| A team of US researchers have determined the life cycle of operons, which are small group of genes with related function co-transcribed on a single strand of messenger RNA, a breakthrough which holds major significance to bateriologists and the advancement of synthetic biology. The operons play crucial roles in gene expression programs allowing bacteria to adapt to stresses in the environment. Up till now, despite being widespread among the genomes of all prokaryotes, the major reason as well as the consequences behind its diversity is not known.

| Genetically-modified wheat and barley are slated to boost nutrition by allowing an important nutritional enzyme to retain its structural conformation after cooking. The enzyme phytase aids in the absorption of zinc and iron, and the plants may be seen as a potential method in alleviating dietary mineral deficiency. In wheat, the enzyme may lose it shape and effectiveness at 63°C, while the modified enzyme may withstand temperatures of up to 89°C.

A gene has been identified as being the culprit behind the West African susceptibility to tuberculosis which may have strong bearing towards medical diagnostics. It has been noted that of the 27 variations found in the SP110 gene, three versions were associated with TB symptoms. This may be used to explain the low symptom induction rate of the disease. Currently, a third of the world’s population is infected by the disease, but only 10% of those infected show symptoms.
