With a three-year grant from NASA, a Cornell chef, nutritionist, food and biological engineer and vegetarian cooking teacher are collaborating to develop and test tasty, nutritious and economical recipes that astronauts can prepare from a limited set of 15 to 30 crops grown in future space habitats. Wheat and potatoes are the staples to be complemented with rice, soy and peanuts, salad crops and fresh herbs, all to be grown hydroponically in artificially lit, temperature-controlled space farms. "Our goal is to develop a database of food-processing information and a menu of at least 100 primarily vegetarian recipes of familiar and new menu items based on crops raised in a bioregenerative life support system," said Jean Hunter, associate professor of agricultural and biological engineering at Cornell who is heading up the project. The team also is developing a food-related decision-making strategy for NASA to use in bioregenerative life support systems for multiyear missions such as a lunar scientific colony or Martian surface exploration. Bioregenerative life support, in which plants and microorganisms regenerate air, water and food for the crew, is envisioned for long-term space exploration, starting 15 to 20 years from now. "Because the cost of transporting food for these missions will be astronomical, only about 15 percent of calories will be from Earth-made foods," added David Levitsky, professor of nutritional sciences and of psychology at Cornell who also is working on the project. "Food plays a critical role in the overall psychological well-being of isolated crews." For more information, contact Susan Lang, (607) 255-3613.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
Researchers at MIT and Sandia National Labs have observed a reaction in lithium-air batteries that could help improve the design of these cells for electric vehicles and other applications.
Healthcare might seem to be an unlikely target application for the Internet of Things technology, but recent developments show small ways that big-data is going to make an impact on patient care moving into the future.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
