Phys.org / 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 ...

Phys.org / 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 ...

Phys.org / Gnaw-y by nature: Researchers discover neural circuit that rewards gnawing behavior in rodents

Researchers at the University of Michigan have discovered that the constant gnawing of rodents isn't just a reflex or a consequence of a tough diet. It also triggers a release of dopamine in the brain—which acts as a biochemical ...

Phys.org / Bacteria have a secret engineering trick to keep themselves in shape

Blow up a long balloon and two things happen: it gets longer and it gets wider. Now imagine a living cell that inflates itself under enormous pressure and yet only grows longer, never adding width. That is exactly what rod-shaped ...

Phys.org / Why lethal mutations persist: Fruit fly study points to newly transferred jumping genes, not small DNA errors

Most lethal mutations in wild fruit flies are driven by newly transferred jumping genes, not small DNA errors, according to a new study from Duke University. The findings, published in PLOS Biology, challenge decades of assumptions ...
