Tiny creatures at the bottom of the food chain called diatoms suck up nearly a quarter of the atmosphere's carbon dioxide, yet research by Michigan State University scientists suggests they could become less able to "sequester" that greenhouse gas as the climate warms. The microscopic algae are a major component of plankton living in puddles, lakes and oceans. 

Zoology professor Elena Litchman, with MSU colleague Christopher Klausmeier and Kohei Yoshiyama of the University of Tokyo, explored how nutrient limitation affects the evolution of the size of diatoms in different environments. Their findings underscore potential consequences for aquatic food webs and climate shifts. 

Though the popular conception has been that "money can't buy happiness," studies have shown that wealth can play a role in enhancing happiness.    A study of American woman by a Princeton University psychologist says money doesn't buy happiness - not caring about having no money apparently makes the difference.

Women who concentrated on financial matters were less likely to be happy with their lives, according to Talya Miron-Shatz, a postdoctoral research fellow in the Woodrow Wilson School of Public and International Affairs at Princeton, even though they had plenty of money by conventional standards.

Conversely, those who didn't fixate on finances like retirement savings, tuition for college or simply making ends meet, reported being the happiest of the group.

In a traditional science class, the teacher stands at the front of the class lecturing to a largely passive group of students. Those students then go off and do back-of-the-chapter homework problems from the textbook and take exams that are similar to those exercises.

The climate change skeptic asks - 'Given that the climate changes over millenia due to powerful natural forces, how could humans possibly contribute any significant effect to climate change, given our brief existence in geological time?'

I shall try to answer that question with examples from engineering which show how short-term pulse events can significantly affect long-term cyclic events.

The Influence of Short-Term Events on Long-Term Events.

Synchronized, goal-directed actions are nothing new; that concept is the foundation of civilization.   But it goes much deeper than previously realized, according to research in BMC Neuroscience.    It isn't just voluntary cooperation that happens, sometimes it is at the unconscious brain level.

A new study shows that when musicians play along together it isn't just their instruments that are working together, it is happening at the brain wave level also.  The research details how EEG readouts from pairs of guitarists become more synchronized, a finding with wider potential implications for how our brains interact when we do.

Sixty-one teams from Southern California, Arizona, Brazil and Chile faced off in the Los Angeles regional FIRST Robotics Competition on March 13 and 14. JPL sponsored nine of the schools in this annual engineering and technology contest held at the Long Beach Convention Center. 

The teams from Centinela Valley Union High School District, Lawndale; Atascadero High School, Atascadero; and the NASA-sponsored Bishop Alemany High School, Mission Hills, won the regional competition and will compete in the FIRST championship competition in Atlanta, from April 16-19. Chaminade College Preparatory, in West Hills, won the competition's highest award, the Regional Chairman's Award, and will also go to Atlanta.
