Human-Like Ability, Categorical Perception, Found In Insects
...rsity study of insect hearing has found. Even the lowly cricket employs a sophisticated capability, called categorical perception, when its life (or love life ) is at stake. "Crickets -- and probably many other types of animals -- have found a simple way to build a system that responds quickly," said Rob...A lowly weed uses one of the same communications systems as does the humanbrain, scientists have found. In the November 12 issue of the journal Nature, Dr. Gloria Coruzzi andco-workers at New York University report that they turned up the sequence forprotein...A Mother's Love? New UD Theory Explains Why Good Insect Moms Risk Death To Save Their Only Children
...stakenly think we'rethe pinnacle of evolution, and lowly insects couldn't possibly be capable ofparenting. In fact, mothering is an ancient trait, which originated in earlyinvertebrates, then persisted in insects when they evolved." Tallamy cautions against explaining different human mothering styles by po...DNA fingerprinting reveals surprise in wine-grape family tree
...It is surprising enough that Chardonnay has such a lowly parent, but that all16 of these varieties, which include most all of the wine-grape varieties grownin northeastern France today, should have come from the same two parents isquite remarkable," Meredith said. In addition to their disparate status, Pin...New research animals earn their stripes

Now, thanks to the lowly fruit fly and a team of scientists at the University of Wisconsin-Madison and at Washington University in St. Louis, one genetic circuit that governs sexual dimorphism - the diagnostic differences between the sexes - has been found and characterized....Scientists shake up "family tree" of green plants
Apparently, the lowly fern deserves more respect. New research scheduled to appear as the journal Nature's cover story on February 1 concludes that ferns and horsetails are not -- as currently believed -- lower, transitional evolutionary grades between mosses and flo...Genetic therapies for aging will face many challenges
...nes involved in the repair of damage to DNA in the lowly bacterium, E. coli. There are certainly many more within our genome -- likely many thousands," Martin says. He theorizes that as much as 7 percent of the human genome could produce allelic variants or mutations that modulate how we age, and th...Zebrafish could become genetics 'lab rat' of choice
...ST LAFAYETTE, Ind. In the post-genomic world, the lowly zebrafish may be king. Scientists at Purdue University have developed a technique that allows zebrafish to pass genetic modifications to its offspring. The discovery will lead to researchers being able to study genes and proteins in a less expensive ...A worm is more like a human than previously thought
...rbara, Calif.) Humans have more in common with the lowly worm than previously thought, according to scientists reporting in the cover article of Molecular Cell, published today. The findings have important implications for medicine, including the study of birth defects, cancer, and tissue engineering. "O......ecting the odors that drift through its world, the lowly roundworm seems hard pressed to smell food, let alone discriminate friend from foe. But researchers have discovered a unique system of overlapping sensors that enables the creature to tell smells apart. The system seems well designed for the nerve-ch...Rat genes increase Vitamin C in plants
BLACKSBURG, Va., July 27, 2001 Genes from the lowly rat may hold the key to increasing Vitamin C in the worlds food supply. Craig Nessler, head of plant physiology, pathology, and weed science at Virginia Tech, has found that by transferring certain rat genes into lettuce, he can turn on the plants la...Science's Top Ten: nanoscale computing circuits named top scientific advance of 2001

The findings, published in the July 26 issue of Science, suggest that scientists will now be better able to tease out the details of innate immunity across a wide range of species.
