At just 18 atomic mass units, water has an anomalously high boiling point compared to other molecules of similar size due to its strong hydrogen bonds. This unique property prompts the question: are there any other liquids like water, and what characteristics are essential for life as we know it?

While all life on Earth depends on liquid water, astrobiologists are expanding their search to explore what liquids can support life on other worlds. Beyond our planet, the universe offers potential alternatives from subglacial oceans to hydrocarbon lakes, challenging our traditional biases.

Over a third of the human population struggles with sugar addiction, yet nearly every cell in the human body can generate energy from alternative sources, raising a fascinating question: can life exist without sugar? The answer is more complex than a simple yes or no, depending on the type of life considered.

All living organisms, from the simplest bacteria to the most complex mammals, require a constant input of energy to sustain life. This fundamental law of biology leads to the fascinating question: could there be life without food? While the answer is complex, it reveals incredible survival strategies far beyond human experience.
