It's electric: Cows show promise as powerplants

... usually leaves behind plenty of it in the form of crop residue in the fields. The other chamber, the cathode, was filled with potassium ferricyanide, a chemical that acts as an oxidizing agent to round out the electrical circuit. Two small pieces of plain graphite served as the fuel cell's electrodes (...

FDA approves more generic AIDS drugs

...tions a year rather than just one or two like most crop plants. That rapid reproduction allows them to study the plant's genetics faster than they could with other species. Understanding Arabidopsis completely will teach scientists an enormous amount about all other flowering plants, which are closely re...

UNC plant researchers discover proteins interact to form hair-trigger protection against invaders

Understanding Arabidopsis completely will teach scientists an enormous amount about all other flowering plants, which are closely re...

Genome study of beneficial microbe may help boost plant health

In a study expected to greatly benefit crop plants, scientists have deciphered the genome of a root- and seed-dwelling bacterium that protects plants from diseases. The research provides clues to better explain how the helpful microbe, Pseudomonas fluorescens Pf-5, naturally safeguards roots ...

Key to elephant conservation is 'in the sauce'

... human food, but has also introduced a viable cash crop to the economy of African nations. "Chilli pepper...lly, farmers use chilli peppers to deter potential crop raiders in two ways: as a protective buffer crop to surround core crops of maize, sorghum and millet...

Grass makes environmentally friendly biofuel

NHGRI targets 12 more organisms for genome sequencing

...ct which causes hundreds of millions of dollars of crop damage each year. The pea aphid is a model for stu...id wasps in agriculture as a biological control of crop damaging insects saves approximately $20 billion annually. The wasp will serve as a good comparison ...

Butterfly migration could be largest known

...infall in southern California has created a bumper crop of plants for the caterpillars to eat, fuelling a population boom, Shapiro said. The butterflies take about three days to reach the Central Valley, and the current generation will fly as far as southern Oregon. Their offspring will fly on to reach B...

Researchers find gene that may be at root of potato blight

...ations particularly hard, as potatoes are a staple crop in many of these countries. P. infestans belongs to a group of destructive pathogens called oomycetes. Oomycetes aren't easy to categorize ?although they physically look like fungi, on a molecular level they more closely resemble algae. Over the la...

Sugar beet virus mutation requires Texas touch

...e to have an understanding of everything, from the crop growing in the field to the molecular aspects of the pathogen. That makes our program totally unique." Outside research dollars began pouring in and Rush's program was reinvigorated in 2002 when a new strain of beet necrotic yellow vein virus emerge...

Nature provides inspiration for important new adhesive

...tofu. "Soy beans, from which tofu are made, are a crop that's abundantly produced in the U.S. and has a very high content of protein," Li said. Soy protein is inexpensive and renewable, but it lacks the unique amino acid with phenolic hydroxyl groups that provide adhesive properties. Li's research group ...

Roots Engage in Underground Chemical Warfare

...t. The work paves the way to understand and combat crop diseases." The program manager for Ausubel's award, Michael Mishkind said, "The puzzle of why so few bacterial species are pathogens remains a fascinating problem. The simple, yet elegant experimental approaches used by this team uncovered a critica...

Scientists discover how plants disarm the toxic effects of excessive sunlight

...rotective pathway, "we could be able to get larger crop yield per photon of light," he says. And by making cells more resistant to singlet oxygen, scientists may be better able to design bioenergy systems that use sunlight as an alternative to traditional fossil fuels. "By understanding how biology solve...

Researchers discover chemical compounds that affect plant growth

...l species to improve agronomic traits and increase crop value," said research team leader, Distinguished Professor of Plant Cell Biology Natasha Raikhel. The team published its findings in this week's issue of the Proceedings of the National Academy of Sciences in a paper titled, The Power of Chemical Ge...

Genetically modified rice in China benefits farmers' health, study finds
