Unveiling the giant: tibetan wild peony genome sheds light on floral evolution

A new study has decoded the complex genome of the Tibetan wild tree peony (Paeonia ludlowii), revealing its evolutionary history and the genetic drivers behind its unique traits. This comprehensive genomic resource could transform tree peony breeding and shed light on how plants adapt to high-altitude environments. The research unveils the genome’s intricate structure, emphasizing the crucial role of transposable elements and DNA methylation in shaping the genetic diversity of this rare species.

Researchers create human aortic aneurysm model to advance disease understanding, treatment testing

There are currently no medical treatments for thoracic aortic aneurysm. Using human cells in laboratory rats, researchers have developed a functional model of thoracic aortic aneurysm, creating opportunities for more effective understanding of disease development and treatments for the potentially fatal condition, a study suggests.

Pequenos primatas com faces mais expressivas do que se pensava

Universidade de Quioto adaptou o sistema humano de codificação de acção facial, ou FACS, como uma ferramenta para comparações sistemáticas de músculos faciais entre espécies. As contrações musculares faciais movem porções da pele, produzindo um conjunto de mudanças de aparência que são visíveis no rosto. O FACS analisa e classifica os movimentos visíveis feitos pelos músculos faciais através das chamadas unidades de acção.
