The Tara Oceans expedition collected these small zooplanktonic animals in the Indian Ocean: a molluscan pteropod on the right, and 2 crustacean copepods. On the left is a fragment of...
In five related reports in this issue of the journal Science, a multinational team of researchers who spent three and a half years sampling the ocean's sunlit upper layers aboard the schooner Tara unveil the first officially reported global analyses of the Tara Oceans consortium. Planktonic life in the ocean is far more diverse than scientists knew, these reports show. They provide new resources for cataloguing the ocean's numerous planktonic organisms, which -- though critical to life on Earth, providing half the oxygen generated annually through photosynthesis, for example -- have largely been uncharacterized. The reports also reveal how planktonic life is distributed and how planktonic species interact, and they suggest that these organisms' interactions, more so than environmental conditions, help explain their community structures.

Phages infect bacteria and are able to transfer genes during this process.
Bacteria resistant to antibiotics are on the rise. There are different explanations for how resistances are transferred. Researchers from the Vetmeduni Vienna found phages in chicken meat that are able to transfer antimicrobial resistance to bacteria. Phages are viruses that exclusively infect bacteria. They can contribute to the spread of antimicrobial resistance. The findings may also be relevant for clinical settings. The study was published in the journal Applied and Environmental Microbiology.

Axons in red and neuronal cell bodies in green show cell bodies following the red axons
When nerve cells form in an embryo they do not start off in the right place but have to be guided to their final position by navigating a kind of molecular and cellular "map" in order to function properly. In a recent research study published in Nature Communications neurobiologist Sara Wilson, UmeƄ University, found that during embryonic development different parts of the nerve cell are important for guiding other nerve cells into their physical positions.

Using nature for inspiration, a team of Northwestern University scientists is the first to develop an entirely artificial molecular pump, in which molecules pump other molecules. This tiny machine is no small feat. The pump one day might be used to power other molecular machines, such as artificial muscles.

Antiretroviral therapy (ART) has proven lifesaving for people infected with HIV; however, the medications are a lifelong necessity for most HIV-infected individuals and present practical, logistical, economic and health-related challenges. A primary research goal is to find an HIV cure that either clears the virus from an infected person's body or enables HIV-infected individuals to suppress virus levels and replication to extremely low levels without the need for daily ART.

Cancer research leaders at the Ontario Institute for Cancer Research, Oregon Health & Science University, Sage Bionetworks, the distributed DREAM (Dialog for Reverse Engineering Assessment and Methods) community and The University of California Santa Cruz published the first findings of the ICGC-TCGA-DREAM Somatic Mutation Calling (SMC) Challenge (The Challenge: https://www.synapse.org/#!Synapse:syn312572) today in the journal Nature Methods. These results provide an important new benchmark for researchers, helping to define the most accurate methods for identifying somatic mutations in cancer genomes. The results could be the first step in creating a new global standard to determine how well cancer mutations are detected.
