X-ray imaging of a single virus in 3-D

By imaging single viruses injected into the intense beam of an X-ray free-electron laser, researchers have determined the three-dimensional structure of the mimivirus. The technique could be applied to image other pathogenic viruses like HIV or influenza and, with further improvements, it may allow researchers to tackle smaller biomolecules like proteins. This could enable the study of many important biomolecules that cannot form crystals and thus cannot be investigated by X-ray crystallography. —> Read More Here

Infant gut bacteria and food sensitization: Associations in the first year of life

New light has been shed on changes in intestinal bacteria of infants that can predict future development of food allergies or asthma. The research reveals that infants with a fewer number of different bacteria in their gut at three months of age are more likely to become sensitized to foods such as milk, egg or peanut by the time they are one year old. —> Read More Here

Discovery of 2.8 million year old jaw sheds light on early Homo

For decades, scientists have been searching for African fossils documenting the earliest phases of the Homo lineage, but specimens recovered from the critical time interval between 3 and 2.5 million years ago have been frustratingly few and often poorly preserved. However, a fossil lower jaw found in the Ledi-Geraru research area, Afar Regional State, Ethiopia, pushes back evidence for the human genus — Homo — to 2.8 million years ago. —> Read More Here
