Ernst Mayr's theory illustrated in genetic epidemiology studies

...int of view." Templeton said that the Fisher camp views major and minor genes as if they are the properties of the single gene itself. His, Wright's and Mayr's view is that major and minor are properties of an interactive genetic system, and, depending on the frequencies of the interacting factors, some ...

Dr. Pauly will be presenting his views as part of a symposium on international scientific cooperation for the transition to sustainable development at the annual meeting of the American Association for the Advancement of Science February 17 in St. Louis. Dr. Pauly is the principal invest...

Study reveals classic symbiotic relationship between ants, bacteria

...ample of mutually beneficial symbiosis, and Currie views it as a model system with the potential to shed light on the way other organisms interact. Although the ants and their fungus gardens had been closely studied for dozens of years, Currie was the first scientist to identify the crucial role of bacter...

Creating a window on 'oceans in motion'

...ing and interpretation. "Contrary to 19th-century views that the oceans were essentially infinite, the 20th century showed us that human activities can transform ocean ecosystems on a global scale and the 21st century, so far, leaves little doubt that problems will compound as climate change occurs," says...

Researcher gives hard thoughts on soft inheritance

...gave rise to birds with long legs. Neo-Lamarckian views of evolutionary change stress the importance of the environment in altering inheritance. "When most biologists hear the name Lamarck or the term soft inheritance, the reaction is, 'Oh my God, here we go again'," Richards says. "But from a mol...

Because the success of wetland conservation ultimately comes down to individual wetland managers, the GlobWetland products and services are user-oriented and based on specific re...

The first tree genome is published: Poplar holds promise as renewable bioenergy resource

...er this year DOE published a study summarizing the views of over fifty leading scientists in the field of biofuels research that expressed optimism about the prospects for finding cost-effective methods to produce fuels such as ethanol from cellulose in the not-too-distant future (Breaking the Biological B...

Nanoscale microscope sheds first light on gene repair

...perspective," Greenspan said. "Should the authors' views prove to be basically correct, the study would offer the prospect of enhancing our understanding of the structural requirements for molecules used by the adaptive immune response to recognize and counter components of invading microbes. If so, it wou...

MIT bioengineer advances survival, promise of adult stem cells

... "Like some other scientists I know, my personal views about creating human ES cell lines changed when confronted with the reality of doing so from my own embryos. After this experience, I was not comfortable conducting human ES cell research myself, and I have a better understanding of why some scienti...

Satellites shed light on global warming

Row over study puts Korea's scientific community under scrutiny again

...ves little doubt about how seriously the CHA group views the potential of the incident to damage its bid to inherit Hwang's crown, says Gornall. Before his fall from grace, Professor Hwang received the bulk of Korean government funding in stem cell research. But, in November last year, CHA Medical Group an...

Invasion of the island bats

These views suffered a severe blow recently when evolutionary studies of birds of the South Pacific and Caribbean lizards uncovered at least three separate cases of island-to-continent colonization. Then again, these few instances could be interpreted as the exc...

Better insight into brain anatomical structures

..."With this agent, we are able to get high-contrast views of the anatomical details of live mouse brain." The researchers hope that their new contrast agent will allow better research and diagnosis of brain diseases involving the CNS (central nervous system), such as Alzheimer's disease, Parkinson's disease...

New findings challenge established views on human genome

...ific community will need to rethink some long-held views about what genes are and what they do, as well as how the genome’s functional elements have evolved. This could have significant implications for efforts to identify the DNA sequences involved in many human diseases.” The completion of the Human ...
