How chromosomes unite p.568

The way in which chromosomes come together within a single nucleus after cell division has now been shown to involve a small DNA-binding protein named BAF, which might help to join chromosomes with one another.

Large quantum systems tamed p.569

Quantum-computing devices can be more powerful than their classical counterparts, but controlling large quantum systems is difficult. Two studies report work that overcomes this challenge.

A high-pressure situation for bacteria p.571

Analyses in mice suggest that dietary salt increases blood pressure partly by affecting some of the microbes that inhabit the gut. The implications of this work for hypertension warrant further study in humans.

Contactless health-care sensing p.572

A system for monitoring a person’s vital signs — such as their blood pressure and heart rate — offers many advantages over currently used technologies, including enhanced sensing capabilities, comfort and convenience.

Inequality has deep roots in Eurasia p.573

A study of 64 archaeological sites across four continents shows that the growth of agricultural and political systems provoked economic disparities, more so in Eurasia than in North America.

Methane upgraded by rhodium p.575

Rhodium catalysts have been developed that can be tuned to produce two different products from methane. The findings could aid the development of industrial processes that exploit this abundant resource.

Bulky tether proteins aid membrane fusion p.576

The energy source that drives vesicle fusion with a target organelle in vivo has been unclear. It emerges that proteins that tether fusing structures together also decrease the energy needed for the final fusion step.
