jagadish chandra bose

Wikipedia | Sir Jagadish Chandra Bose CSI CIE FRS (Bengali: জগদীশ চন্দ্র বসু Jôgodish Chôndro Boshu) (November 30, 1858 – November 23, 1937) born in a Bengali Hindu Kayasth family was a polymath: a physicist, biologist, botanist, archaeologist, and writer of science fiction.[1] He pioneered the investigation of radio and microwave optics, made very significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent.[2] He is considered one of the fathers of radio science,[3] and is also considered the father of Bengali science fiction. He was the first person from the Indian subcontinent to get a US patent, in 1904.

Born during the British Raj, Bose graduated from St. Xavier's College, Calcutta. He then went to the University of London to study medicine, but could not complete his studies due to health problems. He returned to India and joined the Presidency College of University of Calcutta as a Professor of Physics. There, despite racial discrimination and a lack of funding and equipment, Bose carried on his scientific research. He made remarkable progress in his research of remote wireless signaling and was the first to use semiconductor junctions to detect radio signals. However, instead of trying to gain commercial benefit from this invention Bose made his inventions public in order to allow others to develop on his research. Subsequently, he made some pioneering discoveries in plant physiology. He used his own invention, the crescograph, to measure plant response to various stimuli, and thereby scientifically proved parallelism between animal and plant tissues. Although Bose filed for a patent for one of his inventions due to peer pressure, his reluctance to any form of patenting was well known. He is being recognised for many of his contributions to modern science.

He forwarded a theory for the ascent of sap in plants in 1927, his theory contributed to the vital theory of ascent of sap. According to his theory, electromechanical pulsations of living cells were responsible for the ascent of sap in plants.

He was skeptical about the then, and still now, most popular theory for the ascent of sap, the tension-cohesion theory of Dixon and Joly, first proposed in 1894. The 'CP theory', proposed by Canny in 1995,[18] validates this skepticism. Canny experimentally demonstrated pumping in the living cells in the junction of the endodermis.

In his research in plant stimuli, he showed with the help of his newly invented crescograph that plants responded to various stimuli as if they had nervous systems like that of animals. He therefore found a parallelism between animal and plant tissues. His experiments showed that plants grow faster in pleasant music and their growth is retarded in noise or harsh sound. This was experimentally verified later on[citation needed].

His major contribution in the field of biophysics was the demonstration of the electrical nature of the conduction of various stimuli (wounds, chemical agents) in plants, which were earlier thought to be of a chemical nature. These claims were experimentally proved by Wildon et al. (Nature, 1992, 360, 62–65). He also studied for the first time action of microwaves in plant tissues and corresponding changes in the cell membrane potential, mechanism of effect of seasons in plants, effect of chemical inhibitor on plant stimuli, effect of temperature etc. He claimed that plants can "feel pain, understand affection etc.," from the analysis of the nature of variation of the cell membrane potential of plants, under different circumstances.

carl jung and the holy grail of the unconscious

NYTimes | Carl Jung founded the field of analytical psychology and, along with Sigmund Freud, was responsible for popularizing the idea that a person’s interior life merited not just attention but dedicated exploration — a notion that has since propelled tens of millions of people into psychotherapy. Freud, who started as Jung’s mentor and later became his rival, generally viewed the unconscious mind as a warehouse for repressed desires, which could then be codified and pathologized and treated. Jung, over time, came to see the psyche as an inherently more spiritual and fluid place, an ocean that could be fished for enlightenment and healing.

Whether or not he would have wanted it this way, Jung — who regarded himself as a scientist — is today remembered more as a countercultural icon, a proponent of spirituality outside religion and the ultimate champion of dreamers and seekers everywhere, which has earned him both posthumous respect and posthumous ridicule. Jung’s ideas laid the foundation for the widely used Myers-Briggs personality test and influenced the creation of Alcoholics Anonymous. His central tenets — the existence of a collective unconscious and the power of archetypes — have seeped into the larger domain of New Age thinking while remaining more at the fringes of mainstream psychology.

