Neutrons poised to play big role in future scientific advance
Subatomic particles called neutrons are poised to play a big role in fighting HIV, slowing global warming, and improving manufacturing processes. The reason: They are the focus of a process called neutron scattering that provides unprecedented ways to study the chemistry of a wide range of important materials, including coal and biological cells, according to an article in Chemical & Engineering News, ACS' weekly news magazine.

A hot road to new drugs
The quest for new drugs is generally a lengthy and costly undertaking. Researchers of Ludwig-Maximilians-Universitaet in Munich have now come up with a simpler and more efficient way of going about it. Not only pharmaceutical research but also medical diagnostics and the environment stand to benefit from the new work.

Bone marrow cell transplants to benefit those with heart disease
Separate bone marrow cell transplantation studies may lead to new treatments for the treatment of heart diseases. One study by a team of Brazilian researchers, found that cell transplantation of bone marrow mononuclear cells (BMMCs) and ReACT formula injected directly into the heart benefited patients suffering from refractory angina. A second study in the Peoples' Republic of China found that apelin, a newly described inotropic peptide, improves heart function following transplantation of BMMCs.

The sound of melanoma can help doctors find cancer
University of Missouri researchers in the Christopher S. Bond Life Sciences Center are studying how photoacoustics, or a laser-induced ultrasound, could help scientists locate the general area of the lymph node where melanoma cells could be residing. This new technology could help doctors identify the stage of melanoma with more accuracy.

Melanoma transcriptome reveals novel genomic alterations not seen before
Melanoma, the most deadly form of skin cancer, afflicts more than 50,000 people in the United States annually and the incidence rate continues to rise. In a study published online in Genome Research, scientists have delved deeper than ever before into the RNA world of the melanoma tumor and identified genomic alterations that could play a role in the disease.Starr Cancer Consortium, Melanoma Research Alliance, Novartis Institutes of Biomedical Research, Adelson Medical Research Foundation

Pandemic Hybrid Of Bird And Human Seasonal Flu Possible Say Scientists
An international team of scientists has created a highly pathogenic laboratory hybrid of the H5N1 bird flu and human seasonal flu viruses by swapping just one gene, and propose that a similar genetic interaction could happen in nature between the current pandemic H1N1 swine flu and H5N1 avian flu strains, highlighting the importance of continued surveillance. A report of the study by senior author is Dr Yoshihiro Kawaoka, professor of pathobiological sciences in the School of Veterinary Medicine at the University of Wisconsin-Madison in the US, and colleagues, appeared online before print on 22 February in the Proceedings of the National Academy of Sciences, PNAS.

Approximately 57 million Americans are on the brink of diabetes . Yet research tells us that there is much we can do to keep it from progressing to full-blown diabetes. Lab tests can help us get a grip on the disease, says the American Clinical Laboratory Association President Alan Mertz. "Ask your doctor about a quick and easy lab test called hemoglobin A1C (A1C). The test can tell you if you actually have diabetes or are close to developing it a silent and serious condition called pre-diabetes," says Mertz.

Predicting The Progression Of Alzheimer's
An assessment has been developed which reliably predicts future performance in cognition and activities of daily living for patients withAlzheimer's disease . Researchers writing in BioMed Central's open access journal Alzheimer's Research & Therapy followed 597 patients over 15 years to identify factors associated with slow, intermediate and rapid progression. Professor Rachelle Doody worked with a team of researchers from Baylor College of Medicine, Texas, US, to carry out the study. She said, "Patients and families frequently ask clinicians to predict expected rates of cognitive and functional decline, and clinicians currently have little basis for making such decisions. We've found that a simple, calculated progression rate at the initial visit gives reliable information regarding performance over time. The slowest progression group also survives longer."

Ultra-Fast Lasers Open Doors To New Technologies Unheard Of Just Years Ago
For nearly half a century, scientists have been trying to figure out how to build a cost-effective and reasonably sized X-ray laser that could, among other things, provide super high-resolution imaging. And for the past two decades, University of Colorado at Boulder physics professors Margaret Murnane and Henry Kapteyn have been inching closer to that goal. Recent breakthroughs by their team at JILA, a joint institute of CU-Boulder and the National Institute of Standards and Technology, have paved the way on how to build a tabletop X-ray laser that could be used for super high-resolution imaging, while also giving scientists a new way to peer into a single cell and gain a better understanding of the nanoworld.
