X-rays reveal patterns in the plumage of the first birds

1000pa (June 30, 2011) — Scientists report that they have taken a big step in determining what the first birds looked like more than 100 million years ago, when their relatives, the dinosaurs, still ruled Earth. At the Department of Energy's SLAC National Accelerator Laboratory, they discovered chemical traces of a pigment, an important component of color, that once formed patterns in the feathers of the fossilized birds.

The pigment,...

Pigment patterns from the prehistoric past

1000pa (June 30, 2011) — An international collaboration led by researchers at the University of Manchester has for the first time revealed chemical traces of pigments in bird, fish and squid fossils, some over 100 million years old.

Publishing their findings in Science, the researchers have been able to show a remarkable relationship between copper and pigment within exceptionally preserved feathers and other soft tissues.

Results include...

New fossils demonstrate that powerful eyes evolved in a twinkling

1000pa (June 30, 2011) — Palaeontologists have uncovered half-a-billion-year-old fossils demonstrating that primitive animals had excellent vision. An international team led by scientists from the South Australian Museum and the University of Adelaide found the exquisite fossils, which look like squashed eyes from a recently swatted fly.

This discovery will be published on June 30, 2011) in the journal Nature. The lead author is Associate...

Student publishes case for faster, less expensive DNA analysis

1000pa (June 28, 2011) — A Washington State University student's undergraduate research is challenging a widely held assumption on the best way to analyze old DNA in anthropological and forensic investigations.

Sarah "Misa" Runnells' claim is weighty enough to be published this week in the peer-reviewed, online journal PLoS ONE.

At issue is the best way to sequence "ancient" DNA, bits of genetic code pulled from remains up to 800,000 years...

Patterns of ancient croplands give insight into early Hawaiian society, research shows

1000pa (May 16, 2011) — A pattern of earthen berms, spread across a northern peninsula of the big island of Hawaii, is providing archeologists with clues to exactly how residents farmed in paradise long before Europeans arrived at the islands.

The findings suggest that simple, practical decisions made by individual households were eventually adopted by the ruling class as a means to improve agricultural productivity.

The research was...

Wine yeasts reveal prehistoric microbial world

1000pa (May 11, 2011) — When having a glass of wine or beer, have you ever wondered why and how yeast "learned" to produce these superb food products? Yeasts are unicellular fungi and so far over 1,500 different species have been described. Among them are important industrial organisms, pathogens and model organisms which help us to understand how eukaryotic cells work.

However, one of the most well-known characteristics of yeast is the...
