Seeing Through an Ant's Eyes: Do Entomopathogenic Fungi Extend Their Cognition to Their Hosts?

open access: yesTopics in Cognitive Science, EarlyView.
Abstract Post‐cognitivist approaches recognize cognition as a phenomenon that involves not just brains but all the sensorimotor apparatus of organisms. This means that brains are not always required for the emergence of cognition and that every organism can, in principle, be cognitive, unlocking a theoretical framework to explain the complex adaptive ...

Finding Fireballs in Lightning: A Daily Pipeline to Find Meteors in Weather Satellite Data

open access: yesEarth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Weather satellite data contains a wealth of information well beyond its application to meteorology. The GOES weather satellite Geostationary Lightning Mapper instruments detect millions of lightning strikes per day. Within these “haystacks” of lightning are a handful of “needles” of bolides (aka bright fireballs, or exploding meteors). We have

Parallax

open access: yes, 2013
For the uninitiated, parallax is a fancy term for triangulation, which we humans naturally do in the form of depth perception – your eyes are separated by a small distance from each other so they see slightly different views of the world. You can try it now by closing one eye, holding out your thumb, and lining it up with a mark on a far wall, then ...

Spectroscopic magnitudes and parallaxes of A-typestars.

open access: yes, 1926
The spectroscopic absolute magnitudes and parallaxes of 200 A stars have been determined. The material used was the large collection of 1-prism slit spectrograms of the Yerkes Observatory.

Parallaxes and Distance Estimates for 14 Cataclysmic Variable Stars

open access: yes, 2003
I used the 2.4 m Hiltner Telescope at MDM Observatory in an attempt to measure trigonometric parallaxes for 14 cataclysmic variable stars. Techniques are described in detail.

Application of Deep Learning and Explainable AI to NIR Auroral Detection in Satellite Time‐Series Images

open access: yesSpace Weather, Volume 24, Issue 7, July 2026.
Abstract In this study, we employ a deep learning approach to detect auroras from near‐infrared (NIR) sequential images captured by the satellite‐based imager, the Enhanced Polar Outflow Probe (e‐POP)/Fast Auroral Imager (FAI). We also apply the Eigen‐Class Activation Map (Eigen‐CAM), an explainable AI technique in a broad sense, as a post‐hoc ...

The Lutz-Kelker bias in trigonometric parallaxes

open access: yes, 1997
The theoretical prediction that trigonometric parallaxes suffer from a statistical effect, has become topical again now that the results of the Hipparcos satellite have become available.

Trigonometric parallaxes of ten ultracool subdwarfs

open access: yes, 2008
Aims. We measure absolute trigonometric parallaxes and proper motions with respect to many background galaxies for a sample of ten ultracool subdwarfs. Methods.

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics

open access: yesMarine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...
