Unveiled: Earth's viral diversity
Plumbing the Earth's microbial diversity requires learning more about the poorly-studied relationships between microbes and the viruses that infect them, impacting their abilities to regulate global cycles. DOE JGI researchers utilized the largest collection of assembled metagenomic datasets to uncover over 125,000 partial and complete viral genomes. This single effort increases the number of known viral genes by a factor of 16, and provides researchers with a unique resource of viral sequence information.

Researchers at Sandia, Northeastern develop method to study critical HIV protein
Mike Kent, a researcher in Sandia National Laboratories' Biological and Engineering Sciences Center, is studying a protein called Nef involved in HIV progression to AIDS with the ultimate goal of blocking it. He and his collaborators have developed a new hybrid method to study this HIV protein that compromises the immune system. The method also could work on many other proteins that damage cellular processes and cause diseases.

Researchers find molecular switch that triggers bacterial pathogenicity
A new study led by scientists at Berkeley Lab has revealed that the supercoiling of bacterial chromosomes around histone-like proteins can trigger the expression of genes that make the microbe invasive. The discovery could provide a new target for the development of drugs to prevent or treat bacterial infection.

All e-cigarettes emit harmful chemicals, but some emit more than others
While previous studies have found that electronic cigarettes emit toxic compounds, a new study from Lawrence Berkeley National Laboratory has pinpointed the source of these emissions and shown how factors such as the temperature, type, and age of the device play a role in emission levels, information that could be valuable to both manufacturers and regulators seeking to minimize the health impacts of these increasingly popular devices.

Scientists create new thin material that mimics cell membranes
Materials scientists have created a new material that performs like a cell membrane found in nature. Such a material has long been sought for applications as varied as water purification and drug delivery. The material can assemble itself into a sheet thinner but stabler than a soap bubble, the researchers report July 12 in Nature Communications.

Scientists determine structure of enzyme linked with key cell-signaling protein
Scientists have captured atomic level snapshots showing how one key enzyme modifies a protein involved in turning genes on or off inside cells. Understanding this process helps explain how complex organisms can arise from a finite number of genes. The research also identifies links between defects in this particular enzyme and certain cancers, potentially pointing to new drug targets.

Ovarian cancer study provides painstaking look at inner workings of tumors
Scientists have examined the collections of proteins in the tumors of 169 ovarian cancer patients to identify critical proteins present in their tumors. The researchers say their achievement illustrates the power of combining genomic and proteomic data -- an approach known as proteogenomics -- to yield a more complete picture of the biology of a cancer that is the fifth leading cause of cancer deaths among women in the United States.

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.

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.

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.

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.

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.
