How many oranges can you fit in a box? Mathematicians are obsessed with perfecting their answer to this question in not just our familiar three-dimensional world, but in higher and higher dimensions beyond it. For several decades, they've made only minimal progress toward finding ... Show More

A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible.The story How Undergraduate Upends a 40-Year-Old Data Science Conjecture first appeared on Quanta Magazine. 

As far as we know, quantum mechanics is a universal theory that explains matter and light more or less perfectly. It shows us why atoms don't collapse and why electrons don't spiral into the nucleus of the atom. It explains why glass is clear, why grass is green, why the sky is b ... Show More

In this episode, we explore the different phases of the cell cycle: Interphase (G1, S, G2) and the M phase (mitosis). Next, we discuss the regulation of the cell cycle and the key checkpoints that ensure its proper progression. Finally, we touch on how dysfunction in the cell cyc ... Show More

The electron transport chain is a fundamental pathway in biochemistry, critical for understanding the energy production that powers cellular function. In this episode, guest host Alex Starks breaks down the intricate process of the electron transport chain (ETC). Building on prev ... Show More

At first, life on Earth was simple. Cells existed, functioned and reproduced as free-living individuals. But then, something remarkable happened. Some cells joined forces, working together instead of being alone. This transition, known as multicellularity, was a pivotal event in ... Show More

One of the body's key survival mechanisms is gluconeogenesis, a vital metabolic process, and the body's clever way of making glucose when supplies are low. On this episode of the MCAT Basics podcast, guest host Alex Starks walks through the process of gluconeogenesis. He explains ... Show More

In this episode of MCAT Basics, we’ll cover Electrochemistry. We start with the role of salt bridges in electrochemical cells and cover the intricacies of cell notation. We’ll also discuss how ions maintain charge balance, the importance of reduction and oxidation potentials, and ... Show More

Le Soleil, comme toute étoile, traverse plusieurs phases de vie marquées par des changements dans son noyau et son enveloppe, dictés par les processus de fusion nucléaire. Ces étapes sont déterminées par la masse de l’étoile, qui contrôle les types de réactions nucléaires possibl ... Show More

Guest: Dr. Filipe Pereira is an Associate Professor at the Lund Stem Cell Center at Lund University. The Pereira lab studies how hematopoietic cell fate is specified, maintained, and eventually modified or reversed. Inspired by the fields of stem cell biology, immunology, and can ... Show More

In this episode, we’ll explore the distinct characteristics of prokaryotic cells and what sets them apart from more complex cell types. We’ll discuss the presence of plasmids—small DNA rings that enable genetic information exchange. We’ll examine how prokaryotic cells lack membra ... Show More

In 2022, the Nobel Prize in Chemistry went to Dr. Carolyn Bertozzi of Stanford University, Dr. Morten Meldal of the University of Copenhagen, and Dr. K. Barry Sharpless of the Scripps Research Institute “for the development of click chemistry and bioorthogonal chemistry.” In “cli ... Show More

In this episode, we focus on biosignaling and cover how cells communicate through systems like voltage-gated and ligand-gated ion channels, using real-world examples such as neuronal signaling and muscle contraction. We also break down the role of enzyme-linked receptors, specifi ... Show More
