Researchers call for more research but comprehensive 12-country analysis suggests hungry region produces only 10% of possible wheat yield; could become more self-sufficient in wheat production as hedge against rising expensive imports In releasing the first ever comprehensive report on sub-Saharan Africa's economic and biological potential for producing wheat, scientists said today that the region's farmers may be growing only 10 to 25 percent of the production the research suggests is...

Genes Associated With Genomic Expansions That Cause Disease Identified
2012-09-10 11:49:17

Examining trinucleotide repeats A study of more than 6,000 genes in a common species of yeast has identified the pathways that govern the instability of GAA/TTC repeats. In humans, the expansions of these repeats is known to inactivate a gene — FXN — which leads to Friedreich's ataxia, a neurodegenerative disease that is currently incurable. In yeast, long repeats also destabilize the genome, manifested by the breakage of chromosomes. Working with collaborators at Tufts...

Planarian flatworms have come under intense study for their renowned ability to regenerate any missing body part, even as adults. But now they may take on a starring role as a model system for studying eye development and eye diseases in vertebrates, including humans. This expansion of the planarian job description comes courtesy of Whitehead Institute researchers, who this week are publishing in Cell Reports an exhaustive catalog of genes active in the planarian eye. "It's exciting to...

Candidate gene controls IGF1 levels, affecting both onset of reproductive maturity and longevity An intriguing clue to longevity lurks in the sexual maturation timetable of female mammals, Jackson Laboratory researchers and their collaborators report. Jackson researchers including Research Scientist Rong Yuan, Ph.D., had previously established that mouse strains with lower circulating levels of the hormone IGF1 at age six months live longer than other strains. In research published May...

Ossabaw Island Hog
2014-09-02 09:37:37

The Ossabaw Island hog, also known as the Ossabaw Island, is a breed of pig that developed from a herd of feral pigs on Ossabaw Island, Georgia in the United States. The original population of hogs was brought to the island by the Spaniards during the sixteenth century for the purpose of later consumption, which was a typical practice during Spanish exploration at that time. The pigs became isolated on the island for hundreds of years and had little interaction with domestic pig breeds or...

2014-08-21 10:26:56

The western clawed frog is also known as the tropical clawed frog and is found widespread in the regions of Nigeria, Liberia, Gambia, Guinea, Cameroon, the Ivory coast, and surrounding areas. The habitat for the western clawed frog is moist areas in tropical and subtropical rivers, lakes, marshes, swamps, agricultural ponds, and canals. The body color of the western clawed frog is light to dark brown and covered with grey and black spots. The eyes protrude up from the head. Tubercles...

Fraser’s Clawed Frog, Xenopus fraseri
2014-08-21 10:15:53

The Fraser’s clawed frog also known as Fraser’s platanna is wide spread with an abundant population throughout Angola, Cameroon, Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Gabon and Rwanda. The habitat of this species of frog is tropical and subtropical lowlands where there are forests, rivers, freshwater lakes, marshes, ponds and streams. The Fraser’s clawed frog is a water dependent species using it for living and...

African Clawed Frog, Xenopus laevis
2014-08-18 16:16:15

The African clawed frog is found in its natural habitat throughout Africa. However, it has been introduced in North America, South America and Europe. This species is fully aquatic and is found abundantly in ponds, lakes, and rivers. The body color of the African clawed frog is a greenish grey and the skin is smooth and slippery with blotches of grey or brown on the back. The belly is a cream colored with a yellow tint. The average length of this species is five inches. The body and head...

Auckland Island Pig
2014-08-07 11:44:58

The Auckland Island pig is a breed of feral pig that resides on Auckland Island in New Zealand. During the eighteenth and nineteenth centuries, domestic pigs were released onto many sub-Antarctic islands, including Auckland Island, by Europeans who wanted stranded sailors or whalers to have a steady supply of food when visiting these uninhabited islands. This process began in 1807 and after several other releases occurring between 1840 and the 1890’s, the pigs began to establish a healthy...
