Manchester scientists tie the tightest knot ever achieved

Scientists at The University of Manchester have produced the most tightly knotted physical structure ever known - a scientific achievement which has the potential to create a new generation of advanced materials.

An elastomer that behaves like an artificial muscle

(Phys.org)—Animal muscle needs to be strong enough to endure strain; it must also be flexible and elastic; and it is self-healing. Finding a polymer that has all of these properties has proved challenging. However, researchers ...

Sculpting a conjugated polymer using DNA origami

(Phys.org)—New research allows scientists to sculpt polymers into two- and three-dimensional shapes, similar to how polypeptides fold into functional three-dimensional shapes. This ability is particularly advantageous for ...

New self-stretching material developed

Although most materials slightly expand when heated, there is a new class of rubber-like material that not only self-stretches upon cooling; it reverts back to its original shape when heated, all without physical manipulation.

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 School of Engineering ...

DNA molecules can detect pathogens, deliver drugs

(PhysOrg.com) -- First, Cornell researchers created DNA "bar codes" -- strands of the genetic material that quickly identify the presence of different molecules by fluorescing. Now, they have created new DNA molecules that ...
