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.

Drinking kefir may prompt brain-gut communication to lower blood pressure
Drinking kefir may have a positive effect on blood pressure by promoting communication between the gut and brain. Kefir is a fermented probiotic milk beverage known to help maintain the balance of beneficial bacteria in the digestive system.

Redefining the origin of the cellular powerhouse
Researchers proposes a new evolutionary origin for mitochondria -- also known as the 'powerhouses of the cell.' Mitochondria are energy-converting organelles that have played key roles in the emergence of complex cellular life on Earth.

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.

3-D printed food could change how we eat
Researchers consider how 3-D printing technology could be used for food production.

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.

Dark chocolate consumption reduces stress and inflammation
Findings from two new studies show dark chocolate consumption reduces stress and inflammation, while improving memory, immunity and mood.

Deep water aquifer acts like natural bio-reactor, allowing microbes to consume carbon
Researchers have shown that underground aquifers along the mid-ocean ridge act like natural biological reactors, pulling in cold, oxygenated seawater, and allowing microbes to break down more -- perhaps much more -- refractory carbon than scientists ever believed.
