NEW YORK — For the first time, researchers have used the cloning technique that produced Dolly the sheep to create healthy monkeys, bringing science an important step closer to being able to do the same with humans.

NEW YORK — Some flowers have found a nifty way to get the blues.
They create a blue halo, apparently to attract the bees they need for pollination, scientists reported Wednesday. Bees are drawn to the colour blue, but it’s hard for flowers to make that colour in their petals.
NEW YORK — Five prominent species of ash tree in the eastern U.S. have been driven to the brink of extinction from years of lethal attack by a beetle, a scientific group says.
Tens of millions of trees in the U.S. and Canada have already succumbed, and the toll may eventually reach more than 8 billion, the International Union for Conservation of Nature said Thursday.
NEW YORK — If you learned your DNA made you more susceptible to getting a disease, wouldn’t you work to stay healthy?
You’d quit smoking, eat better, ramp up your exercise, or do whatever else it took to improve your odds of avoiding maladies like obesity, diabetes, heart disease or cancer, right?
The scientific evidence says: Don’t bet on it.
NEW YORK — Scientists are working to create yeast that operates with custom-made DNA.
They have long been able to make specific changes in an organism’s DNA. Now, they’re pushing into the more radical step of starting over, and building redesigned versions from scratch.
NEW YORK — At Jef Boeke’s lab, you can whiff an odour that seems out of place, as if they were baking bread here.
But he and his colleagues are cooking up something else altogether: yeast that works with chunks of man-made DNA.
NEW YORK — Matt Garlock has trouble making out what his friends say in loud bars, but when he got a hearing test, the result was normal. Recent research may have found an explanation for problems like his, something called “hidden hearing loss.”
NEW YORK — Federal researchers have created a new tool to clean up oil spills by tinkering with the kind of foam found in seat cushions.
The modified foam can soak up oil floating on water and lurking below the surface, and then can be repeatedly wrung out and reused, the researchers say.
NEW YORK — Pregnancy affects not only a woman’s body: It changes parts of her brain too, a new study says.
When researchers compared brain scans of women before and after pregnancy, they spotted some differences in 11 locations. They also found hints that the alterations help women prepare for motherhood.
NEW YORK — Why can tomatoes lose flavour in the fridge? A new study says it’s because some of their genes are chilling out. And that discovery might help scientists solve the problem.
