Hikes: Breitachklamm Gorge In The Allgäu, Southern Germany (8K)

The Breitachklamm is a gorge created by the river Breitach in the Allgäu region in Southern Germany. It is located at the exit of the Kleinwalsertal near Tiefenbach, a city district of Oberstdorf. It is one of the deepest gorges of the Bavarian Alps and the deepest rocky gorge of Central Europe.

Every year around 300.000 visitors walk the 2.5 km long path through the gorge. The upper entrance of the Breitachklamm is located near the Walserschanz in Austria, with limited parking space, whereas the lower one in Oberstdorf-Tiefenbach offers a visitor center and ample parking. The Breitachklamm was formed only during the last 10,000 years after the Würm ice age. Glaciers had eroded soft rocks, and hard rocks remained. When the glaciers had melted, the Breitach river had to grind its way through the hard rocks, over a distance of 2.5 km and up to 150 metres (490 ft) deep.

Nature Views: Lake O’ The Pines In East Texas (CBS)

“Sunday Morning” takes us to Lake O’ The Pines in east Texas at sunrise. Videographer: Scot Miller.

Lake O’ the Pines is a reservoir on Big Cypress Bayou, also known as Big Cypress Creek, chiefly in Marion County, Texas, USA. The reservoir also occupies a small part of Upshur and Morris Counties. The dam is located approximately 8.5 miles west of Jefferson.

Diabetes: Understanding Insulin And Islets (Video)

Type 1 and type 2 diabetes are characterized by increased blood glucose levels. They affect almost half a billion people around the globe, and this number is projected to rise as we reach the middle of the century. In most individuals, blood glucose levels are kept within a healthy range by a hormone called insulin, which is secreted by the pancreas, but this fine-tuned regulation can go wrong in type 1 and type 2 diabetes. In this animation, we lay out our current understanding of these diseases and explore active areas of research that aim to restore the body’s blood glucose control.

Nature Views: Caddo Lake, Texas-Louisiana Border

“Sunday Morning” takes us to Caddo Lake on the Texas-Louisiana border, home to a flooded forest of bald cypress and water tupelo trees. Videographer: Scot Miller.

Caddo Lake is a 25,400-acre lake and bayou on the border between Texas and Louisiana, in northern Harrison County and southern Marion County in Texas and western Caddo Parish in Louisiana.

Science: Birds Navigating With Quantum Mechanics

Some birds can sense Earth’s magnetic field, using it to navigate. But precisely how they do this has long remained a mystery. Now, researchers have confirmed that a protein found in bird eyes displays a quantum mechanical phenomenon which makes it sensitive to magnetic fields. The researchers suggest this mechanism could be behind birds’ magnetoreception abilities.

Research: Aging & Cancer Microenvironments

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.
