Researchers discover oldest evidence of 'farming' -- by insects
June 23, 2016 04:56 PM - National Science Foundation via EurekAlert!

Scientists have discovered the oldest fossil evidence of agriculture -- not by humans, but by insects.

The team, led by Eric Roberts of James Cook University along with researchers from Ohio University, discovered the oldest known examples of "fungus gardens" in 25 million-year-old fossil termite nests in East Africa.

The results are published today in the journal PLOS ONE.

Some termite species cultivate fungi in "gardens" in subterranean nests or chambers, helping to convert plant material into a more easily digestible termite food source.

National Academy of Sciences Weighs In On Genetically-Engineered Foods
June 1, 2016 01:58 PM - Jan Lee, Triple Pundit

The National Academy of Sciences has some conclusions to share about genetically-engineered foods — 420 pages worth. And no matter which side of the fence you stand on when it comes to this divisive topic, you probably aren’t going to like what the nonprofit has to say.

The report, Genetically Engineered Organisms: Experiences and Prospects, was released last week online amid a flurry of news articles that attempted to breathlessly summarize the findings in a few short sentences. Some expressed disappointment in the authors’ inconclusive findings; many others attempted to pin a final yea-or-nay viewpoint on the Academy’s nine-chapter investigation.

The Great Green Wall of Africa

Llowell Williams, Care2

Though a border wall with Mexico is currently a matter of serious discussion in the United States, the aim of which is to prevent the physical movement of people (with few other apparent “benefits”), some walls can actually bring together and preserve communities, rather than divide them.

In only five years, the UN says, around 60 million Africans may be displaced as their land ceases to be arable, a potential humanitarian disaster the scale of which would be unprecedented. This would be devastating to a huge portion of the African continent not only ecologically and economically but socially as well.

That’s where Africa’s ingenious Great Green Wall comes in.

Experts at the United Nations say without action, desertification may claim two-thirds of Africa’s farmlands in under a decade. The Great Green Wall, however, was conceived as a wide-reaching strategy to halt Northern Africa’s rapidly advancing Sahara Desert.

The Great Green Wall, once complete, will stretch an incredible 4,400 miles from Senegal in West Africa to the East African nation of Djibouti. Instead of bricks and mortar, the wall will be made of trees and other vegetation, including plants that can be eaten or used to create medicine.
