Most agronomists look to their laboratories, greenhouses or research farms for innovative new cropping techniques. But Jane Mt. Pleasant, professor of horticulture and director of the American Indian Program at Cornell University, Ithaca, N.Y., has taken a different path, mining her Iroquois heritage for planting and cultivation methods that work for todays farmers.
Mt. Pleasant studies what traditionally are known as the "three sisters": beans, corn and squash. These staples of Iroquois cropping are traditionally grown together on a single plot, mimicking natural systems in what agronomists call a polyculture. Though the Iroquois technique was not developed scientifically, Mt. Pleasant notes that it is "agronomically sound." The three sisters cropping system embodies all the things needed to make crops grow in the Northeast, she says.
She presented her work today (Feb. 15) at the annual meeting of the American Association for the Advancement of Science (AAAS) in Seattle. The talk, "Polycultural Cropping Systems From an Indigenous Perspective: Using Iroquois Worldview to Understand the Three Sisters," was part of a symposium on research methods in native science. This is the second year that such a symposium has been held at the AAAS.

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.
Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...
Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers
Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...
Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.
At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
3-D shape acquisition using water displacement as the shape sensor for the reconstruction of complex objects
A global team of computer scientists and engineers have developed an innovative technique that more completely reconstructs challenging 3D objects. An ancient...
Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
