One gene makes the difference: Breeding winter-hardy faba beans

An international research team involving the IPK Leibniz Institute has discovered a small yet significant genetic difference in faba beans. Whether a plant survives the winter or can only be grown in spring hinges on a single location in the genome. The results of the study, which could significantly speed up the development of hardy varieties, are published in the journal Nature Genetics.

Telomere breaks provide new insights into chaotic chromosome mutations

Researchers at Cardiff University have uncovered how a particularly severe form of DNA damage arises—shedding new light on mutation processes that contribute to cancer and inherited genetic conditions. The study, led by Dr. Greg Ngo and Professor Duncan Baird from Cardiff University's School of Medicine, reveals the mechanism behind chromoanasynthesis, a catastrophic type of chromosome rearrangement that leads to highly complex patterns of mutation.

Scientists control 'free-flowing' electric currents with light

By controlling magnetic fields using light, a team of researchers led by NTU scientists has solved a long-standing challenge to precisely direct electric currents produced by quantum materials. Their findings unlock new avenues for controlling the flow of electricity through such materials and could herald the age of energy-efficient quantum computing devices. The research is published in Nature in January.

A new model defines an upper limit to planetary radiation belt intensity

We all know that stars radiate light and much more. But radiation belts can also surround many other celestial bodies, such as planets. These belts do not generate particles themselves—the belts receive them from nearby stars—but they accelerate the speed of particles in a way that has remained elusive.

Soil health index finds restored mangroves can near full function

Brazilian researchers have developed an index that can measure the health of mangrove soils at different stages. When applied to degraded, restored, and preserved areas, the index revealed that healthy mangroves, including recovered ones, provide ecosystem services at nearly maximum capacity. In contrast, deforested mangroves have only a small fraction of this potential.
