Students in Mitchell Pavao-Zuckerman’s UA ecology class took to the streets of Tucson last week to lend their eyes and minds to real science.
You might have looked out your kitchen window last week to see a group of college students standing on the sidewalk clutching notepads and contemplating your front yard. If so, don’t worry – they were likely just counting the shrubbery. (more…)
COLUMBUS, Ohio – A new way to visualize single-cell activity in living zebrafish embryos has allowed scientists to clarify how cells line up in the right place at the right time to receive signals about the next phase of their life.
Scientists developed the imaging tool in single living cells by fusing a protein defining the cells’ cyclical behavior to a yellow fluorescent protein that allows for visualization. Zebrafish embryos are already transparent, but with this closer microscopic look at the earliest stages of life, the researchers have answered two long-standing questions about how cells cooperate to form embryonic segments that later become muscle and vertebrae.

EAST LANSING, Mich. — As Michigan State University’s Recruiting Trends report shows, college students are experiencing a mixed bag of outcomes when it comes to finding a job.
For some MSU students, like MBA candidate Megan Brody, the job search was short and rewarding. For others, like journalism senior Alex Mitchell, the hunt hasn’t led to any full-time positions.
Mitchell, who graduates in December with a degree in journalism, has sent out about 15 resumes to communications employers in Michigan and Ohio hoping to stay close to his hometown of Blissfield in southeastern Michigan. He said he will continue the process until he gets a job he sees fit. (more…)
Teaching future educators how to read and write in a new way
Rachel Karchmer-Klein, an associate professor in the University of Delaware’s School of Education, is teaching future educators to read and write multimodal texts, which includes everything from literature on a Kindle or iPad to information on a website.
“With traditional texts we teach students to read left to right, top to bottom, but electronic text is different because it contains multiple modes,” Karchmer-Klein explained. (more…)
One of the most notable outcomes of the Nov. 6 election was the record number of women voted into Congress, including 20 women who will occupy seats in the U.S. Senate.
Christopher Berry, associate professor at the University of Chicago Harris School of Public Policy, recently discussed the effects of the increase in female U.S. senators. Berry co-authored a 2011 study that found congresswomen consistently outperform their male counterparts on several measures of job performance.
Potentially of great interest to the constituents of the new female senators is our finding that they consistently bring home more federal projects and federal aid than their male counterparts. When you think about disasters like Hurricane Sandy, the ability to bring home federal aid for rebuilding efforts is really important. It is going to be good for their constituents and the states they represent. (more…)
Patterns Also Shed Light on How Environmental Disturbances Affect Aquatic Organisms
The ability of deep-sea corals to harbor a broad array of marine life, including commercially important fish species, make these habitat-forming organisms of immediate interest to conservationists, managers, and scientists. Understanding and protecting corals requires knowledge of the historical processes that have shaped their biodiversity and biogeography.
While little is known about these processes, new research described in the journal Molecular Ecology helps elucidate the historical patterns of deep-sea coral migration and gene flow, coincident with oceanic circulation patterns and events. The investigators propose a scenario that could explain the observed evolutionary and present-day patterns in certain coral species. The findings can help scientists determine how climate change and other global processes have affected ocean habitats in the past and how they might do so in the future. (more…)
China’s endangered wild pandas may need new dinner reservations–and quickly, based on models that indicate climate change may kill off swaths of bamboo that pandas need to survive
In this week’s Nature Climate Change, an international journal, scientists from Michigan State University (MSU) and the Chinese Academy of Sciences provide comprehensive forecasts of how changing climate may affect the most common species of bamboo that carpet the forest floors of prime panda habitat in northwestern China. Even the most optimistic scenarios show that bamboo die-offs would effectively cause prime panda habitat to become inhospitable by the end of the 21st century.
The scientists studied possible scenarios of climate change in the Qinling Mountains in Shaanxi Province. At the northern boundary of China’s panda distributional range, the Qinling Mountains are home to about 275 wild pandas, which account for about 17 percent of the remaining wild population. The Qinling pandas, which have been isolated because of thousands of years of human habitation around the mountain range, vary genetically from other giant pandas. The geographic isolation of these pandas makes them particularly valuable for conservation, but vulnerable to climate change. (more…)
Some arid lands in the American West degraded by military exercises that date back to General George Patton’s Word War II maneuvers in the Mojave Desert should get a boost from an innovative research project led by the University of Colorado Boulder.
Headed up by CU-Boulder Assistant Professor Nichole Barger, the research team is focused on developing methods to restore biological soil crusts — microbial communities primarily concentrated on soil surfaces critical to decreasing erosion and increasing water retention and soil fertility. Such biological soil crusts, known as “biocrusts,” can cover up to 70 percent of the ground in some arid ecosystems and are dominated by cyanobacteria, lichens, mosses, fungi and bacteria, she said.
