Mars Exploration Rovers: 4 Years on Mars [PDF]

, 2008
This January, the Mars Exploration Rovers "Spirit" and "Opportunity" are starting their fifth year of exploring the surface of Mars, well over ten times their nominal 90-day design lifetime.

Evidence for life in the isotopic analysis of surface sulphates in the Haughton impact structure, and potential applications on Mars [PDF]

, 2012
The analysis of sulphur isotopic compositions in three sets of surface sulphate samples from the soil zone in the Haughton impact structure shows that they are distinct.

A systematic review identifying fitness metrics indicative of simulated astronaut extravehicular activity task performance

npj Microgravity
To prepare for safe and successful completion of surface operations during future missions to the Moon and Mars, understanding the relationships between fitness and simulated extravehicular activity (EVA) performance is imperative. This systematic review

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

Molecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Cancer‐associated mutations in endometriosis reframe a benign disease through molecular oncology

Molecular Oncology, EarlyView.
This review aims to comprehensively analyse cancer‐associated somatic mutations (CAMs) present in endometriotic lesions, emphasizing their biological roles, spatial distribution and implications for translational applications in medicine. By contextualizing a benign state within a genomic framework, this analysis seeks to establish its value as a ...

Perspectives for Crewed Missions to Mars: Exploration from Orbit and/or Short Stay

The debate “humans versus robots”, on Mars or anywhere else will not be engaged here. The decision has been made—by a single entity, a coalition, or a wide international agreement—to send astronauts to Mars.

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

Molecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

Molecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

Review of boundary model studies in the Venusian and Martian induced magnetosphere

地球与行星物理论评
Although Venus and Mars do not have a global magnetic field but have atmospheres and ionospheres. During their coupling with the solar wind, the induced magnetospheres are created, as well as the boundaries of the bow shock and the magnetic pileup ...
