ANN ARBOR-With the help of light-emitting diodes as small as neurons, University of Michigan researchers are unlocking the secrets of neural pathways in the brain. The researchers have built and tested in mice neural probes that hold what are believed to be the smallest implantable LEDs ever made. The new probes can control and record the activity of many individual neurons, measuring how changes in the activity of a single neuron can affect its neighbors.

Cambridge, Mass., Dec. 9, 2015/PRNewswire/ — Flagship Ventures, a leading innovation and venture firm focused on healthcare and sustainability, announced it has launched Rubius Therapeutics, to develop functionalized red blood cells for the treatment of autoimmune conditions, metabolic diseases, cancer, and other serious diseases. Flagship has made an initial capital commitment of $25 million to enable Rubius to enter clinical testing of its novel therapeutic modality.

A study of a million UK women, published today in The Lancet, has shown that happiness itself has no direct effect on mortality, and that the widespread but mistaken belief that unhappiness and stress directly cause ill health came from studies that had simply confused cause and effect.

Researchers at the University of Warwick have worked with Coventry-based Medherant, a Warwick spinout company, to produce and patent the World’s first ever ibuprofen patch delivering the drug directly through skin to exactly where it is needed at a consistent dose rate.

Now a simple blood test can reveal your biological age—how old your body really is. The new research from Uppsala University is published in the journal Scientific Report@Nature today.

A pair of socks embedded with miniaturised microbial fuel cells (MFCs) and fuelled with urine pumped by the wearer’s footsteps has powered a wireless transmitter to send a signal to a PC. This is the first self-sufficient system powered by a wearable energy generator based on microbial fuel cell technology.

Today, the U. S. Food and Drug Administration cleared the use of the XSTAT 30 wound dressing, an expandable, multi-sponge dressing used to control severe, life-threatening bleeding from wounds in areas that a tourniquet cannot be placed (such as the groin or armpit) in battlefield and civilian trauma settings. The clearance expands the device’s indication from use by the military only to use in adults and adolescents in the general population.

Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain. Death and dysfunction of these cells cause vision loss in conditions like glaucoma and multiple sclerosis.
