Monkeys protect against lethal Ebola Sudan infection four days after infection
Researchers have protected nonhuman primates against Ebola Sudan four days following exposure to the virus.

New types of African Salmonella associated with lethal infection
The first global-scale genetic study of Salmonella Enteritidis bacteria, which is a major cause of blood poisoning and death in Africa and food poisoning in the Western World, has discovered that there are in fact three separate types. Scientists found two novel African types, which looked the same, but were genetically different from the Western type.

Transcription factor Foxn1 and preserving immune function in later life
Researchers use new experimental models and analytical tools to investigate genes regulated by Foxn1, becoming the first to identify the DNA sequence bound by the transcription factor. Among the hundreds of genes whose expression is regulated by Foxn1 are genes essential to attract precursor cells in the blood to the thymus, that commit precursor cells to become T cells, and that provide the molecular machinery which allows T cell selection to best serve an individual.

Single-celled fungi multiply, alien-like, by fusing cells in host
Biologists report that microsporidia fuse the cells of their animal hosts together so they can multiply and quickly spread, alien-like, within their hosts' uninfected cells.

New global migration mapping to help fight against infectious diseases
Geographers have completed a large scale data and mapping project to track the flow of internal human migration in low and middle income countries. Researchers have, for the first time, mapped estimated internal migration in countries across three continents; Africa, Asia and Latin America and the Caribbean.

Fungi recycle rechargeable lithium-ion batteries
Rechargeable batteries in smartphones, cars and tablets don't last forever. Old batteries often wind up in landfills or incinerators, potentially harming the environment. And valuable materials remain locked inside. Now, a team of researchers is turning to fungi to drive an environmentally friendly recycling process to extract cobalt and lithium from tons of waste batteries.

Proton pump found to regulate blood pH in stingrays
Researchers have discovered the same enzyme used by 'boneworms' to dissolve whale carcasses, and that helps promote photosynthesis in corals, also regulates blood pH in stingrays. The study could help scientists better understand the enzyme's function in human kidneys to regulate blood and urine functions.

Spider silk: Mother Nature's bio-superlens
Hot on the heels of a paper revealing that a team of researchers has used a nanobead-derived superlens to break the perceived resolution barrier, the same team has achieved another world first by using spider silk as a superlens to increase the microscope's potential.

Researchers innovate brain preservation technique
By figuring out how to preserve specimens in the remote locations in which they are found -- locations almost completely opposite those of a controlled laboratory or 21st century urban area -- researchers have given science one more way to study a wide range of creatures, particularly those threatened by global climate change.

'Missing evolutionary link' of a widely used natural drug source found
A well-known family of natural compounds, called “terpenoids,” have a curious evolutionary origin. In particular, one question relevant to future drug discovery has puzzled scientists: exactly how does Nature make these molecules?
