New tumour markers -- 'Spot the differences'
06-20-2007 · EurekAlert!Pancreatic cancer (PC), the subject of this thesis, has the poorest prognosis of all cancers: the survival rate after five years with the disease is less than five percent and on average, patients who have been diagnosed with it do not live longer than six months.

- Molecular differences between early and advanced melanomas could provide new drug targets
03-12-2007 · EurekAlert!
The cell-signaling molecule Akt is a primary trigger that leads malignant melanomas on the skin's surface to begin growing vertically beneath the skin and turn into deadly invasive cancers, scientists have found. Understanding this key molecular difference between radial melanomas that spread on the surface of the skin and melanomas that grow vertically and invasively could provide new targets for the development of drugs to treat individuals with advanced stage melanomas.

- Measuring brain activity for emotional markers that may indicate risk for developing alcoholism
11-26-2006 · EurekAlert!
New research uses an electroencephalogram to look for a connection between brain activity thought to reflect trait-like differences in emotionality and alcoholism. Findings show an asymmetry of activity in the left and right frontal areas of the brain. The pattern of asymmetry found is similar to that found in individuals with depression.

- Species detectives track unseen evolution
07-18-2007 · EurekAlert!
New species are evading detection using a foolproof disguise -- their own unchanged appearance. Research published in the online open access journal, BMC Evolutionary Biology, suggests that the phenomenon of different animal species not being visually distinct despite other significant genetic differences is widespread in the animal kingdom. DNA profiles and distinct mating groups are the only way to spot an evolutionary splinter group from their look-alike cousins, introducing uncertainty to biodiversity estimates globally.

- How are phenotypic differences between sexes related to phenotypic variation within sexes?
01-10-2007 · EurekAlert!
It has long been recognized that sexually dimorphic traits -- traits that are systematically different between members of different sex in the same species, such as peacocks' tail feathers -- tend to vary a great deal among individual males, and that much of this within-sex variation depends on individual condition. Indeed, theory predicts that sexual dimorphism will evolve based on condition dependence so that, among traits, a more pronounced difference between male and female should be associated with a stronger response to variation in condition.

- Survey shows gender differences are factor when surgeons in training choose a subspecialty
11-09-2007 · EurekAlert!
A gender difference exists among surgeons who choose a surgical subspecialty, particularly when they evaluate the factors that may influence their career choice, according to results of a new survey published in the November issue of the Journal of the American College of Surgeons.

- Rebel with a cause: Why certain products are used as markers of difference
07-12-2007 · EurekAlert!
Teens want to distinguish themselves from their parents. Rich Brits stopped buying Burberry once it became the brand of choice for soccer hooligans and Shanghai urbanites avoid the Volkswagen model that is preferred by the suburban nouveau riche. Yet, the same teens who wouldn’t be caught dead wearing the same jeans as their parents have no problem using the same brand of detergent. A new study by Stanford researchers explores why some products are used by people to differentiate themselves from certain social groups.

- Researchers discover possible markers for mental illness
12-03-2007 · EurekAlert!
Researchers have discovered natural genetic differences that might help predict the most effective antipsychotic drugs for particular patients with mental disorders such as schizophrenia, Parkinson's and drug addiction. They found the differences in the gene for a molecule called the dopamine D2 receptor, a protein present on brain cells that are sensitive to the neurotransmitter dopamine.

- Global ocean sampling expedition
03-13-2007 · EurekAlert!
The Sorcerer II GOS expedition, data sampling and analysis is described. The immense diversity in the sequence data required novel comparative genomic assembly methods, which uncovered genomic differences that marker-based methods could not. The GOS data identified 6.12 million predicted proteins covering nearly all known prokaryotic protein families, and several new families. This almost doubles the number of known proteins and shows that we are far from identifying all the proteins in nature.
