A Near Perfect Solution to a Decades-Old Biology Problem

by Sebastian Rowefigures by Jovana Andrejevic First conceptualized in the 1960s, the protein folding problem – how to predict a protein’s structure from its sequence – has been one of the main concerns of structural biologists worldwide. Last year Google’s DeepMind, a team of programmers studying artificial intelligence, claimed to have the solution; much in the same way they solved the board game Go in … Continue reading A Near Perfect Solution to a Decades-Old Biology Problem

3D printed corals grow algae that photosynthesize more efficiently

Central to coral reefs around the world is the deeply interdependent relationship between corals and algae. This interconnection is responsible for algae’s protected habitat, corals’ bright colors, and the mutual exchange of nutrients for photosynthesis. Algae growth is modulated by a process called self-shading, decreasing exposure to light. In an artificial setup, however, this process prevents researchers from growing coral quickly. To prevent this light … Continue reading 3D printed corals grow algae that photosynthesize more efficiently

All Wound Up: DNA sequencing reveals the 3D structure of our DNA

by Gemma Johnson figures by Olivia Foster You might remember being in a biology class where molecular biology is often represented by cartoons in bright colors on the pages of a textbook. What’s happening inside our cells, however, is much more complicated than what’s depicted in those caricatures. The DNA molecules that constitute our genetic code look like a twisted ladder (the formal name is … Continue reading All Wound Up: DNA sequencing reveals the 3D structure of our DNA
