Mexico’s Senate passes climate change bill

Mexico’s Senate has unanimously passed a climate change bill aimed at reducing carbon emissions by 50 percent by 2050, following Britain in creating legally binding emissions goals. The law — approved late Thursday and which still needs to be signed by President Felipe Calderon — seeks to promote policies and…

Scientists create artificial genetic material XNA

Scientists have created artificial genetic material that can store information and evolve over generations in a similar way to DNA – a feat expected to drive research in medicine and biotechnology, and shed light on how molecules first replicated and assembled into life billions of years ago. Ultimately, the creation…

Polar bears older than previously thought: study

Polar bears diverged from their closest relatives 600,000 years ago, far earlier than previously thought, suggesting more challenges in the face of climate change, scientists said. Previous genetic analysis of polar bears had determined the species was only about 150,000 years old. But in fact, it took them five times longer for the…

AIDS experts launch ‘CNN of virology’ in Canada

A new digital media service will foster the global collaboration of physicians and help them to share the latest advances in AIDS and other virus research, according to its Canadian promoters. The new bilingual French and English service, “viroXchange,” is funded by large pharmaceutical companies but will provide “independent” reporting on the…

Scientists create DNA alternative

Artificial genetic material – XNAs – expected to reveal how molecules first replicated and drive biotechnology research Scientists have created artificial genetic material that can store information and evolve over generations in a similar way to DNA – a feat expected to drive research in medicine and biotechnology, and shed…

Nearly 60 archeological sites unearthed near Rio

RIO DE JANEIRO, Brazil — Nearly 60 archeological sites dating back 6,000 years have been unearthed during construction of a road near Rio, an archaeologist said Thursday. “Last week, we found a small stone well dating back to the (Portuguese) colonial period with clear water and we stopped work,” said…

‘Holy grail’ gene mapping gives hope to breast cancer victims

By David Batty, guardian.co.uk The treatment of breast cancer could be revolutionised with patients offered more accurate diagnoses and better-targeted treatments after a study in which scientists genetically mapped the disease. The research found that rather than being a single disease, breast cancer can be classified into 10 distinct types.…

Phone calls back evolutionary theories of gender

PARIS — Women speak to their male partners less often as they grow older and turn their attention to a younger generation, according to an unusual study Thursday that tracked nearly two billion phone calls and text messages. The findings back evolutionary theory about the role of women in the…

China ‘river pig’ deaths raise extinction fears

China says 16 endangered finless porpoises have been found dead since the beginning of the year and experts blame water pollutionand climate change for pushing the species toward extinction. The freshwater porpoise — popularly known in Chinese as the “river pig” — mainly lives in China’s Yangtze River and two lakes linked to the waterway. Authorities…

U.S. oil boom fuels earthquake rise – but fracking not to blame, scientists say

America’s oil and natural gas boom has led to a “remarkable” rise in earthquakes in the middle of the country, the US Geological Survey said on Wednesday. But scientists said the man-made quakes were not directly caused by hydraulic fracturing, or fracking, which involves pumping chemicals and water deep into…
