Multi‐scale maternal behavioral responses by white‐tailed deer to coyote predation risk

The Journal of Wildlife Management, Volume 90, Issue 1, January 2026.
In the piedmont region of the southeastern US, white‐tailed deer adjust maternal care strategies in response to variation in risk of encountering coyotes. In areas frequented by coyotes, adult female deer (i.e., does) increase their use of space, likely to avoid drawing coyotes to the location where a fawn is hidden.

The AO327 Drift Survey Catalog and Data Release of Pulsar Detections

The Astrophysical Journal Supplement Series
The AO327 drift survey for radio pulsars and transients used the Arecibo telescope from 2010 until its collapse in 2020. AO327 collected ∼3100 hr of data at 327 MHz with a time resolution of 82 μ s and a frequency resolution of 24 kHz.

Cherenkov Telescope Array Observatory: Die Zukunft der Gammaastronomie

Physik in unserer Zeit, Volume 57, Issue 1, Page 10-18, January 2026.
Im Jahr 1989 hat das Wipple‐Observatorium die erste Quelle hochenergetischer Gammastrahlung entdeckt. 2002 waren dann sechs Quellen bekannt, 2024 schon mehr als 300. Und das ist immer noch lediglich die Spitze des Eisbergs in der jungen Geschichte der Gammaastronomie.

Nature of Ultralong Period Radio Transients: Could They Be Strange Dwarf Pulsars?

The Astrophysical Journal
Ultralong period radio transients (ULPTs), with periods of thousands of seconds, challenge conventional pulsar models. We propose that these isolated sources are strange dwarf (SD) pulsars—compact objects with a strange quark matter core surrounded by a ...

The origin of radio pulsar polarization

Monthly Notices of the Royal Astronomical Society, 2017
Polarisation of radio pulsar profiles involves a number of poorly understood, intriguing phenomena, such as the existence of comparable amounts of orthogonal polarisation modes (OPMs), strong distortions of polarisation angle (PA) curves into shapes inconsistent with the rotating vector model (RVM), and the strong circular polarisation V which can be ...

NiCu/Al2O3 Bimetallic Catalysts for Reductive Amination of Polyether 230: Synergistic Effects of Alloy Formation and Amorphous Support Properties

Journal of Chemistry, Volume 2026, Issue 1, 2026.
The development of efficient and scalable catalysts for polyether amine (PEA) synthesis via reductive amination remains an enduring industrial challenge. In this study, bimetallic NiCu alloys supported on amorphous alumina were rationally designed for the amination of low‐molecular‐weight polyether (PPG‐230).

The Discovery of a 41 s Radio Pulsar PSR J0311+1402 with ASKAP

The Astrophysical Journal Letters
The emerging population of long-period radio transients (LPTs) shows both similarities and differences with normal pulsars. A key difference is that their radio emission is too bright to be powered solely by rotational energy.

Leveraging Compressed Sensing and Radiomics for Robust Feature Selection for Outcome Prediction in Personalized Ultra‐Fractionated Stereotactic Adaptive Radiotherapy

Advanced Intelligent Systems, Volume 7, Issue 12, December 2025.
A compressed sensing (CS)‐based feature selection method is proposed to select the most informative elements in the radiomic features extracted from medical images of personalized ultra‐fractionated stereotactic adaptive treatment. The CS‐based approach is able to simplify the feature selection process and enhance the accuracy and robustness of a ...

Translational Remodeling of the Synaptic Proteome During Aging

Aging Cell, Volume 24, Issue 12, December 2025.
Aging induces a decoupling of protein regulation between the soma and the synapse. In particular, transcripts coding for ribosomal proteins decrease and their corresponding proteins increase in the synapse while the opposite happens in the soma. At the same time, synapse‐specific regulation of splicing takes place.
