Researchers engineer cells in the eye to be light sensitive that were not before

In an experiment that could offer a new pathway to restoring vision in people with inherited retinal degeneration, researchers have engineered cells in the eye to be light sensitive that were not before.

New discovery could help improve some forms of chemotherapy

The research looked at XPB helicase from an archaea, a single cell organism similar to bacteria. Helicases are enzymes that unwind or separate the strands of the nucleic acid double helix, an action that is critical to transcription and nucleotide excision repair (NER), as well as other cell processes.

Protein loss linked to colon polyp risk from growth hormone

The use of growth hormone therapy has been linked in some people to the development of colon polyps, a possible precursor to colorectal cancer - but medical researchers have debated the extent of a cancer risk.

Discovery of new human retrovirus

Howard Hughes Medical Institute researchers and their colleagues have discovered a new retrovirus in humans that is closely related to a cancer-causing virus found in mice. Their findings describe the first documented cases of human infection with a retrovirus that is native to rodents.

Mass spectrometry could aid biodefense in rapidly detecting dangerous pathogens

Scientists have used mass spectrometry for decades to determine the chemical composition of samples but rarely has it been used to identify viruses, and never in complex environmental samples.

Fish oil may help protect against age-related macular degeneration

A paper published in Trends in Neuroscience by Nicolas G. Bazan, MD, PhD of the Neuroscience Center of Excellence at LSU Health Sciences Center in New Orleans, reports on the role that the omega-3 fatty acids in fish oil play in protecting cells in the retina from degenerative diseases like retinitis pigmentosa and age-related macular degeneration.
