By isolating mechanical and biological variables one by one in vitro, a team of researchers led by Prof. David Mooney, identified a possible mechanism by which normal cells turn malignant in mammary epithelial tissues, the tissues frequently involved in breast cancer.
After two years of effort, researchers led by Prof. Donhee Ham successfully measured the collective mass of ‘massless’ electrons in motion in graphene. Graphene is a one-atom-thick carbon sheet that has taken the world of physics by storm, in part because its electrons behave as massless particles. The research could provide a basis for the creation of miniaturized circuits with tiny, graphene-based components.

The demonstration shows the potential to quickly and cheaply build sophisticated machines that interact with the environment, and to automate much of the design and assembly process.
For the third summer, SEAS offered a free Science & Cooking program for kids, taught by Harvard researchers and local award-winning chefs. Students in the 4th through 6th grade from Cambridge and the surrounding communities learned about cooking techniques and how to connect food and cooking with science and math concepts.
Led by Prof. David Weitz, a team of applied physicists and cell biologists demonstrated a way to quantify the aggregate forces felt by particles and organelles in the cell, raising a host of new questions about cellular dynamics and providing a robust new tool for future investigations.

A technique developed in Prof. Federico Capasso’s lab coats a metallic object with an extremely thin layer of semiconductor, just a few nanometers thick. Although the semiconductor is a steely gray color, the object ends up shining in vibrant hues. That's because the coating exploits interference effects in the thin films. Carefully tuned in the laboratory, the coatings can produce vivid colors using the same two metals, applied with only a few atoms' difference in thickness.

A new type of lens created in the lab of Prof. Federico Capasso was a major leap forward in the field of flat photonics. The device is an ultra-thin, completely flat optical component made of a glass substrate and tiny, light-concentrating silicon antennas. Light shining on it bends instantaneously, rather than gradually, while passing through. The bending effects can be designed in advance, by an algorithm, and fine-tuned to fit almost any purpose.
