In harvestmen, mothers and fathers did not follow the same path to guarding eggs—and a flood of citizen science records helped trace the split. phys.org/news/2026-06-devote…

Parental guarding appears to have evolved, vanished, and returned multiple times. Maternal care arose only from no care, while paternal care also emerged from maternal care, pointing to different pressures behind the behavior.

When discipline turns harsh, children may not become more honest—they may get better at hiding mistakes. @NUSingapore @srcdtweets phys.org/news/2026-06-reveal…

Across two long-term studies of Singaporean families, stricter control and harsh punishment were linked to more cheating and lying in childhood. The pattern appeared alongside self-criticism and pressure to avoid failure.

The wiring diagram connects every neuron in the central nervous system at synapse level. In early analyses, control of movement did not center in one brain hub. Much of it appeared within local circuits tied to specific body parts.

In some ultrathin materials, shaving thickness down to just a few layers can make them harder to deform under extreme loading. @PNASNews phys.org/news/2026-06-scalin…

A simple scaling law links that stiffening to confinement: as thickness shrinks, some collective deformation modes disappear. The added stiffness scales with the inverse cube of thickness, across very different ultrathin systems.

A key protein-folding partner helped insulin-making cells avoid a pileup of misfolded proinsulin—while extra help from its better-known partner did far less on its own. @sbpdiscovery @PNASNews medicalxpress.com/news/2026-…

The food, known as white chuño, forms only in high-altitude freezing conditions and can last for years. Found inside a storage jar at Tambo Viejo, the pair offers rare physical evidence of movement across the Inca empire.

The process starts with lignin from wood, then combines refinery-style steps with an engineered microbe. It produced about 26 wt% adipic acid, while earlier lignin routes to any single product often stalled near 20 wt%.

Women in the gated group received 6% fewer expressions of interest than the control group. But interactions improved, and women initiated more matches as screening time fell. The test tracked communication openings, not marriages.
