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 »

First Transplant using Induced Pluripotent Stem Cells: Treating Blindness

Induced pluripotent stem cells (iPSCs) have enormous potential for being used in tissue transplants and therapies. Why is this? It’s because iPSCs can be made using virtually any cells from a person’s body — such as skin or fat samples that wouldn’t be missed. (And since they’re the patient’s own cells, the immune system should … 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? It is essentially a poorly understood neurodegenerative disease that kills relatively quickly — with people usually dying within 3–5 years after onset of the first symptoms — and is responsible for … Continue reading »

The Hobby Lobby Ruling: Contraceptives and Abortifacients

Last week, the Supreme Court ruled that, due to religious objections, Hobby Lobby (and other for-profit companies) does not have to provide health insurance coverage for contraceptives that are part of the Affordable Care Act. Specifically, Hobby Lobby objected to four contraceptive methods – Plan B, Ella, and two intrauterine devices (IUDs) – because Hobby … Continue reading »

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 »

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 »

The Latest on the STAP Controversy

Back in late January, two papers were published in the prestigious journal Nature showing a completely novel and shockingly simply way to make stem cells – the approach used an acid bath. Since then, there’s been huge controversy surrounding the creation of these mouse stem cells, called STAP cells (for stimulus-triggered aquisition of pluripotency). This … Continue reading »

How a Substrate Affects a Stem Cell’s Fate

Much of the stem cell field is devoted to figuring out how to direct what stem cells turn into. (In stem cell terminology, the process of having a stem cell become a different type of cell is called differentiation.) By better controlling a stem cell’s fate, we can more efficiently turn the cell into a … Continue reading »

Using Electricity to Heal Wounds

When we get a cut, or a small bruise, the healing process may seem simple — our body knows how to seal up the cut, and repair the bruised tissue over time — but there’s actually a lot that goes into fixing up an injury. For example, cells have to move to the right location, … Continue reading »

Reaching K-12: Biology-Related Science Fair Project Ideas

Doing a science fair project can be very daunting, especially for a child who’s never done one before. To help out the burgeoning biologist (or parent of a biologist-to-be), here we’ll explore some great biology-based science fair project ideas provided by Science Buddies. And since deadlines for many fairs are quickly approaching, we’ll focus on … Continue reading »
