Black TV producer on way to Emmys party mistaken for bank robber, handcuffed, held for six hours
An African-American film producer in Beverly Hills for an Emmy pre-party was handcuffed and detained for around six hours on Friday night as police believed he fit the description of a suspect in a nearby bank robbery.
Charles Belk said he left a restaurant alone to refill a parking meter when he was suddenly surrounded by six police cars “handcuffed very tightly, fully searched for weapons, and placed back on the curb,”  he wrote on his Facebook page with an accompanying photo of him sitting on the curb as two police officers stand close by.

Möbius’ strip (or Möbius’ band) is named after August Ferdinand Möbius (1790-1868). This is probably the most famous of all one-sided surface. To create a cylinder, take a strip of paper, bent it to join the two ends. For Möbius’ strip, the procedure is rather the same, except, before joining the ends, turn one of them half a turn, i.e. 180°, and then apply glue. Also, cutting Möbius’ strip also leads to unexpected results. 

  • Cut your band down the center line all the way around, what will happen…EX: Figure 7- 1 half turn, M = 3, the middle layer removed  & Figure 8: 2 half turns, M = 3, the middle layer removed.
  • Cut 1/3 in form edge, all the way around., what will happen….
  • What happens with two twists or more…

Topology is the mathematical study of the spatial properties that are preserved through the deformation, twisting and stretching of objects. Topological architectures are common in nature and can be seen, for example, in DNA molecules that condense and relax during cellular events 1. Synthetic topological nanostructures, such as catenanes and rotaxanes, have been engineered using supramolecular chemistry, but the fabrication of complex and reconfigurable structures remains challenging 2. Here, we show that DNA origami 3 can be used to assemble a Möbius strip, a topological ribbon-like structure that has only one side 4, 5, 6. In addition, we show that the DNA Möbius strip can be reconfigured through strand displacement 7 to create topological objects such as supercoiled ring and catenane structures. This DNA fold-and-cut strategy, analogous to Japanese kirigami 8, may be used to create and reconfigure programmable topological structures that are unprecedented in molecular engineering. (Source)
