Baby and adult brains 'sync up' during play, finds Princeton Baby Lab
A team of Princeton researchers has conducted the first study of how baby and adult brains interact during natural play, and they found measurable connections in their neural activity.

Dermal sheath contraction powers stem cell niche relocation during hair cycle regression
Tissue homeostasis requires the balance of growth by cell production and regression through cell loss. In the hair cycle, during follicle regression, the niche traverses the skin through an unknown mechanism to reach the stem cell reservoir and trigger new growth. Here, we identify the dermal sheath that lines the follicle as the key driver of tissue regression and niche relocation through the sm

Observation of hydrogen trapping at dislocations, grain boundaries, and precipitates
Hydrogen embrittlement of high-strength steel is an obstacle for using these steels in sustainable energy production. Hydrogen embrittlement involves hydrogen-defect interactions at multiple-length scales. However, the challenge of measuring the precise location of hydrogen atoms limits our understanding. Thermal desorption spectroscopy can identify hydrogen retention or trapping, but data cannot

Observation of an isomerizing double-well quantum system in the condensed phase
Molecular isomerization fundamentally involves quantum states bound within a potential energy function with multiple minima.

Increasing rainfall and glacial meltwater could seriously disrupt the current, which has been slowing down for the past 150 years. Not all of the effects of an AMOC shutdown are clear, but it is likely that Europe will begin to see far colder winters should the
