'Missing' polar weather systems could impact climate predictions
Intense but small-scale polar storms could make a big difference to climate predictions according to new research from the University of East Anglia and the University of Massachusetts. Difficult-to-forecast polar mesoscale storms occur frequently over the polar seas, however they are missing in most climate models. Research published today in Nature Geoscience shows that their inclusion could paint a different picture of climate change in years to come. (2012-12-16)

Old pulsars still have new tricks to teach us
The super-sensitivity of ESA's XMM-Newton X-ray observatory has shown that the prevailing theory of how stellar corpses, known as pulsars, generate their X-rays needs revising. In particular, the energy needed to generate the million-degree polar hotspots seen on cooling neutron stars may come predominately from inside the pulsar, not from outside. (2006-07-26)

Polar bears unlikely to thrive on land-based foods
Polar bears, increasingly forced on shore due to sea ice loss, may be eating terrestrial foods including berries, birds and eggs, but any nutritional gains are limited to a few individuals and likely cannot compensate for lost opportunities to consume their traditional, lipid-rich prey -- ice seals. (2015-04-01)

Polar bear genome reveals rapid adaptation to fatty diet
Polar bears adapted to life in Arctic climates in part by relying on a high-fat diet mainly consisting of seals and their blubber. Researchers have discovered that mutations in genes involved in cardiovascular function allowed polar bears to rapidly evolve the ability to consume a fatty diet without developing high rates of heart disease. Moreover, the study revealed that polar bears diverged from brown bears less than 500,000 years ago -- more recently than previous estimates. (2014-05-08)

Scientists from the Max Planck Institute for Solar System Research in Katlenberg, Lindau, Germany, have now observed Saturn's polar region using the particle spectrometer MIMI, on the Cassini Space Probe. They discovered electrons not only being accelerated toward the planet, but also away from it. (2006-03-06)

Unprecedented Antarctic ice calls for twice the normal icebreaking muscle
A variety of natural factors, including the presence of an enormous iceberg dubbed B-15A, caused the sea ice near McMurdo Station, the National Science Foundation's logistical hub in Antarctica, to be far more extensive and much thicker during the 2001-2002 research season than previously recorded in the history of the U.S. Antarctic Program. (2002-03-12)

Study shows polar bear metabolic rates are higher than previously predicted
A new study on polar bear metabolism, behavior, and foraging success sheds important light on their energy demands. The study, published in the journal Science, found that polar bears have metabolic rates greater than previously predicted and greater than other terrestrial mammals of similar size. The study reinforces the understanding that polar bears are reliant on a diet of fat-rich seals to survive in the energetically-demanding Arctic. (2018-02-01)
