Minimum capture-recapture rates and years of banding station operations to obtain reliable adult annual survival estimates

Journal of Field Ornithology, 2022
We examined variability in adult annual survival rate estimates for 33 breeding bird species, using 2011–2019 data from a 38-station Monitoring Avian Productivity and Survivorship (MAPS) program in Alberta, Canada.

Lunar Laser Ranging Retroreflectors: Velocity Aberration and Diffraction Pattern

The Planetary Science Journal, 2023
The Lunar Laser Ranging (LLR) retroreflector arrays have been on the Moon for half a century. During that time, the laser range uncertainty has improved by a factor of 100. Consequently, the science results have also improved by orders of magnitude.

How the moon formed - new research [PDF]

, 2020
First paragraph: How the Earth got its moon is a long debated question. The giant impact theory – which states that the Moon formed from the a collision between the early Earth and a rocky body called Theia – has become the front runner among the ...

Mass spectrometry based identification of AMP‐O‐Tris generated by Thermococcus onnurineus Cas10

FEBS Open Bio, EarlyView.
Isolated Thermococcus onnurineus Cas10 generates the noncanonical ATP‐derived product AMP‐O‐Tris while in Tris‐containing buffer as identified via mass spectrometry, revealing relaxed nucleophile selectivity under isolated conditions. These findings suggest that multiprotein Csm complex assembly restricts Cas10 reactivity toward canonical cyclic ...
