Social Security vs. Medicare
Despite all the attention paid to Social Security, it's a minor problem compared to Medicare, says leading health economist
| "The problems with Social Security can be solved easily compared to those of Medicare," says Timothy McBride, leading health economist and associate dean for public health at Washington University in St. Louis. "Social Security can be fixed right now, although most people don't want to solve it with tax hikes. If passed today, a one-percentage point tax increase on both employers and employees could solve the Social Security problem for 75 years. If we don't want to raise taxes, another option is to cut benefits by a similar amount and we're done." McBride says that the tax increase needed to fix Medicare would be six or seven percentage points in the long run. "We cannot solve Medicare as easily. Medicare is in a serious crisis relative to Social Security," he says. McBride believes that as soon as the next President is elected "we will hear that we need to solve Medicare and Medicaid."

New technique makes corn ethanol process more efficient
| Researchers at Washington University in St. Louis are proposing to borrow a process used in breweries and wastewater treatment facilities to make corn ethanol more energy efficient. They are exploring the use of oxygen-less vats of microorganisms that naturally feed on organic waste produced from the ethanol fermentation process.

Case is made that high school physics should be taught first
| Physics has a reputation for being the toughest of the high school science courses. But visual models of motion, acceleration, waves, projectiles and other principles help students of all ages build an understanding of physical science concepts. For Jack Wiegers, biology instructor, and Patrick Gibbons, Ph.D., professor of physics, these ideas are a key part of science for students from kindergarten through grade 12. The pair instructs four Science Outreach graduate courses in physical science designed for K-8 teachers. They've also worked with high school teachers in short workshops and in year-long professional learning communities.

Unrest in Russia
Russia views U.S. missile defense in Poland as antagonistic, says expert

Russia's leaders and its population tend to view current developments in Poland through the lens of a basic Russian national narrative that focuses on Russia as a target of invasion by foreign enemies, claims James V. Wertsch, an expert on post-Soviet democracy movements at Washington University in St. Louis. Wertsch was interviewed on this subject and on the Georgia/Russian conflict recently on KMOX radio. The interview is available here.

Man the Hunted
New book further supports controversial theory
|
Despite popular theories to the contrary, early humans evolved not as aggressive hunters, but as prey of many predators. "Humans are no more born to be hunters than to be gardeners," argues Robert W. Sussman, Ph.D., professor of anthropology in Arts & Sciences, in the newly-updated version of the controversial book "Man the Hunted: Primates, Predators and Human Evolution."

Seminar to address ways to lessen earthquake damage
 |
| What should the Midwest do before and after a major earthquake? |
The earthquake that hit the lower Midwest on April 18 of this year was a hearty 5.2 on the Richter scale and got the attention of the St. Louis region. What if a larger quake — occurring either in the New Madrid Fault or Wabash Valley Fault — were to hit the region? How would we respond? To address these concerns, the Department of Mechanical, Aerospace and Structural Engineering at Washington University in St. Louis is presenting a series of seminars and workshops on the topic of reducing the damage that could occur if a strong earthquake strikes the area again.
