Cancer patients have the highest probability of recovering if tumors are completely removed. However, tiny clusters of cancer cells are often difficult for surgeons to recognize and remove. A new camera technology makes hidden tumors visible during an operation.

Tumor removal surgeries pose a great challenge even to skillful and experienced surgeons. For one thing, tumor margins are blending into healthy tissue and are difficult to differentiate. For another, distributed domains of cancer and pre-malignancies are difficult to recognize. Up to now, doctors depend exclusively upon their trained eyes when excising pieces of tumors. In future, a new special camera system can help visualize during operation even the smallest, easy-to-overlook malignant pieces of tumor and thereby support the surgeons during complicated inter- ventions.

Cell Circuits Remember Their History

Engineers at MIT have developed genetic circuits in bacterial cells that not only perform logic functions, but also remember the results. (Credit: Liang Zong and Yan Liang)

MIT engineers have created genetic circuits in bacterial cells that not only perform logic functions, but also remember the results, which are encoded in the cell’s DNA and passed on for dozens of generations. Read More →

A Look at Technocapitalism

Capitalism and socialism have been the primary economic theories that nations have modeled themselves after in the modern era. Throughout history, other economic models have also been used. Feudalism and various forms of command economies have defined much of the human experience. Trade and barter systems were used by the most primitive societies. However, continued exploration of space and the development of new machines might lead to the rise of societal technocapitalism. Read More →
