Pakistani tax authorities took the unusual step Friday of threatening retailers with heavy fines and prison unless they stop selling cigarettes smuggled from South Korea.

The Federal Board of Revenue ran an advertisement in newspapers, warning that PINE cigarettes were being sold on the market without duty, and lacked mandatory health and underage warnings.

Willpower apparently can be bought. The chance to win or lose $20 a month enticed dieters in a yearlong study to drop an average of 9 pounds (4 kilograms)— four times more weight than others who were not offered dough to pass up the doughnuts.

Many employers, insurers and Internet programs dangle dollars to try to change bad habits like smoking or not exercising, but most studies have found this doesn't work very well or for very long.

A fund of millions of dollars raised to help malnourished children in western India has been diverted to maintain public buses, a report said on Friday.

The "Child Nutrition Surcharge" was set up 16 years ago to collect a small percentage of each bus ticket fare in major cities in Maharashtra state, where thousands of children die from malnutrition each year.

The Health Ministry announced on Thursday that a truck smuggling medication from Turkey has been seized in the Bekaa.

It said that the Internal Security Forces had stopped the truck at a checkpoint near the Bekaa town of Zahleh where it discovered its load.

Aid agencies and governments must tackle the taboos surrounding menstruation as sidelining the issue undermines the quality of life of women and girls, chiefly in poor nations, a U.N. body said Wednesday.

A high-salt diet may be a risk factor for autoimmune diseases like multiple sclerosis (MS), according to three papers published in the journal Nature on Wednesday.

Scientists said Thursday they had, for the first time, helped women with severe anorexia through electrodes implanted into their brains.

At a small and peaceful clinic on the outskirts of Yangon, 20 volunteers tend to 300 HIV patients abandoned by a health care system allowed to crumble during decades of brutal military rule in Myanmar.

In a country whose rulers long prioritized military spending over the needs of their people, these men, women and children have found a refuge thanks to the work of a member of Aung San Suu Kyi's opposition party.

Want to know your chances of dying in the next 10 years? Here are some bad signs: getting winded walking several blocks, smoking, and having trouble pushing a chair across the room.

That's according to a "mortality index" developed by San Francisco researchers for people older than 50.

U.S. researchers on Tuesday published incredibly detailed images of the human brain as part of an international project aimed at uncovering how brain architecture influences personality.

The five-year "Human Connectome Project" or HCP -- being conducted at 10 research centers in the U.S. and Europe -- will use advanced brain imaging technology to collect vast amounts of data on healthy adults and make it freely available to researchers worldwide.
