Argonne researchers posit way to locally circumvent Second Law of Thermodynamics

Universe started from low-entropy state. From the big bang, there is nowhere go but downhill.

In a microscopic level the physics can be time-symmetric (it seems not to be the case, there are T-symmetry violations), but macroscopically universe had higher entropy in the past (cosmological arrow of time)

edit: CPT-symmetry -> T-symmetry .

Which experiment saw CPT violation? CPT is a straightforward consequence of QFT with minimal assumptions.

Sorry, I meant T-symmetry violation, corrected.

Kaon decay and B mesons decay break CP-symmetry and a CP-symmetry violation is equivalent T symmetry violation (CPT symmetry is preserved only if CP-violation is paired with T-symmetry violation)
