If you want to see the faint light from the first stars and galaxies that began shining at the end of the cosmic dark ages a few hundred million years after the Big Bang, you're going to need a big telescope. But not just any big telescope.
You're going to need to put it in space where it will have to operate at a few degrees above absolute zero to register the exceedingly faint infrared traces of that bygone era, detecting light that has been stretched out by the expansion of space itself over nearly 14 billion years.
To do that, you'll have to equip the observatory with a tennis court-size kite-shaped sunshade, made up of five membranes the thickness of a human hair, separated and pulled taught by scores of motor-driven stainless steel cables routed through dozens of pulleys.
On May 7, health influencer Paul Saladino, M.D.. posted a video to his X account that promoted feeding "raw dairy" to infants. The post received over 90,000 views and sparked strong backlash before it was removed the following day. Saladino regularly advocates for "animal-based" diets featuring raw milk, including on his TikTok channel where he has over half a million followers.
Everywhere you look, things are getting more complicated. Our phones have over a thousand settings. Showerheads come with apps. Cars have touchscreens. Ovens have touchscreens. "There's no doubt that 'featuritis' is real," said design consultant Jakob Nielsen. "Most of these things are too complicated."
New research is adding to the evidence linking ultra-processed foods to health concerns. The study tracked people's habits over 30 years and found those who reported eating more of certain ultra-processed foods had a slightly higher risk of death — with four categories of foods found to be the biggest culprits.
