Physiological fidelity of a satellite-derived forest resilience indicator in the Amazon
Abstract Reliable resilience indicators are urgently needed to monitor global forest health under increasing climate stress. Lag-1 temporal autocorrelation (TAC) of satellite vegetation indices captures forest recovery speed and is widely used as a resilience metric, but its mechanistic underpinnings and methodological reliability have been questioned.

A prototype differential atom interferometer for fundamental physics
|
Abstract Gravitational waves and ultralight dark matter are among the most compelling frontiers in fundamental physics, motivating proposals for very-long-baseline atom interferometerssuch as AION1, MAGIS2, AICE3 and AEDGE4 that aim to detect at frequencies at which ground-based5 and space-borne6 laser interferometers lose sensitivity.

New insights on angiosperm crown age based on Bayesian node dating and skyline fossilized birth-death approaches - Nature Communications
Abstract Despite considerable work in recent years, pinpointing the time when angiosperms originated has been challenging. However, the rapid development of molecular clock methodology has provided new tools to resolve this conundrum. In particular, the fossilized birth-death model establishes a rich interplay between molecules and stratigraphy by incorporating fossils explicitly into dating analyses.
Elevated human impact on islands increases the introduction and extinction status of native insular reptiles
Introduction In the Anthropocene, humans have altered species ranges and reassembled global biogeographic patterns that arose naturally across eons of evolution (Alroy 2015, Capinha et al. 2015, Ceballos et al. 2017). Range contraction and expansion varies across species due to human impact (Pacifici et al. 2020).
Measurement of the sodium and iodine scintillation quenching factors across multiple NaI(Tl) detectors to identify systematics
The amount of light produced by nuclear recoils in scintillating targets is strongly quenched compared to that produced by electrons. A precise understanding of the quenching factor is particularly interesting for weakly interacting massive particles (WIMP) searches and coherent elastic neutrino-nucleus scattering (CEνNS) measurements since both rely on nuclear recoils, whereas energy calibrations are more readily accessible from electron recoils.
Elevated human impact on islands increases the introduction and extinction status of native insular reptiles
Abstract Species ranges are changing in the Anthropocene, the ranges of introduced species are expanding, while extinction-prone species are contracting. Introductions and extinctions are both caused by how species respond to human impacts, but it is unknown why the ranges of some species expand and some contract.
Ongoing declines for the world’s amphibians in the face of emerging threats - Nature
|
Abstract Systematic assessments of species extinction risk at regular intervals are necessary for informing conservation action1,2. Ongoing developments in taxonomy, threatening processes and research further underscore the need for reassessment3,4. Here we report the findings of the second Global Amphibian Assessment, evaluating 8,011 species for the International Union for Conservation of Nature Red List of Threatened Species.

The colonisation of Madagascar by land‐bound vertebrates
ABSTRACT Despite discussions extending back almost 160 years, the means by which Madagascar's iconic land vertebrates arrived on the island remains the focus of active debate. Three options have been considered: vicariance, range expansion across land bridges, and dispersal over water. The first assumes that a group (clade/lineage) occupied the island when it was connected with the other Gondwana landmasses in the Mesozoic.
Haiti’s biodiversity threatened by nearly complete loss of primary forest
Significance The loss of forest from human activities is a global threat to biodiversity, continually diminishing populations of forest-dwelling species. However, species extinction usually is delayed until the last habitats disappear. Nonetheless, mass extinction may be imminent in a small number of tropical countries with low forest cover. Here, we find that Haiti has less than 1% of its original primary forest and is therefore among the most deforested countries in the world.
Haiti’s biodiversity threatened by nearly complete loss of primary forest
Human-robot interaction researchers are developing robot teammates for humans working in a range of settings, from manufacturing floors to outer space. These robots are designed to collaborate with humans directly. But designing a good teammate isn’t easy.
