from modern humans. The Hobbit was a miniature human-like creature that lived only 18,000 years ago. We discussed the Hobbit here. Stony Brook University researchers performed extensive analysis of skull samples and concluded that the Hobbit skull is consistent with a separate species. The debate continues as to whether Homo floresiensis represents a distinct species or pathological human variants, but a consensus for a separate species is building.

President Obama

"As for our common defense, we reject as false the choice between our safety and our ideals. Our founding fathers, faced with perils we can scarcely imagine, drafted a charter to assure the rule of law and the rights of man, a charter expanded by the blood of generations. Those ideals still light the world, and we will not give them up for expedience's sake. And so to all other peoples and governments who are watching today, from the grandest capitals to the small village where my father was born: know that America is a friend of each nation and every man, woman, and child who seeks a future of peace and dignity, and that we are ready to lead once more."

Inauguration

Jefferson's First Inaugural

During the contest of opinion through which we have passed the animation of discussions and of exertions has sometimes worn an aspect which might impose on strangers unused to think freely and to speak and to write what they think; but this being now decided by the voice of the nation, announced according to the rules of the Constitution, all will, of course, arrange themselves under the will of the law, and unite in common efforts for the common good. All, too, will bear in mind this sacred principle, that though the will of the majority is in all cases to prevail, that will to be rightful must be reasonable; that the minority possess their equal rights, which equal law must protect, and to violate would be oppression. Let us, then, fellow-citizens, unite with one heart and one mind. Let us restore to social intercourse that harmony and affection without which liberty and even life itself are but dreary things. And let us reflect that, having banished from our land that religious intolerance under which mankind so long bled and suffered, we have yet gained little if we countenance a political intolerance as despotic, as wicked, and capable of as bitter and bloody persecutions. During the throes and convulsions of the ancient world, during the agonizing spasms of infuriated man, seeking through blood and slaughter his long-lost liberty, it was not wonderful that the agitation of the billows should reach even this distant and peaceful shore; that this should be more felt and feared by some and less by others, and should divide opinions as to measures of safety. But every difference of opinion is not a difference of principle. We have called by different names brethren of the same principle. We are all Republicans, we are all Federalists. If there be any among us who would wish to dissolve this Union or to change its republican form, let them stand undisturbed as monuments of the safety with which error of opinion may be tolerated where reason is left free to combat it. I know, indeed, that some honest men fear that a republican government can not be strong, that this Government is not strong enough; but would the honest patriot, in the full tide of successful experiment, abandon a government which has so far kept us free and firm on the theoretic and visionary fear that this Government, the world's best hope, may by possibility want energy to preserve itself? I trust not. I believe this, on the contrary, the strongest Government on earth. I believe it the only one where every man, at the call of the law, would fly to the standard of the law, and would meet invasions of the public order as his own personal concern. Sometimes it is said that man can not be trusted with the government of himself. Can he, then, be trusted with the government of others? Or have we found angels in the forms of kings to govern him? Let history answer this question.

Bishop Gene Robinson's Inaugural Prayer



This is Gene Robinson's prayer before the inaugural concert yesterday, the first event on the inaugural calendar. Gene Robinson is the first openly gay bishop in the Episcopal Church. This prayer was not shown on television, nor even the jumbo-trons at the event that day. Organizers, including HBO, claim there was a scheduling error. Tomorrow Rick Warren will make a very different prayer than this.

Bishop Robinson continues a tradition of controversial Episcopal Bishops such as Bishop Spong, who ordained the first Female Priest in the Episcopal Church. Often I hear people referring to "Christian" culture. I wish they were referring to prayers like this.

Lincoln's Second Inaugural

Lincoln's second inaugural address is short by today's standards (and significantly shorter than his first) but is often considered the greatest inaugural address given. Lincoln would be dead just over a month after its delivery. He concludes:

With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation's wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.

First Photographs

A list of firsts in photography (h/t Andrew Sullivan). James Clerk Maxwell, father of electromagnetic theory, made the first color photograph in 1861 (pictured above, the photograph is of a tartan ribbon). Maxwell isn't as well known as other great physicists but deserves mention alongside Newton and Einstein.

Martian Methane

NASA has been studying huge "flumes" of methane, some covering an area roughly that of the continental United States, which escaped from the crust of Mars and disappeared. They can explain the 'disappearance': a chemical reaction in the atmosphere neutralizes the gas, but there are still questions about the origin of the methane.

Of course, the hope is that there is or was life on Mars. In our own deep crust there are examples of microbial life that do not rely on solar energy or oxygen to grow and multiply. Of course, there are also inorganic methods of creating Methane as well, involving water transforming olivine into serpentine. Either way, how we think about Mars is changing: NASA says the model of Mars as a crypt planet, an unchanging block of rock, is done for.

With the discovery of large equatorial glaciers, and now methane gas in abundance, Mars is looking better all the time.

