STAP Retraction Imminent
In January, two papers were published in the prestigious journal Nature showing how to make stem cells using a shockingly simple and completely novel approach — by putting cells in an acid bath. The resultant mouse stem cells were called STAP cells (for stimulus-triggered acquisition of pluripotency). However, since then, other researchers have had great … Continue reading
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
MERS Update: Now in the U.S.
Since it was first discovered in a person in mid-2012, MERS (short for Middle East respiratory syndrome) has been a looming viral threat. MERS is a disease caused a type of virus called a coronavirus (CoV), which typically infects the respiratory and gastrointestinal systems. (Many common colds and even cases of pneumonia are caused by … Continue reading
Biology-Related Exhibits at the Miraikan Museum in Tokyo
Note: The Biology Bytes blog will only be updated on Tuesday this week (the author is traveling in Japan). Regular Tuesday/Thursday updates will resume on June 3. Whenever I travel internationally, I make a point of visiting science museums. It’s fascinating not only to learn scientific concepts from them, but also to see what specific … Continue reading

Next week will feature a special tidbit on biology-related exhibits at the Miraikan National Museum of Emerging Science and Innovation in Tokyo, Japan, which the author will be visiting. Regular Tuesday/Thursday updates will resume on June 2. Have … Continue reading
Toxoplasma: A Common Parasite that Affects Height, Personality, and Lots More
Have you ever felt like your reaction time isn’t as good as it should be? Or, if you’re male, have you ever had people comment that you look particularly masculine? These traits might seem unrelated, but they actually can be due to the same thing — infection by a very common parasite called Toxoplasma gondii … Continue reading
Fecal Transplants and C. difficile
The bacteria Clostridium difficile is pretty terrifying — if it infects a person’s gut, it can cause severe diarrhea, bloating, and potentially death. In the U.S. alone, it hospitalizes nearly 250,000 people and kills at least 14,000 people each year. Why not just fight it with antibiotics, like we use to fight other bacterial infections? … Continue reading
Epigenetics Inherited from Mom and Dad
With Mother’s Day coming up, it can be fun to talk about some of our family’s genetic traits, like eye color, hair color, or having mid-digit hair (yup, that’s genetic too!). We all know that we get our genetics — the basic blueprints that make us who we are — from Mom and Dad, but … Continue reading
Citizen Biology
Are you not a scientist by training but you’d like to help scientists do real research? Or maybe you are a scientist and would like to aid others in doing more investigations in your spare time. Whatever your background, there are actually many ways that you can now do real scientific research in your spare … Continue reading
