Astronomers detect seismic ripples in ancient galactic disk
A new snapshot of an ancient, far-off galaxy could help scientists understand how it formed and the origins of our own Milky Way. At more than 12 billion years old, BRI 1335-0417 is the oldest and furthest known spiral galaxy in our universe. The researchers were able to not only capture the motion of the …

Organic compounds in asteroids formed in colder regions of space
Analysis of organic compounds — called polycyclic aromatic hydrocarbons (PAHs) — extracted from the Ryugu asteroid and Murchison meteorite has found that certain PAHs likely formed in the cold areas of space between stars rather than in hot regions near stars as was previously thought. The findings open new possibilities for studying life beyond Earth …

Springs aboard — gently feeling the way to grasp the microcosmos
The integration of mechanical memory in the form of springs has for hundreds of years proven to be a key enabling technology for mechanical devices (like clocks), achieving advanced functionality through complex autonomous movements. In our times, the integration of springs in silicon-based microtechnology has opened the world of planar mass-producible mechatronic devices from which …

Researchers 3D print components for a portable mass spectrometer
Researchers 3D printed a mini quadrupole mass filter, a key component of a mass spectrometer, that performs as well as some commercial-grade devices. It can be fabricated in hours for a few dollars and is one step toward producing a portable mass spectrometer that could enable effective medical diagnoses or chemical analyses in remote areas. …