A big man with wire-rimmed glasses, a booming laugh and a penchant for the experimental, Jung was interested in the psychological aspects of séances, of astrology, of witchcraft. He could be jocular and also impatient. He was a dynamic speaker, an empathic listener. He had a famously magnetic appeal with women. Working at Zurich’s Burghölzli psychiatric hospital, Jung listened intently to the ravings of schizophrenics, believing they held clues to both personal and universal truths. At home, in his spare time, he pored over Dante, Goethe, Swedenborg and Nietzsche. He began to study mythology and world cultures, applying what he learned to the live feed from the unconscious — claiming that dreams offered a rich and symbolic narrative coming from the depths of the psyche. Somewhere along the way, he started to view the human soul — not just the mind and the body — as requiring specific care and development, an idea that pushed him into a province long occupied by poets and priests but not so much by medical doctors and empirical scientists.

rubbing, rubbing, rubbing.....,

organelle | What transforms the relatively benign grasshopper into the apocalyptic swarms of soldiers we call locusts is a simple thing: proximity to other grasshoppers initiated by feeding behavior.
From Wikipedia (locust):

“Research at Oxford University has identified that swarming behaviour is a response to overcrowding. Increased tactile stimulation of the hind legs causes an increase in levels of serotonin. This causes the locust to change color, eat much more, and breed much more easily. The transformation of the locust to the swarming variety is induced by several contacts per minute over a four-hour period. It is estimated that the largest swarms have covered hundreds of square miles and consisted of many billions of locusts.” (italics added)

From WIkipedia (Desert Locust):


“When vegetation is distributed in such a way that the nymphs, usually called hoppers, have to congregate to feed, and there has been sufficient rain for a lot of eggs to hatch, the close physical contact causes the insects’ hind legs to bump up against one another. This stimulus triggers a cascade of metabolic and behavioral changes that cause the insects to transform from the solitary form to the gregarious form.”
From Arundhati Roy:
“It is not a coincidence that the political party that a carried out the Armenian genocide in the Ottoman Empire was called the Committee for Union and Progress. “Union” (racial/ethnic/religious/national) and “Progress” (economic determinism) have long been the twin coordinates of genocide.

Armed with this reading of history, is it reasonable to worry about whether a country that is poised on the threshold of “progress” is also poised on the threshold of genocide? Could the India being celebrated all over the world as a miracle of progress and democracy possibly be poised on the verge of committing genocide?

The mere suggestion might sound outlandish and at this point in time, the use of the word genocide surely unwarranted. However, if we look to the future, and if the Tsars of Development believe in their own publicity, if they believe that There is No Alternative to their chosen model for Progress, then they will inevitably have to kill, and kill in large numbers, in order to get their way.

In bits and pieces, as the news trickles in, it seems clear that the killing and dying has already begun.”

koreans rubbing their hind legs..,


Video - North Korean leg rubbing.

BBCNews | Tuesday's KCNA reports announcing the severing of all ties - including communications - said the North was also banning South Korean ships and planes from its territorial waters and airspace.

"The Committee for the Peaceful Reunification of Korea... formally declares that from now on it will put into force the resolute measures to totally freeze the inter-Korean relations, totally abrogate the agreement on non-aggression between the North and the South and completely halt the inter-Korean cooperation," KCNA reported.

Pyongyang has also accused South Korea of trespassing in its waters.

In a warning to South Korea's navy, a newsreader on North Korean state television (KRT) said: "South Korean puppet army gangs have been recently trespassing our territorial waters without restraint.

"They have conducted provocative acts which severely irritate us, by making dozens of warships intrude upon our waters from 14 to 24 May."

The newsreader said that if this "deliberate provocation" continued, the North would "put into force practical military measures to defend its waters".

North and South Korea are technically still at war after the Korean conflict ended without an armistice in 1953.

While there were hopes of a reconciliation a few years ago, relations have been deteriorating since then and now appear to be at their lowest point in a decade, correspondents say. Fist tap Nana.

The average insect can easily generate a communications burst of less than 1 second which contains more information than the entire internet. Humans, it turns out, are made to receive these transmissions. The problem is that humans think that -representations- like text and video are interesting. They can no longer understand -the living media-. In point of fact, most of them cannot and (in order for their adopted creeds to retain authority) must not believe in it.

