“We believe that the next step in copying will be made from digital form into physical form. It will be physical objects. Or as we decided to call them: Physibles. Data objects that are able (and feasible) to become physical. We believe that things like three dimensional printers, scanners and such are just the first step. We believe that in the nearby future you will print your spare sparts for your vehicles. You will download your sneakers within 20 years.”In an important move, bit torrent portal The Pirate Bay announces a new category of torrents called Physibles, focusing on sharing 3-D printing designs – affirmation for these 7 platforms changing the future of collaborative creation.

I can pinpoint the exact moment when I first thought I could write a novel. It was around one thirty in the afternoon of April 1, 1978. I was at Jingu Stadium that day, alone in the outfield drinking beer and watching the game. Jingu Stadium was within walking distance of my apartment at the time, and I was a fairly big Yakult Swallows fan. It was a perfectly beautiful spring day, not a cloud in the sky, with a warm breeze blowing. There weren’t any benches in the outfield seating back then, just a grassy slope. I was lying on the grass, sipping cold beer, gazing up occasionally at the sky, and leisurely enjoying the game. As usual for the Swallows, the stadium wasn’t very crowded. It was the season opener, and they were taking on the Hiroshima Carp at home. I remember that Yasuda was pitching for the Swallows. He was a short, stocky sort of pitcher with a wicked curve. He easily retired the side in the top of the first inning, and in the bottom of the inning the leadoff batter for the Swallows was Dave Hilton, a young American player new to the team. Hilton got a hit down the left field line. The crack of bat meeting ball right on the sweet spot echoed through the stadium. Hilton easily rounded first and pulled up to second. And it was at that exact moment that a thought struck me: You know what? I could try writing a novel. I still can remember the wide open sky, the feel of the new grass, the satisfying crack of the bat. Something flew down from the sky at that instant, and whatever it was, I accepted it.

Quantifying reflexivity in financial markets: towards a prediction of flash crashes
We introduce a new measure of activity of financial markets that provides a direct access to their level of endogeneity. This measure quantifies how much of price changes are due to endogenous feedback processes, as opposed to exogenous news. For this, we calibrate the self-excited conditional Poisson Hawkes model, which combines in a natural and parsimonious way exogenous influences with self-excited dynamics, to the E-mini S&P 500 futures contracts traded in the Chicago Mercantile Exchange from 1998 to 2010. We find that the level of endogeneity has increased significantly from 1998 to 2010, with only 70% in 1998 to less than 30% since 2007 of the price changes resulting from some revealed exogenous information. Analogous to nuclear plant safety concerned with avoiding “criticality”, our measure provides a direct quantification of the distance of the financial market to a critical state defined precisely as the limit of diverging trading activity in absence of any external driving.

It is commonly believed that with aging comes an inevitable decline from vitality to frailty. This includes feeling weak and often the loss of independence. These declines may have more to do with lifestyle choices, including sedentary living and poor nutrition, than the absolute potential of musculoskeletal aging. In this study, we sought to eliminate the confounding variables of sedentary living and muscle disuse, and answer the question of what really happens to our muscles as we age if we are chronically active. This study and those discussed here show that we are capable of preserving both muscle mass and strength with lifelong physical activity.
