Discovery of a Bow-shock Nebula Around the Z Cam-type Cataclysmic Variable SY Cancri

The Astronomical Journal
We report the serendipitous discovery of a bow-shock nebula around the cataclysmic variable (CV) SY Cancri. In addition, SY Cnc lies near the edge of a faint H α -emitting nebula with a diameter of about $15^{\prime} $ .

Gas distribution, kinematics and star formation in faint dwarf galaxies [PDF]

, 2005
We compare the gas distribution, kinematics and the current star formation in a sample of 10 very faint (-13.37 < M_B < -9.55) dwarf galaxies. For 5 of these galaxies we present fresh, high sensitivity, GMRT HI 21cm observations.

Drivers of Hirola Antelope Diet Selection in Natural and Managed Habitat in Eastern Kenya

Ecology and Evolution, Volume 16, Issue 1, January 2026.
Hirola (Beatragus hunteri) populations in eastern Kenya consumed 17 forage species, favoring the grass Chloris virgata and the forbs Commelina benghalensis and C. diffusa. Nutrient analyses showed that natural habitats offered higher phosphorus, magnesium, and digestibility, whereas managed sites provided more sodium, potassium, and crude protein, with

Ballistics and wound ballistics of CO2‐powered dart guns in relation to ungulate dart injury and animal welfare

Wildlife Biology, Volume 2026, Issue 1, January 2026.
Large mammals are darted with dart guns to inject drugs or to collect biopsy tissue for capture, research, or veterinary purposes, especially for procedures involving wild and zoo animals. Darting is invasive and associated with risks of trauma, and severe and fatal dart injuries have been reported.

Recent science results with the two-telescope IOTA [PDF]

, 2002
The IOTA (Infrared Optical Telescope Array) has been routinely operating with two-telescopes since 1994, a mode destined to become obsolete following its recent conversion to a three-telescope array.

Airborne DNA and Spider Webs Outperform Other eDNA Sources for Monitoring Terrestrial Vertebrates

Molecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Understanding the strengths and limitations of different environmental DNA substrates is essential for optimising terrestrial vertebrate surveys and monitoring. However, the performance of newly explored substrates (airborne eDNA, vegetation swabs, spiderwebs) compared to longstanding eDNA sources (water and soil) is uncertain.

Livelihood and Season Determine Human‐Carnivore Conflict Around Zakouma National Park, Chad

African Journal of Ecology, Volume 64, Issue 1, January 2026.
ABSTRACT Transhumant pastoralists and their livestock spend the dry season in the floodplains around Zakouma National Park, Chad, where resident people practice mixed farming. We used interview data from 146 households to investigate the differences between these user groups in terms of vulnerability to depredation, attitudes and impact on conservation.

Three editions of the Star Catalogue of Tycho Brahe

, 2010
Tycho Brahe completed his catalogue with the positions and magnitudes of 1004 fixed stars in 1598. This catalogue circulated in manuscript form. Brahe edited a shorter version with 777 stars, printed in 1602, and Kepler edited the full catalogue of 1004 ...

Nova-like Cataclysmic Variables in the Infrared [PDF]

, 2014
Novalike cataclysmic variables have persistently high mass transfer rates and prominent steady state accretion disks. We present an analysis of infrared observations of twelve novalikes obtained from the Two Micron All Sky Survey, the Spitzer Space ...

Increasing Targeted Poaching of Lions for Trade Has the Potential to Pose an Existential Threat to the Species in Africa

Conservation Letters, Volume 19, Issue 1, January/February 2026.
ABSTRACT Lions (Panthera leo) in Africa are targeted for the illegal wildlife trade, driven by demand in African and Asian markets, for their body parts. This threat is distinct from traditional drivers of lion decline such as prey depletion, habitat loss, and persecution and is poorly understood, underreported, growing, and prone to the influence of ...
