Two Experiments Show Fourth Spatial Dimension Effect

To the best of our knowledge, we humans can only experience this world in three spatial dimensions (plus one time dimension): up and down, left and right, and forward and backward. But in two physics labs, scientists have found a way to represent a fourth spatial dimension.

Leaving flatland – quantum Hall physics in 4-D

In literature, the potential existence of extra dimensions was discussed in Edwin Abbott’s satirical novel “Flatland: A Romance of Many Dimensions” (1884), portraying the Victorian society in 19th century England as a hierarchical two-dimensional world, incapable of realizing its narrow-mindedness due to its lower-dimensional nature.

Two-part system turns stem cells into whatever you want

Whether using embryonic or adult stem cells, coercing these master cells to convert to the desired target cell and reproduce flawlessly is difficult. Now an international team of researchers has a two-part system that can convert the cells to the targets and then remove the remnants of that conversion, leaving only the desired DNA behind to duplicate.

Self-calibration enhances BrainGate brain computer interface ease, reliability

A new study in Science Translational Medicine describes three software innovations that substantially improved the user experience and performance of the BrainGate brain computer interface (BCI). Researchers said the gains are a significant advance in their ongoing work to develop and test a practical BCI assistive technology that people with paralysis could use easily, reliably, independently, and on demand to regain control over external devices.

The innate immune system modulates the severity of multiple sclerosis

Multiple sclerosis, a debilitating neurological disease, is triggered by self-reactive T cells that successfully infiltrate the brain and spinal cord where they launch an aggressive autoimmune attack against myelin, the fatty substance that surrounds and insulates nerve fibers. Over time, the resulting bouts of inflammation permanently damage the myelin sheath and the nerve fibers it protects, disrupting nerve signals traveling to and from the brain.

Edge.org contributors discuss the future of AI – Machine Intelligence Research Institute

In January, nearly 200 public intellectuals submitted essays in response to the 2015 Edge.org question, “What Do You Think About Machines That Think?” (available online). The essay prompt began: In recent years, the 1980s-era philosophical discussions about artificial intelligence (AI)-whether computers can “really” think, refer, be conscious, and so on-have led to new conversations about… Read more »
