China has potential to be leader in global sustainability

China, with its enormous cities and vast countryside, is a potential star in the ongoing global drama of slashing carbon emissions.

In this week’s Nature, a Michigan State University researcher and an international team of sustainability experts propose a script.

China already is a star in unleashing carbon dioxide emissions. In 2011, it accounted for a quarter of the world’s total. The problems – air pollution, squandered energy resources and economic stresses that squelch growth – also come with tremendous opportunity for China to be leader in slashing emissions. Along the way, China’s vast variety of economic and geographic circumstances offers a chance to set examples for its global neighbors. (more…)

China’s chance to reinvent itself environmentally

China’s 34-year-old Environmental Protection Law was created when it made sense for legislators in a developing country to trade environmental well-being for a boost to the gross domestic product.

Today, China wrestles with pollution that is leaving its citizens gasping for clean air, worried about water quality and concerned for the safety of the food grown there. In the current issue of Science, a team of researchers, including a Michigan State University sustainability expert, offers guidelines for revising the EPL to protect both humans and nature. (more…)

Sea lampreys turning up the heat

Male sea lampreys may not be the best-looking creatures swimming in our lakes and streams, but they apparently have something going for them that the ladies may find irresistible.

Research by a team of Michigan State University scientists found that the males have a secondary sex characteristic that creates heat when they get near a female lamprey, something the females find hard to say no to. (more…)

Breaking Dengue Fever

Like malaria, dengue fever is an infectious disease transmitted by mosquitoes. Unlike malaria, there is no vaccine for it. As many as 100 million people contract dengue each year, but MSU researcher Zhiyong Xi is working to change that.

Among the estimated 2.5 billion people at risk for dengue, more than 70 percent live in Asia Pacific countries, which spurred Xi to establish a collaborative research institute at Sun Yat-sen University in Guangzhou, China. (more…)

Going wild could improve winged workforce

Every spring in the United States, bees pollinate crops valued at about $14 billion.

A Michigan State University professor and a team of scientists are using a five-year, $8.6 million grant from the United States Department of Agriculture to keep this winged workforce operating efficiently.

Almonds, strawberries, apples, cherries, blueberries, raspberries, watermelon, cucumbers and more depend on bees to help maximize yields. But with wild honey bee populations decimated by varroa mites and other threats, farmers are dependent on beekeepers to deliver managed colonies of honey bees during peak pollination to ensure their flowers are pollinated.

In the United States, rivers and their floodplains are well-documented and monitored. Ecuador’s largest river, however, remains largely mysterious.

Research led by Michigan State University is helping the South American country unravel the Napo River’s mystique to better balance its economic and environmental treasures. (more…)

Do songbirds hold key to stuttering?

A tiny Australian songbird may hold the answer to discovering the biological source of stuttering, which affects 3 million Americans and is notoriously difficult to treat.

A team of Michigan State University scientists will investigate the brain and behavior of the zebra finch in the first in-depth study of whether stuttering stems from a lack of rhythm. (more…)

In an effort to determine if conditions were ever right on Mars to sustain life, a team of scientists, including a Michigan State University professor, has examined a meteorite that formed on the red planet more than a billion years ago.

And although this team’s work is not specifically solving the mystery, it is laying the groundwork for future researchers to answer this age-old question. (more…)
