Animal phobias are likely the most common type of phobias, followed by an extreme fear of heights.

Some researchers have labeled nomophobia, the fear of being without your phone, as 'the phobia of the 21st century.'

'Fear of life closes off more opportunities for us than fear of death ever does.'

Friedrich Nietzsche theorized that we will live our lives over and over again: the myth of eternal recurrence

Rather than a theory of physics, the idea is designed as a moral argument. While Nietzsche famously eschewed the Christian afterlife, he wanted to avoid the nihilism that results from no longer having such an ultimate horizon.

If not, he would argue, you're not living well.

Astrobiology is the study of life's origins and the search for life beyond Earth

The field incorporates observational missions to find and classify exoplanets—planets orbiting stars besides the sun—the probing of Earth's most extreme environments to learn what conditions allow life to exist, and theoretical and lab work to identify and analyze potential biochemical signatures.

'There cannot be mental atrophy in any person who continues to observe, to remember what he observes, and to seek answers for his unceasing hows and whys about things.'

-Alexander Graham Bell (1847-1922)

AI superintelligence is a hypothetical system vastly more capable than humans

Researchers describe superintelligence as an artificial intelligence system that exceeds human cognitive ability in every area. It is viewed as the theoretical evolution of artificial general intelligence, in which AI systems learn and have the capability of a typical human.

'Last Week Tonight' explores the risks of forever chemicals (warning: language)

Per- and polyfluoroalkyl substances (PFAS) are a group of man-made chemicals used in a wide range of products due to their unique properties. However, because they can persist in the body and environment for thousands of years, they’ve earned the moniker “forever chemicals”—and have been linked with numerous health risks.

Sleep paralysis occurs when the body fails to 'unfreeze' in sync with waking

When the body falls into a deep enough phase of sleep, it paralyzes certain parts of itself so the brain can't force it to physically act out dreams.
