Vaccinate Mosquitoes Instead of Humans
Scientists researching mosquito-borne diseases like dengue fever have recently succeeded at "vaccinating" one generation of mosquito which then passes immunity onto its progeny.
What's the Big Idea?
Vaccinating humans against disease has proven the most effective method at stopping the spread of contagions, but what about diseases for which there are no vaccines, particularly those animal-borne like malaria, West Nile Virus and dengue fever? Can we coax nature into helping us eradicate disease that neither aids in the survival of animals or humans? Is it worth genetically modifying nature so that it suits us, rather than us accommodating its often harsh realities?
What's the Most Recent Development?
Two groups of scientists have recently achieved successes against mosquito-borne diseases like dengue fever. The Australian scientist Scott O'Neill has found that by injecting mosquitoes with a harmless bacterium, they become resist to and unable to transmit dengue fever. What's more, they pass on their immunity to future mosquito generations. And last December, a British biotechnology company engineered infertile male mosquitoes, releasing them into the wild on the Grand Cayman Islands and reducing the mosquito population by eighty percent.
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.
