Happening this morning: A key hearing in the cases challenging the NIH grant terminations.

Plaintiffs, including multiple state AGs + researchers, are requesting an injunction to reverse the terminations.

Column | See where your flights will experience this climate-fueled turbulence Studies show that climate-driven turbulence is expected to increase further in the coming decades. See how major flight routes in the U.S. could be affected

Column by Daniel Wolfe | Clear-air turbulence has increased since the 1970s. Researchers agree that the likelihood of severe turbulence will only increase in a warming world, putting passengers and crew at risk.

See how different plane routes could experience more turbulence:

Near-future rocket launches could slow ozone recovery - npj Climate and Atmospheric Science Rocket emissions thin the stratospheric ozone layer. To understand if significant ozone losses could occur as the launch industry grows, we examine two scenarios. Our β€˜ambitious’ scenario (2040 launches/year) yields a βˆ’0.29% depletion in annual-mean, near-global total column ozone in 2030. Antarctic springtime ozone decreases by 3.9%. Our β€˜conservative’ scenario (884 launches/year) yields βˆ’0.17% annual, near-global depletion; current licensing rates suggest this scenario may be exceeded before 2030. Ozone losses are driven by the chlorine produced from solid rocket motor propellant, and black carbon which is emitted from most propellants. The ozone layer is slowly healing from the effects of CFCs, yet global-mean ozone abundances are still 2% lower than measured prior to the onset of CFC-induced ozone depletion. Our results demonstrate that ongoing and frequent rocket launches could delay ozone recovery. Action is needed now to ensure that future growth of the launch industry and ozone protection are mutually sustainable.

The results of a study in npj Climate and Atmospheric Science shows that ongoing and frequent rocket launches could delay ozone recovery. The authors call for action to ensure that future growth of the launch industry and ozone protection are mutually sustainable. πŸ§ͺ

We know that training models on generated content causes model collapse (see autophagy).

So ironic: the more people populate the Internet with the results of these models put to their intended use, the less useful the internet becomes for training the next generation models.

It always boggles my mind that I, a journalist, am expressly forbidden from trading stocks, but members of Congress, with vastly greater knowledge of market-moving news, are allowed to profit by front-running markets, and so may profit by in essence stealing from the public they represent.

A reminder that if the government can send migrants to a prison camp without any due process, it can send U.S. citizens there, too. I know because this happened to me and my family in 1942.

Swarms of satellites are harming astronomy. Here’s how researchers are fighting back SpaceX and other companies plan to launch tens of thousands of satellites, which could mar astronomical observations and pollute the atmosphere.

The number of working satellites has soared in the past five years to around 11,000, mostly because of constellations of orbiters that provide Internet connectivity around the globe, but it comes with a series of problems. Nature explores the issues and how scientists are reacting. πŸ”­ πŸ§ͺ

The NTSB says it will no longer email news outlets or reporters with notifications of upcoming press conferences, including those on plane crashes in Washington and Philadelphia.

Instead, all notifications will be made on X.

We're filing a FOIA to find out more about the change in policy.

one thing i’m stuck on is this idea that β€œmasculine” energy means license to act like a chud in public, as opposed to more traditional notions of public masculinity, such as those that put a premium on the performance of integrity, honesty, honor and generosity.
