Protein that causes juvenile Batten disease also plays a key role in normal cell function

The aberrant protein that causes juvenile Batten disease, a fatal neurodegenerative disorder of childhood, also plays a key role in normal cell function, Duke University Medical Center researchers have found.

Researchers have discovered a possible way to distinguish lethal from localized prostate cancers

If future studies show their test -- measuring the level of activity of a signaling pathway called Hedgehog -- can predict which prostate cancers will spread, the results could revolutionize decision making processes for prostate cancer patients, the researchers say.

International research sheds light on Escherichia coli

An unprecedented picture of how bacteria latch on to human cells has been published by UK, French and US scientists. They have produced a finely detailed model of one of the tools used by some of the nastiest varieties of the stomach bug, Escherichia coli, to stick to and gain entry to host cells.

Ultra-sensitive measurement technique shows how biomolecular motors carry out essential tasks

In the human body, hundreds of different types of biomolecular motors help carry out such essential tasks as muscle contraction, moving chromosomes during cell division, and reloading nerve cells so they can repeatedly fire.

High-resolution images reveal the molecular rearrangements that rotavirus uses to break into cells

High-resolution images constructed by researchers at Children's Hospital Boston and Harvard Medical School reveal the molecular rearrangements that rotavirus – the most common cause of severe, dehydrating diarrhea and vomiting in children worldwide – uses to break into cells.

Researchers map structure of anti-cancer molecule and open the door to the creation of more effective cancer treatments

Scientists at Emory University, in collaboration with researchers at three national laboratories, have solved the structural puzzle of how an emerging class of promising cancer drugs works to halt cell division. The discovery potentially opens the door to the creation of more effective cancer treatments.

What is Telomere crisis?

Telomere crisis is an important early event in the development of breast cancer, and its occurrence can be identified with precision, according to recent findings by a team of scientists at the Department of Energy's Lawrence Berkeley National Laboratory and the University of California at San Francisco.

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.
