For decades, nutritionists have been identifying and warning us about the health risks caused by “bad” foods, and offering advice about which foods we should be eating in order to be healthy. Most of these recommendations are based in research, but with new studies being conducted on a regular basis, the lists of healthy and unhealthy food options change as new data comes to light.

Trips to remote areas of the world can be fraught with peril, and even though we are aware of many of the dangers in specific regions, sometimes they can still sneak up on us. A joint expedition by the Northern Fleet, Russia's naval fleet in the Arctic, and the Russian Geographical Society (RGO) narrowly avoided injuries after a landing boat was sunk off Franz Josef Land.

Science and marketing don’t usually go together, but Neil Gemmell, a geneticist and professor at New Zealand’s University of Otago, used all of the marketing channels at his disposal to launch a new conversation about the Loch Ness monster based on his recent research findings. “I am unashamedly using the monster as a way to attract interest so I can talk about the science I want to talk about,” the told The Washington Post after publishing the results of the study conducted by his team.
A century ago, gold was the most important metal because all of the world’s currencies were based on the gold standard. This led to the international exploration and mining activities that formed the basis of the economies of countries like South Africa.

Antarctica has become a popular destination for tourists looking for extreme experiences, with some companies charging close to half a million Rand for a “luxury tour” of the world’s southernmost continent.

In an interview on The Late Show With Stephen Colbert in 2015, Elon Musk suggested detonating nuclear bombs over the poles on Mars in order to help make the red planet more liveable for the colonists Musk is planning on sending there.

From anti-oxidant bearing vitamins to the lotions and potions sold by cosmetics companies, there are numerous products on the market to help fight the signs of ageing. Until now, that was the best modern science could achieve: Fighting the signs of ageing, but not the process itself.

Sobering images recently released by NASA have illustrated the effect climate change is having on our planet. Comparing Landsat images from 1972 and 2019, it’s obvious that the branching network of glaciers that empty into Greenland’s Sermilik Fjord has changed significantly in the last 50 years.

Quantum physics studies the smallest energy levels and particles known to science. At this miniscule level, something called quantum entanglement occurs, where two or more particles become entangled and they can only be described by a quantum state for the pair or group, rather than by their individual quantum states. A quantum state includes things like position, momentum, energy, angular momentum, spin and so on.
