Genome sequence of polar alga explains evolutionary adaptation to extreme variable climate
An international team of researchers has identified the genetic mutations which allowed microalgae (phytoplankton) from the Southern Ocean to adapt to extreme and highly variable climates -- a step towards understanding how polar organisms are impacted by climate change.

New study refutes how fruit flies developed their tolerance for alcohol
Scientists have conducted experiments investigating whether a molecular change in an enzyme gave the Drosophila melanogaster fruit fly species its superior ability to metabolize alcohol.

How to be winner in the game of evolution
A new study helps explain why different groups of animals differ dramatically in their number of species, and how this is related to differences in their body forms and ways of life.

Pig gene advance could boost sperm stocks from prized animals
Gene-editing techniques could help to improve stocks of farmed pigs by boosting supplies of sperm from prized sires. Scientists have created male pigs that could be used as surrogates capable of producing sperm that contains the genetic blueprint of sought-after pigs. Researchers say the breakthrough will allow farmers to preserve sperm from prized animals in perpetuity.

Scientists engineer animals with ancient genes to test causes of evolution
Scientists have created the first genetically modified animals containing reconstructed ancient genes, which they used to test the evolutionary effects of genetic changes that happened in the deep past on the animals’ biology and fitness.

Chemist develops new theory for explaining the function of proteins
A chemist and a collaborator have developed a new theory for explaining how proteins and other biomolecules function based on movement and change of shape and structure rather than content.

Diagnostic breakthrough: 'Shaking piglets' attributed to previously unidentified virus
Symptoms of tremors and shaking in newborn piglets are not a sign that the animals are cold, but rather that they are suffering from a specific viral infection. Researchers have now been able to prove this correlation for the first time using a newly developed test. The scientists detected a previously unknown virus, termed atypical porcine pestivirus (APPV), in “shaking piglets”, making it possible to clearly diagnose the potentially fatal disease.