Goodbye to Bush: an attempt at an assessment

President George W. Bush has repeatedly suggested that only History can judge him. The idea that history is univocal, unchanging, and belongs to a far future that won't give any credence to his critics is difficult to support, but so are many of the ideas that guided and sustained this administration -- an administration which will soon belong to the past. The president who will give his name to this era has certainly left a mark on our time, but how do we read that mark?

Insulin Gum

Chemist Robert Doyle and colleagues at Syracuse University are working on better delivery of insulin. By binding insulin to vitamin B12, researchers hope to protect insulin from destruction in the gut and allow delivery to the bloodstream. This would allow diabetics to take insulin orally, a nice improvement from injections. It might mean an insulin pill though the researchers think an insulin gum would be more effective.

As an aside, my brother had an idea for vitamin gum years ago. Vitamin gums of different types have come out but it seems that, still, none has hit big. That's surprising to me given the success of things like Airborne. Here are some vitamin gumballs.

Anniversary: Cash at Folsom Prison

On this day in 1968, Johnny Cash played two shows at Folsom State Prison in Folsom, California. The album from those shows At Folsom Prison was a big hit and reestablished Cash's popularity. The album frequently appears on lists of the greatest American albums.

Its most famous song "Folsom Prison Blues" was originally recorded in 1955. Cash started playing prisons in response to requests from prisoners after "Folsom Prison Blues" came out. The below clip is from 1959, featuring Johnny Cash and the Tennessee Two (later Three) - Luther Perkins on guitar and Marshall Grant on bass. Perkins originated the train rhythm heard in the song. He was killed in a house fire during the summer of 1968, only months after the Folsom shows.

3-D Viruses

Magnetic Resonance Force Microscopy (MRFM) is a new technique offering 100 million times the resolution of MRI and allowing researchers to see the three-dimensional structure of nanometer-size viruses and proteins.

Flying Cars

Massachusetts-based Terrafugia will test its flying car the Transition in February (see an animation below). As its name implies, the Transition has retractable wings and converts from a car to a plane. It could therefore be driven to an airport and piloted away. This model seems the most practical at the moment as true widespread car flight will require automation and considerable infrastructure. See Paul Moller's TED talk on his Skycar, a vertical takeoff flying machine.

Flying cars are probably the foremost (and cartoon) symbol of the future. But flying cars are not amenable to Moore's law as other technologies are. I don't think we'll be off the highways anytime soon. Futurist Ray Kurzweil addresses this and many other issues in this strange, fawning interview with Glenn Beck. Kurzweil makes provocative claims throughout the interview. The whole thing is really pretty bizarre as I imagine are most Glenn Beck interviews.

Cosmic Radio Mystery

NASA scientists have discovered unexpectedly loud background radio noise (h/t DJ). The ARCADE (Absolute Radiometer for Cosmology, Astrophysics and Diffuse Emission) system, a space-scraping giant balloon (see image), was searching for faint radio signals generated by heat from the universe's first stars but found a much louder, mysterious signal. Astronomers and astrophysicists are scrambling to explain the results.

Bacteria Make It Rain?

Researchers at Stockholm University in Sweden have found tiny amounts of surfactant-like compounds in the atmosphere. They believe the compounds come from ground bacteria and foster rain production.

Surfactants are amphiphilic (part water soluble, part water insoluble) compounds that reduce surface tension and allow mixing of disparate substances. Surfactants are used in detergents and ski wax and, of immediate relevance to us, our lungs. Pulmonary surfactant reduces surface tension in our lungs allowing effective ventilation. Surfactant deficiency is a big problem in premature babies.

Surfactants in clouds would help break up water molecules and encourage rain. The Stockholm researchers hypothesize that bacteria may have been selected for the ability to make it rain. Even if bacterial surfactants facilitate rainfall, it's not clear that we can assume evolutionary causation. Regardless, it's an intriguing notion - that bacteria may have long ago accomplished a long sought human ability (from rain dances to Olympic cloud seeding), to control the weather. And it's a great example of the universality of processes. The same stuff that helps us breathe may have allowed bacteria to make it rain.

Immortalized RNA and the Origins of Life

Scientists at the Scripps Research Institute have synthesized self-replicating RNA from basic chemical components and demonstrated that nonidentical RNA molecules can compete for parts with fitter RNA replicators eventually dominating. Pretty stunning stuff - organization, replication, and evolution from simple chemicals. Study head Dr. Gerald Joyce is careful to say that these RNA replicators do not represent life. But this is an extraordinary glimpse of how life might have developed.

"My Genome, My Self"

Steven Pinker on his involvement with the Personal Genome Project (PGP) and the future and meaning of personal genomics. Quote:

Individual genes are just not very informative. Call it Geno’s Paradox. We know from classic medical and behavioral genetics that many physical and psychological traits are substantially heritable. But when scientists use the latest methods to fish for the responsible genes, the catch is paltry.

