The risks of blowing your own trumpet too soon on research
It was dubbed a "spectacular" discovery – even "Nobel prize-worthy".

Deceptive-looking vortex line in superfluid led to twice-mistaken identity
(Phys.org) —So long, solitons: University of Chicago physicists have shown that a group of scientists were incorrect when they concluded that a mysterious effect found in superfluids indicated the presence of solitons—exotic, solitary waves. Instead, they explain, the result was due to more pedestrian, whirlpool-like structures in the fluid. They published their explanation in the Sept. 19 issue of Physical Review Letters.

First dark matter search results from Chinese underground lab hosting PandaX-I experiment
Scientists across China and the United States collaborating on the PandaX search for dark matter from an underground lab in southwestern China report results from the first stage of the experiment in a new study published in the Beijing-based journal Science China Physics, Mechanics & Astronomy.

Now hear this: Simple fluid waveguide performs spectral analysis in a manner similar to the cochlea
(Phys.org) —Within the mammalian inner ear, or cochlea, a remarkable but and long-debated phenomenon occurs: As they move from the base of the cochlea to its apex, traveling fluid waves – that is, surface waves, in which (like waves on the sea and or in a canal) water moves both longitudinally and transversally – peak in amplitude at locations that depend on the wave's frequency. (Higher frequencies are concentrated in the base, lower frequencies in the apex.) What's critical is that these peaks allow us to identify and separate sounds. While cochlear frequency selectivity is typically explained by local resonances, this idea has two problems: resonance-based models require excessive intracochlear mass, and moreover cannot accurately represent the cochlea's production of both phase and amplitude information. Recently, however, Prof. Marcel van der Heijden at Erasmus Medical Center, University Medical Center, Rotterdam, has rejected resonance, and in its place has designed and fabricated a novel neural data-inspired approach to producing these frequency-dependent amplitude peaks in the form of a disarmingly simple waveguide that, in a manner analogous to an optical prism, carries fluid waves and performs spectral analysis. By incorporating a longitudinal gradient, the waveguide – which consists of two parallel fluid-filled chambers connected by a narrow slit spanned by two coupled elastic beams – separates frequencies and decelerates energy transport through wave dispersion, thereby focusing the peak-creating energy. Its novelty derives from its spectral analysis functionality being based not on resonance, nor on standing waves or geometric periodicity, but on mode shape swapping – an abrupt exchange of shapes between propagating wave modes – making it a new physical effect based on well-known physics.

Cold Atom Laboratory chills atoms to new lows
NASA's Cold Atom Laboratory (CAL) mission has succeeded in producing a state of matter known as a Bose-Einstein condensate, a key breakthrough for the instrument leading up to its debut on the International Space Station in late 2016.

Revisiting Stokes drift: Waves of the future
The 19th-century 'Stokes drift' concept that a tiny sphere on a small wave would trace a spiral, not a closed circle, was assumed to be unlikely to occur in nature. But using 21st-century technologies, scientists found that not only do the particles move, they move predictably, and can even be planned.

Entanglement made tangible
Scientists have designed a first-ever experiment for demonstrating quantum entanglement in the macroscopic realm. Unlike other such proposals, the experiment is relatively easy to set up and run with existing semiconductor devices.