The Scientist | Last month's blowout of British Petroleum's Deepwater Horizon oil well -- which caused the US Commerce Department to decree today (25th May) that fisheries in three states bordering the Gulf of Mexico are official disasters -- is likely already impacting the Gulf's microscopic denizens, which will, in turn, have long-term effects on commercially important species such as fish and shrimp, scientists say.

Images of oil-soaked sea gulls and tar coated turtles, which typically follow major oil spills, are starting to materialize in the Gulf, but bacterial populations are likely to boom in response to the release of millions of gallons of oil, Monty Graham, biological oceanographer at the Dauphin Island Sea Lab off the coast of Alabama, told The Scientist.

Bacteria could benefit from the oil spill, Graham argued, because some bacterial species and lineages view a massive oil spill as a veritable cornucopia of delicious hydrocarbons, not a catastrophe.

The boon to bacteria most likely has ramifications that will ripple throughout marine food webs in the Gulf, especially at prominent nodes where commercially important species such as fish, crabs, and shrimp, reside. What those ramifications are, however, remain as murky as the huge plumes of oil recently discovered hovering just below the surface of Gulf waters.

Researchers who study microbial and planktonic ecosystems in the Gulf of Mexico are anxiously anticipating the effects of what may be the biggest oil spill ever. Recently uncovered evidence of oxygen depletion near those plumes (an indication that bacterial respiration is occurring en masse) indicate that a bacterial bloom is ramping up.

Normally in the Gulf, as in other oceanic ecosystems, the base of the food web is provided by photosynthetic, one-celled organisms called phytoplankton. Sunlight fuels phytoplankton growth, small crustaceans called copepods dine on phytoplankton, fish larvae (and larvae from other species) dine on copepods, small fish dine on larval organisms, and so forth and so on.

Bacteria normally exist in a semi-self-contained food web called the "microbial loop." But if they expand dramatically, these new gobs of organic matter could attract hungry, one-celled heterotrophs called nanoflagellates, which could feed slightly larger ciliates, which would then be fed upon by copepods, thus entering the normal food web that ends in commercially or recreationally important species, such as the Red Drum. In theory, this extra organic matter could help compensate for the loss of phytoplankton, since photosynthesis rates (and thus phytoplankton) may decline due to decreased sunlight penetration through oily water. However, by the time that bacteria-driven energy reaches the upper trophic levels of the food web, it has gone through more steps along the way than the energy stemming from phytoplankton. Since energy is lost at each level, adding extra levels means less energy makes its way to the big eaters.

for BP to survive, the gulf must die...,


Video - BP relies on top kill

DailyKOS | It's become increasingly obvious that everything BP says or does at this point is being vetted through the prism of litigation strategy.
While BP struggles to stop the oil gushing from its exploded well in the Gulf of Mexico, lawyers throughout the New Orleans area are gearing up for what could be the biggest environmental and maritime litigation case the nation has ever seen.

Defense firms have been working their oil and gas contacts to position themselves as local counsel for corporations with exposure to the April 20 explosion and subsequent sinking of the Deepwater Horizon drilling rig. And plaintiffs attorneys formed a litigation group and immediately chartered planes to photograph the fire on the rig, began collecting water and air samples, and started advertising to sign up clients. More clients increase the potency of the suit, allowing attorneys to collect more fees.
* Dartagnan's diary :: ::*

That's why they initially sent their minions to the Louisiana Coast to bilk poor Cajun watermen out of their ability to sue. That's when they thought the damage could be contained from a financial perspective. That was Plan "A."

"Plan "A" is long since moot.

I would argue that at this point in the disaster the die is cast, and it makes little if no difference to BP's ability to operate as a going concern whether the gushing volcano is stopped now or months from now. The sheer magnitude of the lawsuits is going to be staggering--think of the hundreds of billions of dollars in permanently despoiled property alone. All of these claims will ultimately find their way to BP's door, or the door of their excess insurance carriers.

Which is why it makes sense, from the standpoint of defending itself, for BP not to stop the gushing, and in fact to take half-measures which by their very nature will not succeed, yet prolong the appearance of BP "making an effort." The nature of this type of liability litigation practically demands that BP do this to survive.

