The Extinction and De-Extinction of Species

open access: yesPhilosophy & Technology, 2016
In this paper, we discuss the following four alternative ways of understanding the outcomes of resurrection biology (also known as de-extinction). Implications of each of the ways are discussed with respect to concepts of species and extinction. (1) Replication: animals created by resurrection biology do not belong to the original species but are ...

Selective Growth of Bulk‐Like Perovskite in Plasmonic Nanoholes for Enhanced Two‐Photon‐Excited Emission

open access: yesAdvanced Materials, EarlyView.
Vacuum‐assisted capillary infiltration delivers perovskite precursors deep into gold nanohole plasmonic hotspots, enabling uniform in situ crystallization of bulk‐like CsPbBr3 within confined cavities. Verified by peel‐off and structural analyses, the hybrid platform shows simulated |E/E₀| ≈2.80 at 800 nm and ∼40‐fold two‐photon absorption‐enhanced ...

Methanolic extract of Morinda citrifolia L. (noni) unripe fruit attenuates ethanol-induced conditioned place preferences in mice

open access: yesFrontiers in Pharmacology, 2016
Phytotherapy is an emerging field successfully utilized to treat various chronic diseases including alcohol dependence. In the present study, we examined the effect of the standardized methanolic extract of Morinda citrifolia Linn. unripe fruit (MMC), on

From Behavior to Dynamics: Decoding Carrier Roles in Cu‐based Photocathodes for Solar‐Driven CO2 Reduction

open access: yesAdvanced Materials, EarlyView.
The performance of Cu‐based photocathodes in photoelectrochemical CO2 reduction is not governed by catalytic sites alone, but by the dynamic journey of photogenerated carriers. This review decodes how carrier generation, recombination, transport, accumulation, extraction, and electrolyte coupling shape catalytic activity, selectivity, and stability ...

The Rise of the Anthroposphere since 50,000 Years: An Ecological Replacement of Megaherbivores by Humans in Terrestrial Ecosystems?

open access: yesFrontiers in Ecology and Evolution, 2018
Megaherbivores fulfilled a number of important ecological functions in terrestrial ecosystems and behaved as ecological engineers since 300 million years until around 12,000 years ago. These essential ecological functions include opening vegetation cover,

Ligand Engineering for Precise Control of Ultrathin CsPbI3 Nanoplatelet Superlattices for Efficient Light‐Emitting Diodes

open access: yesAdvanced Materials, EarlyView.
In this work, we introduce ancillary‐ligand‐mediated growth control of ultrathin CsPbI3 PeNPLs to achieve highly uniform thickness and reduced agglomeration. Strong ancillary‐ligand coordination to the perovskite surface regulates nucleation and improves surface passivation, enabling color‐pure emission and preferentially oriented superlattices.

Studying multisensory processing and its role in the representation of space through pathological and physiological crossmodal extinction

open access: yesFrontiers in Psychology, 2011
The study of crossmodal extinction has brought a considerable contribution to our understanding of how the integration of stimuli perceived in multiple sensory modalities is used by the nervous system to build coherent representations of the space that ...

Mass extinctions [PDF]

open access: yesCurrent Biology, 2005
Factors influencing the evolution of complex traits such as body size are notoriously difficult to study but a new review of work on marine iguanas in the Galapagos islands suggests an answer may lie in the interplay of natural and sexual selection.

Giant Anisotropy and High Second‐Order Nonlinearity of 3R‐MoS2 for Multifunctional Photonics

open access: yesAdvanced Materials, EarlyView.
Graphical abstract highlights, 3R‐polytype of MoS2 (3R‐MoS2) as a multifunctional photonic platform enabled by giant optical anisotropy and optical nonlinearities, demonstrating subdiffractional waveguiding, giant second‐harmonic (SH) generation, and high‐performance reflective polarization control.
