If you've been suffering through the high temperatures that have scorched much of the country this summer, you know the toll it can take on your body, leaving you dizzy, dehydrated and, in some severe cases, at risk of death. But there's another lesser-known impact of extreme heat — and it might surprise you.
Here's what else you need to know to start your week smart.
🔦 Few US government agencies have navigated as much turmoil in recent months as NASA.
With the impending loss of thousands of jobs looming, this week saw the release of a scathing letter from nearly 300 current and former NASA employees and the abrupt resignation of the director of the Goddard Space Flight Center.
Scientists and agency workers criticized budget cuts, grant cancellations and a 'culture of organizational silence.' They also raised concerns about suggested changes to a system of safety checks and balances.
President Donald Trump appointed US Secretary of Transportation Sean Duffy as interim NASA administrator to replace Janet Petro, a longtime agency employee. That came after the nomination of tech billionaire Jared Isaacman to lead NASA was rescinded.
Some scientists are criticizing the agency as the Trump administration tries to dismantle the NASA Goddard Institute for Space Studies, one of the country's top climate labs. Employees are working remotely after their New York City office was shut down.
Back in March, NASA astronauts Suni Williams and Butch Wilmore returned to Earth after gaining international attention as their short trip to space stretched into a saga lasting more than nine months. It's an example of how quickly things can go sideways. Meanwhile, leaks have plagued the International Space Station.

The International Monetary Fund will release its July 2025 World Economic Outlook Update. This publication provides analyses and projections of the global economy. In an update in April, the IMF said forecasts for global growth had been revised markedly down compared with its January update, reflecting effective tariff rates at levels not seen in a century.
The Federal Reserve is set to conclude its fifth interest rate meeting since President Donald Trump returned to office in January, with policymakers expected to hold rates steady once again. The decision is likely to draw sharp criticism from Trump, who has repeatedly clashed with Fed Chair Jerome Powell over the bank's refusal to cut rates. Tension between the two was evident last week during a tour of the Fed's $2.5 billion headquarters renovation, a project the Trump administration has used to intensify pressure on Powell. 📹 Watch this awkward exchange between Powell and the president.
The National Transportation Safety Board will begin a three-day public hearing to investigate the January 29 mid-air collision between a regional jet and an Army helicopter over the Potomac River near Washington, DC, that killed 67 people.
President Trump's so-called reciprocal tariffs are set to go into effect on August 1 after a 90-day delay, impacting multiple countries, including Mexico, Canada and the European Union. If Trump's proposed duties of 30% do kick in, Americans could wind up paying more for everything from produce to medical equipment, electronics and alcohol.
It's also the day we get the monthly jobs report for July.
