The world's most advanced malaria candidate vaccine offers young children partial protection that wanes with time, but could shield millions against the deadly parasite, its developers said Friday.

Researchers published the final results of a years-long trial with the drug RTS,S in The Lancet medical journal.

The collapse of health services in three west African countries devastated by Ebola may have caused some 11,000 additional deaths from malaria, a preventable and curable disease, researchers said Friday.

A further 3,900 deaths may have resulted from interruptions in the delivery of insecticide-treated bed nets, according to outbreak modelling data published in The Lancet on the eve of World Malaria Day.

Malaria still claims nearly 600,000 lives a year, the U.N. said Thursday, urging further action to boost recent strides in combatting the disease.

A growing resistance to a frontline malaria drug is compounding the other shortcomings in prevention, diagnosis and treatment, the World Health Organization said.

An Australian blogger who found fame after claiming she was conquering brain cancer through natural therapy, her app even getting chosen for the new Apple watch, admitted Thursday she never had the disease.

Belle Gibson launched her successful The Whole Pantry business in 2013 -- billed as the world's first health, wellness and lifestyle app community -- on the back of healing herself naturally through wholefoods and alternative therapies.

Deep in Liberia's forested hinterland, thousands of refugees who fled conflict in Ivory Coast have been waiting in limbo, impatient to rebuild their shattered lives back home but unable to leave.

They were preparing their return last summer when suddenly they found themselves trapped in a major tropical disease outbreak as Ebola ravaged their host nation, prompting the government to close its borders.

Poultry producers and scientists have been hoping warmer weather would knock down a virulent strain of bird flu that has hammered the U.S. Midwest, but the virus recently took its biggest toll yet, hitting a farm in Iowa that held nearly 10 percent of the state's egg-laying chickens. Here are some questions and answers about the outbreak:

WHAT'S THE LATEST?

U.S. regulators assessing homeopathic treatments' safety and efficacy could overhaul rules of the multi-billion-dollar industry, they said Tuesday.

Two days of public hearings wrapped up Tuesday to help determine if current regulations are still relevant for the industry that has seen "explosive growth" in the last 25 years, the Food and Drug Administration said in a statement.

Ethanol poisoning from a locally brewed gin may have been responsible for the sudden death of 18 people last week, Nigerian health authorities said Monday.

"We strongly suspect ethanol poisoning and in view of this, we have ordered for another toxicology test for the surviving victims," Ondo state health commissioner Dayo Adeyanju told Agence France Presse.

Women should get a mammogram every two years starting at age 50 — and while routine screening brings little benefit in the 40s, beginning it that early should be a personal choice, a government task force said Monday.

Also, there's not enough evidence to tell if new 3-D mammograms are the best option for routine screening, or if women with dense breasts need extra testing to find hidden tumors, the U.S. Preventive Services Task Force concluded.

A form of mental training which helps people recognise the onset of depression, and control it, works as well as anti-depressants in preventing relapse, researchers said Monday.

Dubbed Mindfulness-Based Cognitive Therapy (MBCT), the method may offer a welcome alternative for people wishing to avoid long-term use of anti-depressants, which can have unpleasant side effects like insomnia, constipation and sexual problems, said a study in The Lancet medical journal.
