How computers push on the molecules they simulate
Because modern computers have to depict the real world with digital representations of numbers instead of physical analogues, to simulate the continuous passage of time they have to digitize time into small ...
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.
Humans, chimpanzees and monkeys share DNA but not gene regulatory mechanisms
Humans share over 90% of their DNA with their primate cousins. The expression or activity patterns of genes differ across species in ways that help explain each species' distinct biology and behavior.
Evolutionary oomph: Researchers describe way to create synthetic polymers using genetic coding in DNA
Scientists may soon be able to turn to one of the most powerful forces in biology—evolution—to help in their quest to develop new synthetic polymers.
Researchers makes advance in nanotech gene sequencing technique
(Phys.org) —The allure of personalized medicine has made new, more efficient ways of sequencing genes a top research priority. One promising technique involves reading DNA bases using changes in electrical ...
New method for mass-producing high-quality DNA molecules
A new method of manufacturing short, single-stranded DNA molecules can solve many of the problems associated with current production methods. The new method, which is described in the scientific periodical ...
DNA constructs antenna for solar energy
Researchers at Chalmers University of Technology have found an effective solution for collecting sunlight for artificial photosynthesis. By combining self-assembling DNA molecules with simple dye molecules, ...
New insight into the human genome through the lens of evolution
By comparing the human genome to the genomes of 34 other mammals, Australian scientists have described an unexpectedly high proportion of functional elements conserved through evolution.
Researchers improve the nanopore-based technology for detecting DNA molecules
If we wanted to count the number of people in a crowd, we could make on the fly estimates, very likely to be imprecise, or we could ask each person to pass through a turnstile. The latter resembles the model ...
Laser spotlight reveals machine 'climbing' DNA
(Phys.org)—New imaging technology has revealed how the molecular machines that remodel genetic material inside cells 'grab onto' DNA like a rock climber looking for a handhold.
Scientists fold RNA origami from a single strand
RNA origami is a new method for organizing molecules on the nanoscale. Using just a single strand of RNA, many complicated shapes can be fabricated by this technique. Unlike existing methods for folding DNA ...
Built-in 'self-destruct timer' causes ultimate death of messenger RNA in cells
Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered the first known mechanism by which cells control the survival of messenger RNA (mRNA) -- arguably biology's most important molecule. ...
Oh, my stars and hexagons! DNA code shapes gold nanoparticles
(Phys.org) -- DNA holds the genetic code for all sorts of biological molecules and traits. But University of Illinois researchers have found that DNA's code can similarly shape metallic structures.
Sea cucumbers and sea urchins could hold the key to looking young
Sea cucumbers and sea urchins are able to change the elasticity of collagen within their bodies, and could hold the key to maintaining a youthful appearance, according to scientists at Queen Mary, University of London.