Take height. Though health and nutrition can affect stature, height is highly heritable: no one thinks that Kareem Abdul-Jabbar just ate more Wheaties growing up than Danny DeVito. Height should therefore be a target-rich area in the search for genes, and in 2007 a genomewide scan of nearly 16,000 people turned up a dozen of them. But these genes collectively accounted for just 2 percent of the variation in height, and a person who had most of the genes was barely an inch taller, on average, than a person who had few of them. If that’s the best we can do for height, which can be assessed with a tape measure, what can we expect for more elusive traits like intelligence or personality?

Who's the Boss? (Playoffs)

Boss and I both like Tennessee (-3) and Carolina (-10) today.

 
 
 
 
 
 

The Singularity

The singularity, the name given to a future union of human intelligence and technology, is a much celebrated and reviled idea. Lots of people are dismissive of or terrified by notions of smarter-than-human machines and transhumanism.

But it's pretty hard to argue with history and the incredible pace of technological advance. Moore's law, the exponential growth of computing capacity (the doubling of the transistors on new integrated circuits every two years), implies an enormously changed world over the next fifty years. Something like "the singularity" seems esoteric and shocking to most people. But we incorporate technological change pretty smoothly. The current internet would have seemed crazy to people twenty years ago (imagine showing them Google Earth on an iPhone). So when Marshall Brain, founder of HowStuffWorks, makes claims that we'll have $500 boxes with human-level intelligence by 2042 (if not earlier), I tend to take it seriously and think maybe he's being cautious. His provocative talk (including a sneery audience dissent at the end) from The Singularity Summit is below:



UPDATE: Several people (including DJ via phone) have pointed out the reductionist economics in Brain's talk. I agree that Brain does not address the complexities of the effects he describes. I still think it's an interesting and worthwhile talk, largely because it is provocative. The implications of accelerating technological advance are not discussed very often. Linuxguy33 points to this worthwhile review of The Singularity Summit (with a highly critical review of Brain's talk).

Biggest Moon of 2009

Tomorrow night the full Moon will appear bigger in the night sky than during any other time in 2009. Saturday's perigee Moon represents the Moon's closest approach in its elliptical orbit. A slightly larger appearing perigee Moon was seen last month (see photo). The Moon's proximity significantly brightens the night and mildly increases the tides.

Homo evolutis

Juan Enriquez thinks that speciation is coming:

Speciation will not be a deliberate, programmed event. Instead it will involve an ever faster accumulation of small, useful improvements that eventually turn homo sapiens into a new hominid. We will likely see glimpses of this long-lived, partly mechanical, partly regrown creature that continues to rapidly drive its own evolution. As the branches of the tree of life, and of hominids, continue to grow and spread, many of our grandchildren will likely engineer themselves into what we would consider a new species, one with extraordinary capabilities, a homo evolutis.

Doom and Gloom

With another half million jobs lost in December, the 2008 total is 2.6 million jobs gone. The December results pushed unemployment to 7.2%, the highest in 16 years. Dr. Doom says more doom ahead:

This crisis is not merely the result of the U.S. housing bubble’s bursting or the collapse of the United States’ subprime mortgage sector. The credit excesses that created this disaster were global. There were many bubbles, and they extended beyond housing in many countries to commercial real estate mortgages and loans, to credit cards, auto loans, and student loans. There were bubbles for the securitized products that converted these loans and mortgages into complex, toxic, and destructive financial instruments. And there were still more bubbles for local government borrowing, leveraged buyouts, hedge funds, commercial and industrial loans, corporate bonds, commodities, and credit-default swaps—a dangerous unregulated market wherein up to $60 trillion of nominal protection was sold against an outstanding stock of corporate bonds of just $6 trillion.

Taken together, these amounted to the biggest asset and credit bubble in human history; as it goes bust, the overall credit losses could reach as high as $2 trillion. Unless governments move with more alacrity to recapitalize banks and other financial institutions, the credit crunch will become even more severe. Losses will mount faster than companies can replenish their balance sheets.

Senator Matthews?

Looks like Hardball host and idiom machine Chris Matthews will not be running for Arlen Specter's Pennsylvania Senate seat in 2010. That is, if he doesn't have an ace in the hole, or up his sleeve. In any case, a bad worker always blames their tools. And we're not talking about rearranging the deckchairs on the Titanic.

Flower Insulin

Insulin grown in safflowers is being used in patients for the first time. Human insulin genes were incorporated into the plant producing a precursor to insulin. The precursor pro-insulin can be enzymatically modified to usable insulin.

The BCS, continued

Bill James hates the BCS too and calls for a statisticians to boycott the ridiculous computer system.

By the way, I'll take Florida (-5) against Oklahoma tonight. USC is probably the best team in the country. A playoff would have been outstanding this year.

Enter Gene Therapy

Gene therapy, the manipulation of DNA typically by exploiting viral vectors, is an elegant but so far impractical disease intervention. Scientists manipulate viral genomes, adding therapeutic genes, and then allow the virus to do its natural work of adding the engineered changes to human DNA. Two cancer drugs coming out in 2009 utilize this "Trojan horse" delivery and could herald the era of practical gene therapy.
