In a discovery that could greatly reduce the size and cost of computer chips, Princeton researchers have found a fast method for printing ultrasmall patterns in silicon wafers.

The method, described in the June 20 issue of Nature, could allow electronics manufacturers to increase the density of transistors on silicon chips by 100-fold while dramatically streamlining the production process. Packing more transistors onto chips is the key to making more powerful computer processors and memory c

A new way to assemble complex, three-dimensional structures from specially formulated colloidal inks could find use in advanced ceramics, sensors, composites, catalyst supports, tissue engineering scaffolds and photonic materials.

As will be reported in the July 9 issue of the journal Langmuir, scientists have developed colloidal, gel-based inks that form self-supporting features through a robotic deposition process called robocasting. A computer-controlled robot squeezes the ink out of a s

A short course of hormone therapy appears to increase older men’s strength and may help seniors continue their everyday activities throughout the aging process, according to a study released today at the Endocrine Society’s 84th Annual Meeting.

Men over age 60 who took the androgen oxandrolone daily for 12 weeks had significantly stronger muscles in their upper and lower body than men who took a placebo, according to E. Todd Schroeder, Ph.D., postdoctoral fellow in the Department

A Medical College of Georgia researcher is tracing the pathway that leads people with hypertension to kidney damage and possible kidney destruction.

He’s found a key vasodilator that is degraded in hypertension and the potential for developing drugs that prevent organ damage in these patients.

“In every form of hypertension, except pulmonary hypertension, which is limited to the lungs, there is a change in kidney function so the kidneys cannot excrete the proper amount of sal

Patterns of genes that are active in tumor cells can predict whether patients with diffuse large B-cell lymphoma (DLBCL) are likely to be cured by chemotherapy, scientists reported today in the New England Journal of Medicine.

Researchers analyzed thousands of genes in lymphoma biopsy samples from patients with DLBCL and determined that the activity of as few as 17 genes could be used to predict patients’ response to treatment. “We’re able to reliably predict the survival of these patients

A newly established national biomedical center at Cornell University is reporting its first major advance: a new way of measuring, or “visualizing,” proteins. The new technique will hasten the transformation of the human genome project’s blueprints of life into a comprehensive view of the biochemical and physiological circuitry that interconnect to form entire organisms.

The technique, which determines the structure of a protein by measuring the distances between atoms in the molecule at g
