Scientists unravel ‘other’ malaria parasite’s DNA code

Scientists said Sunday they had unraveled the genetic codes of parasites responsible for the bulk of malaria cases outside Africa, and found they were scarily diversified and may be harder to kill. In a study published in Nature Genetics, researchers said they had sequenced the genomes of four strains of…

Study: Current heatwave likely to show global warming is ‘scientific fact’

A new study by the man called the “godfather of global warming” says there’s no getting around it: the heat wave pounding most of the country – and the world – is the result of man-made global warming. “This is not some scientific theory,” NASA scientist James Hansen told the…

Climate change to blame for extreme heat: NASA scientist

Human-driven climate change is to blame for a series of increasingly hot summers and the situation is already worse than was expected just two decades ago, a top NASA scientist said on Saturday. James Hansen, who directs the NASA Goddard Institute for Space Studies, wrote in the Washington Post that…

Are we alone? NASA’s Mars rover aims to find out

Are we alone? Or was there life on another planet? NASA’s $2.5 billion dream machine, the Mars Science Laboratory, aims to take the first steps toward finding out when it nears Mars’ surface on Monday. The planet is Earth’s closest neighbor, and scientists have found signs of water there, hinting…

Mass grave reveals how volcano caused global catastrophe

Scientists search for the explosive source of a disaster that wiped out almost a third of Londoners in 1258 When archaeologists discovered thousands of medieval skeletons in a mass burial pit in east London in the 1990s, they assumed they were 14th-century victims of the Black Death or the Great…

Mayans may have used chocolate in cooking 2,500 years ago

When the Spanish conquistadores invaded Mexico 500 years ago, they found the emperor Moctezuma drinking a exotic beverage called xocóatl with his breakfast. Made from ground cacao beans that had been boiled in water, spiced, and beaten to a froth, it was literally the drink of kings, permitted only to…

NASA scientists prepare for ‘seven minutes of terror’ in Mars rover landing

In the silence of space on the approach to Mars a US probe is warming up for an unprecedented act of theatre. Heaters aboard the spacecraft have begun to glow, thawing thrusters and components ahead of the most daring landing ever attempted on an alien world. Bearing down on the…

Toll in Uganda’s Ebola outbreak rises to 16: WHO

The latest outbreak of the deadly Ebola virus has killed 16 people in Uganda, the World Health Organization (WHO) said on Friday, increasing the previous toll by one. “Today we have 50 suspected cases and 16 dead,” WHO spokesman Tarek Jasarevic told reporters in Geneva. For the time being the…

Scientists treat ulcers with ‘spray-on skin’

Scientists said Friday they had developed a revolutionary “spray-on skin” treatment for venous leg ulcers — a common ailment involving a shallow, open and stubborn wound on the ankle or lower leg. Using a spray of skin cells suspended in a mixture of proteins that aid blood clotting, the team…

NASA confident ahead of nail-biter Mars landing

NASA said all was well ahead of its nail-biting mission to Mars, with its most advanced robotic rover poised to hunt for clues about past life and water on Earth’s nearest planetary neighbor. On a two-year journey to seek out signs of environments that once sustained life, the landing of…
