May, 1997
'Missing link' between birds and dinosaurs (Nature Science Updates 5/29/97)
"A 'missing link' between birds and dinosaurs has been found in 90-million-year-old rocks in southern Argentina. Two-metre-long Unenlagia comahuensis was a small, leggy, running dinosaur, possibly similar in shape to the famously ferocious carnivore Velociraptor."

Scientists Find Possible New Human Species (Reuters 5/29/97)
"Scientists on Thursday announced the discovery of a common ancestor of both Neanderthals and modern man, a tall and lanky being with protruding brows and heavy jaws but who otherwise looked a lot like us. Homo antecessor lived 800,000 years ago, hunting in what is now Spain in oak and beech forests for rhinoceros, elephant and other game, according to scientists who discovered the species."
More Trouble for First Extrasolar Planet (Science Now 5/29/97)

Scientists find life in nasty places (UPI 5/28/97)
"Scientists say they have been looking for life in all the wrong places _ and finding it. Researchers are reporting this week at the national meeting of the American Geophysical Union that places once thought too hot, too cold, or otherwise too horrible do show signs of life."
Carbon Clouds Greenhouse-Warming Picture (Science Now 5/27/97)

Resolving the Faint Young Sun Paradox? (InScight 5/27/97)
"It takes a while for a star to get its fusion reactor up to speed; nuclear physicists have long agreed that 4 billion years ago, the sun was only 75% as bright as it is today. This means that Earth should have been completely covered with ice for most of its history. But geological evidence shows that there was plenty of liquid water as far back as about 4 billion years ago. So, what happened?"
Galileo Returns New Insights Into Callisto and Europa (JPL/NASA Press Release 5/23/97)
"Jupiter's icy moon Europa has a metallic core and layered internal structure similar to the Earth's, while the heavily cratered moon Callisto is a mixture of metallic rock and ice with no identifiable central core, according to new results from NASA's Galileo mission. In addition, recent plasma wave observations from Galileo show no evidence of a magnetic field or magnetosphere around Callisto, but do hint at the prospect of a tenuous atmosphere."
New Way to Hit the Pacific Hot Spots (Science Now 5/23/97)
"Until now, geophysicists have tried to locate hot spots by a technique that requires knowing the ages of seamounts, and that information can be hard to come by.

Researchers dispute meteorite evidence of life on Mars (CNN/AP 5/21/97)
"A new study contradicts NASA scientists' claim that a meteorite holds microscopic traces of long-ago life on Mars. According to their interpretation of pictures, the alleged traces of life were formed not by ancient organisms, but by the huge shock that sent the rock hurtling into space millions of years ago."
T-Rex, King of Dinos, Also Had Gout (Washington Post/AP 5/21/97)

The Coming Climate (Scientific American May 1997)
"Climatologists have concluded that because of the greenhouse effect and other influences, the world will grow a few degrees warmer in the next century. Yet simplistic predictions that scorching summers, more cyclones and heavier rainfall will therefore follow can be far off the mark. These experts offer a more realistic view."
NASA Joins Japan in Exploring Asteroid (Science Now 5/19/97)
