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.

Exploring the protective systems that keep the power grid from self destructing.

We usually think of the power grid in terms of its visible parts: power plants, high-voltage lines, and substations. But, much of the complexity of power grid comes in how we protect it when things go wrong. When your power goes out, it’s easy to be frustrated at the inconvenience, but consider also being thankful that it probably means things are working as designed to protect the grid as a whole and ensure a speedy and cost-effective repair to the fault.

Into the Fray: How NBC's Washington Documentary Unit Reinvented the News By Tom Mascaro

https://www.amazon.com/Into-Fr....ay-Washington-Docume

The Science of Spying, marked the arrival of Bob Rogers as a field reporter-producer. The program aired May 4, 1965, and tracked the roots of U.S. covert operations back to the 1950s, providing a stark account of clandestine initiatives in a time before public disclosures, congressional investigations, and Hollywood movies made the 1970s a difficult time to be an American spy. The "Pentagon Papers," the Pike and Church Committees, and thrillers such as Three Days of the Condor eventually revealed the CIA's complicity in assassination plots and interna-tional meddling, which Yates and Rogers had already seen up close. NBC management stood firm when The Science of Spying attracted criti-cism. Ad reps from Batten, Barton, Durstine & Osborn (BBD&O) screened it and advised their client B. F. Goodrich Company to withdraw.31 BBD&O issued a statement saying the program violated the Goodrich advertising policy "in that it treats a controversial public issue in a way which may do harm to the government of the United States?" NBC countered that the documentary "fell within the broad outlines of the program policy origi-nally submitted to and accepted by the B. F. Goodrich agency, BBD&O."33 The CIA watched the program and tracked subsequent reactions in the national press. Viewers wrote to President Johnson complaining NBC News had given America's enemies negative propaganda.34 Yates may have antici-pated some adverse reactions to the program, but he never expected to be frightened by what he discovered.

Considered to be the King of Ragtime, Scott Joplin spent most of his life in the American south, between Missouri and New Orleans. Joplin’s natural skills and a combination of gospel hymns, spirituals, dance music, classical music and work songs contributed significantly to the invention of a new style called “Ragtime”, giving America a genuine native music. Here are 27 marvellous rags from his songbook, played by Ania Safa, all dating back to the early 1900s. More than a century later, Scott Joplin’s music is still just as modern, dazzling and fresh.

Bayyinah Bello Profile:
Bello is the mother of four, grandmother of 10 and great grandmother of 4. She first earned an Administrative degree at New York State University. Then went on to gain a B.S. in Education and an M.S. in Linguistics. Bello taught Arabic at Muhammad University of Islam. She discovered the joy of writing and published several language manuals and children storybooks.

Bello has lived in Liberia, Nigeria and Togo. She’s visited all the West African countries and several others on the continent. Back in the United States Bello worked as a publicist for the Museum of Natural History.

After gaining a Masters Degree in Primary Education and more teaching experience, Bello returned to Haiti. There, she taught the Hausa language and culture at the State University of Haiti. She also founded the ‘Citadelle International School,’ a bilingual school for Primary & Secondary aged children, aiming to aid young Haitians returning home to adapt.

Professor Bello teaches anthropology at the State University of Haiti. She is among the few professional educators to have dedicated her life’s work to the struggle for human rights and dignity for our peoples across the planet. A humanitarian and advocate, Professor Bello continues to contribute time and resources to assist in the development of programs based on a procedure she conceived. It states that the greatest knowledge is the knowledge of Self. Once one has developed the knowledge of Self one has no basis to envy another, to desire that which is not naturally yours, to promote or practice corruption; …one is empowered to generate reciprocity which is the foundation from which springs abundance and prosperity. Professor Bello is fluent in Haitian Kreyòl, French, English, Arabic and Hausa. She is currently working as Professor at the State University of Haiti.

Professor Bello was featured as a leading Haiti scholar and historian in the documentary 1804: The Hidden History of Haiti.
