Almost 40 years ago, Joseph Borzelleca published a study on the food coloring Red No. 3. The FDA cited his work when banning the additive in January. But the researcher says the dye is safe

"From our perspective down in the trenches actually working for the government, it feels like the people up top just have no clue about anything."

While unraveling the mystery of why some planet-forming disks fall onto their stars, an astronomer stumbled upon a surprise: a hidden star.

The Space Telescope Science Institute (STScI) has announced the science objectives for Webb's General Observer Programs in Cycle 4 (Cycle 4 GO) program. The Cycle 4 observations include 274 programs that establish the science program for JWST's fourth year of operations, amounting to 8,500 hours of prime observing time. This is a significant increase from Cycle 3​ observations and the 5,500 hours of prime time and 1,000 hours of parallel time it entailed.

A distant trio of worlds may shed light on planetary formation in the early solar system. Sometimes, good things come in threes. If astronomers are correct, a system in the distant Kuiper Belt may not be two but three worlds, offering an insight into formation in the early solar system. The study comes out of researchers at Brigham Young University and the Space Telescope Science Institute.

The increasing frequency of so-called ‘1-in-a-1000-year' weather events highlights how global warming is disrupting rather more typical weather patterns beyond what scientific models can reliably predict. A recent paper proposes a three-tier scientific approach for addressing these unprecedented climate challenges: improving rapid response capabilities, making incremental infrastructure adaptations, and pursuing transformational system changes to manage escalating climate chaos.

Former Google CEO Eric Schmidt has assumed the top job at the startup Relativity Space, which aims to compete with SpaceX and other big launch companies.
