Basolateral amygdala dopamine signals behavioural salience across exploration and learning

Jessica Capece Marsico, Malika Askarova, Olga Sharma, Sangeetha Nandakumar et autres

ABSTRACT Animals must balance exploration with threat avoidance, yet how neuromodulatory signals shape information-seeking states remains unclear. Using fibre photometry recordings in the basolateral amygdala in freely moving mice, we show that dopamine release is selectively elevated during self-initiated exploratory actions, adapts …

Detection of Four Cold Jupiters through Combined Analyses of Radial Velocity and Astrometry Data*

Yiyun Wu, Guang-Yao Xiao, R. Paul Butler, Fabo Feng et autres

Abstract Cold Jupiters play a crucial role in planet formation and dynamical evolution. Since their initial discovery around 47 UMa, they have attracted significant interest; however, their formation mechanisms remain uncertain, underscoring the need to expand the known population. In this work, …

Two warm sub-Saturn mass planets identified from the TESS Full Frame Images

Felipe I. Rojas, Rafael Brahm, Andrés Jordán, Néstor Espinoza et autres

Context. Characterization of warm giants is crucial to constrain giant planet formation and evolution. Measuring the mass and radius of these planets, combined with their moderated irradiation, allows us to estimate their planetary bulk composition, which is a key quantity to comprehend …

Deforestation detection and oxygen impact analysis using satellite imagery

Voruganti Sreevani, Battula Sravani, Shaik Shameem, Tammineedi Naga Sai Tanusri et autres

Deforestation continues to advance as a serious environmental problem that has double implications of loss of biodiversity and climate change effects and reduces oxygen in the air. Forest destruction causes ecological ecosystem decline as well as poor air quality problems that require …

The high optical brightness of the BlueWalker 3 satellite

Sangeetha Nandakumar, Siegfried Eggl, J. Tregloan-Reed, Christian Adam et autres

Abstract Large constellations of bright artificial satellites in low Earth orbit pose significant challenges to ground-based astronomy 1 . Current orbiting constellation satellites have brightnesses between apparent magnitudes 4 and 6, whereas in the near-infrared Ks band, they can reach magnitude 2 …

TOI-677b: A Warm Jupiter (P = 11.2 days) on an Eccentric Orbit Transiting a Late F-type Star

D. Bayliss, Jon M. Jenkins, Brett Addison, R. Vanderspek et autres

We report the discovery of TOI-677 b, first identified as a candidate in light curves obtained within Sectors 9 and 10 of the Transiting Exoplanet Survey Satellite (TESS) mission and confirmed with radial velocities. TOI-677 b has a mass of The host …
