- Medieval Islamic designs reveal breakthrough in tiled pattern-making
02-22-2007 · EurekAlert!
Medieval Islamic artisans developed a pattern-making process for designing ornate tiled surfaces that allowed them to produce sophisticated patterns not seen in the West until centuries later, a new study suggests. The findings appear in the Feb. 23 issue of the journal Science, published by AAAS, the nonprofit science society.

- Major gene study uncovers secrets of leukemia
03-07-2007 · EurekAlert!
Investigators at St. Jude Children's Research Hospital have discovered previously unsuspected mutations that contribute to the formation of pediatric acute lymphoblastic leukemia (ALL), the most common cancer in children. The discovery not only suggests novel methods for treating pediatric ALL, but also provides a roadmap for the identification of unsuspected mutations in adult cancers.

- Fossilized liquid assembly: Nanomaterials research tool
10-12-2006 · EurekAlert!
From a butterfly's iridescent wing to a gecko's sticky foot, nature derives extraordinary properties from ordinary materials like wax and keratin. Its secret is hierarchical topology -- macroscale structures assembled from microscale components of varying sizes. Borrowing a page from nature's playbook, researchers at NIST have developed a novel platform for the self-assembly of experimental hierarchical surfaces in a fluid. Their work offers diverse industries a new way to generate and measure self-assembly at the nanoscale.

- Bodily breakdown explained: How cell differentiation patterns suppress somatic evolution
12-14-2007 · EurekAlert!
Natural selection can occur at the cellular level, where it is detrimental to health. Fortunately it is normally controlled by a well-known pattern of ongoing cell differentiation in the mature tissues of animals, according to a new study published Dec. 14 in PLoS Computational Biology.

- Tears reveal some of their deepest secrets to researchers
01-19-2007 · EurekAlert!
It's no secret why we shed tears. But exactly what our tears are made of has remained a mystery to scientists. A new study sheds some light on the complex design of tears. What we think of as tears, scientists call tear film, which is made up of three distinct, microscopic layers.

- UCLA study uncovers clues for why Graves' disease attacks the eyes
03-01-2007 · EurekAlert!
UCLA researchers have uncovered new clues that may explain why Graves' disease attacks the muscle tissue behind the eyes, often causing them to bulge painfully from their sockets. The findings may deepen understanding of how the autoimmune disorder damages the body and offer a new target for treating the disfiguring disease.

- Drought sensitivity shapes species distribution patterns in tropical forests
05-14-2007 · EurekAlert!
Looking at a rainforest it's easy to see that there are hundreds of different tropical plant species that inhabit the forest. Although the patterns of plant distributions in tropical forests have been widely studied, the reasonings behind these patterns are not as well known. This study, published in Nature, explores these patterns.A contingent of researchers from around the world, including Panama, Germany, USA and Canada, have uncovered that tropical plant species distribution patterns are linked to the plant’s drought sensitivity.

- Einstein researchers use novel approach to uncover genetic components of aging
08-24-2007 · EurekAlert!
People who live to 100 or more are known to have just as many -- and sometimes even more -- harmful gene variants compared with younger people. Now, scientists at the Albert Einstein College of Medicine of Yeshiva University have discovered the secret behind this paradox: favorable "longevity" genes that protect very old people from the bad genes' harmful effects. The novel method used by the researchers could lead to new drugs to protect against age-related diseases.
