A NASA program is recruiting citizen scientists to measure snowpack in the backcountry of the Pacific Northwest and Alaska, according to the Associated Press.

Why it matters: The measurements are used to estimate how much water is being held in the snow, and therefore how much will be released into rivers and reservoirs in the area. In the western U.S., "nearly three-fourths of annual stream flow that provides drinking water comes from spring and summer melt," writes the AP's Dan Joling. Researchers want to improve the accuracy of measurements so that simulations can better predict the effect of snowmelt on a watershed.

How it works: Participants can measure snow depth with an avalanche probe, something most people hiking in these areas already carry, David Hill, a professor at Oregon State University and one of the researchers on the program told the AP. The measurements are then entered into a smartphone app, which records the location and time of measurement.

  • Gabriel Wolken, a research geologist with the Alaska Division of Geological & Geophysical Surveys, told the AP, "the hundreds of measurements collected far outpaced what the scientists could gather."
  • Hill said the input from the public is cutting errors "in our modeled snow-water equivalent...by about 90 percent."
  • The program, called Community Snow Observations, is meant to complement snow telemetry stations that also provide measurements though there aren't many of them due to installation and maintenance costs, said Hill.

A Hollywood workers' union reached a tentative deal with studios, networks and streamers that will guarantee better working conditions, meal breaks and increased wages for low-paid workers, the International Alliance of Theatrical Stage Employees (IATSE) announced Saturday night.

Why it matters: The deal, which still needs to be ratified by IATSE members, will avert a nationwide strike by film and television workers that was set to start Monday. It would have been the first strike in the union's 128-year history.

Former President Bill Clinton was discharged from the University of California, Irvine Medical Center on Sunday, nearly a week after he was admitted for a non-COVID-related infection, according to his spokesperson Angel Ureña.

What they're saying: "His fever and white blood cell count are normalized and he will return home to New York to finish his course of antibiotics," wrote Dr. Alpesh Amin, who has been overseeing the team of doctors treating Clinton. "On behalf of everyone at UC Irvine Medical Center, we were honored to have treated him and will continue to monitor his progress."

Worth noting: Clinton had a urinary tract infection that spread to his bloodstream, per CNN.

  • The California-based medical team had been administering IV antibiotics and fluids, and was in constant communication with Clinton's New York team, including his cardiologist, according to the former president's physicians.
  • President Biden spoke by phone with Clinton on Friday to see how he was doing, and the catch-up included a discussion of recent politics.
