Three people, including two teenagers, were killed and five injured, when they were struck by lightning in the Russian Volga Republic of Bashkortostan, a local emergencies spokesman said on Thursday.
Re-seeding programmes on over 50 reefs are securing the survival of the giant clam for at least another generation, according to World Wildlife Fund-Philippines.
The clams, the world's largest bivalve mollusks and the star of lurid but mostly imaginary literary and cinematic depictions of trapped divers, can live for over a century. They have been known to exceed 1.4 metres in length and weigh in at over 260 kilograms.
Once common throughout Philippine reefs, excessive hunting for the food, pet and curio trade all but depleted the wild giant clam population by the mid-1980s, prompting the IUCN to classify them as vulnerable.
An attempt to restore natural clam populations is now being spearheaded by Dr. Suzanne Mingoa-Licuanan of the University of the Philippines Marine Science Institute in partnership with World Wildlife Fund-Philippines.

MEXICO CITY - Tropical storm Fausto formed off the Mexican resort city of Acapulco on Wednesday, while Elida strengthened to a Category 2 hurricane far away from Baja California's coast.
Neither storm was expected to threaten land. Fausto was moving west away from land at 26 km/h, according to the National Hurricane Center in Miami. It was located about 625 kilometres south of Acapulco with winds reaching 65 km/h.

For the first time, researchers have taken a detailed look at what lies beneath all of Iceland's volcanoes - and found a world far more complex than they ever imagined.
They mapped an elaborate maze of magma chambers - work that could one day help scientists better understand how earthquakes and volcanic eruptions occur in Iceland and elsewhere in the world.
Knowing where magma chambers are located is a key first step to understanding the chemical composition of the molten rock that is flowing within them - and of the gases that are released when a volcano erupts, explained Daniel Kelley, doctoral student in earth sciences at Ohio State University.

A group of scientists has used deep ocean-floor drilling and experiments to show that volcanic rocks off the West Coast and elsewhere might be used to securely imprison huge amounts of globe-warming carbon dioxide captured from power plants or other sources.
In particular, they say that natural chemical reactions under 78,000 square kilometers (30,000 square miles) of ocean floor off California, Oregon, Washington and British Columbia could lock in as much as 150 years of U.S. CO2 production. The findings are published today in the Proceedings of the National Academy of Sciences.
Interest in so-called carbon sequestration is growing worldwide. However, no large-scale projects are yet off the ground, and other geological settings could be problematic. For instance, the petroleum industry has been pumping CO2 into voids left by old oil wells on a small scale, but some fear that these might eventually leak, putting gas back into the air and possibly endangering people nearby.

Storm Kalmaegi has gained momentum as it approaches Taiwan, threatening the island's east, the Central Weather Bureau said Wednesday.
The edge of the storm may hit eastern Taiwan and unleash downpours in the east and north, an official at the bureau said.
"Ships sailing on the Bashih Channel and waters east of Taiwan must heighten their vigilance," the official said.
The storm was 370 kilometres (222 miles) southeast of Oluanpi, the island's southernmost tip, at 5:00 pm (0900 GMT).

Humans could learn much about health, public transport and peaceful living by observing the behaviour of bees, the leader of Britain's first bee-keeping research lab has claimed.

The mountain pine beetle isn't the only problem British Columbia forest officials are concerned about in the Southern Interior.
Entomologist Lorraine MacLauchlan, who just came back from the field, says the area is in the midst of a severe outbreak of the tussock moth.

Bats are a remarkable evolutionary success story representing the second largest group of mammals, outnumbered only by rodents in number of species. Now, researchers of the Leibniz-Institute for Zoo and Wildlife Research in Berlin (Germany) and Boston University (U.S.A.) have discovered the place that harbours the highest number of bat species ever recorded. In a few ha* of rainforest in the Amazon basin of eastern Ecuador, the authors have found more than 100 species of bats.
Dr. Katja Rex and colleagues captured bats at several biodiversity hotspots in the New World tropics, in the lowland rainforest of Costa Rica, the slopes of the Andes and a site in the Amazon rainforest of Eastern Ecuador, at the Tiputini Biodiversity Station 1 located adjacent to the Yasuní Biosphere Reserve. During many months of strenuous nightly field work, exposed to rain and mosquitoes, the researchers captured bats, identified species and recorded the total number of each species they captured. Based on these numbers, they calculated the species richness and diversity present in each of these forests.
