Erectile dysfunction has devastating effect on morale
The launch of sildenafil (Viagra) had an adverse effect on the morale of men who found it did not work, according to new research.

Type of buckyball shown to cause brain damage in fish
Researchers have found that a type of buckyball -- a carbon nanoparticle that shows promise for electronic, commercial and pharmaceutical uses -- can cause significant brain damage in fish.

Tadpoles and tumors
The enzymatic activity of FAP is responsible for accelerated tumor growth in mice.

Place of death influences hospital league tables
Geographical variations in facilities for the dying may explain some of the differences between hospitals in league tables of death rates, according to new research from Oxford University.

Self-assembling proteins could help repair human tissue
Johns Hopkins University researchers have created a new class of artificial proteins that can assemble themselves into a gel and encourage the growth of selected cell types.

New technique uses household humidifier to create nanocomposite materials
In what may sound like a project from a high school science fair, scientists are using a household humidifier to create porous spheres a hundred times smaller than a red blood cell.

Carnegie Mellon University creates novel carbon nanoparticles with vast potential
Carnegie Mellon University scientists have developed an attractive way to make discrete carbon nanoparticles for electrical components used in industry and research.

Composite fibers with carbon nanotubes offer improved mechanical & electrical properties
Composites reinforced with carbon nanotubes could ultimately provide the foundation for a new class of strong and lightweight fibers with properties such as electrical and thermal conductivity unavailable in current textile fibers.

Purdue scientists: To stop cancer, keep your Icmt away from your Ras
By investigating a single molecule that influences cell growth, a research group in the Purdue Cancer Center has gained new insight into the development of Ras, an ordinarily beneficial protein that tells a cell to divide.

Fox Chase Cancer Center research reveals how COX-2 causes ovarian cancer
Fox Chase Cancer Center scientists have identified how an enzyme called COX-2 may promote the development of ovarian tumors, adding further insight into the mechanism of COX-2 inhibitors and the prevention of this highly lethal disease.

Researchers: Diet a significant factor in reducing risk of three common cancers
Two case-control studies presented here today at the 95th Annual Meeting of the American Association for Cancer Research compared specific eating habits of healthy individuals to those with prostate and bladder cancers to assess the relationship between dietary factors and incidence of disease.

Nanoparticles for biosensors
Fluorescent nanoparticles that can be attached to biological molecules are being developed for use in microscopic sensor devices.

Nanotech imaging, molecular fingerprints and signatures hold promise for cancer
Scientists described three novel advances aimed at early detection of cancer--a critical key to controlling or curing the disease.

Honey for your health
Honey may have sweet health benefits, according to researchers who conducted what is believed to be the first study of chronic honey consumption in humans.

Scripps Research scientists find deafness gene's function
A group of scientists at The Scripps Research Institute, at the University of California in San Diego, and at the Oregon Hearing Research Center and Vollum Institute at Oregon Health & Science University have discovered a key molecule that is part of the machinery that mediates the sense of hearing.