If BP were able to stop the flow of oil through either its "top hat," "junk shot," or any of the other creative methods being bandied about, the line of attack at trial would be "Why weren't you able to do this sooner?" That's an argument that BP, with all of its hired experts, can never win. The sole question the plaintiff's lawyers will rely on (in addition to their case on causation of the explosion itself) will be "Was the technology available to stop this a month earlier?" The answer is obvious--yes, it was. Of course it was.

"Then, BP, why didn't you employ that method sooner?"

environmental group compromised?


Video - Nature Conservancy PSA.

WaPo | In the days after the immensity of the oil spill in the Gulf of Mexico became clear, some Nature Conservancy supporters took to the organization's Web site to vent their anger.

"The first thing I did was sell my shares in BP, not wanting anything to do with a company that is so careless," wrote one. Another added: "I would like to force all the BP executives, the secretaries and the shareholders out to the shore to mop up oil and wash the birds." Reagan De Leon of Hawaii called for a boycott of "everything BP has their hands in."

What De Leon didn't know was that the Nature Conservancy lists BP as one of its business partners. The Conservancy also has given BP a seat on its International Leadership Council and has accepted nearly $10 million in cash and land contributions from BP and affiliated corporations over the years.

"Oh, wow," De Leon said when told of the depth of the relationship between the nonprofit group she loves and the company she hates. "That's kind of disturbing."

The Conservancy, already scrambling to shield oyster beds from the spill, now faces a different problem: a potential backlash as its supporters learn that the giant oil company and the world's largest environmental organization long ago forged a relationship that has lent BP an Earth-friendly image and helped the Conservancy pursue causes it holds dear.

The crude emanating from BP's well threatens to befoul a number of alliances between energy conglomerates and environmental nonprofits. At least one group, Conservation International, acknowledges that it is reassessing its ties to the oil company, with an eye toward protecting its reputation.

"This is going to be a real test for charities such as the Nature Conservancy," said Dean Zerbe, a lawyer who investigated the Conservancy's relations with its donors when he worked for the Senate Finance Committee. "This not only stains BP, but, if they don't respond properly, it also stains those who have been benefiting from their money and their support."

Some purists believe environmental groups should keep a healthy distance from certain kinds of corporations, particularly those whose core mission poses risks to the environment. They argue that the BP spill shows the downside to what they view as deals with the devil.

On the other side are self-described pragmatists who, like the Conservancy, see partnering with global corporations as the best way to create large-scale change.

resistance IS futile....,


Video - Ant adventures.

The Scientist | In the absence of mating flights by airborne queens, how do Argentine ants form a new society -- one with a different clannish identity? The book posits for the first time an intriguing new hypothesis: that they don't. This would mean that the Argentine ants that made their way to California are simply an extension of the ant society from whence they came and that there are no truly new colonies.

When the expanding mass of ants bud off a new nest, all its members can mix freely with residents of the nests from whence they came, even if separated by continents. The only way for another colony to appear is for a fragment of a different colony, complete with queens and workers, to arrive at that spot, probably brought on another boat or in a car. Before humans introduced these reliable means of transportation, Argentine ants could only make such long-distant moves by rafting on floating debris in Argentine rivers. This early method of "jump dispersal" yielded the intricate patchwork of colonies that exist in Argentina, but until recently confined the species there.

Argentine ants worldwide therefore identify with limited number of colonies that continue indefinitely and are strongly inbred. Each of the California supercolonies for example must have originated from a different colony in Argentina, with its own social identity. Each is able to associate only with the populations it spins off and with its mother colony and not with members of other supercolonies.

It is reasonable, then, to think of California's four supercolonies as nothing less than the very same societies that invaded the state starting 100 years back. Whereas most ant colonies go through a lifecycle similar to that of an organism -- being born when a queen rears her first brood and dying when the queen dies -- the Argentine ant societies have achieved a kind of immortality.

