Summary: Simulation of open quantum dynamics on quantum circuits has recently gained wide interest, with the development and demonstration of various quantum algorithms. Among them, a unitary dilation-based quantum algorithm has been designed to simulate general and complex physical systems. In this paper, we apply this quantum algorithm to simulate the dynamics of the radical pair mechanism in the avian compass. The simulation is conducted on the IBM QASM quantum simulator. This work represents the first application of any quantum algorithm to simulate the radical pair mechanism in the avian compass, demonstrating the generality of the quantum algorithm and opening up new opportunities for studying the avian compass with quantum computing devices.

Summary: A recently developed information theory approach provides a strict lower limit on the precision of a bird's head direction estimation using geomagnetic cues and a cryptochrome-based radical pair sensor. This study shows how adjusting the orientation of cryptochrome molecules, the distribution of cells around the retina, and the effects of the geomagnetic field on radical pair photochemistry can optimize the performance of the magnetic compass sense in night-migratory songbirds.

Summary: Agricultural ponds can serve as suitable habitats for Palmate Newts, although they are considered to have suboptimal characteristics compared to forested areas. Newts reproducing in forest ponds were found to be larger in size, but there were no differences in age and growth rate between habitat types. Forest ponds showed higher genetic diversity compared to agricultural ponds.

Summary: Research shows that juvenile Atlantic herring may use a time-compensated sun compass for orientation during their migration. Their swimming direction is still affected even when the sky is cloudy.

Summary: The study found that hoverflies use a time-compensated sun compass as their primary navigational mechanism during migration, and they tend to fly south and adjust their orientation under clear and sunny conditions.

Summary: The magnetic compass, as a backup navigation device, remains necessary and reliable, but requires regular adjustments to ensure accuracy. Current inspections of magnetic compasses are insufficient, and further investigation into the causes of deviation, particularly under varying conditions, is needed.

Summary: Red-headed Buntings use the Earth's magnetic field and other cues for navigation during migration. Weather conditions influence the timing of migration in Red-headed Buntings, but not the direction.

Summary: Research suggests that birds may learn to use the star compass during their growth rather than having an innate ability. Observing the stars in spring helps birds choose their migratory direction, while relying solely on daytime celestial cues may result in disorientation.

Summary: One of the most interesting features of avian magnetic compass is its sensitivity to weak oscillating magnetic fields. The pied flycatcher, a long-distance migrant, was disoriented by an OMF with an amplitude of 190 nT, but showed correct migratory direction when tested with an OMF of 17 nT. Interestingly, the sensitivity of the pied flycatcher to OMF is higher than that of the European robin and the garden warbler.

Summary: This study reveals that newts rely on light and the ambient magnetic field during evening twilight to determine their home direction, as the temporal variation in the magnetic field is minimal during this period. Additionally, it shows that newts use a light-dependent magnetic compass to align a 'map detector' relative to the magnetic field and obtain map information for orientation.

Summary: The goldsinny wrasse is a commercially important fish that exhibits seasonal migration behaviors. Research shows that male goldsinny wrasse have a magnetic compass to locate their home territories, while females do not possess this ability.

Summary: Hypogean petrels return to the same nest burrow to breed on remote islands during the summer months. Behavioral experiments showed that olfactory cues are sufficient to allow nest identification. An analysis of volatile organic compounds (VOCs) from blue petrel nests indicated that the nest air odor mainly consists of the owners' odor, providing a stable chemical label for nests throughout the breeding season.

Summary: Functional asymmetries of the avian visual system can be studied by occluding one eye. The study found that pigeons using the left eye/right hemisphere system exhibited slower learning in a food localisation task, but were still able to effectively navigate using sun compass information. However, their directional choices were significantly affected when the visual beacons were removed.

Summary: Magnetic field sensors are crucial for the control and physics exploitation of fusion devices. The new magnetic diagnostics in COMPASS-U will operate in high temperature environments. Different sensor types require precise calibration to ensure their dynamic range and bandwidth meet the requirements.

Summary: In this study, cue-conflict experiments were conducted on three European songbird species to investigate their calibration strategies in compass systems. The results showed that only adult robins displayed signs of calibration, while the other species did not, even when they had access to celestial cues. Based on these findings, it is suggested that there is no uniform theory to explain birds' calibration strategies and it may vary among species or populations.

Summary: Sensitivity to the earth's magnetic field is a widely present and intriguing sensory system in animals. Research on amphibians has provided valuable insights into the functional properties of magnetoreception, including the presence of a light-dependent magnetic compass and a non-light-dependent mechanism involving magnetite and/or maghemite particles. Short-range homing relying on a magnetic map places higher demands on sensory detection, processing, and memory mechanisms compared to long-distance migration.
