To Cap or Not to Cap: Scientists Find New RNA Phenomenon That Challenges Dogma

COLUMBUS, Ohio – Some RNA molecules spend time in a restful state akin to hibernation rather than automatically carrying out their established job of delivering protein-building instructions in cells, new research suggests.

And instead of being a fluke or a mistake, the research suggests that this restful period appears to be a programmed step for RNA produced by certain types of genes, including some that control cell division and decide where proteins will work in a cell to sustain the cell’s life.

This could mean that protein production in cells is not as clear-cut as biology textbooks suggest, scientists say. (more…)

Haitians Struggle with the Costs Associated with Crime

ANN ARBOR, Mich.— As violent crime continues to rise in Haiti, more households are helping their children cope with the trauma as well as deal with burdensome funeral and burial costs, a new University of Michigan report indicated.

Violent crimes were more common in densely packed zones in Haiti’s largest urban communities, including Port-au-Prince, Les Cayes and Gonaives.

Researchers released the new survey that looks at the economic costs of violent crime in Haiti. The report is the second in a monthly series that features longitudinal surveys of 3,000 households from August 2011 and July 2012. (more…)

Supernovae of the Same Brightness, Cut From Vastly Different Cosmic Cloth

Berkeley Lab researchers make historic observation of rare Type 1a Supernova

Exploding stars called Type 1a supernova are ideal for measuring cosmic distance because they are bright enough to spot across the Universe and have relatively the same luminosity everywhere. Although astronomers have many theories about the kinds of star systems involved in these explosions (or progenitor systems), no one has ever directly observed one—until now. (more…)

3-D Mapping of Isaac Water Levels

A new technology is being deployed by U.S. Geological Survey scientists this weekend to map urban flooding caused by Hurricane Isaac. Called “terrestrial lidar,” or “T-lidar”, this new capability will enable scientists to collect highly detailed information in select population areas in Louisiana, Mississippi, and Alabama where the hurricane had the greatest impact.

The portable instrument allows scientists to quickly generate 3-D maps of buildings, dams, levees and other structures, and can show areas of storm damage as well. In a four-to-five minute scan, the instrument collects millions of topographic data points in a full 360-degree view to quickly produce highly accurate topographic information and can map areas up to two-thirds of a mile away.

Back to the Future: A New Science for a Changing Planet

In a world that is changing on a global scale and faster than ever before, science should rediscover its roots of observing the natural world unimpeded by the strict protocols of experimental manipulations, UA ecologist Rafe Sagarin and co-author Aníbal Pauchard suggest in their book, “Observation and Ecology.”

Mars rover Curiosity is doing it. School children strolling through the woods with binoculars are doing it. Charles Darwin was doing it. Observing the natural world around them was how the early naturalists started what would later become known as ecology – the science of how living things interact, depend on each other and how their habitats and communities change over time.

Computer Viruses Could Take a Lesson from Showy Peacocks

EAST LANSING, Mich. — Computer viruses are constantly replicating throughout computer networks and wreaking havoc. But what if they had to find mates in order to reproduce? (more…)

‘On the Road’

Synopsis

After his father’s death in the late 1940s, 24-year-old aspiring writer Sal Paradise meets 20-year-old ex-jailbird Dan Moriarty and his beautiful wife Marylou in New York. Dan is extremely charming and has a flexible moral code, and is as fascinated by Sal’s obsession with writing as Sal is by the unfettered freedom of his lifestyle. The two men spend intense nights of drinking, dreaming of another world, and forming a friendship that will take them on a trip across America. After staying at Bull Lees place in Louisiana, Sal, Dean, and Marylou continue traveling – naked and utterly enjoying themselves. (more…)

Rose McDermott: The Political Genome

A recent review of research co-authored by Rose McDermott highlights the role that genes play in political preferences, an area of study that began to draw significant attention in the last decade. McDermott speaks with Courtney Coelho about this growing field of research, its evolutionary roots, and whether it means anything for the prediction of future election results.

The connection between biology and political science is relatively new, but it’s one that has grown rapidly, with a boom in research linking genetics and political preferences in the last decade. Rose McDermott, professor of political science, has done research on this topic and recently co-authored a review, published in Trends in Genetics, of studies in recent years. (more…)
