An Australian snake catcher responded to a home where a mother found a deadly snake wrapped around her child's Lego play set.

In situ architecture, function, and evolution of a contractile injection system

6 hours ago from Science NOW

Contractile injection systems mediate bacterial cell-cell interactions by a bacteriophage tail–like structure. In contrast to extracellular systems, the type 6 secretion system (T6SS) is defined by intracellular localization and attachment...

Deriving genomic diagnoses without revealing patient genomes

6 hours ago from Science NOW

Patient genomes are interpretable only in the context of other genomes; however, genome sharing enables discrimination. Thousands of monogenic diseases have yielded definitive genomic diagnoses and potential gene therapy targets....

Comprehensive single-cell transcriptional profiling of a multicellular organism

6 hours ago from Science NOW

To resolve cellular heterogeneity, we developed a combinatorial indexing strategy to profile the transcriptomes of single cells or nuclei, termed sci-RNA-seq (single-cell combinatorial indexing RNA sequencing). We applied sci-RNA-seq to...

Viruses and Aphids That Help Crops? Scientists Think It May Be Possible

6 hours ago from Newswise - Scinews

Iowa State University scientists are contributing to a multi-institutional effort to help corn stand up to stress brought on by drought and disease by using viruses and aphids to activate...

Worm atlas profiles gene readouts in every cell type in the animal

6 hours ago from Physorg

The roundworm stars in the first-ever compilation of gene readouts in every kind of cell in an animal. The readouts, which were taken at a particular stage in the worm's...

Male fruit flies can smell a good mate based on her metabolism

6 hours ago from Physorg

A female fruit fly must balance her energy usage between making eggs now and storing nutrients for later. This balance affects the pheromones that she produces and impacts whether male...
