Stem cells can preserve and improve vision in eyes damaged by retinal disease

"These findings hold great promise for potential treatments for people suffering from macular degeneration, diabetic retinopathy and other retinal diseases," says Michael Young, PhD, an assistant scientist at Schepens Eye Research Institute and the lead author of the study.

Researchers attempt to quantify processes underlying cell heterogeneity

Combining the latest methods in gene splicing and computer modeling, Rice University researchers are trying to develop a predictive framework for one of the most basic and complex biological phenomena — cellular heterogeneity, or the ability of genetic clones to act and behave differently when exposed to the same set of environmental stimuli.

New molecular tool to pinpoint DNA mutations among thousands of cells

Scientists have designed a new molecular tool, dubbed "LigAmp," to pinpoint DNA mutations among thousands of cells, the equivalent of searching for a single typo in an entire library of books.

Australian platypus research has implications for understanding the evolution of human sex determination

The mystery surrounding sex determination of the unique Australian platypus has yielded a surprising secret: it has 10 sex chromosomes.

Calorie restriction prevents certain aging-related changes in the brain

Severe calorie restriction prevents certain aging-related changes in the brain, including the accumulation of free radicals and impairments in coordination and strength, according to a mouse study at Washington University School of Medicine in St. Louis.

Research shows brain cells move like a two-stroke engine

Following the often-quoted advice of Yogi Berra — "You can observe a lot by just watching" — Rockefeller University scientists show that nerve cells in the developing brains of humans and other mammals move in a two-part "step" led by a structure within the cell called the centrosome.

Robotic microscope shows how mutant Huntington's disease protein affects neurons

Using a specially designed robotic microscope to study cultured cells, researchers have found evidence that abnormal protein clumps called inclusion bodies in neurons from people with Huntington's disease (HD) prevent cell death.

Researchers have identified a protein in the inner ear that translates sound into the nerve impulses used by the brain

Researchers at Harvard Medical School and their colleagues report in the October 13 Nature advanced on-line edition that they have identified a protein deep in the inner ear that they believe translates sound into the nerve impulses used by the brain.

Bionanotechnology that combines the strengths of nanotechnology and biochemistry to generate a new type of bionanomaterial

A team of University of Florida researchers has created tiny hybrid particles that can speedily root out even one isolated E. coli bacterium lurking in ground beef or provide a crucial early warning alarm for bacteria used as agents of bioterrorism and for early disease diagnosis.

First use of technology called ubiquitin-mediated fluorescence complementation to study a cell-signaling mechanism called ubiquitination

Researchers at the University of Michigan Medical School and Howard Hughes Medical Institute have found a way to see proteins in cells that have been tagged by a molecular “sticky note” called ubiquitin.

Novel compound that resembles vitamin E halves the size of tumors and the ability of cancer to spread

By studying cancer in mice, researchers at The University of Texas at Austin have gained preliminary evidence that a novel compound that resembles vitamin E halves the size of tumors and the ability of cancer to spread to other body sites.

New technology to diagnose, treat deadly diseases

By developing a new technology to analyze proteins in single human cells, York University professor Sergey Krylov hopes to create a diagnostic ‘Swiss Army Knife’ that can eventually help to diagnose and treat a variety of currently incurable diseases like cancer, diabetes, Parkinson’s and Alzheimer’s.

Amyloid growth can occur independently of oligomers

Improperly folded proteins are normally destroyed. But in a wide range of diseases, including prion (from proteinaceous and infectious) diseases and neurodegenerative diseases like Parkinson disease and Alzheimer disease, amyloid fibrils, or plaques--misshapen proteins that aggregate into characteristic ropelike configurations--accumulate in tissue.
