Polymers are an effective test bed for studying topological constraints in condensed matter due to a wide array of synthetically available chain topologies. When linear and ring polymers are blended together, emergent rheological properties are observed as the blend can be more viscous than either of the individual components. This emergent behavior arises since ring-linear blends can form long-lived topological constraints as the linear polymers thread the ring polymers.

With the death of famed Los Angeles personal injury lawyer Larry H. Parker, the Southern California law community said goodbye to a ubiquitous figure who for 50 years used billboards, buses and television advertisements throughout the region to promise clients he would fight for them. For some Los Angeles attorneys, that means bidding farewell to one of their earliest legal inspirations. “I never worked with Larry H. Parker but growing up ...

AbstractIn mammalian cells, the cohesin protein complex is believed to translocate along chromatin during interphase to form dynamic loops through a process called active loop extrusion. Chromosome conformation capture and imaging experiments have suggested that chromatin adopts a compact structure with limited interpenetration between chromosomes and between chromosomal sections.

But they’re not indestructible. Enough strain and they begin to crack. Most methods to make such materials more durable invariably involve a trade-off, Craig said: Greater toughness for less elasticity, for example. The new study suggests it doesn’t always have to be a compromise. The secret lies in weak bonds embedded within the material that actually make it stronger. Zoom in close enough, and elastomers essentially look like a jumble of loosely coiled strings or strands of spaghetti.
