Ancient pollen may determine where clay army was made - The 2,200 year old clay army was created to protect the tomb of the first emperor of China. Where these figures were made has been a long-standing mystery. Now, pollen grains found in the clay may be used to determine the location of the ancient kilns.

Bacterial virus gene confers disease resistance in tall fescue grass – Researchers from North Carolina State University found that expressing a gene from a bacterial virus in turf grass confers resistance to two major forms of fungal disease. The bacterial virus gene encodes a protein that destroys fungal cell walls. The finding may allow for disease resistance improvements in other crops.

Global map of plant diversity – Researchers from University of California-San Diego (UCSD) have generated a map depicting the level of plant diversity across the world. The map allows scientists to estimate levels of diversity in un-surveyed regions and to pinpoint areas in need of conservation or exploration. The paper appears in an upcoming issue of Proceedings of the National Academy of Sciences.
