Zirconium alloys are widely used as cladding material in nuclear reactors due to their neutron transparency. Now, it is shown that 88Zr has a surprisingly high neutron capture cross-section exceeding that of other zirconium isotopes by six orders of magnitude.
An inspired experimental approach sheds light on the formation of active turbulence in a system of microtubules and molecular motors. The emergent scaling behaviour takes us a step closer to understanding how activity begets turbulence.
Through stochastic resonance, noise-driven fluctuations make an otherwise weak periodic signal accessible. Experiments have now reported quantum stochastic resonance, which arises from intrinsic quantum fluctuations rather than external noise.
From disease proliferation to cell functioning, spreading dynamics on networks impact many collective phenomena. The joint contributions of the interaction structure and local dynamics have now been disentangled, revealing three distinct types of spreading pattern.
