The New York Time reported Space Exploration Technologies of Hawthorne, Calif. — SpaceX, for short — launched its Falcon 9 rocket on schedule at 8:35 p.m. Eastern time from Cape Canaveral, Fla.

The Wall Street Journal reported, “trouble-free countdown followed by liftoff at 8:35 p.m. ET, precisely as scheduled.”

Maj. Gen. Charles F. Bolden Jr., the NASA administrator said, “It actually marks the beginning of true commercial spaceflight to take cargo to the International Space Station for us.”

This is a milestone in the relationship between public and private enterprise. The handoff of what public enterprise, NACA/NASA, pioneered, developed and brought to maturity, to private enterprises capable of lowering the costs of space travel with ambitions to do more than stay in low earth orbit.

Congratulations, to Elon Musk, who believed it was possible, and went ahead and proved all the nay sayers wrong. This is an example of how one man’s vision and tenacity has changed the way we perceive the world. Congratulations!

At the halfway point to a climate gamble, 50 contributor ideas give just a taste of the creativity and innovation available to us

“One or other of us will have to go,” Oscar Wilde is supposed to have said on his deathbed to the hated wallpaper in his room. The perilous acceleration of Arctic ice loss, and the imminent threat of irreversible climate change poses a similar ultimatum to the economic system that is pushing us over the brink. For society’s sake I hope this time we redecorate.

Fortunately, many people are queuing up to propose better designs, rather than just cursing the interiors, as you can read about here.

Monday 1 October marks the halfway point in a 100-month countdown to a game of climate roulette.

In this post we will look at the last three types of engines. Can these engine technologies be debunked?

Start with the boring stuff. Nuclear/plasma engines. For more information look up Franklin Chang-Diaz’s Variable Specific Impulse Magnetoplasma Rocket (VASIMR). Real. Cannot be debunked.

Now for the more interesting stuff. The second is Pulse Detonation Engines (PDE). This type of engine uses detonation waves to combust fuel and oxidizer mixture. “The engine is pulsed because the mixture must be renewed in the combustion chamber between each detonation wave initiated by an ignition source.” Theoretically this type of engine is capable of speeds from subsonic to Mach 5.

On January 28 2011, three days into the fierce protests that would eventually oust the Egyptian president Hosni Mubarak, a Twitter user called Farrah posted a link to a picture that supposedly showed an armed man as he ran on a “rooftop during clashes between police and protesters in Suez”. I say supposedly, because both the tweet and the picture it linked to no longer exist. Instead they have been replaced with error messages that claim the message – and its contents – “doesn’t exist”.

Few things are more explicitly ephemeral than a Tweet. Yet it’s precisely this kind of ephemeral communication – a comment, a status update, sharing or disseminating a piece of media – that lies at the heart of much of modern history as it unfolds. It’s also a vital contemporary historical record that, unless we’re careful, we risk losing almost before we’ve been able to gauge its importance.

Consider a study published this September by Hany SalahEldeen and Michael L Nelson, two computer scientists at Old Dominion University. Snappily titled “Losing My Revolution: How Many Resources Shared on Social Media Have Been Lost?”, the paper took six seminal news events from the last few years – the H1N1 virus outbreak, Michael Jackson’s death, the Iranian elections and protests, Barack Obama’s Nobel Peace Prize, the Egyptian revolution, and the Syrian uprising – and established a representative sample of tweets from Twitter’s entire corpus discussing each event specifically.

It then analysed the resources being linked to by these tweets, and whether these resources were still accessible, had been preserved in a digital archive, or had ceased to exist. The findings were striking: one year after an event, on average, about 11% of the online content referenced by social media had been lost and just 20% archived. What’s equally striking, moreover, is the steady continuation of this trend over time. After two and a half years, 27% had been lost and 41% archived.

I have been meaning to read a book coming out soon called Regenesis: How Synthetic Biology Will Reinvent Nature and Ourselves. It’s written by Harvard biologist George Church and science writer Ed Regis. Church is doing stunning work on a number of fronts, from creating synthetic microbes to sequencing human genomes, so I definitely am interested in what he has to say. I don’t know how many other people will be, so I have no idea how well the book will do. But in a tour de force of biochemical publishing, he has created 70 billion copies. Instead of paper and ink, or pdf’s and pixels, he’s used DNA.

Much as pdf’s are built on a digital system of 1s and 0s, DNA is a string of nucleotides, which can be one of four different types. Church and his colleagues turned his whole book–including illustrations–into a 5.27 MB file–which they then translated into a sequence of DNA. They stored the DNA on a chip and then sequenced it to read the text. The book is broken up into little chunks of DNA, each of which has a portion of the book itself as well as an address to indicate where it should go. They recovered the book with only 10 wrong bits out of 5.27 million. Using standard DNA-copying methods, they duplicated the DNA into 70 billion copies.

Scientists have stored little pieces of information in DNA before, but Church’s book is about 1,000 times bigger. I doubt anyone would buy a DNA edition of Regenesis on Amazon, since they’d need some expensive equipment and a lot of time to translate it into a format our brains can comprehend. But the costs are crashing, and DNA is a far more stable medium than that hard drive on your desk that you’re waiting to die. In fact, Regenesis could endure for centuries in its genetic form. Perhaps librarians of the future will need to get a degree in biology…

One question that fascinated me in the last two years is, can we ever use data to control systems? Could we go as far as, not only describe and quantify and mathematically formulate and perhaps predict the behavior of a system, but could you use this knowledge to be able to control a complex system, to control a social system, to control an economic system?

We always lived in a connected world, except we were not so much aware of it. We were aware of it down the line, that we’re not independent from our environment, that we’re not independent of the people around us. We are not independent of the many economic and other forces. But for decades we never perceived connectedness as being quantifiable, as being something that we can describe, that we can measure, that we have ways of quantifying the process. That has changed drastically in the last decade, at many, many different levels.

Earth is a hostile place — and that’s even before one starts attending school. Even when life first sparked into being, it had to evolve defenses to deal with a number of toxins, such as damaging ultraviolet light, then there were toxic elements ranging from iron to oxygen to overcome, later, there was DDT and other toxic chemicals and of course, there are all those dreaded cancers.

In Evolution In A Toxic World: How Life Responds To Chemical Threats [Island Press; 2012: Guardian Bookshop; Amazon UK;Amazon US], environmental toxicologist Emily Monosson outlines three billion years of evolution designed to withstand the hardships of living on this deadly planet, giving rise to processes ranging from excretion, transformation or stowing harmful substances. The subtitle erroneously suggests these toxins are only chemical in nature, but the author actually discusses more than this one subclass of toxins.

The method that arose to deal with these toxins is a plethora of specialised, targeted proteins — enzymes that capture toxins and repair their damages. By following the origin and progression of these shared enzymes that evolved to deal with specific toxins, the author traces their history from the first bacteria-like organisms to modern humans. Comparing the new field evolutionary toxicology to biomedical research, Dr Monosson notes: “In light of evolution, biomedical researchers are now asking questions that might seem antithetical to medicine”.
