Researchers have found the first proof that a chemical in the brain called glutamate is linked to suicidal behavior, offering new hope for efforts to prevent people from taking their own lives.

Writing in the journal Neuropsychopharmacology, Michigan State University’s Lena Brundin and an international team of co-investigators present the first evidence that glutamate is more active in the brains of people who attempt suicide. Glutamate is an amino acid that sends signals between nerve cells and has long been a suspect in the search for chemical causes of depression. (more…)

Protein Strongest Just Before Death

Researchers at Michigan State University have discovered a protein that does its best work with one foot in the grave.

The study, which appears in the current issue of the Journal of Biological Chemistry, focuses on the nontraditional lifestyle of Retinoblastoma tumor suppressor proteins, which could lead to new ways to treat cancer.

“Retinoblastoma proteins are unique in that they use controlled destruction to do their jobs in a timely but restrained fashion,” said Liang Zhang, a lead author and MSU cell and molecular biology graduate student. “This is an unusual way for proteins to act.” (more…)

Mastering Scientific Mumbo Jumbo

About the video: Discusses the interaction between abiotic and biotic factors. The style of the animation is influenced by The Common Craft Show.

Warning: This class will teach students to translate scientific mumbo jumbo into understandable phrases.

Michigan State University’s first, free Massive Open Online Course, or MOOC, also promises to then teach students “to speak mumbo jumbo and amaze your friends.” (more…)

Adolescents Under Pressure to Speak ‘Properly’

As adolescents transition to adulthood, the pressure to meet adult expectations – such as speaking properly – may be greater than expected, according to a new study by a Michigan State University researcher.

Suzanne Evans Wagner, assistant professor of linguistics in the College of Arts and Letters, has proven for the first time that language changes with age in addition to community pressures. And, surprisingly, college and post-high school ambitions play a huge role. (more…)

Multiple Media Use Tied to Depression, Anxiety

Using multiple forms of media at the same time – such as playing a computer game while watching TV – is linked to symptoms of anxiety and depression, scientists have found for the first time.

Michigan State University’s Mark Becker, lead investigator on the study, said he was surprised to find such a clear association between media multitasking and mental health problems. What’s not yet clear is the cause. (more…)

Energy Savings – Easy as Dirt, Heat, Pressure

By using common materials found pretty much anywhere there is dirt, a team of Michigan State University researchers have developed a new thermoelectric material.

This is important, they said, because the vast majority of heat that is generated from, for example, a car engine, is lost through the tail pipe. It’s the thermoelectric material’s job to take that heat and turn it into something useful, like electricity. (more…)

EAST LANSING, Mich. — Where there’s water there’s life – even in brine beneath 60 feet of Antarctic ice, in permanent darkness and subzero temperatures.

While Lake Vida, located in the northernmost of the McMurdo Dry Valleys of East Antarctica, will never be a vacation destination, it is home to some newly discovered hearty microbes. In the current issue of the Proceedings of the National Academy of Science, Nathaniel Ostrom, Michigan State University zoologist, has co-authored “Microbial Life at -13ºC in the Brine of an Ice-Sealed Antarctic Lake.” (more…)

Support for Gay Marriage Grows in Michigan

EAST LANSING, Mich. — Support for gay marriage is growing in Michigan, mirroring changing attitudes in many parts of the United States, according to Michigan State University’s State of the State Survey.

A recent survey found that 56 percent of the state’s residents support gay marriage while 39 percent oppose it. Two years ago, 48 percent supported gay marriage and 51 percent were opposed. (more…)
