Incorporation of Chiral Frustrated Lewis Pair into Metal–Organic Framework with Tailored Microenvironment for Heterogeneous Enantio- and Chemoselective Hydrogenation (open access)

Incorporation of Chiral Frustrated Lewis Pair into Metal–Organic Framework with Tailored Microenvironment for Heterogeneous Enantio- and Chemoselective Hydrogenation

Article states that the development of efficient heterogeneous catalysts with multiselectivity (e.g., enantio- and chemoselectivity) has long been sought after but with limited progress being made so far. To achieve enantio- and chemoselectivity in a heterogeneous system, as inspired by enzymes, the authors illustrate herein an approach of creating an enzyme-mimic region (EMR) within the nanospace of a metal–organic framework (MOF) as exemplified in the context of incorporating a chiral frustrated Lewis pair (CFLP) into a MOF with a tailored pore environment.

Whole-genome survey reveals extensive variation in genetic diversity and inbreeding levels among peregrine falcon subspecies (open access)

Whole-genome survey reveals extensive variation in genetic diversity and inbreeding levels among peregrine falcon subspecies

Article describes how, in efforts to prevent extinction, resource managers are often tasked with increasing genetic diversity in a population of concern to prevent inbreeding depression or improve adaptive potential in a changing environment. The authors used whole-genome resequencing to generate over two million single nucleotide polymorphisms (SNPs) from multiple individuals of all peregrine falcon subspecies.

DNA metabarcoding captures different macroinvertebrate biodiversity than morphological identification approaches across a continental scale

Article describes how DNA-based aquatic biomonitoring methods show promise to provide rapid, standardized, and efficient biodiversity assessment to supplement and in some cases replace current morphology-based approaches that are often less efficient and can produce inconsistent results. The authors present a comparison of DNA metabarcoding and morphological identification, leveraging national-scale, open-source, ecological datasets from the National Ecological Observatory Network.

Manipulating microRNA miR408 enhances both biomass yield and saccharification efficiency in poplar (open access)

Manipulating microRNA miR408 enhances both biomass yield and saccharification efficiency in poplar

Article describes how the conversion of lignocellulosic feedstocks to fermentable sugar for biofuel production is inefficient, and most strategies to enhance efficiency directly target lignin biosynthesis, with associated negative growth impacts. The authors demonstrate, for both laboratory-and field-grown plants, that expression of Pag-miR408 in poplar significantly enhances saccharification, with no requirement for acid-pretreatment, while promoting plant growth.

Complexity synchronization: a measure of interaction between the brain, heart and lungs

Authors of the article address the measurable consequences of the network effect (NE) on time series generated by different parts of the brain, heart, and lung organ-networks (ONs), which are directly related to their inter-network and intra-network interactions. The authors assert that these same physiologic ONs have been shown to generate crucial event (CE) time series, and herein are shown ,using modified diffusion entropy analysis (MDEA) to have scaling indices with quasiperiodic changes in complexity, as measured by scaling indices, over time.

Finding new friends and revisiting old ones – how plant lipid droplets connect with other subcellular structures

Article talks about how the number of described contact sites between different subcellular compartments and structures in eukaryotic cells has increased dramatically in recent years, which has substantially reinforced the well-known premise that these kinds of connections are essential for overall cellular organization. The authors discuss contact sites involving plant lipid droplets (LDs), including LD-endoplasmic reticulum (ER) connections that mediate the biogenesis of new LDs at the ER, LD-peroxisome connections.

Mediterranean Spur-Thighed Tortoises (Testudo graeca) Have Optimal Speeds at Which They Can Minimise the Metabolic Cost of Transport, on a Treadmill

Article experimentally quantifies the metabolic cost of transport in Mediterranean spur-thighed tortoises walking on a treadmill while also quantifying the kinematics of their movement. Results found that tortoises move more efficiently than predicted and presents the first data demonstrating a curvilinear cost of transport over their speed range. The authors conclude that tortoises have an optimum speed at which they move to minimise their metabolic cost of locomotion.
