Dinoflagellates, both armored and unarmored, with distinct cell wall difference, are being affected by elevated CO-induced ocean acidification (OA). However, their specific responses to OA are not well understood. In this study, we investigated the physiological and molecular response of the armored species Prorocentrum obtusidens and the unarmored species Karenia mikimotoi to OA over a 28-day period.

- The study investigates how the timing of sowing different crops (wheat and maize) affects their competitiveness and yield when intercropped compared to being grown separately.
- Field experiments were conducted over two years with various sowing times and planting methods, revealing that delaying wheat sowing reduced its yield while increasing maize's, yet wheat maintained a competitive edge during growth.
- Ultimately, aligning the sowing times of wheat and maize shifted their interaction from unbalanced to more mutually beneficial, but wheat still retained some competitive advantages despite these changes.
Article Synopsis
- - Nicotinamide phosphoribosyltransferase (NAMPT) is vital for producing nicotinamide adenine dinucleotide (NAD) and has been studied for its protective effects in neurodegeneration, particularly in Alzheimer's Disease, but its role in Parkinson's Disease (PD) is less understood.
- - Research indicates that dopaminergic neurons in the substantia nigra have higher NAMPT levels, and removing NAMPT leads to the loss of these neurons, dopamine pathway impairment, and symptoms similar to PD in mice.
- - The study suggests that NAD precursor nicotinamide ribose (NR) can counteract neurodegeneration in PD by repairing dopamine pathways and highlights the potential for using NAD precursors in

Article Synopsis
- The study investigates the genetic relationships within the walnut family (Juglandaceae) using data from seven chromosome-level genomes, including two newly assembled genomes.
