Researcher develops novel strategy to improve crops and treat diseases
A novel strategy to enhance genome editing promises to increase the efficiency of making genetic improvements in a wide range of organisms, a new study suggests.
Untangling DNA with a droplet of water, a pipet and a polymer
Researchers have long sought an efficient way to untangle DNA in order to study its structure - neatly unraveled and straightened out - under a microscope. Now, chemists and engineers at KU Leuven, in Belgium, ...
Link identified between virus recognition, destruction in bacterial immune system
An immune system that helps bacteria combat viruses is yielding unlikely results such as the ability to edit genome sequences and potentially correct mutations that cause human disease.
We're all mammals – so why do we look so different?
It is easy to distinguish a mouse from a cow. But for members of the same class of mammal, where do such differences begin? In 2011, scientists discovered there were differences in cow and mice blastocysts, the ti ...
'Fibonacci quasiparticle' could form basis of future quantum computers
Researchers create unique graphene nanopores with optical antennas for DNA sequencing
(Phys.org) —High-speed reading of the genetic code should get a boost with the creation of the world's first graphene nanopores – pores measuring approximately 2 nanometers in diameter – that feature ...
Scientists make enzyme that could help explain origins of life
Mimicking natural evolution in a test tube, scientists at The Scripps Research Institute (TSRI) have devised an enzyme with a unique property that might have been crucial to the origin of life on Earth.
Breakthrough shows how DNA is 'edited' to correct genetic diseases
An international team of scientists has made a major step forward in our understanding of how enzymes 'edit' genes, paving the way for correcting genetic diseases in patients.
'Aliens of sea' provide new insight into evolution
Exotic sea creatures called comb jellies may reshape how scientists view early evolution—as their genes suggest nature created more than one way to make a nervous system.
Charged graphene gives DNA a stage to perform molecular gymnastics
(Phys.org) —When Illinois researchers set out to investigate a method to control how DNA moves through a tiny sequencing device, they did not know they were about to witness a display of molecular gymnastics.
Bacteria become 'genomic tape recorders'
MIT engineers have transformed the genome of the bacterium E. coli into a long-term storage device for memory. They envision that this stable, erasable, and easy-to-retrieve memory will be well suited for ap ...
Coffee genome sheds light on the evolution of caffeine
Enzymes that help produce caffeine evolved independently in coffee, tea and chocolate, say scientists who have newly sequenced the coffee plant genome.
New material could enhance fast and accurate DNA sequencing
Gene-based personalized medicine has many possibilities for diagnosis and targeted therapy, but one big bottleneck: the expensive and time-consuming DNA-sequencing process.
Design of self-assembling protein nanomachines starts to click
(Phys.org) —A route for constructing protein nanomachines engineered for specific applications may be closer to reality.
