Leaf senescence is a developmental program in which nutrients are recycled from leaves at the end of their lifespan. In annual plants, these recycled nutrients often support seed development. In deciduous trees, the nutrients can be stored in Autumn to support the growth of new tissues in the Spring. Thus leaf senescence is of great practical value to plants, and the cover photograph of a maple tree by Jordan Hall at Indiana University illustrates the aesthetic value of this process. To further understand this nutrient-recycling program at a molecular level, Bhalerao et al. (pp. 430-442)...

Fat cells may hold the key to predicting type 2 diabetes, a major cause of kidney failure, limb amputations, blindness, heart disease and stroke.

The disease, also called adult-onset diabetes, affects 8 percent of the U.S. population age 20 or older. While more than 80 percent of diabetics are overweight, only 10 percent of obese individuals develop the disease. Knowing your risk is a key to prevention.

Knowing what to expect: "Currently, we have no markers to tell who among these overweight individuals is going to become diabetic," says Alan Attie, a College biochemist who...

The award, provided by funds given in memory of Dr. Leirmo by her husband, consists of $250, and will be awarded at the departmental poster session on February 7. The award is designated for a graduate or postdoctoral student who best exemplifies the spirit of Sigrid Leirmo, who received her Ph.D. degree in the Department of Biochemistry in 1989 and was a postdoctoral research associate in the Department of Bacteriology when she died tragically in an accident in October 1990. Dr. Leirmo was widely acknowledged among her fellow students and colleagues both as a promising researcher and as...

John Suttie, emeritus professor of biochemistry at the College of Agricultural and Life Sciences, has received the 22nd annual Bristol-Myers Squibb/Mead Johnson Award for Distinguished Achievement in Nutrition Research. He was honored for outstanding experimental work that has defined the molecular action of vitamin K and its function in blood clotting. Suttie accepted the award Oct. 10 in Madison, following a symposium held in his honor on vitamin K-dependent proteins and their clinical use.

A novel form of vitamin D has been shown to grow bone in the lab and in experimental animals, a result that holds promise for the estimated 44 million Americans, mostly post-menopausal women, who suffer from or are at risk for the bone-wasting disease osteoporosis.

The research, conducted by a team of scientists led by biochemist Hector F. DeLuca at the University of Wisconsin-Madison, was reported this week (Sept. 30) in the Proceedings of the National Academy of Sciences (PNAS), a leading scientific journal.

By subtracting a single gene from the genome of a mouse, scientists have created an animal that can eat a rich, high-fat diet without adding weight or risking the complications of diabetes, according to a new study published this week.

Writing in the online editions of the Proceedings of the National Academy of Sciences (PNAS), James M. Ntambi, a professor of biochemistry and of nutritional sciences at the University of Wisconsin-Madison and colleagues report that mice lacking a gene known as SCD-1 can eat a rich high-fat diet and avoid the consequences of fat deposition and excess...
