Jagged graphene edges can slice into cell membranes

(Phys.org) —A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the cell and disrupt ...

Engineers create structures tougher than bulletproof vests

Researchers at UT Dallas have created new structures that exploit the electromechanical properties of specific nanofibers to stretch to up to seven times their length, while remaining tougher than Kevlar.

Bending diamond is possible, at the nanoscale

Diamond is prized by scientists and jewelers alike, largely for a range of extraordinary properties including exceptional hardness. Now a team of Australian scientists has discovered diamond can be bent and deformed, at the ...

A renewable bioplastic made from squid proteins

In the central Northern Pacific is an area that may be the size of Texas called the Great Pacific Garbage Patch. Made up of tons of floating plastic debris, the patch is killing seabirds and poisoning marine life in the North ...

Scientists unravel the mysterious mechanics of spider silk

Scientists now have a better understanding of why spider silk fibers are so incredibly strong. Recent research, published by Cell Press on February 15th in Biophysical Journal, describes the architecture of silk fibers from ...

Strength is shore thing for sea shell scientists

(PhysOrg.com) -- Scientists have made synthetic 'sea shells' from a mixture of chalk and polystyrene cups - and produced a tough new material that could make our homes and offices more durable.
