- Scientists wipe out malaria-carrying mosquitoes in the lab with genetic method that creates male-only offspring
- Herpes Infected Humans Before They Were Human
- Brain scans differentiate adults who have recovered from childhood ADHD and those whose difficulties linger
| Posted: 10 Jun 2014 06:30 PM PDT Scientists have modified mosquitoes to produce sperm that will only create males, pioneering a fresh approach to eradicating malaria. In a study published in the journal Nature Communications, scientists from Imperial College London have tested a new genetic method that distorts the sex ratio of Anopheles gambiae mosquitoes, the main transmitters of the malaria parasite, so that the female mosquitoes that bite and pass the disease to humans are no longer produced. |
| Herpes Infected Humans Before They Were Human Posted: 10 Jun 2014 05:35 PM PDT Researchers at the University of California, San Diego School of Medicine have identified the evolutionary origins of human herpes simplex virus (HSV) -1 and -2, reporting that the former infected hominids before their evolutionary split from chimpanzees 6 million years ago while the latter jumped from ancient chimpanzees to ancestors of modern humans – Homo erectus – approximately 1.6 million years ago. The findings are published in the June 10 online issue of Molecular Biology and Evolution. |
| Posted: 10 Jun 2014 05:31 PM PDT About 11 percent of school-age children in the United States have been diagnosed with attention deficit hyperactivity disorder (ADHD). While many of these children eventually “outgrow” the disorder, some carry their difficulties into adulthood: About 10 million American adults are currently diagnosed with ADHD. |
