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.

New decontamination system kills anthrax rapidly without lingering effects
01-29-2008 · EurekAlert!
Researchers have developed prototypes of a rapid, non-disruptive and less expensive method to decontaminate bioterrorism hazards. Using flat panels that produce X-rays and ultraviolet-C light, the researchers can kill anthrax spores, even hidden ones, in two to three hours without any lingering effects.

How fish species suffer as a result of warmer waters
01-04-2007 · EurekAlert!
In order to estimate future changes, it is essential to develop a deeper understanding of the effect of water temperature on the biology of organisms under question. A new investigation, just published in the scientific journal Science, reveals that a warming induced deficiency in oxygen uptake and supply to tissues is the key factor limiting the stock size of a fish species under heat stress.

Increase in ethanol production from corn could significantly impact
10-10-2007 · EurekAlert!
If projected increases in the use of corn for ethanol production occur, the harm to water quality could be considerable, and water supply problems at the regional and local levels could also arise, says a new report from the National Research Council.

Soil nutrients shape tropical forests, large-scale study indicates
01-11-2007 · EurekAlert!
Tropical forests are among the most diverse plant communities on earth, and scientists have labored for decades to identify the ecological and evolutionary processes that created and maintain them. A key question is whether all tree species are equivalent in their use of resources -- water, light and nutrients -- or whether each species has its own niche.A large-scale study by researchers at the University of Illinois at Urbana-Champaign and eight other institutions sheds some light on the issue.

Circadian clock controls plant growth hormone
08-10-2007 · EurekAlert!
The plant growth hormone auxin is controlled by circadian rhythms within the plant, UC-Davis researchers have found. The discovery explains how plants can time their growth to take advantage of resources such as light and water, and suggests that many other processes may be influenced by circadian rhythms.
