Researchers find origin of ‘breathable’ atmosphere half a billion years ago
Ohio State University geologists and their colleagues have uncovered evidence of when Earth may have first supported an oxygen-rich atmosphere similar to the one we breathe today.The study suggests that upheavals in the earth’s crust initiated a kind of reverse-greenhouse effect 500 million years ago that cooled the world’s oceans, spawned giant plankton blooms, and sent a burst of oxygen into the atmosphere.
Giant Red Spinel Crystal Discovered in East Africa
An enormous red spinel crystal weighing over 52 kgs may be the largest red spinel ever unearthed. A significant number of stones ranging in weights between 5 and 30 carats have already been faceted and sold for several million dollars. Mined at depth of 10 meters in a farmer’s field in Mahenge, Tanzania, the pyramid shaped crystal weighing over 52kgs was discovered by a group of miners in the alluvial deposit.

Census Of Protein Architectures Offers New View Of History Of Life
The present can tell you a lot about the past, but you need to know where to look. A new study appearing this month in Genome Research reveals that protein architectures – the three-dimensional structures of specific regions within proteins – provide an extraordinary window on the history of life.
Even Without Math, Ancients Engineered Sophisticated Machines
Move over, Archimedes. A researcher at Harvard University is finding that ancient Greek craftsmen were able to engineer sophisticated machines without necessarily understanding the mathematical theory behind their construction
