Children just hate all vegetables, no matter how tasty you make them, right?

Wrong, says an influential study out Monday that found U.S. children in Massachusetts ate up to 30 percent more vegetables when school dinners were made more palatable with the help of a professional chef.

Giant rats may strike fear and disgust into the hearts of homeowners worldwide, but researchers in impoverished Mozambique are improbably turning some of them into heroes.

At Eduardo Mondlane University in the capital Maputo, nine giant rats are busy at work -- sniffing out tuberculosis-causing bacteria from rows of sputum samples.

Oncologist Gabriel Romero performs hundreds of life-saving surgeries a year, but he no longer takes pleasure in his work.

That's because he believes that many of the mastectomies he does on some of Venezuela's poorest women wouldn't be needed in a normally functioning country. Doctors say they are being forced to return to outdated treatments because the socialist country's economic problems make it impossible to ensure the proper running of radiation machines in public hospitals, where patients receive free treatment under Venezuela's universal health care.

India is failing to tackle a tuberculosis epidemic because of chronic shortages of funds and the government's inability to regulate an "exploitive" private health sector, an article in the British Medical Journal said.

The article, published ahead of World Tuberculosis Day on Tuesday, called for a massive investment in public health infrastructure to diagnose and treat what it called India's biggest health crisis.

Aid agency Doctors Without Borders marked the first anniversary of Africa's Ebola outbreak Monday with a report slamming the international community's slow response and detailing the "indescribable horror" faced by its staff.

More than 10,000 people have been killed and nearly 25,000 infected since the Ebola epidemic was first identified in west Africa in March 2014, mostly in Guinea, Liberia and Sierra Leone.

The people of Monrovia's Peace Island ghetto, refugees of civil war who found themselves suddenly overwhelmed and outmanoeuvred by the deadly Ebola epidemic, are used to life under siege.

Yet with Liberia emerging from the worst outbreak in history a year to the day since Ebola was first identified in west Africa, the slum-dwellers are facing an even deadlier threat -- the measles virus. 

The U.N.'s International Agency for Research on Cancer (IARC) said Friday that three pesticides, including the popular weedkiller Roundup, were "probably" carcinogenic and two others, which have already been outlawed or restricted, were "possibly" so.

IARC classified the herbicide glyphosate -- the active ingredient in Roundup -- and the insecticides malathion and diazinon as "probably carcinogenic" on the basis of "limited evidence" of cancer among humans.

Health experts at an anti-tobacco conference in Abu Dhabi defended e-cigarettes on Friday, dismissing widespread concerns that the devices could lure adolescents into nicotine addiction.

Most experts agreed, however, that use of the devices, about which research warns that not enough is yet known, should be regulated.

The chanting begins quietly but quickly swells, the sound echoing depths of suffering that the music might heal. "Help me, each day is difficult, help me overcome this suffering."

The teenage girls singing in a state-of-the-art music studio near the Panzi hospital outside the city of Bukavu are young enough to be in school, but some are already mothers after being raped in the atrocities sweeping eastern parts of the Democratic Republic of Congo.

Liberia Friday confirmed its first new Ebola case in more than a month in a setback to hopes the country would soon be officially declared free of the deadly disease.

The country was the hardest hit at the peak of the epidemic in west Africa and has seen more than 4,000 deaths in all, but was at an advanced stage in its recovery and was expecting to be declared Ebola-free by mid-April before the latest case in the capital Monrovia.
