Bones of Crocodile-like Beasts Tell Tale of Global Warming
...ent we hadn'tseen before. Once we reached them, we realized these were fine-grain sedimentaryrocks ideal for preservation of fossils, and I bet the students we'd findfossils. Within five minutes one of my students pulled up a femur and said,"Like this?" "It was one of those rare instances where you kn...New Forest Owners Prefer Enjoying Their Land Over Working It
..."We knew there were absentee landowners, but never realized there would bethis many," said Jacobson, who conducted the survey. The 29-question survey was sent to property owners with more than 20 acresof forest land. Results showed that 64 percent of the 1,017 respondentslive away from their forests, and many...Scientists Find First Protein In Central Nervous System Junctions

"Those patients have seizures early in life, and theyextend their body and limb muscles just like our gephyrin mutants. They alsocan'...... "In the 1980s we began losing birds andplants and realized that the same thing was happening to organisms in the soil." A second factor is what Wall called "a deep, wide disciplinary schism"that has traditionally separated the scientists who classify organisms(taxonomists) from those who study ecosys...Birds Of A Feather: The Physics Of Flocks
...a sort of "error" in the material. Vicsek quickly realized a major problem with the ferromagnet analogy. Becauseheat is always present in real-world situations, each atom's magnet tends tobecome slightly misaligned with that of its neighbor. And the slightmisalignments between neighbors mean that distant m...Molecular Circuit Breaker Can Prevent Runaway Cell Growth

Theintimate physical relationship between two overlapping genes that ordinarilyrestrain cell multiplication explains why the INK4a-ARF gene pair ismissing in many h......ment led him one day to the campus pub. There, he realized that thesimilarity between 6-arm DNA branched junctions and the periodic array of flyingfish in Escher's 'Depth' might lead to the rational approach to crystallizationdescribed here.