What's more, a supercolony's ability to span space and time forces scientists to reconsider our concept of individuality. Like the protagonist of Gogol's story "The Nose," we don't expect our body parts to wander off. But because Argentine ants move freely within each supercolony and produce offspring that identify with the colony they came from, they spread a nationality. Leapfrogging here and there, each society recreates itself in fragments. New Zealand contains a supercolony now known to be identical to Very Large Colony in California. No surprise: since Very Large Colony controls the port cities from north (Richmond, Oakland, San Francisco) to south (Long Beach, Los Angeles, and San Diego), its ants would have easily hitched a ride to New Zealand on any of a number of ships.

Supercolonies confound our notions about societies, populations and species like nothing else. An Argentine ant society is separated socially and reproductively from all other Argentine ants by an intolerance of outsiders. Their patriotism is so absolute that males are almost always killed if they enter the territory of the next supercolony. That differs from people, whose cultures, albeit often violent toward each other, have a history of interbreeding that unifies our species. Since there's almost no reproduction between supercolonies, each society effectively exists in isolation, as genetically separate as lions are from tigers.

In a very real sense, then, each Argentine ant supercolony is its own species. If the ideas in Adventures Among Ants are correct, this is a previously overlooked means of fashioning a species.

pentagon to superbugs: resistance is futile

Wired | Common antibiotics work by attaching to a specific molecule (like an enzyme) inside bacterial cells. With some minor adaptive changes, bacteria can alter their cell structure to prevent antibiotic binding, thereby becoming resistant to the drugs. Some infections even develop “persister cells,” which stop growing when the antibiotics are administered, and then turn back on once a round of meds is completed.

But Tew and his team have developed antibiotics that work from the outside to quickly destroy bacterial cells. The drugs work by poking holes in bacterial membranes, killing the cells instantly. Within a few hours, the antibiotics are able to kill off entire colonies of bacterial pathogens. And resistance is futile: Because the meds don’t enter the actual cell, it’s impossible for the bacteria to fight back through structural adaptation.

The method has already proven effective in clinical trials for treating staph infections, and the Pentagon is betting it’ll be effective in combating Iraqibacter too. In 2009 alone, they doled out nearly $8 million to UMass and PolyMedix, to “study its antibiotic compounds for other biodefense applications and bacterial infections.”

Right now, the group is starting animal studies of Iraqibacter antibiotics, though Tew anticipates that human application is several years off. The scientists are also involved in preliminary research on using the membrane-puncture method to address other strains of bacteria.

But a means of mitigating antibiotic-resistant bacteria can’t come a moment too soon. Just last month, federal health officials warned that if resistance keeps growing, Americans could soon be living in “a post antibiotic era.”

gut intelligence


Video - humorous probiotic propaganda.

organelle | Just as the diversity of commensal microbiota and other conditions of intra-cellular, organ and metabolic health dramatically affect both our mental function and our immune system, our planet has similar features and capacities which until very recently depended upon extant biodiversity for their robust protective, relational, nutritive and prophylactic activity.

The shocking and incredibly sudden damage we have inflicted upon biospheric diversity (primarily at the scale of animals and ecosystems) has severely impacted planetary health and healing, creating in effect a exploding crisis in which protections which have long been active have suddenly and egregiously disappeared. The biodiversity we’ve erased previously acted as shock-absorbers, communications and intelligence assets, and an immunity system.

We should pause to note that Earth’s experience of time differs dramatically from our own, and to her only some few heartbeats have passed, while for us it has been 500 years. Effectively, she is in shock, and her temperature will fluctuate wildly, her inner clock has gone haywire, and she shall certainly shiver, shake and bleed. Her heartbeat, metabolic status and ‘blood pressure’ are also fluctuating wildly.

The results of these events are feeding back into every species on the planet — since we are not ‘part’ of Earth, but instead living instances of Earth. This then feeds back into the planet, and the resultant reflexive cycle creates a recursively expanding nightmare with terrifying consequences including but not limited to ‘auto-immune’ disorder on a planetary scale. This means simply ‘the elements of her body will attack each other, failing to recognize itself as self’ —just as we have done to the other species of the world.

