Protein language models (PLMs) have demonstrated impressive success in modeling proteins. However, general-purpose "foundational" PLMs have limited performance in modeling antibodies due to the latter's hypervariable regions, which do not conform to the evolutionary conservation principles that such models rely on. In this study, we propose a transfer learning framework called Antibody Mutagenesis-Augmented Processing (AbMAP), which fine-tunes foundational models for antibody-sequence inputs by supervising on antibody structure and binding specificity examples.

Odours released by objects in natural environments can contain information about their spatial locations. In particular, the correlation of odour concentration timeseries produced by two spatially separated sources contains information about the distance between the sources. For example, mice are able to distinguish correlated and anti-correlated odour fluctuations at frequencies up to 40 Hz, while insect olfactory receptor neurons can resolve fluctuations exceeding 100 Hz.

Measuring virus in biofluids is complicated by confounding biomolecules coisolated with viral nucleic acids. To address this, we developed an affinity-based microfluidic device for specific capture of intact severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Our approach used an engineered angiotensin-converting enzyme 2 to capture intact virus from plasma and other complex biofluids.

The purpose of this study is to provide an in-depth examination of the complex aspects of hereditary and pathological conditions arising based on psychogenetic factors, in particular, the disclosure of elements that determine the causes of their appearance. The following methods were used in the study: analytical, typological approaches, and generalization. It was found that genetic inheritance plays a significant role in the occurrence of autism spectrum disorders, bipolar disorder, schizophrenia, and other pathologies.

Molecular beacon (MB) probes have been extensively used for nucleic acid analysis. However, MB probes fail to hybridize with folded DNA or RNA. Here, we demonstrate that MB probes equipped with extra sequences complementary to the analyte, named 'tail', can increase the signal-to-background ratio by ∼40-fold and hybridization rates by ∼800-fold compared to conventional MB probes.
