Automated science speeds solution of Human Genome data

Scientists in Argonne's Biosciences Division are automating and accelerating the complex processes that coax a protein to reveal its structure so they can learn the role Nature assigned it.

New fluorescent dye technique may provide new insight into how cancerous tumors begin and grow

A technique developed by University of California, San Diego biologists, which uses bright fluorescent dyes to reveal the activity of genes in individual cells of an organism, promises to be a boon to developmental biologists, and may provide new insight into how cancerous tumors begin and grow.

Experimental vaccine against ricin

Scientists have developed an experimental vaccine against ricin, a potential biological threat agent, which fully protected mice from aerosol challenge with lethal doses of the toxin.

Successfully cloning mice from an advanced melanoma cell

Nature can reset the clock in certain types of cancer and reverse many of the elements responsible for causing malignancy, reports a research team led by Whitehead Institute Member Rudolf Jaenisch, in collaboration with Lynda Chin from Dana Farber Cancer Institute.

New screening technique to look for genes that change patients' responses to cancer drugs and other medications

Scientists have developed a new screening technique to help them look for genes that change patients' responses to cancer drugs and other medications.

First-of-its-kind noninvasive imaging technique shows two proteins interacting

Radiologists at Washington University School of Medicine in St. Louis have developed a first-of-its-kind noninvasive imaging technique that allows them to watch two proteins interacting in live animals.

Scientists create mice that don't gain weight, even when fed fat-laden, high calorie diets

By altering the expression of a single -- albeit different – gene, Drs. Roger Davis (UMASS Medical School, USA) and Ying-Hue Lee (Academia Sinica, Taiwan) have succeeded in creating two different strains of transgenic mice that don't gain weight, even when fed fat-laden, high calorie diets.

Scientists have produced a prion protein that can trigger the development of a neurological disorder similar to "mad cow" disease

Scientists have produced a prion protein that can trigger the development of a neurological disorder in mice that is similar to "mad cow" disease, according to a new study supported by the National Institute on Aging, a part of the National Institutes of Health.

A prototype microscope that uses neutrons instead of light to "see" magnified images

A prototype microscope that uses neutrons instead of light to "see" magnified images has been demonstrated at the National Institute of Standards and Technology. Neutron microscopes might eventually offer certain advantages over optical, X-ray and electron imaging techniques such as better contrast for biological samples.

Identification of PIK3CA as an oncogene associated with brain cancers opens the door to new screening processes

Hotspots in two areas of a gene that encodes a specific signaling enzyme, or kinase, are vulnerable to a variety of mutations found in five types of brain cancers, according to a report published in the August 1 issue of the journal Cancer Research.

Scientists discover genetic make-up of acne vulgaris

German scientists at the Gottingen Genomics Laboratory have discovered the genetic make-up of acne vulgaris. Acne vulgaris is a follicular disorder that affects susceptible pilosebaceous follicles, primarily of the face, neck, and upper trunk, and is characterized by both noninflammatory and inflammatory lesions.

Important step in understanding the genetic mechanisms of aging

Scientists have rendered the first gene and protein networks of human aging, an important step in understanding the genetic mechanisms of aging. The work led by Joao Pedro de Magalhaes from Harvard Medical School is detailed in the July 30 issue of FEBS Letters.
