Study suggests carbon nanotubes may protect DNA from oxidation
(Phys.org)—Researchers at the National Institute of Standards and Technology (NIST) have provided evidence in the laboratory that single-wall carbon nanotubes (SWCNTs) may help protect DNA molecules from ...
New portable device enables RNA detection from ultra-small sample in only 20 minutes
A new power-free microfluidic chip developed by researchers at the RIKEN Advanced Science Institute (ASI) enables detection of microRNA from extremely small sample volume in only 20 minutes. By drastically ...
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.
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.
Training your robot the PaR-PaR way
Teaching a robot a new trick is a challenge. You can't reward it with treats and it doesn't respond to approval or disappointment in your voice. For researchers in the biological sciences, however, the future ...
Optical tweezers and sub-nanoscale precision: Following the process—and the consequence—of RNA folding
(Phys.org)—In a soundproofed, vibration-stabilized, temperature-controlled room, Stanford biophysicist Steven Block was watching a very small origami project.
Lipid droplets play an unexpected role in embryo development
New research at the University of Rochester reveals a new role for lipid roles, as well as a fundamental shift in the concept of histone balance.
Study questions feasibility of entire genome sequencing in minutes
The claim that nanopore technology is on the verge of making DNA analysis so fast and cheap that a person's entire genome could be sequenced in just minutes and at a fraction of the cost of available commercial methods, has ...
Engineers collaborate on inexpensive DNA sequencing method
(Phys.org)—Rapid, accurate genetic sequencing soon may be within reach of every doctor's office if recent research from the National Institute of Standards and Technology (NIST) and Columbia University's ...
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.
Proteins barge in to turn off unneeded genes
(Phys.org)—The sorcerer's apprentice started a water-carrying system, but couldn't stop it, and soon he was up to his neck in water, and trouble. Living cells have a better design: When they activate a ...
Molecular code cracked
(Phys.org) -- Scientists have cracked a molecular code that may open the way to destroying or correcting defective gene products, such as those that cause genetic disorders in humans.
Scientists use light to 'tag and track' genetic processes
(Phys.org) -- In a new study, UT Dallas researchers outline how they used fluorescent molecules to "tag" DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging ...
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.