The biodiversity which required millenia to establish cannot be ‘healed’ — it is gone and there is no ‘pill’ or ‘therapy’ that can replace it. In fact, if history is any measure, what will happen once the various nations realize what they are up against is the wholesale erasure of the remaining resources in the hope of stockpiling survival assets for specific groups of people and nations. A part of this activity is sure to include another infamous facet of human capacity: the wartime ‘denial of assets to the enemy’ move which stipulates that assets one cannot acquire for themselves or allies be destroyed or poisoned so that others cannot use them against you. This is not the future I am speaking of, but the present.

Could it be that as we annihilated the anciently conserved commensal bacterial symbionts in our own guts with antibiotics and other toxins, we set ourselves up to become omnicidal maniacs who could no longer recognize ourselves in the eyes and bodies of the creatures and ecosystems that comprise our most ancient and treasured symbionts?

Unfortunately, we shall now we shall see firsthand what ‘multiple sudden opportunistic infections’ look like at the scale of a world, rather than that of a person, or a people.

gut instinct


Video - hookworm lifecycle papermation.

Guardian | The research that so excited Lawrence was a development of the so-called "hygiene hypothesis". This theory, first developed by David P Strachan in the British Medical Journal in 1989, suggests that many of the "modern" illnesses that have grown exponentially in industrialised western countries – allergies, asthma, type 1 diabetes, Crohn's disease, irritable bowel syndrome, multiple sclerosis and possibly rheumatoid arthritis and autism, and others – are the result of inappropriate autoimmune responses. The development of chlorinated drinking water, vaccines, antibiotics, and the sterile environment of early childhood have, the argument goes, as well as preventing infection also upset the balance of the body's internal ecology. Inflammatory responses that evolved through millions of years in the certain presence of "old friends" – parasites and bacteria – have been thrown wildly out of kilter in their absence, causing autoimmune illnesses, in which the body's immune system turns on itself, and oversensitivity to harmless antigens such as pollen, or dust, or cats, or particular food groups.

The story that most interested Lawrence was the ongoing research of Professor David Pritchard, an immunologist at Nottingham University. While in the field in Papua New Guinea in the late 1980s, Pritchard noted that patients infected with the Necator americanus hookworm were rarely subject to the whole range of autoimmune-related illnesses, including hay fever and asthma. In the years since, Pritchard had developed a thesis to support this observation through painstaking clinical trials (which began after he infected himself with 50 hookworm). The thesis proved that hookworm, in small numbers, seemed able to regulate inflammatory immune responses in their hosts. (Dr Rick Maizels, at Edinburgh University, has subsequently identified the process – involving the white T-cells in the blood that regulate immunity – that allowed this to happen.)

"When I read that stuff," Lawrence recalls, "everything immediately made sense to me. In our obsession with cleansing and sterility, with the eradication of parasites, we had thrown the baby out with the bath water. The central idea is that our bodies have an internal ecosystem. One of the ironies of this, to me, is that everyone is concerned about biodiversity in the outside world, and saving the rainforest, but we've also screwed up the biodiversity inside us."

And so Jasper Lawrence set out on what became a compulsive and somewhat desperate quest. Despite the fact that perhaps one billion people in the world still live with hookworm, getting infected in the developed western world is not an easy thing. The drift of our culture has long been to eradicate parasites – or "symbions", as Lawrence prefers. To begin with, he tried to get accepted as a participant on one of the various studies investigating the phenomenon. But when that proved fruitless he determined to go to Africa and become infected.

Prior to this trip, he recalls, he contacted "all the clever people I knew who worked in medicine. I sent them all the research and asked them their opinion. They all said the same thing: 'Yes, it appears safe, but I would not advise you to do this; you need to wait 20 or 30 years for all the studies to come in. For a molecule to be identified and a drug to be tested…'"

You don't have to talk to Lawrence for long to realise he is not a man who might be prepared to wait 20 or 30 years for anything. Instead, he took a plane to Cameroon.

