Running won’t make you slim down, study says

Marathon training has little or no effect on most people’s weight, scientists say.

Many long-distance runners find that even when they are running more than 50 kilometres in a week their waistlines barely get smaller, with some actually gaining weight.

According to Harvard University’s lifestyle and nutrition researcher, Mary Kennedy, it is a particular problem for women. The university carried out a small study involving 64 people training for charity events.

After three months of running four days each week, 75 per cent neither lost or gained any significant amount of weight. They were, however, balanced out by one runner who put on several kilos. Out of the seven runners who gained weight, six of them were women. It is possible that the runners were burning fat and gaining muscle weight, but Kennedy insists it is down to diet and appetite.

Mary believes many people are not burning the extra calories that they are eating when training.


Drug-resistant malaria can infect mosquitoes

A drug-resistant malaria parasite found in South East Asia can also infect mosquito species in Africa, a study shows. The transmission experiments were carried out in a laboratory, but they suggest the spread of this deadly strain into the continent is possible. The scientists say the consequences of this would be dire, putting millions of lives at risk. The study is published in the journal Nature Communications. Dr Rick Fairhurst, from the National Institute of Allergy and Infectious Disease, in the US, who carried out the research, said

this would render the best front-line drug - Artemisinin - useless. This drug-resistant parasite was first seen in Cambodia in 2008, but has since been reported across South East Asia.


Half of Laikipia camels have Mers virus – study

ABOUT 47 per cent of camels in Laikipia county have been infected by the deadly Middle East Respiratory Syndrome virus, a study states.

The study was published on Saturday in the US journal Plos One by scientists from the University of Liverpool and institutions in the US, Kenya and Europe.

The journal covers primary research in science and medicine.

The study indicates 335 dromedary, single-humped camels from nine herds in the county tested positive for Mers antibodies, showing they had been exposed to the virus.

Although there have been no human Mers cases diagnosed in Kenya, the researchers said there is a risk these camels can spread the disease to humans.


Google invests in Lake Turkana power project

Google has announced its commitment to invest up to Sh4 billion in Lake Turkana Wind Power Project. Once operational, the Lake Turkana Wind Power Project will bring 310 megawatts of clean energy onto Kenya’s grid—enough to power more than two million households across the country. Lake Turkana will help bring much needed capacity and stability to Kenya’s energy supply, reducing reliance on fossil fuels and emergency diesel generation while providing some of the most cost effective power in the country.

Google will join a diverse group of international investors in the project, including the Overseas Private Investment Corporation, the US government’s development finance institution, and Vestas, which is also supplying the turbines for the wind farm. Google will purchase Vestas’ 12.5% stake in Lake Turkana once it comes online.
