A Comparison of Juvenile and Adult Sunflower Sea Star Transcriptomic Responses to Challenge With Sea Star Wasting Disease Tissue Homogenates

Ecology and Evolution, Volume 16, Issue 9, September 2026.
Sunflower sea stars have been hard hit by sea star wasting disease (SSWD), losing over 5 billion individuals along their natural range from Alaska and Southern California. This work uses transcriptomics to investigate the immune response of adult and juvenile sunflower sea stars exposed to SSWD.

Diversity-based Heuristic Search for Multiple-asteroid Tours

2024 IEEE Aerospace Conference
An asteroid tour is a sequence of asteroid flybys performed by a spacecraft in a single mission. Visiting different types of asteroids would be of a great scientific return, but planning such type of mission is highly complex. This is because the combinatorial problem of selecting sequences of asteroids is coupled with optimal control problem of ...

Different Frontier, Same Legal Script? On the Course of Replicating Earth's Patterns in Space

The Modern Law Review, Volume 89, Issue 5, Page 723-759, September 2026.
As states and private actors expand their activities in outer space, the international legal framework governing this domain risks extending longstanding structures of global inequality beyond Earth. This article examines how international space law, shaped by a broader disciplinary pattern of reactive legal development, is poised to reproduce ...

The Great Cosmic Silence: What Does the Fermi Paradox Tell About the Future of Humanity?

Global Policy, Volume 17, Issue 4, Page 553-565, September 2026.
ABSTRACT This article examines how institutional time horizons shape the long‐term survival prospects of human technological civilisation. While research on global catastrophic and existential risks has expanded, the temporal structures of political‐economic institutions remain underexamined.

Oxygen isotope variability in the IIIAB iron meteorites and their relationship to main group pallasites

Meteoritics &Planetary Science, Volume 61, Issue 9, Page 2393-2405, September 2026.
Abstract The light element distribution in planetary cores and the processes driving core evolution in rocky planets are poorly understood. Magmatic iron meteorites are samples from the cores of ancient embryonic planetesimals and therefore provide a window into the processes governing core evolution. We performed high precision oxygen isotope analyses

Direct Detection of Hydrogen Reveals a New Macroscopic Crustal Water Reservoir on Early Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The next great leap in Martian exploration is the return of samples to Earth. Maximizing their scientific value requires non‐destructive analytical techniques for early three‐dimensional characterization. Neutron computed tomography (CT), highly sensitive to hydrogen, complements conventional X‐ray CT and enables the detection of hydrous ...

Negotiating in a Foreign Land: Understanding the Curious Interactions Between Intracellular Mitochondria and Internalized Nanoparticles

Advanced Materials Interfaces, Volume 13, Issue 16, 18 August 2026.
Therapeutic nano‐drug delivery systems interact with cellular mitochondria in a multitude of ways. While the complexity of such interactions disrupts the mitochondrial electron transport chain and increases reactive oxygen species production, thereby contributing to nanoparticle toxicity, they also present unique theranostic opportunities in diseases ...

A Deep Search for Venus Co-orbital Asteroids

, 2021
Venus has recently been discovered to share its orbit with a ring of dust. This circumsolar ring of dust was imaged independently by two spacecraft: HELIOS A/B [1] and STEREO A/B [2]. HELIOS was able to estimate the radial and latitudinal extent of the ring by flying through it, while STEREO imaged its structure from 1 AU. Earlier work by Pokorný &

The Search for water ice on Comets and Asteroids

, 2021
The presence of water is considered one of the key ingredients for the formation of life on Earth. Indeed, current theories as to the origin of the Earth’s oceans suggest that the water located there originated from both comets and asteroids, with the exact fractional contribution still under discussion.
