As we experience record breaking heat, intense heat waves, & drought, it's critical to understand how short-term & long-term exposures are increasing risk of dehydration, particularly in water-insecure settings & with vulnerable groups. doi.org/10.1002/ajhb...

Increased Vulnerability to Dehydration Due to Heat Stress and Drought Across Reproductive States for Pastoralist Women in Northern Kenya

The executive branch does not have the legal right to cancel appropriated spending or eliminate agencies created by Congress. Trump and Musk are doing both. Entirely lawless and unconstitutional. The world's largest provider of food assistance shut down. www.washingtonpost.com/politics/202...
Musk tweet boasting of "feeding USAID into the chipper"“I went over it with him in detail, and he agreed that we should shut it down,” Musk said. “And I actually checked with him a few times [and] said ‘are you sure?’”

The answer was yes, he said.

“And so we’re shutting it down,” Musk said.

USAID staffers were told that the agency’s headquarters in Washington will be closed Monday amid the turmoil.

In an email to staff early Monday, the agency’s leadership said: “Agency personnel normally assigned to work at USAID headquarters will work remotely … with the exception of personnel with essential on-site and building maintenance functions individually contacted by senior leadership.”
