Could a Milky Way supernova be visible from Earth in next 50 years?

November 1, 2013 8:05 am | News | Comments

Astronomers have calculated the odds that, sometime during the next 50 years, a supernova occurring in our home galaxy will be visible from Earth. The good news: They’ve calculated the odds to be nearly 100% that such a supernova would be visible to telescopes in the form of infrared radiation. The bad news: The odds are much lower that the shining stellar spectacle would be visible to the naked eye in the nighttime sky.

Byrd came close, but probably didn’t reach North Pole

April 8, 2013 6:02 pm | by Pam Frost Gorder, OSU | News | Comments

When renowned explorer Richard E. Byrd returned from the first-ever flight to the North Pole in 1926, he sparked a controversy that remains today: Did he actually reach the pole? Studying supercomputer simulations of atmospheric conditions on the day of the flight and double-checking Byrd’s navigation techniques, a researcher at Ohio State University has determined that Byrd neared the Pole, but did not reach it.

Simulations uncover obstacle to harnessing laser-driven fusion

March 27, 2013 7:50 am | News | Comments

A once-promising approach for using next-generation, ultra-intense lasers to help deliver commercially viable fusion energy has been brought into serious question by new experimental results and first-of-a-kind simulations of laser-plasma interaction. So-called fast ignition, this process involves a long-discussed possibility of using a hollow cone to help focus laser energy on the pellet core to induce fusion. Unfortunately, these cones appear to fail in that mission.

Researchers find new way for plants to pass traits to next generation

March 26, 2013 12:50 pm | by Emily Caldwell, Ohio State University | News | Comments

Scientists have shown that an enzyme in corn responsible for reading information from DNA can prompt unexpected changes in gene activity—an example of epigenetics that breaks accepted rules of genetic behavior. Though some evidence has suggested that epigenetic changes can bypass DNA’s influence to carry on from one generation to the next, this is the first study to show that this epigenetic heritability can be subject to selective breeding.

New factor could limit life of hybrid and electric car batteries

December 13, 2012 8:02 am | News | Comments

A new study of the batteries commonly used in hybrid and electric-only cars has revealed an unexpected factor that could limit the performance of batteries currently on the road. Researchers led by Ohio State University engineers examined used car batteries and discovered that over time lithium accumulates beyond the battery electrodes—in the "current collector," a sheet of copper which facilitates electron transfer between the electrodes and the car's electrical system.

DNA analysis of microbes in a fracking site yields surprises

December 3, 2012 3:15 pm | by Pam Frost Gorder, Ohio State University | News | Comments

Researchers have made a genetic analysis of the microbes living deep inside a deposit of Marcellus Shale at a hydraulic fracturing. They expected to find many tough microbes, such as single-celled archaea, suited to extreme environments. Instead, they found very few genetic biomarkers for archaea, and many more for species that derive from bacteria.They also found that the populations of microbes changed dramatically over a short period of time.

Butterfly wings inspire new high-tech surfaces

November 7, 2012 2:33 pm | by Pam Frost Gorder, Ohio State University | News | Comments

After carefully studying the structure of butterfly wings and rice leaves, Ohio State University engineers designed a coated plastic surface resembling a butterfly wing’s texture. Butterflies in the wild need to have bright, clean wings for reproduction and flying, and the surface created by engineers was reportedly easier to keep free of dust particles than a flat surface. The finding could inform designs for a variety of surfaces in various industries.

Scientists discover RNA phenomenon that challenges dogma

August 27, 2012 10:50 am | News | Comments

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. This restful period appears to be a programmed step for RNA produced by certain types of genes. Protein production in cells is not as clear-cut as biology textbooks suggest, scientists say.

Genetically engineered algae for biofuel pose potential risks

August 20, 2012 8:53 am | News | Comments
