The Chinese scientist behind the world's biggest cloning factory has technology advanced enough to replicate humans, he told Agence France Presse, and is only holding off for fear of the public reaction.

Boyalife Group and its partners are building the giant plant in the northern Chinese port of Tianjin, where it is due to go into production within the next seven months and aims for an output of one million cloned cows a year by 2020.

Japan will resume "research" whaling in the Antarctic by the end of March next year, local media reported Saturday, despite a call by global regulators for more evidence that the expeditions have a scientific purpose.

In a martial artist's white silk pajamas, a man practiced tai-chi in harmony with a motorized arm at a Beijing exhibition showcasing a vision of robots with Chinese characteristics.

Vehicles with automated gun turrets sat alongside drink-serving karaoke machines at the World Robot Conference, as manufacturers sought new buyers for their "jiqiren" -- "machine people" in Chinese.

Forty minutes east of South Africa's capital Pretoria, amid the lowing of thousands of cows and the strong stink of dung, a small factory has taken on the challenge of turning manure into energy.

"Every day, 120 tonnes of manure and 66 tonnes of recycled paper are mixed in one of these tanks," Bio2Watt project manager Steven Roux said in the shadow of a looming 9,000 cubic meter vat.

The minuscule but nearly indestructible tardigrade gets a huge chunk of its genome from the DNA of foreign organisms, which scientists say may hold the key to its survival.

Also known as water bears, or moss piglets due to their morphology, these micro animals live all across the world.

A northern white rhinoceros -- one of just four remaining worldwide -- died Sunday at the San Diego Zoo, officials said.

The 41-year-old female known as Nola saw her health take a quick turn for the worse.

In fact, countries are at such odds over whether to do away with the "leap second" -- an extra second periodically added to compensate for irregularities in the earth's rotation around the sun -- that they have put off deciding the matter until 2023, the United Nations announced Thursday.

Country representatives gathered for a conference in Geneva hosted by the UN's International Telecommunication Union (ITU) have been haggling over the issue since the beginning of the month without reaching agreement.

In the middle of a desiccated lake bed in South Africa's North West province, a seven-month-old calf is too weak to get up. It is doomed to die from thirst and hunger.

A devastating drought is claiming thousands of livestock in Africa's most developed economy and prompting many to fear famine.

Since it awoke in August from a 138-year slumber, Ecuador's Cotopaxi volcano has become one of the most-watched in the world, holding wary locals and fascinated scientists in thrall.

Cotopaxi, whose snowy peak rises majestically from the patchwork quilt of central Ecuador's high plains, rumbled to life on August 14, belching a column of ash in its first major eruption since 1877.

French astronaut Thomas Pesquet will carry the text of any climate change deal clinched in Paris in December into space with him next year, a French junior minister for research said on Thursday.

"We truly hope to be able to give you the text of the final resolution," Thierry Mandon told a news conference in Paris, adding that he was still hopeful of an agreement next month despite "much uncertainty" surrounding the talks.
