Yams are a staple food in West Africa, which produces over 90% of the world s yams each year. Yams play a key role in the food security, economic income, and traditional culture for the region.
While they are commonly assumed to be the same as sweet potatoes in the U.S., yams are a completely different plant. The yam tubers are much starchier and drier compared to sweet potatoes. Yams are native to Africa and Asia, and most Americans have never had a true yam.

Overview:
A color illusion that strongly induces color contrast effect has been found by a research team at the Toyohashi University of Technology Department of Computer Science and Engineering, and Electronics-Inspired Interdisciplinary Research Institute (EIIRIS). The powerful visual illusion clarified a century-old contradiction relating to simultaneous color contrast theory. Through a human psychophysical experiment, the team demonstrated that the presence or absence of flanking contours formed from extremely thin white lines could be used to switch between contradictory visual phenomena (Figure 1), enabling consistent explanation for both discrepant theories. This solution alters theories of visual computatio

Jointly organised by the United Nations University and the Japan Society for the Promotion of Science (JSPS), the
JSPSâUNU Postdoctoral Fellowship Programmeis designed to provide promising, highly qualified, young researchers with the opportunity to conduct advanced research in sustainability in co-operation with host researchers at Japanese universities and research institutions.
The UNU Institute for the Advanced Study of Sustainability (UNU-IAS, Tokyo) acts as the nominating authority for the JSPSâUNU Postdoctoral Fellowship Programme. This fellowship is aimed at candidates who have completed their doctorates in the past six years and also have professional and/or research experience. UNU-IAS will assist in securing acceptance from host researchers for shortlisted candidates.
This image of Saturn s icy, geologically active moon Enceladus was acquired by NASA s Cassini spacecraft during its October 2015 flyby. Enceladus hides a global ocean of liquid salty water beneath its crust and might also have hydrothermal vents not unlike the hydrothermal vents that dot the ocean floor here on Earth.

New research led by the American Museum of Natural History and funded by NASA identifies a process that might have been key in producing the first organic molecules on Earth about 4 billion years ago, before the origin of life. The process, which is similar to what might have occurred in some ancient underwater hydrothermal vents, may also have relevance to the search for life elsewhere in the universe. Details of the study are published this week in the journal

Cells replicate their genetic material and divide into two identical clones, perpetuating life until they don’t. Some cells pause or are intentionally made to pause in the process. When the cell resumes division after such a pause, a displaced nucleus an essential part of cell survival can become caught in the fissure, splitting violently and killing both cells. But that is not always the case; some mutant cells can recover by pushing their nucleus to safety. Researchers from Hiroshima University in Japan are starting to understand how in the first step toward potential cell death rescue applications.
