Researchers have developed two compounds that can kill malaria-causing parasites within mosquitoes, an approach they hope could help reduce transmission of the disease. The team showed that these compounds can be embedded into the plastics used to make bed nets, providing an alternative to insecticide-based malaria-control measures, which are losing efficacy in the face of increased resistance.

Researchers have found specific genetic mutations that can lead to pregnancy loss. It’s known that errors, such as the duplication of chromosomes, can lead to nonviable pregnancies but less has been known about non-chromosomal genetic errors. The new work identifies DNA sequence changes that can lead to a non-viable pregnancy. This may offer clinicians the ability to screen embryos for these changes to help avoid pregnancy loss.
