DNA as invisible ink can reversibly hide patterns
Engineers invent programming language to build synthetic DNA
Similar to using Python or Java to write code for a computer, chemists soon could be able to use a structured set of instructions to "program" how DNA molecules interact in a test tube or cell.
Siberian hamsters show what helps make seasonal clocks tick
Many animals, including humans, have internal clocks and calendars to help them regulate behavior, physiological functions and biological processes. Although scientists have extensively studied the timekeeping ...
The final nail in the Jurassic Park coffin: Next generation sequencing reveals absence of DNA in sub-fossilized insects
It is hardly possible to talk about fossil insects in amber without the 1993 movie Jurassic Park entering the debate. The idea of recreating dinosaurs by extracting DNA from insects in amber has held the ...
Researchers reconstruct mitochondrial genome of Middle Pleistocene cave bear
Researchers use DNA origami technique to build nanoantennas with docking sites
'Quadruple helix' DNA discovered in human cells
In 1953, Cambridge researchers Watson and Crick published a paper describing the interweaving 'double helix' DNA structure - the chemical code for all life. Now, in the year of that scientific landmark's 60th Anniversary, ...
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.
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.
Controlling heat flow through a nanostructure
MIT researchers find that heat moving in materials called superlattices behaves like waves; finding could enable better thermoelectrics.
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 ...
New type of extra-chromosomal DNA discovered
Physicists build highly efficient 'no-waste' laser
A team of University of California, San Diego researchers has built the smallest room-temperature nanolaser to date, as well as an even more startling device: a highly efficient, "thresholdless" laser that ...
Simpler times: Did an earlier genetic molecule predate DNA and RNA?
(PhysOrg.com) -- In the chemistry of the living world, a pair of nucleic acidsDNA and RNAreign supreme. As carrier molecules of the genetic code, they provide all organisms with a mechanism for ...
