Scientists used Earth’s magnetic field and atmosphere as a planet-sized detector to search for ultralight dark matter. The method tightened limits on axions and found several unexplained signals that could be linked to dark photons, though they are not yet evidence of dark matter.

Scientists may have detected new signs of dark matter, the invisible substance thought to help hold galaxies and the wider universe together. The evidence is not yet confirmed as the discovery of a specific particle.

Researchers at UC San Diego showed that RNA polymerase, a key enzyme in gene expression, can accurately read DNA built from an eight-letter genetic alphabet. Imaging showed that the synthetic letters interact with the enzyme in ways that closely resemble natural DNA letters.

German launch company Isar Aerospace says its 28-metre Spectrum rocket reached space after launching from Andøya Spaceport in Arctic Norway. The flight marks a major test of Europe’s effort to build independent commercial launch capacity.

Scientists used Earth’s magnetic field and atmosphere as a planet-sized detector to search for ultralight dark matter. The method tightened limits on axions and found several unexplained signals that could be linked to dark photons, though they are not yet evidence of dark matter.
The key shift is methodological: Earth itself can serve as a detector for particles too

The study expands the search for dark matter while showing that intriguing signals still fall short of discovery.
Summary
Scientists may have detected new signs of dark matter, the invisible substance thought to help hold galaxies and the wider universe together. The evidence is not yet confirmed as the discovery of a specific particle.
The key shift is from dark matter as an inferred cosmic effect to a possible

A verified dark matter particle would explain a major gap in our understanding of how the universe is structured.
Summary
Researchers at UC San Diego showed that RNA polymerase, a key enzyme in gene expression, can accurately read DNA built from an eight-letter genetic alphabet. Imaging showed that the synthetic letters interact with the enzyme in ways that closely resemble natural DNA letters.
The key shift is that an expanded genetic alphabet can now pass a central test

Scientists recognized Pristimantis milpe as a distinct frog species after reexamining museum specimens collected in the 1800s. The frog had previously been misidentified despite being widespread across parts of Ecuador and Colombia.

Researchers found that pterostilbene, a compound present in blueberries, grapes, and other berries, reduced abnormal fat accumulation in cultured mouse muscle cells. It appeared to work by increasing fat breakdown and stabilizing a protein involved in fatty acid metabolism.

Researchers are using AI to analyze large collections of animal vocalizations, including crow calls, to identify patterns that may reveal how different species communicate. The approach could deepen human understanding of animals while raising concerns about privacy, exploitation and the uses of such knowledge.

Scientists observed quantum oscillations in zirconium pentatelluride under temperatures near absolute zero and magnetic fields as high as 60 tesla. The oscillations persisted beyond the point where established models predicted they should vanish, revealing electron behavior that current theories do not fully explain.
