Craig Venter's Talk
Craig Venter and team make a historic announcement: they've created the first fully functioning, reproducing cell controlled by synthetic DNA. He explains how they did it and why the achievement marks the beginning of a new era for science.
About Craig Venter
In 2001, Craig Venter made headlines for sequencing the human genome. In 2003, he started mapping the ocean's biodiversity. And now, in 2010, he's created the first synthetic lifeforms.

The biologist who mapped the human genome, Dr. Craig Venter, has announced he has now created a synthetic cell aka synthetic life. The new Ventor project transferred D.N.A. built from chemicals into a cell and mitosis (cell division) occurred. The plans for the D.N.A. were taken from a natural organism so it is a little less than making a new life form with a human design such as a living tyrannosaurus with some of George Washington’s facial features, or a tiny flesh-eating mosquito, yet the premise was demonstrated that the capability exists.
Dr. Venter and company plan to manufacture synthetic life forms in order to stimulate the economy, or find health solutions. I have a few comments.
Human society has a wild element. A thief recently stole five paintings valued between 100 and 600 million dollars from the Paris Museum of Modern Art. The paintings may be eventually a hedge against the collapse of civilization. Collectors in a post-apocalyptic world might value them quite highly. The Picasso, Matisse and other paintings in the collection may in the future be more valuable than gold. The end of civilization may develop through several channels including perhaps, synthetic life forms and synthetic viruses.
The scientific effort to understand life, and all of nature is commendable, yet the knowledge gained may be quite dangerous, and better left as knowledge rather than downloaded into a compulsory use category. Life took at least several days/eras/billions of years of time literal values to develop. Human society has existed in a civilized form just about 6000 years. It is rash to just create synthetic life and use it for economic or any other purposes as if human capacity to contain technology from oil spills to nuclear radiation is fool-proof. Let’s (humanity) study synthetic life issues for 5000 years—just a fraction even of the time life has been on Earth, and then consider the question again.
The usual excuse for playing God with nature is that it has positive economic benefits. Using economics as a justification to overcome moral objections is a bad rationale. It is an amoral compulsion consistent more with primitive life than philosophically mature life forms such as human beings occasionally try to be.
There are an infinite number of solutions to social economic challenges given existing materials that do not require the creation of synthetic life forms to fully satisfy human needs on Earth. The problem with human economics are in greed, unintelligent use of resources, failure to develop ecological economic policy and no plans to develop an exo-biological containment facility in the moon for returning astronauts from Mars and for Dr. Venter’s synthetic life forms.
Synthetic life—altered D.N.A. of biological organisms, present innumerable hypothetical problems of containment of new life forms and for survival of existing species. Creation of synthetic life except for research modeling perhaps is a reckless use of new science akin to letting every kid have a tabletop fusion kit so he can make fusion-powered rockets to visit other planets—such a power would be explosive.
In this universe, the 13.7 billion year evolution of intelligent life—and perhaps more time than we know with another sort of time-space precursor of this universe including the modge panc (mind plans) of God, has brought into being a synthetic, adaptive union of mind with inanimate materials existing uncertainly with a substratum of quantum wave-particles of an uncertain deep field nature. It is truly reckless beyond reason to alter the evolving life forms of given natural species and mutate beyond recognition theoretically, the phenomenal order of being that might eventually be deeply comprehended by the beings living within it.
The creation of synthetic life forms for war and peace, sales in Jiffy-Marts and marketed on Wall-Street is an epiphenomenal bit of idiocy that would make a kaleidoscope of living organisms for immediate, proximal economic value.
Perhaps some scientific sentiment exists to create a Frankenstein Supremacy Species better than science fiction has ever conceived before. Maybe Sigourney Weaver’s challenges in the Alien movie series are a little shopworn now and require spicing up with flesh eating synthetic life hungering for politicians in the District of Columbia (I don’t intend to inadvertently give support Dr. Venter’s plan), yet what needs to be done is passage of a law by congress directly making creation of synthetic life forms illegal in the United States of America.
The creation of synthetic life is a form of biological war upon all naturally evolved species that should be outlawed. With computer modeling of D.N.A. elements it may be possible to learn much from about the synthetic, hypothetical form of various creatures without making any. Slavery, cannibalism and other bad human practices required thousands of years to eliminate from human society, now is not the time-nor ever should it be, to dump creation of a Pandora’s box of new biological ways of exploiting life, endangering life, and dehumanizing anything so that the corrupt and unconscionable may have advantage socially over others. Such practices deserve war upon them rather than support. Breaking the boundaries of reason, justice and civility should be discouraged rather than tossed into the stew pot of corporate progress.
When the civilization collapses and the economic consumption patterns of today are history, we don’t want a plethora of synthetic life forms running loose to serve remaining humans up for dinner because there are no PhDs in biology around to war upon them.

