Tracing the evolution of a drug-resistant pathogen

July 15, 2015 • ALBUQUERQUE, N.M. — To fight a pathogen that’s highly resistant to antibiotics, first understand how it gets that way. Klebsiella pneumoniae strains that carry a particular enzyme are known for “their ability to survive any antibiotics you throw at them,” said Corey Hudson of Sandia National Laboratories in California. Using...

Starving cancer instead of feeding it poison

May 13, 2015 • Simulation offers hope of killing cancers without sickening patients ALBUQUERQUE, N.M. — A patent application for a drug that could destroy the deadly childhood disease known as acute lymphoblastic leukemia — and potentially other cancers as well — has been submitted by researchers at Sandia National Laboratories, the University of...

A better prosthesis: Sandia invents sensor to learn about fit; system to make fit better

October 14, 2014 • ALBUQUERQUE, N.M. — As an amputee walks on a prosthetic leg during the day, the natural fluid in the leg shifts and the muscles shrink slightly. Now imagine the problem that poses for the fit of the prosthesis. There’s a growing need for a solution. The national Amputee Coalition says...

July 11, 2014 • ALBUQUERQUE, N.M. — Sandia National Laboratories researchers — competing in an international pool of universities, corporations and government labs — captured three R&D 100 Awards in this year’s contest. R&D Magazine presents the awards each year to researchers whom its editors and independent judging panels determine have developed the year’s...

Moly 99 reactor using Sandia design could lead to U.S. supply of isotope to track disease

June 16, 2014 • ALBUQUERQUE, N.M. — An Albuquerque startup company has licensed a Sandia National Laboratories technology that offers a way to make molybdenum-99, a key radioactive isotope needed for diagnostic imaging in nuclear medicine, in the United States. Known as moly 99, it is made in aging nuclear reactors outside the country,...

Prototype electrolyte sensor provides immediate read-outs

June 3, 2014 • Painless wearable microneedle device may reduce trips to doctors’ offices ALBUQUERQUE, N.M. — Patients trying to navigate today’s complex medical system with its costly laboratory analyses might prefer a pain-free home diagnostic device, worn on the wrist, that can analyze, continuously record and immediately remedy low electrolyte levels. Runners, athletes...

Entrepreneur teams with Sandia scientists to bring life-saving vaccines to far reaches of the world

March 25, 2014 • ALBUQUERQUE, N.M. — Getting life-saving vaccines to the most remote parts of the world is no easy feat. Biopharmaceuticals are highly sensitive to heat and cold and can perish if their temperature shifts a few degrees. “The vast majority of the world’s population lives in areas where electricity and refrigeration...

Biocavity laser is new tool in war on cancer

March 23, 2000 • ALBUQUERQUE, N.M. -- A "smart scalpel" mechanism intended to detect the presence of cancer cells as a surgeon cuts away a tumor obscured by blood, muscle and fat has been developed in prototype by scientists at the U.S. Department of Energy's Sandia National Laboratories.
SANDIA RESEARCHER Paul Gourley examines the photomask used to microfabricate the biocavity microlaser flow device.
