The major Atlantic current that keeps Northern Europe warm could have new variations and tipping points

Northern Europe is relatively warm given its place on the globe. For example, although north of most major Canadian cities, London is warmer than all of them (even Vancouver in British Columbia). But this warmth could disappear ...

Jojoba's survival strategy: How jasmonate boosts cold acclimation

Jojoba, a valuable industrial oil crop, is limited to tropical regions due to its sensitivity to low temperatures. Cold acclimation, where plants are exposed to low non-lethal temperatures, has shown the potential to improve ...
