Prehistoric aesthetics explains snail biogeography puzzle
09-18-2007 · EurekAlert!The answer to a mystery that long has puzzled biologists may lie in prehistoric Polynesians' penchant for pretty white shells, a research team headed by University of Michigan mollusk expert Diarmaid Ó Foighil has found.

- A study proposes a new universal rule to explain the equilibrium of plant populations
09-18-2007 · EurekAlert!
A study financed by the BBVA Foundation and conducted by scientists Carlos Duarte, Nuria Agustì and Nuria Marbà from the Mediterranean Institute for Advanced Studies (CSIC - University of the Balearic Islands) has allowed the first-time formulation of a universal rule that explains the equilibrium of plant communities, showing how plants assure the survival of their species whether their lives last a day or are prolonged over centuries.

- Study explains why patients with OSA are at higher risk for cardiovascular disease
06-01-2007 · EurekAlert!
Researchers have found that patients with obstructive sleep apnea have higher levels of a type of dead cells (apoptotic cells) from the lining (endothelium) of their blood vessels circulating in their bloodstream than people who do not have OSA. The finding may help explain why those with OSA are at higher risk for cardiovascular disease.

- Genetic mutation explains form of brittle bone disease
10-19-2006 · EurekAlert!
A newly identified gene mutation helps explain a subset of cases of osteogenesis imperfecta, or brittle bone disease, whose origin had until now remained mysterious. Identifying the new mutation is important because children with the disorder, whose bones break easily, are sometimes mistaken as victims of child abuse -- particularly those who do not carry the genetic mutation known to cause most cases of brittle bone disease.

- New theory explains enhanced superconductivity in nanowires
10-18-2006 · EurekAlert!
Superconducting wires are used in magnetic resonance imaging machines. Eventually, ultra-narrow superconducting wires might be used in power lines designed to carry electrical energy long distances with little loss. Now, researchers at the University of Illinois at Urbana-Champaign not only have discovered an unusual phenomenon in which ultra-narrow wires show enhanced superconductivity when exposed to strong magnetic fields, they also have developed a theory to explain it.

- Science study explains polio's tenacious grip in India
11-16-2006 · EurekAlert!
New research helps explain polio's persistence in India despite massive immunization efforts and offers hope for the campaign to stamp out the virus once and for all. The study, whose authors include some of the experts heading the global polio eradication effort, appears in the November 17 issue of the journal Science, published by AAAS, the nonprofit science society.

- 'Wingman' -- how buddies help alpha males get the girl
03-05-2007 · EurekAlert!
Cooperative behavior is a classic puzzle in evolutionary biology. Some cooperation occurs in close-knit family groups and helping kin with similar genes explains apparently selfless behavior. But lance-tailed manakin males cooperate in spectacular courtship displays with unrelated partners. When the dance is over only the dominant male gets the chance to mate. The "wingman" apprentice however benefits by learning how to do a successful dance.

- New particle explains odd behavior in cuprate superconductors
07-17-2007 · EurekAlert!
New fundamental particles aren’t found only at Fermilab and at other particle accelerators. They also can be found hiding in plain pieces of ceramic, scientists at the University of Illinois report.The newly formulated particle is a boson and has a charge of 2e, but does not consist of two electrons, the scientists say. The particle arises from the strong, repulsive interactions between electrons, and provides another piece of the high-temperature superconductivity puzzle.

- Researchers move 2 steps closer to understanding genetic underpinnings of autism
01-10-2008 · EurekAlert!
Today's issue of the American Journal of Human Genetics, describes what might be a corner piece of the autism puzzle -- the identification and subsequent validation of a gene linked to the development of autism by three separate groups of scientists. An accompanying commentary by Dr. Dietrich Stephan, Director of the Neurogenomics Division at the Translational Genomics Research Institute, further explains the findings.
