Harvard study explores genetics behind evolution of flightless birds

Based on an analysis of the genomes of more than a dozen flightless birds, including an extinct moa, a team led by Harvard researchers found that while different species show wide variety in the protein-coding portions of their genomes, they appear to turn to the same regulatory pathways when evolving flight loss.

Harvard scientists develop way to identify topological materials

Though they have unusual properties that could be useful in everything from superconductors to quantum computers, topological materials are frustratingly difficult to predictably produce. To speed up the process, Harvard researchers in a series of studies develop methods for efficiently identifying new materials that display topological properties.

At Harvard, shark researcher documents surge of great whites off Cape Cod

For the past decade, scientist Greg Skomal and a team of researchers have been tagging and studying great white sharks off the Massachusetts coast. He hopes his work tracking the sharks’ movement, biology, and behavior will help shed light on the giant predators, help protection efforts, and perhaps reduce their encounters with humans.

Exercise, fasting shown to help cells shed defective proteins

A new study from the Blavatnik Institute finds that intense exercise and fasting activate hormones that boost cells’ capacity to dispose of defective proteins, which clog up the cell, interfere with its functions, and, over time, precipitate diseases including neurodegenerative conditions such as ALS and Alzheimer’s.
