Artificial molecular machine could hold key to more efficient manufacturing (w/ video)
An industrial revolution on a minute scale is taking place in laboratories at The University of Manchester with the development of a highly complex machine that mimics how molecules are made in nature.
Researchers demonstrate possible primitive mechanism of chemical info self-replication
(Phys.org) -- When scientists think about the replication of information in chemistry, they usually have in mind something akin to what happens in living organisms when DNA gets copied: a double-stranded molecule ...
Hydrogel remembers its shape
(Phys.org)—A bit reminiscent of the Terminator T-1000, a new material created by Cornell researchers is so soft that it can flow like a liquid and then, strangely, return to its original shape.
Two-step technique makes graphene suitable for organic chemistry
The future brightened for organic chemistry when researchers at Rice University found a highly controllable way to attach organic molecules to pristine graphene, making the miracle material suitable for a ...
Controlling heat flow through a nanostructure
MIT researchers find that heat moving in materials called superlattices behaves like waves; finding could enable better thermoelectrics.
Dog skull dates back 33,000 years
If you think a Chihuahua doesn't have much in common with a Rottweiler, you might be on to something.
Researchers suspend, image single DNA molecules
(PhysOrg.com) -- Studying chemical modifications in the chromosomes of cells is akin to searching for changes in coiled spaghetti. Scientists at Cornell have figured out how to stretch out tangled strands ...
Researchers develop strategy for targeted drug delivery
Researchers at the University of Twente's MESA+ research institute have developed a new strategy for delivering drugs to specific areas of the body in a targeted way. They have created a carrier that, in ...
Nanopore opens new cellular doorway for drug transport
A living cell is built with barriers to keep things out – and researchers are constantly trying to find ways to smuggle molecules in. Professor Giovanni Maglia (Biochemistry, Molecular and Structural ...
Students use physics to unpack DNA, one molecule at a time
If two individuals have the same genetic predisposition for breast cancer, why does one person develop cancer while the other does not?
Researchers use virus to reveal nanopore physics
Nanopores may one day lead a revolution in DNA sequencing. By sliding DNA molecules one at a time through tiny holes in a thin membrane, it may be possible to decode long stretches of DNA at lightning speeds. ...
Designer piercings: New membrane pores with DNA nanotechnology
A new way to build membrane-crossing pores, using Lego-like DNA building blocks, has been developed by scientists at UCL, in collaboration with colleagues at the University of Cambridge and the University of Southampton.
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 ...
Nanostructures made of DNA strands can encapsulate, release small-molecule drugs
Nanoscale "cages" made from strands of DNA can encapsulate small-molecule drugs and release them in response to a specific stimulus, McGill University researchers report in a new study.
