What it Takes to Make a Brain: Cellular diversity in cortical development

by Olubusola Olukoyafigures by Corena Loeb Our ability to take in information from the world around us, make inferences, and execute appropriate reactions is generated by our brains. The brain, which weighs about 1.5 kilograms in the average adult, takes up 20% of our body’s energy expenditure to power a network of roughly 86 billion cells. Ongoing research in the field of neuroscience utilizes various … Continue reading What it Takes to Make a Brain: Cellular diversity in cortical development

Gene Regulatory Networks: From DNA to development

by Samantha Roylefigures by Allie Elchert Have you ever thought about how a single cell can grow into a living, breathing, human? The extraordinary complexity of our thinking brains, wiggling fingers and beating hearts emerges from a single celled zygote, formed from the fusion of egg and sperm. Many of us have heard of DNA, the molecule that contains the instructions for life, but have … Continue reading Gene Regulatory Networks: From DNA to development

How Marijuana Exposure Affects Developing Babies’ Brains

As states have begun to legalize marijuana, its use has been more openly discussed. While the effects of other commonly used drugs, such as alcohol, have been studied extensively, the effects of marijuana – especially on developing babies during pregnancy – have been much less studied and less widely publicized. This relative silence from the scientific community has affected the public’s opinion on the safety … Continue reading How Marijuana Exposure Affects Developing Babies’ Brains

Make No Bones About It: Human skeletal stem cells discovered for first time

Human stem cells are specialized cells that can be harvested from the body and engineered to turn into various tissues and organs. Perhaps the greatest potential use of stem cells is the generation of new tissues for organ transplants. Unfortunately, scientists have long struggled to find skeletal stem cells that can reliably turn into bone, cartilage, and supportive tissues of the skeleton. In a study … Continue reading Make No Bones About It: Human skeletal stem cells discovered for first time

Moon and Stars

If you look closely at this zebrafish embryo, you will notice bright spots that look like stars covering the entire body. The nuclei of each cell in this embryo has been labeled with a fluorescent protein so when you look at the nuclei under a microscope, they are resplendent. By labeling each individual nuclei, we can visualize changes occurring in each cell throughout development of … Continue reading Moon and Stars
