2016 Annual Meeting of the Society of Nuclear Medicine and Molecular Imaging Innovative device allows 3-D imaging of the breast with less radiation
Adding a new device to an existing breast molecular imaging system allows the system to get six times better contrast of cancer lesions in the breast, providing the same or better image quality while also potentially reducing the radiation dose to the patient by half. The device may also allow for 3-D molecular breast images at higher resolution than current 2-D scans in a format that may be used alongside 3-D digital mammography.

Journal of Virology Sandia researchers discover mechanism for Rift Valley fever virus infection
Viruses can't live without us -- literally. As obligate parasites, viruses need a host cell to survive. Scientists are exploiting this characteristic by developing therapeutics that close off pathways necessary for viral infection, essentially stopping pathogens in their tracks.
Rift Valley fever virus and other bunyaviruses may soon be added to the list of viruses denied access to a human host. Sandia National Laboratories researchers have discovered a mechanism by which RVFV hijacks the host machinery to cause infection.

Angewandte Chemie Neutrons probe structure of enzyme critical to development of next-generation HIV drugs
A team led by the Department of Energy's Oak Ridge National Laboratory used neutron analysis to better understand a protein implicated in the replication of HIV, the retrovirus that causes AIDS. The enzyme, known as HIV-1 protease, is a key drug target for HIV and AIDS therapies. The multi-institutional team used neutron crystallography to uncover detailed interactions of hydrogen bonds at the enzyme's active site, revealing a pH-induced proton 'hopping' mechanism that guides its activity.

Journal of Orthopaedic Research New research could personalize medicine for arthritis patients
Recently, a team of scientists from Lawrence Livermore National Laboratory, University of California, Davis, University of California, Merced and Regeneron Pharmaceuticals examined the whole-joint gene expression by RNA sequencing at one day, one, six and 12 weeks after injury. The team used a new, non-invasive tibial compression mouse model of PTOA, that mimics ACL rupture in humans from a single high-impact injury.

Nature Structural & Molecular Biology Scientists propose 'pumpjack' mechanism for splitting and copying DNA
New close-up images of the proteins that copy DNA inside the nucleus of a cell have led a team of scientists to propose a brand new mechanism for how this molecular machinery works. The scientists studied proteins from yeast cells, which share many features with the cells of complex organisms such as humans, and could offer new insight into ways that DNA replication can go awry.

Journal of Breast Cancer Research and Treatment New weapon in the fight against breast cancer
Berkeley Lab researchers have developed the first clinically-relevant mouse model of human breast cancer to successfully express functional estrogen receptor positive adenocarcinomas.
This model should be a powerful tool for testing therapies for aggressive ER+ breast cancers and for studying luminal cancers -- the most prevalent and deadliest forms of breast cancer.

Scientific Reports New clues for battling botulism
Scientists have discovered new details about how 'cloaking' proteins protect the toxin that causes botulism, a fatal disease caused most commonly by consuming improperly canned foods. That knowledge and the cloaking proteins themselves might now be turned against the toxin -- the deadliest known to humankind.
