In a paper published Jan. 2 in PLOS Biology, two scientists at the 天美影视传媒 and North Carolina State University use the economic theory of contests to illustrate how the competitive grant-application system has made the pursuit of research funding inefficient and unsustainable 鈥 and that alternative methods, such as a partial lottery to award grants, could relieve pressure on professors and free up time for research.

Two 天美影视传媒 scientists have unveiled a new statistical method for estimating migration flows between countries. They show that rates of migration are higher than previously thought, but also relatively stable, fluctuating between 1.1 and 1.3 percent of global population from 1990 to 2015. In addition, since 1990 approximately 45 percent of migrants have returned to their home countries, a much higher estimate than other methods.

A new collaborative study led by a research team at the Pacific Northwest National Laboratory, University of California, Los Angeles and the 天美影视传媒 could provide engineers new design rules for creating microelectronics, membranes and tissues, and open up better production methods for new materials.

New research from the 天美影视传媒 and Stanford University combines models of ocean conditions and animal metabolism with published lab data and paleoceanographic records to show that the Permian mass extinction in the oceans was caused by global warming that left animals unable to breathe. As temperatures rose and the metabolism of marine animals sped up, the warmer waters could not hold enough oxygen for them to survive.

In a comprehensive study of healthy corals published Nov. 22 in the journal Nature Communications, a team of scientists from the 天美影视传媒 Bothell, Pennsylvania State University and Oregon State University report that coral bacteria are a surprisingly diverse bunch 鈥 and that different sections of the coral body can host unique communities of bacteria.

A new, free tool with temperature and precipitation records across Washington, Oregon, Idaho and western Montana as far back as 1881 lets users play around to discover significant trends. It also includes historical snow records for Washington state.

Here in what is called the Anthropocene era, humans and our urban environments appear to be driving accelerated evolutionary change in plants, animals, fungi, viruses and more 鈥 changes that could affect key ecosystem functions and thus human well-being. These interactions between evolution and ecology are called “eco-evolutionary feedback.” The National Science Foundation has awarded a five-year, $500,000 grant to a multi-institution research network team headed by Marina Alberti, 天美影视传媒 professor of urban design and planning, to advance…

A study by an international team of researchers, including from the 天美影视传媒, determines that carved stone tools, also known as Levallois cores, were used in Asia 80,000 to 170,000 years ago. With the find 鈥 and absent human fossils linking the tools to migrating populations 鈥 researchers believe people in Asia developed the technology independently, evidence of similar sets of skills evolving throughout different parts of the ancient world.

To better understand how state governments across the United States execute their diverse responsibilities, look at their internet footprint, says a new study by researchers at the 天美影视传媒, Harvard University, and Northeastern University.

Researchers from the 天美影视传媒 have shown how Magellanic penguins fare during the winter months when they spend months at sea feeding. They have discovered that oceanographic features are more likely to negatively impact the body conditions of Magellanic penguin females, but not males, when the penguins return to their nesting grounds in spring.

A study led by the 天美影视传媒 is the first large-scale trial of hundreds of PTSD patients, including veterans and survivors of sexual assault, to measure whether patient preference in the course of treatment impacts the effectiveness of both cognitive behavioral therapy and use of selective serotonin reuptake inhibitors, a type of antidepressant often prescribed for PTSD.

Researchers at the 天美影视传媒 have developed a new machine-learning system, called Prescience, which uses input from patient charts and standard operating room sensors to predict the likelihood that a patient will develop hypoxemia 鈥 a condition when blood oxygen levels dip slightly below normal. Prescience also provides real-world explanations behind its predictions.
