Collecting Just the Right Data: When you can’t collect all you need, new algorithm tells you which to target

July 28, 2014 2:06 pm | by Larry Hardesty, MIT | News | Comments

Much artificial-intelligence research addresses the problem of making predictions based on large data sets. An obvious example is the recommendation engines at retail sites like Amazon. But some types of data are harder to collect than online click histories — information about geological formations thousands of feet underground, for instance. And in other applications there may just not be enough time to crunch all the available data.

NASA Finds Friction from Tides Could Help Distant Earths Survive

July 15, 2014 4:28 pm | by Elizabeth Zubritsky, NASA Goddard Space Flight Center | News | Comments

As anybody who has started a campfire by rubbing sticks knows, friction generates heat. Now, computer modeling by NASA scientists shows that friction could be the key to survival for some distant Earth-sized planets traveling in dangerous orbits. The findings are consistent with observations that Earth-sized planets appear to be very common in other star systems.

Chemists Discover Boron Buckyball

July 15, 2014 11:55 am | by Brown University | News | Comments

The discovery 30 years ago of soccer-ball-shaped carbon molecules called buckyballs helped to spur an explosion of nanotechnology research. Now, there appears to be a new ball on the pitch. Researchers have shown that a cluster of 40 boron atoms forms a hollow molecular cage similar to a carbon buckyball. It’s the first experimental evidence that a boron cage structure — previously only a matter of speculation — does indeed exist.
