Asthma, Genetics, and the Environment

By Emily Folk @EmilySFolk The relationship between asthma and genetics has evaded scientists for years. Researchers are still unraveling clues today, although they’ve made many advancements in making the connection. Environmental influences have become more significant in their impact, posing new challenges in treating the disease. As scientists explore ways to enhance asthma treatment, they also work to uncover its causes, hoping for more information on its relatively vague origin. How does asthma work? Asthma is an inflammatory lung disease characterized by shortness of breath, chest tightening, coughing, and wheezing.…

Genome Revelations: How Green Plants Evolved

By Jacqueline Mattos (@mattosjacq) Plants are ancestral organisms that have evolved over millions of years, leading to the broad diversity we see today. Green plants evolved from a common ancestor into approximately 450,000–500,000 species today. There are many gaps in understanding of their diversification that scientists still struggle to fill. In a recent paper published in Nature, researchers from the One Thousand Plant Transcriptomes Initiative reviewed and analyzed genomic data from 1,124 plant species and provided the most complete evolutionary relationship tree for green plants to date. Genomes, transcriptomes, and…

Proof of Evolution Is in Your DNA

Another great video from our friend Dr. Joe Hanson and the team behind the video series It’s Okay to Be Smart, brought to you by PBS Digital Studios. This time, we’re looking at the proof of evolution that’s embedded right there in our DNA. According to Dr. Hanson, “Humans are special, and we got that way thanks to evolution and natural selection. The proof is right there in our bodies! From anatomy to genes, here are some stories of how you got to be the way you are.” Evolution of…
