Methods for substituting onsite ambient ultraviolet radiation measurements for personal exposure studies

Photochemistry and Photobiology, EarlyView.
Three methods for substituting on‐site ambient ultraviolet radiation measurements for personal exposure measurements were investigated. Assuming spatial persistency of measurements from high‐grade instruments delivers lowest uncertainties up to distances of 82 km.

Education and Understanding of Astronomy through Total Solar Eclipses

, 2003
A total solar eclipse has a great impact on ppeople, and hence there are very old historic records in China, Mesopotamia, etc. The impact still does not change in present times, and inspires wonder in us. The spectacular and magnificent event at a total

Probing the molecular determinants of emission enhancement in RNA aptamer–metal complex systems

Photochemistry and Photobiology, EarlyView.
Light up aptamer: fluorophore pairs are widely used in sensing and imaging, with coordination complex fluorophores providing specific benefits due to their long‐lived emission. Here, we examined key structural and electronic features of these metal complexes to identify the requirements for productive engagement with an RNA aptamer.

Effects of 1 Gray radiation on the biophysical properties of the tibia and femur from hindlimb‐suspended rats

Experimental Physiology, EarlyView.
Abstract Long‐term space travel (e.g. travel to Mars) will greatly exceed the recommended lifetime radiation dose of 600 millisieverts (mSv) and have a detrimental effect on skeletal fragility. Our objective was to determine if 1 Gray (GY) radiation impacts the biomechanical properties of the tibia and femur from rats under microgravity.

A Path to Better Science Through Co‐Creation and Open Infrastructure

Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract Proprietary development solutions are often perceived as being delivered more quickly and easily than open methods, fueling the misconception that they inherently produce better overall outcomes. However, we argue that open development practices can lead to both efficient and maximally impactful outcomes.
