New era of fisheries policy needed to secure nutrition for millions
|
|
|
A new study argues that for fisheries policies to be effective they must take in to account not just fish stock conservation and environmental issues, but also research data on the patterns and dynamics of fish trade, markets and user consumption.

Physicist's tool has potential for brain mapping
|
|
|
Physicists are developing a new tool that uses low-energy near-infrared light and fiber optics for optogenetic stimulation of cells. He believes it will be a useful tool for mapping physical and functional connections in the brain.

Asian lady beetles use biological weapons against their European relatives
|
|
|
Once introduced for biological pest control, Asian lady beetle populations have been increasing uncontrollably. Scientists have now found the reason for the animal's success. Its body fluid contains microsporidia, fungus-like protozoa that parasitize body cells and can cause immense harm to their host. The Asian lady beetle is obviously resistant to these parasites. However, transferred to native species, microsporidia can be lethal.

Scientific insurgents say 'Journal Impact Factors' distort science
|
|
|
An ad hoc coalition of unlikely insurgents -- scientists, journal editors and publishers, scholarly societies, and research funders across many scientific disciplines -- today posted an international declaration calling on the world scientific community to eliminate the role of the journal impact factor in evaluating research for funding, hiring, promotion, or institutional effectiveness.

X-ray tomography of living frog embryo
|
|
|
Classical X-ray radiographs provide information about internal, absorptive structures of organisms such as bones. Alternatively, X-rays can also image soft tissues throughout early embryonic development of vertebrates. Related to this, a new X-ray method allowed researchers to view three dimensional reconstructions showing developing embryos of the African clawed frog.

Developmental genetics of space and time
|
|
|
Scientists have conducted a study that reveals important and useful insights into how and why developmental genes often take inputs from two independent “morphogen concentration gradients.”

No idle chatter: Malaria parasites 'talk' to each other
|
|
|
Scientists have made the surprise discovery that malaria parasites can 'talk' to each other -- a social behavior to ensure the parasite's survival and improve its chances of being transmitted to other humans. The finding could provide a niche for developing antimalarial drugs and vaccines that prevent or treat the disease by cutting these communication networks.