Blackfriars Street Bridge
From Wikipedia, the free encyclopedia
Coordinates: 42°59′14″N 81°14′47″W / 42.98714°N 81.246268°W / 42.98714; -81.246268
The Blackfriars Street Bridge in London, Ontario, Canada is a wrought iron, through, bowstring truss or tied arch bridge, placed across the North Thames River in 1875 and still carrying frequent vehicular and pedestrian traffic. At 216 feet (65.8 meters) it is the longest working span of that kind in North America.[1]

Engineering
According to bridge historian Nathan Holth,Bowstring bridges are one of the rarest types of truss bridges, and most date in the 1870s. They fell out of favor due to the limited weight they could support. Any bowstring truss bridge that survives today is a miracle. Truss bridges are always intricate structures, but bowstring trusses are even more so. There [are] lattice, v-lacing, and members all over. This large amount of complexity is balanced by the simple, graceful appearance of the arched top chord. The result is a bridge with incomparable beauty and appeal. Among the rarest and oldest bridges in Canada is this breathtaking iron bowstring truss. Keystone Columns form the top chord. A sidewalk on the south side appears to be original. The bridge has undergone extensive repairs and modifications. Most notably, the top chord has had plates of steel welded to the top of the column. Numerous rods and bars have been welded onto many of the vertical and diagonal members as well. A couple of added bars of steel run lengthwise through the middle of the truss. These modifications have affected the historic integrity of the bridge, but have no doubt helped keep it standing over 130 years. The original lattice guardrails remain on the sidewalk, albeit with a metal pole welded above them. [2]
The deck surface (see illus. gallery below) is presently of renewable planking: a double file of approximately one-thousand, five hundred eight-foot two-by-fours each, on edge, upon a framework of nine longitudinally laid stringers of one-foot iron I-beams, topped with bolted-on wooden cladding, whose ends rest on the two abutments. Attached beneath these are fifteen transverse floor-beams, from which vertical lattice pillars, under tension, translate the live thrusts of traffic to the bowed upper chord, which transfers this back as tension along the bottom-chord "string" of the bow. This bottom chord consists of two sets of four 10 cm x 3 cm wrought-iron eyebars, running along, outside, both sides of the deck. Although originally two-lane, due to the weight and frequency of modern traffic, the Blackfriars is at present two-way but single-lane. Because of damage to the wooden deck surface and to the iron structure, there is recurrent consideration of closing it to four-wheeled vehicles.
The Blackfriars Street Bridge (BSB) was manufactured by the Wrought Iron Bridge Company (WIBC) of Canton, Ohio, although erected by local London contractor Isaac Crouse. There is evidence for its being prototypical for a revised design by WIBC, incorporating a double-panel web.[3] The BSB is the successor to a series of fixed, wooden structures at the site since 1831, which were damaged mainly by spring "freshets" of the river.[4] It has been designated a historic structure under Part IV of the Ontario Heritage Act. The BSB is the northernmost and oldest of a company of eight bridges of different ages, constructions and uses,[5] surrounding the confluence of the North Thames and Thames rivers, which fixes the historic center of London. The Bridge is sited at the east end of a short Blackfriars Street,[6] which turns sharply south and up a slight grade, as the downtown Ridout Street, upon crossing it. To the BSB's west is the lower ground of the previous town of Petersville, protected by an extensive dike embankment, due to a history of flooding; to its east a terrace rises above the North Thames River to central London.[7] The river there is bordered on both sides by extensive bicycle and walking paths, and the Bridge is well framed by a variety of second-growth trees.
Much of the "beauty and appeal" of the BSB is its appearing to float, from many profile views provided on both banks of the gently winding river, up and downstream. That is owing not only to its strung-bow shape but also to its light placement, at its very tips, upon modest granite abutments—a feature rare among more modern tied-arch bridges. These abutments bear the passive vertical load of the open structure itself. However, the varying ‘live’ thrust forces of traffic downward on its deck are translated by the bowed chord above into horizontal tensions along the longitudinal iron eyebars of the 'string' or bottom chord running parallel to the deck.
The Blackfriars Street Bridge has figured in various artistic works, visual and literary, including a series of stained glass windows by Ted Goodden. Nathan Holth praises the City of London and the Province of Ontario for maintaining its old iron bridges. Regarding the nearby, larger pony-truss Kensington Bridge he praises the City for "keeping the Thames River looking wild and natural," even near its center, with the look of "a rural bridge in an urban environment, which further enhances the beauty of the bridge",[8] a remark that would apply as well to the Blackfriars. With recent improvement of the rivers, wild nature seems to confirm the point.[9] (See, below, resident Great blue heron in winter.)

Thanks to you, 13,000 square kilometers of Boreal Habitat will be protected! Dear john, I love a good reason to celebrate, and we’re still celebrating Canada’s commitment to establish this country’s next national park -- a National Park Reserve in the Mealy Mountains of Labrador! I want to thank you for your part in helping us achieve this success. By supporting Nature Canada you helped give us the voice we needed to work with local communities, First Nations leaders, and governments at all levels to make this dream a reality. We have been working towards this day for over 15 years, and it is historic achievements like these that illustrate how important ongoing support from people like you really is in protecting habitats and wildlife. The permanent protection of such a large area of boreal forest inside Mealy Mountains National Park Reserve ensures at-risk species like the woodland caribou and the harlequin duck have the habitat they need to survive. The park also serves as an anchor of protected space along the Atlantic Flyway, an important breeding ground and migration route for many arctic bird species. I invite you to view this special photo slide show featuring some of the species that will now be protected, thanks to you. Sincerely, Ian Davidson, Executive Director Nature Canada | Help Achieve More Successes Like Mealy Mountains With your support, we can restore more critical habitat, like Mealy Mountains, and push for greater protection of endangered species. Working together, we do make an impact! |
