Climate change ‘likely to be more severe than some models predict’

Climate change is likely to be more severe than some models have implied, according to a new study which ratchets up the possible temperature rises and subsequent climatic impacts. The analysis by the US National Centre for Atmospheric Research (NCAR) found that climate model projections showing a greater rise in…

Collapse of Maya civilization tied to drought: study

WASHINGTON — A long catastrophic drought led to the collapse of Maya culture, a new study said Thursday, confirming a controversial hypothesis linking its demise to climate change. The study, published in Friday’s issue of the journal “Science,” involved an international team of researchers. “The rise and fall of Mayan…

Coral genomes under microscope in climate race

Researchers from Australia and Saudi Arabia launched a project Thursday which they hope will help them understand the genetic makeup of corals and how they react to climate change. Reefs around the world are under threat from bleaching due to climate change, as well as storms and predatory starfish, and…

Scientists ‘see’ through solid layers

PARIS — Scientists said Wednesday they have developed a method to “see through” layers of thin, solid material in a breakthrough that holds promise for medical imaging, nanotechnology — and the spy trade. Still in its infancy, the technique using laser and computer decoding has allowed a team from the…

Humans caused Great Barrier Reef collapse: study

The long-term collapse of the Great Barrier Reef off the coast of Australia can be directly attributed to farming runoffs from European settlements, a study published Tuesday claimed. The study, published in Tuesday’s edition of The Proceedings of the Royal Society B, is the first to connect soil and sediment…

Man made stone tools thousands of years earlier than previously thought

Paleontologists said Wednesday they have found small blades in a South African cave proving that Man was an advanced thinker making stone tools 71,000 years ago — millennia earlier than thought. The find suggests early humans from Africa had a capacity for complex thought and weapons production that gave them…

Chemists find a way to boost power of biofuels

Affordable fuel from grasses, trees and plant waste that packs enough of a punch to power a plane? Scientists said Wednesday this can be done using chemistry to boost basic fermentation processes. A team at the University of California in Berkeley said it had developed a method to add carbon…

Sick bird study could point to bird flu clues

House finches avoid sick members of their own species, scientists said in a finding that could be useful for tracking the spread of diseases like bird flu that also affects humans. Laboratory tests showed that the house finch, a particularly social North American species, was able to tell the difference…

Looking old linked to higher risk of heart attack

If you look old, you might be at higher risk of heart trouble. People with several visible signs of aging such as hair loss and fatty deposits around the eyes have a higher risk of developing heart problems than those of the same age who look younger, according to a…

Pet surgery could save human lives

Jon Henley: Many devoted pet owners are happy to spend thousands on operations for their cats and dogs – and these procedures could help teach scientists about human diseases, too If he could see himself now, Harry would be horrified. Slack-mouthed, out for the count, he has got drips going…
