How to build a better dad p.418

Oldfield mice and deer mice differ in their parental care, most dramatically in the behaviour of fathers. A study reveals the genetic and neuronal contributions to variation in parental care. See Article p.434

Strangeness in the proton p.419

The proton can contain pairs of elementary particles known as strange quarks. The contribution of these particles to the proton's electric-charge distribution and magnetic moment has been determined.

Unexpectedly early signs of Americans p.420

Humans are thought to have reached the Americas less than 15,000 years ago. But evidence of stone tool use on an animal carcass excavated in California points to a much earlier arrival of human relatives from the genus Homo. See Letter p.479

Severe weather in a warming climate p.422

During the past few decades, the Sahara Desert has become even hotter. Satellite observations suggest that this warming has led to a rise in the frequency of extreme storms in the Sahel region of West Africa. See Letter p.475

A larger palette for biological imaging p.423

Biological molecules are often imaged by attaching fluorescent labels — but only a few label types can be used at a time. A method that could smash the record for the number of labels that can be used together is now reported. See Letter p.465

Genomic compartments in barley p.424

A high-quality barley genome reveals a surprising compartmentalization of genes and repetitive sequences in chromosomes. This advance paves the way for improved genetic optimization of cereals. See Article p.427

A universal model for solar eruptions p.452

Simulations of a solar coronal jet driven by filament ejection demonstrate that magnetic reconnection underlies the energy release, implying that a universal ‘breakout’ model explains both tiny jets and huge mass ejections from the Sun.

Super-multiplex vibrational imaging p.465

Stimulated Raman scattering under electronic pre-resonance conditions, combined with a new palette of probes, enables super-multiplex imaging of molecular targets in living cells with very high vibrational selectivity and sensitivity.

Abrasion-set limits on Himalayan gravel flux p.471

The amount of coarse gravel transported out of the Himalayan mountains by rivers is insensitive to catchment size, because the majority of gravel sourced more than 100 kilometres upstream of the mountain front is abraded into sand before it reaches the Ganga Plain.
