The behavioral disorders observed in autism are associated with a multitude of genetic alterations. Scientists have now found another molecular cause for this condition. The transcription factor MYT1L normally protects the molecular identity of nerve cells. If it is genetically switched off in human nerve cells or in mice, the functional changes and symptoms typical of autism occur. A drug that blocks sodium channels in the cell membrane can reverse the consequences of MYT1L failure and alleviate the functional and behavioral abnormalities in mice.

Scientists have created a new technology to assemble matter in 3D. Their concept uses multiple acoustic holograms to generate pressure fields with which solid particles, gel beads and even biological cells can be printed. These results pave the way for novel 3D cell culture techniques with applications in biomedical engineering.

Computer software can predict what happens to complex gene networks when individual genes are missing or dialed up more than usual. Mapping the roles of single genes in these networks is key to understanding healthy development and finding ways to regrow damaged cells and tissues. Understanding genetic errors could provide insight into birth defects, miscarriage or even cancer.

A new biomaterial that can be injected intravenously, reduces inflammation in tissue and promotes cell and tissue repair. The biomaterial was tested and proven effective in treating tissue damage caused by heart attacks in both rodent and large animal models. Researchers also provided proof of concept in a rodent model that the biomaterial could be beneficial to patients with traumatic brain injury and pulmonary arterial hypertension.

A new species of microalgae was found in water from a home aquarium. While analyzing DNA samples taken from the algae, researchers discovered Medakamo hakoo, whose DNA sequence didn't match any on record. This new species is the smallest known freshwater green algae, with inherent qualities which enable it to be cultured stably at high density, meaning it could be effectively used to produce useful products for food and industry.

In a new breakthrough, researchers have solved a problem that has caused quantum researchers headaches for years. The researchers can now control two quantum light sources rather than one. Trivial as it may seem to those uninitiated in quantum, this colossal breakthrough allows researchers to create a phenomenon known as quantum mechanical entanglement. This in turn, opens new doors for companies and others to exploit the technology commercially.
