The Ancient Love Story That Created the Potato and Changed Human History

The researchers report that hominin teeth, especially molars, became smaller and longer over millennia to accommodate a growing diet of tough grass-like plants known as graminoids and their underground storage organs. They found the turn toward grasses began about 3.8 million years ago with the distant human relative Australopithecus afarensis (left). About 2.3 million years ago, the early human Homo rudolfensis (center) gained regular access to carbohydrate-rich underground plant organs such as tubers, bulbs, and corms. But this dietary shift toward outpaced tooth evolution until about 2 million years ago when species such as Homo ergaster (right) exhibited a spurt of change in tooth size and shape better suited to eating and breaking down cooked plant tissues to derive their nutrients.

Your Brain Can Trigger an Immune Response Without You Getting Sick

Cortical thickness map of a representative control participant and a patient with MDD. A medial and lateral view of the left hemisphere are illustrated on the left side of the image. In the center is a top view. A corresponding view of the right hemisphere is shown on the right. Boundaries of the Desikan-Killiany DK-40 atlas are outlined in black. The PHC is highlighted by an arrow. Significant intergroup differences were found in the left hemispheric PHC thickness. Neuroticism was correlated negatively with both left and right hemispheric PHC thickness. Credit: Translational Psychiatry (2025). DOI: 10.1038/s41398-025-03435-y

Glitches in PSR J0007+7303. The top panel shows the frequency residual (∆ν), the middle panel represents the evolution of frequency residual (∆ν) after removing mean frequency of post-glitch, the bottom panel is the derivative of the spin frequency, with the mean value removed. The vertical dashed lines represent the glitches epoch. Credit: arXiv (2025). DOI: 10.48550/arxiv.2507.18187
