| LARGE DIAMONDS MADE FROM GAS ARE THE HARDEST YET |
| Washington, D.C. Producing a material that is harder than natural diamond has been a goal of materials science for decades. Now a group* headed by scientists at the Carnegie Institution's Geophysical Laboratory in Washington, D.C., has produced gem-sized diamonds that are harder than any other crystals. Further, the researchers grew these diamonds directly from a gas mixture at a rate that is up to 100 times faster than other methods used to date. |

| MELTING CRUST MAKES RICH MINERAL DEPOSITS: GEOLOGIST |
| A University of Toronto study suggests why giant gold and copper deposits are found at some volcanoes but not others, a finding that could point prospectors to large deposits of these and other valuable metals. |

| BACTERIA POINT THE WAY TO GOLD DEPOSITS |
| Can bacteria help find gold? A pilot survey of 11 soil profiles across gold mining regions in the Peoples Republic of China indicates that elevated spore counts of Bacillus cereus, a common soil bacterium, were detected in areas adjacent to underlying gold deposits. |
