Metabolite discovery allows for fast plant growth
A project that uses modern biotechnology to produce plants that grow faster, are more robust and contain more protein is ongoing in Los Alamos National Laboratory's Bioscience Division. The project stems from the discovery of a naturally occurring plant metabolite that allows plants to regulate their own nitrogen metabolism rates, resulting in plants that reach peak growth more rapidly because they fix more carbon dioxide.

Building a better catalyst for bioremediation
There are only a few ways to handle toxic waste. Dump it, put it in a landfill, move it someplace else or change the contaminant into something less hazardous. Dealing with toxic waste is a major problem that is beginning to be addressed in an innovative way: using bacterial enzymes, catalytic proteins produced by living cells, to transform the waste.

Using pathogen sequence data
As scientists delve into the vast quantity of biological data currently being produced, the problems of handling such a treasure trove of information are daunting. New tools and techniques for managing, storing, analyzing, mining and visualizing this information are the focus of much attention in the scientific community, especially when the data can have a bearing on public health and even emergency response.

Optical biopsy studied as breast cancer treatment aid
Breast cancer is the leading cause of cancer-related death in women aged 40-59 and was expected to total more than 45,000 deaths in the United States last year, according to the American Cancer Society. A Los Alamos National Laboratory-developed technology, the Optical Biopsy System (OBS), may aid in not only the diagnosis of breast cancer, but the success of the surgical treatment as well.

Unmasking the mysteries of chronic beryllium disease
Beryllium is a unique lightweight metal used in nuclear weapons and, in the commercial sector, for telescope mirrors, golf clubs and a variety of other applications. While solid beryllium and beryllium alloys are safe, fine particulate beryllium is hazardous if inhaled.

'SNP'ing' away at human health issues
In the summer of 2000, scientists around the world cheered as the effort to unravel the mystery of the human genome reached a milestone—a completed draft of the human genome sequence. The sequence is a set of instructions that determines individual characteristics ranging from the cosmetic, such as hair and eye color, to the medically important, such as susceptibility to disease and response to treatments.

Molecular machines and networking
We began the 20th century with very little knowledge of the molecules of life. For the first 50 years, researchers focused largely on trying to understand molecules' make up, wondering how molecules were able to do such mysterious things as pass on hereditary information.

Bubble science benefits deep divers
Nitrogen, that colorless, odorless gas that makes up 80 percent of our air, is perfectly harmless as it's breathed in and out on land, but for underwater divers, it's the enemy.

The chemistry of life's building blocks
Life’s molecules are made up from chemical building blocks that can be synthesized in a laboratory. The ability to synthesize these molecular components is extremely important in the quest for understanding the structures and functions of the biological macromolecules, DNA, RNA and proteins.

Shaping the future
Proteins are the biological workhorses that make life possible. They provide structure, synthesize complicated chemicals, control the ability to move, help transmit neural impulses and perform countless other biological demands. Their ability to function properly is intimately tied to their structure—a complex arrangement of twists, loops, spirals and folds. Understanding this molecular origami is crucial in developing a fundamental understanding of molecular biology, designing disease-fighting drugs and repairing malfunctioning proteins.
