Targeting sperm protection in mosquitoes could help combat malaria

Posted: 07 Apr 2014 12:51 PM PDT

Researchers have discovered a way of reducing the fertility of malaria-carrying mosquitoes, potentially providing a new tactic to combat the disease.

Anopheles gambiae mosquitoes are the main transmitters of malaria, which affects around 200 million people every year. The females mate only once during their lives. They store the sperm from this single mating in an organ called the spermatheca, from which they repeatedly take sperm over the course of their lifetime to fertilise the eggs that they lay..

Imagine the anguish of a parent whose child is diagnosed with an incurable form of childhood brain cancer. Surgery is not an option, current chemotherapy is ineffective and focal radiation only provides temporary relief.

Remarkably, researchers from the University of Toronto’s Department of Laboratory Medicine and Pathobiology (LMP) have defined potential treatment targets for this relatively common cancer – providing hope for future patients.

Organic Solar Cells More Efficient With Molecules Face-to-Face

New research from North Carolina State University and UNC-Chapel Hill reveals that energy is transferred more efficiently inside of complex, three-dimensional organic solar cells when the donor molecules align face-on, rather than edge-on, relative to the acceptor. This finding may aid in the design and manufacture of more efficient and economically viable organic solar cell technology.
