A customer displays a bag of "flower", or marijuana bud, that she purchased at an unlicensed cannabis dispensary in unincorporated Los Angeles County, just east of the Los Angeles city boundary, on December 21, 2022. - Unlicensed marijuana dispensaries use a variety of green signs, ornaments, and lettering to let customers know cannabis is for sale at the location. A 2016 referendum legalized recreational use of cannabis in California, 20 years after it was permitted for medical use with a prescription. The idea was to rid the streets of illegal sellers, to regulate the substance to ensure it was of sufficient quality, and to raise tax for state coffers -- goals shared by other jurisdictions, including Canada, Uruguay and Germany. The first legal shops opened in 2018, and are now found in many major cities. (Photo by Robyn BECK / AFP) (Photo by ROBYN BECK/AFP via Getty Images)

A woman holds a cut half of a plant-based patty with a meaty taste, made and cooked by a robot according to customer requirements, offered by Israeli fast food brand BBB in the Israeli coastal town of Herzliya on December 28, 2021. - The Israeli fast food restaurant BBB is serving up a veggie steak made and cooked by a robot that tailors ingredients and cooking time to customer tastes. Customers can use an app to choose the amount of vegetable protein or fat in their "steak", as well as its size and how they want it cooked, she said. The "robot chef", which is the size of a large oven, can make three different steaks simultaneously -- though a human staff member makes up the burgers.

<p>La educación permite a las niñas transformar sus vidas, pero para muchas familias pobres de todo el mundo, comprar el uniforme escolar necesario es un obstáculo colosal. Esta es una de las razones por las que 129 millones de niñas de todo el mundo no van a la escuela. Payton McGriff, oriunda de Idaho, abordó el problema en el marco de un proyecto de la universidad y semanas más tarde acabó investigando soluciones en un viaje de estudios a Togo. Hoy, su ONG S H E (Style Her Empowered) provee a 1.500 niñas de Togo de material escolar, clases particulares y uniformes innovadores diseñados para crecer con ellas, confeccionados localmente por mujeres que también reciben oportunidades educativas gratuitas.</p>
