Archaeologists discovered a circle of deep shafts 3km from Stonehenge. The discovery is considered the largest prehistoric structure ever found in Britain.

The structure, that surrounded the settlement of Durrington Walls, consists of a 2km wide circle of large shafts measuring more than 10 meters in diameter by 5 meters depth and was excavated more than 4,500 years ago.

A team of researchers at POSTECH, Pohang University of Science and Technology, developed a smart contact lens technology for "both continuous glucose monitoring and treatment of diabetic retinopathy". The contact lenses were tested on diabetic rabbits and were able to measure glucose levels in tears that matched their blood glucose levels. The team has also confirmed that the technology could trigger the release of drugs encased in the contact lenses to treat diabetic retinopathy.
