Liquid ripples rewrite 130-year-old biological classic: New reflections on the lock-and-ke

This April, when the spring breeze carried the formal acceptance notice of our paper by the Journal of the American Chemical Society to my desk, my thoughts instantly drifted back to the late Phil Geissler. A legendary physical chemist and the original spark for this research, Ge

Solar blast's magnetic cloud grew by one-fifth en route to Earth, spacecraft reveal

A University of Iowa-led physics team has detailed the extreme expansion of a magnetic cloud that originated from a huge, gaseous explosion on the sun. In a new study, the researchers describe the inflated magnetic cloud as recorded by spacecraft in separate, fortuitous locations

Organic carbon detected in Bright Angel rock formation on Mars

In September 2025, NASA announced that its Perseverance rover had discovered a potential biosignature, which is a substance or structure that might have a biological origin. A new paper, published in Science Advances, unambiguously confirms the detection of organic carbon, the bu

A single origin story for the Milky Way's most mysterious stars

Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied explanation. Astronomers have proposed various competing t

Why Europe's rising plant diversity may signal habitat disruption, not ecological recovery

The number of plant species in many ecosystems in Europe has grown rather than shrunk over the last 100 years. However, this is not necessarily cause for celebration, as this local increase is primarily due to generalists and non-native species, which compete with the original na

Earth microbes can survive individual martian hazards—and evade astronaut immune systems

Hopefully, we're about to travel back to the moon relatively soon. And while the original "giant leap for mankind" was taken by a human, Neil Armstrong brought a plethora of other forms of life along with him. Humans themselves are essentially walking ecosystems, and understandin

Evolutionary origins of 'junk DNA' may provide new clues to cancer

In cancer research, one person's junk is increasingly becoming another person's treasure. Scientists have uncovered new evidence showing how recently evolved "junk DNA" genetic elements can become integrated into ancient cellular pathways that regulate cancer. These findings may
