SXRF shows anthers have a craving for copper

Using micro-XRF imaging capability at F3 beamline, the research group led by Olena K. Vatamaniuk has linked the role of the micronutrient copper with pollen fertility and seed/grain yield.

DNA to RNA - more ways than one

Information encoded in our genes controls how we live and grow. As part of this complex process, DNA is transcribed to RNA, one "letter" (nucleotide) at a time, by an enzyme called RNA polymerase (RNAP).

CHESS imaging reveals how copper affects plant fertility

Technological advances making it possible to image micronutrients in plant tissues are giving Cornell scientists additional tools to develop crops that thrive in marginal soils.

Bringing bacteria's defense into focus

By taking a series of near-atomic resolution snapshots, Cornell University and Harvard Medical School scientists have observed step-by-step how bacteria defend against foreign invaders such as bacteriophage, a virus that infects bacteria.

Changing the identity of cellular enzyme spawns new pathway

A previously reported method involving standard recombinant DNA techniques and some novel design principles enabled a team of Cornell chemical engineers to make large quantities of functional integral membrane proteins simply and inexpensively – all without the use of harsh chemicals or detergents, which are typically used today.

Three receive annual Schwartz awards for life sciences

An immunologist, a molecular biologist and a plant scientist have each received awards from the Schwartz Research Fund for Women in Life Sciences, endowed by Joan Poyner Schwartz ’65 and Ronald H. Schwartz ’65.

What happens when leaves go from sink to source?

It is well known that plants, like animals, must constantly regulate and transport nutrients to survive. For example, the leaves of many plant species begin life as net nutrient sinks: that is, they rely on carbohydrates and other nutrients transported from elsewhere in the organism.
