Genes and proteins
Consider a living cell, the fundamental unit of life. Each human cell contains the entire human genome—some 35,000 genes. But only some genes are expressed within a specific cell, resulting in the production of specific proteins. The genes that turn on in a liver cell, for example, are different from the genes that are expressed in a brain cell.

Pricing programs spur growth of renewable energy technologies
"Green pricing" is an option utilities use to allow consumers to help support electrical production from renewable resources such as solar and wind. A new study by the National Renewable Energy Laboratory (NREL) identifies key factors for ensuring the success of "green pricing" programs and ranks programs nationwide for their relative effectiveness.

New findings on breast cancer reported at the annual AAAS meeting
New experimental findings by the Lawrence Berkeley National Laboratory (Berkeley Lab) cell biologist Mary Helen Barcellos-Hoff show that exposure to ionizing radiation creates a microenvironment in the tissue surrounding breast cells that can cause even nonirradiated cells and their progeny to become cancerous. The discovery suggests new and possibly more effective means for preventing breast cancer.

MAXIMA unveils high resolution picture of the early universe
New evidence derived from measurements of minute variations in the temperature of the cosmic microwave background (CMB) have produced a new diagram of sound waves in the dense early universe. The graph, called a CMB "power spectrum," not only shows a primary resonance but is consistent with two more harmonics, or peaks.

Early detection for protection
Being able to rapidly detect biological agents is among the most difficult and yet urgent tasks facing the nation. Whether the threat is from a natural outbreak or a terrorist's release of threat agents, medical treatment cannot effectively begin without first identifying the bioagent. At the same time, effective understanding and response to a biological threat requires rapid communication across the health-care system.

Protein crystallography resource at neutron research center for imaging proteins
Thanks to a $4.8 million capital commitment from the U.S. Department of Energy, Los Alamos researchers have completed a state-of-the-art neutron diffraction station at Los Alamos' Neutron Scattering Center, part of the Los Alamos Neutron Science Center, known as LANSCE. The new station went on line in December 2000.

Biologically inspired nanotechnology
Much of today's scientific revolution is taking place at the nanometer scale. There is growing recognition that an ability to design and manipulate materials at the nanoscale will allow scientists to not only improve existing materials, but also develop entirely new classes of intelligent or "smart" materials for everything from miniaturized laboratories and micro-computers to drug delivery systems. To this end, lessons from biology offer revolutionary approaches.

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.

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.

'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.
