Kha Tu Ngoc rests in her two- square- meter house in Ho Chi Minh City on May 2, 2018. The “micro- house” dwellings are dotted throughout Vietnam' s bustling southern hub, occupied by families clinging to postage stamp- sized plots a city developing at breakneck pace. Tucked away in winding alleys, nestled under new condo developments or sandwiched between street food stalls and shops, the tiny houses are easily missed by the unattentive passerby.

A photographer has created a series of paw-traits of hungry dogs pulling hilarious faces as they try and catch treats. Using a unique technique, the shots are captured at the exact moment the adorable pooches attempt to catch an airborne piece of food. The dogs appear surprised, happy, sad, confused – and sometimes even so blasé they miss the treat entirely. The images were taken by Christian Vieler, a photographer from Waltrop, Germany. Here: A labrador retriever. (Photo by Christian Vieler/Caters News)

Lucha libre is Mexico’s version of what in the United States refer to as pro wrestling. Its dates to 1863, when a Mexican wrestler named Enrique Ugartechea developed a form of “freestyle” wrestling that was based on Greco-Roman wrestling. Lucha libre began to soar in popularity in Mexico after two Italian businessmen started promoting fights in the early 1900s. It has since become popular around the globe.
