As ESR puts it:

Beyond the edge of the solar system, something has gradually dragged two of America's oldest space probes — Pioneer 10 and Pioneer 11 — a quarter-million miles off course. Astrophysicists have struggled 15 years in vain to identify the infinitesimal force at play. The Pioneer anomaly, as it is called, throws a monkey wrench into celestial mechanics.
Slava Turyshev may have found the answer in NASA's trash. Reconstructing decades of discarded spacecraft data, the Russian-born astrophysicist and the private space enthusiasts helping him say they believe they are on the verge of solving a mystery of time and gravity that has perplexed a generation of physicists and might have confounded Newton and Einstein.

Then, at JPL in 2002, he discovered 400 computer tapes of Pioneer data gathering dust under a stairwell. In 2005, he intercepted 70 filing cabinets of Pioneer engineering data on their way to the junk heap at the NASA Ames Research Center, at Moffett Field, Calif. The computer files held all of the Pioneer mission data, but they were unreadable.
With no formal NASA funding, almost 6,000 members of The Planetary Society, a space-exploration advocacy group based in Pasadena, Calif., donated $220,000 to translate the antiquated data into a digital format that a modern computer can read.

The eastern Atlantic Ocean, for example, is often characterized by large phytoplankton blooms; the source of iron is the aeolian dust that blows off the coast of Africa from the Sahara desert.
Replete with nitrogen, phosphorus and iron — amongst other nutrients — the dust essentially acts as a fertilizer to stimulate the production of large blooms.

These results quantify the time-space tradeoff of garbage collection: with five times as much memory, an Appel-style generational garbage collector with a non-copying mature space matches the performance of explicit memory management. With only three times as much memory, it runs on average 17% slower than explicit memory management. However, with only twice as much memory, garbage collection degrades performance by nearly 70%. When physical memory is scarce, paging causes garbage collection to run an order of magnitude slower than explicit memory management. [emphasis added]
