Initial, positive results have been reported for a therapeutic vaccine candidate for treating patients with genital herpes. This first-in-class, investigational, protein subunit vaccine, GEN-003, is under development by Genocea Biosciences Inc.

Dr. Anna Wald, University of Washington professor of medicine and laboratory medicine in the School of Medicine and professor of epidemiology in the School of Public Health, is among those leading clinical studies of GEN-003. The trials are also taking place at six other centers in the United States. (more…)

Today’s worst watershed stresses may become the new normal, study finds

Nearly one in 10 U.S. watersheds is “stressed,” with demand for water exceeding natural supply, according to a new analysis of surface water in the United States. What’s more, the lowest water flow seasons of recent years—times of great stress on rivers, streams, and sectors that use their waters—are likely to become typical as climates continue to warm.

“By midcentury, we expect to see less reliable surface water supplies in several regions of the United States,” said the study’s lead author, Kristen Averyt, associate director for science at the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder. “This is likely to create growing challenges for agriculture, electrical suppliers and municipalities, as there may be more demand for water and less to go around.” (more…)

Emotional attachment to robots could affect outcome on battlefield

Too busy to vacuum your living room? Let Roomba the robot do it. Don’t want to risk a soldier’s life to disable an explosive? Let a robot do it.

It’s becoming more common to have robots sub in for humans to do dirty or sometimes dangerous work. But researchers are finding that in some cases, people have started to treat robots like pets, friends, or even as an extension of themselves. That raises the question, if a soldier attaches human or animal-like characteristics to a field robot, can it affect how they use the robot? What if they “care” too much about the robot to send it into a dangerous situation? (more…)

Movement of marine life follows speed and direction of climate change

Scientists expect climate change and warmer oceans to push the fish that people rely on for food and income into new territory. Predictions of where and when species will relocate, however, are based on broad expectations about how animals will move and have often not played out in nature. New research based at Princeton University shows that the trick to more precise forecasts is to follow local temperature changes.

The researchers report in the journal Science the first evidence that sea creatures consistently keep pace with “climate velocity,” or the speed and direction in which changes such as ocean temperature move. They compiled 43 years of data related to the movement of 128 million animals from 360 species living around North America, including commercial staples such as lobster, shrimp and cod. They found that 70 percent of shifts in animals’ depth and 74 percent of changes in latitude correlated with regional-scale fluctuations in ocean temperature. (more…)

Effects of Climate Change on West Nile Virus

A study projects how climate change may affect virus-carrying mosquitoes across the southern U.S. Changes are expected to vary with region, and the southern states should see a trend toward longer seasons of mosquito activity and smaller midsummer mosquito populations

The varied influence of climate change on temperature and precipitation may have an equally wide-ranging effect on the spread of West Nile virus, suggesting that public health efforts to control the virus will need to take a local rather than global perspective, according to a study published this week in the scientific journal Proceedings of the National Academy of Sciences.

Spider Venom Reveals New Secret

Venom of the brown recluse spider causes a reaction in the body that is different from what researchers previously thought, a discovery that could lead to development of new treatments for spider bites.

University of Arizona researchers led a team that has discovered that venom of spiders in the genus Loxosceles, which contains about 100 spider species including the brown recluse, produces a different chemical product in the human body than scientists believed.

The finding has implications for understanding how these spider bites affect humans and for the development of possible treatments for the bites. (more…)

Cool heads likely won’t prevail in a hotter, wetter world

Should climate change trigger the upsurge in heat and rainfall that scientists predict, people may face a threat just as perilous and volatile as extreme weather — each other.

Researchers from Princeton University and the University of California-Berkeley report in the journal Science that even slight spikes in temperature and precipitation have greatly increased the risk of personal violence and social upheaval throughout human history. Projected onto an Earth that is expected to warm by 2 degrees Celsius by 2050, the authors suggest that more human conflict is a likely outcome of climate change. (more…)

Do academic rankings create inequality?

A study led by a Michigan State University scholar questions whether higher education ranking systems are creating competition simply for the sake of competition at a time when universities are struggling financially.

Global rankings that emphasize science and technology research – such as the Academic Rankings of World Universities by Shanghai Jiao Tong University – have become increasingly popular and influential during the past decade, said Brendan Cantwell, lead author and assistant professor of educational administration.
