A ribbon of ice more than 600 kilometers long that drains about 12 percent of the gigantic Greenland Ice Sheet has been smaller than it is today about half of the time over the past 45,000 years, a new study suggests.

New research reveals the growth of carbon production from Chinese exports has slowed or reversed, reflecting a “new phase of globalisation” between developing countries that could undermine international efforts to reduce emissions.

Transplanting fungi to restore native plant populations in the Midwest and Northwest is the focus of efforts by a team of WSU Tri-Cities researchers.

A team of biophysicists from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) presents a mathematically concise method for comparing different pricing models in their latest publication in Nature Communications. This enables researchers to predict more accurately how parameters such as the volatility of stock prices change over time.*

With more space exploration and possible colonization on the horizon, a group of international researchers, including the University of Lethbridge’s Dr. Olga Kovalchuk, combined forces to produce a roadmap to enhancing human radioresistance, or the level of radiation an organism is able to withstand. The group recently published a paper exploring the subject in the peer-reviewed journal Oncotarget.

Billions of years ago, when Earth’s atmosphere reeked of unbreathable gases, microbes evolved in the absence of oxygen. As Earth matured and the nitrogen-oxygen atmosphere formed, these anaerobic, or oxygen-averse, bacteria retreated into the mud of the ocean floor and other environments where they would be safe from oxygen-rich air.

Operation IceBridge, NASA’s longest-running airborne mission to monitor polar ice change, concluded this year’s springtime survey of Arctic sea and land ice on May 2. The flights, which began on March 22, covered the western basin of the Arctic Ocean and Greenland’s fastest-changing glaciers.

• Cancer patients are at high risk of developing blood clots

• Deep vein thrombosis (DVT) and pulmonary embolism (PE) collectively known as venous thromboembolism (VTE), can cause death and disability

Western China and central Asia are positioned centrally along the Millennium Silk Road—a core region bridging the east and west. Understanding the potential changes in climate over this core region is important to the successful implementation of “Belt and Road Initiative” (a US$1 trillion regional investment in infrastructure). In a recently published study in Atmospheric and Oceanic Science Letters, scientists from the Institute of Atmospheric Physics, Chinese Academy of Sciences, projected both mean and extreme climate changes using the ensemble mean of CMIP5 models. The comparison of mean and extreme climate changes under 1.5°C and 2°C global warming scenarios highlights the impacts that can be avoided by achieving global warming of half a degree lower.

Identifying the sources of aerosol ammonium is essential because ammonium can impact the Earth’s radiative balance, as well as human health and biological diversity. The sources of ambient ammonia concentrations can be quantified based on the stable isotopic composition of ammonia for various endmembers. However, isotopic source apportionment of aerosol ammonium is challenging in the urban atmosphere, where there is excess ammonia and nitrogen isotopic fractionation commonly occurs.
