Ancient Lamprey DNA Decoded

When it comes to evolution, humans can learn a thing or two from primeval sea lampreys.

In the current issue of Nature Genetics, a team of scientists has presented an assembly of the sea lamprey genome – the first time the entire sequence has been decoded. The data is compelling as the sea lamprey is one of the few ancient, jawless species that has survived through the modern era.

The paper not only sheds light on how the venerable invasive species adapted and thrived, but it also provides many insights into the evolution of all vertebrates, species with backbones and spinal cords, which includes humans, said Weiming Li, Michigan State University fisheries and wildlife professor, who organized and coordinated the team.

A Whole New Game in Cancer Rehab

Using a video game system to get exercise at home can help patients overcome one of cancer’s most common and cumbersome symptoms: severe, persistent fatigue.

Michigan State University’s Amy Hoffman and colleagues showed in an earlier study that the Nintendo Wii system was a safe and effective source of light-intensity exercise for patients with non-small cell lung cancer in the first six weeks after surgery. (more…)

Wanted: A Life Outside the Workplace

A memo to employers: Just because your workers live alone doesn’t mean they don’t have lives beyond the office.

New research at Michigan State University suggests the growing number of workers who are single and without children have trouble finding the time or energy to participate in non-work interests, just like those with spouses and kids.

Workers struggling with work-life balance reported less satisfaction with their lives and jobs and more signs of anxiety and depression. (more…)

Today’s consumers switch between media forms so often – from TV to laptops to smart phones – that capturing their attention with advertising has gone, as one CEO explained, from shooting fish in a barrel to shooting minnows. (more…)

In what could be an early step toward new treatments for people with osteoporosis, scientists at Michigan State University report that a natural probiotic supplement can help male mice produce healthier bones.

Interestingly, the same can’t be said for female mice, the researchers report in the Journal of Cellular Physiology.

“We know that inflammation in the gut can cause bone loss, though it’s unclear exactly why,” said lead author Laura McCabe, a professor in MSU’s departments of Physiology and Radiology. “The neat thing we found is that a probiotic can enhance bone density.” (more…)

Unchecked Antibiotic Use in Animals May Affect Global Human Health

The increasing production and use of antibiotics, about half of which is used in animal production, is mirrored by the growing number of antibiotic resistance genes, or ARGs, effectively reducing antibiotics’ ability to fend off diseases – in animals and humans.

A study in the current issue of the Proceedings of the National Academy of Sciences shows that China – the world’s largest producer and consumer of antibiotics – and many other countries don’t monitor the powerful medicine’s usage or impact on the environment. (more…)

A recently published study by a team of Michigan State University researchers found that one effective way of fighting cyberbullying is by using the medium where it tends to flourish. The key, said the researchers: Make your anti-cyberbullying messages positive in nature. (more…)

Few Pregnant Women Treated for Sexually Transmitted Infections

Many pregnant women with sexually transmitted infections aren’t getting the treatment they need when they visit emergency rooms, according to a new Michigan State University study that highlights a wholly preventable risk to unborn children and raises questions about current medical guidelines.

About half of the 735 women with gonorrhea or chlamydia who visited the ERs at three hospitals in Grand Rapids, Mich. from 2008 through 2010 did not get treatment there, despite the availability of effective and relatively inexpensive antibiotics. Of the 179 who were pregnant, only 20 percent received treatment in the ER. (more…)
