Inhaling Moon Dust Is Somehow Less Toxic Than Urban Air Pollution
During the Apollo missions, NASA operated out of an abundance of caution to ensure that astronauts didn't track back by planet-threatening microorganisms from the Moon. However, the conditions on Earth might be more dangerous to human life in one specific way. A study by the University of Technology Sydney published last month found that moon dust was far less toxic to our pulmonary system than the air pollution someone would encounter in a city.
The study suggests that inhaling moon dust won't cause long-term damage to our airways. Tests showed lunar material didn't trigger significant oxidative stress to lung cells, dissuading the fears provoked by the uncomfortable experiences of Apollo astronauts and other NASA personnel after the missions from a half-century ago. Now, if you're in the exclusive club of scientists with access to powdered lunar regolith, I wouldn't whip out your I.D. badge to start snorting lines of moon dust for a laugh. Michaela B. Smith, lead researcher and Ph.D student, said:
"Any dust, if you inhale it, you'll sneeze, cough, and have some physical irritation. But it's not highly toxic like silica, where you end up with silicosis from being on a construction site for 10 years. It's not going to be something like that."

The researchers emphasized the critical difference between mechanical damage and toxicity. Moon dust is still infamously abrasive. The study noted the irregular shape and rough edges of the dust. According to Space.com, statically-charged lunar dust would stick to space suits during Apollo's moon walks. This became a serious issue when astronauts returned to the Lunar Module. Once inside, the dust would sting the crew's eyes, cause a sore throat and sneezing. The same thing would happen once the flight surgeon unpaced the suit back on Earth.
This new research will be used for Artemis III, NASA's first crewed return to the Moon since Apollo 17 in 1972. The mission is still scheduled for 2027 after numerous delays caused by development issues. However, the entire program has been jeopardized by the Trump administration's funding cuts and cancellation of the SLS rocket program. If Artemis continues, there are plans for a permanent human presence on the surface. Without the looming threats of long-term health issues, NASA could use moon dust to build its base on the surface.

Too hot for the electric grid to handle?
The heat wave scorching large swaths of the country is stressing out the aging electric grid, threatening rolling blackouts when people need air conditioning most. To help keep ACs humming, the Trump administration is allowing some fossil fuel power plants in the Southeast to exceed pollution limits. While not an unprecedented move during emergencies, it marks a big contrast with other solutions that have emerged in recent years — such as Texas' reliance on solar power to get through heat waves. President Donald Trump's strategy to lean on fossil fuels creates a feedback loop: The more natural gas and coal are burned for energy, the more carbon pollution enters the atmosphere. This pollution helps warm the planet — requiring more electricity to cool people off. And without long-term planning for clean, reliable backup power, the short-term need to beat the heat dominates. That's why Energy Secretary Chris Wright authorized Duke Energy to run some power plants in the Carolinas at maximum output as temperatures approach 100 degrees, writes Jeffrey Tomich. 'Americans should not be forced to wonder if their power grid can support their homes and businesses,' Wright said in a statement. The heat dome is bearing down on much of the eastern U.S., from northeast Texas to New England, driving triple-digit heat and humidity in some areas. Scores of cities are under heat advisories, and more than 40,000 customers in several New York City boroughs lost power earlier this week as the temperatures stressed the local electric grid. Extreme heat is the leading weather-related cause of death in the country, killing more U.S. residents each year than hurricanes, floods and tornadoes combined, federal data shows. And it's not an equal-opportunity killer. In addition to directly causing dehydration or heat stroke, extreme heat can also worsen underlying health conditions. Research shows that already vulnerable populations, such as those without permanent housing, are more likely to have chronic conditions such as diabetes or cardiovascular disease. Lack of access to AC, medical care or nutrition only worsens the problem. Hotter days also mean higher utility bills. The summer heat is expected to drive up residential electricity bills by about 3 percent to an average of $178 per month, according to an analysis by the U.S. Energy Information Administration. That number could be even higher if temperatures continue to soar, EIA noted. It's Wednesday — thank you for tuning in to POLITICO's Power Switch. I'm your host, Arianna Skibell.

Power Centers Science agency booted from HQThe National Science Foundation has been kicked out of its headquarters in Alexandria, Virginia, to make space for the Department of Housing and Urban Development, write Robin Bravender and Ellie Borst. Where NSF employees will go next, they don't know. HUD Secretary Scott Turner announced the takeover today at a new conference, but offered no insights about where NSF employees would be relocated. He said his agency was moving in to start a new 'golden age.' Trump's newest plan to kill EPA grantsThe Trump administration is taking the unusual step of trying to cut funding and eliminate programs it dislikes by using routine administrative actions, write Jean Chemnick and Miranda Willson. The goal is to block billions in Environmental Protection Agency grants that the Biden administration had signed binding contracts to pay. But some scholars say Trump's mechanism is legally dubious at best. 'Their bureaucratic jujitsu is impressive, but it's also illegal,' said Jillian Blanchard with Lawyers for Good Government. How a little green law set off a political explosionThe European Commission set off a political cluster bomb last week when it suddenly declared it was killing a relatively minor rule on corporate greenwashing, writes James Fernyhough. The announcement came two days after the center-right European People's Party, the largest force in the European Parliament, sent a letter to the commission saying it wanted the law dead. That has fueled a growing sense among the center-left bloc that the right wing is controlling not just Parliament, but also the commission.

Jim Cramer on Keurig Dr Pepper: 'I Don't Want to Touch That One'
Keurig Dr Pepper Inc. (NASDAQ:KDP) is one of the 12 stocks on Jim Cramer's radar recently. A caller asked if the company would be able to compete with Coca-Cola long term despite its 'high debt'. In response, Cramer said: 'Yeah, no, I don't want to touch that one. I think if you want to be in that space, you want to be in Coca-Cola. I think Coca-Cola has demonstrated, first of all, I don't want to be in that space because there's just… the Secretary of Health and Human Services is against it. The GLP-1s, the new one from Amgen, just makes it tougher and tougher. You don't want to be in the space…' A conveyor belt filled with assorted K-Cup pods, ready for packaging. Keurig Dr Pepper (NASDAQ:KDP) produces and distributes a wide range of beverages and single-serve brewing systems, including branded concentrates, ready-to-drink products, and coffee-related goods. Oakmark Select Fund stated the following regarding Keurig Dr Pepper Inc. (NASDAQ:KDP) in its Q4 2024 investor letter: 'Keurig Dr Pepper Inc. (NASDAQ:KDP) is one of North America's leading beverage companies, with dominant positions in single-serve coffee and flavored soft drinks. The soft drink portfolio has an impressive track record of volume growth and market share gains. We believe this performance can continue due to favorable demographic trends, brand strength, and distribution advantages. Recently, weakness in the Keurig coffee division caused the stock price to come under pressure. However, we believe these industry-wide challenges will prove transitory because coffee remains a popular beverage. Keurig's coffee division is poised to capitalize on this demand with the largest installed base of single-serve brewers and ample runway to increase household penetration. At the current quote, the market ascribes minimal value to Keurig. We were happy to purchase shares in this above-average business at a discount to the market multiple, other beverage peers and private market transactions.' While we acknowledge the potential of KDP as an investment, we believe certain AI stocks offer greater upside potential and carry less downside risk.
