by Piyush Nandafigures by Corena Loeb Around 600 million years ago, single-celled life transitioned to multicellular life forms, begetting a paradigm shift in the definition of life on earth. This was an event so remarkable in earth’s timeline that it would set the stage for the evolution of complex organisms, from sponges to the human body we each reside in. These complex life forms eventually … Continue reading Grand Evolutionary Transitions: The eruption of multicellularity
Songbird migration paths are shifting due to global changes in temperature. Continue reading Changing Course: Climate Change Leads Songbirds to Reverse Migration Routes
Scientists harness embryonic cells to enhance adult lizard tail regeneration. Continue reading Embryonic Cells Help Lizards Regenerate Tails
by Alex Yenkinfigures by Allie Elchert Long before the completion of the Human Genome Project, scientists knew that many common diseases had a genetic component. However, there was debate about the architecture of these genetic effects: were there a few high-effect mutations or thousands of tiny effect mutations spread throughout the genome? Now, in the full swing of the genomics revolution, we can see that … Continue reading Mining DNA for Disease Prediction: The polygenic risk score
by Lauren Granatafigures by Xiaomeng Han As Covid-19-related deaths overwhelmed the country in 2020, drug overdose deaths furtively took their own toll. The opioid epidemic is still surging, but a new Rhode Island law aims to combat the problem through harm reduction. Instead of fixating on sobriety-centered treatment, the primary function of the new law is to protect people from infection and overdose. What are … Continue reading Reframing Opioid Addiction Treatment: What is harm reduction all about?
Scientists have discovered another piece in the puzzle of how tabby cats get their stripes. Continue reading What Makes a Cat a Tabby?
Asexual species do not have genetic variability like humans, and most animals, do. Despite that, they can still adapt to environmental changes using modifications to their DNA known as epigenetic changes. Continue reading Asexual Species Can Adapt to their Environment Even Without Changing their DNA
Researchers have grown a miniature brain that also develops eye-like structures. Continue reading Development in a Dish: Scientists Grow a Combined Brain and Eye Organoid
Animals frightened by a close call with a predator eat less and produce fewer offspring in the future. Continue reading Frightening Interactions with Predators Have Long-Term Impacts on Animal Brain and Behavior
