Lariats: How RNA Splicing Decisions are Made

Lariats are discarded byproducts of RNA splicing, the process by which genetic instructions for making proteins are assembled. A new study has found hundreds more lariats than ever before, yielding new information about how splicing occurs and how it can lead to disease

PROVIDENCE, R.I. [Brown University] — Tiny, transient loops of genetic material, detected and studied by the hundreds for the first time at Brown University, are providing new insights into how the body transcribes DNA and splices (or missplices) those transcripts into the instructions needed for making proteins.

EL Wire Brightens Our World

Electroluminescence has come a long way since its discovery at the start of the 20^thcentury. For many years the scientists who pioneered its development struggled to come up with practical applications for electroluminescent technology – early uses of the discovery lacked the lifespan to work as practical lamps and light sources, whilst its unreliability made it difficult to use in displays and interfaces.

Undeterred by their setbacks, the boffins working on electroluminescence didn’t give up, and thank goodness, because today electroluminescent light has evolved into a technology that has myriad applications all over the planet. (more…)

HAWAI’I ISLAND, Hawai’i — The Hawaiian Islands’ largest atoll, French Frigate Shoals, is key to understanding how seabird nesting habitat will change with predicted rising sea levels, according to a team of U.S. Geological Survey biologists. (more…)

Researchers Find Gold Nanoparticles Capable of ‘Unzipping’ DNA

New research from North Carolina State University finds that gold nanoparticles with a slight positive charge work collectively to unravel DNA’s double helix. This finding has ramifications for gene therapy research and the emerging field of DNA-based electronics.

“We began this work with the goal of improving methods of packaging genetic material for use in gene therapy,” says Dr. Anatoli Melechko, an associate professor of materials science and engineering at NC State and co-author of a paper describing the research. Gene therapy is an approach for addressing certain medical conditions by modifying the DNA in relevant cells. (more…)

Carrots, Not Sticks, Motivate Workers

EAST LANSING, Mich. — What motivates people to work harder: The promise of reward or the threat of penalty?

A new study co-authored by a Michigan State University business scholar says it’s the carrot – and not the stick – that drives productivity.

The study, which appears in The Accounting Review, challenges previous research that says the threat of penalty is more effective for getting increased effort, said Karen Sedatole, associate professor of accounting in MSU’s Broad College of Business. (more…)

From the Mouths of Monkeys: New Technique Detects TB

Tuberculosis can be a serious threat to monkeys and apes. A new technique for detecting the tuberculosis -causing bacteria could help in protecting the health of primate populations. The method can spot TB even among infected primates that show no outward sign of disease, but are still capable of spreading infection to others of their kind. (more…)

Digital Media vs. Print Media

When you wake up in the morning, what’s one of the first things that you do? Do you head outside to pick the paper off the stoop, or do you hop online to see the latest news bits from overnight? Well, people still do both, but digital media is quickly becoming a very popular option.

Up-to-date Information

Sure, the newspaper tells you what is going on “now” in the general sense; however, the Internet can literally give you a play by play as a story is unfolding. People choose digital media because they can find out what is happening at that exact moment. Furthermore, they don’t have to wait for the newspaper to come; they can log on to the web at any time via a computer or smart phone. (more…)
