Science Researchers Battle on in DR Congo Conflict Zones

"That day, we were almost in mourning," said Luc Bagalwa, a geophysics researcher in the eastern Democratic Republic of Congo, recalling the 2002 eruption of the Nyiragongo volcano.

While the ash and deep lava destroyed part of the northeastern city of Goma and prompted the evacuation of hundreds of thousands of people, the recording apparatus in Bagalwa's laboratory had no paper to note the spectacular seismic events.

Russia to Resume Space Tourism in 2018

Russia officials say they will resume space tourism in 2018 after years of sending into space only professional cosmonauts and astronauts.

Russia had sent seven paying guests to the International Space Station since 2001 before curtailing the program in 2009. Sending a tourist has been all but impossible since 2011 when the United States shut down its Space Shuttle program and had to rely on Russian Soyuz rockets in order to get into orbit.

Tokyo Aquarium Baffled by Mystery Fish Deaths

Workers at a Tokyo aquarium are scratching their heads after the deaths of dozens of fish that have left just one lonely tuna roaming a once-flourishing tank.

The park on Tuesday found the second last fish floating dead in its vast doughnut-shaped enclosure that was once home to nearly 160 fish and among the venue's most popular attractions, said a spokesman for Tokyo Sea Life Park.

India's Frugal Mars Mission Extended by Six Months

India's famously frugal Mars mission has been extended by around six months thanks to a surplus of fuel on board the spacecraft, the country's space agency said Tuesday.

The Mars Orbiter Mission spacecraft had been scheduled to wrap up its mission this month after India in September became the first Asian nation to reach the Red Planet, all on a shoe-string budget.
