Scientists wipe out malaria-carrying mosquitoes in the lab by creating male-only offspring

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,…

  GEOMAR researchers show limitations and side effects of large-scale climate intervention 25 February 2014/Kiel. With global greenhouse gas emissions continuing to increase proposals to limit the effects of climate change through the large-scale manipulation of the Earth system are increasingly being discussed. Researchers at the GEOMAR Helmholtz Centre for Ocean Research Kiel have now…

The symphony of life, revealed

  A new imaging technique captures the vibrations of proteins, tiny motions critical to human life              IMAGE:   Using a new imaging technique they developed, scientists have managed to observe and document the vibrations of lysozyme, an antibacterial protein found in many animals. This graphic visualizes the vibrations… Click here for more information.…

Pesticide combination affects bees’ ability to learn

Contact: Rob Dawson Rob.Dawson@bbsrc.ac.uk 01-793-413-204 Biotechnology and Biological Sciences Research Council Two new studies have highlighted a negative impact on bees’ ability to learn following exposure to a combination of pesticides commonly used in agriculture. The researchers found that the pesticides, used in the research at levels shown to occur in the wild, could interfere…

Changes in the gut bacteria protect against stroke

Contact: Fredrik Bäckhed fredrik.backhed@wlab.gu.se 46-313-427-833 University of Gothenburg Researchers at the University of Gothenburg, Sweden, and the Chalmers University of Technology, Sweden, demonstrate that an altered gut microbiota in humans is associated with symptomatic atherosclerosis and stroke. These findings are presented in a study published in Nature Communications on December 4. The human body contains…
