Are Boltzmann Brains Real?

Consider the following: a lone brain, suspended in an interminable stretch of the cosmos. It contains memories of what seems like a lifetime, hopes, and dreams, only to disintegrate into chaos a split second later.

Exoplanets: A World Outside of Our Own

Over 6,000 exoplanets have been discovered in the three decades since the first planet was discovered outside our solar system. NASA’s definition of an exoplanet is “any planet outside of our solar system.”

An Overview of CRISPR

Over the past two decades of scientific research, one significant development in biotechnology has been the transformation of CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats) into a gene-editing technology.

The Types of Prion Diseases

Prion diseases (PrDs) are triggered by misfolded proteins called prions. PrDs are neurodegenerative diseases with symptoms including brain disorder and dementia, which often ultimately lead to death.

Why Starship?

That day while in orbit, Starship 41 deployed 26 V3 Starlink satellites before reentering the atmosphere. Later, it performed a soft water landing in the Pacific Ocean somewhere north of Hawaii.

Science and Technology: Water on the Red Planet

The planet Mars holds an austere beauty in its barrenness. Its scars hint at a time when it could have harbored life when great rivers carved deep into its dusty surface. However, billions of years later it appears to be not much more than a massive red desert capped by two spans of ice. For 15 years scientists have been searching for liquid water at Mars’ poles, and finally, on July 25th, 2018, water was discovered.
