Who am I? How cells find their identity
A research group has investigated more closely how a single embryonic cell develops into a heart, nerve or blood cell. For the first time, the researchers have been able to reconstruct the developmental trajectories of individual embryonic cells. Their results also suggest that cells can change their path during their maturation process.

Genetic roadmap to building an entire organism from a single cell
In three landmark studies,researchers report how they have systematically profiled every cell in developing zebrafish and frog embryos to establish a roadmap revealing how one cell builds an entire organism. The findings represent a catalog of genetic 'recipes' for generating different cell types and provide an unprecedented resource for the study of developmental biology and disease.

Protect forest elephants to conserve ecosystems, not DNA
New research has found that forest elephant populations across Central Africa are genetically quite similar to one another. Conserving this critically endangered species across its range is crucial to preserving local plant diversity in Central and West African Afrotropical forests -- meaning conservationists could save many species by protecting one.

We still don't know how strange celibate animals evolve
A new study has cast doubt on leading theory for how tiny creatures have evolved for 50 million years -- without ever having sex.

Killer whale genetics raise inbreeding questions
A new genetic analysis of Southern Resident killer whales found that two male whales fathered more than half of the calves born since 1990 that scientists have samples from, a sign of inbreeding in the small killer whale population that frequents Washington's Salish Sea and Puget Sound.

Engineered Chinese shrub produces high levels of antimalarial compound
Artemisinin is a potent antimalarial compound produced naturally in low amounts by the Chinese shrub Artemisia annua, commonly known as sweet wormwood. Researchers in China now report a high-quality draft genome sequence of A. annua and their use of this information along with gene expression data to metabolically engineer plant lines that produce high levels of artemisinin.

What can a tasty milkshake teach us about the genetics of heart disease?
Analysis of high-resolution genomic data in a large study population reveals novel low-frequency polymorphisms that drive response to dietary lipids and medication.

A non-coding RNA lasso catches proteins in breast cancer cells
A Danish-German research team has shown that not only the where and when of long non-coding RNA expression is important for their function but also the how. The results can have a big impact on our understanding of dynamic regulation of gene expression in biological processes.

Natural barcodes enable better cell tracking
Researchers have developed a new genetic analysis technique that harnesses the 10 million small nucleotide polymorphisms (SNPs) found in the human genome as 'barcodes' to create a faster, cheaper, and simpler way to keep track of pooled cells from multiple individuals during multiplexed experiments, enabling large samples of cells from multiple people to be quickly analyzed for personalized medicine.

New take on early evolution of photosynthesis
Scientists have begun re-thinking the evolutionary history of photochemical reaction centers (RCs). Their analysis describes a new pathway that ancient organisms may have taken to evolve the great variety of photosynthetic RCs seen today across bacteria, algae, and plants.
