https://earthwiseradio.org/wp-content/uploads/2018/08/EW-09-10-18-Hippo-Pools.mp3
Agricultural and sewage pollution can cause low-oxygen conditions and fish kills in rivers. A new study published in Nature Communications reports that hippo waste can have a similar effect in Africa’s Mara River, which passes through the world renowned Maasai Mara National Reserve of Kenya and is home to more than 4,000 hippos.

September 06, 2018 The Return Of The Bald Ibis
https://earthwiseradio.org/wp-content/uploads/2018/08/EW-09-06-18-The-Return-of-the-Bald-Ibis.mp3
The northern bald ibis, also known as the waldrapp, is a strange-looking bird with a long, curved beak, a naked head, and feathers that point straight into the air like a Mohawk haircut. In former centuries, it occurred widely in northern and eastern Africa, Asia Minor, Arabia, and parts of Europe. The ancient Egyptians considered it to be an afterworld divinity and its likeness can be seen in hieroglyphs dating back thousands of years.

September 05, 2018 Making Cities Cooler
https://earthwiseradio.org/wp-content/uploads/2018/08/EW-09-05-18-Making-Cities-Cooler.mp3
Cities are particularly miserable during heatwaves. With lots of concrete and asphalt surfaces, they soak up lots of heat and re-radiate it. Lots of tall buildings block cooling breezes. Factor in car exhaust and heat from air conditioners and it all adds up to the urban heat island effect. Cities can be several degrees warmer during the day and as much as 20 degrees warmer at night. All of this extra heat is not just a comfort issue, it is a serious health problem.

September 04, 2018 Fish And Their Sense Of Smell
https://earthwiseradio.org/wp-content/uploads/2018/08/EW-09-04-18-Fish-And-Their-Sense-Of-Smell.mp3
We use our sense of smell for all sorts of things, like locating food and habitat, avoiding danger, and so on. Fish do as well. But instead of smelling scent molecules in the air like humans do, fish use their nostrils to sense chemicals suspended in water.

August 31, 2018 Heat-Resistant Corals
https://earthwiseradio.org/wp-content/uploads/2018/08/EW-08-31-18-Heat-Resistant-Corals.mp3
All over the world, coral reefs are being wiped out by rising sea temperatures brought about by climate change. When sea temperatures get too high, the symbiotic relationship between coral polyps and microscopic algae living within the coral breaks down and the coral either digests or expels the algae. The result is coral bleaching which weakens, and if it persists, kills the coral.

August 30, 2018 An Elephant Repellant
https://earthwiseradio.org/wp-content/uploads/2018/08/EW-08-30-18-An-Elephant-Repellant.mp3
Growing human populations in Africa and Asia have created ever larger areas where elephants conflict with humans by trampling crops or causing other damage. These conflicts have occasionally been tragic when people were trampled to death and there are serious consequences when crops are destroyed. The individual elephants responsible for such destruction are often killed.

August 29, 2018 Bacteria-Powered Solar Cell
https://earthwiseradio.org/wp-content/uploads/2018/08/EW-08-29-18-Bacteria-Powered-Solar-Cell.mp3
Commercially-available solar panels are composed of solar cells that are most often made from various forms of silicon. Some panels use thin-film cells made from other semiconductor materials. Solar cells utilize a property of semiconductors that allows them to convert light energy into electrical energy.
