Science Saved My Soul. Automatic Mechanical Self Replication (part 1) Scientist creates lifelike cells out of metal. Scientists trying to create artificial life generally work under the assumption that life must be carbon-based, but what if a living thing could be made from another element? One British researcher may have proven that theory, potentially rewriting the book of life. Lee Cronin of the University of Glasgow has created lifelike cells from metal — a feat few believed feasible. The discovery opens the door to the possibility that there may be life forms in the universe not based on carbon, reports New Scientist.
Even more remarkable, Cronin has hinted that the metal-based cells may be replicating themselves and evolving. "I am 100 percent positive that we can get evolution to work outside organic biology," he said. The high-functioning "cells" that Cronin has built are constructed from large polyoxometalates derived from a range of metal atoms, like tungsten. The metallic bubbles are certainly cell-like, but are they actually alive? The early results have been encouraging. The Best illusion ever ? Yes.

20 Incredible Optical Illusions. An optical illusion is always characterized by visually perceived images that, at least in common sense terms, are deceptive or misleading. Therefore, the information gathered by the eye is processed by the brain to give, on the face of it, a percept that does not tally with a physical measurement of the stimulus source. This is a list of twenty amazing illusions. 1. Blivet A blivet, also known as a poiuyt, is an undecipherable figure, an optical illusion and an impossible object. 2. The Bezold Effect is an optical illusion, named after a German professor of meteorology, Wilhelm von Bezold (1837-1907), who discovered that a color may appear different depending on its relation to adjacent colors. 3.
The café wall illusion is an optical illusion, first described by Doctor Richard Gregory. 4. The Chubb illusion is an optical illusion wherein the apparent contrast of an object varies dramatically, depending on the context of the presentation. 5. 6. 7. 8. 9. 10. 12. 13. 14. 15. 16. 17. 18. 19. Physics Is Beauty (Video) Using Tiny Glass Spheres as a Superlens, Microscope Shatters Resolution Record | 80beats. Modern microscopes opened up the world of the minute to an amazing degree, allowing people to see all the way down to a bacterium wriggling on a slide. But if you want to see down even smaller in regular optical light—to a virus, a cell’s interior, or other objects on the nanoscale—you’ve been out of luck. Those objects are smaller than 200 nanometers, what’s been considered the resolution limit for microscopes scanning in white light, and so the only was to see them was through indirect imaging devices like scanning electron microscopes.
Not anymore. Lin Li and colleagues report a new way using tiny beads to resolve images at 50 nanometers, shattering the limit for what can be seen in optical light. Their technique, reported in Nature Communications, makes use of “evanescent waves“, emitted very near an object and usually lost altogether. Those beads are called microspheres—they’re tiny glass balls about the size of red blood cells. Image: Nature Publishing Group.
