Mineral studies advance antibacterial alternatives
03/19/2010 - 13:00
Alternative approaches to medicine are stock-in-trade in the Arizona State University laboratory of microbiologist Shelley Haydel. So when ASU senior Jenny Koehl joined Haydel's investigative team seeking firsthand knowledge of how basic research is done, how drugs are tested and potential cures produced, she found it and much more.

Earlier butterfly emergence linked to climate change
03/19/2010 - 07:00
Butterflies are emerging in spring over 10 days earlier than they did 65 years ago, a shift that has been linked to regional human-induced climate change in an Australian-led study. The work reveals a causal link between increasing greenhouse gases, regional warming and the change in timing of a natural event.

Estimating ethanol yields from Conservation Reserve Program croplands
03/18/2010 - 23:00
The scramble to find sufficient land for biofuel production has experts eyeing marginal croplands that have been placed in the Conservation Reserve Program (CRP). Now a new study indicates that plant species diversity and composition are key factors in potential energy yield per acre from biomass harvested from CRP land.

Prescribed burns may help reduce US carbon footprint
03/18/2010 - 13:00
The use of prescribed burns to manage Western forests may help the United States reduce its carbon footprint. A new study finds that such burns, often used by forest managers to reduce underbrush and protect bigger trees, release substantially less carbon dioxide emissions than wildfires of the same size.

How can accidental captures of loggerhead turtles be reduced?
03/18/2010 - 04:00
Scientists have studied interactions between the loggerhead turtle (Caretta caretta) and fishing gear such as longline hooks used at the water surface, mass beachings, and the effects of climate change on these animals. In order to reduce captures of this marine species without causing economic losses for fishermen, the scientists are proposing that fishing in the summer should only be carried out by night and in areas more than 35 nautical miles from land.

Multifunctional polymer neutralizes both biological and chemical weapons
03/17/2010 - 23:00
In an effort to mirror the ability of biological tissues to respond rapidly and appropriately to changing environments, scientists have synthesized a single, multifunctional polymer material that can decontaminate both biological and chemical toxins.
