Travelers in Alaska, Canada, the northern Plains, parts of the Midwest and much of the West tonight (Thursday) may be treated to a northern lights display more intense than usual because of the powerful solar storm hitting the Earth's surface, according to science and weather reports. The geomagnetic storm reached Earth about 5:45 a.m. EST Thursday. Scientists say the initial storm has been weaker than expected but may intensify later today. Northern lights trackers say tonight could bring a spectacular show to mid- and high latitudes in the Northern Hemisphere.

It's a little hard to remember that Americans once merely tolerated hops. Sierra Nevada was one of the pioneers in teaching us to enjoy the flavor, and a few years ago it produced this hoppy extreme, brewed with the fresh herb, harvested just 24 hours earlier. The effect is a startling burst of hop flavor, almost dank with heady, resinous aroma. It's a seasonal brew, so it will go out of stock, but good news: Sierra Nevada will produce another Harvest Lager (Southern Hemisphere) in about six months.

If you don't believe in horoscopes, you're in step with science. But that's not the same as saying the season of your birth cannot affect your fate. Hundreds of studies, published in peer-reviewed journals, have suggested that the month a person is born in is associated with characteristics such as temperament, longevity and susceptibility to certain diseases. Scientists say that even though some of these findings are probably spurious - if you dig around in data, you will eventually find correlations just by chance - other effects are very likely real, triggered not by the alignment of the planets but by exposures during prenatal and early postnatal lives.

Tyrannosaurs may have stalked far more of the globe than previously thought. Scientists for the first time have found evidence of an ancestor of Tyrannosaurus rex in the Southern Hemisphere, a discovery that could shed light on tyrannosaurs' evolutionary lineage, which many scientists had thought was restricted to the Northern Hemisphere after the continents began to separate. Tyrannosaurs had been documented only in Asia, Europe and North America, but a hip bone discovered in Australia could have come only from a tyrannosaur, researchers have concluded.

IT'S NOT JUST NATURE THAT abhors a vacuum; man does too. That sucking sound you hear is the noise made by thousands of young immigrants as they travel from the overpopulated Southern Hemisphere to the more prosperous Northern Hemisphere in pursuit of employment. The phenomenon is putting pressure on economies from Oslo to Okinawa, and it is fueling raucous worldwide debates about immigration and motherhood.

The north and south poles on Mars look very different from each other, and scientists now think they know why: Circulation patterns in the Red Planet's very thin atmosphere tend to keep all the water in the north, leaving the south pole high and dry. The exploration of Mars by unmanned spacecraft has shown that the northern hemisphere has a large polar cap made up mostly of frozen water while the southern hemisphere has a much smaller cap made up...
