Larry Hester, 66, has been blind for half his life from a condition called retinitis pigmentosa. In September, 2014, an electronic stimulator was surgically implanted in his left eye. On October 1st, 2014 Duke eye surgeon Dr. Paul Hahn turned it on for the first time. While the device does not restore vision in the normal sense, it provides light-and-darkness differentiation.

Our genetic information is stored in DNA, tiny strands of nucleic acid that contain instructions for the functioning of our bodies. To express this genetic data, our DNA is copied into RNA molecules, which then translate the instructions into proteins that perform tasks in our cells. In addition to known RNAs, circRNA molecules are abundant, yet little has been known about how they are produced, and next to nothing has been known about the role they play in disease. Now, researchers have discovered how circRNAs are produced.

Researchers have strived to determine how neurons are produced and integrated into the brain throughout adult life. In an intriguing twist, scientists provide evidence that adult-born neurons are derived from a special type of circulating blood cell produced by the immune system. The findings -- which were made in crayfish -- suggest that the immune system may contribute to the development of the unknown role of certain brain diseases in the development of brain and other tissues.

Scientists reveal crucial steps and surprising structures in the genesis of the enzyme that divides the DNA double helix during cell replication. The research combined electron microscopy, perfectly distilled proteins, and a method of chemical freezing to isolate specific moments at the start of replication.

A new system to monitor the effects of nucleosome depletion in Xenopus egg extracts reveals that nucleosomes are required for spindle assembly and for recruitment of nuclear pore complex (NPC) components to the nuclear envelope for NPC formation.
BigField GEG Tech's insight:
Proteins known as histones give structure to DNA, which coils around them like string on spools. But as is so often the case in biology, it turns out there is more to these structures than meets the eye.

Scientists have created an artificial, network-like cell system that is capable of reproducing the dynamic behavior of protein synthesis. This achievement is not only likely to help gain a deeper understanding of basic biological processes, but it may, in the future, pave the way toward controlling the synthesis of both naturally-occurring and synthetic proteins for a host of uses.

Investigators have successfully transplanted hearts from genetically engineered piglets into baboons' abdomens and had the hearts survive for more than one year, twice as long as previously reported. This was achieved by using genetically engineered porcine donors and a more focused immunosuppression regimen in the baboon recipients, according to a new study.

A new drug, OTS964, can eradicate aggressive human lung cancers transplanted into mice, scientists report. It inhibits the action of a protein that is overproduced by several tumor types but is rarely expressed in healthy adult tissues. Without it, cancer cells fail to complete the cell-division process and die.
