A Tailored Pair of Genes

Science

*For ancient plants, two genes were definitely better than one*

In the wake of the disaster that killed the dinosaurs, the ancestors of today’s crop plants reinvented themselves.

They doubled their genomes, and in that single act set the stage for feeding the world 60 million years later.

In a study published in the Nov. 16 issue of the journal Nature, researchers from the University of Minnesota and other institutions recount how sequencing the genome of a model, alfalfa-like legume revealed the monumental benefits that flowed when the ancestor of legumes acquired an extra copy of every gene.

MU Engineers Developing Military Applications for Smartphones

Technology, Weapons

COLUMBIA, Mo. – Tracking military targets? The University of Missouri’s College of Engineering has an app for that.

Engineers from the MU College of Engineering, with funding from the U.S. Army/Leonard Wood Institute, have enhanced popular smartphones to be able to find and track targets. In addition, the engineers have developed ad hoc networks so that soldiers can relay smartphone information without using the internet. (more…)

Focus on Testing Hurts Students in High School Health Classes

Education

COLUMBUS, Ohio – High school health classes fail to help students refuse sexual advances or endorse safe sex habits when teachers focus primarily on testing knowledge, a new study reveals.

But when teachers emphasized learning the material for its own sake, and to improve health, students had much better responses. In these kinds of classrooms, students had lower intentions of having sex and felt better able to navigate sexual situations.

“A focus on tests doesn’t help students in health classes make healthier choices,” said Eric M. Anderman, lead author of the study and professor of educational psychology at Ohio State University. (more…)

Len Peters: Preparing for the Technological Future

Technology

In a recent Town Hall meeting with staff in Information Technology Services (ITS) and IT partners from across campus, Yale’s Chief Information Officer Len Peters pointed out some of the technological changes that have taken place in the past 10 years — listing facts that might make some of today’s students think he was talking about an ancient world.

Just a decade ago, he noted, text messaging and smart phones weren’t being used on campuses (although nearly 70% of students had cell phones), and less than 30% of students had some form of wireless computer setup. (more…)
