A female British healthcare worker who contracted Ebola in Sierra Leone was being flown home for treatment on Thursday, the Ministry of Defense said.

A Royal Air Force plane sent to the west African country on Wednesday is bringing the military servicewoman back to be treated in London's Royal Free Hospital, an MoD spokeswoman said.

An experimental, non-invasive technique using targeted ultrasound has shown promise in lab animals toward eliminating the brain plaques that cause Alzheimer's disease, an incurable form of dementia, researchers said Wednesday.

Tests on mice showed the approach -- using sound waves to penetrate tissue much the same way as ultrasounds are used to detect fetal shape and movement in pregnant women -- eliminated almost all amyloid plaque in 75 percent of the animals studied, without damaging brain tissue, according to the study in the U.S. journal Science Translational Medicine.

Part of their vision to establish a healthy and educated community, cancer patient support groups announced at the UNESCO Palace winners of their ‘Know to Beat’ competition, a press release said on Wednesday.

Under the patronage of the Ministries of Education and Public Health and with the support of Roche Lebanon and SGBL, the program targeted high school students to increase education and awareness on cancer.

U.S. senators on Tuesday introduced the most comprehensive legislation on medical marijuana ever brought before Congress, a bipartisan effort aimed at ending federal restrictions on the increasingly accepted treatment.

Twenty-three states already allow the use of cannabis to treat medical conditions like multiple sclerosis (MS) and epilepsy, but federal law still exposes users of the drug to potential investigation and arrest.

The sugar industry convinced U.S. government scientists decades ago to research ways of preventing cavities that did not involve eliminating sweets from the diet, a study said Tuesday.

The findings in the journal PLOS Medicine were based on 319 industry documents from the 1960s and 1970s that were stored in a public library collection at the University of Illinois.

U.S. fast-food chain Burger King said Tuesday it was cutting soft drinks from its children's meals amid mounting pressure to reduce the amount of sweet sodas that kids drink.

Following in the footsteps of rival McDonald's, Burger King said all its childrens' meals would come with either apple juice, fat-free milk or low-fat chocolate milk.

New Zealand has received an "eco-terrorist" threat to poison baby formula, Prime Minister John Key said Tuesday, in a scare that risks further denting the country's "clean, green" reputation.

Police said they were taking the issue seriously after small packages of baby formula containing poison were sent with anonymous letters to the National Farmers Federation and dairy giant Fonterra.

Unhealthy eating, smoking and obesity are threatening a heart disease epidemic in China, where three out of four people are in poor cardiovascular shape, said a study on Monday.

The findings published in the Journal of the American College of Cardiology are based on data from 96,000 men and women in the general Chinese population.

Real-time imaging in lab monkeys has pointed to the havens where HIV lurks after being beaten back by drugs, scientists said on Monday.

The achievement may provide a powerful weapon in the quest for an AIDS cure, they hope.

China has banned the harvesting of transplant organs from executed prisoners, a senior official said, but international medical practitioners warn that inmates' body parts may simply be reclassified as "donations" instead.

High demand for organs in China and a chronic shortage of donations mean that death row inmates have been a key source for years, generating heated controversy.
