Did you know there are large, unexplained swarms of jellyfish along South Africa’s
coastlines? Most beachgoers know little about these sea creatures other than their
ability to sting. Their misunderstood nature makes it difficult to appreciate and protect
them. The rich diversity of jellies swimming around remain largely unacknowledged
and unstudied. Krish Lewis, known as the “jelly guy”, is on a mission to discover more.
The marine biologist works at the Two Oceans Aquarium, where the jellyfish exhibit is
his focus. Lewis cares for a range of species, including the rare pink meanie jellyfish,
named for its colouring and love for eating other jellyfish. But his favourite is the
Benguela compass jelly, which is endemic to South Africa. Since 1997, scientists have
been trying to grow the species through all life stages in labs. Lewis became the first to
close the life cycle – a huge feat in cnidology.
Since 2012, he has been growing jellyfish from polyps – a stalk that develops from
fertilised eggs, then attaches to coastal reefs and pops off baby jellies. Lewis notes that
the most rewarding part of his job is watching them change physically. South Africa is
home to 20 species of ‘true’ jellyfish, which make up 10% of the global total. Many of
these remain misclassified. “In order to conserve and understand them, we need to find
out what we have,” Lewis says.
By studying these life forms, we can ensure a balanced ecosystem. The bubble-like
organisms support a large diversity of underwater fauna and flora, which we’re
extremely lucky to have. Dedicated aquarists such as Lewis are revealing their value
and uncovering the mysteries of jellyfish.

Artscape has partnered with community, regional and national radio stations across the country to bring the 2020 New Voices Programme to individual South African households as radio dramas over a two-month period from June to August.
The project seeks to give an opportunity to young writers as well as restoring dignity and confidence to those who have been disregarded and under-represented in the past.

Food Flow is a new initiative pioneered during this crisis in Cape Town – with donations they buy produce from small-scale farmers who would usually supply the restaurant business – to make up essential vegetable boxes to distribute to communities facing food insecurity.
Thus, protecting the supply chain for the future, keeping small farmers afloat – Food Flow shifts the flow of produce coming from farms to those most vulnerable.
FoodFlow then matches the farmer with a community organization in their vicinity who distributes harvest bags or cooks a meal for their beneficiaries. FoodFlow works to sustain food livelihoods, enabling farmers to continue sustaining their business despite the loss of restaurant, hotel and market clients and ensures fresh nutritious food keeps flowing to those who are most impacted by food insecurity

The last few months have been tough on the education sector.
Schools were one of the first institutions to shut down even before the nationwide lockdown was announced and soon all classes turned digital.
As the economic repercussions of lockdown led to job losses and pay cuts, many parents found themselves battling to pay school fees.
The effects have been dire. But one school refuses to go down without a fight.

The launch of NASA’s next Mars rover mission has been delayed to no earlier than July 30 because of a launch vehicle processing issue, the latest in a series of slips that have now used up nearly half of the available launch opportunities for the mission.
NASA announced June 30 that the mission, previously scheduled to launch July 22, would be delayed to investigate “off-nominal” data from a liquid oxygen sensor line during a wet dress rehearsal of the mission’s Atlas 5 launch vehicle June 22 at Cape Canaveral, Florida - according to SpaceNews.com.
The mission was originally scheduled to launch July 17, the beginning of its launch period, but has slipped three times. None of the slips have had to do with issues with the Mars 2020 spacecraft itself - NASA announced.
The Mars 2020 project (carrying a rover named Perseverance) will land on Mars on Feb. 18, 2021, regardless of what day it launches during the current launch period. The rover will land in Jezero Crater on Mars for mission designed to last at least one Martian year, or 687 Earth days. Perseverance’s instruments will reportedly look for signs of past life on Mars, but the mission’s biggest purpose is to cache samples of Martian rock for later return to Earth.
