Spider Silk Made by Photosynthetic Bacteria

A research team in Japan reported that they succeeded in producing the spider silk -- ultra-lightweight, though, biodegradable and biocompatible material -- using photosynthetic bacteria. This study ...

New Candidate for Raw Material Synthesis Through Gene Transfer

Cyanobacteria hardly need any nutrients and use the energy of sunlight. Bathers are familiar with these microorganisms as they often occur in waters. A group of researchers has discovered that the ...

Scientists Solve a Thorny Problem: Applications for Citrus Groves

''Why do plants have thorns?'' is an easy question: The thorns help protect against hungry animals that like to munch on the plants. ''Where do thorns come from?'' is a more complicated question -- ...
In a series of experiments using human cancer cell lines, scientists say they have successfully used light as a trigger to ...

Insect Wings Hold Antimicrobial Clues for Improved Medical Implants

Some insect wings such as cicada and dragonfly possess nanopillar structures that kill bacteria upon contact. However, to date, the precise mechanisms that cause bacterial death have been unknown. ...

Turning Cells Into Computers With Protein Logic Gates

New artificial proteins have been created to function as molecular logic gates. Like their electronic counterparts in computers, these biochemical tools can be used to program the behavior of complex ...

A Genetic Nano-Toolkit for the Generation of New Biomaterials

Magnetic bacteria might soon be used for the production of novel biomaterials. A team of microbiologists developed a modular system for the genetic reprogramming of bacteria, thereby turning the ...

New Viable CRISPR-Cas12b System for Plant Genome Engineering

A new CRISPR genome engineering system is viable in plants: CRISPR-Cas12b. The system is versatile, customizable, and ultimately provides effective gene editing, activation, and repression all in one ...

Genome Editing Strategy Could Improve Rice, Other Crops

Scientists have used CRISPR technology to genetically engineer rice with high levels of beta-carotene, the precursor of vitamin A. The technique they used provides a promising strategy for ...

Synthetic Biologists Redesign the Way Bacteria 'Talk' to Each Other

Bioengineers have redesigned how harmless E. coli bacteria ''talk'' to each other. The new genetic circuit could become a useful new tool for synthetic biologists who, as a field, ...

Improved CRISPR Gene Drive Solves Problems of Old Tech

Gene drives use genetic engineering to create a desired mutation in a few individuals that then spreads via mating throughout a population in fewer than 10 ...

CRISPR-HOT: A New Tool to 'Color' Specific Genes and Cells

Researchers have developed a new genetic tool to label specific genes in human organoids, or mini organs. They used this new method, called CRISPR-HOT, to investigate how hepatocytes divide and how ...

Computer-Generated Genomes

Chemists have described how computational algorithms paired with chemical DNA synthesis enable digital manufacturing of biological systems up to the size of entire microbial genomes. They have made ...

Computer Simulations Visualize How DNA Converts Cells Into Stem Cells

Researchers have revealed how an essential protein helps to activate genomic DNA during the conversion of regular adult human cells into stem ...

Efficient Cryopreservation of Genetically Modified Rat Spermatozoa

Researchers have developed a new technique to improve the efficiency of rat sperm cryopreservation, a process that is usually extremely difficult. Their technique makes it possible to produce more ...

Bacteria Engineered to Protect Bees from Pests and Pathogens

Scientists report that they have developed a new strategy to protect honey bees from a deadly trend known as colony collapse: genetically engineered strains of bacteria. This is the first time anyone ...

Opening Up DNA to Delete Disease

Protein editorial assistants are clearing the way for cut-and-paste DNA editors, like CRISPR, to access previously inaccessible genes of interest. Opening up these areas of the genetic code is ...

Poplar Genetically Modified Not to Harm Air Quality Grow as Well as Non-Modified Trees

Field trials in Oregon and Arizona show that poplar trees, which emit trace amounts of the gas isoprene, can be genetically modified not to harm air quality while leaving their growth potential ...

'Upgraded' CRISPR Tool

Scientists have captured the first images of a new gene editing tool that could improve upon existing CRISPR-based ...

Disruption of Glycine Receptors to Study Embryonic Development and Brain Function

Researchers are studying glycine receptors, particularly glycine receptor alpha-4 (Glra4), during development. They demonstrated, in a new study, that Glra4 is not a brain exclusive gene, as was ...

A New Gene Therapy Strategy, Courtesy of Nature

Scientists have developed a new gene-therapy technique by transforming human cells into mass producers of tiny nano-sized particles full of genetic material that has the potential to reverse disease ...

High-Tech Method for Uniquely Targeted Gene Therapy Developed

Neuroscientists have developed new technology that engineers the shell of a virus to deliver gene therapy to the exact cell type in the body that needs to be treated. The researchers believe that the ...

New Marker for Insecticide Resistance in Malaria-Carrying Mosquitoes

Researchers have genetically modified malaria carrying mosquitoes in order to demonstrate the role of particular genes in conferring insecticide ...

Cell-Free Synthetic Biology Comes of Age

New research explores how cell-free gene expression stands to help the field of synthetic biology dramatically impact society, from the environment to medicine to ...
