Science: Reviving Retinas, Floral Chocolates, First Life From RNA + Proteins

Reviving retinas to understand eyes

Research efforts to learn more about diseases of the human eye have been hampered as these organs degrade rapidly after death, and animal eyes are quite different to those from humans. 

To address this, a team have developed a new method to revive retinas taken from donors shortly after their death. They hope this will provide tissue for new studies looking into the workings of the human eye and nervous system.

10:54 Did life emerge in an ‘RNA world’?

How did the earliest biochemical process evolve from Earth’s primordial soup? One popular theory is that life began in an ‘RNA world’ from which proteins and DNA evolved. However, this week a new paper suggests that a world composed of RNA alone is unlikely, and that life is more likely to have begun with molecules that were part RNA and part protein.

Montana Views: Red Fox Kits In Paradise Valley

“Sunday Morning” shows us a vixen with her paws full, in Paradise Valley, Montana. Videographer: Judith Lehmberg.

Red fox are found throughout Montana. They can make their home while following their food source. Foxes use their nose to find prey, and then quickly pounce, much like a house cat. Spotting a red fox in Montana is never difficult if you look carefully?just keep a close watch for the bushy tail.

Science: Microbial Meat, Saltwater Crocodiles, Mosquito’s Sense Of Smell

How a move to microbial protein could affect emissions. It’s well understood that the production of meat has large impacts on the environment. 

This week, a team show that replacing 20% of future meat consumption with protein derived from microbes could reduce associated emissions and halve deforestation rates.

10:47 The neurons that help mosquitoes distinguish smell

Female Aedes aegypti mosquitoes strongly prefer human odours to those of animals, but how they distinguish between them is not well understood. Now, researchers have shown that human odours strongly activate a specific area in the brains of these insects, a finding that could have important implications for mosquito-control strategies.

Waterfall Views: Reedy River In South Carolina

“Sunday Morning” takes us under waterfalls on the Reedy River near Greenville, South Carolina. Videographer: Kevin Kjergaard.

The Reedy River is a tributary of the Saluda River, about 65 miles long, in northwestern South Carolina in the United States. Via the Saluda and Congaree rivers, it is part of the watershed of the Santee River, which flows to the Atlantic Ocean.

Nature: A Great Horned Owl Chick In Florida

“Sunday Morning” takes us to Titusville, Florida, where a great horned owl chick is being cared for by Mom and Dad. Videographer: Doug Jensen.

Great horned owls are usually 18 – 25 inches tall, have tall ear tufts, and large yellow eyes. Their size, ear tufts, and eyes make them easily recognizable when seen during daylight hours.

They are found throughout Florida and roost in large, messy nests, in tall trees. The female is larger than the male, but the male has a larger and deeper voice box.

Preservation: Cairngorms National Park, Scotland

“When it comes to climate change, scale is essential. We need to be scaling up our work and being really bold and ambitious, and that’s exactly what Cairngorms Connect is.” Find out how Scotland’s largest landscape-scale restoration project is fighting back against climate change in our new film for Cairngorms Connect.

Cairngorms National Park is a national park in northeast Scotland, established in 2003. It was the second of two national parks established by the Scottish Parliament, after Loch Lomond and The Trossachs National Park, which was set up in 2002. The park covers the Cairngorms range of mountains, and surrounding hills. Already the largest national park in the United Kingdom, in 2010 it was expanded into Perth and Kinross.

Roughly 18,000 people reside within the 4,528 square kilometre national park. The largest communities are Aviemore, Ballater, Braemar, Grantown-on-Spey, Kingussie, Newtonmore, and Tomintoul. Tourism makes up about 80% of the economy.[4] In 2018, 1.9 million tourism visits were recorded. The majority of visitors are domestic, with 25 per cent coming from elsewhere in the UK, and 21 per cent being from other countries.

North Carolina Views: Elk In Great Smoky Mountains

“Sunday Morning” takes us among the elk and turkeys at the Great Smoky Mountains National Park in North Carolina. Videographer: Scot Miller.

Elk are the second-heftiest members of the deer family, after the bigger and darker-haired moose. While there’s really no mixing up those two giant deer, the names are definitely a cause for confusion from an international perspective. In Europe, what North Americans call moose are known as “elk.” The word “moose” is an indigenous North American (likely Algonquin) word, and in New England, early European colonists distinguished between the “black moose”—the moose as we know it today—and the “grey moose,” or elk.
