Optical Metasurface Captures Solar Magnetic Fields

|
By Rachel Berkowitz
| Fixing the Future
A new nanopatterned structure based on sub-wavelength physics has proved its value in a real-world setting, and it could qualify for use in outer space. The device, integrated with one of the world’s most advanced solar observatories, captured pictures of the Sun’s magnetic field in a new, advantageous way: via a single snapshot with no moving parts.

A new method could spot fentanyl variants no one has cataloged yet

| Science News Verified
Illicit laboratories do a criminally good job of synthesizing new forms of dangerous drugs that slip under the radar, but a new method could spot variants of the powerful opioid drug fentanyl even before they’ve been cataloged by authorities. Measuring a suspicious pill’s traits and comparing them to computer-generated reference values could reveal chemical signatures of previously unseen fentanyl variants, researchers report April 27 at bioRxiv.org.

June 3, 2026• Physics 19, s70 Size-dependent electrostatic barriers place an upper limit on droplet merging efficiency. F. Chen et al. [1]: adapted by APS/Carin Cain F. Chen et al. [1]: adapted by APS/Carin Cain × A well-shaken mixture of oil and vinegar will separate as the oil droplets eventually coalesce. Droplet growth, or coarsening, usually evolves according to standard rules. But puzzling exceptions persist.
