Peekaboo is a delightful game to play with infants. Lacking as they are in object permanence, the act of hiding your face from a baby before revealing it with a flourish is sure to raise a smile, as their little brains try to figure out what on Earth is going on.
It’s somewhat less fun to play this game with the richest and most powerful nation on the planet, but that hasn’t stopped the Trump administration from giving it a try.
For decades, US federal agencies have carried out detailed surveys of public health that have informed policy on everything from combatting drug addiction to food insecurity. But these data-gathering exercises are now being cut or cancelled altogether (see, US public health system is flying blind after major cuts).

By metaphorically covering its eyes, the US government seems to hope that these problems will simply go away, but the opposite is true.
As we learned during the height of the covid-19 pandemic, data, surveillance and preparation all go hand in hand when it comes to preventing disaster. Statistical agencies and other data gatherers aren’t merely clipboard worriers, but clipboard warriors – our first line of defence against the unknown.

While not all heroes wear capes, some do their best to fashion one out of a spreadsheet

The US isn’t the only nation that seems to have forgotten this. For some years now, the UK’s Office for National Statistics, once seen as world-class, has been , in part due to underfunding of its activities.
Part of the problem is that this type of work has a boring public image. No politician ever got elected by promising a survey in every letterbox, and statisticians are unlikely to become superstars.
But that has to change. While not all heroes wear capes, some do their best to fashion one out of a spreadsheet, and this type of data drudgery must be applauded and supported. Governing without object permanence is a bad idea, as the US is unfortunately about to find out.
![Astronomers have long known that understanding how star clusters come to be is key to unlocking other secrets of galactic evolution. Stars form in clusters, created when clouds of gas collapse under gravity. As more and more stars are born in a collapsing cloud, strong stellar winds, harsh ultraviolet radiation and the supernova explosions of massive stars eventually disperse the cloud, and their light can bear down on other star-forming regions in the galaxy. This process is called stellar feedback, and it means that most of the gas in a galaxy never gets used for star formation. Researching how star clusters develop can answer questions about star formation at a galactic scale. Now, the state of the art has been further developed with both Hubble and Webb working together to provide a broad-spectrum view of thousands of young star clusters. An international team of astronomers has pored over images of four nearby galaxies from the FEAST observing programme (#1783), trying to solve this mystery. Their results show that it is the most massive star clusters that clear away their gaseous shroud the fastest, and begin lighting their galaxy the earliest. The team identified nearly 9000 star clusters in the four galaxies in different evolutionary stages: young clusters just starting to emerge from their natal clouds of gas, clusters that had partially dispersed the gas (both from Webb images), and fully unobstructed clusters visible in optical light (found in Hubble images). With Webb???s ability to peer inside the gas clouds, they were able to then estimate the mass and age of each cluster from its light spectrum. This image shows a section of one of the spiral arms of Messier 51 (M51), one of the four galaxies studied in this work, as seen by Webb???s Near-Infrared Camera (NIRCam). The thick clumps of star-forming gas are shown here in red and orange, representing infrared light emitted by ionised gas, dust grains, and complex molecules such as polycyclic aromatic hydrocarbons (PAHs). Within these gas complexes, each tens or hundreds of light years across, Webb reveals the dense, extremely bright clusters of massive stars that have just recently formed. The countless stars strewn across the arm of the galaxy, many of which would be invisible to our eyes behind layers of dust, are also laid bare in infrared light. [Image description: A large, long portion of one of the spiral arms in galaxy M51. Red-orange, clumpy filaments of gas and dust that stretch in a chain from left to right comprise the arm. Shining cyan bubbles light up parts of the gas clouds from within, and gaps expose bright star clusters in these bubbles as glowing white dots. The whole image is dotted with small stars. A faint blue glow around the arm colours the otherwise dark background.]](https://images.newscientist.com/wp-content/uploads/2026/05/13114322/SEI_296271016.jpg)
