Asteroids have hit the earth many times, causing major extinctions and leaving tell-tale craters?and it turns out there are gigantic craters on Mars as well. Perhaps they wiped out life there as well?

A huge gash that has been discovered on Mars has long proven is the largest known crater in our solar system?so big, that it reshaped the planet by blasting away much of the planet?s crust in the area where it hit over 4 billion years ago.

In New Scientist, David Shiga reports that this conclusion goes along with “other evidence that numerous large projectiles were careening through the inner solar system at this time, such as the Mars-sized planet that walloped the primordial Earth and formed our Moon, yet left no trace on Earth.”

In her new diary, Anne Strieber writes: “The comedian George Carlin died recently and in a ‘funny’ way, he’s been an important part of my life for a long time?kind of ‘haunting’ it with laughter.”

In the US, bovine growth hormone has been used to increase milk yields for 15 years, and many consumers are starting to reject hormone-treated milk in favor of organic. But dairy farmers point out that when cows make more milk, fewer cows are needed, thus reducing a major impact on global warming.

Researchers have discovered that, compared to a non-supplemented population, giving rbST to one million cows would enable the same amount of milk to be produced using 157,000 fewer cows. The nutrient savings would be 491,000 metric tons of corn, 158,000 metric tons of soybeans, and total feedstuffs would be reduced by 2,300,000 metric tons. Producers could reduce cropland use by 219,000 hectares and reduce 2.3 million tons of soil erosion annually.

A century ago, an event in far-off Siberia gave us a wake-up call. That explosive event over remote Tunguska is generally viewed by scientists as a large space rock that pierced through the atmosphere of Siberia, then detonated to flatten some 2,000 square kilometers of trees. Could modern technology stop such an event from happening today?perhaps in a crowded city?
