Mohamed Ibrahim fled to Ethiopia to seek relief from a harsh drought devastating his country Somalia, but misery stalked him in refuge where malnutrition recently killed his one-year-old son.

The desperate exodus by tens of thousands of Somalis to find assistance across borders has taken them to refugee settlements, where spartan living conditions, congestion and threat of disease are making survival difficult.

World Health Organization officials said Friday that famine-hit Somalia faces a cholera epidemic as dirty water and poor sanitation are leading to an increase in outbreaks of the disease.

Officials say cases of acute watery diarrhea — an important indicator of the risk of cholera — are now at 4,272 in Somalia — an 11 percent rise on last week's WHO reported figure of 3,839.

They savor pizza and burgers, no longer frighten children, and many of them can walk the streets without people knowing they have someone else's cheeks, nose, lips and skin. People who have had face transplants increasingly are going public, helping to transform an operation that six years ago was daredevil theory into one that is widely accepted.

At least 18 face transplants have been done around the world, starting with a French woman mauled by her dog in November 2005, said Dr. Maria Siemionow, at Cleveland Clinic. She did the first face transplant in the U.S. in December 2008.

Tests that measure DNA in a pregnant woman's blood work well for telling the sex of a baby after seven weeks' gestation without posing danger to the fetus, a U.S. study said Tuesday.

The meta-analysis of previous studies on the topic suggests that using cell-free fetal DNA from the mother's blood is more accurate than a urine test or sonogram and is safer than amniocentesis.

Malaria is spread to humans by female mosquitoes who suck blood in order to help their offspring grow, but British scientists said Monday that introducing spermless males could halt the deadly disease.

Scientists at Imperial College London said that by genetically tweaking male mosquitoes to produce no sperm, females would still mate with them but would lay unfertilized eggs that would not hatch into mosquito larvae.

Long working hours can more than triple the risk of alcohol abuse and addiction, New Zealand research has found.

An Otago University study of more than 1,000 people aged 25-30 found a statistically significant link between the amount of hours worked and alcohol abuse.

She waited 1 1/2 hours at the hospital, only to see a nurse who yelled that she was "lying about being in labor." Three hours later, her baby was born dead.

Another woman gave birth on the street, steps away from a clinic that twice turned her away, saying her time had not come.

Six years after leprosy was declared officially eliminated in India, officials and doctors are warning that the disfiguring disease is spreading in poverty-stricken pockets of the country.
