British researchers looking at the causes of chronic fatigue syndrome have received death threats from protesters angry at their focus on possible mental triggers, a report said Friday.

Several scientists researching the condition, which is also known as myalgic encephalomyelitis (ME), say they are being subjected to a campaign of harassment and abuse, the BBC reported.

Some 10 million people who inject illegal drugs have hepatitis C while 1.2 million have hepatitis B, according to the first global estimate of infection rates among this population, published Thursday.

An apple a day may keep the doctor away. But when you put it in a Happy Meal, it might help keep regulators at bay too. McDonald's on Tuesday said that it would add apple slices and reduce the portion of French fries in its children's meal boxes beginning this fall, effectively taking away consumers' current choice between either having apples with caramel dip or fries as a Happy Meal side.

The move by McDonald's, which has become a leader in moving from just burgers and fries to more nutritious fare like oatmeal and salads, comes as fast food chains face intense scrutiny from health officials and others who blame the industry for childhood obesity and other health-related problems. Some municipalities, including San Francisco, have even banned fast food restaurants from selling kids' meals with toys.

A lethal bat-borne horse virus has been detected in a dog for the first time, authorities in Australia said on Tuesday, prompting fears it has jumped species.

"This is the first time outside of a laboratory that an animal other than a flying fox or a horse, or a human, has been confirmed with Hendra virus infection," Queensland state Chief Veterinary Officer Rick Symons said.

Again and again, 12-year-old Brianna Bowens cautiously pokes the human eyeball. On purpose.

The donated eye is tougher than you'd think. It takes a few slices with a sharp scalpel to pierce the white part — the sclera, she learns — and eventually remove the cornea in front.

German pharmaceutical group Bayer said on Monday that its anti-coagulant drug Xarelto, also known as Rivaroxaban, had proved itself effective in preventing strokes in a Japanese study.