The life cycle of Necator americanus is not an attractive one. Hookworm infiltrate a new human host when larvae, hatched in human excrement, penetrate the soles of the feet, enter the bloodstream, travel through the heart and lungs and are swallowed when they are coughed up from the pharynx. Only in the small intestine do they mature into adults (just under 1cm long), where they can live an average of five years latching on to the intestinal wall, siphoning off tiny amounts of blood, and – this is the crucial part – "regulating the volume" of immune responses. They mate inside the host, with females laying up to 30,000 eggs per day, up to 50m eggs during a lifetime, which pass out in faeces. In the tropics, in places where there is an absence of both toilets and shoes, extreme cases of hookworm kill 70,000 people a year, and afflict many others with anaemia; they exacerbate malnutrition and stunted growth in children. There are crucial caveats to these scare stories, however. Hookworm cannot and do not replicate in the gut. They are not infectious. In small numbers they are considered harmless, and very easily eradicated. And their life cycle is fatally interrupted by the introduction of either shoes or plumbing.

not chemisty, but computer power


Video - positives and negatives of the breakthrough.

Guardian | Freeman Dyson, the physicist, captured the full range of academic sentiment in this dry appraisal: "This experiment is clumsy, tedious, unoriginal. From the point of view of aesthetic and intellectual elegance, it is a bad experiment. But it is nevertheless a big discovery… the ability to design and create new forms of life marks a turning point in the history of our species and our planet."

Venter's ego and his preference to turn to corporations rather than research foundations as funding partners (Exxon Mobil is a $600m sponsor of his energy experiments) do not tend to endear him to the academic establishment. Steve Jones, professor of genetics at University College London, and a perennial voice of reason, offered me this verdict on the biologist's latest headlines.

"It's very easy to mock Venter," Jones suggests. "When he first appeared, people just kind of sneered at him. But they stopped sneering when they saw his brilliance in realising that the genome was not a problem of chemistry but a problem of computer power. I don't think anybody can deny that that was a monumental achievement and he has been doing fantastically interesting things subsequently with marine life. Having said that, though, the man is clearly a bit of a prick and one with a serial addiction to publicity."

Jones is sceptical about the hyperbole of breathless headlines. "The idea that this is 'playing God' is just daft. What he has done in genetic terms would be analogous to taking an Apple Mac programme and making it work on a PC – and then saying you have created a computer. It's not trivial, but it is utterly absurd the claims that are being made about it."

Stewart Brand, the ecological visionary and creator of the Whole Earth Catalog, is more persuaded. Brand has got to know Venter over the last couple of years through John Brockman's Edge initiative which brings together the world's pioneering minds. What differentiates Venter from many of his peers, Brand believes, is that he is not only a brilliant biologist, but also a brilliant organisational activist. "A lot of people can think big but Craig also has the ability to fund big: he doesn't wait for grants, he just gets on and finds a way to do these things. His great contribution will be to impress on people that we live in this vast biotic of microbes. What he has shown is that microbial ecology is now where everything is at."

Brand once suggested that "we are as gods and we might as well get good at it". That statement has gained greater urgency with climate change, he suggests. "Craig is one of those who is rising to the occasion, showing us how good we can be."

a short course on synthetic genomics

Edge | On July 24, 2009, a small group of scientists, entrepreneurs, cultural impresarios and journalists that included architects of the some of the leading transformative companies of our time (Microsoft, Google, Facebook, PayPal), arrived at the Andaz Hotel on Sunset Boulevard in West Hollywood, to be offered a glimpse, guided by George Church and Craig Venter, of a future far stranger than Mr. Huxley had been able to imagine in 1948.

In this future — whose underpinnings, as Drs. Church and Venter demonstrated, are here already — life as we know it is transformed not by the error catastrophe of radiation damage to our genetic processes, but by the far greater upheaval caused by discovering how to read genetic sequences directly into computers, where the code can be replicated exactly, manipulated freely, and translated back into living organisms by writing the other way. "We can program these cells as if they were an extension of the computer," George Church announced, and proceeded to explain just how much progress has already been made. ...

constructive biology

Edge | As creative as we become, and as industrious and as good as we are at designing and manufacturing living things, which we've been doing since the stone age — no matter how good we get at that, it's like calling a candle a supernova. A candle is not a super nova; it's not even in the same league. And we, as intelligent designers, are not in the same league as the "Intelligent Designer" that designed the whole shebang. We're not designing sub-atomic particles from scratch; we're not designing the Big Bang. We're really not even designing life; we're just manipulating it.

