New Covid test gives results comparable to PCR test in just 5 minutes

Researchers at the Nanyang Technological University (NTU) in Singapore have conducted a study investigating a new prototype breathalyzer test that detects a Covid infection through changes in your chemical “breath print”. To use the breathalyzer, the user breathes into a single-use tube for Read More...

Nature's Giants- Icebergs in Greenland, under summer’s permanent daylight. What we see often is only a fractional part of what it really is. The whole truth is often hidden from view.

Submarine to explore the underside of Greenland’s glaciers in a first

Scientists are desperately trying to save the world’s glaciers. As they hold a large amount of water and carbon dioxide, it is essential that we slow the demise of these structures for the climate's sake. We’ve previously written about a group using special mountain blankets on Mount Titlis Read More...
