New open-source method to improve decoding of single-cell data      (via sciencedaily.com)     Original source 

Researchers have developed a new open-source computational method, dubbed Spectra, which improves the analysis of single-cell transcriptomic data. By guiding data analysis in a unique way, Spectra can offer new insights into the complex interplay between cells — like the interactions between cancer cells and immune cells, which are critical to improving immunotherapy treatments.

Survival of the newest: the mammals that survive mass extinctions aren't as 'boring' as scientists thought      (via sciencedaily.com)     Original source 

For decades, scientists have assumed that mammals and their relatives that survived challenging times (like those during mass extinctions) made it because they were generalists that were able to eat just about anything and adapt to whatever life threw at them. A new study into the mammal family tree through multiple mass extinctions revealed that the species that survived aren't as generic as scientists had thought: instead, having new and different traits can be the key to succeeding in the aftermath of a catastrophe.

Proteins roll the dice to determine bee sex      (via sciencedaily.com)     Original source 

To date it has been unclear exactly how the sex of a bee is determined. A research team comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. They describe how this process is similar to a game involving two dice.

A hygiene program for chromosomes      (via sciencedaily.com)     Original source 

Researchers identified and characterized a new cellular compartment in vertebrate cells that might be a precursor of today's eucaryotic nucleus. The study reveals that mammalian cells recognize, cluster, sort and keep extrachromosomal DNA -- like transfected plasmid DNA and endogenous circular DNAs originating from telomeres of the chromosome -- away from chromosomal DNA. That suggests that there is a cell autonomous genome defense system.

Small but mighty new gene editor      (via sciencedaily.com)     Original source 

A new CRISPR-based gene-editing tool has been developed which could lead to better treatments for patients with genetic disorders. The tool is an enzyme, AsCas12f, which has been modified to offer the same effectiveness but at one-third the size of the Cas9 enzyme commonly used for gene editing. The compact size means that more of it can be packed into carrier viruses and delivered into living cells, making it more efficient.

A lethal parasite's secret weapon: Infecting non-immune cells      (via sciencedaily.com)     Original source 

The organisms that cause visceral leishmaniasis, a potentially deadly version of the parasitic disease that most often affects the skin to cause disfiguring disease, appear to have a secret weapon, new research suggests: They can infect non-immune cells and persist in those uncommon environments.

An advance in cryo-EM could be a significant boon for research on potential cancer therapies      (via sciencedaily.com)     Original source 

A technology called cryo-electron microscopy enables scientists to see the atomic structure of biological molecules in high resolution. But to date, it has been ineffective for imaging small molecules. A team of biochemists devised a solution that makes it possible to hold small protein molecules in place while they're being imaged, which will enable cryo-EM to produce much clearer images of such molecules. The advance is significant because small and medium-sized protein molecules are an area of focus in research on potential new drugs for cancer and other diseases.
