Water in cells behaves in complex and intricate ways

ANN ARBOR — In a sort of biological “spooky action at a distance,” water in a cell slows down in the tightest confines between proteins and develops the ability to affect other proteins much farther away, University of Michigan researchers have discovered.

On a fundamental level, the findings show some of the complex and unexpected ways that water behaves inside cells. In a practical sense, they could provide insights into how and why proteins clump together in diseases such as Alzheimer’s and Parkinson’s. Understanding how proteins aggregate could help researchers figure out how to prevent them from doing so. (more…)

The Distance between a Mistake and a Lie

UA researcher Don Fallis has spent years studying the existence of lies and deception in social interactions and popular culture, developing a framework to better explain the difference between an honest mistake and an intentional lie.

Don Fallis searches for disinformation, the process of intentionally disseminating misleading information, in political dialogue, books, television and film – and he finds examples most everywhere.

That may come of little surprise, given the fictional nature of many entertainment-based cultural exchanges.

But for Fallis, a philosopher who studies social processes and information exchanges, the presence of disinformation – intentional lying, not honest mistakes or misinformation – allows for an important analysis of human tendencies, in fictional form or not. (more…)

ANN ARBOR — Although women drivers now outnumber male motorists, men still account for the majority of the driving on America’s roads—albeit at a declining rate, says a University of Michigan researcher.

Using data from the Federal Highway Administration, Michael Sivak, a research professor at the U-M Transportation Research Institute, examined changes in the gender demographics of U.S. drivers from 1963 to 2010. (more…)

Using new lensless imaging platform, team observes rare helical movements

A team of researchers from the UCLA Henry Samueli School of Engineering and Applied Science has, for the first time, directly recorded the three-dimensional helical swimming patterns of human sperm cells.

The team, led by Aydogan Ozcan, associate professor of electrical engineering and bioengineering, developed a novel lensless computational imaging platform that accurately tracked more than 24,000 individual sperm cells in a large volume. This involved observing the individual rotations of each sperm cell, including helical movement patterns, rotation speed, and linear and curved distances traveled. (more…)
