Complex brains evolved much earlier than previously thought, as evidenced by a 520-million-year-old fossilized arthropod with remarkably well-preserved brain structures.

The remarkably well-preserved fossil of an extinct arthropod shows that anatomically complex brains evolved earlier than previously thought and have changed little over the course of evolution. According to University of Arizona neurobiologist Nicholas Strausfeld, who co-authored the study describing the specimen, the fossil is the earliest known to show a brain.

The discovery will be published in the Oct. 11 issue of the journal Nature. (more…)

Amazonian Tribal Warfare Sheds Light on Modern Violence, Says MU Anthropologist

Developing a shared sense of global community could help reduce major episodes of violence

In the tribal societies of the Amazon forest, violent conflict accounted for 30 percent of all deaths before contact with Europeans, according to a recent study by University of Missouri anthropologist Robert Walker. Understanding the reasons behind those altercations in the Amazon sheds light on the instinctual motivations that continue to drive human groups to violence, as well as the ways culture influences the intensity and frequency of violence.

“The same reasons – revenge, honor, territory and jealousy over women – that fueled deadly conflicts in the Amazon continue to drive violence in today’s world,” said Walker, lead author and assistant professor of anthropology in MU’s College of Arts and Science. “Humans’ evolutionary history of violent conflict among rival groups goes back to our primate ancestors. It takes a great deal of social training and institutional control to resist our instincts and solve disputes with words instead of weapons. Fortunately, people have developed ways to channel those instincts away from actual deadly conflict. For example, sports and video games often involve the same impulses to defeat a rival group.” (more…)

Scientists Uncover Vast Differences in Earth’s Polar Ocean Microbial Communities

ANN ARBOR— An international team of scientists, including a University of Michigan graduate student, has demonstrated that a clear difference exists between the marine microbial communities in the Southern and Arctic oceans, contributing to a better understanding of the biodiversity of marine life at the poles.

The most comprehensive comparison of microbial diversity at both of Earth’s polar oceans showed that about 75 percent of the organisms at each pole are different. This insight sheds light on newly recognized biodiversity patterns and reinforces the importance of studying Earth’s polar regions in the face of a changing climate. And it highlights the need for further research on the impacts of sea ice, seasonal shifts and freshwater input in both regions. (more…)

Artistry of ‘Contre Jour’ Comes to the Web with Internet Explorer 10

Game’s creator brings his vision to life with Internet Explorer’s immersive multitouch capabilities.

REDMOND, Wash. — Oct. 9, 2012 — After a busy summer with The Find, Pulse and Atari, Internet Explorer 10 today brings another well-known gaming experience to the Web in HTML5. The experience immerses users into a game rich with artistry and music, all while main character Petit – the one-eyed creature – seeks to save his love, The Rose. This world is “Contre Jour,” which is now available to play online as an interactive multitouch experience on the Web with Internet Explorer 10.

“Contre Jour” is not your typical game. Designed by Ukrainian developer Maksym (Max) Hryniv, the game draws many of its visual features, such as the use of black-and-white environment, from modern film noir titles such as “Sin City.” This design aesthetic is at the heart of the game. When making the decision to bring it to the Web, Hryniv was concerned whether it would really be possible. Assuming he could even build it, would any browser be capable of supporting the rich design, visual features and gameplay that requires multiple simultaneous touch gestures (i.e., multitouch)? After seeing Internet Explorer 10, the browser for Windows 8 that is leading the industry in its multitouch capabilities, he was willing to give it a try. (more…)

Berkeley Lab Researchers Develop New Tool for Making Genetic Engineering of Microbial Circuits Reliably Predictable

Synthetic biology is the latest and most advanced phase of genetic engineering, holding great promise for helping to solve some of the world’s most intractable problems, including the sustainable production of energy fuels and critical medical drugs, and the safe removal of toxic and radioactive waste from the environment. However, for synthetic biology to reach its promise, the design and construction of biological systems must be as predictable as the assembly of computer hardware. (more…)

UCLA Scientists Discover Sleeping Brain Behaves as If It’s Remembering Something

UCLA researchers have for the first time measured the activity of a brain region known to be involved in learning, memory and Alzheimer’s disease during sleep. They discovered that this region, called the entorhinal cortex, behaves as if it’s remembering something, even during anesthesia–induced sleep — a finding that counters conventional theories about sleep-time memory consolidation.
