Study shows erosion of ozone layer responsible for mass extinction event
Researchers at the University of Southampton have shown that an extinction event 360 million years ago, that killed much of the Earth's plant and freshwater aquatic life, was caused by a brief breakdown of the ozone layer that shields the Earth from damaging ultraviolet (UV) radiation. This is a newly discovered extinction mechanism with profound implications for our warming world today.

A quantitative description of these examples of "order-by-disorder" phenomena has remained elusive in nearly ferromagnetic metals and…

Putative regulators for the continuum of erythroid differentiation revealed by single-cell transcriptome of human BM and UCB cells [Developmental Biology]
Fine-resolution differentiation trajectories of adult human hematopoietic stem cells (HSCs) involved in the generation of red cells is critical for understanding dynamic developmental changes that accompany human erythropoiesis. Using single-cell RNA sequencing (scRNA-seq) of primary human terminal erythroid cells (CD34−CD235a+) isolated directly from adult bone marrow (BM) and umbilical cord…

Collective effects of XMAP215, EB1, CLASP2, and MCAK lead to robust microtubule treadmilling [Biophysics and Computational Biology]
Microtubule network remodeling is essential for fundamental cellular processes including cell division, differentiation, and motility. Microtubules are active biological polymers whose ends stochastically and independently switch between phases of growth and shrinkage. Microtubule treadmilling, in which the microtubule plus end grows while the minus end shrinks, is observed in cells;…

Imperfect transparency and camouflage in glass frogs [Ecology]
Camouflage patterns prevent detection and/or recognition by matching the background, disrupting edges, or mimicking particular background features. In variable habitats, however, a single pattern cannot match all available sites all of the time, and efficacy may therefore be reduced. Active color change provides an alternative where coloration can be altered…

Algal neurotoxin biosynthesis repurposes the terpene cyclase structural fold into an N-prenyltransferase [Biochemistry]
Prenylation is a common biological reaction in all domains of life wherein prenyl diphosphate donors transfer prenyl groups onto small molecules as well as large proteins. The enzymes that catalyze these reactions are structurally distinct from ubiquitous terpene cyclases that, instead, assemble terpenes via intramolecular rearrangements of a single substrate….

Neural representations of perceptual color experience in the human ventral visual pathway [Psychological and Cognitive Sciences]
Color is a perceptual construct that arises from neural processing in hierarchically organized cortical visual areas. Previous research, however, often failed to distinguish between neural responses driven by stimulus chromaticity versus perceptual color experience. An unsolved question is whether the neural responses at each stage of cortical processing represent a…

A methyl-TROSY approach for NMR studies of high-molecular-weight DNA with application to the nucleosome core particle [Biophysics and Computational Biology]
The development of methyl-transverse relaxation-optimized spectroscopy (methyl-TROSY)–based NMR methods, in concert with robust strategies for incorporation of methyl-group probes of structure and dynamics into the protein of interest, has facilitated quantitative studies of high-molecular-weight protein complexes. Here we develop a one-pot in vitro reaction for producing NMR quantities of methyl-

Spatial frequency tuning of motor responses reveals differential contribution of dorsal and ventral systems to action comprehension [Psychological and Cognitive Sciences]
Understanding object-directed actions performed by others is central to everyday life. This ability is thought to rely on the interaction between the dorsal action observation network (AON) and a ventral object recognition pathway. On this view, the AON would encode action kinematics, and the ventral pathway, the most likely intention…

Load-induced dynamical transitions at graphene interfaces [Applied Physical Sciences]
The structural superlubricity (SSL), a state of near-zero friction between two contacted solid surfaces, has been attracting rapidly increasing research interest since it was realized in microscale graphite in 2012. An obvious question concerns the implications of SSL for micro- and nanoscale devices such as actuators. The simplest actuators are…

Superdiffusive transport of energy in one-dimensional metals [Physics]
Metals in one spatial dimension are described at the lowest energy scales by the Luttinger liquid theory. It is well understood that this free theory, and even interacting integrable models, can support ballistic transport of conserved quantities including energy. In contrast, realistic one-dimensional metals, even without disorder, contain integrability-breaking interactions…

Membrane-tethered mucin-like polypeptides sterically inhibit binding and slow fusion kinetics of influenza A virus [Biophysics and Computational Biology]
The mechanism(s) by which cell-tethered mucins modulate infection by influenza A viruses (IAVs) remain an open question. Mucins form both a protective barrier that can block virus binding and recruit IAVs to bind cells via the sialic acids of cell-tethered mucins. To elucidate the molecular role of mucins in flu…

In vivo mapping of a GPCR interactome using knockin mice [Pharmacology]
With over 30% of current medications targeting this family of proteins, G-protein–coupled receptors (GPCRs) remain invaluable therapeutic targets. However, due to their unique physicochemical properties, their low abundance, and the lack of highly specific antibodies, GPCRs are still challenging to study in vivo. To overcome these limitations, we combined here…
