Article Synopsis
- Brown dwarf companions to stars help us understand planet formation processes, but some of them are more massive than expected based on their luminosities and host star ages.
- Gliese 229 B, previously thought to be a single entity, was revealed through observations to actually be two brown dwarfs, Gliese 229 Ba and Bb, with masses of 38.1 and 34.4 Jupiter masses, respectively.
- This discovery challenges existing theories and raises questions about the formation and occurrence of binary brown dwarfs in close orbits around stars.
Legume roots allow intracellular infections of rhizobia to establish the mutualistic root nodule symbiosis. During this colonization event, specialized and membrane-defined infection threads provide the host-controlled path for the bacteria through the multilayered root tissue to reach a newly developing organ, the root nodule. On this way, bacteria have to propagate transcellularly and thus overcome cell wall barriers.

Radio detection and ranging-based (radar) sensing offers unique opportunities for biomedical monitoring and can help overcome the limitations of currently established solutions. Due to its contactless and unobtrusive measurement principle, it can facilitate the longitudinal recording of human physiology and can help to bridge the gap from laboratory to real-world assessments. However, radar sensors typically yield complex and multidimensional data that are hard to interpret without domain expertise.
