Experiment Sets to Find Out if Our World is a Hologram

Abstract illustration of neurons interacting with path

Genuine questions about our world may finally be answered if all goes according to plan. Using a fairly complex device called the Holometer or "holographic interferometer," scientists split a laser in two and beam them through a perpendicular path until they reach mirrors which bounce back and recombine with the beam splitter. By analyzing fluctuations or waves in the beams, researchers hope to find "holographic noise" which could probe the very nature of space-time itself.

Laser Light Used To Change Memories In Mice

Text Description

Using a tiny burst of concentrated light, scientists have actually taken a big step towards understanding how cells in the brain record memories with the help of mice. Nature (The International Journal Of Science) published results in late August which reveal that negative memories aren't permanent and can often be rewritten each time it is recalled, similar to how witness testimony tends to change throughout multiple statements. Neuroscientist Richard Morris of the University of Edinburgh says the study provides a “much more precise handle on some of the steps of memory formation than we’ve had before.” Memories are encoded in groups of neurons which act together in specific patterns and certain regions of the brain are responsible for analyzing different elements of an event.

100 lbs of Magnetic Putty Really Makes You Think

The folks over at Vat19.com went above and beyond with this Q&A about their popular Magnetic Thinking Putty. Along with a variety of quirky experiments, this widely shared infomercial also includes a timelapse clip of the mystical putty interacting with high-powered magnets for a strange but satisfying take on this malleable matter.

Pyro Board: 2D Rubens' Tube Shows Why Humans Discovered Fire

With the art of pressure and sound from the latest musical genres, this quick clip demonstrates how waves truly move around us.  As the songs are projected into the Pyro Board, the sound waves control the intensity of the flames, the height, and even the color!  It's similar to a pyrotechnic show synchronized to music for an amazing visual experience as the waves produce some fairly intricate patterns.
