The research by the University of Southampton’s Coral Reef Laboratory shows that some corals exhibit a dazzling colourful display when they suffer bleaching due to warmer temperatures—to protect themselves.
The university’s scientists found that glowing colours in bleached corals act like a protective layer (similar to sunscreen) when symbiotic micro-algae are lost. The vivid colours are also a blinking neon sign that encourages the algae to return. The study suggests that corals develop extreme colouration within 2 to 3 weeks after exposure to mild or temporary heat stress.

NEW YORK, Jul 20 2020 (IPS)* – “We may all come on different ships, but we are in the same boat now,” Martin Luther King Jr once said. His timeless wisdom rings truer than ever today for the many challenges the world is facing. COVID-19, continued armed conflicts and forced displacement, climate-change induced disasters, deep divides and widespread discrimination mark the human family in the 21st century.

One that is holistic and empowers the young generation, especially girls, to realize their potential, be productive and bring lasting peace to their communities and the world.

20 July 2020 (UN Environment)* — There was a time when industrial agriculture seemed to be a panacea for a fast-growing world. Synthetic fertilizers, chemical pesticides and high-yield cereal hybrids promised to reduce hunger, accommodate growing populations and stimulate economic prosperity. Between 1960 and 2015, agricultural production more than tripled, resulting in an abundance of low-cost fareand averting global food shortages.
