Sandia Creates Better ‘Fingerprints’ to Detect Elusive, Valuable Chemical Compounds

Balint-Sztaray-David-Osborn.jpg

Imagine being able to see the entire Statue of Liberty and a small ant on its nose simultaneously. The drastic difference in size between the two objects would seem to render this task impossible. On a molecular level, this is exactly what a team led by Sandia National Laboratories chemists David Osborn and Carl Hayden accomplished with a special, custom-made instrument that has enhanced the power of a method called photoelectron photoion coincidence, or PEPICO, spectroscopy. This enhanced method could yield new insights into chemical reactions in the troposphere (the lowest layer of the Earth’s atmosphere) and in low-temperature combustion.

Alcohol Use Among Homeless Youth Due to Victimization Varies by Gender and Type of Abuse

Unaccompanied homeless youth, especially females, have high rates of sexual and physical victimization – both before and after leaving home. These findings and others will be shared at the 40th annual scientific meeting of the Research Society on Alcoholism (RSA) in Denver June 24-28.

Barrier Proteins in Tumors are Possible Key to Immunotherapy Success

GeneTherapy_Cancer_iStock-664349508.jpg

By comparing variations in protein expression in tumor samples from a single melanoma patient, researchers from the Johns Hopkins Bloomberg~Kimmel Institute and the Memorial Sloan-Kettering Cancer Center say their findings have the potential to reveal some of the mechanisms underlying response or resistance to immunotherapy drugs. The “proof of concept” findings, published online Feb. 13, 2017, in Clinical Cancer Research, point to distinct variations not in the genetic code of each tumor sample, but in the expression levels of certain proteins encoded by normal genes.

Does Religion Protect Against Suicide?

Religious participation is linked to lower suicide rates in many parts of the world, including the United States and Russia, but does not protect against the risk of suicide in sections of Europe and Asia, finds new research by a Michigan State University scholar.

Injectable Plant-based Nanoparticles Delay Tumor Progression

The researchers discovered injecting potato virus particles into melanoma tumor sites activates an anti-tumor immune system response. And simultaneously injecting the nanoscale plant virus particles and a chemotherapy drug—doxorubicin—into tumor sites further helps halt tumor progression in mice.
