How the Slime Mold Gets Organized

*Cells at the tip of the slime mold’s fruiting body organize into an epithelial layer and secrete proteins as do some animals cells*

The so-called cellular slime mold, a unicellular organism that may transition into a multicellular organism under stress, has just been found to have a tissue structure that was previously thought to exist only in more sophisticated animals. What’s more, two proteins that are needed by the slime mold to form this structure are similar to those that perform the same function in more sophistical animals.

Shortly after an animal embryo forms, it develops a single layer of cells that, shaped like a hollow ball, is empty at its center. Acting as a kind of “man behind the curtain” that directs these cells to organize into this hollow formation are several proteins that help each cell touch its neighbors but keep its top surface exposed to the formation’s empty interior.

Regrowing Hair: UCLA-VA Researchers May Have Accidentally Discovered a Solution

It has been long known that stress plays a part not just in the graying of hair but in hair loss as well. Over the years, numerous hair-restoration remedies have emerged, ranging from hucksters’ “miracle solvents” to legitimate medications such as minoxidil. But even the best of these have shown limited effectiveness.

Now, a team led by researchers from UCLA and the Veterans Administration that was investigating how stress affects gastrointestinal function may have found a chemical compound that induces hair growth by blocking a stress-related hormone associated with hair loss — entirely by accident. (more…)

EAST LANSING, Mich. — In the first combat-zone study of its kind, a research team led by Michigan State University found that soldiers with a positive outlook in the most traumatic situations were less likely to suffer health problems such as anxiety and depression.

The study, which surveyed Army troops fighting in Iraq, could have implications for police officers, firefighters and others who regularly deal with traumatic events such as death. Training these first-responders to think in less catastrophic terms could help them better cope with distressing events and function more effectively in the long term, said MSU’s John Schaubroeck, lead researcher on the project.

A recent study found that not all heart attacks could be traced by electrocardiogram (ECG). These ‘not all heart attacks’ include a little known category (in mass public) – ‘silent’ heart attacks. (more…)
