Song-learning neurons identified in songbirds
A group of neurons called the corticobasal ganglia projecting neurons are important for vocal learning in young birds, but not in adult birds, according to a new study.

Widespread drying of European peatlands in recent centuries
Researchers examined 31 peatlands across Britain, Ireland, Scandinavia and continental Europe to assess changes in peatland surface wetness during the last 2,000 years.

Using high-throughput next-generation sequencing technology, a researcher found similarities in the folding tendencies among a family of RNA molecules called riboswitches, which play a pivotal role in gene expression.

Scientists demonstrate a new approach in fluorescence microscopy that can be used to locate individual biomolecules in 3D space with nanometer-scale precision.
Read moreDefining the centromere
Centromeres are the chromosomal domains at which the kinetochore, a protein complex required for the correct separation of chromosomes during mitosis and meiosis, is assembled. The incorporation of the histone variant CenH3 into centromeric nucleosomes is a prerequisite for the proper assembly and function of the kinetochore. A new study describes the chaperone protein NASPSIM3 and how it affects the depositioning of CenH3.

There are many indications that fasting promotes longevity. In recent years, much attention has been devoted to so-called caloric restriction mimetics (CMRs), substances that simulate the health-promoting effects of fasting without the need of life-style change. A study reports the identification of a novel candidate CRM. The substance may prove useful in the further research for the treatment of age-related diseases.

Bacterial cell division is controlled by both enzymatic activity and mechanical forces, which work together to control its timing and location.
Bioprinting: Living cells in a 3D printer
A high-resolution bioprinting process has been developed: Cells can now be embedded in a 3D matrix printed with micrometer precision — at a printing speed of one meter per second, orders of magnitude faster than previously possible. Tissue growth and the behavior of cells can be controlled and investigated particularly well by embedding the cells in a delicate 3D framework. This is achieved using so called 'bioprinting' techniques.

The world's weirdest little primate has gotten even weirder, thanks to the discovery of a tiny extra digit. Aye-ayes possess small 'pseudothumbs' — complete with their own fingerprints — that may help them grip objects and branches as they move through trees. This is the first accessory digit ever found in a primate.
Real texture for lab-grown meat
Researchers have grown rabbit and cow muscles cells on edible gelatin scaffolds that mimic the texture and consistency of meat, demonstrating that realistic meat products may eventually be produced without the need to raise and slaughter animals.
