A new survey shows we have barely tapped the surface of potential medicines beneath our feet.Science Daily reported on a study of three desert soils from California, Arizona and Utah published in the May issue of Applied and Environmental Microbiology. A team from Howard Hughes Medical Institute found “greater diversity of potentially useful products than was previously supposed” in the biosynthetic genes of soil bacteria, implying that “environmental bacteria have the potential to encode a large additional treasure trove of new medicines.” The article explained where most of our medicines come from:Natural compounds have been the sources of the majority of new drugs approved by the US Food and Drug Administration, and bacteria have been the biggest single source of these therapeutically relevant compounds. Most bacterially-derived antibiotic and anticancer agents were discovered by culturing bacteria from environmental samples, and then examining the metabolites they produce in laboratory fermentation studies. But the vast majority of bacterial species cannot be cultured, which suggested that the world might be awash in potentially useful, but unknown bacterial metabolites.It seems that researchers will not soon run out of material to investigate: “the genomes of environmental bacteria could encode many additional drug-like molecules, including compounds that might serve, among other things, as new antibiotics and anticancer agents.”When you think of bacteria, do you think of health? Maybe findings like this will help end a kind of microbial racism. A few bad ones should not create bias against the majority that work hard to create a better world.This survey also suggests that bacteria originally had a useful function in the Creation paradigm.
6 May 2016Brand South Africa presented an overview of the organisation and its efforts to encourage competitiveness in Africa at the 2016 Junior Chamber International (JCI) Africa and Middle East Conference, held in Johannesburg from 4 to 7 May 2016.

The aim of the workshop, and the conference itself, was to harness effective youth development practices to engage young people in the active roles they can take to build social cohesion.Delegates included JCI president Paschal Dike of Nigeria, and Tshepo Thlaku, chairman of the 2016 JIC event and president of JCI South Africa.The BSA presentation highlighted the many strides the country has made in building its reputation in Africa and the world. It also looked at the social and economic advancement of the country through active citizenship and a strong focus on trade and industrial competitiveness.The presentation aimed, in the words of the Brand South Africa slogan, to inspire new ways to motivate other African countries to become storytellers for the continent.#LatestIssue: @Brand_SA CEO Kingsley Makhubela on branding SA positively despite issues: https://t.co/ftCdU7EL4D pic.twitter.com/7L9WUSlGq9— Destiny Man (@Destiny_Man) March 31, 2016In his keynote address, Makhubela spoke about how young people have the ability and passion to continuously change the world. He used the examples of both the 40th anniversary of the 1976 Soweto student uprisings and last year’s #FeesMustFall demonstrations.“South African youth demonstrated how they could come together and collectively fight for a cause that would change the conditions for millions of young people in our country,” Makhubela said. “Education is a critical enabler for development and equally for national competitiveness. The youth of South Africa did more than just fight for no increases and additional funds, they are fighting for the country’s very development.”Turning to global issues, particularly those affecting Africa and the Middle East, Makhubela said youth power was key to spreading democracy and reducing inequality. “Young people are playing a critical role in raising levels of awareness about the unsustainability of current frameworks and paradigms,” he said.Concluding, Makhubela emphasised that young people must understand that with every right comes a responsibility to change the world without destroying it. He quoted the African Union’s Agenda 2063 for long term growth and development on the continent, which states: “Present generations are confident that the destiny of Africa is in their hands, and that we must act now to shape the future we want.”Annually, the JCI conference brings together over 1 000 young active citizens, representing more than 50 partner countries from Africa, the Middle East and Europe. The attendees participate in a host of inspirational sessions, practical workshops, meetings with important political and economic players, as well as fun social events. These all encourage emerging young talent to share best practices, exchange ideas and determine the future of the organisation and the young people in the regions it represents.SouthAfrica.info reporter
Share Facebook Twitter Google + LinkedIn Pinterest High temperatures at the beginning of the week helped dry out fields for some planting but spotty rains toward the end of the week delayed further planting. There were 4.4 days suitable for fieldwork in Ohio during the week ending May 21, according to Cheryl Turner, Ohio State Statistician with the USDA ’ s National Agricultural Statistics Service. Producers were able to plant corn and soybeans before the rain set in but now are experiencing problems with excess moisture. A significant amount of fields had to be replanted, and many farmers had to return to fields to handle soil crusting. Many growers took advantage of a window of opportunity to put up their first cutting of hay.73% of corn was planted, up from 49% the week before. Corn emerged increased 17% from the week before to 41%.Soybeans made a big jump at 43% planted, a rise from the 19% of the week before.Read the full report here.
