The science

For decades, traditional computers have followed the same principle: bits representing 0s and 1s process information through electrical circuits. But as problems become more complex—such as simulating molecules, optimizing logistics, or breaking cryptographic codes—classical computing reaches its limits. This is where quantum computing comes in.

Quantum computers harness the principles of quantum mechanics, using quantum bits (qubits) that can exist as both 0 and 1 simultaneously thanks to superposition. Qubits can also become entangled, meaning the state of one is linked to another, even at a distance. These properties allow quantum computers to perform calculations that would take classical computers thousands of years.

The Earth is undergoing rapid changes due to human activity. Rising global temperatures, melting glaciers, and extreme weather events all point to one undeniable reality: climate change is reshaping our planet. Scientists are working tirelessly to understand these changes and predict their consequences for the future.

At the heart of climate change is the greenhouse effect. Gases such as carbon dioxide and methane trap heat in the atmosphere, causing global temperatures to rise. While this effect is natural and essential for life, human industrial activity has dramatically increased greenhouse gas levels, leading to global warming.

In 2012, scientists discovered a groundbreaking tool called CRISPR-Cas9, a molecular system that allows researchers to edit DNA with unprecedented precision. What was once science fiction quickly became reality, ushering in a revolution in genetics and medicine.

CRISPR works like a pair of molecular scissors guided by RNA. It can cut DNA at a specific location, allowing scientists to remove, insert, or modify genetic material. This technology has opened possibilities for curing genetic diseases that were previously untreatable. Conditions such as sickle cell anemia, cystic fibrosis, and muscular dystrophy could one day be corrected at the genetic level.

When astronomers look at the cosmos, they see galaxies rotating, stars forming, and cosmic structures spanning billions of light-years. Yet, the visible matter—the stars, planets, and gas clouds—accounts for only a small fraction of what is actually out there. Most of the universe appears to be made of an invisible substance known as dark matter.

Dark matter neither emits nor absorbs light, making it impossible to detect directly with telescopes. Scientists infer its existence from its gravitational effects. For example, galaxies spin so quickly that, without dark matter, they should fly apart. The fact that they remain intact suggests an unseen mass is holding them together.

Artificial intelligence (AI) has rapidly transformed from a theoretical concept into one of the most powerful tools of the 21st century. While AI was initially designed to automate repetitive tasks and analyze large datasets, its potential has grown far beyond these early applications. Today, AI is being used not only in scientific research and healthcare but also in art, literature, and music. This raises an intriguing question: how will AI shape the future of human creativity?

Creativity has long been considered a uniquely human trait, tied to consciousness, imagination, and emotional depth. However, with the rise of generative AI systems, machines can now produce paintings, write stories, compose music, and even design complex structures. Some argue that these systems are not truly creative since they rely on patterns from existing human works, but others believe that AI is expanding the definition of creativity itself.
