This year I've been reading a lot about seed dormancy and while we're all hunkered down, sheltered in place during the COVID-19 pandemic, I can't help but feel there's an apt comparison to be made. Most plants don't get a lot of input on where they land as seeds, but they do have a say
Alzheimer’s disease (AD) is the sixth-leading cause of death among adults in the US. Its progression is devastating: the brain slowly deteriorates, cognitive ability degrades, and bodily functions gradually shut down. Given our aging population and the huge financial burden of care, the National Institutes of Health is expected to contribute almost $3 billion to
In recent years, it feels like we have watched parts of the world be swallowed whole by fire, painting a very apocalyptic picture of the future. Nearly 40,000 square miles in Australia were decimated by bushfires last year. California's Camp Fire displaced about 50,000 residents, and Indonesia saw over 2 million acres of land consumed
Dog coats come in a seemingly endless variety of patterns, lengths, textures and colors, determined by their genetic makeup. Just 8-14 different genes are responsible for most of these differences in coat color and pigmentation. Dogs inherit two alleles, or variations, of each of these genes, one from the father and one from the mother.
For a long time, ecologists have asked: why are there so many species? How is it possible that there can be so many species of, for example, phytoplankton that exist at the same time? They all use the same resources, like light, carbon and nitrogen, and all are prey to the same types of animals,
How many times has this happened to you before? You walk into a room–it could be one you've stepped foot in a dozen times that day, or never at all– and hesitate by the doorway. There is something about that space that is nagging at the back of your mind. You decide that, somehow, you
When you think of salt, your mind likely wanders to the last bit of food you seasoned. We all know salt improves the taste of food. However, most probably don't recognize its importance in human history or its role in agriculture. It was once lauded for economic value (hence the phrase “worth one's saltâ€), as
While I'm often left paralyzed by apple choice in Kroger, I know the breadth of options at grocery stores mask a far different reality: we've lost roughly 90% of the world's crop varieties in the past 100 years. This threat to future food security is referred to as genetic erosion and primarily attributed to the
At the Kennedy Space Center, NASA is finalizing preparations to launch the Mars 2020 rover in July. One of the aims of the Mars 2020 mission is to search for signs of past microbial life through biosignatures. Biosignatures typically present themselves in traces of nitrogen, oxygen, or methane, indicating some active life form in either
I have always wondered: why do I keep losing my phone, keys and other belongings? I have to take care of my belongings carefully especially if I am not carrying a purse with me. I'm sure other women can relate to my dilemma. The ridiculous reason is that our pants don't have pockets! Women's clothing,
What if I told you that the source code, or genomes, for many living organisms is available for free online? Would it surprise you? As of today, all genomes created by public funds are accessible to anyone in the world. Anyone with internet access, and a little bit of curiosity, can access tomes of genetic
The US Atlantic coast is a dynamic, living landscape. Georgia in particular displays a picturesque mosaic of barrier islands, salt marsh meadows, maritime forests, brackish marsh and river networks snaking up the Coastal Plain. Together, coastal habitats form a dynamic ecosystem capable of protecting the coastline, storing carbon, filtering water and providing coastal regions with
