An enhanced production of particles with strange quarks has been observed in high-multiplicity proton–proton collisions — an important clue to understand how strange quarks form, and perhaps a hint of the quark–gluon plasma.

Quark–gluon plasma is an exotic state of matter that can emerge in heavy nuclei high-energy collisions. The ALICE collaboration reports the first observation of strangeness enhancement in proton–proton collisions, a possible signature of this state.

Using two entangled optical beams and post-selection, a single photon can have the same effect as eight photons in terms of the induced phase shift. This example illustrates the power of the so-called weak-value amplification.

When the entropy of a system scales as a function of its surface area, rather than its volume, it is said to obey an entropy area law. Now, an area law is shown to exist numerically in the entanglement entropy of superfluid helium.
