Critics quickly pointed out that Pons and Fleischmann never used a control experiment, although controls are standard scientific practices expected even of first-year chemistry students. Without a control experiment, it was impossible to tell for sure if the heat generated in the experiment came from fusion or from a previously unknown chemical reaction...
Silvera leads a team in the Lyman Labs that is using a high-pressure diamond anvil to crush together a palladium and deuterium cell. Silvera says their first test, which failed to release heat or emit subatomic particles that are expected by-products of fusion, could have failed because of accidental leaking by the liquid deuterium...
Going into the 800-meter trials, Rainey was seeded fifth according to her time. But after her heat, in which she ran a 2:04.59, Rainey had the best time entering the finals. That time also broke the Harvard record she set in April...
...October 18, 1938, in the heat of a battle to restructure the city government, the council voted unanimously to make the University a separate municipality. Although the council's request was never granted, it left a memorable legacy of the grizzled and sometimes legendary opposition between Harvard and Cambridge from which their modern discord grows...
...park, lodgepole pine and the duff from its fallen needles and branches provided most of the fuel for the fires. But nature has provided the tree with a way to make a comeback. Some lodgepole pinecones are serotinous: they open and release seeds only when activated by the heat generated by fires. In some areas surveyed by Yellowstone biologists, seed densities from such cone releases measure in the millions per acre. As a result, the ground will soon be thick with pine sprouts...
