Moms Aren’t the Only Ones who Pass on Mitochondrial DNA

If you think way, way back to your high school biology class, you might remember a little cellular structure called the mitochondrion. Its claim to fame is that it’s the “powerhouse” of the cell — the organelle in charge of creating energy. But it also contains its own DNA, separate from the traditional DNA we think of, which lives in the nucleus of a cell. That nuclear DNA contains genetic information from both of our parents. But in mitochondrial DNA (mtDNA), that genetic information only

Strange Supernova Observation Hints at New Kind of Stellar Explosion

A Strange Supernova Astronomers studying a violent stellar explosion have witnessed a unique supernova phenomenon that’s like nothing they’ve seen before. Researchers discovered the supernova, known as ASASSN-18bt (or SN 2018oh), this past February. And, strangely, within the early stages of the stellar explosion,  researchers saw an unusual burst of light emerge. New analysis of this unique supernova could help researchers gain insight into the still-unclear process of how stars die and e

Will We See “Monstrous” Neuroscience?

The science story of the past week was the claim from Chinese scientist He Jiankui that he has created gene-edited human babies. Prof. He reports that two twin girls have been born carrying modifications of the gene CCR5, which is intended to protect them against future HIV risk. It's far from clear yet whether the gene-editing that He described has actually taken place - no data has yet been presented.  The very prospect of genetically-modifying human beings has, however, led to widespread c

However, the city of Anchorage has experienced damage from the shaking. Anchorage airport has seen disruptions as the control tower was evacuated (and is apparently running out of a truck right now). More importantly, a tsunami warning was declared for the coast of Alaska, so people are trying to evacuate the area. However, a P
