Squash is a versatile treat, but all too often, little spots of mold will start to appear and wreak havoc. Luckily, it's easy to keep it fresh for longer.
Whether you call them scallions or green onions, few items provide a meal with such flavor. But when it comes to storage, you should never freeze them.
In a recent analysis published in the British Medical Journal, Trisha Greenhalgh and colleagues explored inaccurate narratives of the mode of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission, propagating that it spreads through droplets and fomites but not air. The authors examined four complementary hypotheses to explain why these flawed narratives prevailed in the United Kingdom (UK) for so long.

The role of genetics
In developmental cell biology, the phrase “pattern formation” is used in reference to the propagation of complex organizations of cell fates in time and space. Pattern formation is mainly controlled via genes, such as homeobox type genes.
The vital role of genetics in pattern formation is a facet of morphogenesis: the creation of diversified anatomies from similar genes, which are now being examined in studies covering evolutionary developmental biology. The mechanisms that are involved can be observed in the anterior-posterior patterning of Drosophila melanogaster embryos, which were one of the first organisms to have had their morphogenesis studied.
