One of America's most widely planted crops — a genetically engineered corn plant that makes its own insecticide — may be losing its effectiveness because a major pest appears to be developing resistance more quickly than scientists expected.

The U.S. food supply is not in any immediate danger because the problem remains isolated. But scientists fear potentially risky farming practices could be blunting the hybrid's sophisticated weaponry.

A brainless, primeval organism able to navigate a maze might help Japanese scientists devise the ideal transport network design. Not bad for a mono-cellular being that lives on rotting leaves.

Amoeboid yellow slime mold has been on Earth for thousands of years, living a distinctly un-hi-tech life, but, say scientists, it could provide the key to designing bio-computers capable of solving complex problems.

This year was the hottest in France since the start of the 20th century, Meteo France said Tuesday, with average national temperatures 1.5 degrees Celsius warmer than the norm.

The average national temperature in 2011 was 13.6 degrees Celsius (56 degrees Fahrenheit), Meteo France's Francois Gourand told AFP, 0.2 degrees Celsius warmer than the previous hottest year, 2003.

The moon has come a long way since Galileo first peered at it through a telescope. Unmanned probes have circled around it and landed on its surface. Twelve American astronauts have walked on it. And lunar rocks and soil have been hauled back from it.

Despite being well studied, Earth's closest neighbor remains an enigma.

A new study says the 2007 cargo ship accident that dumped tens of thousands of gallons of oil into San Francisco Bay has caused lasting damage to the region's herring population.

The study released Monday found that Pacific herring embryos collected from shorelines left coated in oil after the Cosco Busan spill suffered unusually high death rates.

One of Indonesia's most active volcanoes erupted Tuesday, spewing clouds of ash and panicking villagers but no evacuation has been ordered so far, a government volcanologist said.

The first eruption at Mount Lokon was at 3:07 am (1907 GMT Monday), followed by two more bursts within minutes, Farid Bina told Agence France Presse from a monitoring post near the volcano on Sulawesi island.

China's home-grown satellite navigation system launched a limited positioning service Tuesday, the official Xinhua news agency said, as the country seeks to break its dependence on foreign technology.

China started building its space-based navigation network in 2000 to stop it having to rely on the U.S.-controlled Global Positioning System (GPS), and previous reports have said it will provide a worldwide service by 2020.

Cyanide fishing and rising water temperatures had decimated corals off Bali until a diver inspired by a German scientist's pioneering work on organic architecture helped develop a project now replicated worldwide.

Based on "Biorock" technology (http://www.globalcoral.org), it is implemented in 20 countries, mainly in Southeast Asia, the Caribbean, Indian Ocean and Pacific.

Japan's response to the nuclear crisis that followed the March 11 tsunami was confused and riddled with problems, including an erroneous assumption an emergency cooling system was working and a delay in disclosing dangerous radiation leaks, a report revealed Monday.

The disturbing picture of harried and bumbling workers and government officials scrambling to respond to the problems at Fukushima Dai-ichi nuclear power plant was depicted in the report detailing a government investigation.

Malaysian wildlife authorities said Monday the capture of a young female Borneo Sumatran rhino had given them a last chance to save the highly endangered species from extinction.

The female rhino, aged between 10 and 12 years old, was caught on December 18 and is being kept in the Tabin Wildlife Reserve in Sabah on the Malaysian area of Borneo island where it is hoped it will breed with a lone captive male.
