- In matters of sex and death, men are an essential part of the equation
08-28-2007 · EurekAlert!
In a paper, to appear in the August 29 issue of the online, open-access journal PLoS ONE, Stanford scientists show that the standard practice of tracking only female life histories leads to mistaken conclusions about the forces that shape human evolution. The reason is that men's and women's age patterns of fertility differ in important ways.

- Dung happens and helps scientists
02-15-2008 · EurekAlert!
A scientist at Northern Arizona University is in charge of the largest animal dung collection in the world, used for clues about animal evolution and extinction, Ice Age existence and climate change. Researcher Jim Mead admits it is a bizarre resource, but he is one of many around the globe who access dung for DNA information. Mead, a dung authority, continues to grow the collection with specimens from as far away as Siberia.

- With computers, astronomers show predicted present day distribution of elusive first stars
12-11-2006 · EurekAlert!
With the help of enormous computer simulations, astronomers have now shown that the first generation of stars -- which have never been observed by scientists -- should be distributed evenly throughout our galaxy, deepening the long-standing mystery about these missing stellar ancestors. The results are published in this week's issue of the Astrophysical Journal.

- Scientists crack rhino horn riddle
11-06-2006 · EurekAlert!
Rhinoceros horns have long been objects of mythological beliefs. Some cultures prize them for their supposed magical or medicinal qualities. Others have used them as dagger handles or good luck charms. But new research at Ohio University removes some of the mystique by explaining how the horn gets its distinctive curve and sharply pointed tip.

- Genetic background to severe urinary tract infections
09-04-2007 · EurekAlert!
If you sit on cold boulders or forget to wear your woollen pants, you can develop a urinary tract infection. However, these diseases are more complicated than this, and in some cases they have a genetic background. Scientists at Lund University in Sweden have found a gene that appears to lie behind many of the most severe urinary tract infections. The study is published September 5 in the online, open-access journal PLoS ONE.

- How one pest adapted to life in the dark
12-20-2007 · EurekAlert!
A type of beetle that lives its entire life burrowing through stored grain has been found to lack full-color vision, and what's more the vision it does have breaks the rules. Most other insects have trichromatic vision -- they are sensitive to ultraviolet, blue and long wavelength light. In a report published in the online open access journal Frontiers in Zoology, scientists reveal that this beetle has lost photoreceptors that are sensitive to blue wavelengths.

- Arizona State University scientist finds Martian ice is patchy and variable
05-02-2007 · EurekAlert!
For the first time, scientists have found that water ice lies at variable depths over small-scale patches on the Red Planet. The discovery draws a much more detailed picture of underground ice on Mars than was previously available. The new results, by a researcher in Arizona State University's School of Earth and Space Exploration, will appear in Nature. The findings come from data sent back to Earth by THEMIS on NASA's Mars Odyssey orbiter.
