Israeli startup Watergen, which has developed a technology to produce water from air, has installed a generator for a Navajo Nation Native American community in Arizona to help them deal with a crippling water shortage.

The first generator was set up at the Rocky Ridge Gas & Market in northeast Arizona and aims to address the lack of access to clean drinking water within the Hard Rock community there, according to a joint press statement issued Thursday.

Nearly 10,000 families across Navajo Nation lack access to running water, per recent estimates. Local groundwaters have been contaminated over the years by mining and the situation has been exacerbated by the devastating drought affecting the Western United States.

In a recent study published in the journal Scientific Reports, researchers explored how changes in daily step counts and variability affect cognitive function in older adults during a 10-week physical activity intervention.

Background

A research team consisting of Professor Kyoung-Duck Park and Hyeongwoo Lee, an integrated PhD student, from the Department of Physics at Pohang University of Science and Technology (POSTECH) has pioneered an innovative technique in ultra-high-resolution spectroscopy. Their breakthrough marks the world’s first instance of electrically controlling polaritons – hybridized light-matter particles – at room temperature.

This research has been published in Physical Review Letters (“Electrically Tunable Single Polaritonic Quantum Dot at Room Temperature”).

“In the case of Iztapalapa, water scarcity has always been a big problem,” said Mariano Salazar, a 69-year-old community leader in the district. “There are almost 2 million of us in this municipality and we require 100 million cubic meters of water a year.”

Frustrations over the situation have fueled unrest. In January, protesters in the municipality of Acambay forced open the gate of an office of Mexico’s National Water Commission and broke windows, as reported by Reuters.

Local authorities have urged residents to conserve water and prioritize what is available for drinking, particularly as temperatures this week hover around 85 F.
