Viewpoint A Cut Above the Rest
Experienced chefs know that to make a neat cut in a boiled egg or a piece of cheese, a thin wire, or even a fine piece of thread, can work better than a knife. But even a blunt knife can cut soft solids well if it is rocked back and forth while applying a gentle pressure. Understanding the balance of forces needed to make a clean cut into deformable materials could be important for developing h...
متن کاملA cut above
A new technique called CUT&RUN can map the distribution of proteins on the genome with higher resolution and accuracy than existing approaches.
متن کاملOogenesis: Setting one sister above the rest
Recent studies have revealed that the Par-1 protein, in addition to its established role in anterior-posterior patterning of the Drosophila oocyte, has both microtubule-dependent and microtubule-independent roles very early in oogenesis.

Human pluripotent stem cells (hPSCs) offer unprecedented opportunities to study cellular differentiation and model human diseases. The ability to precisely modify any genomic sequence holds the key to realizing the full potential of hPSCs. Thanks to the rapid development of novel genome editing technologies driven by the enormous interest in the hPSC field, genome editing in hPSCs has evolved f...
متن کاملApproximating Almost All Instances of Max-Cut Within a Ratio Above the Håstad Threshold
We give a deterministic polynomial-time algorithm which for any given average degree d and asymptotically almost all random graphs G in G(n,m = d2n ) outputs a cut of G whose ratio (in cardinality) with the maximum cut is at least 0.952. We remind the reader that it is known that unless P=NP, for no constant > 0 is there a Max-Cut approximation algorithm that for all inputs achieves an approxim...
