Gorging on omega-3 fats lets birds get fit without exercise: study

It's a pity you're not a quail. Ottawa researchers have found that quails can boost their aerobic fitness just by sitting around and eating fats, provided they're the right kind.

The right kind happens to be omega-3 fatty acids, the same fats shown to reduce the risk of cardiovascular disease and lower blood pressure in humans.

After sedentary bobwhite quails were fed a supplement of omega-3 fatty acids for six weeks, their muscles showed a huge boost in the activity of enzymes that improve endurance compared to quails that didn't get the supplement, said a research paper published Friday in the Journal of Experimental Biology.

The same enzymes get more active and improve endurance in human athletes who train very hard for weeks, said University of Ottawa biologist Jean-Michel Weber, who conducted the study with his student Simba Nagahuedi.


US: Urban coyote attacks on rise, alarming residents

After a handful of recent attacks by coyotes in suburban Denver enclaves, officials are trying to keep the animals away from residents.
Denver - A coyote ambling into a Chicago sandwich shop or taking up residence in New York's Central Park understandably creates a stir. But even here on the high plains of Colorado, where the animals are part of the landscape and figure prominently in Western lore, people are being taken aback by rising coyote encounters.

Thanks to suburban sprawl and a growth in numbers of both people and animals, a rash of coyote encounters has alarmed residents.

Wildlife officials are working to educate the public: Coyotes have always been here, they've adapted to urban landscapes and they prefer to avoid humans.

"Ninety-five percent of this problem is a human problem, and we really need to focus on that 95 percent to solve it," said Nicole Rosmarino, wildlife program director of the environmental group WildEarth Guardians.

Earthquake rattles northern Peru

A moderate earthquake has occurred near the city of Piura in northern Peru but there were no immediate reports of casualties or damage.

The magnitude 5.8 quake struck at 1235 local time (1735 GMT), 85km (55 miles) to the south-west of the city of about 400,000 people.

The US Geological Survey estimated its depth to be 15.6km (9.7 miles).


Strong earthquake strikes off Japan

A strong 6.0-magnitude earthquake has struck off Japan's southern island of Okinawa, the US Geological Survey says.

The quake struck at 4:19am (local time), 165 kilometres north-west of Okinawa's capital Naha at a depth of 138 kilometres.

There were no immediate reports of casualties or damage.

About 20 per cent of the world's most powerful earthquakes strike Japan.


Another volcano in Alaska erupts?

This time it appears to be Mount Gareloi. Something big is going on there seismically. The webicorder is going nuts.

Update: I double checked the webicorder to see if it was still operating, and it appears to be. Still no word on the AVO website about the status of Gareloi.

Major Eruptions Continue at Mt. Redoubt

Alaska's Mount Redoubt continued its volcanic explosions Friday, sending ash clouds as high as 60,000 feet above sea level and prompting drivers to head to the auto parts store for new air filters. The National Weather Service said most of the ash was expected to fall to the north, but trace amounts of ash from eruptions on Friday and smaller ones overnight could fall on Anchorage itself.

Since the series of eruptions began Sunday night, the volcano has had several (actually closer to a dozen) bursts. One on Thursday sent ash 65,000 feet high. 5 eruptions followed Friday sending ash as high as 51,000 and 60,000 feet. The last time the volcano had erupted was during a four-month period in late 1989 and early 1990.


Drowning in the snows of Kotzebue Alaska

It's March now, how March should be-blue and sunny, twenty to thirty below in the morning with daytime highs rising to zero. Winter is slipping into memory, but we still have the drifts around Kotzebue to remind us.

January brought a longer-than-usual stretch of 30 and 40 below weather. We got restless, on the verge of cabin fever. We thought we deserved a break. Then the storms came, blizzards after blizzard--so often that we might as well have painted our windows white. Not that the paint would have stayed on.

Kotzebue is supposed to be stormy, but this year was more like drowning-we'd get a blow, and if we were lucky have a day to come up for air and shovel out, and then get hit with it again.


US: Frightened Fargo Watches as River Nears Top of Dike

Fargo, North Dakota - Residents here teetered between hope and fear after the Red River rose to record levels on Friday and threatened to overflow the city's dikes.

But the mayor of Fargo said Saturday he is "optimistic" about a new forecast saying the river may already have crested and could drop in the coming days.

The weather service had said earlier that the Red River could crest as high as 43 feet. But forecasters put out an alert Saturday saying the river is expected to remain below 41 feet and slowly decrease in the coming days.

Fargo Mayor Dennis Walaker said the city needs to continue to be diligent. But he said he is optimistic weary residents may have seen the worst after a long week of flood prevention.

A winter storm is expected to hit the region in the coming days, and Mr. Walaker acknowledged that the weather could change the flood outlook for the Red River. On Saturday, the National Weather Service said conditions seem to be improving and may not be as dire as originally expected.

Despite the forecast revision, North Dakota officials still intensified their efforts to fend off the floodwaters, deploying high-tech Predator drone aircraft, calling up more National Guard troops and asking residents to be on the lookout for any breaches in levees.

US: Vermont Bat Cave Devastated by Disease

Dorset - Spring has arrived on Mount Aeolus in Southern Vermont.

Bats are filtering out of a cave there by the minute.

But step inside and it's another story.

More than 20,000 dead bats are piled upon the cave's floor.

"It's pretty eerie and disturbing to say the least," said Ryan Smith of the U.S. Fish and Wildlife Dept. "You pretty much can't walk without stepping on them."
