Drug-Resistant Malaria Gaining Ground
A drug-resistant strain of malaria first noticed in Cambodia in 2005 is increasingly seen in other parts of Asia. Experts worry it could spread to Africa, where a majority of malaria exists.
What's the Latest Development?
A drug-resistant strain of malaria first noticed by scientists in Cambodia in 2005 has made its way to border of Thailand, suggesting the disease will continue to spread. The strain has achieved a certain immunity against the most effective anti-malaria treatment known as sweet wormwood, a derivative of the Chinese plant Artemisia annua. "Over the nine years between 2001 and 2010, [researchers at the Shoklo Malaria Research Unit] found that drugs became less effective and the number of patients showing resistance rose to 20%."
What's the Big Idea?
Researchers are especially worried that the resistant parasite might spread to sub-Saharan Africa, where a majority of the world's malaria cases exist. It remains unclear whether mosquitoes have carried the disease into Thailand or if the drug-resistant strain emerged spontaneously. "Either the resistance has moved and it will continue to move and will eventually reach Africa. Or if it has emerged, now that artemisinin is the standard therapy worldwide then it means it could emerge anywhere," said Professor Francois Nosten, who has worked on the latest research.

Both schizophrenics and people with a common personality type share similar brain patterns.
- A new study shows that people with a common personality type share brain activity with patients diagnosed with schizophrenia.
- The study gives insight into how the brain activity associated with mental illnesses relates to brain activity in healthy individuals.
- This finding not only improves our understanding of how the brain works but may one day be applied to treatments.
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
