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

A magnetic field that kills superconductivity can also bring it back

Magnetic fields are generally known to destroy superconductivity in a material. However, in exceptional cases, they can lead to what is known as "re-entrant superconductivity"—where superconductivity disappears as expected, but then unexpectedly returns when the magnetic field is

X-ray snapshots reveal how viral shells change shape as they dry out

When viruses travel through the air in tiny droplets, they can quickly start to dry out. Yet many viruses remain infectious after rehydration—something that is still not fully understood. Now, an international team of researchers has directly observed at the European XFEL how the

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

How longer exciton lifetimes could ease efficiency trade-off in organic solar cells

Although the efficiency of organic solar cells has now risen to more than 20%, there are physical limits that make it difficult to further increase their performance. A research team from Linköping University in Sweden, the University of Potsdam, the Paul-Drude-Institut in Berlin

'Super-puff' planets lighter than candy floss discovered by international team

An international collaboration has discovered two of the lowest-density giant planets ever detected: rare "super-puff" planets with densities lower than candy floss. The study—led by the University of Oxford, in collaboration with Université Côte d'Azur/Observatoire de la Côte d'
