Study validates means to measure possible leukemia marker

Ohio State University cancer researchers show that a technology called liquid chromatography-mass spectroscopy can reliably and reproducibly measure variations in the composition of histone proteins in chronic lymphocytic leukemia (CLL) cells compared with their healthy counterparts, immune cells called B lymphocytes. These variations are a promising molecular biomarker that might improve the diagnosis and gauge response to therapy in CLL patients. The findings mean that the technology can measure histone variations in clinical research.

Researchers at Sandia National Laboratories have created the first carbon nanotube device that can detect the entire visible spectrum of light, a feat that could soon allow scientists to probe single molecule transformations, study how those molecules respond to light, observe how the molecules change shapes, and understand other fundamental interactions between molecules and nanotubes.

Finding a stereotype that is true: Mexicans more sociable than Americans

Stereotypes often paint a partial or false picture of an individual or group.But now researchers have found evidence that supports a stereotype held by many in the United States — that Mexicans are more outgoing, talkative, sociable and extroverted. The finding also contradicts the way many Mexicans view themselves as being less extroverted than Americans.

NASA study says climate adds fuel to Asian wildfire emissions

In the last decade, Asian farmers have cleared tens of thousands of square miles of forests to accommodate the world’s growing demand for palm oil, an increasingly popular food ingredient. Ancient peatlands have been drained and lush tropical forests have been cut down. As a result, the landscape of equatorial Asia now lies vulnerable to fires, which are growing more frequent and having a serious impact on the air as well as the land.

Mysterious disappearance of explorer Everett Ruess solved after 75 years

The mysterious disappearance of Everett Ruess, a 20-year-old artist, writer and footloose explorer who wandered the Southwest in the early 1930s on a burro and who has become a folk hero to many, has been solved with the help of University of Colorado at Boulder researchers and the National Geographic Society.

Type of connection procedure after pancreatic surgery influenced rate of panc…

After surgery to remove the head of the pancreas, invagination of the pancreas into the small intestine resulted in a lower rate of pancreatic fistula, according to researchers at the Jefferson Pancreas, Biliary and Related Cancer Center. The research was published in the Journal of the American College of Surgeons. It was performed as a randomized trial — the gold standard for studies
