Professor Ashani Weeraratna has been studying the cancer microenvironment in her lab for the past 17 years. Taking into account that the tissues in our bodies change as we age is important when researching cancer biology. She hopes that gaining a better understanding of how the growth of cancer cells is affected by their direct cellular ‘neighbourhood’, especially when we age, could be key to developing better treatments for patients with cancer.

The Christmas Island red crab is of land crab that is endemic to Christmas Island and Cocos (Keeling) Islands in the Indian Ocean. Although restricted to a relatively small area, an estimated 43.7 million adult red crabs once lived on Christmas Island alone,[3] but the accidental introduction of the yellow crazy ant is believed to have killed about 10–15 million of these in recent years.[4] Christmas Island red crabs make an annual mass migration to the sea to lay their eggs in the ocean.[5] Although its population is under great assault by the ants,[6] as of 2020 the red crab had not been assessed by the International Union for Conservation of Nature (IUCN) and it was not listed on their Red List.
Travel to a land sculpted by ancient volcanoes, where crystal blue rivers carve their way through primeval forests, towering mountains give way to lush valleys and pristine lakes, and deep below the surface lie vast networks of cavernous wonders. This is the Deschutes National Forest.
The Deschutes National Forest is a United States National Forest located in parts of Deschutes, Klamath, Lake, and Jefferson counties in central Oregon. It comprises 1.8 million acres along the east side of the Cascade Range.

Periodical cicadas, identified as Brood X, are back, providing us with a once-every-17-years opportunity to witness a remarkable natural phenomenon, as these insects emerge and breed, while producing sounds as loud as a jet engine. Correspondent Chip Reid talks with entomologists about the cicadas’ cycle, and how their protein can satiate the appetites of predators (and cookie lovers).
On this Mother’s Day “Sunday Morning” takes us among sandhill cranes and their chicks in Titusville, Florida. Videographer: Doug Jensen.
The sandhill crane is a species of large crane of North America and extreme northeastern Siberia. The common name of this bird refers to habitat like that at the Platte River, on the edge of Nebraska’s Sandhills on the American Plains.
Titusville is a city and the county seat of Brevard County, Florida, United States. The city’s population was 43,761 as of the 2010 United States Census. Titusville is located along the Indian River, west of Merritt Island and the Kennedy Space Center, and south-southwest of the Canaveral National Seashore.

During a three month journey travelling and working on organic farms in Japan, filmmaker Steve Atkins often found himself distracted by the beauty around him. As sunlight filtered through the trees that towered over him, their silhouette gracing the surface beneath or ahead him, he felt repeatedly drawn and connected with the Natural world — an effect of Komorebi performing itself on the peripheries.
There is a magical quality to the animate expression of Nature; a mutual puppet-show hosted between trees, light and wind. “When I paused long enough to take it all in, to share in a humble celebration of Nature’s playfulness, I was gifted with a potent ease,” Atkins shares…