Think of the cell as operating system, and engineers taking the place of traditional biologists in retooling stripped down components of cells (bio-bricks) in much the vein as in the late 70s when electrical engineers were working their way to the first personal computer by assembling circuit boards, hard drives, monitors, etc. It's not an accident that the phrase "bio-hackers" is in the conversation, as this new crowd has a lot in common with the computer engineers who were around the homebrew computer club of the '70s leading the development of the personal computer.

Central to this move to engineer biology, to synthesize life, is Harvard researcher George Church.

"Today I am involved in a number of synthesis and sequencing endeavors," he says. "First, the BioFab group works together on 'constructive biology', which has a number of tightly overlapping parts of a Venn diagram."

"There's IGEM, 'International Genetically Engineered Machines' group, which is now in its fourth year , and has 39 universities involved. It's a very interesting social phenomenon; it involves wiki's and a lot of undergraduates, 39 teams of 10 to 20 people each. It's amazingly intense and enjoyable — kind of like the robot competitions, or the DARPA Grand Challenges. They compete to make cool things during the summer, and some go year-round working on those cool things — engineering life.

"Some of the people who started that group are also part of BioBrick Foundation, a non-profit, and a company called Codon Devices. So the founders of the field are defined by the intersection, or union, of those sets, depending how you look at it.

"BioFab group is also a subset of the Codon Devices scientific advisory board. And that's a Cambridge company that does synthetic biology. We're distinct from IGEM and the BioBrick Foundation and other synthetic biology groups that are emerging. "

Church points out that "almost every new thing is a combination of two old things. This is a kind of a union of engineering design principles that might be familiar to people in large-scale integrated circuits, combining that with genetic engineering, metabolic engineering, both of which are older — decades old, not ancient — and systems biology, which itself is a combination of feedback concepts, differential equations and so forth — those could be incorporated as well. There's also some bringing together of the chemistry and automation to make DNA — large highly accurate pieces of DNA — combining in concepts of laboratory evolution, which is relatively new. These things all meet together — kind of all these streams flowing together suddenly, all at once, into synthetic biology. Enough old things brought together into a new package that it consitutes an invention, a new field."

Unlike typical labs, a BioFab "Lab" can make a copy of itself. "Once you have a really great engineered biology system, you can make as many copies of it as you want: you could scale it up… (it does it itself; it's self-assembling). It's a dream of mechanical, electrical, and chemical Fab Labs — if they ever made, say, a milling machine that could make a copy of itself. That would be great. Then they'd have a self-replicating machine; that would be a milestone."

There are inevitable questions surrounding Church and his colleagues about "playing God" and there are also concerns about the kinds of bio-terror, lab accidents, and Frankenstein-like creations that have informed the writings of such thinkers as Bill Joy and Lord (Martin) Rees. These concerns were addressed by researchers in the field last month at SythenticBiology2.0, the second annual conference in this new field, which was convened at US-Berkeley. According to their Web site, "the SB2.0 community is developing a written statement describing some principles for advancing this new field in a safe and effective way, based on the third day of discussions and here."

The Journal Science Interviews J. Craig Venter About the first "Synthetic Cell"

artificial life breakthrough

BBCNews | Scientists in the US have succeeded in developing the first synthetic living cell.

The researchers constructed a bacterium's "genetic software" and transplanted it into a host cell.

The resulting microbe then looked and behaved like the species "dictated" by the synthetic DNA.

The advance, published in Science, has been hailed as a scientific landmark, but critics say there are dangers posed by synthetic organisms.

The researchers hope eventually to design bacterial cells that will produce medicines and fuels and even absorb greenhouse gases.

Craig Venter defends the synthetic living cell

The team was led by Dr Craig Venter of the J Craig Venter Institute (JCVI) in Maryland and California.

He and his colleagues had previously made a synthetic bacterial genome, and transplanted the genome of one bacterium into another.

Now, the scientists have put both methods together, to create what they call a "synthetic cell", although only its genome is truly synthetic.

Dr Venter likened the advance to making new software for the cell. Fist tap Nana.
