Amazon announced on Wednesday that it is eliminating approximately 16,000 roles across the company as part of organizational changes that began in October 2025 and are only now being finalized by certain teams. Senior Vice President Beth Galetti shared the news in a memo to employees, framing the reductions as an effort to reduce layers, increase ownership, and remove bureaucracy. The memo follows another memo that the company accidentally sent to employees.

# Asteroid 2024 YR4 Has a 4% Chance of Hitting the Moon
robot (spnet, 1) → All – 10:22:02 2026-01-28
An anonymous reader quotes a report from Universe Today: There's a bright side to every situation. In 2032, the Moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%), but non-negligible. And scientists are starting to prepare both for the bad (massive risks to satellites and huge meteors raining down on a large portion of the planet) and the good (a once in a lifetime chance to study the geology, seismology, and chemical makeup of our nearest neighbor). A new paper from Yifan He of Tsinghua University and co-authors, released in pre-print form on arXiv, looks at the bright side of all of the potential interesting science we can do if a collision does, indeed, happen. If Asteroid 2024 YR4 were to hit the Moon, researchers would be able to watch a large lunar impact unfold in real time and collect data on extreme collisions that usually exist only in computer models. Telescopes could follow how a newly formed crater and its pool of molten rock cool and solidify, while the resulting moonquake would offer a clearer picture of its internal structure via the seismic waves it sends through the Moon.
Furthermore, researchers could compare the fresh crater to older ones to improve our understanding of the Moon's long history of impacts. Debris blasted off the surface could even deliver small lunar samples to Earth.
Altogether, it would be a once-in-a-generation chance to learn more about how the Moon/rocky worlds respond to powerful impacts.

# Ancient Martian Beach Discovered, Providing New Clues To Planet's Habitability
robot (spnet, 1) → All – 08:22:01 2026-01-28
alternative_right shares a report from Phys.org: New findings from NASA's Perseverance rover have revealed evidence of wave-formed beaches and rocks altered by subsurface water in a Martian crater that once held a vast lake -- considerably expanding the timeline for potential habitability at this ancient site. In an international study led by Imperial College London, researchers uncovered that the so-called 'Margin unit' in Mars's Jezero crater preserves evidence of extensive underground interactions between rock and water, as well as the first definitive traces of an ancient shoreline.
These are compelling indicators that habitable, surface water conditions persisted in the crater (home to a large lake around 3.5 billion years ago) further back in time than previously thought. "Shorelines are habitable environments on Earth, and the carbonate minerals that form here can naturally seal in and preserve information about the ancient environment," said lead author Alex Jones, a Ph.D. researcher in the Department of Earth Science and Engineering (ESE) at Imperial. The findings have been published in the Journal of Geophysical Research: Planets.
