Older Is Wiser: Study Shows Software Developers’ Skills Improve Over Time

There is a perception in some tech circles that older programmers aren’t able to keep pace with rapidly changing technology, and that they are discriminated against in the software field. But a new study from North Carolina State University indicates that the knowledge and skills of programmers actually improve over time – and that older programmers know as much (or more) than their younger peers when it comes to recent software platforms.

“We wanted to explore these perceptions of veteran programmers as being out of step with emerging technologies and see if we could determine whether older programmers are actually keeping up with changes in the field,” says Dr. Emerson Murphy-Hill, an assistant professor of computer science at NC State and co-author of a paper on the research. “And we found that, in some cases, veteran programmers even have a slight edge.” (more…)

Study Offers First Look at Green Sea Turtle Habitat Use in the Dry Tortugas

DRY TORTUGAS, Fla. – Nesting green sea turtles are benefiting from marine protected areas by using habitats found within their boundaries, according to a U.S. Geological Survey study that is the first to track the federally protected turtles in Dry Tortugas National Park.

Green turtles are listed as endangered in Florida and threatened throughout the rest of their range, and the habits of green sea turtles after their forays to nest on beaches in the Southeast U.S. have long remained a mystery. Until now, it was not clear whether the turtles made use of existing protected areas, and few details were available as to whether they were suited for supporting the green sea turtle’s survival.

Listening to the Big Bang – in high fidelity

A decade ago, spurred by a question for a fifth-grade science project, University of Washington physicist John Cramer devised an audio recreation of the Big Bang that started our universe nearly 14 billion years ago.

Now, armed with more sophisticated data from a satellite mission observing the cosmic microwave background – a faint glow in the universe that acts as sort of a fossilized fingerprint of the Big Bang – Cramer has produced new recordings that fill in higher frequencies to create a fuller and richer sound. (The sound files run from 20 seconds to a little longer than 8 minutes.) (more…)

A study of its basin paves the way for cleaner water everywhere

The Minnesota River’s usually placid surface belies its status as a river —and a watershed—in need of help.

The river is naturally prone to heavy sediment loads. It runs through rich glacial deposits, in a channel carved by a catastrophic flood at the end of the last ice age, when a large lake formed by glacial meltwater gave way. (more…)

In a significant advance for brain-machine interfaces, engineers at Brown University have developed a novel wireless, broadband, rechargeable, fully implantable brain sensor that has performed well in animal models for more than a year. They describe the result in the Journal of Neural Engineering and at a conference this week.

PROVIDENCE, R.I. [Brown University] — A team of neuroengineers based at Brown University has developed a fully implantable and rechargeable wireless brain sensor capable of relaying real-time broadband signals from up to 100 neurons in freely moving subjects. Several copies of the novel low-power device, described in the Journal of Neural Engineering, have been performing well in animal models for more than year, a first in the brain-computer interface field. Brain-computer interfaces could help people with severe paralysis control devices with their thoughts. (more…)

Big Jump in January Smartphone Adoption Driven Largely by Apple

RESTON, VA, March 6, 2013 – comScore, Inc., a leader in measuring the digital world, today released data from the comScore MobiLens service, reporting key trends in the U.S. smartphone industry during the three month average period ending January 2013. Apple ranked as the top smartphone manufacturer with 37.8 percent OEM market share, while Google Android led as the #1 smartphone platform with 52.3 percent platform market share.

Smartphone OEM Market Share

129.4 million people in the U.S. owned smartphones (55 percent mobile market penetration) during the three months ending in January, up 7 percent since October. Apple ranked as the top OEM with 37.8 percent of U.S. smartphone subscribers (up 3.5 percentage points from October). Samsung ranked second with 21.4 percent market share (up 1.9 percentage points), followed by HTC with 9.7 percent share, Motorola with 8.6 percent and LG with 7 percent (up 0.3 percentage points).

When it comes to evolution, humans can learn a thing or two from primeval sea lampreys.

In the current issue of Nature Genetics, a team of scientists has presented an assembly of the sea lamprey genome – the first time the entire sequence has been decoded. The data is compelling as the sea lamprey is one of the few ancient, jawless species that has survived through the modern era.

The paper not only sheds light on how the venerable invasive species adapted and thrived, but it also provides many insights into the evolution of all vertebrates, species with backbones and spinal cords, which includes humans, said Weiming Li, Michigan State University fisheries and wildlife professor, who organized and coordinated the team.
