Evidence for Abiotic Dimethyl Sulfide in Cometary Matter
The Astrophysical JournalTechnological progress related to astronomical observatories such as the recently launched James Webb Space Telescope (JWST) allows searching for signs of life beyond our solar system, namely, in the form of unambiguous biosignature gases in exoplanetary

Updated Interior Structure of Callisto From a Reanalysis of Galileo Data
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract The internal structure of Callisto has been a long‐standing question since the Galileo mission. Previous analyses suggested a largely undifferentiated interior. We present an updated interior structure for Callisto derived from a reanalysis of Galileo's Doppler tracking data using new signal processing techniques.

Status of the COMET experiment [PDF]
, 2018 The COMET experiment, currently under construction at J-PARC, is designed to search for the the neutrinoless flavour-changing charged-lepton process μ- + A → e- + A, which is a promising channel to look for new physics.

The next step for Rosetta ROSINA/DMFS data of comet 67P/Churyumov-Gerasimenko: the search for semi-volatiles species. [PDF]
, 2021 Using data from Rosetta/ROSINA's Double Focusing Mass Spectrometer (DFMS), a zoo of neutral molecules have been discovered in the coma of 67P/Churyumov-Gerasimenko, which led to a wealth of new insights regarding the comet itself, its formation and the ...

Covertly Active Comet (139359) 2001 ME1
The Planetary Science JournalOn 2018 November 18, coronagraphs onboard the Solar and Heliospheric Observatory (SOHO) captured an unrecognized comet crossing its fields of view. We identified this comet to be the minor planet (139359) 2001 ME _1 , whose previously unnoticed dust ...

Multiple Outbursts of Halley-type Comet 12P/Pons–Brooks
The Astronomical JournalWe present optical observations of the Halley-type comet 12P/Pons–Brooks (12P) on its approach to perihelion. The comet was active even in the first observations at ∼8 au.

Down But Not Out: The Case of Long-period Comet C/2021 O3 (Panstarrs)
The Astronomical JournalWe combine ground- and space-based observations of long-period comet C/2021 O3 (Panstarrs; perihelion distance 0.287 au) in order to investigate its reported near-perihelion destruction.

Olfaction in the Colorado beetle at the onset of host plant selection [PDF]
, 1979 Long-range olfactory orientation of the adult Colorado beetle was studied in a low- speed wind tunnel. The odour of fully grown potato plants elicits an upwind locomotory response in Colorado beetles (odour-conditioned positive anemotaxis), and increases
