Molecular detectors may refine cancer treatment

... technique could be useful to detect the molecular fingerprints of cancer in people. The next step toward developing a clinical diagnostic tool involves matching patient data with these molecular profiles. The research team working with W.

Modern brains have an ancient core

...give it its identity. The similarities between the fingerprints of vasotocin and RF-amide-secreting cells in zebrafish and Platynereis are so big that they are difficult to explain by coincidence. Instead they indicate a common evolutionary origin of the cells. It is likely that they existed already in Urbilateri...

Volcanic eruptions, ancient global warming linked

...the peak of the volcanic eruptions. Using chemical fingerprints and identical ages, they were able to positively match ash layers in east Greenland with those in marine sediments in the Atlantic Ocean. "We think the first volcanic eruptions began about 61 million years ago and then it took another 5 million yea...

"Such a complex arrangement caould not have been invented twice throughout evolution, it must be the same system," adds Gspr Jkely, a researcher from Ar...

'Ancestral eve' was mother of all tooth decay

...n his analysis of the bacterium, Caufield used DNA fingerprints and other biomarkers that scientists have also employed to trace human evolution back to a single common African ancestor, known as "ancestral Eve." "As humans migrated around the world and evolved into the different races and ethnicities we know...

They likened metabolomics to analyzing the contents of a trash can in or...

Learning to live with oxygen on early Earth

... how they metabolize it. Changes in these chemical fingerprints tell us about changes in how organisms got their energy and food." In the Archean, microbes that could not live with oxygen--anaerobic organisms--ended up with relatively small amounts of 13C. As oxygen became available in shallow water due to oxyg...

Researchers quantify more noise in gene expression

Human identical twins have different fingerprints and march to the beat of subtly different phenotypes, an indication of heterogeneity which led bioengineering researchers at the University of California, San Diego (UCSD) to devised computer algorithms that identify the underlying sources of variati...
