New Technique Modifies Single Cells To Create Genetic “Mosaic” Organs
A new technique has been developed that allows different genes to be “switched off” in individual cells within an organ to create a “mosaic” of genetically modified cells, which shed light on the origins of a rare genetic disorder.

Genetically Modified Silkworms Produce Spider Silk Six Times Tougher Than Kevlar
For the first time, researchers have genetically modified common silkworms to produce full-length spider silk proteins. Such proteins can be used to produce fibers that are six times tougher than the Kevlar fiber used in bulletproof vests.

Novel Virus Identified in the Deep
Scientists have discovered a new virus isolated from sediment brought up from a depth of 8,900 meters. The virus is a bacteriophage – a virus that infects and replicates inside bacteria – and is thought to be the deepest known isolated phage to date.

How Bats’ Genomes May Help Them Avoid Cancer and Survive Viruses
A new study has analyzed the genomes of bats to investigate their ability to tolerate viral infections and avoid cancer – findings that could have implications for our knowledge of human cancers as well as virus transmission from animals.

Synthetic Biology Tool Comprehensively Reveals Gene Regulatory Networks
Pooled promoter responses to TF perturbation sequencing (PPTP-seq) is a new technique that integrates CRISPR gene editing with a combinatorial library containing every known transcription factor in the target genome and corresponding promoters.

Rise of "Hypervirulent" Strains of Klebsiella pneumoniae Investigated
Klebsiella pneumoniae causes a variety of afflictions and can be deadly. Researchers have now shown which strains are more likely to survive in human blood and serum, and which are more susceptible to the human immune system.
