Scientists have found three glaciers in Toyama Prefecture, the first recognized in Japan and the southernmost in East Asia.

Tateyama Caldera Sabo Museum discovered the three slow-moving chunks of ice in the Hida Mountain Range, otherwise known as the Northern Alps.

Their research paper submitted to the Japanese Society of Snow and Ice was accepted Tuesday, the museum said.

A glacier is defined as a large mass of ice that over many years "flows" owing to its great weight, according to the Japanese Society of Snow and Ice. They are often found on high mountains, such as the Himalayas, and have even been found on Mount Kilimanjaro, which is almost on the equator. Until now, the southernmost glaciers in East Asia were on Russia's Kamchatka Peninsula.

"We have known something similar to glaciers existed, so we checked to see if the masses of ice are moving," said Hajime Lida, a researcher for the museum.

Death toll rises to fifteen in Buenos Aires City and Province as the region recovers from a heavy storm that hit the area on Wednesday night taking porteños by surprise after an unusual warm day for the season.

Intense rain and hail storms caused death and destruction throughout the country and mainly in the Buenos Aires province and Capital area. Over 500 people had to be evacuated. Estimates of the damage caused suggested a figure of several million pesos' worth.

According to officials, four people died in Buenos Aires City. One person was killed when a wall collapsed, while three others were perished after a roof collapsed in Villa 21 shantytown. The ten victims died in the province: four in Moreno, one in Quilmes, one in Florencio Varela, one in Isidro Casanova, one in Gonnet, one in Flores and another in Avellaneda.

Most of the victims were crushed by toppled walls, fallen roofs or blown trees.

Victim number fifteen was confirmed this morning at Villa Soldati neibourhood. Bertilio Alarcón worked for the gendarmerie when his station was hit and dragged by the strong winds.

As bee populations continue to decline, researchers are scurrying to try and find an answer as to why.

A new study from Harvard School of Public Health has linked one of the most widely used pesticides, imidacloprid, as the bee's nemesis.

The authors wrote in a paper being published in the Bulletin of Insectology that they have found "convincing evidence" of the link between imidacloprid and Colony Collapse Disorder (CCD), in which adult bees abandon their hives.

"The significance of bees to agriculture cannot be underestimated," Alex Lu, associate professor of environmental exposure biology in the Department of Environmental Health, said in a press release. "And it apparently doesn't take much of the pesticide to affect the bees. Our experiment included pesticide amounts below what is normally present in the environment."

The team conducted a study in Worcester County, Massachusetts to try and replicate how imidacloprid may have caused the CCD outbreak.

They monitored bees in four different bee yards, each of which had four hives treated with different levels of imidacloprid and one control hive.

Wildlife experts are studying whether fur loss and open sores detected in nine polar bears in recent weeks is widespread and related to similar incidents among seals and walruses.

The bears were among 33 spotted near Barrow, Alaska, during routine survey work along the Arctic coastline. Tests showed they had "alopecia, or loss of fur, and other skin lesions," the U.S. Geological Survey said in a statement. "The animals were otherwise healthy in appearance and behavior."

Blood and tissue samples were collected from the sedated polar bears to see if the symptoms are related to those seen in ringed seals and walruses.

Patchy hair loss has been seen before in polar bears, but the high prevalence in those spotted recently and the earlier seal and walrus incidents raise a concern, Reuters quoted Tony DeGange, the chief biologist for the USGS in Alaska, as saying.

"There's a lot we don't know yet," he said, "whether we're dealing with something that's different or something that's the same."

Thousands of dead or dying dolphins have washed ashore in Peru since January, a marine mystery potentially caused by a combination of stress, pollution and disease.

When a retired fisherman called to report that about 1,500 dolphins had washed up dead on Peru's northern coast, veterinarian Carlos Yaipén's first reaction was, "That's impossible."

But when Yaipén traveled up the coast last week, he counted 615 dead dolphins along a 135-kilometer stretch of coastline.

Now, the death toll could be as high as 2,800, based on volunteers' counts. Peru's massive dolphin die-off is among the largest ever reported worldwide.

The strandings, which began in January, are a marine mystery that may never be unraveled. Experts say the causes could be acoustic impact from testing for oil or perhaps an unknown virus or other pathogen. Little marine research takes place in Peru, and even in the United States, of 55 marine mammal strandings since 1991, the National Oceanographic and Atmospheric Administration (NOAA) has classified 29 as "undetermined."

Kelp off Southern California was contaminated with short-lived radioisotopes a month after Japan's Fukushima accident, a sign that the spilled radiation reached the state's coastline, according to a new scientific study. Scientists tested giant kelp from the ocean off Orange County and other locations after the March, 2011 accident and detected radioactive iodine at peak concentrations 250-fold higher than levels found in West Coast kelp before the nuclear accident. "Basically we saw it in all the California kelp blades we sampled," said biology professor Steven Manley of California State University, Long Beach. The radioactivity had no known effects on the giant kelp, or on fish and other marine life, and it was undetectable when the kelp was tested again a month later. Iodine 131 "has an eight-day half life so it's pretty much all gone," Manley said. "But this shows what happens half a world away does effect what happens here. I don't think these levels are harmful but it's better if we don't have it at all."

