GAINESVILLE, Fla. --- Call it Nitelite: The newest app for cell phones might be night vision.

A University of Florida engineering researcher has crafted a nickel-sized imaging device that uses organic light-emitting diode technology similar to that found in cell phone or laptop screens for night vision. But unlike night vision goggles, which are heavy and expensive, the device is paper-thin, light and inexpensive, making it a possible add-on to cell phone cameras, even eyeglasses, once it is enlarged.

(PHILADELPHIA) – Researchers at Thomas Jefferson University have found that colonoscopy preparation drugs administered the same day as the procedure are equally effective to those given the night before and the morning of the procedure, but result in less complaints of side effects such as abdominal pain, sleep loss and workday interference.

New Orleans, LA – Researchers at LSU Health Sciences Center New Orleans and Children's Hospital of New Orleans have found that there is a major difference in the hemoglobin A1c (HbA1c) response to blood glucose between African-American and Caucasian children with diabetes. HbA1c is the main test used to monitor diabetes and guide treatment decisions. African-American children test significantly higher than Caucasians who have similar average blood glucose levels. The research may explain why African Americans are at increased risk of diabetes complications.

May 3, 2010 -- A study by researchers at Columbia University's Mailman School of Public Health suggests that traumatic experiences "biologically embed" themselves in select genes, altering their functions and leading to the development of post-traumatic stress disorder (PTSD).

BLOOMINGTON, Ind. -- A field study of the relationship between testosterone and natural selection in an American songbird, the dark-eyed junco, has defied some expectations and confirmed others.

AUGUSTA, Ga. - An eye under pressure appears to express a unique set of proteins that physicians hope will one day help them better diagnose and treat glaucoma.

Researchers at the Swedish medical university Karolinska Institutet have discovered a new control mechanism in our immune system. The discovery is of potential significance to the treatment of serious diseases such as MS (multiple sclerosis), rheumatoid arthritis, and SLE (Systemic lupus erythematosus).

Australian researchers have published the results of a study, for the first time showing a positive effect of growth hormone on athletic performance.

It showed a .4 second improvement in a 10-second sprint, enough to turn a last-place Olympic athlete in a sprint event – running or swimming - into a Gold medal winner.

The study justifies growth hormone being a banned substance, even though evidence of its performance enhancing effect has been very poor until now.

DALLAS – May 4, 2010 – A national study involving a UT Southwestern Medical Center neonatologist and pediatric infectious diseases specialist suggests that a screening test routinely performed in newborns is not very good at identifying cytomegalovirus (CMV) infection, a leading cause of hearing loss in children.

The findings, published in the April 14 issue of the Journal of the American Medical Association, suggest that testing blood drawn from a newborn's heel has limited value in detecting CMV infection.

UCLA researchers report in the April 30 edition of the journal Cell that they have imaged a virus structure at a resolution high enough to effectively "see" atoms, the first published instance of imaging biological complexes at such a resolution.

The research team, led by Hong Zhou, UCLA professor of microbiology, immunology and molecular genetics, used cryo-electron microscopy to image the structure at 3.3 angstroms. An angstrom is the smallest recognized division of a chemical element and is about the distance between the two hydrogen atoms in a water molecule.

In the depths of a former copper mine in Northern California dwell what may be the smallest, most stripped-down forms of life ever discovered.
