Researchers have long observed that a common family of environmental bacteria, Comamonadacae, grow on plastics littered throughout urban rivers and wastewater systems. But exactly what these Comamonas bacteria are doing has remained a mystery.

Brain scan study shows what happens in the brain when a person with schizophrenia hears voices
Patients with certain mental disorders, including schizophrenia, often hear voices in the absence of sound.
Auditory hallucinations are likely the result of abnormalities in two brain processes: a broken corollary discharge that fails to suppress self-generated sounds, and a noisy efference copy that makes the brain hear these sounds more intensely than it should. That is the conclusion of a study published October 3 in the open-access journal PLOS Biology by Xing Tian, of New York University Shanghai, China, and colleagues.
In the new study, researchers carried out electroencephalogram (EEG) experiments measuring the brain waves of 20 patients diagnosed with schizophrenia with auditory hallucinations and 20 patients diagnosed with schizophrenia who had never experienced such hallucinations.
A new era of solar observation: International team produces global maps of coronal magnetic field
For the first time, scientists have taken near-daily measurements of the sun’s global coronal magnetic field, a region of the sun that has only been observed irregularly in the past. The resulting observations are providing valuable insights into the processes that drive the intense solar storms that impact fundamental technologies, and thus lives and livelihoods, here on Earth.
Mercury’s magnetic landscape mapped in 30 minutes
As BepiColombo sped past Mercury during its June 2023 flyby, it encountered a variety of features in the tiny planet’s magnetic field. These measurements provide a tantalizing taste of the mysteries that the mission is set to investigate when it arrives in orbit around the solar system’s innermost planet.
