BLOOMINGTON, Ind. -- While the contributions and value added by star performers can be extraordinary and even legendary, companies today often overlook the influence those top employees can have on others around them, according to new and previous research by an Indiana University Kelley School of Business management professor.

Writing in the journal Organizational Dynamics, Herman Aguinis, the John F. Mee Chair of Management and professor of organizational behavior and human resources, discusses how companies can effectively produce and manage star performers.

A new NASA study says that an increase in Antarctic snow accumulation that began 10,000 years ago is currently adding enough ice to the continent to outweigh the increased losses from its thinning glaciers.

The research challenges the conclusions of other studies, including the Intergovernmental Panel on Climate Change's (IPCC) 2013 report, which says that Antarctica is overall losing land ice.

HANOVER, N.H. - For millennia, Greenland's ice sheet reflected sunlight back into space, but satellite measurements in recent years suggest the bright surface is darkening, causing solar heat to be absorbed and surface melting to accelerate. Some studies suggest this "dirty ice" or "dark snow" is caused by fallout from fossil fuel pollution and forest fires.

NASA satellites have been providing data on powerful Tropical Cyclone Chapala as it continued strengthening in the Arabian Sea. The Global Precipitation Measurement Mission or GPM core satellite provided a look at strengthening Tropical Cyclone Chapala in the Arabian Sea. Additionally, NASA's Aqua satellite got a good look at the storm's small eye.

A team of astronomers is proposing that huge spiral patterns seen around some newborn stars, merely a few million years old (about one percent our sun's age), may be evidence for the presence of giant unseen planets. This idea not only opens the door to a new method of planet detection, but also could offer a look into the early formative years of planet birth.

Lab-based estimates of how worker productivity rubs off on peers are very similar to results from the field, a new report shows. The results come amid debate over the extent to which insights from lab experiments in the social sciences can be generalized to the field setting. Scientists debate the generalizability of lab findings in the social sciences for numerous reasons. Among them, they cite subjects tending to be students (and thus not representative of real world populations), and the controlled setting of lab studies, artificial in relation to actual workplaces.

Tropical Cyclone Chapala developed in the Arabian Sea on October 28 as the fourth tropical depression in the Northern Indian Ocean basin and on October 29, strengthened into a hurricane. NASA-NOAA's Suomi NPP satellite passed over Chapala and took a visible picture of the storm that showed it had become better organized over the 24 hour period and appeared to be developing an eye feature.

Scientists have catalogued nearly 2,000 exoplanets around stars near and far. While most of these are giant and inhospitable, improved techniques and spacecraft have uncovered increasingly smaller worlds. The day may soon come when astrophysicists announce our planet's twin around a distant star.

Spinning out? What you're able to take with you to your new company will determine how well you do

Toronto - To "spin out," you better have a big team with lots of experience.

When it comes to leaving a company to start your own, whether you sink or swim could depend on how many good people you can bring with you.

Researchers are sifting through an avalanche of data produced by one of the largest cosmological simulations ever performed, led by scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory.

Forget counting calories. The next new diet trend could be as simple as counting bites.

A new study from BYU health science researchers found people who counted bites over a month's time lost roughly four pounds--just about what the CDC recommends for "healthy" weight loss.

Those in the pilot test counted the number of bites they took each day and then committed to taking 20 to 30 percent fewer bites over the next four weeks. Participants who stuck with the task saw results despite changing nothing else about their eating and exercising routine.

TORONTO, ON - It's like something out of an interplanetary chess game. Astrophysicists at the University of Toronto have found that a close encounter with Jupiter about four billion years ago may have resulted in another planet's ejection from the Solar System altogether.

The existence of a fifth giant gas planet at the time of the Solar System's formation - in addition to Jupiter, Saturn, Uranus and Neptune that we know of today - was first proposed in 2011. But if it did exist, how did it get pushed out?

Observations led by astronomers at the University of Leeds have shown for the first time that a massive star, 25 times the mass of the Sun, is forming in a similar way to low-mass stars.

The discovery, made using a new state-of-the-art telescope called the Atacama Large Millimeter/submillimeter Array (ALMA), which is based in Chile, South America, is published online today by the Astrophysical Journal Letters.

In the face of decades of increasing temperatures and surface melting, the movement of the southwest portion of the Greenland Ice Sheet that terminates on land has been slowing down, according to a new study being published by the journal Nature on Oct. 29.

DURHAM, N.H. -- In a study published today in the Astrophysical Journal Letters, scientists from the University of New Hampshire and colleagues answer the question of why NASA's Voyager 1, when it became the first probe to enter interstellar space in mid-2012, observed a magnetic field that was inconsistent with that derived from other spacecraft observations.
