Stem Cell Awareness Day: October 8, 2014
Tomorrow, Wednesday, October 8, is Stem Cell Awareness Day. It’s a day to celebrate stem cells, have discussions on what stem cell research is, and learn about potential benefits and disease treatments using stem cells. Many national and international events (especially in California) are taking place to celebrate this special day — the California Institute … Continue reading
The Science of ALS and the Irony of the Ice Bucket Challenge
With the ALS ice bucket challenge going viral, amyotrophic lateral sclerosis (ALS) has been getting a lot of attention. But what exactly is ALS?

Our Microbiomes: In Sickness and in Health
Last week, we took a look at the amazing diversity of microbes (bacteria, fungi, and others) that live on, and inside of, our bodies.

Two New Drugs to Fight Antibiotic-Resistant Bacteria
Because they help us fight bacterial infections, antibiotics are an amazing invention that has let us greatly improve our quality of life and life expectancy. However, their overuse has led to some extremely dangerous pathogens — antibiotic-resistant bacteria. Specifically, last fall it was found that more than 2 million people in the U.S. get infected … Continue reading
Stem Cell Trials to Treat Spinal Cord Injuries
While human embryonic stem cells (hESCs) were originally created in 1998, it wasn’t until 2009 — over a decade later — that they were approved by the FDA for use in a clinical trial in people. It was a long wait, but the trial was quite the promising one. The clinical trial, undertaken by the … Continue reading
