Science Translational MedicineIntestinal bacteria may fuel inflammation and worsen HIV disease A new study of HIV infection by UC San Francisco researchers points to changes in intestinal bacteria as a possible explanation for why successfully treated HIV patients nonetheless prematurely experience life-shortening chronic diseases.

Palaeogeoraphy, Palaeocilmatology, PalaeoecologyJournal highlights Arctic sea ice study by UM professor New research by University of Montana bioclimatology Assistant Professor Ashley Ballantyne models the influence of Arctic sea ice on Arctic temperatures during the Pliocene era. His research was published in the Research Highlight section of the July issue of Nature Geoscience. The full paper will be published in Palaeogeography, Palaeoclimatology, Palaeoecology: An International Journal for the Geosciences.

AstrobiologyCU study shows how early Earth kept warm enough to support life Solving the "faint young sun paradox" -- explaining how early Earth was warm and habitable for life beginning more than three billion years ago even though the sun was 20 percent dimmer than today -- may not be as difficult as believed, says a new University of Colorado Boulder study.

Proceedings of the National Academy of SciencesScientists image vast subglacial water system under West Antarctica's Thwaites Glacier In a development that will help predict sea level rise, scientists have used an innovation in radar analysis to accurately image the vast subglacial water system under West Antarctica's Thwaites Glacier, detecting a swamp-like canal system several times as large as Florida's Everglades. The new observations suggest dynamics of the subglacial water system may be as important as ocean influences in predicting the fate of Thwaites, which holds substantial potential for triggering sea-level rise.

Proceedings of the Royal Society BBiceps bulge, calves curve, 50-year-old assumptions muscled aside The basics of how a muscle generates power remain the same: Filaments of myosin tugging on filaments of actin shorten, or contract, the muscle -- but the power doesn't just come from what's happening straight up and down the length of the muscle, as has been assumed for 50 years.

Proceedings of the National Academy of SciencesGlimpse into the future of acidic oceans shows ecosystems transformed In the waters surrounding Castello Aragonese, a 14th century castle off the coast of Italy, volcanic vents naturally release bubbles of carbon dioxide gas, creating different levels of acidity among the marine-animal and plant communities there. These gradients of acidity gave UC Davis scientists a glimpse of what a future marked by increasingly acidic ocean waters could look like, and how the creatures and plants living in those environments may react to it.

ACS NanoEavesdropping on lithium ions It's a jungle down there at batteries' atomic level, with ions whacking into electrodes, eventually causing the battery to fail. Now, a Michigan Technological University scientist has developed a device that lets researchers spy on the actions of lithium ions inside a nanobattery -- and use that data to develop better, longer-lasting batteries to power everything from electric cars to cell phones.

Global Biogeochemical CyclesHarvard researchers warn of legacy mercury in the environment Environmental researchers at Harvard University have published evidence that significant reductions in mercury emissions will be necessary just to stabilize current levels of the toxic element in the environment. So much mercury persists in surface reservoirs (soil, air, and water) from past pollution, going back thousands of years, that it will continue to persist in the ocean and accumulate in fish for decades to centuries, they report.

PLOS ONEIn subglacial lake, surprising life goes on Lake Vostok, buried under a glacier in Antarctica, is so dark, deep and cold that scientists had considered it a possible model for other planets, a place where nothing could live. However, work by Dr. Scott Rogers, a Bowling Green State University professor of biological sciences, and his colleagues has revealed a surprising variety of life forms living and reproducing in this most extreme of environments.

Cell Stem CellStudy challenges long-held assumption of gene expression in embryonic stem cells Whitehead Institute researchers have determined that the transcription factor Nanog, which plays a critical role in maintaining the self-renewal of embryonic stem cells, is expressed in a manner similar to other pluripotency markers. This finding contradicts the field's presumptions about this important gene and its role in the differentiation of embryonic stem cells.

CellScientists identify gene that controls aggressiveness in breast cancer cells Whitehead Institute researchers have determined that in basal breast cancer cells a transcription factor known as ZEB1 is held in a poised state, ready to increase the cells' aggressiveness and enable them to transform into cancer stem cells capable of seeding new tumors throughout the body. Intriguingly, luminal breast cancer cells, which are associated with a much better clinical prognosis, carry this gene in a state in which it seems to be permanently shut down.

PLOS ONEStudy of mitochondrial DNA ties ancient remains to living descendants Researchers report that they have found a direct genetic link between the remains of Native Americans who lived thousands of years ago and their living descendants. The team used mitochondrial DNA, which children inherit only from their mothers, to track three maternal lineages from ancient times to the present. The findings are reported in the journal PLOS ONE.
