David Brooks argues in his latest New York Times column that people should let cell phones, media players and personal computers do our thinking for us.

Such devices, Brooks says, tongue-in-cheek, can lighten our cognitive loads, by cultivating our media tastes for us.

Internet services such as Google can also fill the gaps in the memories of both the young and old, which have already been compromised by technology.

By manufacturing human skin cells using a printer similar to an inkjet, scientists have taken a significant first step toward generating new skin. The process, which could revolutionize the treatment of major skin wounds, could be ready for clinical trials in five years.

…Scientists expect to eventually build commercial skin printers for hospital use. Doctors would take cells from a patient’s body, multiply them, and suspend them in a nutrient-rich liquid similar to ink. A technician would enter measurements of a patient’s wound into a computer and feed the suspended cells into the printer.

The cells would then be seeded on a plastic tissue scaffold, which provides shape and stability to the new piece of skin as it develops. The scaffold would also anchor the perfectly shaped piece of skin over the wound, once applied, keeping the graft in place until it takes hold.

By mimicking structures found in seashells, scientists have created a transparent plastic that is as strong as steel.

Humans could marry robots within the century. And consummate those vows.

“My forecast is that around 2050, the state of Massachusetts will be the first jurisdiction to legalize marriages with robots,” artificial intelligence researcher David Levy at the University of Maastricht in the Netherlands told LiveScience. Levy recently completed his Ph.D. work on the subject of human-robot relationships, covering many of the privileges and practices that generally come with marriage as well as outside of it.

At first, sex with robots might be considered geeky, “but once you have a story like ‘I had sex with a robot, and it was great!’ appear someplace like Cosmo magazine, I’d expect many people to jump on the bandwagon,” Levy said.

The idea of romance between humanity and our artistic and/or mechanical creations dates back to ancient times, with the Greek myth of the sculptor Pygmalion falling in love with the ivory statue he made named Galatea, to which the goddess Venus eventually granted life.

This notion persists in modern times. Not only has science fiction explored this idea, but 40 years ago, scientists noticed that students at times became unusually attracted to ELIZA, a computer program designed to ask questions and mimic a psychotherapist.

“There’s a trend of robots becoming more human-like in appearance and coming more in contact with humans,” Levy said. “At first robots were used impersonally, in factories where they helped build automobiles, for instance. Then they were used in offices to deliver mail, or to show visitors around museums, or in homes as vacuum cleaners, such as with the Roomba. Now you have robot toys, like Sony’s Aibo robot dog, or Tickle Me Elmos, or digital pets like Tamagotchis.”

In his thesis, “Intimate Relationships with Artificial Partners,” Levy conjectures that robots will become so human-like in appearance, function and personality that many people will fall in love with them, have sex with them and even marry them.

“It may sound a little weird, but it isn’t,” Levy said. “Love and sex with robots are inevitable.”

When your favorite gadget of the future breaks, you might select a replacement model online, download its design file and make a true 3-D replacement on your home printer.

Thanks to falling prices and wider application of an industrial technology called 3-D printing (among other things), this option might be a reality for consumers in a few years.

Instead of stamping or casting to create objects using tools, dies and forms that were laboriously created for the task, each object is basically printed — built thin layer by thin layer directly from a computer-aided design, or CAD, file using various high-accuracy deposition methods.

Sintering, for instance, deposits layers of fine particles that are heated until they bind to adjacent particles. Stereo-lithography, meanwhile, uses a laser to harden a layer of an object on the surface of a pool of special resin. The object is then lowered slightly, and the next layer is created. Altogether, 3-D printing technologies can create things out of plastics, metal and ceramics, and some methods can add photo-realistic coloring.

More importantly, prices for 3-D printing machines have been falling rapidly, reaching $20,000, and the day is foreseeable when they will fall below $1,000 and become home appliances, says Phil Anderson of the School of Theoretical and Applied Science at Ramapo College in New Jersey.

The results, he warned, could be economically “disruptive.”

“If you can make what you need in your own home quickly, then manufacturers become designers, with no need for factories, warehouses or shipping…”

Craig Venter, the controversial DNA researcher involved in the race to decipher the human genetic code, has built a synthetic chromosome out of laboratory chemicals and is poised to announce the creation of the first new artificial life form on Earth.

The announcement, which is expected within weeks and could come as early as Monday at the annual meeting of his scientific institute in San Diego, California, will herald a giant leap forward in the development of designer genomes. It is certain to provoke heated debate about the ethics of creating new species and could unlock the door to new energy sources and techniques to combat global warming.

Mr Venter told the Guardian he thought this landmark would be “a very important philosophical step in the history of our species. We are going from reading our genetic code to the ability to write it. That gives us the hypothetical ability to do things never contemplated before”.

The Guardian can reveal that a team of 20 top scientists assembled by Mr Venter, led by the Nobel laureate Hamilton Smith, has already constructed a synthetic chromosome, a feat of virtuoso bio-engineering never previously achieved. Using lab-made chemicals, they have painstakingly stitched together a chromosome that is 381 genes long and contains 580,000 base pairs of genetic code.

The DNA sequence is based on the bacterium Mycoplasma genitalium which the team pared down to the bare essentials needed to support life, removing a fifth of its genetic make-up. The wholly synthetically reconstructed chromosome, which the team have christened Mycoplasma laboratorium, has been watermarked with inks for easy recognition.

It is then transplanted into a living bacterial cell and in the final stage of the process it is expected to take control of the cell and in effect become a new life form. The team of scientists has already successfully transplanted the genome of one type of bacterium into the cell of another, effectively changing the cell’s species. Mr Venter said he was “100% confident” the same technique would work for the artificially created chromosome.

The new life form will depend for its ability to replicate itself and metabolise on the molecular machinery of the cell into which it has been injected, and in that sense it will not be a wholly synthetic life form. However, its DNA will be artificial, and it is the DNA that controls the cell and is credited with being the building block of life.

They’re already predicting, mathematically, what you’ll want to watch, what you’ll want to wear, and who you’ll want to vote for. Obviously, the next step is for computers to read your mind — and that’s just what they’re working toward at Tufts University in Boston.

Scientists have converted an organism into an entirely different species by performing the world’s first genome transplant, a breakthrough that paves the way for the creation of synthetic forms of life.

…The group’s study, details of which were revealed in the US journal Science yesterday, proves it is possible to transplant a complete set of genetic instructions into an organism, in effect turning it into the same species the DNA was taken from.

…In the experiment, researchers extracted the whole genetic code from a simple bacterium, Mycoplasma mycoides. They squirted the DNA into a test tube containing a related species, Mycoplasma capricolum. They found that some of the bacteria absorbed the new genome and ditched their own. These microbes grew and behaved exactly like the donor.
