This is an Afrometrics News, A Research-Based News Podcast, upload covering emerging research from the previous week. You may visit Afrometrics at Afrometrics.org for more.

This episode is another special one, we have a special guest, Dr. Kendall Ware who is a Professor of Mathematics. He joined me for a discussion of his very interesting study titled "The Effect of Black Educators on Black Students' Beliefs Towards Mathematics."

How can we feed the world—today and tomorrow?

The biggest players in the food industry—from pesticide pushers to fertilizer makers to food processors and manufacturers—spend billions of dollars every year not selling food, but selling the idea that we need their products to feed the world. But, do we really need industrial agriculture to feed the world? Can sustainably grown food deliver the quantity and quality we need—today and in the future? Our first Food MythBusters film takes on these questions in under seven minutes. So next time you hear them, you can too.

As part of the 2030 Agenda for Sustainable Development, achieving a world without hunger and malnutrition calls for urgent action to make agriculture more sustainable, productive and resilient.

The impacts of climate change are further increasing uncertainties and vulnerabilities facing farmers and communities.

Integrated, cross sectoral approaches like agroecology are an important element in the transition process, reducing the environmental footprint of agriculture to guarantee healthy ecosystems that can ensure food and nutrition security for all.

On the base of case studies and interviews from farmers, researchers and decisions makers from France, Mali, Hungary , Argentina this video show how agroecology and political will can help build more resilient farming systems and question the future requirements to up-scale these solutions.

JAYAPURA (Café Pacific): The current armed conflict between West Papuan National Liberation Army (TPNPB) and Indonesian Military Forces in Nduga, West Papua, are demonstrated in this video released by TPNPB News.

This video was taken a few months ago in Nduga when Indonesia dropped military personnel in an airborne operation.

On a different occasion, the same helicopter dropped an internationally banned weapon, white phosphorous, in December 2018, and in some different places dropped live bombs, according to TPNPB News.

On 27 January 2018, a war ultimatum was announced by the National Operation Comander of TPNPB, the military wing of OPM armed resistance, Legakek Tellengen in Puncak Jaya.

Researchers have offered a chemical explanation for sex change in a tropical fish. ↓↓More info and references below↓↓

For a tropical fish called the bluehead wrasse, sex isn’t always permanent. When a group of the fish loses its dominant male, the biggest female rapidly changes sex, taking on distinctive male coloring and producing mature sperm in as little as 8 days. Although this change is well documented, the molecular mechanisms that drive it have remained unclear. Now, an international group of researchers has offered a chemical explanation for the transformation after analyzing tissue samples from transitioning fish.
