Scientists discover stem cell origin of neck and shoulders

... animals. They found that it appears to survive in modern vertebrates as the scapular spine. Dr Koentges commented, "Now that we have identified these key players in forming the neck and the shoulders we can start looking for the genes that are on in these stem cells and which are ultimately responsible fo...

Space matters: Estimating species diversity in the fossil record

...raphic sampling influences diversity counts in the modern landscape, the species-area effect strongly influences counts in the fossil record. Taking this into account will alter historical estimates of species distributions and extinction. Barnosky et al. used mapping and imaging systems that generate dire...

Investigating 'brain shrinkage' in alcoholics

...m autopsies on alcoholic subjects. Scientists used modern molecular techniques to study the control mechanisms (genes) and building blocks (proteins) of the main component of white matter ?the myelin. They found that the expression of genes that control the manufacture of structural proteins of the myelin w...

Analysis of flower genes reveals the fate of an ancient gene duplication

...over a hundred million years ago in an ancestor of modern plants. The work is reported in Current Biology by a team led by Brendan Davies of the University of Leeds, England. Gene duplication--a relatively uncommon event in which a single copy of a gene is transformed into two separate copies--is thought t...

Beauty queens urge girls not to sacrifice their bones

... appealed to girls and young women to realize that modern ideas of "beauty" can damage their bones and lead to osteoporosis later in life. The women, from Australia, Austria, Panama, Thailand, Turkey and Venezuela, were speaking at "IOF Beauties and the Bones", an event organized by International Osteoporo...

'Sinkers' provide missing piece in deep-sea puzzle

One of the biggest questions in modern oceanography is how animals in the deep sea get enough to eat. Marine biologists at the Monterey Bay Aquarium Research Institute (MBARI) recently published a paper that helps answer this question, at least for animals that live on the deep seafloor o...

Virginia Tech, Nanjing Institute researchers discover half-billion year-old fossils

...i, lichen, or algae do today." The resemblance to modern fungi, lichen, or algae may stop at the seemingly similar life position on ocean floor. "In fact, the morphology of the new fossils is unlike any living macroscopic life," Xiao said, "and at this time it is still uncertain how the Ediacara fossils fr...

Researchers in Xu's group first tried to adapt the P element for use in mice and to improve the efficiency of the Sleeping Beauty transposon system. When those efforts failed, they chose piggyBac because its enzyme looked and act...