Kelp off Southern California was contaminated with short-lived radioisotopes a month after Japan's Fukushima accident, a sign that the spilled radiation reached the state's urban coastline, according to a new scientific study.

Scientists from California State University, Long Beach tested giant kelp collected in the ocean off Orange County and other locations after the March, 2011 accident, and detected radioactive iodine, which was released from the damaged nuclear reactor.

The largest concentration was about 250-fold higher than levels found in kelp before the accident.

"Basically we saw it in all the California kelp blades we sampled," said Steven Manley, a Cal State Long Beach biology professor who specializes in kelp.

The radioactivity had no known effects on the giant kelp, or on fish and other marine life, and it was undetectable a month later.

Iodine 131 "has an eight-day half life so it's pretty much all gone," Manley said. "But this shows what happens half a world away does effect what happens here. I don't think these levels are harmful but it's better if we don't have it at all."

A year ago, Manley watched coverage of the tsunami and Fukushima accident and wondered what impact it might have on California's marine life, particularly his favorite subject matter - kelp.

Spread in large, dense, brown forests across the ocean off California, Macrocystis pyrifera, known as giant kelp, is the largest of all algae and grows faster than virtually any other life on Earth. It accumulates iodine so Manley realized it would be a useful dosimeter to check how far radioactive material spreads.

"Kelp forests are some of the most productive ecosystems on Earth," he said. "I thought this would be an opportunity because one thing about macrocystis is it has a large surface canopy," which means it is continually exposed to the air - and whatever contaminants are in it.

In addition, giant kelp concentrates radioactive iodine 10,000-fold - for every one molecule in the water there would be 10,000 in its tissues.

Kelp was collected at three sites off Orange County, as well as Palos Verdes Peninsula in Los Angeles County, Santa Barbara, Pacific Grove and Santa Cruz. The highest concentration of iodine 131 was found in the kelp off Corona del Mar, which receives runoff from a large portion of Orange County. Its kelp was collected on April 15 of last year and tested five days later.

More than 130 large dams built, under construction, or proposed in western China's seismic hazard zones could trigger disastrous environmental consequences such as earthquakes and giant waves, finds a new report from the Canadian watchdog group Probe International.

The report shows that 98.6 percent of the dams being constructed in western China are located in high to moderate seismic hazard zones.

The location of large dams near clusters of recorded earthquakes with magnitudes greater than 4.9, and especially when the earthquake focal points are also close to the surface, "is cause for grave concern," said the report's author geologist "John Jackson."

John Jackson is a pseudonym for a geologist with detailed knowledge of western China who wishes to remain anonymous to protect his sources.

In a worst-case scenario, Jackson reports, dams could collapse, creating a giant wave that would inundate everything in its path, including downstream dams, causing great loss of life and property.

Mystery surrounds the appearance of more than a hundred dead catfish washed up at the Boyne River Mouth.

Residents have been finding the fish since Monday. Along the high tide line on Boyne Island, dead catfish were strewn every few metres along the high tide line from the morning before.

A spokesperson from the Department of Environment and Heritage Protection (DEHP) confirmed staff had inspected a section of the Boyne River on Monday and yesterday following reports of dead fish.

"Departmental staff have found over 100 dead catfish between the mouth of the Boyne River and the Bruce Highway bridge, approximately 20 kilometres south of Gladstone.

"The cause of death is currently unknown. Departmental staff are investigating and have conducted water quality monitoring and sampling.

"The water quality monitoring undertaken on 4 April 2012 identified reduced salinity levels due to freshwater inflow. All other monitoring results have found water quality is consistent with those of a healthy waterway."

The circumstances that ended the last ice age, somewhere between 19,000 and 10,000 years ago, have been unclear. In particular, scientists aren't sure how carbon dioxide, a greenhouse gas, played into the giant melt.

New research indicates it did in fact help drive this prehistoric episode of global warming, even though it did not kick it off. A change in the Earth's orbit likely started of the melt, setting off a chain of events, according to the researchers.

The ambiguity about the end of the ice age originates in the Antarctic. Ice cores from the continent reveal a problematic time lag: Temperatures appeared to begin warming before atmospheric carbon dioxide increased. This has led scientists to question how increasing carbon dioxide - a frequently cited cause for global warming now and in the distant past - factored into the end of the last ice age. Global warming skeptics have also cited this as evidence carbon dioxide produced by humans is not responsible for modern global warming.

But the data from Antarctica alone offer too narrow a perspective to represent what was happening on a global scale, according to lead study researcher Jeremy Shakun of Harvard University.

"These ice cores only tell you about the temperatures in Antarctica where they are from, and if you think about today the same way, you don't want to look at one thermometer record from London or New York to prove or disprove global warming," Shakun said during a press conference on Tuesday (April 3).
