Deep Oceans May Mask Global Warming for Years at a Time

*Computer simulations of global climate lead to new conclusions*

Earth’s deep oceans may absorb enough heat at times to flatten the rate of global warming for periods of as long as a decade–even in the midst of longer-term warming. This according to a new analysis led by scientists at the National Center for Atmospheric Research (NCAR).

The study, based on computer simulations of global climate, points to ocean layers deeper than 1,000 feet as the main location of the “missing heat” during periods such as the past decade when global air temperatures showed little trend. (more…)

Companies can take advantage of state-of-the art equipment; students gain experience

COLUMBIA, Mo. – When Microdyne, LLC, needed help building a prototype for a dairy cattle breeding device, the company, based in St. Joseph, was ready to look overseas for a prototype manufacturing team. Then Microdyne was introduced to Mike Klote, manager of the University of Missouri’s College of Engineering prototype development facility, and a solution was found that also provided MU engineering students a valuable educational opportunity.

To Ditch Dessert, Feed the Brain

Science

If the brain goes hungry, Twinkies look a lot better, a study led by researchers at Yale University and the University of Southern California has found.

Brain imaging scans show that when glucose levels drop, an area of the brain known to regulate emotions and impulses loses the ability to dampen desire for high-calorie food, according to the study published online September 19 in The Journal of Clinical Investigation. (more…)

NASA’s WISE Mission Captures Black Hole’s Wildly Flaring Jet

Science

PASADENA, Calif. — Astronomers using NASA’s Wide-field Infrared Survey Explorer (WISE) have captured rare data of a flaring black hole, revealing new details about these powerful objects and their blazing jets.

Scientists study jets to learn more about the extreme environments around black holes. Much has been learned about the material feeding black holes, called accretion disks, and the jets themselves, through studies using X-rays, gamma rays and radio waves. But key measurements of the brightest part of the jets, located at their bases, have been difficult despite decades of work. WISE is offering a new window into this missing link through its infrared observations. (more…)

‘Buyer Beware: Advertising May Seduce Your Brain’

Technology

Are you wooed by advertising? Of course you are. After all, it’s one thing to go out and buy a new washing machine after the old one exploded, quite another to impulse-buy that 246-inch flat screen TV that just maybe, in hindsight, you didn’t really need. (more…)

Origin of Dinosaur-Killing Asteroid Remains a Mystery

Science

PASADENA, Calif. — Observations from NASA’s Wide-field Infrared Survey Explorer (WISE) mission indicate the family of asteroids some believed was responsible for the demise of the dinosaurs is not likely the culprit, keeping open the case on one of Earth’s greatest mysteries.

While scientists are confident a large asteroid crashed into Earth approximately 65 million years ago, leading to the extinction of dinosaurs and some other life forms on our planet, they do not know exactly where the asteroid came from or how it made its way to Earth. A 2007 study using visible-light data from ground-based telescopes first suggested the remnant of a huge asteroid, known as Baptistina, as a possible suspect. (more…)

Better Ways to Hire, Announce a New CEO

Economy

*Two studies by a UA business professor examine the hiring of CEOs, finding that new CEOs make better decisions when their self image is tied to the firm and that “strategic noise” can soften market response to a new hire.*

Two new papers co-authored by assistant professor of management Steven Boivie at the University of Arizona uncover novel facets of CEO and firm performance.

The first of the papers, out now in the Academy of Management Journal, finds a new remedy to the CEO agency problem. Instead of trying to design incentives and controls to keep corporate leaders acting in the best interest of the company, Boivie and his co-authors demonstrate that boards should try to hire leaders who strongly identify with the company itself.
