Death Valley study helps determine evolution of western US landscapes

The faulted alluvial fans near Badwater in Death Valley are amongst the most visited and classic landforms in the U.S. New mapping and dating of these landforms, presented in this open-access study by Kurt Frankel and colleagues, help to determine the timing of past earthquakes and how tectonic deformation is distributed across the western U.S. This in turn provides important data for seismic hazard mitigation and for understanding how the great landscapes of the western U.S

International research partnership yields discovery of a new fossil species

An international research partnership is revealing the first mosasaur fossil of its kind to be discovered in Japan. Not only does the 72-million-year-old marine reptile fossil fill a biogeographical gap between the Middle East and the eastern Pacific, but also it holds new revelations because of its superior preservation. This unique swimming lizard, now believed to have hunted on glowing fish and squids at night, is detailed in an article led by Takuya Konishi, a University of Cincinnati assistant professor of biological sciences.

Increased CO2 in the atmosphere has altered photosynthesis of plants over the 20th century

Researchers at Umeå University and the Swedish University of Agricultural Sciences have discovered that increasing levels of CO2 in the atmosphere have shifted photosynthetic metabolism in plants over the 20th century. This is the first study worldwide that deduces biochemical regulation of plant metabolism from historical specimens. The findings are now published in the leading journal PNAS and will have an impact on new models of future CO2 concentration in the atmosphere.

Three studies point to effectiveness of new therapies for multiple myeloma

In a trio of studies to be presented at the 57th American Society of Hematology (ASH) Annual Meeting and Exposition in Orlando, investigators at Dana-Farber Cancer Institute will present the results of clinical trials showing that new drug combinations can significantly extend the time in which multiple myeloma is kept in check in patients with relapsed or treatment-resistant forms of the disease. read more

Study identifies characteristics that may increase a breast cancer survivor’s risk of developing leukemia following treatment

A new analysis indicates that certain characteristics may increase a breast cancer survivor’s risk of developing leukemia after undergoing chemotherapy and/or radiation. Published early online in CANCER , a peer-reviewed journal of the American Cancer Society, the findings are a first step toward finding ways to prevent this serious and potentially life-threatening treatment-related complication

Dinosaur relatives and first dinosaurs more closely connected than previously thought

A new study by a team of scientists from Argentina, Brazil, California and the Natural History Museum of Utah at the University of Utah has determined that the time elapsed between the emergence of early dinosaur relatives and the origin of the first dinosaurs is much shorter than previously believed. The discovery not only places a new timeline on the connection between early dinosaur relatives and the first dinosaurs in this particular geologic formation, but also in other formations across the world.

Satellite observations show global plant growth is not keeping up with CO2 emissions

Because plants need carbon dioxide to grow, scientists have expected rising atmospheric CO2 to substantially enhance plant growth, offsetting a portion of human CO2 emissions and, in turn, slowing climate change. However, new research from the Institute on the Environment published today in Nature Climate Change adds to a growing body of research challenging this expectation
