The exceptional preservation of Aix-en-Provence spider fossils could have been facilitated by diatoms

Communications Earth & Environment, 2022
Extracellular polymeric substances produced by lacustrine diatoms helped promote sulfurization and the exceptional preservation of arachnids in the Oligocene age Aix-en-Provence Formation, France, according to optical and electron microscopic analyses.

Computed tomography sheds new light on the affinities of the enigmatic euarthropod Jianshania furcatus from the early Cambrian Chengjiang biota

BMC Evolutionary Biology, 2020
Background The Chengjiang biota is one of the most species-rich Cambrian Konservat-Lagerstätten, and preserves a community dominated by non-biomineralized euarthropods. However, several Chengjiang euarthropods have an unfamiliar morphology, are extremely

Deciphering the preservation of fossil insects: a case study from the Crato Member, Early Cretaceous of Brazil [PDF]

PeerJ, 2016
Exceptionally well-preserved three-dimensional insects with fine details and even labile tissues are ubiquitous in the Crato Member Konservat Lagerstätte (northeastern Brazil). Here we investigate the preservational pathways which yielded such specimens.

Deep water vetulicolians from the lower Cambrian of China [PDF]

PeerJ
Vetulicolians are an enigmatic phylum of extinct Cambrian marine invertebrates. They are particularly diverse in the Chengjiang Biota of China, but representatives have been recovered from other Fossil-Lagerstätten (Cambrian Stage 3-Drumian).

Open exceptional strings and D-branes

Journal of High Energy Physics, 2019
We study D-branes in the extended geometry appearing in exceptional field theory (or exceptional generalised geometry). Starting from the exceptional sigma model (an E d(d) covariant worldsheet action with extra target space coordinates), we define open ...

Retrospective Analysis of Donor Lymphocyte Infusions in Pediatric Patients With Mixed Chimerism After Hematopoietic Stem Cell Transplantation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Allogeneic hematopoietic stem cell transplantation (alloHSCT) is an essential therapy for several malignant and nonmalignant diseases, but relapse and graft loss remain the principal threats to its success. Routine monitoring of chimerism and minimal residual disease (MRD) enables early detection of imminent recurrence and guides ...
